    Perineural ganglion impar injections are used in the management of pelvic pain syndromes; however, there is no consensus regarding the optimal image guidance. Magnetic resonance imaging (MRI) provides high soft tissue contrast and the potential to directly visualize and target the ganglion. The purpose of this study was to assess the feasibility of MR-guided percutaneous perineural ganglion impar injections. Six MR-guided ganglion impar injections were performed in six human cadavers. Procedures were performed with a clinical 1.5-Tesla MRI system through a far lateral transgluteus approach. Ganglion impar visibility, distance from the sacrococcygeal joint, number of intermittent MRI control steps required to place the needle, target error between the intended and final needle tip location, inadvertent punctures of non-targeted vulnerable structures, injectant distribution, and procedure time were determined. The ganglion impar was seen on MRI in 4/6 (66 %) of cases and located 0.8 mm cephalad to 16.3 mm caudad (average 1.2 mm caudad) to the midpoint of the sacrococcygeal joint. Needle placement required an average of three MRI control steps (range, 2-6). The average target error was 2.2 ± 2.1 mm. In 6/6 cases (100 %), there was appropriate periganglionic distribution and filling of the presacrococcygeal space. No punctures of non-targeted structures occurred. The median procedure time was 20 min (range, 12-29 min). Interventional MRI can visualize and directly target the ganglion impar for accurate needle placement and successful periganglionic injection with the additional benefit of no ionizing radiation exposure to patient and staff. Our results support clinical evaluation. (orig.)

    Full Text Available Introduction: Injury during peripheral nerve blocks is relatively uncommon, but potentially devastating complication. Recent studies emphasized that location of needle insertion in relationship to the fascicles may be the predominant factor that determines the risk for neurologic complications. However, it is wellestablished that concentration of local anesthetic is also associated with the risk for injury. In this study, we examined the effect of location of injection and concentration of Ropivacaine on risk for neurologic complications. Our hypothesis is that location of the injection is more prognostic for occurrence of nerve injury than the concentration of Ropivacaine.Methods: In experimental design of the study fi fty Wistar rats were used and sciatic nerves were randomized to receive: Ropivacaine or 0.9% NaCl, either intraneurally or perineurally. Pressure data during application was acquired by using a manometer and was analyzed using software package BioBench. Neurologic examination was performed thought the following seven days, there after the rats were sacrificed while sciatic nerves were extracted for histological examination.Results: Independently of tested solution intraneural injections in most of cases resulted with high injection pressure, followed by obvious neurologic defi cit and microscopic destruction of peripheral nerves. Also, low injection pressure, applied either in perineural or intraneural extrafascicular area, resulted with transitory neurologic defi cit and without destruction of the nerve normal histological structure.Conclusions: The main mechanism which leads to neurologic injury combined with peripheral nerve blockade is intrafascicular injection. Higher concentrations of Ropivacaine during intrafascicular applications magnify nerve injury.

    Perineural spread is the dissemination of some types of head and neck tumors along nervous structures. Perineural spread has negative repercussions on treatment because it requires more extensive resection and larger fields of irradiation. Moreover, perineural spread is associated with increased local recurrence, and it is considered an independent indicator of poor prognosis in the TNM classification for tumor staging. However, perineural spread often goes undetected on imaging studies. In this update, we review the concept of perineural spread, its pathogenesis, and the main pathways and connections among the facial nerves, which are essential to understand this process. Furthermore, we discuss the appropriate techniques for imaging studies, and we describe and illustrate the typical imaging signs that help identify perineural spread on CT and MRI. Finally, we discuss the differential diagnosis with other entities. Copyright © 2013 SERAM. Published by Elsevier Espana. All rights reserved.

    Perineural spread is well known to be the most insidious form of tumour spread of a number of head and neck malignancies. However, perineural extension of nasopharyngeal carcinoma (NC) is a poorly recognized event. Four cases of perineural metastases from NC have been detected with pluridirectional tomography and CT. In 3 cases involvement of the Vidian nerve (nervus canalis pterygoidei) and pterygoid canal was observed. In a fourth patient, invasion of one pterygopalatine fossa and perineural spread along ipsilateral maxillary nerve with enlargement and erosion of the foramen rotundum was demonstrated. Radiological diagnosis of clinically unsuspected perineural tumour spread is important because it markedly influences treatment planning and prognosis of NC.

    To describe a 4-year clinical experience with ultrasound-guided therapeutic perineural injections of peripheral nerves about the foot and ankle. Retrospective analysis of foot and ankle perineural injections performed between January 2012 and August 2016. Demographics, clinical indications, presence of structural pathology, immediate and interval pain relief, as well as complications were recorded. Fifty-nine therapeutic injections were performed among 46 patients, accounting for multiple injections in a single visit or multiple visits [mean age = 43 years (range 18-75), 31 female (67%) and 15 male (33%)]. Most commonly, perineural injections involved the hallux branch of the medial plantar nerve (n = 17, 22%). Least commonly, perineural injections involved the saphenous nerve (n = 3, 4%). Other injections in our series include sural (10), superficial (11) and deep (7) peroneal, medial (5) and lateral (3) plantar nerves, and the posterior tibial nerve (3). Ultrasound evaluation revealed structural abnormality associated with the nerve in 30 cases (51%)-most commonly thickening with perineural scarring (n = 14). Of 45 injections with complete documentation, immediate relief of symptoms was reported in 43 (96%) cases. Interval symptom relief was achieved in 23 injections [short term (n = 12), intermediate (n = 6), and long term (n = 5)] out of 38 for which follow-up was available (61%). Complications are rare, occurring in only one case. Ultrasound-guided perineural injections about the foot and ankle are safe and provide lasting symptomatic relief for many indications. Concomitant sonographic evaluation identifies structural abnormalities that may contribute to neuropathic symptoms, allowing targeting of injection or clinical therapy.

    Piriformis syndrome is a common cause of lumbar, gluteal, and thigh pain, frequently associated with sciatic nerve symptoms. Potential etiologies include muscle injury or chronic muscle stretching associated with gait disturbances. There is a common pathological end pathway involving hypertrophy, spasm, contracture, inflammation, and scarring of the piriformis muscle, leading to impingement of the sciatic nerve. Ultrasound-guided piriformis injections are frequently used in the treatment of these pain syndromes, with most of the published literature describing injection of the muscle. We describe a safe, effective ultrasound-guided injection technique for the treatment of piriformis syndrome using targeted sciatic perineural hydrodissection followed by therapeutic corticosteroid injection.

    Full Text Available Aims. To elucidate characteristics of IgG4-related disease involving the peripheral nervous system. Methods. Retrospective review of 106 patients with IgG4-related disease identified 21 peripheral nerve lesions in 7 patients. Clinicopathological and radiological features were examined. Results. Peripheral nerve lesions were commonly identified in orbital or paravertebral area, involving orbital (=9, optic (=4, spinal (=7, and great auricular nerves (=1. The predominant radiological feature was a distinct perineural soft tissue mass, ranging 8 to 30 mm in diameter. Histologically, the epineurium was preferentially involved by massive lymphoplasmacytic infiltration rich in IgG4+ plasma cells. All lesions were neurologically asymptomatic and steroid-responsive at the first presentation, but one recurrent lesion around the optic nerve caused failing vision. Conclusion. IgG4-related disease of the peripheral nervous system is characterized by orbital or paravertebral localization, perineural mass formation, and rare neurologic symptoms. The term “IgG4-related perineural disease” seems appropriate to describe this entity.

    Full Text Available Introduction. Syphilis is a sexually transmitted disease that is known as “the great imitator” due to its wide variety of clinical presentations, including ocular disorders. There has been an increase in the rate of syphilis in the United States, especially in persons with HIV. We report a case of optic perineuritis in an asymptomatic male secondary to central nervous system (CNS syphilis. Case Report. A 41-year-old man was found to have bilateral disc edema on a routine exam. Brain MRI was unremarkable, and lumbar puncture revealed a normal opening pressure, with an elevated cerebrospinal fluid white cell count. Orbit MRI showed optic nerve sheath expansion and enhancement, consistent with optic perineuritis. He tested positive for syphilis based on serum RPR and FTA-ABS. Conclusion. Ophthalmologic findings, including disc edema, may be the presenting features of CNS syphilis. Even in asymptomatic persons, perineuritis should be considered early, as diagnosis and treatment are imperative given the progressive nature of the disease.

    Optic perineuritis is an uncommon inflammatory disorder that involves optic nerve sheath. Numerous case reports have been published on optic perineuritis in adults, the majority of whom had bilateral presentation. There are limited data on optic perineuritis occurring in pediatric patients. We report a teenager who presented with a unilateral sign that mimicked the presentation of optic neuritis. The orbit and brain magnetic resonance imaging confirmed features of unilateral optic perineuritis. She was treated with a high dose of corticosteroids for 2weeks, and her final visual outcome was satisfactory. No signs of relapse were noted during follow-up visits.

    Full Text Available Abstract Introduction It has been reported that the prognosis of optic perineuritis may be poor when initiation of treatment is delayed. Here we report the successful treatment of three patients with idiopathic optic perineuritis, including two in whom initiation of therapy was delayed. Case presentation Three Japanese patients (two women aged 73 and 66 years, and one man aged 27 years presented with loss of vision (for five months, several months, and two months respectively and pain on eye movement in the third case only, and were diagnosed as having idiopathic optic perineuritis. Fat-suppressed T2-weighted magnetic resonance images showed high signal intensity areas around the affected optic nerves, suggesting the presence of optic perineuritis. Two patients received steroid pulse therapy and the third was given high-dose steroid therapy. The visual acuity improved in all three cases. Conclusion High-dose steroid therapy may be effective for idiopathic perineuritis in patients without optic nerve atrophy, even if initial treatment (including moderate-dose steroids has failed.

    Full Text Available Optic perineuritis is an orbital inflammatory disorder that is either idiopathic or secondary to other conditions such as infection or systemic inflammatory disorders. This condition is very similar to demyelinating optic neuritis, but certain features of the history and magnetic resonance imaging findings are characteristic for and aid in the diagnosis of optic perineuritis. Vision loss varies greatly, from minimal clouding of vision up to only light perception. We report a case of a 44-year-old female with idiopathic bilateral optic perineuritis with vision loss of up to no light perception in both eyes. Radio imaging studies were typical of optic perineuritis and she was started on systemic corticosteroids. She responded very well to steroid therapy and achieved nearly complete visual recovery. There had been no relapse despite cessation of therapy.

    1988-01-01

    The third division of the trigeminal nerve exists through the foramen ovale and supplies extensive superficial and deep facial structures. As such, it is a common route of perineural spread of head and neck tumors. Perineural tumor extension through basal foramina is well documented pathologically and has been described with multiple radiologic modalities. The authors present seven patients with transforaminal lesions evaluated with MR imaging. Clinical findings referable to the two dimensions of V 3 are correlated with the images. This paper focuses on the normal anatomy and pathologic findings in and around the foramen ovale

  14. Proposed mechanism of action for twin mix anaesthesia when used as intra-space pterygomandibular injection for inferior alveolar nerve block with emphasis on effects of perineural injection of dexamethasone

    2018-01-01

    Full Text Available There has been recent research on the use of dexamethasone as an adjunct to local anaesthetics to enhance the block characteristics and improve post-operative pain outcomes. Numerous studies have shown that perineural dexamethasone improves post-operative analgesia, along with other clinical benefits. Intra-space pterygomandibular twin mix anaesthesia is a novel technique for inferior alveolar nerve block used for mandibular anaesthesia. Twin mix anaesthesia has its advantages in shortening the latency and prolonging the duration of the soft tissue anaesthesia, along with improving the quality of life in the post-operative period after mandibular oral surgical procedures. The concern regarding the use of perineural dexamethasone has been discussed.

  15. Injection Pressure as a Marker of Intraneural Injection in Procedures of Peripheral Nerves Blockade

    2006-11-01

    Full Text Available The blockade of peripheral nerves carries a certain risk of unwanted complications, which can follow after unintentional intraneural injection of a local anesthetic. Up till today, the research of measuring injection pressure has been based on animal models, even though the histological structure of periphery nerve is different for animal and human population, so the application pressure which presages intraneural injection in human population is still unknown. As material in performing this study there have been used 12 Wistar rats and 12 delivered stillborns. After bilateral access to the median nerve, we applied 3 ml of 2% lidocaine with epinephrine, with the help of automatic syringe charger. The needle was at first placed perineural on one side, and then intraneural on the other side of both examination groups. During every application the pressure values were monitored using the manometer, and then they were analyzed by special software program BioBench. All perineural injections resulted with the pressure < or = 27.92 kPa, while the majority of intraneural injections were combined with the injectionpressure > or = 69.8 kPa. The difference between intraneural and perineural injection pressures for the two different examination groups (rats and delivered stillborns was not statistically significant (P>0.05. As prevention from intraneural injections today are in use two methods: the method of causing paresthesia or the method of using the peripheral nerve stimulator. However the nerve injury can still occur, independent from the technique used. If our results are used in clinical practice on human population, than the high injection pressure could be the markerof intraneural lodging of a needle.

  16. Which features of advanced head and neck basal cell carcinoma are associated with perineural invasion?

    Directory of Open Access Journals (Sweden)

    André Bandiera de Oliveira Santos

    Full Text Available Abstract Introduction Perineural invasion is a unique route for tumor dissemination. In basal cell carcinomas, the incidence is low, but increases in advanced cases. Its importance is recognized but not fully understood. Objective To compare head and neck basal cell carcinomas with and without perineural invasion. Methods A retrospective medical chart review of multidisciplinary surgeries for basal cell carcinomas that required a head and neck surgery specialist in a tertiary referral center was performed. Clinical-demographics and histopathological features were analyzed. Results Of 354 cases, perineural invasion was present in 23.1%. Larger tumors and morpheaform subtype were statistically related to perineural invasion. Nodular and superficial subtypes were less frequent in positive cases. No significant difference was found in gender, age, ulceration, location, and mixed histology. Conclusion In this series of selected patients with basal cell carcinomas submitted to major resections, perineural invasion was clearly related to morpheaform subtype and to larger tumors. Other classically associated features, such as location in high-risk mask zone of the face, male gender and mixed histology, were not so strongly linked to perineural invasion.

    This article provides an overview of perineural spread of head and neck malignancy. It defines the problem and explores some of the unique features, which occur with this pathology. The expectation is for a better understanding of this extraordinary disease, hopefully leading to earlier diagnosis and for a more consistent reporting of results. It summarizes the topics to be covered in this special edition, which should leave the reader with a fairly complete understanding of the contemporary issues of perineural spread.

    The association between morphea and perineural inflammation has been reported sporadically but never studied systematically. To assess the prevalence and nature of perineural inflammation in various clinicopathologic stages of morphea and a cohort of other inflammatory dermatoses, 80 morphea and 36 control skin biopsies were studied using hematoxylin/eosin and S100 stains. Perineural inflammation was semiquantitatively analyzed (scored), which along with the pattern (concentric vs. marginal) and cellular composition was compared in the two groups. Perineural inflammation was identified in 84% and 61% of morphea and control cases, respectively. Examination of only routinely stained sections could still detect this feature in 58% of morphea and 33% of control biopsies. Mean perineural inflammation score in morphea (0.65) was significantly higher than in the control group (0.23) (p morphea cases. Although perineural inflammation is common in morphea, it is not unusual to find this feature in other inflammatory conditions. Nevertheless, perineural inflammation can serve as an important diagnostic adjunct in difficult cases of morphea if one considers its greater intensity, predominantly concentric pattern and the tendency to show plasma cell neurotropism. © 2013 John Wiley & Sons A/S.

    To determine the short-term effect of fluoroscopic-guided steroid injection therapy of lumbar facet cyst-induced radicular pain. Seventeen patients with radiculopathy due to lumbar synovial cysts, who were treated with fluoroscopically guided injection, were retrospectively evaluated. All plain radiographic images and MR images before the therapy were reviewed. Five patients underwent only the facet joint injection, whereas twelve patients underwent the facet joint injection with perineural injection therapy. The clinical course of pain was evaluated on the first follow-up after therapy. Effective pain relief was achieved in 11 (64.7%) of the 17 patients. Among 12 patients who underwent facet joint injection with perineural injection, 9 patients (75%) had an effective pain relief. Of 5 patients, 2 (40%) patients only took the facet joint injection and had an effective pain relief. Fluoroscopic-guided steroid injection therapy shows a good short-term effect in patients with symptomatic lumbar facet joint synovial cysts.

    1999-01-01

    Purpose: To address outcomes in clinically asymptomatic patients in whom the unexpected finding of microscopic perineural invasion is noted at the time of surgery. Methods and Materials: The 35 patients included in this study had skin cancers of the head and neck treated with curative intent between January 1965 and April 1995 at the University of Florida. All patients were without clinical or radiographic evidence of perineural invasion but, at the time of biopsy or surgical excision, had the incidental finding of microscopic perineural invasion. Definitive therapy consisted of radiotherapy alone after lesion biopsy (3 patients) or surgical excision preceded (2 patients) or followed (30 patients) by radiotherapy. All patients had follow-up for at least 1 year, 13 patients (37%) had follow-up for at least 5 years. Results: The 5-year local control rate was 78%. The 5-year local control rate for the few patients treated with radiotherapy alone was statistically similar to that for patients treated with surgery and radiotherapy (100% vs. 77%, p = 0.4). Multivariate analysis for factors affecting local control included sex, histology, age, treatment group, clinical T stage, initial histologic differentiation, and previously untreated vs. recurrent tumors, none of which was found to be significant. Conclusions: Both surgery plus radiotherapy and radiotherapy alone provide a relatively high rate of local control for patients with incidentally discovered perineural invasion secondary to skin cancer

    Granulocytic sarcoma is an extramedullary solid tumour consisting of myelogenous leukaemic blast cells, usually seen in acute myeloid leukaemia and less commonly in patients with chronic myeloid leukaemia or myeloproliferative disorders. Blast cells have a predilection for periosteal and perineural regions and rarely precede evidence of systemic disease. We present two patients, aleukaemic on peripheral blood counts, both at presentation and during subsequent treatment. We present the MRI features of this rare but important condition. (orig.)

    Examination of the effectiveness of perineural dexamethasone administered in very low and low doses on ropivacaine brachial plexus block duration. Retrospective evaluation of brachial plexus block duration in a large cohort of patients receiving peripheral nerve blocks with and without perineural dexamethasone in a prospectively collected quality assurance database. A single academic medical center. A total of 1,942 brachial plexus blocks placed over a 16-month period were reviewed. Demographics, nerve block location, and perineural dexamethasone utilization and dose were examined in relation to block duration. Perineural dexamethasone was examined as none (0 mg), very low dose (2 mg or less), and low dose (greater than 2 mg to 4 mg). Continuous catheter techniques, local anesthetics other than ropivacaine, and block locations with fewer than 15 subjects were excluded. Associations between block duration and predictors of interest were examined using multivariable regression models. A subgroup analysis of the impact of receiving dexamethasone on block duration within each block type was also conducted using a univariate linear regression approach. A total of 1,027 subjects were evaluated. More than 90% of brachial plexus blocks contained perineural dexamethasone (≤4 mg), with a median dose of 2 mg. Increased block duration was associated with receiving any dose of perineural dexamethasone (P block duration did not differ with very low- or low-dose perineural dexamethasone after controlling for other factors (P = 0.420). Perineural dexamethasone prolonged block duration compared with ropivacaine alone; however, duration was not greater with low-dose compared with very low-dose perineural dexamethasone. © 2017 American Academy of Pain Medicine.

    2000-01-01

    Purpose: To review treatment and outcomes in 62 patients with clinical and/or gross evidence of perineural invasion from skin cancer of the head and neck. Methods and Materials: Sixty-two patients received radiotherapy at the University of Florida as part or all of their treatment between January 1965 and April 1995. All patients had clinical signs and symptoms of perineural involvement and/or documentation of tumor extending to grossly involve nerve(s). Twenty-one patients underwent therapy for previously untreated lesions, including 12 who received radiotherapy alone and nine who had surgery with postoperative radiotherapy. Forty-one patients underwent therapy for recurrent lesions, including 18 treated with radiotherapy alone and 23 who received preoperative or postoperative radiotherapy. Results: Factors on multivariate analysis that predicted local control included patient age, previously untreated vs. recurrent lesions, presence of clinical symptoms, and extent of radiotherapy fields. Recurrence patterns were predominantly local; 26 of 31 patients (84%) who developed local recurrence after treatment had recurrent cancer limited to the primary site. Conclusions: Many patients with skin cancer and symptomatic perineural invasion have disease that is incompletely resectable. Approximately half these patients will be cured with aggressive irradiation alone or combined with surgery. Age, prior treatment, and clinical symptoms influence the likelihood of cure

    Queensland, Australia, has the highest rates of cutaneous squamous cell carcinoma (SCC). Perineural invasion (PNI) is associated with reduced local control and survival. A retrospective review of a prospective database of patients with clinical PNI from cutaneous SCC of the head and neck (SCCHN) treated with surgery and postoperative radiotherapy (PORT) between 2000 and 2011 and a minimum of 24 months follow-up. Patients were excluded if immunosuppressed, had non-SCC histology, or were treated palliatively. Fifty patients (mean age, 60 years) with median follow-up of 50 months were included in this study. A total of 54.8% of known primary tumors had incidental PNI. Ten percent had nodal disease at presentation. MRI neurogram was positive in 95.8%. Recurrence-free survival (RFS) at 5-years was 62%. Five-year disease-specific survival (DSS) and overall survival (OS) were 75% and 64%, respectively. There were no perioperative deaths.

    Full Text Available Abstract Background Perineural invasion is a common path for cholangiocarcinoma (CCA metastasis, and it is highly correlated with postoperative recurrence and poor prognosis. It is often an early event in a disease that is commonly diagnosed in advanced stages, and thus it could offer a timely therapeutic and diagnostic target if better understood. This article systematically reviews the progress of CCA neural invasion-related molecules. Methods Studies were identified by searching MEDLINE and PubMed databases for articles from January 1990 to December 2009, using the keywords "cholangiocarcinoma," "perineural invasion," "nerve growth factor"(NGF, "neural cell adhesion molecule" (NCAM, "matrix metalloproteinase"(MMP, "neurotransmitter," "acetylcholine" (Ach, and "transforming growth factor" (TGF." Additional papers and book chapters were identified by a manual search of references from the key articles. Results From above we found that the molecules NGF, NCAM, MMP, Ach and TGF may have prognostic significance in, and offer clues to the mechanism of CCA neural invasion. Conclusions Cholangiocarcinoma's increasing worldwide incidence is especially poignant in view of both the lacking effective therapies, and the fact that it is commonly diagnosed in advanced stages. As CCA neural invasion often appears early, more complete characterization of its molecular pathology could lead to the identification of targets for the diagnosis and therapy of this devastating malignancy.

    Perineural invasion resulting in leptomeningeal carcinomatosis is a rare, but well-recognized phenomenon in head and neck carcinomas. We report the rare case of a patient with a squamous cell carcinoma of the lip resulting in leptomeningeal carcinomatosis and review the relevant published work. A 51-year-old man presented with progressive facial paraesthesia after treatment for a recurrent squamous cell carcinoma of the lower lip. Cavernous sinus involvement was confirmed on MRI and he received stereotactic radiotherapy. He subsequently developed progressive lower limb neurological signs. An MRI showed multiple enhancing leptomeningeal nodules in the cervical and lumbar spine consistent with leptomeningeal carcinomatosis. Whole spine radiotherapy and dexametha-sone resulted in short-term stabilization of symptoms only and he rapidly succumbed to progressive neurological disease. To our knowledge, this is the first published report of a squamous cell carcinoma of the lip resulting in leptomeningeal disease of the cauda equina. It illustrates the potential aggressive natural history of squamous cell carcinomas with perineural invasion Copyright (2006) Blackwell Publishing Asia Pty Ltd

  9. Does dexamethasone have a perineural mechanism of action?

    DEFF Research Database (Denmark)

    Jæger, P; Grevstad, Jens Ulrik; Koscielniak-Nielsen, Z J

    2016-01-01

    BACKGROUND: Dexamethasone prolongs block duration. Whether this is achieved via a peripheral or a central mechanism of action is unknown. We hypothesized that perineural dexamethasone added as an adjuvant to ropivacaine prolongs block duration compared with ropivacaine alone, by a locally mediated...... effect when controlled for a systemic action. METHODS: We performed a paired, blinded, randomized trial, including healthy men. All subjects received bilateral blocks of the saphenous nerve with ropivacaine 0.5%, 20 ml mixed with dexamethasone 2 mg in one leg and saline in the other, according...

    Background Intracavernous (IC) injection of stem cells has been shown to ameliorate cavernous-nerve (CN) injury-induced erectile dysfunction (ED). However, the mechanisms of action of adipose-derived stem cells (ADSC) remain unclear. Objectives To investigate the mechanism of action and fate of IC injected ADSC in a rat model of CN crush injury. Design, setting, and participants Sprague-Dawley rats (n = 110) were randomly divided into five groups. Thirty-five rats underwent sham surgery and IC injection of ADSC (n = 25) or vehicle (n = 10). Another 75 rats underwent bilateral CN crush injury and were treated with vehicle or ADSC injected either IC or in the dorsal penile perineural space. At 1, 3, 7 (n = 5), and 28 d (n = 10) postsurgery, penile tissues and major pelvic ganglia (MPG) were harvested for histology. ADSC were labeled with 5-ethynyl-2-deoxyuridine (EdU) before treatment. Rats in the 28-d groups were examined for erectile function prior to tissue harvest. Measurements IC pressure recording on CN electrostimulation, immunohistochemistry of the penis and the MPG, and number of EdU-positive (EdU+) cells in the injection site and the MPG. Results and limitations IC, but not perineural, injection of ADSC resulted in significantly improved erectile function. Significantly more EdU+ ADSC appeared in the MPG of animals with CN injury and IC injection of ADSC compared with those injected perineurally and those in the sham group. One day after crush injury, stromal cell-derived factor-1 (SDF-1) was upregulated in the MPG, providing an incentive for ADSC recruitment toward the MPG. Neuroregeneration was observed in the group that underwent IC injection of ADSC, and IC ADSC treatment had beneficial effects on the smooth muscle/collagen ratio in the corpus cavernosum. Conclusions CN injury upregulates SDF-1 expression in the MPG and thereby attracts intracavernously injected ADSC. At the MPG, ADSC exert neuroregenerative effects on the cell bodies of injured nerves

    Purpose: The criteria for administration of adjuvant radiation therapy (RT) in oral cavity squamous cell carcinoma (OSCC) remain controversial, and it is unclear whether patients with pT1-3N0 disease benefit from adjuvant radiation in the presence of free margins and perineural invasion. The goal of this report was to determine whether this group would benefit from adjuvant radiation therapy in terms of 5-year local control rate and overall survival rate. Methods and Materials: We retrospectively reviewed our case records from January 1996 to May 2005. In all, 460 pT1-3N0 OSCC patients had tumor-free margins, of whom 68 had perineural invasion. Postoperative adjuvant RT was performed in patients with pT4 tumors, positive lymph nodes, or close margins (≤4 mm). In addition, selected OSCC patients with large pT3 tumors or perineural invasion received postoperative adjuvant RT. Local control and overall survival rates were plotted by Kaplan-Meier analysis. Results: There were no significant differences in 5-year local control (p 0.1936) and overall survival (p = 0.5580) rates between patients with perineural invasion compared with those without. Among patients with perineural invasion, the addition of adjuvant radiotherapy did not significantly alter the 5-year local control rate (p = 0.3170) or the overall survival rate (p = 0.0935). Conclusion: Altogether, these data seem to indicate that radical surgical resection alone should be considered a sufficient treatment for OSCC patients with pT1-3N0 disease, even in the presence of perineural invasion

    A 55-year-old man had a five-day history of “pins and needles” sensation on the left chin. Examination showed decreased pinprick sensation on the territory of the left mandibular branch of the trigeminal nerve. Brain magnetic resonance imaging (MRI) with gadolinium showed enhancement involving the left mandibular branch. Computed tomography (CT) of the chest, abdomen, and pelvis showed a left kidney mass diagnosed as renal carcinoma following nephrectomy. The “numb-chin” syndrome heralds or accompanies systemic malignancies. Trigeminal perineural spread has been well-documented in head and neck neoplasms, however, to our knowledge, it has not been reported in renal neoplasms. (author)

    A 15-year-old healthy boy developed acute, rapidly progressing visual loss in left eye following herpes zoster dermatitis, with a combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO), along with optic perineuritis. Laboratory tests were negative. Despite an empirical, intensive antiviral treatment with systemic corticosteroids, and vision could not be restored in the affected eye. Herpes zoster dermatitis, in an immunocompetent individual, may be associated with a combined CRAO and CRVO along with optic perineuritis, leading to profound visual loss.

    The high contrast resolution and absent ionizing radiation of interventional magnetic resonance imaging (MRI) can be advantageous for paravertebral sympathetic nerve plexus injections. We assessed the feasibility and technical performance of MRI-guided paravertebral sympathetic injections utilizing augmented reality navigation and 1.5 T MRI scanner. A total of 23 bilateral injections of the thoracic (8/23, 35%), lumbar (8/23, 35%), and hypogastric (7/23, 30%) paravertebral sympathetic plexus were prospectively planned in twelve human cadavers using a 1.5 Tesla (T) MRI scanner and augmented reality navigation system. MRI-conditional needles were used. Gadolinium-DTPA-enhanced saline was injected. Outcome variables included the number of control magnetic resonance images, target error of the needle tip, punctures of critical nontarget structures, distribution of the injected fluid, and procedure length. Augmented-reality navigated MRI guidance at 1.5 T provided detailed anatomical visualization for successful targeting of the paravertebral space, needle placement, and perineural paravertebral injections in 46 of 46 targets (100%). A mean of 2 images (range, 1-5 images) were required to control needle placement. Changes of the needle trajectory occurred in 9 of 46 targets (20%) and changes of needle advancement occurred in 6 of 46 targets (13%), which were statistically not related to spinal regions (P = 0.728 and P = 0.86, respectively) and cadaver sizes (P = 0.893 and P = 0.859, respectively). The mean error of the needle tip was 3.9±1.7 mm. There were no punctures of critical nontarget structures. The mean procedure length was 33±12 min. 1.5 T augmented reality-navigated interventional MRI can provide accurate imaging guidance for perineural injections of the thoracic, lumbar, and hypogastric sympathetic plexus.

    Perineural spread of tumour cells along cranial nerves is a severe complication of primary cutaneous squamous cell carcinomas of the head and neck region. While surgical excision of the tumour is the treatment of choice, removal of all the tumour is often complicated by the neural location and recurrence is frequent. Non-invasive immune treatments such as checkpoint inhibitor blockade may be useful in this set of tumours although little is understood about the immune response to perineural spread of squamous cell carcinomas. Immunohistochemistry studies suggest that perineural tumour contains a lymphocyte infiltrate but it is difficult to quantitate the different proportions of immune cell subsets and expression of checkpoint molecules such as PD-1, Tim-3 and CTLA-4. Using flow cytometry of excised perineural tumour tissue, we show that a T cell infiltrate is prominent in addition to less frequent B cell, NK cell and NKT cell infiltrates. CD8 T cells are more frequent than other T cells in the tumour tissue. Amongst CD8 T cells, the frequency of Tim-3, CTLA-4 and PD-1 expressing cells was significantly greater in the tumour relative to the blood, a pattern that was repeated for Tim-3, CTLA-4 and PD-1 amongst non-CD8 T cells. Using immunohistochemistry, PD-1 and PD-L1-expression could be detected in close proximity amongst perineural tumour tissue. The data suggest that perineural SCC contains a mixture of immune cells with a predominant T cell infiltrate containing CD8 T cells. Elevated frequencies of tumour-associated Tim-3+, CTLA-4+ and PD-1+ CD8 T cells suggests that a subset of patients may benefit from local antibody blockade of these checkpoint inhibitors.

    Full Text Available The clinical and histopathological effects of two alcoholic neurolytics were studied in horses. Normal horses were shod with a designed shoe adaptted with 5 screws to produce solar pain. After gait and lameness score analysis, the palmar nerve of 5 horses was injected with 5 ml of 0,75% benzyl alcohol (Group A and 5 horses were injected with 5 ml of absolute ethyl alcohol (Group B. The animals were submitted to regular lameness evaluation and solar sensibility tests during next six months. The solar sensitivity returned 5 months latter in the group injected with benzyl alcohol 0,75%, while in the group injected with absolute ethyl alcohol, the sole was still desensitized 6 months latter. The histopathological findings showed that the nerve injected with benzyl alcohol 0,75%, resulted in axonotmesis, characterized by axonal nerve degeneration, with possibilities for the nerve conduction recovery. The perineural injection of ethyl alcohol absolute, resulted in neurotmesis with difficult nerve regeneration. It was concluded that chemical neurolysis with alcohol is an option for temporary or permanent nerve blocks in horses.

    Purpose: To determine if the presence of perineural invasion (PNI) predicts biochemical recurrence in patients who underwent low-dose-rate brachytherapy for the treatment of localized prostate cancer. Methods and Materials: A retrospective case control matching study was performed. The records of 651 patients treated with brachytherapy between 1996 and 2003 were reviewed. Sixty-three of these patients developed biochemical failure. These sixty-three patients were then matched in a one-to-one ratio to patients without biochemical failure, controlling for biopsy Gleason score, clinical stage, initial prostate-specific antigen, age, and the use of androgen deprivation. The pathology of the entire cohort was then reviewed for evidence of perineural invasion on initial prostate biopsy specimens. The biochemical relapse free survival rates for these two groups were compared. Results: Cases and controls were well matched, and there were no significant differences between the two groups in age, Gleason grade, clinical stage, initial prostate-specific antigen, and the use of androgen deprivation. PNI was found in 19 (17%) patients. There was no significant difference in the rates of PNI between cases and controls, 19.6% and 14.3% respectively (p 0.45). PNI did not correlate with biochemical relapse free survival (p 0.40). Conclusion: Perineural invasion is not a significant predictor of biochemical recurrence in patients undergoing brachytherapy for prostate cancer

    Perineural spread (PNS) of cutaneous squamous cell carcinoma of the head and neck (SCCHN) can be associated with poor outcomes. Disease understanding and awareness is limited leading to delayed diagnosis and treatment. The purpose of this study was to identify epidemiological features of patients with PNS of cutaneous SCCHN. Tumor characteristics and demographics of patients with PNS of cutaneous SCCHN managed through a single institution were collected between 1998 and 2013. One hundred twenty patients were included in this study. The majority had a history of skin cancer (85.8%). The median time from primary tumor treatment to PNS symptom onset was 16 months (range, 1-86 months). A total of 34.2% had no perineural invasion (PNI) detected in the primary, and 22.5% had no known primary tumor. Only 5.8% of the patients had nodal involvement at presentation. Patients can present with PNS from cutaneous SCCHN with no known primary tumor or with primary tumors without PNI. The majority of patients presented without regional nodal involvement. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1416-1420, 2016. © 2016 Wiley Periodicals, Inc.

    Understanding the natural history of diseases enables the clinician to better diagnose and treat their patients. Perineural spread of head and neck cancers are poorly understood and often diagnosis is delayed resulting in poorer outcomes and more debilitating treatments. This article reviews a large personal series of head and neck malignancy presenting with perineural spread along almost exclusively the trigeminal and/or facial nerves. A detailed analysis of squamous cell carcinoma of cutaneous origin is presented including an analysis of likely primaries, which most often have occurred months to years prior. The importance of early detection is reinforced by the highly significant (p < 0.0001) differences in disease specific survival, which occur, depending on how far along a cranial nerve the disease has been allowed to spread.

    Full Text Available Introduction: Contemporary literature indicates precaution over the perioperative use of non-steroidal anti-inflammatory drugs, since they can potentially increase perioperative blood loss related to their mechanism of action. The aim of this study was to assess the influence of non-steroidal anti-inflammatory drugs on perioperative blood loss undergoing hip arthroplasty and its correlation with general and regional anesthesia.Methods: This prospective study included 120 patients who had undergone elective unilateral total hip arthroplasty. Patients were allocated into four groups. Groups 1 and 2 were pretreated with diclofenac and operated in general and regional anesthesia. Group 3 and 4 weren’t pretreated with any non-steroidal anti-inflammatory drug and were, as well, operated in general and regional anesthesia. Diclofenac was administered orally two times a day 75 mg (total 150 mg and also as intramuscular injection (75 mg preoperatively and 12 hours later on a day of surgery.Results: The perioperative blood loss in the rst 24 hours showed an increase of 29.4% in the diclofenac group operated in general anesthesia and increase of 26.8% in patients operated in regional anesthesia (P < 0.05 compared to control group. Statistical data evaluation of patients operated in general anesthesia compared to regional anesthesia, the overall blood loss in the rst 24 h after surgery, showed an increase of 6.4% in the diclofenac group and increase of 3.6% in placebo group. This was not statistically significant.Conclusion: Pretreatment with non-steroidal anti-inflammatory drugs (diclofenac before elective unilateral total hip arthroplasty increases the perioperative blood loss signficantly. Early discontinuation of non-selective non-steroidal anti-inflammatory drugs is advised.

    Nonmelanoma skin cancer (NMSC) with perineural invasion (PNI) is most commonly seen in cutaneous squamous cell carcinoma of the head and neck (SCCHN). The cranial nerves are a conduit for skin cancer to reach the brainstem. The histopathological features of 51 tissue specimens from 49 patients with cutaneous SCCHN and clinical PNI were assessed with consecutive transverse and longitudinal sections. No skip lesions were identified. Tumor spread was contiguous in all specimens. No tumor spread into the perineural space from surrounding or adjacent tumor was seen. Proximal large cranial nerves showed epineural involvement in 3.9% in areas with large tumor bulk, extensive PNI, and intraneural invasion. Perineural tumor spread in cutaneous SCCHN was contiguous and no skip lesions were evident in nerve specimens assessed in this series. Spread beyond cranial nerve perineurium was uncommon, reflecting its multilayer barrier function at this level. These findings may have treatment implications. © 2013 Wiley Periodicals, Inc.

  5. Reexcision Perineural Invasion and Epithelial Sheath Neuroma Possibly on a Spectrum of Postinjury Reactive Hyperplasia Mediated by IL-6.

    Epithelial sheath neuroma is a rarely recognized but established entity in the medical literature. First described in 2000 by Requena et al, there have only been 7 published cases to date, mostly in female patients and presenting as symptomatic solitary lesions on the back without a known history of trauma. In 2006, Beer et al described and reviewed a dozen cases in which epithelial sheath neuroma-like features were seen in the advent of a surgical procedure, which was termed "re-excision perineural invasion" and attributed to possible eccrine duct implantation during surgery. Our case is a 66-year-old male patient who underwent an excision of a melanocytic neoplasm in which a reactive epithelial sheath neuroma was incidentally discovered in the excision specimen, adjacent to the biopsy site cicatrix. Histologically, there was benign cutaneous nerve hyperplasia with a proliferation of squamous epithelium in intimate apposition to the nerve bundles in the superficial dermis. We postulate that the process active in the formation of re-excision perineural invasion is the same as in epithelial sheath neuroma and that minor trauma not appreciable on histologic examination is responsible in the latter entity. We performed IL-6 staining and documented that IL-6 was upregulated at the interface of the nerve and reactive epithelium, but was absent in nerves distant from the site of surgery, suggesting that IL-6 may be essential to the lesion's development. The recognition of reactive epithelial sheath neuroma including the subcategory of re-excision perineural invasion is crucial for the dermatopathologist to prevent mislabeling this reactive entity as a perineural squamous cell carcinoma, which has clinical consequences for the patient such as wider re-excision and radiation treatment. Additionally, we have identified a potential pathophysiologic basis for this lesion.

    The surgical management of perineural spread of head and neck cancers has become an integral part in the contemporary treatment of this pathology. We now understand that tumour spreads within the epineurium and in a continuous fashion. We also can rely on the accuracy of magnetic resonance neurography in detecting and defining the extent of disease. With modern skull base techniques and a greater understanding of the anatomy in this region, specific operations can be designed to help eradicate disease. We review the current approaches and techniques used that enable us to better obtain tumour free margins and hence improve survival.

    Sepsis and postoperative infection can occur as a result of unsafe practices in the administration of propofol and other injectable medications. Investigations of infection outbreaks have revealed the causes to be related to bacterial growth in or contamination of propofol and unsafe medication practices, including reuse of syringes on multiple patients, use of single-use medication vials for multiple patients, and failure to practice aseptic technique and adhere to infection control practices. Surveys conducted by AORN and other researchers have provided additional information on perioperative practices related to injectable medications. In 2009, the US Food and Drug Administration and the Centers for Disease Control and Prevention convened a group of clinicians to gain a better understanding of the issues related to infection outbreaks and injectable medications. The meeting participants proposed collecting data to persuade clinicians to adopt new practices, developing guiding principles for propofol use, and describing propofol-specific, site-specific, and practitioner-specific injection techniques. AORN provides resources to help perioperative nurses reduce the incidence of postoperative infection related to medication administration. Copyright © 2012 AORN, Inc. Published by Elsevier Inc.

    This article by the Perineural Invasion (PNI) Registry Group aims to clarify clinical and histopathological ambiguities surrounding PNI in non-melanoma skin cancer (NMSC). PNI is reportedly present in approximately 2-6% of cases of NMSC and is associated with greater rates of morbidity and mortality. The distinction between clinical PNI and incidental PNI is somewhat unclear, especially in regard to management and prognosis. One important objective of the PNI Registry is to develop a standardised method of classifying perineural invasion. Hence, in this article we propose a definition for PNI and for its sub-classification. This article also provides a critical analysis of the current literature on the treatment of incidental PNI by evaluating the key cohort studies that have investigated the use of surgery or radiotherapy in the management of incidental PNI. At present, there are no universal clinical guidelines that specify the acceptable treatment of NMSC exhibiting incidental PNI. Consequently, patients often receive surgery with varying wider margins, or radiotherapy despite the limited evidence substantiating such management options. It is evident from the existing literature that current opinion is divided over the benefit of adjuvant radiotherapy. Certain prognostic factors have been proposed, such as the size and depth of tumour invasion, nerve diameter, the presence of multifocal PNI and the type of tumour. The PNI Registry is a web-based registry that has been developed to assist in attaining further data pertaining to incidental PNI in NMSC. It is envisaged that this information will provide the foundation for identifying and defining best practice in managing incidental PNI. © 2013 The Australasian College of Dermatologists.

This study aimed to investigate the perioperative analgesic effect of a buprenorphine transdermal patch in patients who underwent hallux valgus surgery.Patients and methods: A total of 90 patients were randomly divided into the following three groups based on the perioperative analgesic method: flurbiprofen axetil intravenous injection (Group F, oral celecoxib (Group C, and buprenorphine transdermal delivery system (BTDS (Group BTDS. The pain status, degree of satisfaction, adverse effects, and administration of tramadol hydrochloride for uncontrolled pain were recorded on the night before surgery, postoperative day 1, postoperative day 2, and postoperative day 3.Results: The BTDS could effectively control perioperative pain for patients undergoing ­hallux valgus surgery. The analgesic effect of the BTDS was better than that of oral celecoxib. In addition, statistically significant differences were not observed in the visual analog scale (VAS scores, adverse effects, and rescue analgesia between the patients who received the BTDS and the patients who received the flurbiprofen axetil intravenous injection. However, the degree of patient satisfaction of the BTDS group was significantly higher (P<0.05 than that of the other two groups.Conclusion: The BTDS (a preemptive analgesia regimen could exert an analgesic effect during the perioperative period for patients who had received hallux valgus surgery, and this effect is beneficial for sustaining postoperative physiological and psychological states and promoting functional rehabilitation.

    Full Text Available Perioperative care of the patients with neurological diseases can be challenging. Most important consideration is the management and understanding of pathophysiology of these disorders and evaluation of new neurological changes that occur perioperatively. Perioperative generally refers to 3 phases of surgery: preoperative, intraoperative, and postoperative. We have tried to address few commonly encountered neurological conditions in clinical practice, such as delirium, stroke, epilepsy, myasthenia gravis, and Parkinson disease. In this article, we emphasize on early diagnosis and management strategies of neurological disorders in the perioperative period to minimize morbidity and mortality of patients.

    The aim of this study was to identify the characteristics of perioperative convulsion and to suggest possible correcting strategies. The multi-centre study was conducted prospectively in 22 hospitals across Thailand in 2015. The occurrences of perioperative adverse events were collected. The data was collated by site manager and forwarded to the data management unit. All perioperative convulsion incidences were enrolled and analysed. The consensus was documented for the relevant factors and the corrective strategies. Descriptive statistics were used. From 2,000 incident reports, perioperative convulsions were found in 16 patients. Six episodes (37.5%) were related to anaesthesia, 31.3% to patients, 18.8% to surgery, and 12.5% to systemic processes. The contributing factor was an inexperienced anaesthesia performer (25%), while the corrective strategy was improvements to supervision (43.8%). Incidents of perioperative convulsion were found to be higher than during the last decade. The initiation and maintenance of safe anaesthesia should be continued.

    To discuss the causes of treatment failure in percutaneous spine injections for low back pain or radiculopathy by analyzing patients who have experienced negative treatment effect on their first visit and a positive treatment effect on their second visit. The authors reviewed the cases of 24 patients who visited the pain intervention outpatient department in our hospital due to back pain or radiculopathy. All patients reviewed experienced a negative treatment effect following their first spine injection, but a positive treatment effect following the second injection. The dates of the cases range from June 2003 to May 2004. Two radiologists analyzed the possible causes of the negative treatment effect following the first injection therapies by considering clinical aspects as well as reviewing radiological images. The most common condition was the presence of the change in the level of the second selective nerve root block (n=13). In seven cases, the methods for administering the injections were changed to facet block (n=2), midline epidural block (n=1), selective nerve root block (n=3) and caudal epidural block (n=1). In four cases, there were no changes in the methods for administering the injections nor were there any changes in the level of the selective nerve root block between first and second visit. In those cases, after reviewing spot radiographs performed during injection, we attributed the causes of failure of injection therapy to an inappropriate distribution of drugs. We can improve the effect of percutaneous spine injections for low back pain or radioculopathy by determining the exact level of perineural root block, trying alternative methods, and insuring a good distribution of the injected drugs

    Using qualitative research and a collaborative academic service partnership, we created an innovative 120-hour perioperative nursing summer internship for eight undergraduate nursing students in 2016. Recognizing that perioperative exposure is limited in the traditional baccalaureate program, this unpaid internship served to clarify student perceptions of perioperative nursing care and encourage graduates to meet perioperative workforce demands. We based the theoretical and practical student learning experiences on the AORN Periop 101 learning modules and included faculty-led discussions, student journaling, and onsite precepted clinical activities. Evaluation data revealed that students achieved an enhanced awareness of perioperative nursing, and a majority of the participants expressed a desire to enter the perioperative field after graduation. We suggest that stakeholders continue to strategize ways to maximize educational preparation to address the evolving health care market supply and demand. © AORN, Inc, 2018.

    Full text: Introduction: Chronic spinal pain is an important health issue with serious social and financial consequences. Thus, application of minimal invasive procedures is a popular technique for immediate relief of pain. Objectives and tasks: Our purpose is to present CT guided intraspinal injection of pharmaceutical agents for the relief of persistent pain. Material and methods: Chronic localized or radicular spinal pain may be treated safely and efficiently with injection of various pharmaceutical agents (local anesthetic, opioid analgesic and steroids or combination of these). The possible sites of infiltration include: a) intervertebral joints (facets), b) sacroiliac joints, c)perineural infiltration of the affected nerve roots and d) the epidural space. We will mention the patients choice criteria (combination of clinical symptoms and specific pain evaluation questionnaire) as they are reported in the international bibliography. Finally, we will discuss the repeatability criteria of the method as well as its limitations. Results: CT-guided pharmaceutical agents injection for the relief of persistent spinal pain have an advantage against other methods because of the precision and safety that they offer to the localization and diagnosis of the pain cause. Conclusion: Small complications percentage and satisfactory results have made CT-guided spinal injections a popular technique for chronic back pain relief. In order to apply these techniques the good knowledge of the method, its possibilities and limitations is necessary

    Diluted bee venom (BV) is known to have anti-nociceptive and anti-inflammatory effects. We therefore assessed whether perineural bee venom pretreatment could attenuate the development of neuropathic pain in the spinal nerve ligation injured animal model. Neuropathic pain was surgically induced in 30 male Sprague Dawley rats by ligation of the L5 and L6 spinal nerves, with 10 rats each treated with saline and 0.05 and 0.1 mg BV. Behavioral testing for mechanical, cold, and thermal allodynia was conducted on postoperative days 3 to 29. Three rats in each group and 9 sham operated rats were sacrificed on day 9, and the expression of transient receptor potential vanilloid type 1 (TRPV1), ankyrin type 1 (TRPA1), and melastatin type 8 (TRPM8) receptors in the ipsilateral L5 dorsal root ganglion was analyzed. The perineural administration of BV to the spinal nerves attenuated the development of mechanical, thermal, and cold allodynia, and the BV pretreatment reduced the expression of TRPV1, TRPA1, TRPM8 and c - Fos in the ipsilateral dorsal root ganglion. The current study demonstrates that the perineural pretreatment with diluted bee venom before the induction of spinal nerve ligation significantly suppresses the development of neuropathic pain. Furthermore, this bee venom induced suppression was strongly related with the involvement of transient receptor potential family members.

    Purpose: To determine if perineural invasion (PNI) should be included in addition to prostate-specific antigen (PSA), biopsy Gleason score, and clinical T-stage for risk-stratification of patients with localized prostate cancer. Methods and Materials: We analyzed prostatectomy findings for 1550 patients, from a prospectively collected institutional database, to determine whether PNI was a significant predictor for upgrading of Gleason score or pathologic T3 disease after patients were stratified into low-, intermediate-, and high-risk groups (on the basis of PSA, biopsy Gleason score, and clinical T-stage). Results: For the overall population, PNI was associated with a significantly increased frequency of upgrading and of pathologic T3 disease. After stratification, PNI was still associated with significantly increased odds of pathologic T3 disease within each risk group. In particular, for low-risk patients, there was a markedly increased risk of extraprostatic extension (23% vs. 7%), comparable to that of intermediate-risk patients. Among high-risk patients, PNI was associated with an increased risk of seminal vesicle invasion and lymph node involvement. Furthermore, over 80% of high-risk patients with PNI were noted to have an indication for postoperative radiation. Conclusions: Perineural invasion may be useful for risk-stratification of prostate cancer. Our data suggest that low-risk patients with PNI on biopsy may benefit from treatment typically reserved for those with intermediate-risk disease. In addition, men with high-risk disease and PNI, who are contemplating surgery, should be informed of the high likelihood of having an indication for postoperative radiation therapy

    Since the mid-1960s surgeons have attempted to cure intracranial perineural spread (PNS) of cutaneous malignancies. Untreated patients with trigeminal PNS die from brainstem invasion and leptomeningeal disease. It was understood that resection with clear margins was potentially curative, but early surgical attempts were unsuccessful. The prevailing wisdom considered that this surgery failed to improve the results achieved with radiation therapy alone and was associated with high morbidity. However, with improved imaging, surgical equipment, and better understanding of cavernous sinus (CS) anatomy and access, contemporary surgeons can improve outcomes for this disease. The aim of this paper is to describe a technique to access the interdural compartment of the CS and treat PNS of cutaneous squamous cell carcinoma (cSCC) in the intracranial trigeminal nerve and ganglion. It is based on the experience of the Queensland Skull Base Unit, Australia in managing PNS of cutaneous squamous cell carcinoma of the head and neck (cSCCHN).

    Full Text Available This study aimed to evaluate the evidence available in the literature about the perioperative care provided to women submitted to mastectomy. An integrative review of scientific literature conducted in MEDLINE, CINAHL, LILACS, and SciELO databases, published from 2000 to 2011, using the controlled descriptors: preoperative care; preoperative period; intraoperative care; intraoperative period; postoperative care; postoperative period; perioperative care; perioperative period; and mastectomy. The sample of this review consisted of seven articles. The evidence pointed as perioperative care of mastectomy the pharmacological management of pain in different surgical periods. Despite the difficulty in presenting a consensus of evidence for perioperative care of mastectomy, there was concern on the part of professionals to minimize/prevent pre-, intra- and post-operative pain. Nursing should be aware, both of the update of pharmacological treatments in pain management and the development of future research related to nursing care in the perioperative period of mastectomy.

    Hospital acquired pressure ulcers have a detrimental effect on patient quality of life, morbidity, mortality, and cost to the healthcare industry. Little is known about pressure ulcer prevention in perioperative services. The objectives of this study were to describe perioperative registered nurses (RNs) knowledge, attitudes, behaviors, and barriers about pressure ulcer prevention and to determine if knowledge and the availability of a pressure ulcer staging tool are predictors of pressure ulcer prevention behavior. A cross-sectional descriptive pilot study was conducted. Sixty-two perioperative RNs from 10 acute care hospitals participated. Perioperative nurses believed carrying out pressure ulcer prevention strategies is essential to nursing practice but only two-thirds reported conducting pressure ulcer risk assessment on all patients and daily assessment on at risk patients. Results indicated a knowledge deficit regarding assessment and prevention of pressure ulcers as performance on the PUKT (72%) fell below the recommended score of 90%. Results of binary logistic regression indicated that knowledge as measured by the PUKT and availability of a pressure ulcer staging tool were statistically significant (p=0.03) predictors of pressure ulcer prevention behavior. The initial model without the predictor variables, indicated an overall success rate of correct predictions of 64% which increase to 73% when the predictor variables were added to the initial model. Although perioperative nurses believe that pressure ulcer prevention is important, a knowledge deficit exists and there is a need for pressure ulcer prevention education.

    Pancreaticodudenectomy (PD) is a high-risk, technically demanding operation associated with substantial perioperative morbidity and mortality. This review is intended to evaluate the perioperative outcomes of PD done in a single gastrointestinal surgery unit of a university teaching hospital. A retrospective review of medical records of patients who underwent PD from April 2005 through May 2009 was done. Perioperative morbidity was defined according to the standard of the International Study Group for Pancreatic Fistula (ISGPF). The patient demographics, type of surgery, and perioperative morbidity and mortality were evaluated. The factors associated with increased morbidity were analyzed. Twenty-four patients underwent PD, and there were no perioperative deaths. The overall morbidity was 58%, with a pancreatic fistula rate of 13%. None of the associated parameters, like increasing age, the presence of co-morbidity, preoperative biliary drainage, and duration of surgery, were found to increase the morbidity. These results of PD, though a small case series, are comparable to the international standard. Better outcomes can be achieved even in low- to medium-volume centers in developing countries where a dedicated team with special interest in pancreatic surgery is in place. Although there were no deaths after PD in our series, the morbidity was higher than that observed in other high-volume centers. To decrease the morbidity associated with PD, various factors must be streamlined, among them, the operative technique and the intensive perioperative management of the patient, as well as uniform definition of complications, use of a multidisciplinary approach, and identification of associated risk factors.

Similarly, surgical treatment with Heller myotomy is associated with complications. At our institution, we perform the peroral endoscopic myotomy (POEM in qualified patients. Briefly, POEM involves endoscopic creation of a mid-esophageal submucosal bleb, creation of a submucosal tunnel with the endoscope, and then a distal myotomy, resulting in relaxation of the distal esophagus. The aim of our study is to document perioperative pain and associated pain management for our initial patients undergoing POEM and to review the literature for perioperative complications of this procedure. Therefore, anesthetic and pain management for our initial eleven patients undergoing POEM were reviewed. Patient demographics, pre-POEM pain medication history, perioperative pain medication requirements, and post-POEM pain scores were examined. We found post-POEM pain was usually in the mild–moderate range; a combination of medications was effective (opioids, nonsteroidal anti-inflammatory drugs, acetaminophen. Our literature search revealed a wide frequency range of complications such as pneumoperitoneum and subcutaneous emphysema, with rare serious events such as capnopericardium leading to cardiac arrest. In conclusion, our experience with POEM suggests pain and can be managed adequately with a combination of medications; the procedure appears to be safe and reasonable to perform in an outpatient endoscopy unit.

    This study focuses on investigating habits in perioperative nursing culture, which are often simply accepted and not normally considered or discussed. A hermeneutical approach was chosen as the means of understanding perioperative nurses' experiences of and reflections on operating theatre culture. Focus group discussions were used to collect data, which was analysed using hermeneutical text analysis. The results revealed three main categories of habits present in perioperative nursing culture: habits that promote ethical values (by temporary friendship with patients, showing respect for each other, and spending time on reflection on ethics and caring); habits that hinder progress (by seeing the patient as a surgical case, not acknowledging colleagues, and not talking about ethics); and habits that set the cultural tone (the hidden power structure and achieving more in less time).

    2012-04-01

    Full Text Available Abstract Background We have identified syndecan-2 as a protein potentially involved in perineural invasion of pancreatic adenocarcinoma (PDAC cells. Methods Syndecan-2 (SDC-2 expression was analyzed in human normal pancreas, chronic pancreatitis and PDAC tissues. Functional in vitro assays were carried out to determine its role in invasion, migration and signaling. Results SDC-2 was expressed in the majority of the tested pancreatic cancer cell lines while it was upregulated in nerve-invasive PDAC cell clones. There were 2 distinct expression patterns of SDC-2 in PDAC tissue samples: SDC-2 positivity in the cancer cell cytoplasm and a peritumoral expression. Though SDC-2 silencing (using specific siRNA oligonucleotides did not affect anchorage-dependent growth, it significantly reduced cell motility and invasiveness in the pancreatic cancer cell lines T3M4 and Su8686. On the transcriptional level, migration-and invasion-associated genes were down-regulated following SDC-2 RNAi. Furthermore, SDC-2 silencing reduced K-ras activity, phosphorylation of Src and - further downstream - phosphorylation of ERK2 while levels of the putative SDC-2 signal transducer p120GAP remained unaltered. Conclusion SDC-2 is a novel (perineural invasion-associated gene in PDAC which cooperates with K-ras to induce a more invasive phenotype.

    Hyperglycemia is a common finding in surgical patients during the perioperative period. Factors contributing to poor glycemic control include counterregulatory hormones, hepatic insulin resistance, decreased insulin-stimulated glucose uptake, use of dextrose-containing intravenous fluids, and enteral and parenteral nutrition. Hyperglycemia in the perioperative period is associated with increased morbidity, decreased survival, and increased resource utilization. Optimal glucose management in the perioperative period contributes to reduced morbidity and mortality. To readily identify hyperglycemia, blood glucose monitoring should be instituted for all hospitalized patients. Published by Elsevier Inc.

    This paper aims to explore the assessment of patients with rheumatologic diseases, especially rheumatoid arthritis (RA), before undergoing orthopedic surgery. Perioperative assessment ensures an early diagnosis of the patient's medical condition, overall health, medical co-morbidities, and the assessment of the risk factors associated with the proposed procedures. Perioperative assessment allows for proper postoperative management of complications and of the management of drugs such as disease-modifying anti-rheumatic drugs (DMARD) and anti-platelets, and corticosteroids. The assessment also supports follow up plans, and patient education. Perioperative assessment enables the discussion of the proposed treatment plans and the factors associated with them in each case among the different specialists involved to facilitate an appropriate early decision-making about the assessment and treatment of patients with rheumatologic diseases. It also enables the discussion of both condition and procedure with the patient to ensure a good postoperative care. The article identifies the components of perioperative medical evaluation, discusses perioperative management of co-morbidities and the management of specific clinical problems related to RA, systemic lupus erythematosus, the management of DMARDs, like methotrexate (MTX) and biologic therapies, prophylactic antibiotics, and postoperative follow up, including patient education and rehabilitation PMID:24062860

    We evaluated the systemic and local effects of clonidine as an analgesic adjunct to psoas compartment block (PCB) with levobupivacaine. In a randomized, prospective, double-blind trial, 36 patients requiring hip fracture surgery received PCB and general anesthesia. Patients were randomized into three groups. Each patient received PCB with 0.4 mL\\/kg of levobupivacaine 0.5%. The control group (group L) received IV saline, the systemic clonidine group (group IC) received IV clonidine 1 mug\\/kg, and the peripheral clonidine group (group C) received IV saline and PCB with clonidine 1 microg\\/kg. The interval from time of completion of block injection to first supplementary analgesic administration was longer in group IC compared with group L (mean +\\/- sd, 13.4 +\\/- 6.1 versus 7.3 +\\/- 3.6 h; P = 0.03). There was no difference between group C and group L (10.3 +\\/- 5.9 versus 7.3 +\\/- 3.6 h; P > 0.05). The groups were similar in terms of 24 h cumulative morphine and acetaminophen consumption. There were no significant differences among groups regarding postoperative adverse effects (bradycardia, hypotension, sedation, and nausea). We conclude that IV but not perineural clonidine (1 microg\\/kg) prolongs analgesia after PCB without increasing the incidence of adverse effects.

    Full Text Available Death to most people is a major life event. Nothing in this world prepares us to face and manage the perioperative death although the majority of anesthesiologists will be involved in an intraoperative death during the course of their careers. Whether death on the table was expected or occurred when least expected or may be even later, the anesthesiologist is most likely to be affected emotionally, physically in his personal life, and as well as will have an influence on his professional career. Anesthesiologists as perioperative physicians are likely to experience death on the operating table at some time in their careers. In case of perioperative death, meticulous record keeping including time of occurrence of event and methods and medications used during resuscitation, nature of the problem, and all sequence of events should be adopted to breaking bad news with relatives and blame game should be avoided. The anesthesiologist and the relatives of the patient should also be given emotional support to come out of this untoward event. In this article, we have highlighted the various factors and causes leading on to perioperative death and if in case such an event occurs, what are the protocols to be followed, including medicolegal aspects, giving emotional support to the concerned anesthesiologist, dealing with the relatives of the patient sympathetically, etc. We have also enumerated the various precautions to be taken to prevent perioperative mortality in this article.

    The relationship between preoperative malnutrition and morbi-mortality has been documented for years. Despite the existence of tools that allow its detection, and therefore treat this entity, their introduction into clinical practice is not wide-spread. Both perioperative insulin resistance and hyperglycemia are associated with increased perioperative morbidity and length of hospital stay. The intake of carbohydrate-rich drinks 2-4h prior to surgery reduces insulin resistance. In the immediate postoperative period, the enteral route is safe and well tolerated and its early use reduces hospital stay and postoperative complications compared with parenteral nutritional support. Inmunonutrition has been proven effective to decrease postoperative complications and hospital stay. In view of these data we opted for the adoption of these measures replacing bowel rest and the indiscriminate use of postoperative parenteral nutrition. Copyright © 2013 AEC.

    Throughout many countries, professional bodies rely on yearly self-assessment of competence for ongoing registration; therefore, nursing competence is pivotal to safe clinical practice. Our aim was to describe and compare perioperative nurses' perceptions of competence in four countries, while examining the effect of specialist education and years of experience in the operating room. We conducted a secondary analysis of cross-sectional surveys from four countries including; Australia, Canada, Scotland, and Sweden. The 40-item Perceived Perioperative Competence Scale-Revised (PPCS-R), was used with a total sample of 768 respondents. We used a factorial design to examine the influence of country, years of experience in the operating room and specialist education on nurses' reported perceived perioperative competence. Regardless of country origin, nurses with specialist qualifications reported higher perceived perioperative competence when compared to nurses without specialist education. However, cross-country differences were dependent on nurses' number of years of experience in the operating room. Nurses from Sweden with 6-10 years of experience in the operating room reported lower perceived perioperative competence when compared to Australian nurses. In comparing nurses with > 10 years of experience, Swedish nurses reported significantly lower perceived perioperative competence when compared to nurses from Australia, Canada and Scotland. Researchers need to consider educational level and years of experience in the perioperative context when examining constructs such as competence.

    The Perioperative Nursing Data Set (PNDS) is a nursing language that provides standardized terminology to support perioperative nursing practice. The PNDS represents perioperative nursing knowledge and comprises data elements and definitions that demonstrate the nurse's influence on patient outcomes. Emerging issues and changes in practice associated with the PNDS standardized terminology require ongoing maintenance and periodic in-depth review of its content. Like each new edition of the Perioperative Nursing Data Set, the third edition, published in 2010, underwent content validation by numerous experts in clinical practice, vocabulary development, and informatics. The goal of this most recent edition is to enable the perioperative nurse to use the PNDS in a meaningful manner, as well as to promote standardization of PNDS implementation in practice, both in written documentation and the electronic health record.

    Behavior in response to distressful events during outpatient pediatric surgery can contribute to postoperative maladaptive behaviors, such as temper tantrums, nightmares, bed-wetting, and attention seeking. Currently available perioperative behavioral assessment tools have limited utility in guiding interventions to ameliorate maladaptive behaviors because they cannot be used in real time, are only intended to be used during 1 phase of the experience (e.g., perioperative), or provide only a static assessment of the child (e.g., level of anxiety). A simple, reliable, real-time tool is needed to appropriately identify children and parents whose behaviors in response to distressful events at any point in the perioperative continuum could benefit from timely behavioral intervention. Our specific aims were to (1) refine the Perioperative Adult Child Behavioral Interaction Scale (PACBIS) to improve its reliability in identifying perioperative behaviors and (2) validate the refined PACBIS against several established instruments. The PACBIS was used to assess the perioperative behaviors of 89 children aged 3 to 12 years presenting for adenotonsillectomy and their parents. Assessments using the PACBIS were made during perioperative events likely to prove distressing to children and/or parents (perioperative measurement of blood pressure, induction of anesthesia, and removal of the IV catheter before discharge). Static measurements of perioperative anxiety and behavioral compliance during anesthetic induction were made using the modified Yale Preoperative Anxiety Scale and the Induction Compliance Checklist (ICC). Each event was videotaped for later scoring using the Child-Adult Medical Procedure Interaction Scale-Short Form (CAMPIS-SF) and Observational Scale of Behavioral Distress (OSBD). Interrater reliability using linear weighted kappa (kappa(w)) and multiple validations using Spearman correlation coefficients were analyzed. The PACBIS demonstrated good to excellent

    Music can touch patients deeply and thus transform their anxiety and stress into relaxation and healing. Patients with cancer who undergo surgical procedures are highly stressed. To help alleviate these patients' stress and improve their comfort, perioperative nurses at Memorial Sloan-Kettering Cancer Center (MSKCC), New York, surveyed surgical patients and staff members about introducing a perioperative music program. This article reviews the literature on the use of music in perioperative care settings and describes MSKCC's decision to evaluate and then implement a music program.

    We examined the effects of two perioperative pain management techniques on recovery after laparotomy, as assessed by body weight (BW) and food consumption (FC). All rats received a preoperative intrathecal mixture of morphine plus bupivacaine combined with one of two treatments: (a) injection of slow-release morphine at the end of the surgery or (b) an antiinflammatory drug, interleukin-1 receptor antagonist (IL-1ra), combined with the preoperative mixture. Laparotomy significantly decreased FC and BW. Both analgesic treatments resulted in a faster recovery of FC and BW. This beneficial effect was more pronounced in the group receiving preoperative analgesics combined with IL-1ra. Effective perioperative pain management can improve postoperative recovery. We studied the effects of two preoperative pain management techniques on recovery after laparotomy in rats. Both analgesic treatments resulted in a faster recovery, especially preoperative analgesics combined with interleukin-1 receptor antagonist.

    Full Text Available Pregnant Females require special perioperative consideration as females react differently to treatment from physiologic and behavioural standpoints. Thus a standard perioperative assessment plays a crucial role for successful accomplishment of intraoperative and postoperative phase as well as to resist complications due to pregnancy. Each physiologic system is affected in such a way that may or may not have clinical significance for the surgeons. Thus affect of Pregnancy on cardiovascular, respiratory, gastrointestinal, renal and endocrinal system have been reviewed. Moreover to decrease the hazards to the developing child, impact of surgery/treatment on the fetus has also been discussed. It was concluded that the goal of the perioperative evaluation of pregnant females is to identify its physiological effects on various systems and provide for the best efficacious perioperative treatment algorithm that shall minimize the patient morbidity.

    Perioperative nursing is faced with a staffing crisis attributed in part to minimal numbers of newly graduated nurses choosing a career in this specialty. This article analyzes and applies the concept of value to explore how to maintain an adequate perioperative nursing workforce; recruit newly graduated nurses; and encourage career professional, nurse educator, and student collaboration to generate meaningful value for perioperative nursing. This analysis revealed that value co-creation for perioperative nursing could lead to newly graduated nurses increasingly choosing perioperative nursing as a career, and enjoying satisfying perioperative nursing careers while providing high-quality patient care. © AORN, Inc, 2018.

    Salivary adenoid cystic carcinoma (SACC) is the most frequent salivary gland malignancy with a unique characteristic that has been named perineural invasion (PNI). EMMPRIN is a transmembrane glycoprotein that has been demonstrated to promote PNI in SACC. Slug, one of the most effective promoters of the epithelial-to-mesenchymal transition (EMT), has been found to be associated with PNI in SACC. The aim of the present study was to investigate the roles and relationships of Slug, EMMPRIN, and E-cadherin in the PNI process of SACC. The expression levels of Slug, EMMPRIN, and E-cadherin in 115 primary SACC cases were statistically analyzed by immunohistochemistry. Simultaneously, the SACC cell line SACC-83 was transfected with recombinant plasmids of silencing Slug (si-Slug) and/or silencing EMMPRIN (si-EMMPRIN). The functions of Slug and EMMPRIN in the EMT and PNI process were assessed by reverse transcription PCR (RT-PCR), western blotting, morphological observation, scratch test, migration assay, and in vitro perineural invasion assay. The immunohistochemical statistics revealed that the high expression of Slug and EMMPRIN and the low expression of E-cadherin were significantly associated with the PNI of SACC (P EMMPRIN expression (P EMMPRIN expression were both significantly negatively associated with E-cadherin expression (P EMMPRIN silencing both significantly inhibited EMMPRIN expression but promoted E-cadherin expression in SACC-83 cells (P EMMPRIN, or both induced cell morphology changes and inhibited tumor cell motility and PNI ability in SACC-83 cells (P EMMPRIN and then upregulating E-cadherin in the PNI process of SACC. The present study indicated that Slug and EMMPRIN are potential biomarkers and therapeutic targets for the diagnosis and treatment of PNI in human SACC.

    Despite providing adequate pain relief, a femoral nerve block can induce postoperative muscle weakness after total knee arthoplasty (TKA). Fentanyl has been shown to have peripheral effects but has not been used as a perineural infusate alone after TKA. Sixty patients scheduled for TKA were randomized to one of three blinded groups: a continuous 24 h infusion of either fentanyl 3 μg/ml, ropivacaine 0.1%, or 0.9% normal saline through a femoral nerve sheath catheter at 10 ml/h. The main outcome was maximum voluntary isometric contraction (MVIC) in the quadriceps femoris (knee extension), measured by a handheld dynamometer (Nm/kg). Other variables assessed were preoperative and postoperative visual analog scale (VAS) scores, hamstrings MVIC (knee flexion), active range of motion of the operative knee, distance ambulated, incidence of knee buckling, supplemental morphine usage, postoperative side effects, and serum fentanyl levels. Quadriceps MVIC values were significantly greater in the fentanyl group compared to the group that received ropivacaine (median values, 0.08 vs. 0.03 Nm/kg; p = 0.028). The incidence of postoperative knee buckling upon ambulation was higher in the ropivacaine group compared to the fentanyl group, although not statistically significant (40% vs. 15 %, respectively; p = 0.077). VAS scores while ambulating were not significantly different between the fentanyl group and the ropivacaine group (p = 0.270). Postoperative morphine consumption, nausea and vomiting, and resting VAS scores were similar among the three groups. A continuous perineural infusion of fentanyl produced greater strength retention than ropivacaine post-TKA.

    Diabetes is a common disease in Germany. Due to diabetes-associated end-organ disease, such as large and small vessel disease and neuropathy, diabetic patients require more intense anesthesia care during the perioperative phase. An in-depth and comprehensive medical history focusing on hemodynamic alterations, gastroparesis, neuropathy and stiff joint syndrome is a cornerstone of perioperative care and may affect outcome of diabetes patients more than specific anesthetic medications or the anesthetic procedure. Intraoperative anesthetic care needs to focus on preservation of hemodynamic stability, perioperative infection control and maintenance of glucose homeostasis. Whereas some years ago strict glucose control by aggressive insulin therapy was adamantly advocated, the results of recent studies have put the risk of such therapeutic algorithms into perspective. Therefore, optimized perioperative care of diabetic patients consists of setting a predefined targeted blood glucose level, evidence-based therapeutic approaches to reach that goal and finally adequate and continuous monitoring and amendment of the therapeutic approach if required.

    Anesthesiologists and surgeons are increasingly faced with patients who are under long-term medication. Some of these drugs can interact with anaesthetics or anaesthesia and/or surgical interventions. As a result, patients may experience complications such as bleeding, ischemia, infection or severe circulatory reactions. On the other hand, perioperative discontinuation of medication is often more dangerous. The proportion of outpatient operations has increased dramatically in recent years and will probably continue to increase. Since the implementation of DRGs (pending in Switzerland, introduced in Germany for some time), the patient enters the hospital the day before operation. This means that the referring physician as well as anesthesiologists and surgeons at an early stage must deal with issues of perioperative pharmacotherapy. This review article is about the management of the major drug classes during the perioperative period. In addition to cardiac and centrally acting drugs and drugs that act on hemostasis and the endocrine system, special cases such as immunosuppressants and herbal remedies are mentioned.

  11. Ethics in perioperative practice--patient advocacy.

    Though often difficult, ethical decision making is necessary when caring for surgical patients. Perioperative nurses have to recognize ethical dilemmas and be prepared to take action based on the ethical code outlined in the American Nurses Association's (ANA's) Code of Ethics for Nurses with Interpretive Statements. In this second of a nine-part series that will help perioperative nurses relate the ANA code to their own area of practice, the author looks at the third provision statement, which addresses nurses' position as patient advocates.

    2009-07-01

    Obstructive sleep apnea syndrome (OSA) affects 1%-3% of children. Children with OSA can present for all types of surgical and diagnostic procedures requiring anesthesia, with adenotonsillectomy being the most common surgical treatment for OSA in the pediatric age group. Thus, it is imperative that the anesthesiologist be familiar with the potential anesthetic complications and immediate postoperative problems associated with OSA. The significant implications that the presence of OSA imposes on perioperative care have been recognized by national medical professional societies. The American Academy of Pediatrics published a clinical practice guideline for pediatric OSA in 2002, and cited an increased risk of anesthetic complications, though specific anesthetic issues were not addressed. In 2006, the American Society of Anesthesiologists published a practice guideline for perioperative management of patients with OSA that noted the pediatric-related risk factor of obesity, and the increased perioperative risk associated with adenotonsillectomy in children younger than 3 yr. However, management of OSA in children younger than 1 yr-of-age was excluded from the guideline, as were other issues related specifically to the pediatric patient. Hence, many questions remain regarding the perioperative care of the child with OSA. In this review, we examine the literature on pediatric OSA, discuss its pathophysiology, current treatment options, and recognized approaches to perioperative management of these young and potentially high-risk patients.

    This study was designed to investigate whether dexketoprofen added to perineuraly or subcutaneously alters the effects of levobupivacaine in a rat model of sciatic nerve blockade. Thirty-six rats received unilateral sciatic nerve blocks along with a subcutaneous injection by a blinded investigator assigned at random. Combinations were as follows: Group 1 (sham) perineural and subcutaneous saline; Group 2, perineural levobupivacaine alone and subcutaneous saline; Group 3, perineural levobupivacaine plus dexketoprofen and subcutaneous saline; Group 4, perineural levobupivacaine and subcutaneous dexketoprofen; Group 5, perineural dexketoprofen and subcutaneous saline; and Group 6, perineural saline and subcutaneous dexketoprofen. The levobupivacaine concentration was fixed at 0.05%, and the dose of dexketoprofen was 1 mg kg(-1) . Sensory analgesia was assessed by paw withdrawal latency to a thermal stimulus every 30 min. The unblocked paw served as the control for the assessment of systemic, centrally mediated analgesia. Perineural and subcutaneous dexketoprofen coadministered with perineural levobupivacaine did not enhance the duration of sensory blockade when compared with levobupivacaine alone. There were significant differences between the operative and control paws for time points 30-90 min in the perineural levobupivacaine alone, levobupivacaine + dexketoprofen and subcutaneous dexketoprofen added levobupivacaine group. Significant differences were not determined between the levobupivacaine alone group and dexketoprofen added groups in operative paw. The effects of dexketoprofen are unknown for perineural administration. There is no significant difference between the analgesic effects of peripheral nerve blocks using levobupivacaine alone and plus subcutaneous or perineural dexketoprofen. © 2012 The Authors Fundamental and Clinical Pharmacology © 2012 Société Française de Pharmacologie et de Thérapeutique.

  20. Regional anesthesia techniques for ambulatory orthopedic surgery.

    O'Donnell, Brian D

    2012-02-03

    PURPOSE OF REVIEW: The purpose of this review is to present advances in the use of regional anesthetic techniques in ambulatory orthopedic surgery. New findings regarding the use of both neuraxial anesthesia and peripheral nerve block are discussed. RECENT FINDINGS: Neuraxial anesthesia: The use of short-acting local anesthetic agents such as mepivacaine, 2-chloroprocaine, and articaine permits rapid onset intrathecal anesthesia with early recovery profiles. Advantages and limitations of these agents are discussed.Peripheral nerve block: Peripheral nerve blocks in limb surgery have the potential to transform this patient cohort into a truly ambulatory, self-caring group. Recent trends and evidence regarding the benefits of regional anesthesia techniques are presented.Continuous perineural catheters permit extension of improved perioperative analgesia into the ambulatory home setting. The role and reported safety of continuous catheters are discussed. SUMMARY: In summary, shorter acting, neuraxial, local anesthetic agents, specific to the expected duration of surgery, may provide superior recovery profiles in the ambulatory setting. A trend towards more peripheral and selective nerve blocks exists. The infrapatellar block is a promising technique to provide analgesia following knee arthroscopy. Improved analgesia seen in the perioperative period can be safely and effectively extended to the postoperative period with the use of perineural catheters.

    To explore and explain how nurses minimise risk in the perioperative setting. Perioperative nurses care for patients who are having surgery or other invasive explorative procedures. Perioperative care is increasingly focused on how to improve patient safety. Safety and risk management is a global priority for health services in reducing risk. Many studies have explored safety within the healthcare settings. However, little is known about how nurses minimise risk in the perioperative setting. Classic grounded theory. Ethical approval was granted for all aspects of the study. Thirty-seven nurses working in 11 different perioperative settings in Ireland were interviewed and 33 hr of nonparticipant observation was undertaken. Concurrent data collection and analysis was undertaken using theoretical sampling. Constant comparative method, coding and memoing and were used to analyse the data. Participants' main concern was how to minimise risk. Participants resolved this through engaging in anticipatory vigilance (core category). This strategy consisted of orchestrating, routinising and momentary adapting. Understanding the strategies of anticipatory vigilance extends and provides an in-depth explanation of how nurses' behaviour ensures that risk is minimised in a complex high-risk perioperative setting. This is the first theory situated in the perioperative area for nurses. This theory provides a guide and understanding for nurses working in the perioperative setting on how to minimise risk. It makes perioperative nursing visible enabling positive patient outcomes. This research suggests the need for training and education in maintaining safety and minimising risk in the perioperative setting. © 2017 John Wiley & Sons Ltd.

    The adoption of an electronic health record (EHR) is mandated under current health care legislation reform. The EHR provides data that are patient centered and improves patient safety. There are limited data; however, regarding the attitudes of perioperative nurses toward the use of the EHR. The purpose of this project was to identify perioperative nurses' attitudes toward the use of the EHR. Quantitative descriptive survey was used to determine attitudes toward the electronic health record. Perioperative nurses in a southeastern health system completed an online survey to determine their attitudes toward the EHR in providing patient care. Overall, respondents felt the EHR was beneficial, did not add to the workload, improved documentation, and would not eliminate any nursing jobs. Nursing acceptance and the utilization of the EHR are necessary for the successful integration of an EHR and to support the goal of patient-centered care. Identification of attitudes and potential barriers of perioperative nurses in using the EHR will improve patient safety, communication, reduce costs, and empower those who implement an EHR.

    In the perioperative period, anesthesiologists and postanesthesia care unit (PACU) nurses routinely prepare and administer small-volume IV injections, yet the accuracy of delivered medication volumes in this setting has not been described. In this ex vivo study, we sought to characterize the degree to which small-volume injections (≤0.5 mL) deviated from the intended injection volumes among a group of pediatric anesthesiologists and pediatric postanesthesia care unit (PACU) nurses. We hypothesized that as the intended injection volumes decreased, the deviation from those intended injection volumes would increase. Ten attending pediatric anesthesiologists and 10 pediatric PACU nurses each performed a series of 10 injections into a simulated patient IV setup. Practitioners used separate 1-mL tuberculin syringes with removable 18-gauge needles (Becton-Dickinson & Company, Franklin Lakes, NJ) to aspirate 5 different volumes (0.025, 0.05, 0.1, 0.25, and 0.5 mL) of 0.25 mM Lucifer Yellow (LY) fluorescent dye constituted in saline (Sigma Aldrich, St. Louis, MO) from a rubber-stoppered vial. Each participant then injected the specified volume of LY fluorescent dye via a 3-way stopcock into IV tubing with free-flowing 0.9% sodium chloride (10 mL/min). The injected volume of LY fluorescent dye and 0.9% sodium chloride then drained into a collection vial for laboratory analysis. Microplate fluorescence wavelength detection (Infinite M1000; Tecan, Mannedorf, Switzerland) was used to measure the fluorescence of the collected fluid. Administered injection volumes were calculated based on the fluorescence of the collected fluid using a calibration curve of known LY volumes and associated fluorescence.To determine whether deviation of the administered volumes from the intended injection volumes increased at lower injection volumes, we compared the proportional injection volume error (loge [administered volume/intended volume]) for each of the 5 injection volumes using a linear

  7. Hip Resurfacing Arthroplasty and Perioperative Blood Testing

    Directory of Open Access Journals (Sweden)

    Andrew Cook

    2014-01-01

    Full Text Available It is standard practice in many institutions to routinely perform preoperative and postoperative haemoglobin level testing in association with hip joint arthroplasty procedures. It is our observation, however, that blood transfusion after uncomplicated primary hip arthroplasty in healthy patients is uncommon and that the decision to proceed with blood transfusion is typically made on clinical grounds. We therefore question the necessity and clinical value of routine perioperative blood testing about the time of hip resurfacing arthroplasty. We present analysis of perioperative blood tests and transfusion rates in 107 patients undertaking unilateral hybrid hip resurfacing arthroplasty by the senior author at a single institution over a three-year period. We conclude that routine perioperative testing of haemoglobin levels for hip resurfacing arthroplasty procedures does not assist in clinical management. We recommend that postoperative blood testing only be considered should the patient demonstrate clinical signs of symptomatic anaemia or if particular clinical circumstances necessitate.

    Nutritional status and dietary intake are increasingly recognized as essential areas in esophageal cancer management. Nutritional management of esophageal cancer is a continuously evolving field and comprises an interesting area for scientific research. Areas covered: This review encompasses the current literature on nutrition in the pre-operative, peri-operative, and post-operative phases of esophageal cancer. Both established interventions and potential novel targets for nutritional management are discussed. Expert commentary: To ensure an optimal pre-operative status and to reduce peri-operative complications, it is key to assess nutritional status in all pre-operative esophageal cancer patients and to apply nutritional interventions accordingly. Since esophagectomy results in a permanent anatomical change, a special focus on nutritional strategies is needed in the post-operative phase, including early initiation of enteral feeding, nutritional interventions for post-operative complications, and attention to long-term nutritional intake and status. Nutritional aspects of pre-optimization and peri-operative management should be incorporated in novel Enhanced Recovery After Surgery programs for esophageal cancer.

    Results: All perineural injections resulted in injection pressures below 40 kPa. In contrast, intraneural injections resulted in significantly higher peak pressures (P 140 k Pa. Conclusion: High injection pressure (>140 kPa predicts intraneural injection and consequential neurologic deficit. As long as the injection pressure is low, injection into poorly compliant tissue can be avoided and neurological complication can be prevented.

    Service dogs are critical for the independence of individuals with disabilities because they assist with daily living activities and help these individuals navigate society. Perioperative nurses need a working knowledge of disability laws pertaining to service dogs to provide patient-centered care for individuals using service dogs. This article provides information on the Americans With Disabilities Act regulations regarding service dogs, makes recommendations for the care of patients with service dogs across the perioperative continuum, and offers policy directives to ensure that safe, high-quality care is delivered to patients using service dogs.

    The aim of this study was to translate, culturally adapt and validate the TRUST questionnaire in a Greek perioperative setting. The TRUST questionnaire assesses the relationship between trust and performance. The study assessed the levels of trust and performance in the surgery and anaesthesiology department during a very stressful period for Greece (economic crisis) and offered a user friendly and robust assessment tool. The study concludes that the Greek version of the TRUST questionnaire is a reliable and valid instrument for measuring team performance among Greek perioperative teams.

    2015-01-01

    Purpose Of Review Optimizing hemostasis with antifibrinolytics is becoming a common surgical practice. Large clinical studies have demonstrated efficacy and safety of tranexamic acid (TXA) in the trauma population to reduce blood loss and transfusions. Its use in patients without preexisting coagulopathies is debated, as thromboembolic events are a concern. In this review, perioperative administration of TXA is examined in non-trauma surgical populations. Additionally, risk of thromboembolism, dosing regimens, and timing of dosing are assessed. Recent Findings Perioperative use of tranexamic acid is associated with reduced blood loss and transfusions. Thromboembolic effects do not appear to be increased. However, optimal dosing and timing of TXA administration is still under investigation for non-trauma surgical populations. Summary As part of a perioperative blood management program, tranexamic acid can be used to help reduce blood loss and mitigate exposure to blood transfusion. PMID:25635366

    To explore what it means for parents to participate in their children's paediatric perioperative care. Allowing parents to participate in paediatric perioperative care can make a major difference for children in terms of their well-being, a decreased need for painkillers, fewer sleeping disorders and a more positive experience for both parties. The nurse anaesthetist should have a holistic view and develop a shared vision for the child, the parents and for themselves to perform successful paediatric perioperative care. Descriptive qualitative study. The study was conducted in 2014. Data were collected in 20 narrative interviews with 15 mothers and five fathers who had experience of participating in their child's paediatric perioperative day surgery. The analysis was carried out with qualitative content analysis to describe the variations, differences and similarities in the experiences. The analysis revealed a main category that describes that parental participation in the context of paediatric perioperative care in day surgery meant 'having strength to participate despite an increased vulnerability'. Three generic categories with additional subcategories explained what was essential for the parents to be able to preserve this strength and participate in their child's care despite their increased vulnerability. The generic categories were named, 'gaining information about what will happen', 'being seen as a resource' and 'gaining access to the environment'. Efforts should be made to improve parents' roles and opportunities to participate in paediatric perioperative care. Nurse anaesthetists have a crucial role in enabling parents' participation and need knowledge to develop strategies and nursing interventions that meet parents' needs. © 2017 John Wiley & Sons Ltd.

    Evidence suggests that perioperative allogeneic blood transfusion increases the risk of infectious complications after major surgery and of cancer recurrence after curative operation. This has been attributed to immunosuppression. Several authors have suggested that filtered whole blood and/or red...... cell concentrate, or leucocyte- and buffy coat-reduced red cells in artificial medium or their own plasma, may reduce postoperative immunosuppression. It was also anticipated that the use of autologous blood might minimize the risk of perioperative transfusion, but studies have unexpectedly shown...... similar postoperative infectious complications and cancer recurrence and/or survival rates in patients receiving autologous blood donated before operation and those receiving allogeneic blood. Future studies should identify common risk factors associated with blood storage....

    In past decades, Duchenne muscular dystrophy patients have been living longer and as the disease advances, patients experience multisystemic deterioration. Older patients often require gastrostomy tube placement for nutritional support. For optimizing the perioperative care, a practice of multidisciplinary team can better anticipate, prevent, and manage possible complications and reduce the overall perioperative morbidity and mortality. The aim of this study was to review our experience with perioperative care of adolescent and young adults with Duchenne muscular dystrophy undergoing gastrostomy by various surgical approaches in order to identify challenges and improve future perioperative care coordination to reduce morbidity. We retrospectively examined cases of gastrostomy tube placement in patients of ages 15 years and older between 2005 and 2016. We reviewed preoperative evaluation, anesthetic and surgical management, and postoperative complications. Twelve patients were identified; 1 had open gastrostomy, 3 laparoscopic gastrostomies, 5 percutaneous endoscopic guided, and 3 radiologically inserted gastrostomy tubes. All patients had preoperative cardiac evaluation with 6 patients demonstrating cardiomyopathy. Nine patients had preoperative pulmonary consultations and the pulmonary function tests reported forced vital capacity of ≤36% of predicted. Eight patients were noninvasive positive pressure ventilation dependent. General anesthesia with tracheal intubation was administered in 8 patients, and intravenous sedation in 4 patients; 1 received sedation supplemented with regional anesthesia and 3 received deep sedation. One patient had a difficult intubation that resulted in trauma and prolonged tracheal intubation. Three patients developed postoperative respiratory complications. Two patients' procedures were postponed due to inadequate preoperative evaluation and 1 because of disagreement between anesthesia and procedural services as to the optimal

    The surgery unit is a particularly labor-intensive environment in the hospital. Studies reflect the correlation of labor risk factors for musculoskeletal injuries among nurses but few have investigated the relationship to perioperative nurses. The purpose of this study is the identification and definition of ergonomic risk factors in the operating room and their connection with musculoskeletal disorders in perioperative nurses in regional hospitals in Greece. Forty four Greek perioperative nurses working in regional hospitals in southern Peloponnese participated. Anonymous self-administered questionnaire was used to collect the data, which consisted of three parts (investigating musculoskeletal symptoms, description of work, psychometric evaluation). The analysis was done with the statistical program SPSS.19. Symptoms of musculoskeletal problems emerged. Specifically, 54.4% in the lumbar, 47.7% in the neck, 45.5% in the shoulder, followed by smaller percentages of the hip, knee, elbow and ankle. 6.8% of participants indicated no musculoskeletal symptoms in the last year while 74.9% of those who had symptoms presented them in two or more areas. Activities rated as a major problem among others were the manual handling, tools with weight and vibration etc. 100% of respondents agreed that the work in the surgery unit is demanding and has anxiety. The lack of support from the government (81.8%), combined with the low perioperative nurses (6.8%) having the opportunity to participate in administrative decisions concerning them were related to problems in the organization and management of work. Apart from engineers target factors, a main aim should be the organization of work within the framework of a national policy based on European directives on the protection and promotion of the health and safety of workers.

    To summarize the surgical technique and perioperative management of laparoscopic sleeve gastrectomy (LSG). A total of 57 morbid obesity patients undergoing LSG surgery from May 2010 to December 2012 were enrolled in the study, whose clinical data in perioperative period were analyzed retrospectively. These patients had more than 1 year of follow-up. All the patients received preoperative preparation and postoperative management, and postoperative excess weight loss(EWL%) and improvement of preoperative complications was evaluated. All the cases completed the operation under laparoscopy, except 1 case because of the abdominal extensive adhesion. The average operation time was(102.0±15.2) min and the mean intraoperative blood loss (132.3±45.6) ml. Of 2 postoperative hemorrhage patients, 1 case received conservative treatment, and another one underwent laparoscopic exploration. The EWL% at 3 months, 6 months and 1 year after procedure was (54.9±13.8)%, (79.0±23.6)% and (106.9±25.1)% respectively. The preoperative complications were improved in some degree. There were no operative death, and anastomotic leak, anastomotic stenosis, or surgical site infection occurred. LSG is a safe and effective surgical technique, whose safety and efficacy may be increased by improving the perioperative management.

    Cardiovascular complications are important causes of morbidity and mortality in patients undergoing elective non-cardiac surgery, with adverse cardiac outcomes estimated to occur in approximately 4% of all patients. Anti-platelet therapy withdrawal may precede up to 10% of acute cardiovascular syndromes, with withdrawal in the peri-operative setting incompletely appraised. The aims of our study were to determine the proportion of patients undergoing elective non-cardiac surgery currently prescribed anti-platelet therapy, and identify current practice in peri-operative management. In addition, the relationship between management of anti-platelet therapy and peri-operative cardiac risk was assessed. We evaluated consecutive patients attending elective non-cardiac surgery at a major tertiary referral centre. Clinical and biochemical data were collected and analysed on patients currently prescribed anti-platelet therapy. Peri-operative management of anti-platelet therapy was compared with estimated peri-operative cardiac risk. Included were 2950 consecutive patients, with 516 (17%) prescribed anti-platelet therapy, primarily for ischaemic heart disease. Two hundred and eighty nine (56%) patients had all anti-platelet therapy ceased in the peri-operative period, including 49% of patients with ischaemic heart disease and 46% of patients with previous coronary stenting. Peri-operative cardiac risk score did not influence anti-platelet therapy management. Approximately 17% of patients undergoing elective non-cardiac surgery are prescribed anti-platelet therapy, the predominant indication being for ischaemic heart disease. Almost half of all patients with previous coronary stenting had no anti-platelet therapy during the peri-operative period. The decision to cease anti-platelet therapy, which occurred commonly, did not appear to be guided by peri-operative cardiac risk stratification. Copyright © 2012 Elsevier Ireland Ltd.

    The perioperative environment generates large amounts of waste, which negatively affects local and global ecosystems. To manage this waste health care facility leaders must focus on identifying correctable issues, work with relevant stakeholders to promote solutions, and adopt systematic procedural changes. Nurses and managers can moderate negative environmental effects by promoting reduction, recycling, and reuse of materials in the perioperative setting.

    A perioperative handoff protocol provides a standardized delivery of communication during a handoff that occurs from the operating room to the postanestheisa care unit or ICU. The protocol's success is dependent, in part, on its continued proper use over time. A novel process audit was developed to help ensure that a perioperative handoff protocol is used accurately and appropriately over time. The Audit Observation Form is used for the Audit Phase of the process audit, while the Audit Averages Form is used for the Data Analysis Phase. Employing minimal resources and using quantitative methods, the process audit provides the necessary means to evaluate the proper execution of any perioperative handoff protocol.

    2018-03-01

    Full Text Available Enoxaparin is a widely used low-molecular-weight heparin for perioperative thromboembolic prophylaxis. Enoxaparin-induced skin necrosis in the setting of arthroplasty has been rarely reported in the literature with varying outcomes and management decisions. Our patient developed skin necrosis at his injection site and thrombocytopenia 10 days following left total knee arthroplasty surgery and after receiving subcutaneous Lovenox injections postoperatively. The patient was started on an alternative anticoagulation based on a high suspicion for heparin-induced thrombocytopenia and the wound was monitored without surgical debridement. Our case highlights the key clinical management decisions when facing this potentially life-threatening adverse reaction. Keywords: Lovenox, Enoxaparin, Skin necrosis, Adverse reaction, Arthroplasty

    The present paper focuses on the process of understanding the patient in the context of perioperative caring and reports a story narrated by a perioperative nurse as well as her emerging understanding of the patient prior to surgery at an operating department. This qualitative case study had a dual purpose; firstly, to describe how the perioperative nurse's understanding of the patient emerged and, secondly, to establish how the researcher interpreted the situation. As a perioperative nurse and researcher, the author is both the narrator and interpreter. To date we have rarely discussed the fact that, in a perioperative context, the patient might feel ashamed of his/her body, even before arriving at the operating department. This new understanding emerged from the hermeneutical dialogue in the present study. © 2013 Wiley Publishing Asia Pty Ltd.

    This study was carried out to improve patient safety in the operating theatre by the introduction of perioperative briefing and debriefing, which focused on an optimal collaboration between surgical team members. A prospective intervention study with one pretest and two post-test measurements: 1 month before and 4 months and 2.5 years after the implementation of perioperative briefing and debriefing, respectively. Operating theatres of a tertiary care hospital with 875 beds in the Netherlands. All members of five surgical teams participated in the perioperative briefing and debriefing. The implementation of perioperative briefing and debriefing from July 2012 to January 2014. The primary outcome was changes in the team climate, measured by the Team Climate Inventory. Secondary outcomes were the experiences of surgical teams with perioperative briefing and debriefing, measured with a structured questionnaire, and the duration of the briefings, measured by an independent observer. Two and a half years after the introduction of perioperative briefing and debriefing, the team climate increased statistically significant (p≤0.05). Members of the five surgical teams strongly agreed with the positive influence of perioperative briefing and debriefing on clear agreements and reminding one another of the agreements of the day. They perceived a higher efficiency of the surgical programme with more operations starting on time and less unexpectedly long operation time. The perioperative briefing took less than 4 min to conduct. Perioperative briefing and debriefing improved the team climate of surgical teams and the efficiency of their work within the operating theatre with acceptable duration per briefing. Surgical teams with alternating team compositions have the most benefit of briefing and debriefing. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  8. Radiation impairs perineural invasion by modulating the nerve microenvironment.

    Directory of Open Access Journals (Sweden)

    Richard L Bakst

    Full Text Available Perineural invasion (PNI by cancer cells is an ominous clinical event that is associated with increased local recurrence and poor prognosis. Although radiation therapy (RT may be delivered along the course of an invaded nerve, the mechanisms through which radiation may potentially control PNI remain undefined.An in vitro co-culture system of dorsal root ganglia (DRG and pancreatic cancer cells was used as a model of PNI. An in vivo murine sciatic nerve model was used to study how RT to nerve or cancer affects nerve invasion by cancer.Cancer cell invasion of the DRG was partially dependent on DRG secretion of glial-derived neurotrophic factor (GDNF. A single 4 Gy dose of radiation to the DRG alone, cultured with non-radiated cancer cells, significantly inhibited PNI and was associated with decreased GDNF secretion but intact DRG viability. Radiation of cancer cells alone, co-cultured with non-radiated nerves, inhibited PNI through predominantly compromised cancer cell viability. In a murine model of PNI, a single 8 Gy dose of radiation to the sciatic nerve prior to implantation of non-radiated cancer cells resulted in decreased GDNF expression, decreased PNI by imaging and histology, and preservation of sciatic nerve motor function.Radiation may impair PNI through not only direct effects on cancer cell viability, but also an independent interruption of paracrine mechanisms underlying PNI. RT modulation of the nerve microenvironment may decrease PNI, and hold significant therapeutic implications for RT dosing and field design for patients with cancers exhibiting PNI.

    To assess the role of a Toyota production system (TPS) quality improvement (QI) intervention on appropriateness of perioperative antibiotic therapy and in length of hospital stay (LOS) among surgical patients. Pre-post quasi-experimental study using local and national retrospective cohorts. We used TPS methods to implement a multifaceted intervention to reduce nosocomial methicillin-resistant Staphylococcus aureus infections on a Veterans Affairs surgical unit, which led to a QI intervention targeting appropriate perioperative antibiotic prophylaxis. Appropriate perioperative antibiotic therapy was defined as selection of the recommended antibiotic agents for a duration not exceeding 24 hours from the time of the operation. The local computerized medical record system was used to identify patients undergoing the 25 most common surgical procedures and to examine changes in appropriate antibiotic therapy and LOS over time. Overall, 2550 surgical admissions were identified from the local computerized medical records. The proportion of surgical admissions receiving appropriate perioperative antibiotics was significantly higher (P <.01) in 2004 after initiation of the TPS intervention (44.0%) compared with the previous 4 years (range, 23.4%-29.8%) primarily because of improvements in compliance with antibiotic therapy duration rather than appropriate antibiotic selection. There was no statistically significant decrease in LOS over time. The use of TPS methods resulted in a QI intervention that was associated with an increase in appropriate perioperative antibiotic therapy among surgical patients, without affecting LOS.

  10. The role of perioperative warming in surgery: a systematic review

    Full Text Available OBJECTIVE: The objective of this review was to systematically analyze the trials on the effectiveness of perioperative warming in surgical patients. METHODS: A systematic review of the literature was undertaken. Clinical trials on perioperative warming were selected according to specific criteria and analyzed to generate summative data expressed as standardized mean difference (SMD. RESULTS: Twenty-five studies encompassing 3,599 patients in various surgical disciplines were retrieved from the electronic databases. Nineteen randomized trials on 1785 patients qualified for this review. The no-warming group developed statistically significant hypothermia. In the fixed effect model, the warming group had significantly less pain and lower incidence of wound infection, compared with the no-warming group. In the random effect model, the warming group was also associated with lower risk of post-anesthetic shivering. Both in the random and the fixed effect models, the warming group was associated with significantly less blood loss. However, there was significant heterogeneity among the trials. CONCLUSION: Perioperative warming of surgical patients is effective in reducing postoperative wound pain, wound infection and shivering. Systemic warming of the surgical patient is also associated with less perioperative blood loss through preventing hypothermia-induced coagulopathy. Perioperative warming may be given routinely to all patients of various surgical disciplines in order to counteract the consequences of hypothermia.

    Nutrition status prior to surgery and nutrition rehabilitation after surgery can affect the morbidity and mortality of pediatric patients. A comprehensive approach to nutrition in pediatric surgical patients is important and includes preoperative assessment, perioperative nutrition considerations, and postoperative recovery. A thorough nutrition assessment to identify patients who are at nutrition risk prior to surgery is important so that the nutrition status can be optimized prior to the procedure to minimize suboptimal outcomes. Preoperative malnutrition is associated with increased complications and mean hospital days following surgery. Enteral and parenteral nutrition can be used in cases where food intake is inadequate to maintain and possibly improve nutrition status, especially in the 7-10 days prior to surgery. In the perioperative period, fasting should be limited to restricting solid foods and non-human milk 6 hours prior to the procedure and allowing clear liquids until 2 hours prior to the procedure. Postoperatively, early feeding has been shown to resolve postoperative ileus earlier, decrease infection rates, promote wound healing, and reduce length of hospital stay. If nutrition cannot be provided orally, then nutrition through either enteral or parenteral means should be initiated within 24-48 hours of surgery. Practitioners should identify those patients who are at the highest nutrition risk for postsurgical complications and provide guidance for optimal nutrition during the perioperative and postoperative period. © 2015 American Society for Parenteral and Enteral Nutrition.

  14. Perioperative Management of Diabetes: A Review

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Diabetes increases the requirements of surgery as well as perioperative morbidity and mortality. Careful preoperative evaluation and treatment of cardiac and renal diseases, intensive intraoperative and postoperative management are essential to optimize the best outcome. Stress hyperglycemia in response to surgery, osmotic diuresis and hypoinsulinemia can lead to life threatening complications like ketoacidosis or hyperglycemic hyperosmolar syndrome. Wound healing is impaired by hyperglycemia and chance of postoperative wound infection is more in diabetics. Therefore aseptic precautions must be taken. Adequate insulin, glucose, fluid and electrolytes should be provided for good metabolic control. Though some current study reveals that oral hypoglycemic agents can be used for the effective management of perioperative diabetes; the adverse effects of newly introduced agents need more clinical observations. Subcutaneous administration of insulin as in Sliding Scale may be a less preferable method, because of unreliable absorption and unpredictable blood glucose. Intravenous administration of rapid onset soluble (short acting insulin as in Alberti (GIK regimen, is safe and effective method controlling perioperative hyperglycemia. Patient with type 1 diabetes needs frequent monitoring of glucose, electrolytes and acid-base balance as chance of high hyperglycemia and ketoacidosis is more. In case of emergency surgery assessment for diabetic ketoacidosis (DKA and meticulous management is essential. Postoperative pain and hyperglycemia should be treated carefully to avoid complications.

    To construct a reliable, accurate, and easy-to-use handheld computer database that facilitates the point-of-care acquisition of perioperative text and image data specific to rhinoplasty. A user-modified database (Pendragon Forms [v.3.2]; Pendragon Software Corporation, Libertyville, Ill) and graphic image program (Tealpaint [v.4.87]; Tealpaint Software, San Rafael, Calif) were used to capture text and image data, respectively, on a Palm OS (v.4.11) handheld operating with 8 megabytes of memory. The handheld and desktop databases were maintained secure using PDASecure (v.2.0) and GoldSecure (v.3.0) (Trust Digital LLC, Fairfax, Va). The handheld data were then uploaded to a desktop database of either FileMaker Pro 5.0 (v.1) (FileMaker Inc, Santa Clara, Calif) or Microsoft Access 2000 (Microsoft Corp, Redmond, Wash). Patient data were collected from 15 patients undergoing rhinoplasty in a private practice outpatient ambulatory setting. Data integrity was assessed after 6 months' disk and hard drive storage. The handheld database was able to facilitate data collection and accurately record, transfer, and reliably maintain perioperative rhinoplasty data. Query capability allowed rapid search using a multitude of keyword search terms specific to the operative maneuvers performed in rhinoplasty. Handheld computer technology provides a method of reliably recording and storing perioperative rhinoplasty information. The handheld computer facilitates the reliable and accurate storage and query of perioperative data, assisting the retrospective review of one's own results and enhancement of surgical skills.

    Complications after cardiac surgery are common and lead to substantial increases in morbidity and mortality. Meta-analyses of small randomized trials have suggested that perioperative statin therapy can prevent some of these complications. We randomly assigned 1922 patients in sinus rhythm who were scheduled for elective cardiac surgery to receive perioperative rosuvastatin (at a dose of 20 mg daily) or placebo. The primary outcomes were postoperative atrial fibrillation within 5 days after surgery, as assessed by Holter electrocardiographic monitoring, and myocardial injury within 120 hours after surgery, as assessed by serial measurements of the cardiac troponin I concentration. Secondary outcomes included major in-hospital adverse events, duration of stay in the hospital and intensive care unit, left ventricular and renal function, and blood biomarkers. The concentrations of low-density lipoprotein cholesterol and C-reactive protein after surgery were lower in patients assigned to rosuvastatin than in those assigned to placebo (PSTICS ClinicalTrials.gov number, NCT01573143.).

    Full Text Available Jorinde AW Polderman, Robert van Wilpe, Jan H Eshuis, Benedikt Preckel, Jeroen Hermanides Department of Anaesthesiology, Academic Medical Centre, University of Amsterdam, Amsterdam, the Netherlands Abstract: Given the growing number of patients with diabetes mellitus (DM and the growing number of surgical procedures performed in an ambulatory setting, DM is one of the most encountered comorbidities in patients undergoing ambulatory surgery. Perioperative management of ambulatory patients with DM requires a different approach than patients undergoing major surgery, as procedures are shorter and the stress response caused by surgery is minimal. However, DM is a risk factor for postoperative complications in ambulatory surgery, so should be managed carefully. Given the limited time ambulatory patients spend in the hospital, improvement in management has to be gained from the preanesthetic assessment. The purpose of this review is to summarize current literature regarding the anesthesiologic management of patients with DM in the ambulatory setting. We will discuss the risks of perioperative hyperglycemia together with the pre-, intra-, and postoperative considerations for these patients when encountered in an ambulatory setting. Furthermore, we provide recommendations for the optimal perioperative management of the diabetic patient undergoing ambulatory surgery.

    Sculco, Peter K; Pagnano, Mark W

    2015-04-01

    Rapid recovery after total joint arthroplasty requires patients to get ahead and stay ahead or the four impediments to early rehabilitation and discharge: volume depletion, blood loss, pain, and nausea. Adequate volume resuscitation starts before entering the operating room and focuses on intravenous fluids rather than red blood cell transfusion. Tranexamic acid limits blood loss and reduces the need for most other blood management systems. Rapid recovery pain management focuses on minimizing parenteral opioids. A short-acting spinal with a peri-articular local anesthetic injection is reliable, reproducible, and safe. Patients at risk for post-operative nausea are treated with anti-emetic medications and perioperative dexamethasone. These interventions reflect a transition from the sick-patient model to the well-patient model and make rapid recovery joint arthroplasty a reality in 2015. Copyright © 2015 Elsevier Inc.

    The aim of this study was to describe operating theatre nurses' (OTNs') perceptions of caring in perioperative practice. A qualitative descriptive design was performed. Data were collected with interviews were carried out with fifteen strategically selected operating theatre nurses from different operating theatres in the middle of Sweden. A phenomenographic analysis was used to analyse the interviews. The findings show that operating theatre nurses' perceptions of caring in perioperative practice can be summarised in one main category: To follow the patient all the way. Two descriptive categories emerged: To ensure continuity of patient care and keeping a watchful eye. The operating theatre nurses got to know the patient and as a result became responsible for the patient. They protected the patient's body and preserved patient dignity in perioperative practice. The findings show different aspects of caring in perioperative practice. OTNs wanted to be more involved in patient care and follow the patient throughout the perioperative nursing process. Although OTNs have the ambition to make the care in perioperative practice visible, there is today a medical technical approach which promotes OTNs continuing to offer care in secret. © 2014 Nordic College of Caring Science.

    Full Text Available Cold urticaria consists of an allergic immune response to cold temperatures with symptoms ranging from pruritic wheals to life-threatening angioedema, bronchospasm, or anaphylactic shock. Adequate planning to maintain normothermia perioperatively is vital due to impaired hypothalamic thermoregulation and overall depression of sympathetic outflow during deep sedation and general anesthesia. This case report describes the successful perioperative management of a 45-year-old female with a history of cold urticaria undergoing a laparoscopic Nissen fundoplication for refractory gastroesophageal reflux disease and discusses how to appropriately optimize the care of these patients.

    Objective To determine the relationship of perioperative hyperglycemia and insulin administration on outcomes in elective colon/rectal and bariatric operations. Background There is limited evidence to characterize the impact of perioperative hyperglycemia and insulin on adverse outcomes in patients, with and without diabetes, undergoing general surgical procedures. Methods The Surgical Care and Outcomes Assessment Program is a Washington State quality improvement benchmarking-based initiative. We evaluated the relationship of perioperative hyperglycemia (>180 mg/dL) and insulin administration on mortality, reoperative interventions, and infections for patients undergoing elective colorectal and bariatric surgery at 47 participating hospitals between fourth quarter of 2005 and fourth quarter of 2010. Results Of the 11,633 patients (55.4 ± 15.3 years; 65.7% women) with a serum glucose determination on the day of surgery, postoperative day 1, or postoperative day 2, 29.1% of patients were hyperglycemic. After controlling for clinical factors, those with hyperglycemia had a significantly increased risk of infection [odds ratio (OR) 2.0; 95% confidence interval (CI), 1.63–2.44], reoperative interventions (OR, 1.8; 95% CI, 1.41–2.3), and death (OR, 2.71; 95% CI, 1.72–4.28). Increased risk of poor outcomes was observed both for patients with and without diabetes. Those with hyperglycemia on the day of surgery who received insulin had no significant increase in infections (OR, 1.01; 95% CI, 0.72–1.42), reoperative interventions (OR, 1.29; 95% CI, 0.89–1.89), or deaths (OR, 1.21; 95% CI, 0.61–2.42). A dose-effect relationship was found between the effectiveness of insulin-related glucose control (worst 180–250 mg/dL, best adverse outcomes. Conclusions Perioperative hyperglycemia was associated with adverse outcomes in general surgery patients with and without diabetes. However, patients with hyperglycemia who received insulin were at no greater risk than

    'Standardised Endpoints for Perioperative Medicine' (StEP) is an international collaboration undertaking development of consensus-based consistent definitions for endpoints in perioperative clinical trials. Inconsistency in endpoint definitions can make interpretation of trial results more difficult, especially if conflicting evidence is present. Furthermore, this inconsistency impedes evidence synthesis and meta-analyses. The goals of StEP are to harmonise definitions for clinically meaningful endpoints and specify standards for endpoint reporting in clinical trials. To help inform this endeavour, we aim to conduct a scoping review to systematically characterise the definitions of clinically important endpoints in the existing published literature on perioperative blood loss and transfusion. The scoping review will be conducted using the widely adopted framework developed by Arksey and O'Malley, with modifications from Levac. We refined our methods with guidance from research librarians as well as researchers and clinicians with content expertise. The electronic literature search will involve several databases including Medline, PubMed-not-Medline and Embase. Our review has three objectives, namely to (1) identify definitions of significant blood loss and transfusion used in previously published large perioperative randomised trials; (2) identify previously developed consensus-based definitions for significant blood loss and transfusion in perioperative medicine and related fields; and (3) describe the association between different magnitudes of blood loss and transfusion with postoperative outcomes. The multistage review process for each question will involve two reviewers screening abstracts, reading full-text articles and performing data extraction. The abstracted data will be organised and subsequently analysed in an iterative process. This scoping review of the previously published literature does not require research ethics approval. The results will be used

    Background: Routine lumbar spine magnetic resonance imaging (MRI) may not show any evidence of the cause of sciatica in some cases. The relationship between nerve root compression detected on lumbar MRI and sciatica is also sometimes uncertain. Purpose: To ascertain whether axial (and, when necessary, sagittal and coronal) short-tau inversion recovery or fat-saturated T2-weighted MRI findings can be used to study the level of sciatica in patients with a non-yielding routine MRI examination. Material and Methods: A total of 215 patients with unilateral sciatica underwent MRI. All patients were asked to complete pain drawing forms describing their pain dermatomal distributions. Perineural edema/inflammation corresponding to the pain location indicated by the pain drawings was sought on short-tau inversion recovery or fat-saturated T2-weighted images. Results: Routine MRI findings revealed that 110 of the 215 patients had nerve root compromise related to the patients' symptoms. Routine MRI could not ascertain the cause of these symptoms in the remaining 105 patients. In 31 (29.5%) of these 105 patients, short-tau inversion recovery or fat-saturated T2-weighted magnetic resonance images revealed perineural edema/inflammation surrounding the nerve roots related to the pain locations indicated in the pain drawings. Conclusion: Axial (and, when required, sagittal and coronal) short-tau inversion recovery or fat-saturated T2-weighted magnetic resonance images may be helpful for revealing additional findings in cases of unexplained sciatica in standard magnetic resonance imaging. However, the value of this imaging may be not great enough to justify routine use of these additional sequences to study the level of sciatica

    Changes in surgical training have raised concerns about residents' operative exposure and preparedness for independent practice. One way of addressing this concern is by optimizing teaching and feedback in the operating room (OR). The objective of this study was to perform a systematic review on perioperative teaching and feedback. A systematic literature search identified articles from 1994 to 2014 that addressed teaching, feedback, guidance, or debriefing in the perioperative period. Data was extracted according to ENTREQ guidelines, and a qualitative analysis was performed. Thematic analysis of the 26 included studies identified four major topics. Observation of teaching behaviors in the OR described current teaching practices. Identification of effective teaching strategies analyzed teaching behaviors, differentiating positive and negative teaching strategies. Perceptions of teaching behaviors described resident and attending satisfaction with teaching in the OR. Finally models for delivering structured feedback cited examples of feedback strategies and measured their effectiveness. This study provides an overview of perioperative teaching and feedback for surgical trainees and identifies a need for improved quality and quantity of structured feedback.

    Pulmonary hypertensive crisis is an important cause of morbidity and mortality in patients with pulmonary arterial hypertension secondary to congenital heart disease (PAH-CHD) who require cardiac surgery. At present, prevention and management of perioperative pulmonary hypertensive crisis is aimed at optimizing cardiopulmonary interactions by targeting prostacyclin, endothelin, and nitric oxide signaling pathways within the pulmonary circulation with various pharmacological agents. This review is aimed at familiarizing the practitioner with the current pharmacological treatment for dealing with perioperative pulmonary hypertensive crisis in PAH-CHD patients. Given the life-threatening complications associated with pulmonary hypertensive crisis, proper perioperative planning can help anticipate cardiopulmonary complications and optimize surgical outcomes in this patient population.

    Post-surgical infections (PSIs) are a source of preventable perioperative morbidity. No guidelines exist for the use of perioperative antibiotics in pediatric urologic procedures. This study reports the rate of PSIs in non-endoscopic pediatric genitourinary procedures at our institution. Secondary aims evaluate the association of PSI with other perioperative variables, including wound class (WC) and perioperative antibiotic administration. Data from consecutive non-endoscopic pediatric urologic procedures performed between August 2011 and April 2014 were examined retrospectively. The primary outcome was the rate of PSIs. PSIs were classified as superficial skin (SS) and deep/organ site (D/OS) according to Centers for Disease Control and Prevention guidelines, and urinary tract infection (UTI). PSIs were further stratified by WC1 and WC2 and perioperative antibiotic usage. A relative risk and chi-square analysis compared PSI rates between WC1 and WC2 procedures. A total of 1185 unique patients with 1384 surgical sites were reviewed; 1192 surgical sites had follow-up for inclusion into the study. Ten total PSIs were identified, for an overall infection rate of 0.83%. Of these, six were SS, one was D/OS, and three were UTIs. The PSI rate for WC1 (885 sites) and WC2 (307 sites) procedures was 0.34% and 2.28%, respectively, p antibiotics (0.35% vs. 0.33%). All WC2 procedures received antibiotics. Post-surgical infections are associated with significant perioperative morbidity. In some studies, PSI can double hospital costs, and contribute to hospital length of stay, admission to intensive care units, and impact patient mortality. Our study demonstrates that the rate of PSI in WC1 operations is low, irrespective of whether the patient received perioperative antibiotics (0.35%) or no antibiotics (0.33%). WC2 operations were the larger source of morbidity with an infection rate of 2.28% and a 6.7 fold higher increase in relative risk. WC1 procedures have a rate of

    To discuss the perioperative treatment of chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma. Retrospective analysis of perioperative clinical data of 43 cases with CRSwNP and asthma. The admitted and under endoscopic surgery. Patients with preventing perioperative asthma attacks and corresponding standardized treatment were Observed. Thirty-five cases were stable during perioperative period and without asthma. Seven patients diagnosed as mild and moderate asthma attacks because of low pulse oximetry (SpO2 92%-95%) and scattered wheeze heard in the lungs. So these patients were sent to ICU for the treatment. They went back to ward after their conditions turned to stable and no asthma during perioperative. One patient diagnosed as severe asthma attack, because irritability and suffocation happened, SpO2 decreased from 99% to 84%-81%, diffuse wheeze could be heard in the whole lung . So we give him tracheal intubation and sent him to ICU for advanced treatment after breathing smooth. Five days later the patient retuned to the ward in stable condition and with no asthma attack again. Before operation the patients should be give some corresponding standardized comprehensive treatment according to the nasal symptoms and the degree of asthma attack, such as the application of topical steroid and antiallergic medicine. And some special treatment should be given to reduce airway hyperresponsiveness mucosa during anesthesia. These methods can reduce the risk of the asthma attacks and improve perioperative safety, prevent serious complications.

    Purpose: To identify the risk factors for perioperative morbidity in patients undergoing resection of primary rectal cancer, with a specific focus on the effect of neoadjuvant therapy. Methods and Materials: This exploratory analysis of prospectively collected data included all patients who underwent anterior resection/low anterior resection or abdominoperineal resection for primary rectal cancer between October 2001 and October 2006. The study endpoints were perioperative surgical and medical morbidity. Univariate and multivariate analyses of potential risk factors were performed. Results: A total of 485 patients were included in this study; 425 patients (88%) underwent a sphincter-saving anterior resection/low anterior resection, 47 (10%) abdominoperineal resection, and 13 (2%) multivisceral resection. Neoadjuvant chemoradiotherapy was performed in 100 patients (21%), and 168 (35%) underwent neoadjuvant short-term radiotherapy (5 x 5 Gy). Patient age and operative time were independently associated with perioperative morbidity, and operative time, body mass index >27 kg/m 2 (overweight), and resection type were associated with surgical morbidity. Age and a history of smoking were confirmed as independent prognostic risk factors for medical complications. Neoadjuvant therapy was not associated with a worse outcome. Conclusion: The results of this prospective study have identified several risk factors associated with an adverse perioperative outcome after rectal cancer surgery. In addition, neoadjuvant therapy was not associated with increased perioperative complications.

  11. Intravenous sub-anesthetic ketamine for perioperative analgesia

    Directory of Open Access Journals (Sweden)

    Andrew W Gorlin

    2016-01-01

    Full Text Available Ketamine, an N-methyl-d-aspartate antagonist, blunts central pain sensitization at sub-anesthetic doses (0.3 mg/kg or less and has been studied extensively as an adjunct for perioperative analgesia. At sub-anesthetic doses, ketamine has a minimal physiologic impact though it is associated with a low incidence of mild psychomimetic symptoms as well as nystagmus and double vision. Contraindications to its use do exist and due to ketamine′s metabolism, caution should be exercised in patients with renal or hepatic dysfunction. Sub-anesthetic ketamine improves pain scores and reduces perioperative opioid consumption in a broad range of surgical procedures. In addition, there is evidence that ketamine may be useful in patients with opioid tolerance and for preventing chronic postsurgical pain.

    Full Text Available Abstract Background Surgery is often advocated in patients with resectable pulmonary metastases from colorectal cancer (CRC. Our study aims to evaluate peri-operative chemotherapy in patients with metastastic CRC undergoing pulmonary metastasectomy. Methods Patients treated for CRC who underwent pulmonary metastasectomy by a single surgeon were identified. Outcome measures included survival, peri-operative complications, radiological and histological evidence of chemotherapy-induced lung toxicities. Results Between 1997 and 2009, 51 eligible patients were identified undergoing a total of 72 pulmonary resections. Thirty-eight patients received peri-operative chemotherapy, of whom 9 received an additional biological agent. Five-year overall survival rate was 72% in the whole cohort - 74% and 68% in those who received peri-operative chemotherapy (CS and those who underwent surgery alone (S respectively. Five-year relapse free survival rate was 31% in the whole cohort - 38% and ≤18% in CS and S groups respectively. Only 8% had disease progression during neoadjuvant chemotherapy. There were no post-operative deaths. Surgical complications occurred in only 4% of patients who received pre-operative chemotherapy. There was neither radiological nor histological evidence of lung toxicity in resected surgical specimens. Conclusions Peri-operative chemotherapy can be safely delivered to CRC patients undergoing pulmonary metastasectomy. Survival in this selected group of patients was favourable.

    Methadone is frequently administered to adults experiencing anesthesia and receiving pain treatment. Methadone pharmacokinetics in adults are well characterized, including the perioperative period. Methadone is also used in children. There is, however, no information on methadone pharmacokinetics in children of any age. The purpose of this investigation was to determine the pharmacokinetics of intravenous methadone in children undergoing surgery. Perioperative opioid-sparing effects were also assessed. Eligible subjects were children 5-18 yr undergoing general anesthesia and surgery, with an anticipated postoperative inpatient stay exceeding 3 days. Three groups of 10 to 11 patients each received intravenous methadone hydrochloride after anesthetic induction in ascending dose groups of 0.1, 0.2, and 0.3 mg/kg (up to 20 mg). Anesthetic care was not otherwise changed. Venous blood was obtained for 4 days, for stereoselective determination of methadone and metabolites. Pain assessments were made each morning. Daily and total opioid consumption was determined. Perioperative opioid consumption and pain was determined in a second cohort, which was matched to age, sex, race, ethnicity, surgical procedure, and length of stay, but not receiving methadone. The final methadone study cohort was 31 adolescents (14 ± 2 yr, range 10-18) undergoing major spine surgery for a diagnosis of scoliosis. Methadone pharmacokinetics were linear over the dose range 0.1-0.3 mg/kg. Disposition was stereoselective. Methadone administration did not dose-dependently affect postoperative pain scores, and did not dose-dependently decrease daily or total postoperative opioid consumption in spinal fusion patients. Methadone enantiomer disposition in adolescents undergoing surgery was similar to that in healthy adults.

    A diagnosis of perineural invasion (PNI), defined as cancer within or surrounding at least 33% of the nerve, leads to selection of aggressive treatment in squamous cell carcinoma (SCC). Recent mechanistic studies show that cancer and nerves interact prior to physical contact. The purpose of this study was to explore cancer-nerve interactions relative to clinical outcome. Biopsy specimens from 71 patients with oral cavity SCC were stained with hematoxylin and eosin and immunohistochemical (IHC; cytokeratin, S100, GAP43, Tuj1) stains. Using current criteria, PNI detection was increased with IHC. Overall survival (OS) tended to be poor for patients with PNI (P = .098). OS was significantly lower for patients with minimum tumor-nerve distance smaller than 5 μm (P = .011). The estimated relative death rate decreased as the nerve-tumor distance increased; there was a gradual drop off in death rate from distance equal to zero that stabilized around 500 μm. In PNI-negative patients, nerve diameter was significantly related to OS (HR 2.88, 95%CI[1.11,7.49]). Among PNI-negative nerves, larger nerve-tumor distance and smaller nerve diameter were significantly related to better OS, even when adjusting for T-stage and age (HR 0.82, 95% CI[0.72,0.92]; HR 1.27, 95% CI[1.00,1.62], respectively). GAP43, a marker for neuronal outgrowth, stained less than Tuj1 in nerves at greater distances from tumor (OR 0.76, 95% CI[0.73,0.79]); more GAP43 staining was associated with PNI. Findings from a small group of patients suggest that nerve parameters other than presence of PNI can influence outcome and that current criteria of PNI need to be re-evaluated to integrate recent biological discoveries.

    To describe the experiences of participation in perioperative care of 8- to 11-year-old children. All children have the right to participate in decisions that affect them and have the right to express their views in all matters that concern them. Allowing children to be involved in their perioperative care can make a major difference in terms of their well-being by decreasing fear and anxiety and having more positive experiences. Taking the views of children into account and facilitating their participation could thus increase the quality of care. Descriptive qualitative design. The study was conducted in 2013 and data were collected by narrative interviews with 10 children with experience from perioperative care in Sweden. Qualitative content analysis was chosen to describe the variations, differences and similarities in children's experiences of participation in perioperative care. The result showed that receiving preparatory information, lack of information regarding postoperative care and wanting to have detailed information are important factors for influencing children's participation. Interaction with healthcare professionals, in terms of being listened to, being a part of the decision-making and feeling trust, is important for children's participation in the decision-making process. Poor adaptation of the care environment to the children's needs, feeling uncomfortable while waiting and needs for distraction are examples of how the environment and the care in the operating theatre influence the children's experiences of participation. Efforts should be made to improve children's opportunities for participation in the context of perioperative care and further research is needed to establish international standards for information strategies and care environment that promotes children's participation in perioperative care. Nurse anaesthetists need to acquire knowledge and develop strategies for providing preparatory visits and information to children prior to

    Educators today need innovative teaching strategies to meet the learning needs of the multigenerational population of perioperative nurses. Emerging technologies, such as YouTube, the world's largest video-sharing web site, can be used as a component of an active learning strategy that can appeal to a broad group of nurses along the novice-to-expert proficiency continuum. Using video clips can be a useful method to engage learners and promote critical thinking, decision making, and creativity. YouTube videos can be used to teach skills or as a platform for discussion. Learners also can create and upload their own videos to educate others. Increased engagement and active learning can lead the perioperative nurse to a deeper understanding of the educational material. Copyright © 2012 AORN, Inc. Published by Elsevier Inc.

    To evaluate the impact of fellows' involvement on the peri-operative outcomes of robot-assisted partial nephrectomy (RAPN). We analysed 216 patients who underwent RAPN for a small renal tumour. We stratified our cohort into two groups according to the involvement of a fellow surgeon during the procedure: expert surgeon operating alone (expert group) and fellow operating under the supervision of the expert surgeon (fellow group). Peri-operative data were compared between the two groups. Linear and logistic regression analyses were performed to assess the impact of fellows' involvement on peri-operative and postoperative outcomes. Trifecta and margins ischaemia complications (MIC) score achievement rates were used to assess the quality of surgery in both the expert and fellow groups. Trifecta was defined as a combination of warm ischaemia time negative surgical margins and no peri-operative complications. MIC score was defined as negative surgical margins, ischaemia time Training fellows to perform RAPN is associated with longer operating time and WIT but does not appear to compromise other peri-operative outcomes. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

    2012-09-01

    Full Text Available Abstract Background Perioperative pain management has recently been revolutionized with the recognition of novel mechanisms and introduction of newer drugs. Many randomized trials have studied the use of the gabapentinoid anti-epileptic, pregabalin, in acute pain. Published systematic reviews suggest that using pregabalin for perioperative pain management may decrease analgesic requirements and pain scores, at the expense of troublesome side effects. A major limitation of the extant reviews is the lack of rigorous investigation of clinical characteristics that would maximize the benefit harms ratio in favor of surgical patients. We posit that effects of pregabalin for perioperative pain management vary by the type of surgical pain model and propose this systematic review protocol to update previous systematic reviews and investigate the heterogeneity in findings across subgroups of surgical pain models. Methods/Design Using a peer-reviewed search strategy, we will search key databases for clinical trials on perioperative pregabalin use in adults. The electronic searches will be supplemented by scanning the reference lists of included studies. No limits of language, country or year will be imposed. Outcomes will include pain; use of co-analgesia, particularly opioids; enhanced recovery; and drug-related harms. We will focus on the identification of surgical models and patient characteristics that have shown benefit and adverse effects from pregabalin. Two clinical experts will independently screen the studies for inclusion using eligibility criteria established a priori. Data extracted by the reviewers will then be verified. Publication bias will be assessed, as will risk of bias using the Cochrane Risk of Bias tool. Meta-analysis and meta-regression are planned if the studies are deemed statistically, methodologically and clinically homogenous. Evidence will be graded for its strength for a select number of outcomes. Discussion We will explore

    Ready access to equipment or product information is essential for the safe operation of the many items that a perioperative nurse is asked to use, troubleshoot, or maintain. One institution's solution for making manufacturer information available in the practice setting was to create a facility intranet site dedicated to OR equipment manuals. This site provides information access to perioperative nurses and support staff members and, ultimately, helps improve patient care. Published by Elsevier Inc. All rights reserved.

    Perioperative care is complex and involves multiple interconnected subsystems. Delayed starts, prolonged cases and overtime are common. Surgical procedures account for 40-70% of hospital revenues and 30-40% of total costs. Most planning and scheduling in healthcare is done without modern planning tools, which have potential for improving access by assisting in operations planning support. We identified key planning scenarios of interest to perioperative leaders, in order to examine the feasibility of applying combinatorial optimization software solving some of those planning issues in the operative setting. Perioperative leaders desire a broad range of tools for planning and assessing alternate solutions. Our modeled solutions generated feasible solutions that varied as expected, based on resource and policy assumptions and found better utilization of scarce resources. Combinatorial optimization modeling can effectively evaluate alternatives to support key decisions for planning clinical workflow and improving care efficiency and satisfaction.

    Haloperidol may prolong ECG QTc-duration but is often prescribed perioperatively to hip-fracture patients. We aimed to determine (1) how QTc-duration changes perioperatively, (2) whether low-dose haloperidol-use influences these changes, and (3) which clinical variables are associated with potentially dangerous perioperative QTc-prolongation (PD-QTc; increase >50 ms or to >500 ms). Prospective cohort study. Tertiary university teaching-hospital. Patients enrolled in a randomized controlled clinical trial of melatonin versus placebo on occurrence of delirium in hip-fracture patients. Data from ECGs made before and after hip surgery (1-3 days and/or 4-6 days post-surgery) were analyzed. QTc-duration was measured by hand, blinded for haloperidol and pre/post-surgery status. Clinical variables were measured at baseline. Mixed model analysis was used to estimate changes in QTc-duration. Risk-factors for PD-QTc were estimated by logistic regression analysis. We included 89 patients (mean age 84 years, 24% male); 39 were treated with haloperidol. Patients with normal pre-surgery QTc-duration (male ≤430 ms, female ≤450 ms) had a significant increase (mean 12 ms, SD 28) in QTc-duration. A significant decrease (mean 19 ms, SD 34) occurred in patients with prolonged pre-surgery QTc-duration (male >450ms, female >470 ms). Haloperidol-use did not influence the perioperative course of the QTc-interval (p=0.351). PD-QTc (n=8) was not associated with any of the measured risk-factors. QTc-duration changed differentially, increasing in patients with normal, but decreasing in patients with abnormal baseline QTc-duration. PD-QTc was not associated with haloperidol-use or other risk-factors. Low-dose oral haloperidol did not affect perioperative QTc-interval.

    Perioperative nurses must use critical thinking and sound clinical judgment to meet their patients' needs safely and effectively. This requires the integration and continual updating of large amounts of detailed clinical information. Innovative education strategies are designed to make teaching and learning more interesting and interactive, especially for the presentation of complex subject material. One interactive educational strategy is the use of games. Educational games can foster collaboration and critical thinking among peers and associates. An example of this was the Perioperative QuizBowl: Evidence-Based Practice presented at the annual AORN Congress from 2003 to 2010, which was used to teach and reinforce evidence-based practice in a fun, competitive way. Although AORN no longer presents this offering, the QuizBowl format demonstrates how educational games can support clinical practice. Copyright © 2011 AORN, Inc. Published by Elsevier Inc.

    The increasing number of opioid users among chronic pain patients, and opioid abusers among the general population, makes perioperative pain management challenging for health care professionals. Anesthesiologists, surgeons, and nurses should be familiar with some pharmacological phenomena which are typical of opioid users and abusers, such as tolerance, physical dependence, hyperalgesia, and addiction. Inadequate pain management is very common in these patients, due to common prejudices and fears. The target of preoperative evaluation is to identify comorbidities and risk factors and recognize signs and symptoms of opioid abuse and opioid withdrawal. Clinicians are encouraged to plan perioperative pain medications and to refer these patients to psychiatrists and addiction specialists for their evaluation. The aim of this review was to give practical suggestions for perioperative management of surgical opioid-tolerant patients, together with schemes of opioid conversion for chronic pain patients assuming oral or transdermal opioids, and patients under maintenance programs with methadone, buprenorphine, or naltrexone.

    The prevention of inadvertent perioperative hypothermia (IPH) remains an important issue in perioperative healthcare. The aims of this project were to: (i) assess current clinical practice in the management of IPH and (ii) promote best practice in the management of IPH in adult operating theatres. This project from August 2010 to March 2012 utilised a system of audit and feedback to implement best practice recommendations. Data were collected via chart audits against criteria developed from best practice recommendations for managing IPH. Evidence-based best practices, such as consistent temperature monitoring and patient warming, were implemented using multifaceted interventions. Perioperative records for 73 patients (baseline) and 72 patients (post-implementation) were audited. Post-implementation audit showed an increase in patients with temperatures >36°C admitted to the post-anaesthetic care unit (PACU) (8%) and discharged from PACU (28%). The percentage of patients receiving preoperative temperature monitoring increased (38%); however, low levels of intraoperative monitoring remained (31% of patients with surgery of 30 min or longer duration). Small increases were found in patient warming of 5% intraoperatively and 8% postoperatively. Preoperative warming was not successfully implemented during this phase of the project. Temperature monitoring, warming and rates of normothermia improved; however, barriers to best practice of IPH management were experienced, which negatively impacted on the project. Further stages of implementation and audit were added to further address IPH management in this department. © 2013 The Authors.

    Full Text Available Abstract Background Image guided spinal injections are successfully used in the management of low back pain and sciatica. The main benefit of CT-guided injections is the safe, fast and precise needle placement, but the radiation exposure remains a serious concern. The purpose of the study was to test a new institutional low-dose protocol for CT-guided periradicular injections in lumbar spine to reduce radiation exposure while increasing accuracy and safety for the patients. Methods We performed a retrospective analysis of a prospective database during a 4-month period (Oct-Dec 2011 at a German University hospital using a newly established low-dose-CT-protocol for periradicular injections in patients suffering from lumbar disc herniation and nerve root entrapment. Inclusion criteria were acute or chronic nerve root irritation due to lumbar disc hernia, age over 18, compliance and informed consent. Excluded were patients suffering from severe obesity (BMI > 30, coagulopathy, allergy to injected substances, infection and non-compliant patients. Outcome parameters consisted of the measured dose length product (mGycm2, the amount of scans, age, gender, BMI and the peri-interventional complications. The results were compared to 50 patients, treated in the standard-interventional CT-protocol for spinal injections, performed in June-Oct 2011, who met the above mentioned inclusion criteria. Results A total amount of 100 patients were enrolled in the study. A significant radiation dose reduction (average 85.31% was achieved using the institutional low-dose protocol compared to standard intervention mode in CT-guided periradicular injections in lumbar spine. Using the low-dose protocol did not increase the complications rate in the analyzed cohort. Conclusions Low-dose-CT-protocols for lumbar perineural injections significantly reduce the exposure to radiation of non-obese patients without an increase of complications. This increases long-time patient

    2016-03-01

    Thanks to the progress of surgical theory and skills, as well as the application of modern medical devices in general surgery, both the occurrence of perioperative complications and mortality of gastrointestinal surgery have significantly reduced recently. However, it is still far from optimal in terms of the perioperative venous thromboembolism (VTE) management in gastrointestinal cancer, and what is responsible for that? This paper aims at finding out the reasons contributing to the current status, giving suggestions for how to make improvement at both disease level and hospital management level. At the same time, while paying attention for the prophylaxis of VTE, there have been more and more patients receiving antithrombotic treatment require elective or emergent surgery in clinical practice, due to aging and increased incidence of cardiovascular disease year by year. How to balance the bleeding and thrombosis risk for these patients during perioperative periods is also a question we are going to discuss. In conclusion, as to the issue of the management of perioperative thrombosis, there will be a long way for Chinese doctors to go. Our peers should pay more attention to this problem and take more efforts, so that the thrombotic complications in surgical patients can be reduced.

    2017-11-01

    Early surgical education is required for neurosurgical residents to learn many surgical procedures. However, the participation of less experienced residents may increase perioperative complication rates. Perioperative complication studies in the field of neurosurgery are being increasingly published; however, studies have not yet focused on cervical laminoplasty. The study population included 193 consecutive patients who underwent cervical laminoplasty in Tokyo Metropolitan Neurological Hospital between 2008 and 2014. Patient and surgeon background factors, as well as perioperative complication rates were retrospectively compared between resident and board-certified spine neurosurgeon groups. Deteriorated or newly developed neurological deficits and surgical site complications within 30days of cervical laminoplasty were defined as perioperative complications. Out of 193 patients, 123 (64%) were operated on by residents as the first operator and 70 (36%) by board-certified spine neurosurgeons. No significant differences were observed in patient and surgeon factors between the two groups, except for hyperlipidemia (13 vs 17, p=0.02). Furthermore, no significant differences were noted in perioperative complication rates between the two groups (7 [5.7%] vs 4 [5.7%], p=1). Cervical laminoplasty performed in a standardized manner by residents who received their surgical training in our hospital did not increase perioperative complication rates, and ensured the safety of patients.

    Medical personnel in hospitals often works under great physical and mental strain. In medical decision-making, errors can never be completely ruled out. Several studies have shown that between 50 and 60% of adverse events could have been avoided through better organization, more attention or more effective security procedures. Critical situations especially arise during interdisciplinary collaboration and the use of complex medical technology, for example during surgical interventions and in perioperative settings (the period of time before, during and after surgical intervention). In this paper, we present an ontology and an ontology-based software system, which can identify risks across medical processes and supports the avoidance of errors in particular in the perioperative setting. We developed a practicable definition of the risk notion, which is easily understandable by the medical staff and is usable for the software tools. Based on this definition, we developed a Risk Identification Ontology (RIO) and used it for the specification and the identification of perioperative risks. An agent system was developed, which gathers risk-relevant data during the whole perioperative treatment process from various sources and provides it for risk identification and analysis in a centralized fashion. The results of such an analysis are provided to the medical personnel in form of context-sensitive hints and alerts. For the identification of the ontologically specified risks, we developed an ontology-based software module, called Ontology-based Risk Detector (OntoRiDe). About 20 risks relating to cochlear implantation (CI) have already been implemented. Comprehensive testing has indicated the correctness of the data acquisition, risk identification and analysis components, as well as the web-based visualization of results.

    The perioperative use and relevance of protective ventilation in surgical patients is being increasingly recognized. Obesity poses particular challenges to adequate mechanical ventilation in addition to surgical constraints, primarily by restricted lung mechanics due to excessive adiposity, frequent respiratory comorbidities (i.e. sleep apnea, asthma), and concerns of postoperative respiratory depression and other pulmonary complications. The number of surgical patients with obesity is increasing, and facing these challenges is common in the operating rooms and critical care units worldwide. In this review we summarize the existing literature which supports the following recommendations for the perioperative ventilation in obese patients: (1) the use of protective ventilation with low tidal volumes (approximately 8 mL/kg, calculated based on predicted -not actual- body weight) to avoid volutrauma; (2) a focus on lung recruitment by utilizing PEEP (8-15 cmH2O) in addition to recruitment maneuvers during the intraoperative period, as well as incentivized deep breathing and noninvasive ventilation early in the postoperative period, to avoid atelectasis, hypoxemia and atelectrauma; and (3) a judicious oxygen use (ideally less than 0.8) to avoid hypoxemia but also possible reabsorption atelectasis. Obesity poses an additional challenge for achieving adequate protective ventilation during one-lung ventilation, but different lung isolation techniques have been adequately performed in obese patients by experienced providers. Postoperative efforts should be directed to avoid hypoventilation, atelectasis and hypoxemia. Further studies are needed to better define optimum protective ventilation strategies and analyze their impact on the perioperative outcomes of surgical patients with obesity.

    Practice variation regarding perioperative antimicrobial prophylaxis in total artificial heart transplantations (TAH-t) across institutions is unknown. The aim of our survey was to assess the current practices for prevention of infection in TAH-t recipients among different programs. An electronic survey was sent to programs that implant Syncardia TAH (Syncardia Systems, Tuscon, Ariz, USA). Proportions were analyzed for categorical variables; means and SDs were analyzed for continuous variables. The majority of centers (80.8%) had a formal surgical infection prophylaxis protocol. For non-penicillin-allergic patients, five (20.1%) institutions reported using a 4-drug regimen, seven (29.2%) used a 3-drug regimen, five (20.1%) used a 2-drug regimen, and seven (29.2%) used a cephalosporin alone. Similar data was seen in the penicillin-allergic patients. Infections were reported to occur postoperatively in 52.2% centers. During the first month after TAH-t, bacteremia represented 27.3%, driveline infections 27.2%, pulmonary infections 9%, and mediastinal infections 18.2%. The most common organisms seen within the first month were Candida spp., Escherichia coli, and Pseudomonas aeruginosa (21.4%). In 65% of centers, the mean rate of death post-TAH-t due to infection was 14.5% (SD, 22.3%). The mean rate of patients surviving until orthotopic heart transplantation was 58.6% (SD, 27.7%). Preventing infections post-TAH-t is key to decreasing morbidity and mortality. All institutions administered perioperative prophylaxis for TAH-t with significant variation among the centers. The majority of the centers have a formal perioperative prophylactic protocol. Copyright © 2017. Published by Elsevier Inc.

    2014-06-01

    There is emerging evidence related to the effects of nitrous oxide on important perioperative patient outcomes. Proposed mechanisms include metabolic effects linked to elevated homocysteine levels and endothelial dysfunction, inhibition of deoxyribonucleic acid and protein formation, and depression of chemotactic migration by monocytes. Newer large studies point to possible risks associated with the use of nitrous oxide, although data are often equivocal and inconclusive. Cardiovascular outcomes such as stroke or myocardial infarction were shown to be unchanged in previous studies, but the more recent Evaluation of Nitrous Oxide in the Gas Mixture for Anesthesia I trial shows possible associations between nitrous oxide and increased cardiovascular and pulmonary complications. There are also possible effects on postoperative wound infections and neuropsychological function, although the multifactorial nature of these complications should be considered. Teratogenicity linked to nitrous oxide use has not been firmly established. The use of nitrous oxide for routine anesthetic care may be associated with significant costs if complications such as nausea, vomiting, and wound infections are taken into consideration. Overall, definitive data regarding the effect of nitrous oxide on major perioperative outcomes are lacking. There are ongoing prospective studies that may further elucidate its role. The use of nitrous oxide in daily practice should be individualized to each patient's medical conditions and risk factors.

    Full Text Available Background. Perioperative aneurysm rupture (PAR is one of the most dreaded complications of intracranial aneurysms, and approximately 80% of nontraumatic SAHs are related to such PAR aneurysms. The literature is currently scant and even controversial regarding the issues of various contributory factors on different phases of perioperative period. Thus this paper highlights the current understanding of various risk factors, variables, and outcomes in relation to PAR and try to summarize the current knowledge. Method. We have performed a PubMed search (1 January 1991–31 December 2012 using search terms including “cerebral aneurysm,” “intracranial aneurysm,” and “intraoperative/perioperative rupture.” Results. Various risk factors are summarized in relation to different phases of perioperative period and their relationship with outcome is also highlighted. There exist many well-known preoperative variables which are responsible for the highest percentage of PAR. The role of other variables in the intraoperative/postoperative period is not well known; however, these factors may have important contributory roles in aneurysm rupture. Preoperative variables mainly include natural course (age, gender, and familial history as well as the pathophysiological factors (size, type, location, comorbidities, and procedure. Previously ruptured aneurysm is associated with rupture in all the phases of perioperative period. On the other hand intraoperative/postoperative variables usually depend upon anesthesia and surgery related factors. Intraoperative rupture during predissection phase is associated with poor outcome while intraoperative rupture at any step during embolization procedure imposes poor outcome. Conclusion. We have tried to create such an initial categorization but know that we cannot scale according to its clinical importance. Thorough understanding of various risk factors and other variables associated with PAR will assist in better

    Increased airway hyperresponsiveness is a major concern in the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease. Guidelines using evidence-based medicine are continually being updated and published regarding the diagnosis, treatment, and prevention of these respiratory disorders. Perioperative management in these patients involves: (1) adequate control of airway hyperresponsiveness, including detection of purulent sputum and infection before surgery; (2) evidence-based control of anesthesia; and (3) the aggressive use of beta-2 adrenergic stimulants and the systemic administration of steroids for the treatment of acute attacks. Good preoperative control, including the use of leukotriene antagonists, can reduce the incidence of life-threatening perioperative complications. Awareness of recent guidelines is thus important in the management of patients with airway hyperresponsiveness. This review covers the most recent guidelines for the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease.

    : To investigate perioperative and postoperative bleeding, complications in patients under therapy with anticoagulant or antiplatelet drugs submitted to oral surgery. To evaluate the risk of bleeding and safety for dental surgery, a retrospective chart review was performed. Medical and dental records of patients taking oral antithrombotic drugs undergoing dental surgery between 2010 and 2015 were reviewed. Results were statistically analyzed using Fisher's exact test, t test or the χ test. One hundred and seventy-nine patients underwent 293 surgical procedures. A total of eight cases of perioperative and 12 episodes of postoperative bleeding were documented. The complications were generally managed with local measures and did not require hospitalization. We found significant association of postoperative hemorrhage with increased perioperative bleeding (P = 0.043) and combination of anticoagulant and antiplatelet therapy (P bleeding is 8.8 times bigger than procedures without perioperative bleeding. Dental surgery in patients under antithrombotic therapy might be carried out without altering the regimen because of low risk of perioperative and postoperative bleeding. However, patients with increased perioperative bleeding should be closely followed up because of postoperative complications risk.

    While there is substantial literature addressing the principles of general management of haemophilia, literature on perioperative management of haemostasis is scarce. The aim of this study was to better understand perioperative management among congenital haemophilia B patients (without inhibitors) and to gain insights into real-world surgical practices. A systematic literature review, with an emphasis on haemophilia B, was conducted using EMBASE ® , Medline ® and the Cochrane Library. Studies from 1974 to June 2015 were accessed, and 132 studies were eligible for the full-study review. An international expert panel with five haematologists and one surgeon reviewed the resulting literature and provided further insights. The literature review revealed that documented experience in the perioperative management of bleeding risk in haemophilia B patients is relatively scarce. Therefore, the review was amended to provide a comprehensive overview of the perioperative management for haemophilia A and B patients; the expert panel applied a particular focus to haemophilia B. Several gaps were identified in the literature including the lack of consensus on defining surgery in terms of bleeding risk, optimal factor levels during surgery and lack of robust evidence on surgical outcomes. The ensuing discussions with the expert panel provided validation of some of the results from the systematic literature review and proposed future directions for perioperative management. Suggestions included collaboration with haemophilia treatment centres (HTCs) to collect real-world data on perioperative management, establishing the need for optimal factor level monitoring practice, and the appropriate adoption of extended half-life products in clinical settings. © 2017 John Wiley & Sons Ltd.

    Background: Endovascular neurosurgery is known to be associated with potentially serious perioperative complications that can impact the course and outcome of anesthesia. We present here our institutional experience in the anesthetic management of various endovascular neurosurgical procedures and their related complications over a 10-year period. Methods: Data was obtained in 240 patients pertaining to their preoperative status, details of anesthesia and surgery, perioperative course and surgery-related complications. Information regarding hemodynamic alterations, temperature variability, fluid-electrolyte imbalance, coagulation abnormalities and alterations in the anesthesia course was specifically noted. Results: Among the important complications observed were aneurysm rupture (2.5%), vasospasm (6.67%), thromboembolism (4.16%), contrast reactions, hemodynamic alterations, electrolyte abnormalities, hypothermia, delayed emergence from anesthesia, groin hematomas and early postoperative mortality (5.14%). Conclusion: Awareness of the unique challenges of endovascular neurosurgery and prompt and appropriate management of the associated complications by an experienced neuroanesthesiologist is vital to the outcome of these procedures.

    2015-01-01

    Full Text Available Patients with pulmonary hypertension (PH are at high risk for complications in the perioperative setting and often receive vasodilators to control elevated pulmonary artery pressure (PAP. Administration of vasodilators via inhalation is an effective strategy for reducing PAP while avoiding systemic side effects, chiefly hypotension. The prototypical inhaled pulmonary-specific vasodilator, nitric oxide (NO, has a proven track record but is expensive and cumbersome to implement. Alternatives to NO, including prostanoids (such as epoprostenol, iloprost, and treprostinil, NO-donating drugs (sodium nitroprusside, nitroglycerin, and nitrite, and phosphodiesterase inhibitors (milrinone, sildenafil may be given via inhalation for the purpose of treating elevated PAP. This review will focus on the perioperative therapy of PH using inhaled vasodilators.

    Injection anaesthesia is commonly used in laboratory mice; however, a disadvantage is that post-anaesthesia recovery phases are long. Here, we investigated the potential for shortening the recovery phase after injection anaesthesia with fentanyl-midazolam-medetomidine by antagonization with naloxone-flumazenil-atipamezole. In order to monitor side-effects, the depth of anaesthesia, heart rate (HR), core body temperature (BT) and concentration of blood gases, as well as reflex responses, were assessed during a 50 min anaesthesia. Mice were allowed to recover from the anaesthesia in their home cages either with or without antagonization, while HR, core BT and spontaneous home cage behaviours were recorded for 24 h. Mice lost righting reflex at 330 ± 47 s after intraperitoneal injection of fentanyl-midazolam-medetomidine. During anaesthesia, HR averaged 225 ± 23 beats/min, respiratory rate and core BT reached steady state at 131 ± 15 breaths/min and 34.3 ± 0.25℃, respectively. Positive pedal withdrawal reflex, movement triggered by tail pinch and by toe pinch, still occurred in 25%, 31.2% and 100% of animals, respectively. Arterial blood gas analysis revealed acidosis, hypoxia, hypercapnia and a marked increase in glucose concentration. After anaesthesia reversal by injection with naloxone-flumazenil-atipamezole, animals regained consciousness after 110 ± 18 s and swiftly returned to physiological baseline values, yet they displayed diminished levels of locomotion and disrupted circadian rhythm. Without antagonization, mice showed marked hypothermia (22 ± 1.9℃) and bradycardia (119 ± 69 beats/min) for several hours. Fentanyl-midazolam-medetomidine provided reliable anaesthesia in mice with reasonable intra-anaesthetic side-effects. Post-anaesthetic period and related adverse effects were both reduced substantially by antagonization with naloxone-flumazenil-atipamezole. © The Author(s) 2016.

    Background Dexamethasone has been studied as an effective adjuvant to prolong the analgesia duration of local anesthetics in peripheral nerve block. However, the route of action for dexamethasone and its potential neurotoxicity are still unclear. Methods A mouse sciatic nerve block model was used. The sciatic nerve was injected with 60ul of combinations of various medications, including dexamethasone and/or bupivacaine. Neurobehavioral changes were observed for 2 days prior to injection, and then continuously for up to 7 days after injection. In addition, the sciatic nerves were harvested at either 2 days or 7 days after injection. Toluidine blue dyeing and immunohistochemistry test were performed to study the short-term and long-term histopathological changes of the sciatic nerves. There were six study groups: normal saline control, bupivacaine (10mg/kg) only, dexamethasone (0.5mg/kg) only, bupivacaine (10mg/kg) combined with low-dose (0.14mg/kg) dexamethasone, bupivacaine (10mg/kg) combined with high-dose (0.5mg/kg) dexamethasone, and bupivacaine (10mg/kg) combined with intramuscular dexamethasone (0.5mg/kg). Results High-dose perineural dexamethasone, but not systemic dexamethasone, combined with bupivacaine prolonged the duration of both sensory and motor block of mouse sciatic nerve. There was no significant difference on the onset time of the sciatic nerve block. There was “rebound hyperalgesia” to thermal stimulus after the resolution of plain bupivacaine sciatic nerve block. Interestingly, both low and high dose perineural dexamethasone prevented bupivacaine-induced hyperalgesia. There was an early phase of axon degeneration and Schwann cell response as represented by S-100 expression as well as the percentage of demyelinated axon and nucleus in the plain bupivacaine group compared with the bupivacaine plus dexamethasone groups on post-injection day 2, which resolved on post-injection day 7. Furthermore, we demonstrated that perineural dexamethasone

    Full Text Available Postural orthostatic tachycardia syndrome (POTS is a disorder characterized by postural tachycardia in combination with orthostatic symptoms without associated hypotension. Symptoms include light-headedness, palpitations, fatigue, confusion, and anxiety, which are brought on by assuming the upright position and usually relieved by sitting or lying down. Given the associated autonomic dysfunction that occurs with POTS, various perioperative concerns must be considered when providing anesthetic care for such patients. We present an adolescent with POTS who required anesthetic care during posterior spinal fusion for the treatment of scoliosis. The potential perioperative implications of this syndrome are discussed.

    Full Text Available Objectives. To investigate the efficacy and safety of perioperative endocrine therapy (PET for patients with Cushing’s syndrome (CS undergoing retroperitoneal laparoscopic adrenalectomy (RLA. Methods. The novel, simplified PET modality of 82 patients who underwent RLA procedures for CS were studied. Clinical manifestations were observed for all patients on days 1 and 5 postoperatively, and clinical data, such as blood pressure (BP, levels of serum cortisol, adrenocorticotropin (ACTH, blood glucose, and electrolytes, were acquired and analyzed. Results. Supraphysiological doses of glucocorticoid were administered during the perioperative period, and the dosage was reduced gradually. In all 82 cases, the RLAs were performed successfully without any perioperative complication, such as steroid withdrawal symptoms. The patient’s symptoms and signs were improved quickly and safely during the hospital days. The serum cortisol and potassium levels were rather stable on days 1 and 5 postoperatively, and most were within the normal range. The clinical manifestations, serum levels of cortisol, ACTH, and potassium in most patients restored to normal gradually after several months (mean, 6.7 ± 1.2 months, except for one patient undergoing bilateral adrenalectomy. Conclusions. This perioperative endocrine therapy for patients with Cushing’s syndrome (mainly for adrenocortical adenoma undergoing retro-laparoscopic adrenalectomy is both effective and safe.

  17. Perioperative thirst: an analysis from the perspective of the Symptom Management Theory

    Directory of Open Access Journals (Sweden)

    Marilia Ferrari Conchon

    2015-02-01

    Full Text Available A theoretical study aimed to analyze the existing knowledge in the literature on the perioperative thirst symptom from the perspective of Symptom Management Theory, and supplemented with the experience of the study group and thirst research. Thirst is described as a very intense symptom occurring in the perioperative period, and for this reason it cannot be ignored. The Symptom Management Theory is adequate for understanding the thirst symptom and is a deductive theory, focused on the domains of the Person, Environment and Health / Illness Status, as well as on the dimensions of Experience, Management Strategies and Symptom Outcomes. Using the theory leads us to consider perioperative thirst in its multifactorial aspects, analyzing the interrelation of its domains and dimensions in order to draw attention to this symptom that has been insufficiently valued, recorded and treated in clinical practice.

    The World Health Organization sets a standard to maintain patient core temperature greater than 36°C throughout the perioperative period. Normothermia (defined as >36°C) in the Operating Room (OR) is an important factor to preventing complications in patients (MI, infection, coagulopathy). Randomized studies suggests that maintaining at higher temperatures may further reduce complications in surgery (less complications for group at 36.4°C than the control group at 36.0°C) [1,2]. Perioperative normothermia is an important but often unrecognized element during anesthesia. Early recognition of hypothermia would allow for appropriate interventions and prevent complications. Manual validation of the diagnostic performance a clinical tool (alert) that would automatically measure changes in core temperature to identify patients who fail to be in range of normothermia during surgery. The clinical tool (alert) was found to be 97 % sensitive.

    Perineural invasion (PNI) is correlated with adverse survival in several malignancies, but its significance in esophageal squamous cell carcinoma (ESCC) remains to be clearly defined. The objective of this study was to determine the association between PNI status and clinical outcomes. We retrospectively evaluated the PNI of 433 patients with ESCC treated with surgery between 2000 and 2007 at a single academic center. The resulting data were analyzed using Spearman’s rank correlation, the Kaplan-Meier method, Cox proportional hazards regression modeling and Harrell’s concordance index (C-index). PNI was identified in 209 of the 433 (47.7%) cases of ESCC. The correlation analysis demonstrated that PNI in ESCC was significantly correlated with tumor differentiation, infiltration depth, pN classification and stage (P < 0.05). The five-year overall survival rate was 0.570 for PNI-negative tumors versus 0.326 for PNI-positive tumors. Patients with PNI-negative tumors exhibited a 1.7-fold increase in five-year recurrence-free survival compared with patients with PNI-positive tumors (0.531 v 0.305, respectively; P < 0.0001). In the subset of patients with node-negative disease, PNI was evaluated as a prognostic predictor as well (P < 0.05). In the multivariate analysis, PNI was an independent prognostic factor for overall survival (P = 0.027). The C-index estimate for the combined model (PNI, gender and pN status) was a significant improvement on the C-index estimate of the clinicopathologic model alone (0.739 v 0.706, respectively). PNI can function as an independent prognostic factor of outcomes in ESCC patients, and the PNI status in primary ESCC specimens should be considered for therapy stratification

    Levosimendan is a calcium sensitizer drug causing increased contractility in the myocardium and vasodilation in the vascular system. It is mainly used for the therapy of acute decompensated heart failure. Several studies on animals and humans provided evidence of the cardioprotective properties of levosimendan including preconditioning and anti-apoptotic. In view of these favorable effects, levosimendan has been tested in patients undergoing cardiac surgery for the prevention or treatment of low cardiac output syndrome. However, initial positive results from small studies have not been confirmed in three recent large trials. To summarize levosimendan mechanisms of action and clinical use and to review available evidence on its perioperative use in cardiac surgery setting. We searched two electronic medical databases for randomized controlled trials studying levosimendan in cardiac surgery patients, ranging from January 2000 to August 2017. Meta-analyses, consensus documents and retrospective studies were also reviewed. In the selected interval of time, 54 studies on the use of levosimendan in heart surgery have been performed. Early small size studies and meta-analyses have suggested that perioperative levosimendan infusion could diminish mortality and other adverse outcomes (i.e. intensive care unit stay and need for inotropic support). Instead, three recent large randomized controlled trials (LEVO-CTS, CHEETAH and LICORN) showed no significant survival benefits from levosimendan. However, in LEVO-CTS trial, prophylactic levosimendan administration significantly reduced the incidence of low cardiac output syndrome. Based on most recent randomized controlled trials, levosimendan, although effective for the treatment of acute heart failure, can't be recommended as standard therapy for the management of heart surgery patients. Further studies are needed to clarify whether selected subgroups of heart surgery patients may benefit from perioperative levosimendan

    Purpose: Evaluation of the results of perioperative interstitial brachytherapy with low dose-rate (L.D.R.) Ir-192 in the treatment of keloid scars. Patients and methods: We performed a retrospective analysis of 73 histologically confirmed keloids (from 58 patients) resistant to medico surgical treated by surgical excision plus early perioperative brachytherapy. All lesions were initially symptomatic. Local control was evaluated by clinical evaluation. Functional and cosmetic results were assessed in terms of patient responses to a self-administered questionnaire. Results: Median age was 28 years (range 13-71 years). Scars were located as follows: 37% on the face, 32% on the trunk or abdomen, 16% on the neck, and 15% on the arms or legs. The mean delay before loading was four hours (range, 1-6 h). The median dose was 20 Gy (range, 15-40 Gy). Sixty-four scars (from 53 patients) were evaluated. Local control was 86% (follow-up, 44.5 months; range, 14-150 months). All relapses occurred early within 2 years posttreatment. At 20 months, survival without recurrence was significantly lower when treated lengths were more than 6 cm long. The rate was 100% for treated scars below 4.5 cm in length, 95% (95% CI: 55-96) for those 4.5-6 cm long, and 75% (95% CI: 56-88) beyond 6 cm (p = 0.038). Of the 35 scars (28 patients) whose results were reassessed, six remained symptomatic and the esthetic results were considered to be good in 51% (18/35) and average in 37% (13/35) (median follow-up, 70 months; range, 16-181 months). Conclusion: Early perioperative L.D.R. brachytherapy delivering 20 Gy at 5 mm reduced the rate of recurrent keloids resistant to other treatments and gave good functional results. (authors)

    Nutritional status of patients significantly affects the outcome of surgical treatment, whether it's about being obese or malnutrition with loss of muscle mass. Inadequate nutritional support in the perioperative period compromises surgical procedures even in patients who are adequately nourished. In this paper, particular attention was paid to malnourished patients, and their incidence in population hospitalized in surgical wards can be high up to 30%. Special emphasis was paid to the appropriateness of preoperative fasting and to the acceptance of new knowledge in this area of treatment. The aim of this working group was to make guidelines for perioperative nutritional support with different modalities of enteral nutrition. The development of these guidelines was attended by representatives of Croatian Medical Association: Croatian Society for Digestive Surgery, Croatian Society for Clinical Nutrition, Croatian Society of Surgery, Croatian Society for Endoscopic Surgery, Croatian Trauma Society and the Croatian Society of Anesthesiology and Intensive Care. The guidelines are designed as a set of questions that arise daily in clinical practice when preparing patients for surgery and after the surgical treatment, which relate to the assessment of nutritional status, perioperative nutritional support, duration of preoperative fasting period and the selection of food intake route. Assessment of nutritional status and the use of different modes of enteral nutrition should enter into standard protocols of diagnosis and treatment in the Croatian hospitals.

    We investigated the risk factor of perioperative asthmatic attack and effectiveness of preventing treatment for asthmatic attack before operation. We performed retrospective chart review of one hundred eleven patients with asthma underwent general anesthesia and surgical intervention from January 2006 to October 2007 in our hospital. The rate of perioperative asthmatic attack were as follows; 10.2% (5 in 49 cases) in no pretreatment group, 7.5% (3 in 40 cases) in any pretreatments except for systemic steroid, and 4.5% (1 in 22 cases) in systemic steroid pretreatment group. Neither preoperative asthma severity nor duration from the last attack had significant relevancy to perioperative attack rate. The otolaryngological surgery, especially those have nasal polyp and oral surgery had high perioperative asthma attack rate, although there was no significant difference. We recommend the systemic steroid pretreatment for asthmatic patients, especially when they have known risk factor such as administration of the systemic steroid within 6 months, or possibly new risk factor such as nasal polyp, otolaryngological and oral surgery.

    In the hospital, fast and efficient communication among clinicians and other employees is paramount to ensure optimal patient care, workflow efficiency, patient safety and patient comfort. The implementation of the wireless Vocera® Badge, a hands-free wearable device distributed to perioperative team members, has increased communication efficiency across the perioperative environment at Massachusetts General Hospital (MGH). This quality improvement project, based upon identical pre- and post-implementation surveys, used qualitative and quantitative analysis to determine if and how the Vocera system affected the timeliness of information flow, ease of communication, and operating room noise levels throughout the perioperative environment. Overall, the system increased the speed of information flow and eased communication between coworkers yet was perceived to have raised the overall noise level in and around the operating rooms (ORs). The perceived increase in noise was outweighed by the closed-loop communication between clinicians. Further education of the system's features in regard to speech recognition and privacy along with expected conversation protocol are necessary to ensure hassle-free communication for all staff.

    Gualtierotti, Roberta; Parisi, Marco; Ingegnoli, Francesca

    2018-04-01

    Patients with inflammatory rheumatic diseases often need orthopaedic surgery due to joint involvement. Total hip replacement and total knee replacement are frequent surgical procedures in these patients. Due to the complexity of the inflammatory rheumatic diseases, the perioperative management of these patients must envisage a multidisciplinary approach. The frequent association with extraarticular comorbidities must be considered when evaluating perioperative risk of the patient and should guide the clinician in the decision-making process. However, guidelines of different medical societies may vary and are sometimes contradictory. Orthopaedics should collaborate with rheumatologists, anaesthesiologists and, when needed, cardiologists and haematologists with the common aim of minimising perioperative risk in patients with inflammatory rheumatic diseases. The aim of this review is to provide the reader with simple practical recommendations regarding perioperative management of drugs such as disease-modifying anti-rheumatic drugs, corticosteroids, non-steroidal anti-inflammatory drugs and tools for a risk stratification for cardiovascular and thromboembolic risk based on current evidence for patients with inflammatory rheumatic diseases.

  10. The Role of Emotional Intelligence in Perioperative Nursing and Leadership: Developing Skills for Improved Performance.

    Science.gov (United States)

    Beydler, Kathy Williams

    2017-10-01

    Many responsibilities of perioperative professionals involve concrete tasks that require high technical competence. Emotional intelligence, referred to as EQ, which involves the ability to relate to and influence others, may also be important for perioperative professionals. High EQ has been linked to higher performance in the workplace, higher job satisfaction, lower turnover intentions, and less burnout. Perioperative professionals who demonstrate a combination of technical skills and EQ could be more attuned to the humanity of health care (ie, providing more holistic care for the patient). Perioperative nurses who value providing holistic care for their patients may possess many of the elements of EQ. Leaders who recognize the importance of their own EQ and actively assist staff members to enhance and develop their EQ competency may help to create a competitive advantage by establishing a workforce of nurses who possess strong technical skills and high EQ.

    2010-01-01

    Perioperative cardiac arrests and death on the table represent the most serious complications of surgery and anaesthesia. This paper was designed to study their pattern, causes and outcomes following cardiopulmonary resuscitation (CPR) and intensive care unit (ICU) management in our institution. Three year retrospective review of perioperative cardiac arrests and death on operating table following surgical procedure under anaesthesia. For each cardiac arrest or death on the table the sequence of events leading to the arrest was evaluated using case notes, anaesthetic chart and ICU records. Study variables which include demographic data, ASA score, anaesthetic technique, causes and outcome were analysed and discussed. Fourteen perioperative cardiac arrests were encountered following 4051 anaesthetics administered over the three year study period. Twelve out of the fourteen cardiac arrests occurred following general anaesthesia, while the remaining two occurred following spinal anaesthesia. There was no cardiac arrest following local anaesthesia. Children suffered more cardiac arrest than adults. ASA class III and IV risk status suffered more arrests than ASA I and II. Hypoxia from airway problems was the commonest cause of cardiac arrest followed by septic shock. Monitoring with pulse oximeter was done in only 4 out of the 14 cardiac arrests. Only 2 (14%) out of 14 cardiac arrests recovered to home discharge, one of them with significant neurological deficit. Majority of arrests were due to hypoxia from airway problems that were not detected early There is need to improve on patient monitoring, knowledge of CPR and intensive care so as to improve the outcome of perioperative cardiac arrest.

    This review of the literature since 2005 assesses developments of RA techniques commonly used for shoulder surgery, and their effectiveness for postoperative analgesia. Advantages of regional techniques include site-specific anesthesia and decreased postoperative opioid use. For shoulder surgeries, the ISB provides effective analgesia with minimal complications, whereas the impacts of IA single-injections remain unclear. When combined with GA, ISB can be used in lower volumes and reducing the complications for shoulder and proximal upper extremity. USG ISB and SCB are both effective and safe for shoulder surgery with a low incidence of complications, especially PONS.53 When compared with intravenous patient-controlled opioid analgesia, a perineural LA infusion using a disposable pump with patient-controlled LA bolus function has led to better pain relief and functional recovery while decreasing the need for rescue analgesics and the number of adverse events after ambulatory orthopedic surgery. The most remarkable advance in RA in the past 5 years is the increased usage of USG. Although there are no large-scale prospective studies to show the safety, efficacy, and success and complication rates for USG blocks, USG RA theoretically could have less risk for neurologic symptoms, except for those induced by LA (less likely perineurally, much more likely intraneurally). The next "quantum leap" lies in reducing LA concentrations and augmenting anesthetic-analgesic effects with perineural additives (including clonidine, buprenorphine, and likely low-dose dexamethasone). Since 2005, perineural catheters have been an analgesic option that offers improved pain relief among other benefits, and are now being used at home. It is clear that patients benefit greatly from a single injection and continuous nerve block for postoperative pain management,but the financial and logistical aspects need to be resolved, not to mention the phrenic hemiparesis coin toss.

    The innovative Perioperative Surgical Home model aims to optimize the outcomes of surgical patients by leveraging the expertise and leadership of physician anesthesiologists, but there is a paucity of practical examples to follow. Veterans Affairs health care, the largest integrated system in the United States, may be the ideal environment in which to explore this model. We present our experience implementing Perioperative Surgical Home at one tertiary care university-affiliated Veterans Affairs hospital. This process involved initiating consistent postoperative patient follow-up beyond the postanesthesia care unit, a focus on improving in-hospital acute pain management, creation of an accessible database to track outcomes, developing new clinical pathways, and recruiting additional staff. Today, our Perioperative Surgical Home facilitates communication between various services involved in the care of surgical patients, monitoring of patient outcomes, and continuous process improvement. © The Author(s) 2015.

    2010-01-01

    Full Text Available Laryngotracheal reconstruction (LTR involves surgical correction of a stenotic airway with cartilage interpositional grafting, followed by either placement of a tracheostomy and an intraluminal stent (two-stage LTR or placement of an endotracheal tube with postoperative sedation and mechanical ventilation for an extended period of time (single-stage LTR. With single-stage repair, there may be several perioperative challenges including the provision of adequate sedation, avoidance of the development of tolerance to sedative and analgesia agents, the need to use neuromuscular blocking agents, the maintenance of adequate pulmonary toilet to avoid perioperative nosocomial infections, and optimization of postoperative respiratory function to facilitate successful tracheal extubation. We review the perioperative management of these patients, discuss the challenges during the postoperative period, and propose recommendations for the prevention of reversible causes of extubation failure in this article. Optimization to ensure a timely tracheal extubation and successful weaning of mechanical ventilator, remains the primary key to success in these surgeries as extubation failure or the need for prolonged postoperative mechanical ventilation can lead to failure of the graft site, the need for prolonged Pediatric Intensive Care Unit care, and in some cases, the need for a tracheostomy to maintain an adequate airway.

    Extraction of data from the electronic medical record is becoming increasingly important for quality improvement initiatives such as the American Society of Anesthesiologists Perioperative Surgical Home. To meet this need, the authors have built a robust and scalable data mart based on their implementation of EPIC containing data from across the perioperative period. The data mart is structured in such a way so as to first simplify the overall EPIC reporting structure into a series of Base Tables and then create several Reporting Schemas each around a specific concept (operating room cases, obstetrics, hospital admission, etc.), which contain all of the data required for reporting on various metrics. This structure allows centralized definitions with simplified reporting by a large number of individuals who access only the Reporting Schemas. In creating the database, the authors were able to significantly reduce the number of required table identifiers from >10 to 3, as well as to correct errors in linkages affecting up to 18.4% of cases. In addition, the data mart greatly simplified the code required to extract data, making the data accessible to individuals who lacked a strong coding background. Overall, this infrastructure represents a scalable way to successfully report on perioperative EPIC data while standardizing the definitions and improving access for end users.

    It is established that blood transfusions will promote sensitization to human leucocyte antigen (HLA) antigens, increase time spent waiting for transplantation and may lead to higher rates of rejection. Less is known about how perioperative blood transfusion influence patient and graft outcome. This study aims to establish if there is an association between perioperative blood transfusion and graft or patient survival.

    2018-02-01

    To develop and validate a radiomics prediction model for individualized prediction of perineural invasion (PNI) in colorectal cancer (CRC). After computed tomography (CT) radiomics features extraction, a radiomics signature was constructed in derivation cohort (346 CRC patients). A prediction model was developed to integrate the radiomics signature and clinical candidate predictors [age, sex, tumor location, and carcinoembryonic antigen (CEA) level]. Apparent prediction performance was assessed. After internal validation, independent temporal validation (separate from the cohort used to build the model) was then conducted in 217 CRC patients. The final model was converted to an easy-to-use nomogram. The developed radiomics nomogram that integrated the radiomics signature and CEA level showed good calibration and discrimination performance [Harrell's concordance index (c-index): 0.817; 95% confidence interval (95% CI): 0.811-0.823]. Application of the nomogram in validation cohort gave a comparable calibration and discrimination (c-index: 0.803; 95% CI: 0.794-0.812). Integrating the radiomics signature and CEA level into a radiomics prediction model enables easy and effective risk assessment of PNI in CRC. This stratification of patients according to their PNI status may provide a basis for individualized auxiliary treatment.

    Purpose: To review the factors that influence outcome and patterns of relapse in patients with cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) with perineural infiltration (PNI) without clinical or radiologic features, treated with surgery and radiotherapy. Methods and Materials: Between 1991 and 2004, 222 patients with SCC or BCC with PNI on pathologic examination but without clinical or radiologic PNI features were identified. Charts were reviewed retrospectively and relevant data collected. All patients were treated with curative intent; all had radiotherapy, and most had surgery. The primary endpoint was 5-year relapse-free survival from the time of diagnosis. Results: Patients with SCC did significantly worse than those with BCC (5-year relapse-free survival, 78% vs. 91%; p < 0.01). Squamous cell carcinoma with PNI at recurrence did significantly worse than de novo in terms of 5-year local failure (40% vs. 19%; p < 0.01) and regional relapse (29% vs. 5%; p < 0.01). Depth of invasion was also a significant factor. Of the PNI-specific factors for SCC, focal PNI did significantly better than more-extensive PNI, but involved nerve diameter or presence of PNI at the periphery of the tumor were not significant factors. Conclusions: Radiotherapy in conjunction with surgery offers an acceptable outcome for cutaneous SCC and BCC with PNI. This study suggests that focal PNI is not an adverse feature.

    Accurate definition of the presence and extent of large nerve perineural spread (PNS) is a vital component in planning appropriate surgery and radiotherapy for head and neck cancers. Our research aimed to define the sensitivity and specificity of 3T MRI in detecting the presence and extent of large nerve PNS, compared with histologic evaluation. Retrospective review of surgically proven cases of large nerve PNS in patients with preoperative 3T MRI performed as high resolution neurogram. 3T MRI had a sensitivity of 95% and a specificity of 84%, detecting PNS in 36 of 38 nerves and correctly identifying uninvolved nerves in 16 of 19 cases. It correctly identified the zonal extent of spread in 32 of 36 cases (89%), underestimating the extent in three cases and overestimating the extent in one case. Targeted 3T MRI is highly accurate in defining the presence and extent of large nerve PNS in head and neck cancers. However, there is still a tendency to undercall the zonal extent due to microscopic, radiologically occult involvement. Superficial large nerve involvement also remains a difficult area of detection for radiologists and should be included as a 'check area' for review. Further research is required to define the role radiation-induced neuritis plays in the presence of false-positive PNS on MRI. © 2015 The Royal Australian and New Zealand College of Radiologists.

    Blood transfusion is linked to a negative outcome for malignant tumors. The aim of this study was to evaluate aggressive surgical resection for hilar cholangiocarcinoma (HCCA) and assess the impact of perioperative blood transfusion on long-term survival. Sixty-six consecutive major hepatectomies with en bloc resection of the caudate lobe and extrahepatic bile duct for HCCA were performed using macroscopically curative resection at our institute from 2002 to 2012. Clinicopathologic factors for recurrence and survival were retrospectively assessed. Overall survival rates at 1, 3, and 5 years were 86.7, 47.3, and 35.7 %, respectively. In univariate analysis, perioperative blood transfusion and a histological positive margin were two of several variables found to be significant prognostic factors for recurrence or survival (Pblood transfusion was independently associated with recurrence (hazard ratio (HR)=2.839 (95 % confidence interval (CI), 1.370-5.884), P=0.005), while perioperative blood transfusion (HR=3.383 (95 % CI, 1.499-7.637), P=0.003) and R1 resection (HR=3.125 (95 % CI, 1.025-9.530), P=0.045) were independent risk factors for poor survival. Perioperative blood transfusion is a strong predictor of poor survival after radical hepatectomy for HCCA. We suggest that circumvention of perioperative blood transfusion can play an important role in long-term survival for patients with HCCA.

    Treating surgical complications presents a major challenge for hospitals striving to deliver high-quality care while reducing costs. Costs associated with rescuing patients from perioperative complications are poorly characterized. To evaluate differences across hospitals in the costs of care for patients surviving perioperative complications after major inpatient surgery. Retrospective cohort study using claims data from the Medicare Provider Analysis and Review files. We compared payments for patients who died vs patients who survived after perioperative complications occurred. Hospitals were stratified using average payments for patients who survived following complications, and payment components were analyzed across hospitals. Administrative claims database of surgical patients was analyzed at hospitals treating Medicare patients nationwide. This study included Medicare patients aged 65 to 100 years who underwent abdominal aortic aneurysm repair (n = 69 207), colectomy for cancer (n = 107 647), pulmonary resection (n = 91 758), and total hip replacement (n = 307 399) between 2009 and 2012. Data analysis took place between November 2015 and March 2016. Clinical outcome of surgery (eg, no complication, complication and death, or complication and survival) and the individual hospital where a patient received an operation. Risk-adjusted, price-standardized Medicare payments for an episode of surgery. Risk-adjusted perioperative outcomes were also assessed. The mean age for Medicare beneficiaries in this study ranged from 74.1 years (pulmonary resection) to 78.2 years (colectomy). The proportion of male patients ranged from 37% (total hip replacement) to 77% (abdominal aortic aneurysm repair), and most patients were white. Among patients who experienced complications, those who were rescued had higher price-standardized Medicare payments than did those who died for all 4 operations. Assessing variation across hospitals, payments for patients

    To compare perioperative outcomes of robot-assisted partial nephrectomy (RAPN) for hilar vs nonhilar tumors. The study retrospectively reviewed 364 patients with available computed tomography scans undergoing RAPN. Demographic data and perioperative outcomes results were compared between the hilar (group 1, n = 70) and nonhilar tumors (group 2, n = 294). Multivariate analysis was used to identify predictors of warm ischemia time (WIT), estimated blood loss (EBL), major perioperative complications, and postoperative renal function. There were no differences with respect to demographic variables. Hilar tumors had higher RENAL (radius, exophytic/endophytic properties of the tumor, nearness of tumor deepest portion to the collecting system or sinus, anterior/posterior descriptor and the location relative to polar lines) scores (P hilar tumors were associated with greater operative time (210 vs 180 minutes, P hilar vs nonhilar patients on postoperative day 3 (70.12 vs 74.71 mL/min/1.73 m(2), P = .31) or at last follow-up (72.62 vs 75.78 mL/min/1.73 m(2), P = .40), respectively. Multivariate analysis found hilar location was independently associated with increased WIT without significant changes in EBL, major complications, or postoperative renal function. RAPN represents a safe and effective procedure for hilar tumors. Hilar location for patients undergoing RAPN in a high-volume institution seems not be associated with an increased risk of transfusions, major complications, or decline of early postoperative renal function.

    Full Text Available Modern surgery is faced with the emergence of newer “risk factors” and the challenges associated with identifying and managing these risks in the perioperative period. Obstructive sleep apnea and obesity hypoventilation syndrome pose unique challenges in the perioperative setting. Recent studies have identified some of the specific risks arising from caring for such patients in the surgical setting. While all possible postoperative complications are not yet fully established or understood, the prevention and management of these complications pose even greater challenges. Pulmonary hypertension with its changing epidemiology and novel management strategies is another new disease for the surgeon and the anesthesiologist in the noncardiac surgical setting. Traditionally most such patients were not considered surgical candidates for any required elective surgery. Our review discusses these disease entities which are often undiagnosed before elective noncardiac surgery.

    To develop 2 instruments that predict the probability of perioperative red blood cell transfusion in patients undergoing elective liver resection for primary and secondary tumors. Hepatic resection is the most effective treatment for several benign and malign conditions, but may be accompanied by substantial blood loss and the need for perioperative transfusions. While blood conservation strategies such as autologous blood donation, acute normovolemic hemodilution, or cell saver systems are available, they are economically efficient only if directed toward patients with a high risk of transfusion. Using preoperative data from 1204 consecutive patients who underwent liver resection between 1995 and 2000 at Memorial Sloan- Kettering Cancer Center, we modeled the probability of perioperative red blood cell transfusion. We used the resulting model, validated on an independent dataset (n = 555 patients), to develop 2 prediction instruments, a nomogram and a transfusion score, which can be easily implemented into clinical practice. The planned number of liver segments resected, concomitant extrahepatic organ resection, a diagnosis of primary liver malignancy, as well as preoperative hemoglobin and platelets levels predicted the probability of perioperative red blood cell transfusion. The predictions of the model appeared accurate and with good discriminatory abilities, generating an area under the receiver operating characteristic curve of 0.71. Preoperative factors can be combined into risk profiles to predict the likelihood of transfusion during or after elective liver resection. These predictions, easy to calculate in the frame of a nomogram or of a transfusion score, can be used to identify patients who are at high risk for red cell transfusions and therefore most likely to benefit from blood conservation techniques.

    In recent years, operating theatre nurse students' education focussed on ethical value issues and how the patient's dignity is respected in the perioperative practice. Health professionals are frequently confronted with ethical issues that can impact on patient's care during surgery. The objective of this study was to present what operating theatre nurse students experienced and interpreted as preserved dignity in perioperative practice. The study has a descriptive design with a hermeneutic approach. Data were collected using Flanagan's critical incident technique. Operating theatre nurse students from Sweden and Norway participated and collected data in 2011, after education in ethics and dignity. Data consisting of 47 written stories and the text were analysed with hermeneutical text interpretation. The study was conducted accordance with the Declaration of Helsinki and approved by a local University Ethics Research Committee. The findings revealed that students experienced that operating theatre nurses perserved patient's dignity in perioperative practice by being present for each other and making themselves known to the patient. Operating theatre nurses caring for the patient by being compassionate and preserved the patient privacy. The new understanding that emerged was that the operating theatre nurse students understood that the operating theatre nurse wanted to care for the patient like a human being. In the discussion, we have illuminated how professional ethics may be threatened by more pragmatic and utilitarian arguments contained in regulations and transplant act. Preserved dignity is an ethical and caring act. Ethical questions and how to preserve dignity in perioperative practice should be discussed more both in educations of healthcare professionals and in clinical practice. © The Author(s) 2014.

    Multi-organ procurement surgical procedures through the generosity of deceased organ donors, have made an enormous impact on extending the lives of recipients. There is a dearth of in-depth knowledge relating to the experiences of perioperative nurses working closely with organ donors undergoing multi-organ procurement surgical procedures. The aim of this study was to address this gap by describing the perioperative nurses experiences of participating in multi-organ procurement surgical procedures and interpreting these findings as a substantive theory. This qualitative study used grounded theory methodology to generate a substantive theory of the experiences of perioperative nurses participating in multi-organ procurement surgery. Recruitment of participants took place after the study was advertised via a professional newsletter and journal. The study was conducted with participants from metropolitan, rural and regional areas of two Australian states; New South Wales and Western Australia. Thirty five perioperative nurse participants with three to 39 years of professional nursing experience informed the study. Semi structured in-depth interviews were undertaken from July 2009 to April 2010 with a mean interview time of 60 min. Interview data was transcribed verbatim and analysed using the constant comparative method. The study results draw attention to the complexities that exist for perioperative nurses when participating in multi-organ procurement surgical procedures reporting a basic social psychological problem articulated as hiding behind a mask and how they resolved this problem by the basic social psychological process of finding meaning. This study provides a greater understanding of how these surgical procedures impact on perioperative nurses by providing a substantive theory of this experience. The findings have the potential to guide further research into this challenging area of nursing practice with implications for clinical initiatives, management

    Conclusions: Surgical case order may influence perioperative outcomes for RARP with decreased operative times and increased length of hospital stay associated with later cases. These findings indicate that select perioperative factors may improve with ascending case order as the surgical team "warms up" during the day. In addition, 3 rd round cases can increase hospital costs associated with increased lengths of hospital stay. Knowledge of these differences may assist in surgical planning to improve outcomes and limit costs.

    Full Text Available Optimization of the pharmacotherapy in preoperative period is the cornerstone of the concept of risk modification of cardiovascular complications in the perioperative period. Therefore, special attention has recently been focused on the use of beta-blockers in the postoperative period. Nowadays convincing evidence base for the use of this class of drugs in the perioperative period that was the basis for the development of clinical guidelines is accumulated. Moreover, results of large randomized trials of beta-blockers are controversial. This has resulted in significant differences in the classes of recommendations and levels of evidence.Analysis of the results of basic researches and the provisions of recommendations of the international and national professional medical societies on the use of beta-blockers in patients with cardiovascular disease to reduce the risk of cardiac complications in the perioperative period for planned extracardiac surgical procedures is presented.

Its feasibility, safety, and efficacy have already been clinically demonstrated in patients with multiple rib fractures using higher volumes of local anesthetic, when compared with the traditional approach. The primary aim of this observational anatomical study was to assess the spread of local anesthetic from the retrolaminar injection point to the PV space and its volume dependence. Second, we assessed the incidence of epidural and contralateral PV spread in the both groups.Methods: Ten fresh porcine cadavers were randomized into 2 groups (n=5 each to receive ultrasound-guided retrolaminar injections at Th4-Th5 level with either 10 mL (low-volume group or 30 mL (high-volume group of 2% lidocaine and methylene blue mixture. After the procedure, the cadavers were dissected and frozen. Cross-section cuts (~1 cm thick were performed to evaluate the injectate spread.Results: In the high-volume group, injectate spread from the retrolaminar to the PV space was observed in all specimens (5 out of 5; 100%, while in the low-volume group, no apparent spread to the PV space was found (0 out of 5; 0%. No epidural or contralateral PV spread was observed in any of the specimens.Conclusion: Following ultrasound-guided retrolaminar injections in fresh porcine cadavers, injectate spread from the retrolaminar tissue plane to the PV space is strongly volume dependent

    To determine current practice for use of perioperative antibiotics among facial plastic surgeons, to determine the extent of use of literature support for preferences of facial plastic surgeons, and to compare patterns of use with nationally supported evidence-based guidelines. A link to a Web site containing a questionnaire on perioperative antibiotic use was e-mailed to more than 1000 facial plastic surgeons in the United States. Responses were archived in a dedicated database and analyzed to determine patterns of use and methods of documenting that use. Current literature was used to develop evidence-based recommendations for perioperative antibiotic use, emphasizing current nationally supported guidelines. Preferences varied significantly for medication used, dosage and regimen, time of first dose relative to incision time, setting in which medication was administered, and procedures for which perioperative antibiotic was deemed necessary. Surgical site infection in facial plastic surgery can be reduced by better conformance to currently available evidence-based guidelines. We offer specific recommendations that are supported by the current literature.

    Perioperative nurses assist in organ procurement surgery; however, there is a dearth of information of how they encounter making conscientious objection requests or refusals to participate in organ procurement surgery. Organ procurement surgical procedures can present to the operating room ad hoc and can catch a nurse who may not desire to participate by surprise with little opportunity to refuse as a result of staffing, skill mix or organizational work demands. This paper that stems from a larger doctoral research study exploring the experiences of perioperative nurses participating in multi-organ procurement surgery used a grounded theory method to develop a substantive theory of the nurses' experiences. This current paper aimed to highlight the experiences of perioperative nurses when confronted with expressing a conscientious objection towards their participation in these procedures. A number of organizational and cultural barriers within the healthcare organization were seen to hamper their ability in expressing a conscience-based refusal, which lead to their reluctant participation. Perioperative nurses must feel safe to express a conscientious objection towards these types of surgical procedures and feel supported in doing so by their respective hospital organizations and not be forced to participate unwillingly. © 2016 John Wiley & Sons Ltd.

    While the results of early research suggested that perioperative antibiotic prophylaxis in tonsillectomy patients is associated with many benefits, these data were not confirmed by further studies and meta-analyses. The aim of this study was to investigate the usefulness and efficacy of antibiotic monotherapy in the healing of surgical wounds of patients undergoing bilateral resection of the palatine tonsils, based on an analysis of selected objective and subjective characteristics of wound healing during the postoperative period. The study included 50 men and women who underwent routine resection of the palatine tonsils. The patients were randomized into two groups: Group I, undergoing tonsillectomy with cefuroxime prophylaxis (n = 25), and Group II, who were not given perioperative antibiotic therapy (n = 25). The severity of signs and complaints recorded on postoperative days 1-10 was scored on 3- and 10-item scales. The only significant intergroup differences pertained to problems with swallowing food and fluids on postoperative days 4-6, 8 and 9 (less prevalent in Group II), postoperative use of analgesics on postoperative day 9 (less frequent in Group II), the degree of mucosal swelling in the operated area on postoperative days 3 and 7 (less severe in Group II), and the amount of fibrin covering the tonsillar niches on the third postoperative day (significantly higher in Group I). The administration of antibiotics for prevention or control of infection should be preceded by a comprehensive analysis of the potential benefits and risks. Perioperative use of antibiotics is justified only in selected cases, i.e. in individuals with comorbidities.

  1. Update on perioperative management of the child with asthma

    Directory of Open Access Journals (Sweden)

    2012-04-01

    Full Text Available Asthma represents the leading cause of morbidity from a chronic disease among children. Dealing with this disease during the perioperative period of pediatric surgical procedures is, therefore, quite common for the anesthesiologist and other professionalities involved. Preoperative assessment has a key role in detecting children at increased risk of perioperative respiratory complications. For children without an optimal control of symptoms or with a recent respiratory tract infection elective surgery should be postponed, if possible, after the optimization of therapy. According to clinical setting, loco-regional anesthesia represents the desirable option since it allows to avoid airway instrumentation. Airway management goals are preventing the increase of airflow resistance during general anesthesia along with avoiding triggers of bronchospasm. When their use is possible, face mask ventilation and laringeal mask are considered more reliable than tracheal intubation for children with asthma. Sevoflurane is the most commonly used anesthetic for induction and manteinance. Salbutamol seems to be useful in preventing airflow resistance rise after endotracheal intubation. Mechanical ventilation should be tailored according to pathophysiology of asthma: an adequate expiratory time should be setted in order to avoid a positive end-expiratory pressure due to expiratory airflow obstruction. Pain should be prevented and promptly controlled with a loco-regional anesthesia technique when it is possible. Potential allergic reactions to drugs or latex should always be considered during the whole perioperative period. Creating a serene atmosphere should be adopted as an important component of interventions in order to guarantee the best care to the asthmatic child.

    Public reporting of patient and graft outcomes in a national registry and close Centers for Medicare and Medicaid Services oversight has resulted in transplantation being a highly regulated surgical discipline. Despite this, transplantation surgery lacks comprehensive tracking and reporting of perioperative quality measures. Therefore, the aim of this study was to determine the association between a kidney transplantation centers' perioperative quality benchmarking and graft and patient outcomes. This was an analysis of 2011 aggregate data compiled from 2 national datasets that track outcomes from member hospitals and transplantation centers. The transplantation centers included in this study were composed of accredited US kidney transplantation centers that report data through the national registry and are associate members of the University HealthSystem Consortium. A total of 16,811 kidney transplantations were performed at 236 centers in the United States in 2011, of which 10,241 (61%) from 93 centers were included in the analysis. Of the 6 perioperative quality indicators, 3 benchmarked metrics were significantly associated with a kidney transplantation center's underperformance: mean ICU length of stay (C-statistic 0.731; p = 0.002), 30-day readmissions (C-statistic 0.697; p = 0.012) and in-hospital complications (C-statistic 0.785; p = 0.001). The composite quality index strongly correlated with inadequate center performance (C-statistic 0.854; p < 0.001, R(2) = 0.349). The centers in the lowest quartile of the quality index performed 2,400 kidney transplantations in 2011, which led to 2,640 more hospital days, 4,560 more ICU days, 120 more postoperative complications, and 144 more patients with 30-day readmissions, when compared with centers in the 3 higher-quality quartiles. An objective index of a transplantation center's quality of perioperative care is significantly associated with patient and graft survival. Copyright © 2014 American College of

    The optimal management of patients with resectable gastric cancer continues to evolve in Western countries. Following publication of the US Intergroup 0116 and UK Medical Research Council MAGIC trials, there are now two standards of care for adjuvant therapy in resectable gastric cancer, at least in the Western world: postoperative chemoradiotherapy and perioperative epirubicin/cisplatin/fluorouracil (ECF) chemotherapy. We hypothesize that adding chemoradiation to standard perioperative ECF chemotherapy will achieve further survival gains. We also believe there are advantages to administering chemoradiation in the preoperative rather than postoperative setting. In this article, we describe the TOPGEAR trial, which is a randomised phase III trial comparing control arm therapy of perioperative ECF chemotherapy with experimental arm therapy of preoperative chemoradiation plus perioperative ECF chemotherapy. Eligible patients with resectable adenocarcinoma of the stomach or gastroesophageal junction will be randomized to receive either perioperative chemotherapy alone (3 preoperative and 3 postoperative cycles of ECF) or perioperative chemotherapy plus preoperative chemoradiation. In the chemoradiation arm, patients receive 2 cycles of ECF plus chemoradiation prior to surgery, and then following surgery 3 further cycles of ECF are given. The trial is being conducted in two Parts; Part 1 (phase II component) has recruited 120 patients with the aim of assessing feasibility, safety and preliminary efficacy of preoperative chemoradiation. Part 2 (phase III component) will recruit a further 632 patients to provide a total sample size of 752 patients. The primary endpoint of the phase III trial is overall survival. The trial includes quality of life and biological substudies, as well as a health economic evaluation. In addition, the trial incorporates a rigorous quality assurance program that includes real time central review of radiotherapy plans and central review of

    Neurologic injury after regional anesthesia or pain medicine procedures is rare. Postprocedural neurologic deficits may create high levels of anxiety for the patient and practitioner, although most deficits are limited in severity and can be expected to fully resolve with time. Postoperative anesthesia-related neuraxial and peripheral nerve injuries are reviewed to define an efficient, structured approach to these complications. Emphasis is placed on acutely stratifying the urgency and scope of diagnostic testing or consultation necessity, initiating appropriate definitive treatments, and defining appropriate out-of-hospital follow-up and symptom management. Studies pertinent to the recognition, evaluation, and treatment of neurologic assessment of perioperative nerve injury and published since the last advisory on the topic are reviewed and a new structured algorithmic approach is proposed. The evolving literature on postoperative inflammatory neuropathies is reviewed to help define the clinical criteria and to identify patients who would benefit from early neurological evaluation. New sections review potential acute interventions to improve neurologic outcome and long-term management of neuropathic pain resulting from perioperative nerve injury.

    Neuropathy of the posterior femoral cutaneous nerve may manifest as pain and paresthesia in the skin over the inferior buttocks, posterior thigh, and popliteal region. Current treatment options include physical and oral pain therapy, perineural injections, and surgical neurectomy. Perineural steroid injections may provide short-term pain relief; however, to our knowledge, there is currently no minimally invasive denervation procedure for sustained pain relief that could serve as an alternative to surgical neurectomy. Percutaneous cryoablation of nerves is a minimally invasive technique that induces a sustained nerve conduction block through temporary freezing of the neural layers. It can result in long-lasting pain relief, but has not been described for the treatment of neuropathy-mediated PFCN pain. We report a technique of MR-guided cryoablation of the posterior femoral cutaneous nerve resulting in successful treatment of PFCN-mediated sitting pain. Cryoablation of the posterior femoral cutaneous nerve seems a promising, minimally invasive treatment option that deserves further investigation. (orig.)

    - An increasing number of patients wear nail polish, artificial nails or have piercings.- There is uncertainty about the perioperative management of these items, especially when located outside the surgical area.- In the majority of hospitals, patients are urged to remove these items preoperatively, under the assumption that they might cause problems.- Frequently, however, these items cannot be removed straightforwardly.- Nail polish and artificial nails only very rarely cause perioperative problems and therefore do not need to be removed pre-operatively.- The same applies to most piercings, except when located in or near the respiratory tract, if they have sharp endings or if they might cause problems as a result of the perioperative positioning of the patient.- Providing adequate information to the patient, knowledge about removal of these items and documentation of agreed arrangements are all important.- A national guideline concerning perioperative policy is urgently required.

    Full Text Available OBJECTIVE: The standard therapy for patients with high-level spinal cord injury is long-term mechanical ventilation through a tracheostomy. However, in some cases, this approach results in death or disability. The aim of this study is to highlight the anesthetics and perioperative aspects of patients undergoing insertion of a diaphragmatic pacemaker. METHODS: Five patients with quadriplegia following high cervical traumatic spinal cord injury and ventilator-dependent chronic respiratory failure were implanted with a laparoscopic diaphragmatic pacemaker after preoperative assessments of their phrenic nerve function and diaphragm contractility through transcutaneous nerve stimulation. ClinicalTrials.gov: NCT01385384. RESULTS: The diaphragmatic pacemaker placement was successful in all of the patients. Two patients presented with capnothorax during the perioperative period, which resolved without consequences. After six months, three patients achieved continuous use of the diaphragm pacing system, and one patient could be removed from mechanical ventilation for more than 4 hours per day. CONCLUSIONS: The implantation of a diaphragmatic phrenic system is a new and safe technique with potential to improve the quality of life of patients who are dependent on mechanical ventilation because of spinal cord injuries. Appropriate indication and adequate perioperative care are fundamental to achieving better results.

    Lunar calendars, publishing recommendations for daily life, are gaining more and more attention in Germany, where 10.5% of the population believe in lunar effects on disease. A widespread and often heard belief is that a full moon has the most negative effects on surgical outcome. The present study evaluates the effects of lunar phase on perioperative complications in total hip arthroplasty. We performed a retrospective study with 305 patients being provided with a primary hip arthroplasty. To identify possible influences of the lunar phase on perioperative complications we investigated data such as operation length, blood loss and course of C-reactive protein that were collected during the patients' stay in the hospital and allocated them to moon illumination. There were no significant differences in all collected data concerning the lunar phase (p > 0.05). Although not statistically significant, there were fewer operations during the full moon phase. Therefore there is no evidence that lunar phase has an effect on perioperative complications in total hip arthroplasty. Fewer, though not significantly fewer, operations were performed during the full moon phase. Although this was not a prospective randomized trial, the statistical magnitude of the results does not support any recommendations for scheduling patients for total hip arthroplasty at any particular day of the lunar phase.

    Patients with skeletal dysplasia frequently require surgery. This patient population has an increased risk for peri-operative complications related to the anatomy of their upper airway, abnormalities of tracheal-bronchial morphology and function; deformity of their chest wall; abnormal mobility of their upper cervical spine; and associated issues with general health and body habitus. Utilizing evidence analysis and expert opinion, this study aims to describe best practices regarding the peri-operative management of patients with skeletal dysplasia. A panel of 13 multidisciplinary international experts participated in a Delphi process that included a thorough literature review; a list of 22 possible care recommendations; two rounds of anonymous voting; and a face to face meeting. Those recommendations with more than 80% agreement were considered as consensual. Consensus was reached to support 19 recommendations for best pre-operative management of patients with skeletal dysplasia. These recommendations include pre-operative pulmonary, polysomnography; cardiac, and neurological evaluations; imaging of the cervical spine; and anesthetic management of patients with a difficult airway for intubation and extubation. The goals of this consensus based best practice guideline are to provide a minimum of standardized care, reduce perioperative complications, and improve clinical outcomes for patients with skeletal dysplasia. © 2017 Wiley Periodicals, Inc.

The pooled HR and 95% CI for overall survival (OS and disease-free survival (DFS were used to assess the prognostic value. The association of PNI with pathological characteristics was evaluated by OR and 95% CI. Results. A total of 13 cohorts were retrieved, covering 2770 patients treated by surgery. The cumulative analysis revealed a statistical correlation between PNI and poor OS (HR = 1.76, 95% CI: 1.54–2.20, and P<0.00001, as well as poor DFS (HR = 1.96, 95% CI: 1.42–2.71, and P<0.001. Moreover, analysis of 1475 patients showed improved PNI in T3 + T4 (OR = 0.39, 95% CI: 0.21–0.70, and P=0.002, N+ (OR = 0.52, 95% CI: 0.40–0.69, and P<0.00001, and G3 + G4 (OR = 0.66, 95% CI: 0.48–0.90, and P=0.008 patients compared with T1 + T2, N−, and G1 + G2 ones, respectively. No significant heterogeneity was found between the studies. Conclusions. PNI is an adverse prognostic biomarker in esophageal and EGJ carcinoma. Moreover, PNI implies advanced T, N stage and poor cell differentiation.

    Complementary integrative health therapies have a perioperative role in the reduction of pain, analgesic use, and anxiety, and increasing patient satisfaction. However, long implementation lags have been quantified. The Consolidated Framework for Implementation Research (CFIR) can help mitigate this translational problem. We reviewed evidence for several nonpharmacological treatments (CFIR domain: characteristics of interventions) and studied external context and organizational readiness for change by surveying providers at 11 Veterans Affairs (VA) hospitals (domains: outer and inner settings). We asked patients about their willingness to receive music and studied the association between this and known risk factors for opioid use (domain: characteristics of individuals). We implemented a protocol for the perioperative use of digital music players loaded with veteran-preferred playlists and evaluated its penetration in a subgroup of patients undergoing joint replacements over a 6-month period (domain: process of implementation). We then extracted data on postoperative recovery time and other outcomes, comparing them with historic and contemporary cohorts. Evidence varied from strong and direct for perioperative music and acupuncture, to modest or weak and indirect for mindfulness, yoga, and tai chi, respectively. Readiness for change surveys completed by 97 perioperative providers showed overall positive scores (mean >0 on a scale from -2 to +2, equivalent to >2.5 on the 5-point Likert scale). Readiness was higher at Durham (+0.47) versus most other VA hospitals (range +0.05 to +0.63). Of 3307 veterans asked about willingness to receive music, approximately 68% (n = 2252) answered "yes." In multivariable analyses, a positive response (acceptability) was independently predicted by younger age and higher mean preoperative pain scores (>4 out of 10 over 90 days before admission), factors associated with opioid overuse. Penetration was modest in the targeted subset (39

    In some retrospective studies perioperative transfusions during oncologic surgery have been shown to decrease the time interval between surgery and local and/or distant recurrence of cancer. This study examines the disease-related effect, if any, of perioperative blood transfusions among 108 patients with localized carcinoma of the prostate treated by radioactive iodine-125 seed implantation of the prostate and lymphadenectomy. When all subjects were analyzed, there was no statistical difference of local and distant failure between the transfused and nontransfused groups. Patients with well-differentiated tumors had statistically fewer local recurrences (0% vs 22%, p = 0.036) if they were transfused perioperatively. However, the difference in distant metastases (0% vs 11%) was not statistically significant (p = 0.21). In contrast, patients with moderately and poorly differentiated disease receiving transfusions had more local recurrences and metastases, though this was not statistically significant. Our data suggest that there is no obvious evidence that perioperative blood transfusions have an adverse effect on local recurrence or distant metastases for iodine-125 seed implantation of carcinoma of the prostate

    full-text articles for eligibility, assessed the risk of bias for each included study, and abstracted data. Main results Five studies met the inclusion criteria for this review, including 101,005 adults and 132 endophthalmitis cases. While the sample size was very large, the heterogeneity of the study designs and modes of antibiotic delivery made it impossible to conduct a formal meta-analysis. Interventions investigated included the utility of adding vancomycin and gentamycin to the irrigating solution compared with standard balanced saline solution irrigation alone, use of intracameral cefuroxime with or without topical levofloxacin perioperatively, periocular penicillin injections and topical chloramphenicol-sulfadimidine drops compared with topical antibiotics alone, and mode of antibiotic delivery (subconjunctival versus retrobulbar injections; fixed versus separate instillation of gatifloxacin and prednisolone). The risk of bias among studies was low to unclear due to information not being reported. We identified one ongoing study. Two studies compared any antibiotic with no antibiotic. One study, which compared irrigation with antibiotics in balanced salt solution (BSS) versus BSS alone, was not sufficiently powered to detect differences in endophthalmitis between groups (very low-certainty evidence). One study found reduced risk of endophthalmitis when combining intracameral cefuroxime and topical levofloxacin (risk ratio (RR) 0.14, 95% confidence interval (CI) 0.03 to 0.63; 8106 participants; high-certainty evidence) or using intracameral cefuroxime alone (RR 0.21, CI 0.06 to 0.74; 8110 participants; high-certainty evidence) compared with placebo, and an uncertain effect when using topical levofloxacin alone compared with placebo (RR 0.72, CI 0.32 to 1.61; 8103 participants; moderate-certainty evidence).

    Full Text Available Background and objectives: Currently, endoscopic medicine is being increasingly used, albeit not without risks. Therefore, this study evaluated the factors associated with perioperative complications in endoscopic surgery with intraoperative irrigation. Method: A cohort study of six months duration. Patients aged ≥ 18 years undergoing endoscopic surgery with the use of irrigation fluids during the intraoperative period were included. Exclusion criteria were: use of diuretics, kidney failure, cognitive impairment, hyponatremia prior to surgery, pregnancy, and critically ill. The patients who presented with or without complications during the perioperative period were allocated into two groups. Complications evaluated were related to neurological, cardiovascular and renal changes, and perioperative bleeding. Results: In total, 181 patients were enrolled and 39 excluded; therefore, 142 patients met the study criteria. Patients with complications amounted to 21.8%, with higher prevalence in endoscopic prostate surgery, followed by hysteroscopy, bladder, knee, and shoulder arthroscopy (58.1%, 36.9%, 19.4%, 3.8%, 3.2% respectively. When comparing both groups, we found association with complications in univariate analysis: age, sex, smoking, heart disease, ASA, serum sodium at the end of surgery, total irrigation fluid administered, TURP, and hysteroscopy. However, in multiple regression analysis for complications, only age (OR = 1.048, serum sodium (OR = 0.962, and volume of irrigation fluid administered during surgery (OR = 1.001 were independent variables.

    To present tactics for optimizing outpatient vaginal hysterectomy and describe perioperative outcomes in a large consecutive case series. This is a descriptive study and review of clinical outcomes in 1,071 patients selected to undergo vaginal hysterectomy for benign indications from 2000 to 2010. The setting is a single-surgeon private practice in a community hospital. Outcome measures include length of hospital stay, estimated blood loss, operative time, uterine weight, and perioperative complications, including hospital readmissions and emergency room visits. One thousand seventy-one of 1,162 cases (92%, 95% confidence interval [CI] 90.5-93.7) were total vaginal hysterectomies, of which 1,029 (96%, 95% CI 94.9-97.3) were discharged the same day after surgery. The median operative time was 34 minutes (range 17-210 minutes), and estimated blood loss was 45 mL (range 5-800 mL). The median patient age was 46 years (range 27-86 years), and median uterine weight was 160 g (range 25-1,380 g). One hundred ninety-three patients (18%, 95% CI 15.8-20.5) were nulliparous and 218 (20%, 95% CI 18-22.9) had prior pelvic surgery. Five patients (0.5%, 95% CI 0.2-1.1) required readmission or emergency room evaluation within the first 30 days. Vaginal hysterectomy can be successfully adopted as a same-day discharge procedure. In this population, regardless of previous pelvic surgery or nulliparity, good perioperative outcomes have been achieved.

    We aimed to evaluate the effectiveness of intervention by a perioperative multidisciplinary support team for radical esophagectomy for esophageal cancer. We retrospectively reviewed 85 consecutive patients with esophageal cancer who underwent radical esophagectomy via right thoracotomy or thoracoscopic surgery with gastric tube reconstruction. Twenty-one patients were enrolled in the non-intervention group (group N) from May 2011 to September 2012, 31 patients in the perioperative rehabilitation group (group R) from October 2012 to April 2014, and 33 patients in the multidisciplinary support team group (group S) from May 2014 to September 2015. Morbidity rates were 38, 45.2, and 42.4% for groups N, R, and S, respectively. Although there were no significant differences in the incidence of pneumonia among the groups, the durations of fever and C-reactive protein positivity were shorter in group S. Moreover, postoperative oral intake commenced earlier [5.9 (5-8) days] and postoperative hospital stay was shorter [19.6 (13-29) days] for group S. The intervention by a perioperative multidisciplinary support team for radical esophagectomy was effective in preventing the progression and prolongation of pneumonia as well as earlier ambulation, oral feeding, and shortening of postoperative hospitalization.

    We aimed to investigate the effect of perioperative analgesia with nonselective cyclooxygenase-2 inhibitor dexketoprofen and opioid drug omnopon on the functional activity of immune cells in tumor excision murine model. Lewis lung carcinoma cells were transplanted into hind paw of C57/black mice. On the 23th day tumor was removed. Analgesic drugs were injected 30 min before and once a day for 3 days after the surgery. Biological material was obtained a day before, 1 day and 3 days after the tumor removal. IFN-γ, IL-4, IL-10 and TGF-β mRNA levels in splenic cells were assessed by quantitative real-time RT-PCR. Cytotoxic activity of splenocytes was estimated by flow cytometry. We found that in splenocytes of mice received opioid analgesia IL-10 mRNA level was increased 2.3 times on day one after the surgery compared to preoperative level (P dexketoprofen group this parameter did not change. IFN-γ gene expression level on day 3 after tumor removal was 40% higher in splenocytes of dexketoprofen treated mice as compared with omnopon treated animals (P dexketoprofen against (50.2 ± 3.3)% in omnopon group. In conclusion, perioperative analgesia with cyclooxygenase inhibitor dexketoprofen in contrast to opioid analgesia with omnopon preserves higher functional activity of murine immune cells in the experimental model of tumor surgery.

    The anesthetic management of adolescents undergoing bariatric surgery presents a number of challenges, including increased risk of postoperative opioid-related respiratory depression. These patients could benefit from adjunctive analgesics with opioid-sparring effects to optimize perioperative pain control. Dexmedetomidine, a selective α2-adrenoreceptor agonist, has sedative and analgesic properties with no respiratory depressant effects. To determine the effect of intraoperative dexmedetomidine on opioid requirement and perioperative pain management in obese adolescents undergoing bariatric surgery. An observational study of 26 consecutive patients treated with and without dexmedetomidine during the intraoperative period was conducted. The dexmedetomidine treated patients received a loading dose over 30min and a continuous infusion thereafter. The standard group represented patients who received an institutional standard anesthetic without dexmedetomidine. The primary outcome was total perioperative intravenous morphine equivalent (MEq). We also examined reported pain scores during the perioperative period. While there were no significant differences in age, height and weight category, there were imbalances on race distribution between the two groups. Both groups received similar doses of ketorolac and acetaminophen perioperatively. Overall, during 48h postoperatively, the dexmedetomidine group received significantly less total MEq administration compared with the standard group. Three patients in the dexmedetomidine group required ephedrine to treat an episode of hypotension. These results suggest that the use of dexmedetomidine during bariatric surgery in the morbidly obese adolescent population is associated with decreased opioid utilization during the perioperative period. Future randomized studies will determine the role of dexmedetomidine in the pain management of obese adolescents undergoing bariatric surgery. Therapeutic, Level III. Copyright © 2017

    During the inflammation which occurs following nerve damage, macrophages are recruited to the site of injury. Phenotypic diversity is a hallmark of the macrophage lineage and includes pro-inflammatory M1 and anti-inflammatory M2 populations. Our aim in this study was to investigate the ability of polarized M0, M1, and M2 macrophages to secrete opioid peptides and to examine their relative contribution to the modulation of neuropathic pain. Mouse bone marrow-derived cells were cultured as unstimulated M0 macrophages or were stimulated into an M1 phenotype using lipopolysaccharide and interferon-γ or into an M2 phenotype using interleukin-4. The macrophage phenotypes were verified using flow cytometry for surface marker analysis and cytokine bead array for cytokine profile assessment. Opioid peptide levels were measured by radioimmunoassay and enzyme immunoassay. As a model of neuropathic pain, a chronic constriction injury (CCI) of the sciatic nerve was employed. Polarized M0, M1, and M2 macrophages (5 × 10 5 cells) were injected perineurally twice, on days 14 and 15 following CCI or sham surgery. Mechanical and heat sensitivity were measured using the von Frey and Hargreaves tests, respectively. To track the injected macrophages, we also transferred fluorescently stained polarized cells and analyzed the surface marker profile of endogenous and injected cells in the nerves ex vivo. Compared to M0 and M1 cells, M2 macrophages contained and released higher amounts of opioid peptides, including Met-enkephalin, dynorphin A (1-17), and β-endorphin. M2 cells transferred perineurally at the nerve injury site reduced mechanical, but not heat hypersensitivity following the second injection. The analgesic effect was reversed by the perineurally applied opioid receptor antagonist naloxone methiodide. M2 cells did not affect sensitivity following sham surgery. Neither M0 nor M1 cells altered mechanical and heat sensitivity in CCI or sham-operated animals. Tracing the

    A structured approach to perioperative patient management based on an enhanced recovery pathway protocol facilitates early recovery and reduces morbidity in high income countries. However, in low- and middle-income countries (LMICs), the feasibility of implementing enhanced recovery pathways and its influence on patient outcomes is scarcely investigated. To inform similar practice in LMICs for total hip and knee arthroplasty, it is necessary to identify potential factors for inclusion in such a programme, appropriate for LMICs. Applying a Delphi method, 33 stakeholders (13 arthroplasty surgeons, 12 anaesthetists and 8 physiotherapists) from 10 state hospitals representing 4 South African provinces identified and prioritised i) risk factors associated with poor outcomes, ii) perioperative interventions to improve outcomes and iii) patient and clinical outcomes necessary to benchmark practice for patients scheduled for primary elective unilateral total hip and knee arthroplasty. Thirty of the thirty-three stakeholders completed the 3 months Delphi study. The first round yielded i) 36 suggestions to preoperative risk factors, ii) 14 (preoperative), 18 (intraoperative) and 23 (postoperative) suggestions to best practices for perioperative interventions to improve outcomes and iii) 25 suggestions to important postsurgical outcomes. These items were prioritised by the group in the consecutive rounds and consensus was reached for the top ten priorities for each category. The consensus derived risk factors, perioperative interventions and important outcomes will inform the development of a structured, perioperative multidisciplinary enhanced patient care protocol for total hip and knee arthroplasty. It is anticipated that this study will provide the construct necessary for developing pragmatic enhanced care pathways aimed at improving patient outcomes after arthroplasty in LMICs.

    With increasing appreciation of the possible adverse effects of peri-operative blood transfusion, restrictive policies regarding use of blood products have been adopted in many surgical specialties. Although microvascular breast reconstruction has become a routine procedure, high peri-operative transfusion rates continue to be reported in the literature. In this study we examine the impact of our restrictive approach on blood transfusion rates and postoperative complications in patients undergoing microvascular blood transfusion. A retrospective review of patients undergoing microvascular breast reconstruction with abdominal flaps at a single institution was performed. Patient age and body mass index as well as type, timing and laterality of reconstruction was recorded. Pre-operative and post-operative hemoglobin and hematocrit were recorded. Peri-operative blood transfusion rates were calculated. Post-operative complication rates were compared between patients with higher and lower post-operative hemoglobin levels. Five hundred and twelve patients were included in this study. The peri-operative transfusion rate was 0.98% in this series. There was no significant difference between transfusion rates in unilateral and bilateral reconstructions (0.68 vs 1.36% p = 0.08) or immediate and delayed reconstructions (1.02 vs 0.51% p = 0.72 and 1.01 vs 1.60% p = 0.09 for unilateral and bilateral respectively). Lower post-operative hemoglobin levels were not associated with increased flap related, surgical or medical complications rates. A restrictive approach to peri-operative blood transfusion can be safely adopted in microvascular breast reconstruction without compromising flap viability or overall complication rates.

    Multimodal analgesia is standard practice for total knee arthroplasty; however, the role of regional techniques in improved perioperative outcomes remains unknown. The authors hypothesized that peripheral nerve blockade would result in lower pain scores and opioid consumption than two competing periarticular injection solutions. This three-arm, nonblinded trial randomized 165 adults undergoing unilateral primary total knee arthroplasty to receive (1) femoral catheter plus sciatic nerve blocks, (2) ropivacaine-based periarticular injection, or (3) liposomal bupivacaine-based periarticular injection. Primary outcome was maximal pain during postoperative day 1 (0 to 10, numerical pain rating scale) in intention-to-treat analysis. Additional outcomes included pain scores and opioid consumption for postoperative days 0 to 2 and 3 months. One hundred fifty-seven study patients received peripheral nerve block (n = 50), ropivacaine (n = 55), or liposomal bupivacaine (n = 52) and reported median maximal pain scores on postoperative day 1 of 3, 4, and 4.5 and on postoperative day 0 of 1, 4, and 5, respectively (average pain scores for postoperative day 0: 0.6, 1.7, and 2.4 and postoperative day 1: 2.5, 3.5, and 3.7). Postoperative day 1 median maximal pain scores were significantly lower for peripheral nerve blockade compared to liposomal bupivacaine-based periarticular injection (P = 0.016; Hodges-Lehmann median difference [95% CI] = -1 [-2 to 0]). After postanesthesia care unit discharge, postoperative day 0 median maximal and average pain scores were significantly lower for peripheral nerve block compared to both periarticular injections (ropivacaine: maximal -2 [-3 to -1]; P bupivacaine: maximal -3 [-4 to -2]; P bupivacaine over ropivacaine in periarticular injections for total knee arthroplasty.

  15. Hemostatic function to regulate perioperative bleeding in patients undergoing spinal surgery: A prospective observational study.

    Directory of Open Access Journals (Sweden)

    Atsushi Kimura

    Full Text Available Although bleeding is a common complication of surgery, routine laboratory tests have been demonstrated to have a low ability to predict perioperative bleeding. Better understanding of hemostatic function during surgery would lead to identification of high-risk patients for bleeding. Here, we aimed to elucidate hemostatic mechanisms to determine perioperative bleeding. We prospectively enrolled 104 patients undergoing cervical spinal surgery without bleeding diathesis. Blood sampling was performed just before the operation. Volumes of perioperative blood loss were compared with the results of detailed laboratory tests assessing primary hemostasis, secondary hemostasis, and fibrinolysis. Platelet aggregations induced by several agonists correlated with each other, and only two latent factors determined inter-individual difference. Platelet aggregability independently determined perioperative bleeding. We also identified low levels of plasminogen-activator inhibitor-1 (PAI-1 and α2-plasmin inhibitor to be independent risk factors for intraoperative and postoperative bleeding, respectively. Most important independent factor to determine postoperative bleeding was body weight. Of note, obese patients with low levels of PAI-1 became high-risk patients for bleeding during surgery. Our data suggest that bleeding after surgical procedure may be influenced by inter-individual differences of hemostatic function including platelet function and fibrinolysis, even in the patients without bleeding diathesis.

    This retrospective study aimed to assess the frequency and distribution of incidents encountered during the perioperative period of maxillary distraction with internal devices. The perioperative period was defined as the period between device placement and removal. Records of 20 patients treated during 2004-2011 with internal maxillary distraction osteogenesis were examined. Incidents were registered in terms of severity and need of intervention. Eighty percent of the patients experienced minor incidents, of which the most frequent were pain during activation and infections; 80% of these experienced ≥1 hard and soft tissue-related incidents, and 20% ≥1 device-related incidents. All incidents were solved with minimal or no intervention. Maxillary distraction using internal devices is a safe treatment with only minor incidents in the perioperative period. Preoperative planning and good cooperation are essential for preventing postoperative incidents. Prophylactic antibiotic treatment during the distraction period may be indicated.

    The 2010 Institute of Medicine (IOM) report, The Future of Nursing: Leading Change, Advancing Health, continues to be the most-viewed report in IOM history. Nearly three years after its publication, there are action coalitions of nursing and non-nursing agencies in 50 states and the District of Columbia collaborating to move the eight recommendations for action forward. There is much work to do to reshape health care delivery in the United States, and the IOM has identified nurses as key leaders in driving the reform. Every nurse must be educated on the key messages of the IOM report and become involved in moving these recommendations forward as well as in educating others on what needs to be done. AORN and perioperative nurses have a key role in voicing the unique needs of perioperative patients and in ensuring that perioperative patient care is represented in reform activities.

    There is increasing interest in evaluating the use of nonpharmacologic interventions such as music to minimize potential adverse effects of anxiety-reducing medications. This study used a quasi-experimental design to evaluate the effects of a perioperative music intervention (provided continuously throughout the preoperative, intraoperative, and postoperative periods) on changes in mean arterial pressure (MAP), heart rate, anxiety, and pain in women with a diagnosis of breast cancer undergoing mastectomy. A total of 30 women were assigned randomly to a control group or to the music intervention group. Findings indicated that women in the intervention group had a greater decrease in MAP and anxiety with less pain from the preoperative period to the time of discharge from the recovery room compared with women in the control group. Music is a noninvasive and low-cost intervention that can be easily implemented in the perioperative setting, and these findings suggest that perioperative music can reduce MAP, anxiety, and pain among women undergoing mastectomy for breast cancer.

    Full Text Available Background: Perioperative outcomes following surgery for brain tumors are an important indicator of the safety as well as efficacy of surgical intervention. Perioperative morbidity not only has implications on direct patient care, but also serves as an indicator of the quality of care provided, and enables objective documentation, for comparision in various clinical trials. We document our experience at a tertiary care referral, a dedicated neuro-oncology center in India. Materials and Methods: One hundred and ninety-six patients undergoing various surgeries for intra-axial brain tumors were analyzed. Routine microsurgical techniques and uniform antibiotic policy were used. Navigation/ intraoperative electrophysiological monitoring was not available. The endpoints assessed included immediate postoperative neurological status, neurological outcome at discharge, regional complications, systemic complications, overall morbidity, and mortality. Various risk factors assessed included clinico-epidemiological factors, tumor-related factors, and surgery-related factors. Univariate and multivariate analysis were performed. Results: Median age was 38 years. 72% had tumors larger than 4 cm. Neurological morbidity, and regional and systemic complications occurred in 16.8, 17.3, and 10.7%, respectively. Overall, major morbidity occurred in 18% and perioperative mortality rate was 3.6%. Although a few of the known risk factors were found to be significant on univariate analysis, none achieved significance on multivariate analysis. Conclusions: Our patients were younger and had larger tumors than are generally reported. Despite the unavailability of advanced intraoperative aids we could achieve acceptable levels of morbidity and mortality. Objective recording of perioperative events is crucial to document outcomes after surgery for brain tumors.

    Perioperative care in hip fracture patients with dementia can be complex. There is currently little scientific evidence on how care should be undertaken. The aim of the study was to describe the experience of anaesthesia nurses of the difficulties that emerge in care situations and how communication with patients can be maintained in the perioperative setting of hip fracture surgery. Individual interviews were conducted with ten anaesthesia nurses (5 men and 5 women). The interviews were carried out at a university hospital in Gothenburg (Sweden), and the data were analysed using qualitative content analysis. Three main response categories were discerned: 'Communication', 'Dementia as a special issue' and 'Practical issues'. Dementia was viewed as one of the most difficult and shifting diseases an individual may suffer from. Time must be allocated to communicate clearly and patiently, to meticulously plan and carry out care while providing distinct information to enable patient participation. Establishing a mental bridgehead by confirming the patients' perceptions/feelings significantly reduced distress in a majority of the patients. A holistic and respectful approach was deemed mandatory at all times. Patients are sometimes dependent on recognition, so that small personal items brought close to the patient during surgery can calm the patient. State-of-the-art analgesia and anxiolytic medications are mandatory. Perioperative problems can be overcome with patience, empathy and profound knowledge of how patients with dementia respond prior to surgery. Our results may serve as a source for future care and provide information about hospital settings for better perioperative care in patients with dementia. © 2015 Nordic College of Caring Science.

  1. Perioperative Anesthesiological Management of Patients with Pulmonary Hypertension

    Full Text Available Pulmonary hypertension is a major reason for elevated perioperative morbidity and mortality, even in noncardiac surgical procedures. Patients should be thoroughly prepared for the intervention and allowed plenty of time for consideration. All specialty units involved in treatment should play a role in these preparations. After selecting each of the suitable individual anesthetic and surgical procedures, intraoperative management should focus on avoiding all circumstances that could contribute to exacerbating pulmonary hypertension (hypoxemia, hypercapnia, acidosis, hypothermia, hypervolemia, and insufficient anesthesia and analgesia. Due to possible induction of hypotonic blood circulation, intravenous vasodilators (milrinone, dobutamine, prostacyclin, Na-nitroprusside, and nitroglycerine should be administered with the greatest care. A method of treating elevations in pulmonary pressure with selective pulmonary vasodilation by inhalation should be available intraoperatively (iloprost, nitrogen monoxide, prostacyclin, and milrinone in addition to invasive hemodynamic monitoring. During the postoperative phase, patients must be monitored continuously and receive sufficient analgesic therapy over an adequate period of time. All in all, perioperative management of patients with pulmonary hypertension presents an interdisciplinary challenge that requires the adequate involvement of anesthetists, surgeons, pulmonologists, and cardiologists alike.

    The presence of gastrointestinal (GI) cancer and its treatment might aggravate patient nutritional status. Malnutrition is one of the major factors affecting the postoperative course. We evaluated changes in perioperative nutritional status and risk factors of postoperative severe malnutrition in the GI cancer patients. Nutritional status was prospectively evaluated using patient-generated subjective global assessment (PG-SGA) perioperatively between May and September 2011. A total of 435 patients were enrolled. Among them, 279 patients had been diagnosed with gastric cancer and 156 with colorectal cancer. Minimal invasive surgery was performed in 225 patients. PG-SGA score increased from 4.5 preoperatively to 10.6 postoperatively (pgastric cancer patients, postoperative severe malnourishment increased significantly (p60, pgastric cancer (pgastric cancer, and open surgery remained significant as risk factors of severe malnutrition. The prevalence of severe malnutrition among GI cancer patients in this study increased from 2.3% preoperatively to 26.3% after an operation. Old age, preoperative weight loss, gastric cancer, and open surgery were shown to be risk factors of postoperative severe malnutrition. In patients at high risk of postoperative severe malnutrition, adequate nutritional support should be considered.

    This study aims to evaluate the effect of sleep apnea (SA) on perioperative complications after total joint arthroplasty (TJA) and whether the type of anesthesia influences these complications. Using the ninth and tenth revisions of the International Classification of Diseases, coding systems, we queried our institutional TJA database from January 2005 to June 2016 to identify patients with SA who underwent TJA. These patients were matched in a 1:3 ratio based on age, gender, type of surgery, and comorbidities to patients who underwent TJA but were not coded for SA. Perioperative complications were identified using the same coding systems. Multivariate analysis was used to test if SA is an independent predictor of perioperative complications and if type of anesthesia can affect these complications. A total of 1246 patients with SA were matched to 3738 patients without SA. Pulmonary complications occurred more frequently in patients with SA (1.7% vs 0.6%; P system complications and mortality (odds ratio = 15.88; 95% confidence interval, 3.93-64.07; P gastrointestinal complications, acute anemia, and mortality were lower in SA patients when regional anesthesia was used (P < .05). SA increases risk of postoperative pulmonary complications. The use of regional anesthesia may reduce risk of pulmonary complications and mortality in SA patients undergoing TJA.

  4. Prospective study of use of perioperative antimicrobial therapy in general surgery.

    LENUS (Irish Health Repository)

    Fennessy, Brendan G

    2012-02-03

    BACKGROUND: Perioperative antimicrobial therapy has demonstrated efficacy in reducing the rate of surgical site infections in clinical trials. With the emergence of antibiotic resistance, the risk of reaction, and the inevitable financial repercussions, use of prophylactic antibiotics is not a panacea, and their misuse may have considerable implications. The aim of this study was to assess the use of antibiotics in the perioperative period in both general and vascular surgery procedures. METHODS: A prospective study was undertaken of 131 patients with a mean age of 43 years (range one month-88 years), of whom 68 (51%) were male, who underwent twenty-seven different general or vascular surgery procedures over a four-week period. Each patient was evaluated from the time of antibiotic commencement through their operative procedure until the treatment was discontinued. RESULTS: A total of 73 patients (54%) received ten antibiotics, with 71 (97%) of these uses being prophylactic. Of the 15 appendectomies performed for uncomplicated appendicitis, the mean number of prophylactic antibiotic doses was 5.3 (range 1-12). Where they were documented, written postoperative directives were not adhered to in 18\\/27 prescriptions (66%). CONCLUSION: This study has demonstrated a lack of adherence to guidelines in the perioperative administration of antimicrobial agents. In addition, it calls attention to the economic implications of unnecessary prophylaxis.

    Feelings of trepidation or uncertainty regarding cardiovascular implantable electronic devices (CIEDs) in the perioperative period can often be mitigated by a thorough knowledge of societal recommendations, recommended management options, and familiarity with CIEDs. Given that effective interpretation of an interrogation report is vital to determining perioperative management options and applying societal recommendations, the creation and interpretation of St. Jude CIED interrogation reports are discussed. In an effort to increase the familiarity with St. Jude transvenous CIEDs amongst anesthesiologists, basic programming of a St. Jude pacemaker and implantable cardioverter defibrillator (ICD) also are described.

    2017-04-01

    Full Text Available Sleep is an important component of pediatric health and is crucial for cognitive development. Actigraphy is a validated, objective tool to capture sleep and movement data that is increasingly being used in the perioperative context. The aim of this review is to present recent pediatric studies that utilized actigraphy in the perioperative period, highlight gaps in the literature, and provide recommendations for future research. A literature search was completed using OVID and PubMed databases and articles were selected for inclusion based on relevance to the topic. The literature search resulted in 13 papers that utilized actigraphic measures. Results of the review demonstrated that actigraphy has been used to identify predictors and risk factors for poor postoperative sleep, examine associations among perioperative pain and sleep patterns, and assess activity and energy expenditure in both inpatient and outpatient settings. We propose expansion of actigraphy research to include assessment of sleep via actigraphy to: predict functional recovery in pediatric populations, to study postoperative sleep in high-risk pediatric patients, to test the efficacy of perioperative interventions, and to assess outcomes in special populations for which self-report data on sleep and activity is difficult to obtain.

    Full Text Available Purpose: The aim of the study was to present an original technique of catheter implantation for perioperative HDR-Ir192 brachytherapy in patients after palliative operations of unresectable locally advanced pancreatic tumors and to estimate the influence of perioperative HDR-Ir192 brachytherapy on pain relief in terminal pancreatic cancer patients. Material and methods: Eight patients with pancreatic tumors located in the head of pancreas underwent palliative operations with the use of HDR-Ir192 brachytherapy. All patients qualified for surgery reported pain of high intensity and had received narcotic painkillers prior to operation. During the last phase of the surgery, the Nucletron® catheters were implanted in patients to prepare them for later perioperative brachytherapy. Since the 6th day after surgery HDR brachytherapy was performed. Before each brachytherapy fraction the location of implants were checked using fluoroscopy. A fractional dose was 5 Gy and a total dose was 20 Gy in the area of radiation. A comparative study of two groups of patients (with and without brachytherapy with stage III pancreatic cancer according to the TNM scale was taken in consideration. Results and Conclusions: The authors claim that the modification of catheter implantation using specially designed cannula, facilitates the process of inserting the catheter into the tumor, shortens the time needed for the procedure, and reduces the risk of complications. Mean survival time was 5.7 months. In the group of performed brachytherapy, the mean survival time was 6.7 months, while in the group of no brachytherapy performed – 4.4 months. In the group of brachytherapy, only one patient increased the dose of painkillers in the last month of his life. Remaining patients took constant doses of medicines. Perioperative HDR-Ir192 brachytherapy could be considered as a practical application of adjuvant therapy for pain relief in patients with an advanced pancreatic cancer.

    2015-01-01

    Minimal mandatory monitoring in the perioperative period recommended by Association of Anesthetists of Great Britain and Ireland and American Society of Anesthesiologists are universally acknowledged and has become an integral part of the anesthesia practice. The technologies in perioperative monitoring have advanced, and the availability and clinical applications have multiplied exponentially. Newer monitoring techniques include depth of anesthesia monitoring, goal-directed fluid therapy, transesophageal echocardiography, advanced neurological monitoring, improved alarm system and technological advancement in objective pain assessment. Various factors that need to be considered with the use of improved monitoring techniques are their validation data, patient outcome, safety profile, cost-effectiveness, awareness of the possible adverse events, knowledge of technical principle and ability of the convenient routine handling. In this review, we will discuss the new monitoring techniques in anesthesia, their advantages, deficiencies, limitations, their comparison to the conventional methods and their effect on patient outcome, if any.

    The Joint Commission Surgical Care Improvement Project (SCIP) includes performance measures aimed at reducing surgical site infections (SSI). One measure defines approved perioperative antibiotics for general operative procedures. However, there may be a subset of procedures not adequately covered with the use of approved antibiotics. We hypothesized that piperacillin-tazobactam is a more appropriate perioperative antibiotic for pancreaticoduodenectomy (PD). In collaboration with hospital epidemiology and the Division of Infectious Diseases, we retrospectively reviewed records of 34 patients undergoing PD between March and May 2008 who received SCIP-approved perioperative antibiotics and calculated the SSI rate. After changing our perioperative antibiotic to piperacillin-tazobactam, we prospectively reviewed PDs performed between June 2008 and March 2009 and compared the SSI rates before and after the change. For 34 patients from March through May 2008, the SSI rate for PD was 32.4 per 100 cases. Common organisms from wound cultures were Enterobacter and Enterococcus (50.0% and 41.7%, respectively), and these were cefoxitin resistant. From June 2008 through March 2009, 106 PDs were performed. During this period, the SSI rate was 6.6 per 100 surgeries, 80% lower than during March through May 2008 (relative risk, 0.204; 95% confidence interval [CI], 0.086-0.485; P = .0004). Use of piperacillin-tazobactam as a perioperative antibiotic in PD may reduce SSI compared with the use of SCIP-approved antibiotics. Continued evaluation of SCIP performance measures in relationship to patient outcomes is integral to sustained quality improvement. Copyright © 2013 Mosby, Inc. All rights reserved.

    This study intends to evaluate whether regional common habits or differences in case-volume between surgeons are significative variables in the perioperative management of patients undergoing surgery for lumbar disc herniation. An e-mail survey was sent to all neurosurgeons working in Lombardy, Italy's most populated region. The survey consisted of 17 questions about the perioperative management of lumbar disc herniation. Forty-seven percent (47%) out of 206 Lombard neurosurgeons answered the survey. Although in some respects there is clear evidence in current literature on which is the best practice to adopt for an optimal management strategy, we noticed substantial differences between respondents, not only between hospitals but also between surgeons from the same hospital. Still, no differences were evident in a high vs low case-volume comparison. We identified no regional clusterization as for practical principles in the perioperative management of lumbar disc herniation and neither was case-volume a significative variable. Other causes may be relevant in the variability between the perioperative management and the outcomes achieved by different specialists.

    2017-07-01

    Many methods used to improve hospital and perioperative services productivity and quality of care have assumed that the hospital is essentially a factory, and therefore, that industrial engineering and manufacturing-derived redesign approaches such as Six Sigma and Lean can be applied to hospitals and perioperative services just as they have been applied in factories. However, a hospital is not merely a factory but also a complex adaptive system (CAS). The hospital CAS has many subsystems, with perioperative care being an important one for which concepts of factory redesign are frequently advocated. In this article, we argue that applying only factory approaches such as lean methodologies or process standardization to complex systems such as perioperative care could account for difficulties and/or failures in improving performance in care delivery. Within perioperative services, only noncomplex/low-variance surgical episodes are amenable to manufacturing-based redesign. On the other hand, complex surgery/high-variance cases and preoperative segmentation (the process of distinguishing between normal and complex cases) can be viewed as CAS-like. These systems tend to self-organize, often resist or react unpredictably to attempts at control, and therefore require application of CAS principles to modify system behavior. We describe 2 examples of perioperative redesign to illustrate the concepts outlined above. These examples present complementary and contrasting cases from 2 leading delivery systems. The Mayo Clinic example illustrates the application of manufacturing-based redesign principles to a factory-like (high-volume, low-risk, and mature practice) clinical program, while the Kaiser Permanente example illustrates the application of both manufacturing-based and self-organization-based approaches to programs and processes that are not factory-like but CAS-like. In this article, we describe how factory-like processes and CAS can coexist within a hospital and how

    Full Text Available Abstract Background Given the complexity of surgical care, perioperative patients are at high risk of opioid-related adverse drug events. Existing methods of detection, such as trigger tools and manual chart review, are time-intensive which makes sustainability challenging. Using strategic rule design, computerized surveillance may be an efficient, pharmacist-driven model for event detection that leverages existing staff resources. Methods Computerized adverse drug event surveillance uses a logic-based rules engine to identify potential adverse drug events or evolving unsafe clinical conditions. We extended an inpatient rule (administration of naloxone to detect opioid-related oversedation and respiratory depression to perioperative care at a large academic medical center. Our primary endpoint was the adverse drug event rate. For all patients with a naloxone alert, manual chart review was performed by a perioperative clinical pharmacist to assess patient harm. In patients with confirmed oversedation, other patient safety event databases were queried to determine if they could detect duplicate, prior, or subsequent opioid-related events. Results We identified 419 cases of perioperative naloxone administration. Of these, 101 were given postoperatively and 69 were confirmed as adverse drug events after chart review yielding a rate of 1.89 adverse drug events/1000 surgical encounters across both the inpatient and ambulatory settings. Our ability to detect inpatient opioid adverse drug events increased 22.7% by expanding surveillance into perioperative care. Analysis of historical surveillance data as well as a voluntary reporting database revealed that 11 of our perioperative patients had prior or subsequent harmful oversedation. Nine of these cases received intraoperative naloxone, and 2 had received naloxone in the post-anesthesia care unit. Pharmacist effort was approximately 3 hours per week to evaluate naloxone alerts and confirm adverse drug

    Full Text Available Accurate assessments of intravascular fluid status are an essential part of perioperative care and necessary in the management of the hemodynamically unstable patient. Goal-directed fluid management can facilitate resuscitation of the hypovolemic patient, reduce the risk of fluid overload, reduce the risk of the injudicious use of vasopressors and inotropes, and improve clinical outcomes. In this paper, we discuss the strengths and limitations of a spectrum of noninvasive and invasive techniques for assessing and monitoring intravascular volume status and fluid responsiveness in the perioperative and critically ill patient.

    Full Text Available Melatonin, a new addition to the armamentarium of anesthesiologist, has some unique properties that are highly desirable in routine peri-operative care. Available clinical data show that preoperative melatonin is as effective as benzodiazepines in reducing preoperative anxiety with minimal action on psychomotor performance and sleep wake cycle. It may be considered as a safe and effective alternative of benzodiazepines as preoperative anxiolytic. It may have opioid sparing effect, may reduce intraocular pressure, and have role in prevention of postoperative delirium. The short-term administration of melatonin is free from significant adverse effects also.

    Retrospective review. To investigate the effect of age on the perioperative and radiographic complications associated with multilevel (>or=5) fusion of the cervicothoracic spine. Although the elderly comprise a substantial proportion of patients presenting with complex spinal pathology necessitating multilevel procedures across the cervical and cervicothoracic spine, the risk of perioperative and radiographic complications after these procedures is unknown. Between 2000 and 2007, 58 patients 65 years of age or older at a single institution underwent instrumented cervicothoracic spinal fusion of at least 5 levels. Fifty-eight patients under the age of 65 from the same time period served as a control group. A retrospective review of all hospital records, operative reports, radiographs, and clinic notes was conducted. Complications were classified as intraoperative, major and minor postoperative, and need for revision surgery. Flexion-extension radiographs were examined at discharge, 1.5, 6, 12 months, and then yearly, thereafter to evaluate fusion status and instrumentation-related complications. Principal diagnoses included spondylostenosis, malignancy, vertebral fracture, and osteomyelitis. Both groups were similar in number of levels fused (elderly, 6.7 +/- 2.1; control, 6.3 +/- 1.7) and circumferential procedures (27 vs. 28), respectively. There were no significant differences in operative time, blood loss, or length of hospital stay. Rates of intraoperative (5.2% vs. 3.4%), major (20.7% vs. 17.2%) and minor postoperative complications (27.6% vs. 22.4%), and reoperation (8.6% vs. 8.6%) were similar between the 2 groups. Utilization of a combined anterior-posterior fusion was associated with increased perioperative complications in the elderly on univariate but not multivariate analyses. Radiographic evidence of fusion was also comparable between the 2 groups. Perioperative complication rates of multilevel (>or=5) cervicothoracic spinal fusion in the elderly are

    The purpose of the current study was to comprehensively evaluate occupational radiation exposure to all intraoperative and perioperative personnel involved in radioguided surgical procedures utilizing 18 F-fluorodeoxyglucose ( 18 F-FDG). Radiation exposure to surgeon, anesthetist, scrub technologist, circulating nurse, preoperative nurse, and postoperative nurse, using aluminum oxide dosimeters read by optically stimulated luminescence technology, was evaluated during ten actual radioguided surgical procedures involving administration of 18 F-FDG. Mean patient dosage of 18 F-FDG was 699 ± 181 MBq (range 451-984). Mean time from 18 F-FDG injection to initial exposure of personnel to the patient was shortest for the preoperative nurse (75 ± 63 min, range 0-182) followed by the circulating nurse, anesthetist, scrub technologist, surgeon, and postoperative nurse. Mean total time of exposure of the personnel to the patient was longest for the anesthetist (250 ± 128 min, range 69-492) followed by the circulating nurse, scrub technologist, surgeon, postoperative nurse, and preoperative nurse. Largest deep dose equivalent per case was received by the surgeon (164 ± 135 μSv, range 10-580) followed by the anesthetist, scrub technologist, postoperative nurse, circulating nurse, and preoperative nurse. Largest deep dose equivalent per hour of exposure was received by the preoperative nurse (83 ± 134 μSv/h, range 0-400) followed by the surgeon, anesthetist, postoperative nurse, scrub technologist, and circulating nurse. On a per case basis, occupational radiation exposure to intraoperative and perioperative personnel involved in 18 F-FDG radioguided surgical procedures is relatively small. Development of guidelines for monitoring occupational radiation exposure in 18 F-FDG cases will provide reassurance and afford a safe work environment for such personnel. (orig.)

    For over a year Professor Marc Verny's geriatric department at Pitié-Salpêtrière hospital in Paris has had ten beds set aside for the perioperative care of elderly people. This geriatric perioperative unit (UPOG) offers patients the skills of a multidisciplinary team trained in the specificities of caring for elderly patients often suffering from polypathology. The team works closely together around a common goal: the rapid return of the patient's autonomy during the postoperative period, crucial for the future of elderly people. So far UPOG's results have been very positive, as more than 90% of patients regain their autonomy after a short and uncomplicated period of postoperative care.

    Colorectal surgery is commonly performed for colorectal cancer and other pathology such as diverticular and inflammatory bowel disease. Despite significant advances, such as laparoscopic techniques and multidisciplinary recovery programs, morbidity and mortality remain high and vary among surgical centers. The use of scoring systems and assessment of functional capacity may help in identifying high-risk patients and predicting complications. An understanding of perioperative factors affecting colon blood flow and oxygenation, suppression of stress response, optimal fluid therapy, and multimodal pain management are essential. These fundamental principles are more important than any specific choice of anesthetic agents. Anesthesiologists can significantly contribute to enhance recovery and improve the quality of perioperative care.

    The aim of this review is to summarize data published on the use of perioperative hypnosis in patients undergoing breast cancer surgery (BCS). Indeed, the majority of BCS patients experience stress, anxiety, nausea, vomiting, and pain. Correct management of the perioperative period and surgical removal of the primary tumor are clearly essential but can affect patients on different levels and hence have a negative impact on oncological outcomes. This review examines the effect of clinical hypnosis performed during the perioperative period. Thanks to its specific properties and techniques allowing it to be used as complementary treatment preoperatively, hypnosis has an impact most notably on distress and postoperative pain. During surgery, hypnosis may be applied to limit immunosuppression, while, in the postoperative period, it can reduce pain, anxiety, and fatigue and improve wound healing. Moreover, hypnosis is inexpensive, an important consideration given current financial concerns in healthcare. Of course, large randomized prospective studies are now needed to confirm the observed advantages of hypnosis in the field of oncology. PMID:27635132

    The self-expandable metallic stent (SEMS) is an excellent non-invasive tool for emergent bowel obstruction. This study was designed to evaluate the clinical usefulness of the SEMS for avoiding perioperative complications. We analyzed a total of 47 consecutive patients who had a bowel obstruction due to colorectal cancer at initial diagnosis between 2012 and 2017 from hospital records. Perioperative complications occurred in 30% (14/47) of patients. Univariate and multivariate logistic regression analyses identified an age of more than 75 years [p=0.037, OR=6.84 (95% CI=1.11-41.6)] and the absence of an SEMS treatment [p=0.028, OR=18.5 (95% CI=1.36-250.0)] as independent risk factors for perioperative complications. Pneumonia (12.7% (6/47)) was the most common complication. There were no pneumonia patients (0% (0/15)) who were treated with the SEMS. In contrast to patients with the non-SEMS treatment, 18.7% (6/32) of all patients and 35.7% (5/14) of elderly patients had pneumonia. The SEMS is a safe and effective treatment for avoiding perioperative complications, particularly pneumonia, and may be a crucial strategy in elderly patients with acute obstruction due to colorectal cancer.

    The religious organization of Jehovah's Witnesses numbers more than 7 million members worldwide, including 165,000 members in Germany. Although Jehovah's Witnesses strictly refuse the transfusion of allogeneic red blood cells, platelets and plasma, Jehovah's Witness patients may nevertheless benefit from modern therapeutic concepts including major surgical procedures without facing an excessive risk of death. The present review describes the perioperative management of surgical Jehovah's Witness patients aiming to prevent fatal anemia and coagulopathy. The cornerstones of this concept are 1) education of the patient about blood conservation techniques generally accepted by Jehovah's Witnesses, 2) preoperative optimization of the cardiopulmonary status and correction of preoperative anemia and coagulopathy, 3) perioperative collection of autologous blood, 4) minimization of perioperative blood loss and 5) utilization of the organism's natural anemia tolerance and its acute accentuation in the case of life-threatening anemia.

  6. Risk reduction: perioperative smoking intervention

    Smoking is a well-known risk factor for perioperative complications. Smokers experience an increased incidence of respiratory complications during anaesthesia and an increased risk of postoperative cardiopulmonary complications, infections and impaired wound healing. Smokers have a greater risk...... of postoperative intensive care admission. Even passive smoking is associated with increased risk at operation. Preoperative smoking intervention 6-8 weeks before surgery can reduce the complications risk significantly. Four weeks of abstinence from smoking seems to improve wound healing. An intensive, individual...... approach to smoking intervention results in a significantly better postoperative outcome. Future research should focus upon the effect of a shorter period of preoperative smoking cessation. All smokers admitted for surgery should be informed of the increased risk, recommended preoperative smoking cessation...

    Full Text Available We aimed to investigate the effect of perioperative analgesia with nonselective cyclooxygenase-2 inhibitor dexketoprofen and opioid drug omnopon on the functional activity of immune cells in tumor excision murine model. Lewis lung carcinoma cells were transplanted into hind paw of C57/black mice. On the 23th day tumor was removed. Analgesic drugs were injected 30 min before and once a day for 3 days after the surgery. Biological material was obtained a day before, 1 day and 3 days after the tumor removal. IFN-γ, IL-4, IL-10 and TGF-β mRNA levels in splenic cells were assessed by quantitative real-time RT-PCR. Cytotoxic activity of splenocytes was estimated by flow cytometry. We found that in splenocytes of mice received opioid analgesia IL-10 mRNA level was increased 2.3 times on day one after the surgery compared to preoperative level (P < 0.05, while in dexketoprofen group this parameter did not change. IFN-γ gene expression level on day 3 after tumor removal was 40% higher in splenocytes of dexketoprofen treated mice as compared with omnopon treated animals (P < 0.05. Cytotoxic activity of splenocytes on day 3 postsurgery was (62.2 ± 2.4% in dexketoprofen against (50.2 ± 3.3% in omnopon group. In conclusion, perioperative analgesia with cyclooxygenase inhibitor dexketoprofen in contrast to opioid analgesia with omnopon preserves higher functional activity of murine immune cells in the experimental model of tumor surgery.

    To determine which strategies are currently used for (anti)coagulation management and blood conservation during cardiac surgery in Canada. Institutional survey. University hospital. All sites performing cardiac surgery in Canada. None. The response rate was 85%. Anticoagulation with heparin is monitored routinely through the activated coagulation time (ACT). Less than 10% of centers use heparin concentrations (Hepcon HMS, Medtronic), thromboelastography, or other point-of-care tests perioperatively. Eighty percent of centers routinely use tranexamic acid as the primary antifibrinolytic agent; however aprotinin until recently, was used more commonly for patients at increased risk for bleeding. Retrograde autologous prime is commonly used (62%); however, cell savers are uncommon for routine patients undergoing cardiac surgery (29%). Although most hospitals use a hematocrit of 20% to 21% for transfusing red blood cells, more than 50% of intensive care units do not have written guidelines for the administration of protamine, fresh frozen plasma, platelets, or factor VIIa. At least one third of centers do not audit their transfusion practices regularly. The majority of Canadian institutions do not use point-of-care tests other than ACT. Most institutions do not have algorithms for management of bleeding following cardiac surgery and at least 30% do not monitor their transfusion practice perioperatively. Cardiac surgery patients in Canada may benefit from a standardized approach to blood conservation in the perioperative period.

    ESSENTIALS: Targeting of factor VIII values is a challenge during perioperative replacement therapy in hemophilia. This study aims to identify the extent and predictors of factor VIII underdosing and overdosing. Blood group O predicts underdosing and is associated with perioperative bleeding. To increase quality of care and cost-effectiveness of treatment, refining of dosing is obligatory. Perioperative administration of factor VIII (FVIII) concentrate in hemophilia A may result in both underdosing and overdosing, leading to respectively a risk of bleeding complications and unnecessary costs. This retrospective observational study aims to identify the extent and predictors of underdosing and overdosing in perioperative hemophilia A patients (FVIII levels < 0.05 IU mL(-1)). One hundred nineteen patients undergoing 198 elective, minor, or major surgical procedures were included (median age 40 years, median body weight 75 kg). Perioperative management was evaluated by quantification of perioperative infusion of FVIII concentrate and achieved FVIII levels. Predictors of underdosing and (excessive) overdosing were analyzed by logistic regression analysis. Excessive overdosing was defined as upper target level plus ≥ 0.20 IU mL(-1). Depending on postoperative day, 7-45% of achieved FVIII levels were under and 33-75% were above predefined target ranges as stated by national guidelines. A potential reduction of FVIII consumption of 44% would have been attained if FVIII levels had been maintained within target ranges. Blood group O and major surgery were predictive of underdosing (odds ratio [OR] 6.3, 95% confidence interval [CI] 2.7-14.9; OR 3.3, 95% CI 1.4-7.9). Blood group O patients had more bleeding complications in comparison to patients with blood group non-O (OR 2.02, 95% CI 1.00-4.09). Patients with blood group non-O were at higher risk of overdosing (OR 1.5, 95% CI 1.1-1.9). Additionally, patients treated with bolus infusions were at higher risk of excessive

    Full Text Available Protein S (PS along with activated protein C plays an important role in the down-regulation of in vivo thrombin generation. Its deficiency can cause abnormal and inappropriate clot formation within the circulation necessitating chronic anticoagulation therapy. The risk of developing thrombotic complications is heightened in the perioperative period in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB. Heparin resistance is very rare in these patients, especially when antithrombin levels are near normal. Management of CPB in this scenario is quite challenging. We report the perioperative management, particularly the CPB management, of a patient with type I PS deficiency and incidentally detected heparin resistance, who underwent coronary artery bypass grafting with CPB.

    Patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) need many blood products due to deficiency of coagulation factors. Blood transfusion therapy in patients with excessive bleeding after CPB is generally empiric. We checked and studied the fibrinogen concentration and transfusion, as well as bleeding amount in the perioperative period. The study was approved by our institutional ethics committee. Thirty patients were studied. Blood samples were obtained at the induction of anesthesia (before CPB), at the end of CPB, at the end of operation, and on the next morning, or before the patient was given fresh frozen plasma in the intensive care unit. For all cases, fibrinogen concentration and platelet concentration were lowest at the end of CPB. Fibrinogen concentration rose up to before CPB level on the next morning. The group in which fibrinogen concentration was less than 150 mg x dl(-1) at the end of CPB consumed more blood products than the group with fibrinogen concentration of over 150 mg x dl(-1). Blood transfusion therapy based on fibrinogen concentration is needed to maintain adequacy of the perioperative blood transfusion and blood conservation in cardiac surgery.

    In recent years, operating theatre nurse students' education focused on ethics, basic values and protecting and promoting the patients' dignity in perioperative practice. Health professionals are frequently confronted with ethical issues that can impact on patient's care during surgery. The objective of this study was to present what operating theatre nursing students perceived and interpreted as undignified caring in perioperative practice. The study has a descriptive design with a hermeneutic approach. Data were collected using Flanagan's critical incident technique. Operating theatre nurse students from Sweden and Norway participated and collected data in 2011, after education in ethics and dignity. Data consisting of 47 written stories and the text were analysed with hermeneutical text interpretation. The study was approved by the Karlstad University's Research Ethics Committee. The findings show careless behaviour and humiliating actions among health professionals. Health professionals commit careless acts by rendering the patient invisible, ignoring the patient's worry and pain and treating the patient as an object. They also humiliate the patient when speaking in negative terms about the patient's body, and certain health professionals blame the patients for the situation they are in. Health professionals lack the willingness and courage to protect the patient's dignity in perioperative practice. In the discussion, we have illuminated how professional ethics may be threatened by more pragmatic and utilitarian arguments contained in regulations and transplant act. The findings reveal that patients were exposed to unnecessary suffering; furthermore, the operating theatre nurse students suffered an inner ethical conflict due to the undignified caring situations they had witnessed. © The Author(s) 2014.

    2014-02-01

    Full Text Available Background: Patients with liver cirrhosis have high surgical risks due to malnutrition, impaired immunity, coagulopathy, and encephalopathy. However, there is no information in English literature about the results of liver cirrhotic patients who underwent instrumented lumbar surgery. The purpose of this study is to report the perioperative complications, clinical outcomes and determine the surgical risk factors in cirrhotic patients. Methods: We retrospectively reviewed 29 patients with liver cirrhosis who underwent instrumented lumbar surgery between 1997 and 2009. The hepatic functional reserves of the patients were recorded according to the Child-Turcotte-Pugh scoring system. Besides, fourteen other variables and perioperative complications were also collected. To determine the risks, we divided the patients into two groups according to whether or not perioperative complications developed. Results: Of the 29 patients, 22 (76% belonged to Child class A and 7 (24% belonged to Child class B. Twelve patients developed one or more complications. Patients with Child class B carried a significantly higher incidence of complications than those with Child class A (p = 0.011. In the Child class A group, patients with 6 points had a significantly higher incidence of complications than those with 5 points (p = 0.025. A low level of albumin was significantly associated with higher risk, and a similar trend was also noted for the presence of ascites although statistical difference was not reached. Conclusion: The study concludes that patients with liver cirrhosis who have undergone instrumented lumbar surgery carry a high risk of developing perioperative complications, especially in those with a Child-Turcotte-Pugh score of 6 or more.

    Interhospital competition has been shown to influence the adoption of surgical techniques and approaches, clinical patient outcomes, and health care resource use for select surgical procedures. However, little is known regarding these dynamics as they relate to spine surgery. This investigation sought to examine the relationship between interhospital competitive intensity and perioperative outcomes following lumbar spinal fusion. This study used the Nationwide Inpatient Sample dataset, years 2003, 2006, and 2009. Patients were included based on the presence of the International Classification of Disease, Ninth Edition, Clinical Modification (ICD-9-CM) codes corresponding to lumbar spinal fusion, as well as on the presence of data on the Herfindahl-Hirschman Index (HHI). The outcome measures are perioperative complications, defined using an ICD-9-CM coding algorithm. The HHI, a validated measure of competition within a market, was used to assess hospital market competitiveness. The HHI was calculated based on the hospital cachement area. Multiple regression was performed to adjust for confounding variables including patient age, gender, primary payer, severity of illness score, primary versus revision fusion, anterior versus posterior approach, national region, hospital bed size, location or teaching status, ownership, and year. Perioperative clinical outcomes were assessed based on ICD-9-CM codes with modifications. In total, 417,520 weighted patients (87,999 unweighted records) were analyzed. The mean cachement area HHI was 0.31 (range 0.099-0.724). The average patient age was 55.4 years (standard error=0.194), and the majority of patients were female (55.8%, n=232,727). The majority of procedures were primary spinal fusions (92.7%, n=386,998) and fusions with a posterior-only technique (81.5%, n=340,271). Most procedures occurred in the South (42.5%, n=177,509) or the Midwest (27.0%, n=112,758) regions. In the multiple regression analysis, increased hospital

Monaldi, Naples, Italy Abstract: The increasing number of opioid users among chronic pain patients, and opioid abusers among the general population, makes perioperative pain management challenging for health care professionals. Anesthesiologists, surgeons, and nurses should be familiar with some pharmacological phenomena which are typical of opioid users and abusers, such as tolerance, physical dependence, hyperalgesia, and addiction. Inadequate pain management is very common in these patients, due to common prejudices and fears. The target of preoperative evaluation is to identify comorbidities and risk factors and recognize signs and symptoms of opioid abuse and opioid withdrawal. Clinicians are encouraged to plan perioperative pain medications and to refer these patients to psychiatrists and addiction specialists for their evaluation. The aim of this review was to give practical suggestions for perioperative management of surgical opioid-tolerant patients, together with schemes of opioid conversion for chronic pain patients assuming oral or transdermal opioids, and

    We implemented a two-year project to develop a security-gated management system for the perioperative setting using radio-frequency identification (RFID) technology to enhance the management efficiency of the OR. We installed RFID readers beside the entrances to the OR and changing areas to receive and process signals from the RFID tags that we sewed into surgical scrub attire and shoes. The system also required integrating automatic access control panels, computerized lockers, light-emitting diode (LED) information screens, wireless networks, and an information system. By doing this, we are able to control the flow of personnel and materials more effectively, reduce OR costs, optimize the registration and attire-changing process for personnel, and improve management efficiency. We also anticipate this system will improve patient safety by reducing the risk of surgical site infection. Application of security-gated management systems is an important and effective way to help ensure a clean, convenient, and safe management process to manage costs in the perioperative area and promote patient safety.

    To analyze the clinical effect of minimal extracorporeal circulation (MECC) in blood conservation perioperatively coronary artery bypass graft (CABG). The data of 120 cases received simple CABG since August 2006 to October 2009 was analyzed retrospectively. All the patients were divided to three groups according to the mode of circulation support in-operation: MECC, conventional extracorporeal circulation (cECC) or off-pump, 40 cases in each group. Jostra MECC system with normal temperature was used in MECC group, and common membrane oxygenator with moderate hypo-temperature was used in cECC group. Collect the data of coagulation and the blood cytological examination perioperatively, the draining volume during the first 24 h after operation, and consumption of blood products perioperatively. Standard and logistic EuroSCORE were higher in MECC group than the others (P blood products in cECC group, but no difference among the three groups. MECC could reduce the ruin to blood cell and interfere to coagulation function during the conventional ECC procedure, decrease the postoperative draining volume and requirement of blood products.

    Local anesthetic efficacy of tramadol has been reported following intradermal application. Our aim was to investigate the effect of perineural tramadol as the sole analgesic in two pain models. Male Wistar rats (280-380 g; N = 5/group) were used in these experiments. A neurostimulation-guided sciatic nerve block was performed and 2% lidocaine or tramadol (1.25 and 5 mg) was perineurally injected in two different animal pain models. In the flinching behavior test, the number of flinches was evaluated and in the plantar incision model, mechanical and heat thresholds were measured. Motor effects of lidocaine and tramadol were quantified and a motor block score elaborated. Tramadol, 1.25 mg, completely blocked the first and reduced the second phase of the flinching behavior test. In the plantar incision model, tramadol (1.25 mg) increased both paw withdrawal latency in response to radiant heat (8.3 ± 1.1, 12.7 ± 1.8, 8.4 ± 0.8, and 11.1 ± 3.3 s) and mechanical threshold in response to von Frey filaments (459 ± 82.8, 447.5 ± 91.7, 320.1 ± 120, 126.43 ± 92.8 mN) at 5, 15, 30, and 60 min, respectively. Sham block or contralateral sciatic nerve block did not differ from perineural saline injection throughout the study in either model. The effect of tramadol was not antagonized by intraperitoneal naloxone. High dose tramadol (5 mg) blocked motor function as well as 2% lidocaine. In conclusion, tramadol blocks nociception and motor function in vivo similar to local anesthetics

Patients who underwent bariatric surgery were identified from the American College of Surgeons National Surgical Quality Improvement Program dataset (2012-2014). The 17 most common perioperative complications were analyzed by multivariate regression analysis to determine the effect of complications on the risk of VTE. The postoperative incidence of VTE was 0.5% (n = 59,424 bariatric surgeries). The average time to diagnosis of VTE was 11.6 days. 80% of VTE events occurred after discharge. A major complication occurred prior to VTE in 22.6% of patients. The more complications experienced by an individual patient, the more likely they were to experience VTE. Unadjusted thirty-day mortality increased 13.89-fold following VTE (p bariatric surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

    Endoscopic endonasal surgery relies heavily on specialized operative instrumentation and optimization of endocrinological and other critical adjunctive intraoperative factors. Several studies and worldwide initiatives have previously established that intraoperative and perioperative surgical checklists can minimize the incidence of and prevent adverse events. The aim of this article was to outline some of the most common considerations in the perioperative and intraoperative preparation for endoscopic endonasal transsphenoidal surgery. The authors implemented and prospectively evaluated a customized checklist at their institution in 25 endoscopic endonasal operations for a variety of sellar and skull base pathological entities. Although no major errors were detected, near misses pertaining primarily to missing components of surgical equipment or instruments were identified in 9 cases (36%). The considerations in the checklist provided in this article can serve as a basic template for further customization by centers performing endoscopic endonasal surgery, where their application may reduce the incidence of adverse or preventable errors associated with surgical treatment of sellar and skull base lesions.

    The development of new therapeutic strategies for treatment of metastasized colorectal carcinoma requires biologically relevant and adequate animal models that generate both reproducible metastasis and the dissemination of tumor cells in the form of so-called minimal residual disease (MRD), an expression of the systemic character of neoplastic disease. We injected immunoincompetent nude mice intraportally with different numbers (1 × 10 5 , 1 × 10 6 and 5 × 10 6 cells) of the human colon carcinoma cell lines HT-29 and SW-620 and investigated by histological studies and CK-20 RT-PCR the occurrence of hematogenous metastases and the dissemination of human tumor cells in bone marrow. Only the injection of 1 × 10 6 cells of each colon carcinoma cell line produced acceptable perioperative mortality with reproducible induction of hepatic metastases in up to 89% of all animals. The injection of 1 × 10 6 cells also generated tumor cell dissemination in the bone marrow in up to 63% of animals with hepatic metastases. The present intraportal injection model in immunoincompetent nude mice represents a biologically relevant and adequate animal model for the induction of both reproducible hepatic metastasis and tumor cell dissemination in the bone marrow as a sign of MRD

    To determine the survival rates of dogs and cats that underwent surgical treatment for traumatic diaphragmatic hernia within 24 hours of admission and determine whether timing of surgery affected perioperative survival rate. Retrospective study. 63 dogs and 29 cats treated surgically for traumatic diaphragmatic hernia. Medical records were reviewed to evaluate associations between perioperative survival rates and variables including timing of surgery in relation to admission and acute versus chronic diaphragmatic hernia. Among the 92 animals, 82 (89.1%) were discharged alive after surgery. Sixty-four (69.6%) patients received surgical intervention within 12 hours of admission, and 84 (91.3%) received surgical intervention within 24 hours of admission. Median time from admission to discharge was 4 days (2 to 33 days). Data for acute cases (68 dogs and cats) were analyzed separately. Sixty-three (92.6%) patients with acute diaphragmatic hernia received surgical intervention within 24 hours of admission to the hospital, and 59 (93.7%) of these patients were discharged alive. Twenty-nine (42.6%) patients with acute diaphragmatic hernia received surgical intervention within 24 hours of trauma, and 26 of 29 (89.7%) patients were discharged alive. An overall acute and chronic perioperative survival rate of 89.7% was observed in dogs and cats that received surgical intervention within 24 hours of admission. Results in 68 dogs and cats that underwent surgery within 24 hours of admission suggested that early surgical intervention for acute diaphragmatic hernia was associated with good perioperative survival rates.

    Throughout the history of medicine, physicians have relied upon disruptive innovations and technologies to improve the quality of care delivered, patient outcomes, and patient satisfaction. The implementation of mobile technology in health care is quickly becoming the next disruptive technology. We first review the history of mobile technology over the past 3 decades, discuss the impact of hardware and software, explore the rapid expansion of applications (apps), and evaluate the adoption of mobile technology in health care. Next, we discuss how technology serves as the vehicle that can transform traditional didactic learning into one that adapts to the learning behavior of the student by using concepts such as the flipped classroom, just-in-time learning, social media, and Web 2.0/3.0. The focus in this modern education paradigm is shifting from teacher-centric to learner-centric, including providers and patients, and is being delivered as context-sensitive, or semantic, learning. Finally, we present the methods by which connected health systems via mobile devices increase information collection and analysis from patients in both clinical care and research environments. This enhanced patient and provider connection has demonstrated benefits including reducing unnecessary hospital readmissions, improved perioperative health maintenance coordination, and improved care in remote and underserved areas. A significant portion of the future of health care, and specifically perioperative medicine, revolves around mobile technology, nimble learners, patient-specific information and decision-making, and continuous connectivity between patients and health care systems. As such, an understanding of developing or evaluating mobile technology likely will be important for anesthesiologists, particularly with an ever-expanding scope of practice in perioperative medicine.

    Adjuvant perineural dexmedetomidine can be used to prolong the analgesic effect of interscalene brachial plexus block (ISB). We investigated the optimal dose of dexmedetomidine in ISB for postoperative analgesia in patients undergoing arthroscopic shoulder surgery. One hundred patients scheduled for elective shoulder arthroscopic surgery were enrolled in this randomized, double-blind study. Ultrasound-guided ISB was performed before general anesthesia using 22 mL of ropivacaine 0.5% combined with 1, 1.5, or 2 μg/kg of dexmedetomidine (group D1, D2, and D3, respectively) or with normal saline as a control (group R, n = 25 per group). The primary outcome was the duration of analgesia (DOA), numeric pain rating scale (NRS), and consumption of additional analgesics during 36 h after ISB. Secondary outcome included durations of motor and sensory block (DOM and DOS), hemodynamic variables and sedation and dyspnea scores. Ninety-seven patients completed the study. The DOS, DOM, and DOA were significantly longer in the dexmedetomidine groups than in group R. The DOA was significantly longer in group D3 than in groups D1 (P = .026) and D2 (P = .039). The DOA was 808.13 ± 179.97, 1032.60 ± 288.14, 1042.04 ± 188.13, and 1223.96 ± 238.06 min in groups R, D1, D2, and D3, respectively. The NRS score was significantly higher in group R than in the dexmedetomidine groups 12 h after ISB (P surgery (P = .008 and P = .011, respectively). There were no significant differences in consumption of rescue analgesics, sedation, and dyspnea scores between the study groups. Perineural dexmedetomidine 2 μg/kg could be the optimal dose in ISB for arthroscopic shoulder surgery in that it provides an adequate DOA. However, this dose was associated with increased risk of hypotension.

    In surgical practice, great attention is given to the perioperative management of the elective surgical patient with regard to surgical planning, stratification of cardiopulmonary risk, and postoperative assessment for complication. However, growing evidence supports the beneficial role for implementation of a consistent and literature-based approach to perioperative nutrition therapy. Determining nutrition risk should be a routine component of the preoperative evaluation. As with the above issues, this concept begins with the clinician's first visit with the patient as risk is assessed and the severity of the surgical insult considered. If the patient is an appropriate candidate for benefit from preoperative support, a plan for initiation and reassessment should be implemented. Once appropriate nutrition end points have been achieved, special consideration should be given to beneficial practices the immediate day preceding surgery that may better prepare the patient for the intervention from a metabolic standpoint. In the operating room, consideration should be given to the potential placement of enteral access during the index operation as well as judicious and targeted intraoperative resuscitation. Immediately following the intervention, adequate resuscitation and glycemic control are key concepts, as is an evidence-based approach to the early advancement of an enteral/oral diet in the postoperative patient. Through the implementation of perioperative nutrition therapy plans in the elective surgery setting, outcomes can be improved.

    Pontes, João Paulo Jordão; Mendes, Florentino Fernandes; Vasconcelos, Mateus Meira; Batista, Nubia Rodrigues

    Diabetes mellitus (DM) is characterized by alteration in carbohydrate metabolism, leading to hyperglycemia and increased perioperative morbidity and mortality. It evolves with diverse and progressive physiological changes, and the anesthetic management requires attention regarding this disease interference in multiple organ systems and their respective complications. Patient's history, physical examination, and complementary exams are important in the preoperative management, particularly glycosylated hemoglobin (HbA1c), which has a strong predictive value for complications associated with diabetes. The goal of surgical planning is to reduce the fasting time and maintain the patient's routine. Patients with Type 1 DM must receive insulin (even during the preoperative fast) to meet the basal physiological demands and avoid ketoacidosis. Whereas patients with Type 2 DM treated with multiple injectable and/or oral drugs are susceptible to develop a hyperglycemic hyperosmolar state (HHS). Therefore, the management of hypoglycemic agents and different types of insulin is fundamental, as well as determining the surgical schedule and, consequently, the number of lost meals for dose adjustment and drug suspension. Current evidence suggests the safe target to maintain glycemic control in surgical patients, but does not conclude whether it should be obtained with either moderate or severe glycemic control.

    To explore the feasibility of subserosal injection of carbon nanoparticle via venous infusion needle to label lymph node and its application value in laparoscopic radical gastrectomy. Forty patients with gastric cancer were randomly divided into two groups (carbon nanoparticle group and control group). Subserosal injection of carbon nanoparticle around the tumor was performed via venous infusion needle laparoscopically at the beginning of surgery in carbon nanoparticles group, while the patients routinely underwent laparoscopic radical gastrectomy in control group. Results of harvested lymph nodes were compared between the two groups. The perioperative complications and the side effect of carbon nanoparticle were also evaluated. The average number of harvested lymph node in carbon nanoparticle group (31.7±7.6) was significantly higher than that in control group (19.8±6.1, Pinjection of carbon nanoparticle via venous infusion needle to label lymph nodes during laparoscopic radical gastrectomy is safe and feasible. It can increase the number of harvested lymph node, especially the small node.

    In 1993, the American Society of Anesthesiologists (ASA) published guidelines stating that automatic perioperative suspension of Do Not Resuscitate (DNR) orders conflicts with patients' rights to self-determination. Almost 20 years later, we aimed to explore both patient and doctor views concerning perioperative DNR status. Five-hundred consecutive patients visiting our preoperative evaluation clinic were surveyed and asked whether they had made decisions regarding resuscitation and to rate their agreement with several statements concerning perioperative resuscitation. Anesthesiologists, surgeons and internists at our tertiary referral institution were also surveyed. They were asked to assess their likelihood of following a hypothetical patient's DNR status and to rate their level of agreement with a series of non-scenario related statements concerning ethical and practical aspects of perioperative resuscitation. Over half of patients (57%) agreed that pre-existing DNR requests should be suspended while undergoing a surgical procedure under anesthesia, but 92% believed a discussion between the doctor and patient regarding perioperative resuscitation plans should still occur. Thirty percent of doctors completing the survey believed that DNR orders should automatically be suspended intraoperatively. Anesthesiologists (18%) were significantly less likely to suspend DNR orders than surgeons (38%) or internists (34%) (p < 0.01). Although many patients agree that their DNR orders should be suspended for their operation, they expect a discussion regarding the performance and nature of perioperative resuscitation. In contrast to previous studies, anesthesiologists were least likely to automatically suspend a DNR order.

    Idiopathic pulmonary fibrosis (IPF) is a progressive diffuse lung disease associated with an increased risk of lung cancer. Patients with IPF sometimes develop a life-threatening acute exacerbation of IPF (AE-IPF) after lung cancer surgery. In this retrospective study, pirfenidone, an antifibrotic agent, was perioperatively administered to IPF patients with lung cancer with the aim of preventing postoperative AE-IPF, and the feasibility and clinical outcomes were investigated. Twelve IPF patients with concomitant lung cancer who received perioperative pirfenidone treatment (PPT) for lung cancer surgery were retrospectively investigated. Sixteen IPF patients undergoing lung cancer surgery without PPT were analyzed as historical controls. Compared to the controls, the PPT patients had a more severely impaired preoperative pulmonary function and a larger number of limited pulmonary resections. There was a significant preoperative decrease in the serum KL-6 levels of the PPT patients. No severe pirfenidone-related complications or IPF-related events occurred in the PPT patients, while six control patients developed AE-IPF (P = 0.0167). A quantitative histopathological evaluation of resected lung specimens found that tissue changes associated with IPF were significantly fewer in the PPT patients (P = 0.021). PPT is a feasible perioperative treatment for IPF patients with lung cancer. Its effectiveness in preventing postoperative AE-IPF thus warrants prospective verification.

  1. Perioperative Parenteral Nutrition in Adults With Inflammatory Bowel Disease: A Review of the Literature.

    Science.gov (United States)

    Schwartz, Emily

    2016-04-01

    Inflammatory bowel disease (IBD) is a chronic inflammatory condition with numerous nutrition implications, including an increased risk of malnutrition and various nutrient deficiencies. Surgical interventions are often necessary in the treatment of IBD, and patients with IBD presenting for surgery often have multiple issues, including acute inflammatory processes, malnutrition, anemia, and infections, which may increase the likelihood of poor surgical outcomes. Thus, determining adjunctive treatments that may decrease postoperative complications is paramount. Although enteral nutrition (EN) is considered the preferred nutrition support modality when the gastrointestinal tract is accessible and functional, parenteral nutrition (PN) may provide a suitable alternative when the use of EN is not feasible. The aim of this review is to evaluate the currently available literature on the impact of perioperative PN on postoperative complications, disease severity, and nutrition status in adults with IBD. Six studies within the past 10 years investigated this topic and are analyzed here. Results indicate general trends toward improvements in postoperative outcomes, disease severity, and nutrition status associated with perioperative PN use. Although results appear promising, additional, larger studies with an emphasis on PN composition will improve our understanding of the benefits of perioperative PN in adults with IBD. © 2015 American Society for Parenteral and Enteral Nutrition.

    2012-02-01

    While isolated factor VII (FVII) deficiency is being more frequently diagnosed owing to improved preoperative screening procedures, there is no specific guideline for perioperative management of such patients. To complicate the issue, FVII activity levels seem to correlate less well with the risk of hemorrhage than the patient's past and family bleeding history do. We have devised expert consensus recommendations for managing such patients perioperatively, taking into consideration the personal and family bleeding history, the FVII activity level and the inherent bleeding risk of the procedure itself. We hope that clinicians will find this a useful tool in the decision-making process, thereby limiting the use of recombinant factor VIIa to those who need it most, and preventing possible thrombotic complications in those without a strong indication for its use.

    Morbidly obese patients are at increased risk for venous thromboembolism (VTE) after bariatric surgery. Perioperative chemoprophylaxis is used routinely with bariatric surgery to decrease the risk of VTE. When bleeding occurs, routine chemoprophylaxis is often withheld due to concerns about inciting another bleeding event. We sought to evaluate the relationship between perioperative bleeding and postoperative VTE in bariatric surgery. The American College of Surgeons-National Surgical Quality Improvement Program (NSQIP) dataset between 2012 and 2014 was queried to identify patients who underwent bariatric surgery. Gastric bypass (n = 28,145), sleeve gastrectomy (n = 30,080), bariatric revision (n = 324), and biliopancreatic diversion procedures (n = 492) were included. Univariate and multivariate regressions were used to determine perioperative factors predictive of postoperative VTE within 30 days in patients who experience a bleeding complication necessitating transfusion. The rate of bleeding necessitating transfusion was 1.3%. Bleeding was significantly more likely to occur in gastric bypass compared to sleeve gastrectomy (1.6 vs. 1.0%) (p surgeries, increased age, length of stay, operative time, and comorbidities including hypertension, dyspnea with moderate exertion, partially dependent functional status, bleeding disorder, transfusion prior to surgery, ASA class III/IV, and metabolic syndrome increased the perioperative bleeding risk (p Bariatric surgery patients who receive postoperative blood transfusion are at a significantly increased risk for VTE. The etiology of VTE in those who are transfused is likely multifactorial and possibly related to withholding chemoprophylaxis and the potential of a hypercoagulable state induced by the transfusion. In those who bleed, consideration should be given to reinitiating chemoprophylaxis when safe, extending treatment after discharge, and screening ultrasound.

  5. High-dose buprenorphine: perioperative precautions and management strategies.

    Science.gov (United States)

    Roberts, D M; Meyer-Witting, M

    2005-02-01

    Buprenorphine has been in clinical use in anaesthesia for several decades. Recently, the high-dose sublingual formulation (Subutex, Reckitt Benckiser, Slough, U.K.) has been increasingly used as maintenance therapy in opioid dependence, as an alternative to methadone and other pharmacological therapies. Buprenorphine has unique pharmacological properties making it well suited for use as a maintenance therapy in opioid dependence. However, these same properties may cause difficulty in the perioperative management of pain. Buprenorphine is a partial opioid agonist, attenuating the effects of supplemental illicit or therapeutic opioid agonists. As a result of its high receptor affinity, supplemental opioids do not readily displace buprenorphine from the opioid receptor in standard doses. High-dose buprenorphine has an extended duration of action that prolongs both of these effects. The perioperative management of patients stabilized on high-dose buprenorphine and undergoing surgery requires consideration of the likely analgesic requirements. Where possible the buprenorphine should be continued. Pain management should focus on maximizing non-opioid analgesia, local anaesthesia and non-pharmacological techniques. Where pain may not be adequately relieved by these methods, the addition of a full opioid agonist such as fentanyl or morphine at appropriate doses should be considered, accompanied by close monitoring in a high dependency unit. In situations where this regimen is unlikely to be effective, preoperative conversion to morphine or methadone may be an option. Where available, liaison with a hospital-based alcohol and drug service should always be considered.

  6. Chick embryo xenograft model reveals a novel perineural niche for human adipose-derived stromal cells

    2015-09-01

    Full Text Available Human adipose-derived stromal cells (hADSC are a heterogeneous cell population that contains adult multipotent stem cells. Although it is well established that hADSC have skeletal potential in vivo in adult organisms, in vitro assays suggest further differentiation capacity, such as into glia. Thus, we propose that grafting hADSC into the embryo can provide them with a much more instructive microenvironment, allowing the human cells to adopt diverse fates or niches. Here, hADSC spheroids were grafted into either the presumptive presomitic mesoderm or the first branchial arch (BA1 regions of chick embryos. Cells were identified without previous manipulations via human-specific Alu probes, which allows efficient long-term tracing of heterogeneous primary cultures. When grafted into the trunk, in contrast to previous studies, hADSC were not found in chondrogenic or osteogenic territories up to E8. Surprisingly, 82.5% of the hADSC were associated with HNK1+ tissues, such as peripheral nerves. Human skin fibroblasts showed a smaller tropism for nerves. In line with other studies, hADSC also adopted perivascular locations. When grafted into the presumptive BA1, 74.6% of the cells were in the outflow tract, the final goal of cardiac neural crest cells, and were also associated with peripheral nerves. This is the first study showing that hADSC could adopt a perineural niche in vivo and were able to recognize cues for neural crest cell migration of the host. Therefore, we propose that xenografts of human cells into chick embryos can reveal novel behaviors of heterogeneous cell populations, such as response to migration cues.

    Over 30 million people worldwide have sickle cell disease (SCD). Emergent and non-emergent surgical procedures in SCD have been associated with relatively increased risks of peri-operative mortality, vaso-occlusive (painful) crisis, acute chest syndrome, post-operative infections, congestive heart failure, cerebrovascular accident and acute kidney injury. Pre-operative assessment must include a careful review of the patient's known crisis triggers, baseline hematologic profile, usual transfusion requirements, pre-existing organ dysfunction and opioid use. Use of preoperative blood transfusions should be selective and decisions individualized based on the baseline hemoglobin, surgical procedure and anticipated volume of blood loss. Intra- and post-operative management should focus on minimizing hypoxia, hypothermia, acidosis, and intravascular volume depletion. Pre- and post-operative incentive spirometry use should be encouraged.

  8. Perioperative acute renal failure.

    PURPOSE OF REVIEW: Recent biochemical evidence increasingly implicates inflammatory mechanisms as precipitants of acute renal failure. In this review, we detail some of these pathways together with potential new therapeutic targets. RECENT FINDINGS: Neutrophil gelatinase-associated lipocalin appears to be a sensitive, specific and reliable biomarker of renal injury, which may be predictive of renal outcome in the perioperative setting. For estimation of glomerular filtration rate, cystatin C is superior to creatinine. No drug is definitively effective at preventing postoperative renal failure. Clinical trials of fenoldopam and atrial natriuretic peptide are, at best, equivocal. As with pharmacological preconditioning of the heart, volatile anaesthetic agents appear to offer a protective effect to the subsequently ischaemic kidney. SUMMARY: Although a greatly improved understanding of the pathophysiology of acute renal failure has offered even more therapeutic targets, the maintenance of intravascular euvolaemia and perfusion pressure is most effective at preventing new postoperative acute renal failure. In the future, strategies targeting renal regeneration after injury will use bone marrow-derived stem cells and growth factors such as insulin-like growth factor-1.

    Microvascular free tissue transfer is a ubiquitous and routine method of restoring anatomic defects. There is a paucity of data regarding the role of perioperative antibiotics in free tissue transfer. We designed a survey to explore usage patterns among microvascular surgeons and thereby define a

    The aim of this study was to compare the perioperative outcomes between renal hilar tumors and non-hilar tumors after robotic-assisted partial nephrectomy (RAPN). A retrospective review of consecutive patients who underwent RAPN from December 2009 to September 2015 at our institution was recruited. Perioperative outcomes including demographic characteristics, perioperative, pathological and renal function outcomes were compared between the hilar group (n = 30) and non-hilar group (n = 170). In characteristics, hilar group was younger (52.4 vs. 58 years, p = 0.04) and had less body mass index (23.7 vs. 25.4 kg/m 2 , p = 0.018). Hilar group had larger tumor size (4.8 vs. 3.7 cm, p = 0.009), higher Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) score (10.7 vs. 8.5, p Hilar tumor was associated with longer operative time (293.6 vs. 240.5 min, p = 0.001) and warm ischemia time (39.9 vs. 21.8 min, p hilar tumor patients had no difference of the change of creatinine and estimated glomerular filtration rate (eGFR) at postoperative 6 and 12 month as compared with non-hilar tumor patients. For renal hilar tumor, RAPN could provide acceptable results of perioperative, pathological and renal function outcome as compared with non-hilar tumor group. Thus RAPN is a safe and effective nephron-sparing surgery technique for renal hilar tumors. Copyright © 2018. Published by Elsevier Taiwan LLC.

    Ten percent of elective surgical patients have diabetes. These patients demonstrate excess perioperative morbidity and mortality. National guidance on the management of adults with diabetes undergoing surgery was published in 2011. We present a region-wide audit of adherence to this guidance across the North Western Deanery. Local teams prospectively collected data according to a locally approved protocol. Pregnant, paediatric and non-elective patients were excluded from this audit. Patient characteristics, type of surgery and aspects of perioperative management were collated and centrally analysed against audit criteria based upon national recommendations. 247 patients with diabetes were identified. HbA1c was recorded in 71% of patients preoperatively; 9% of patients with an abnormal HbA1c were not known by, or referred to, the diabetes team. 17% of patients were admitted the evening preceding surgery. The mean fasting time was 12:20(4) h. Variable rate i.v. insulin infusions (VRIII) were not used when indicated in 11%. Only 8% of patients received the recommended substrate fluid, along with the VRIII (5% glucose in 0.45% saline). Intra-operative capillary blood glucose (CBG) was measured hourly in 56% of patients. Intra-operative CBG was within the acceptable range (4-12 mmol.L(-1)) in 85% of patients. 73% of patients had a CBG measurement performed in recovery. The WHO checklist was used in 95% of patients. National perioperative guidelines were not adhered to in a substantial proportion of patients with diabetes undergoing elective surgery. This study represents a template for future trainee networks. © The Author 2016. Published by Oxford University Press on behalf of the British Journal of Anaesthesia. All rights reserved.

    Perioperative malnutrition has proven to be challenging to define, diagnose, and treat. Despite these challenges, it is well known that suboptimal nutritional status is a strong independent predictor of poor postoperative outcomes. Although perioperative caregivers consistently express recognition of the importance of nutrition screening and optimization in the perioperative period, implementation of evidence-based perioperative nutrition guidelines and pathways in the United States has been quite limited and needs to be addressed in surgery-focused recommendations. The second Perioperative Quality Initiative brought together a group of international experts with the objective of providing consensus recommendations on this important topic with the goal of (1) developing guidelines for screening of nutritional status to identify patients at risk for adverse outcomes due to malnutrition; (2) address optimal methods of providing nutritional support and optimizing nutrition status preoperatively; and (3) identifying when and how to optimize nutrition delivery in the postoperative period. Discussion led to strong recommendations for implementation of routine preoperative nutrition screening to identify patients in need of preoperative nutrition optimization. Postoperatively, nutrition delivery should be restarted immediately after surgery. The key role of oral nutrition supplements, enteral nutrition, and parenteral nutrition (implemented in that order) in most perioperative patients was advocated for with protein delivery being more important than total calorie delivery. Finally, the role of often-inadequate nutrition intake in the posthospital setting was discussed, and the role of postdischarge oral nutrition supplements was emphasized.

  13. Peri-operative communication patterns and media usage--implications for systems design.

    Inter-hospital communication amounts for a great deal of clinicians' work time. While communication is essential to coordinate care, it can also be time consuming and interruptive, and breakdown in communication is an important source of medical errors. One contributor to the interruptive nature of communication is the use of synchronous media, and there is clearly a potential for novel technologies. To assess communication patterns and media usage we performed an ethnographic field study in the peri-operative environment at a Norwegian hospital, as well as interviews with nurses. We analyze the results with regards to choice of media, characteristics of the conversations taking place and meta-messages, and account for addressing, obtrusiveness and information richness in the message exchanges. We find a relative high degree of interruptiveness in communication, and ascribe it to 1) a lack of situational awareness between locations in the peri-operative domain, as well as 2) use of synchronous media. This suggests that design of novel technology for intra-hospital communication should aim at supporting sender-receiver awareness and signaling of availability.

    2014-01-01

    Repeated surveys from Europe, the United States, Australia, and New Zealand have shown that adherence to an evidence-based perioperative care protocol, such as Enhanced Recovery After Surgery (ERAS), has been generally low. It is of great importance to support the implementation of the ERAS protocol as it has been shown to improve outcomes after a number of surgical procedures, including major abdominal surgery. However, despite an increasing awareness of the importance of structured perioperative management, the implementation of this complex protocol has been slow. Barriers to implementation involve both patient- and staff-related factors as well as practice-related issues and resources. To support efficient and successful implementation, further educational and structural measures have to be made on a national or regional level to improve the standard of general health care. Besides postoperative morbidity, biological and physiological variables have been quite commonly reported in previous ERAS studies. Little information, however, has been obtained on cost-effectiveness, long-term outcomes, quality of life and patient-related outcomes, and these issues remain important areas of research for future studies.

    Full Text Available Cardiac surgery associated acute kidney injury (CSA-AKI is associated with poor outcomes including increased mortality, length of hospital stay and cost. The incidence of acute kidney injury (AKI is reported to be between 3-30% depending on the definition of AKI. We designed a multicenter randomized controlled trial to test our hypothesis that a perioperative infusion of sodium bicarbonate during cardiac surgery will attenuate the postoperative rise in creatinine indicating renal injury when compared to a perioperative infusion with normal saline. An interim analysis was performed after data was available on the first 120 participants. A similar number of patients in the two treatment groups developed acute kidney injury (AKI, defined as an increase in serum creatinine the first 48 hours after surgery of 0.3 mg/dl or more. Specifically 14 patients (24% who received sodium chloride (SC and 17 patients (27% who received sodium bicarbonate (SB were observed to develop AKI post surgery, resulting in a relative risk of AKI of 1.1 (95% CI: 0.6-2.1, chi-square p-value=0.68 for patients receiving SB compared to those who received SC . The data safety monitoring board for the trial recommended closing the study early as there was only a 12% probability that the null hypothesis would be rejected. We therefore concluded that a perioperative infusion of sodium bicarbonate failed to attenuate the risk of CSA-AKI.

    Pain of propofol injection has been recalled by many patients as the most painful part of the induction of anesthesia. Tramadol and butorphanol are commonly used analgesics for perioperative analgesia in anesthesia practice. However, their potential to relieve propofol injection pain still needs to be explored. A randomized, double-blind, placebo-controlled study was conducted on 90 American Society of Anesthesiologists I and II adult patients undergoing elective surgery under general anesthesia with propofol as an induction agent. Consecutive sampling technique with random assignment was used to allocate three groups of 30 patients each. Group I patients received an injection of normal saline 3 ml intravenously (placebo) while Group II and Group III patients received injection of tramadol 50 mg and butorphanol 1 mg intravenously, respectively. Before induction of anesthesia patients were asked about the intensity of pain on propofol injection by using visual analog scale (VAS) before the loss of consciousness. Descriptive statistics and analysis of variance with Chi-square test were used to analyze the data. The value of P pain in Group I was observed in 80% of the patients, while it was observed in 23.33% and 20% of patients in Group II and III, respectively. Mean VAS scores were 2.27 ± 1.51, 1.14 ± 1.74, and 1.03 ± 1.72 in Group I, II, and Group III patients, respectively. The incidence of pruritus was 10% and 6.7% and erythema in 13.2% and 6.7% in Group II and III, respectively. Pretreatment with both butorphanol and tramadol significantly reduced pain on propofol injection; however, they exhibited comparable efficacy among each other. Thus, either of these two drugs can be considered for pretreatment to reduce propofol injection pain.

    As surgical complications tend to occur more frequently in the beginning stages of a surgeon's career, knowledge of perioperative complications is important to perform a safe procedure, especially if the surgeon is a novice. We sought to identify and describe perioperative complications and their management in connection with minimally invasive transforaminal lumbar interbody fusion (TLIF). We performed a retrospective chart review of our first 124 patients who underwent minimally invasive TLIF. The primary outcome measure was adverse events during the perioperative period, including neurovascular injury, implant-related complications, and wound infection. Pseudarthroses and adjacent segment pathologies were not included in this review. Adverse events that were not specifically related to spinal surgery and did not affect recovery were also excluded. Perioperative complications occurred in 9% of patients (11/124); including three cases of temporary postoperative neuralgia, two deep wound infections, two pedicle screw misplacements, two cage migrations, one dural tear, and one grafted bone extrusion. No neurologic deficits were reported. Eight complications occurred in the first one-third of the series and only 3 complications occurred in the last two-thirds of the series. Additional surgeries were performed in 6% of patients (7/124); including four reoperations (two for cage migrations, one for a misplaced screw, and one for an extruded graft bone fragment) and three hardware removals (one for a misplaced screw and two for infected cages). We found perioperative complications occurred more often in the early period of a surgeon's experience with minimally invasive TLIF. Implant-related complications were common and successfully managed by additional surgeries in this series. We suggest greater caution should be exercised to avoid the potential complications, especially when surgeon is a novice to this procedure.

    BACKGROUND This study was designed to explore the correlations of hemoglobin level (Hb) and perioperative blood transfusion with the prognosis of gastric cancer (GC). MATERIAL AND METHODS Our study consisted of 210 patients with GC who all received a D2 radical operation. These patients were assigned into three groups: 68 cases in group A (blood transfusion >5 U); 59 cases in group B (blood transfusion blood transfusion). A 5-year follow-up was conducted to evaluate the disease-free survival of the patients. Univariate analysis was performed to reveal the relationship between the indicators and the patients with GC. Kaplan-Meier method was employed to analyze the survival rate of patients, and Cox regression analysis was applied to determine the independent prognostic factors of GC. RESULTS The univariate analysis indicated that age, perioperative blood transfusion amount, TNM staging, maximal tumor diameter, differentiation degree and invasion degree were associated with the prognosis of GC. The Kaplan-Meier curve showed that the disease-free survival rate was declined in the patients who were older, those received more amount of blood transfusion, those in advanced TNM staging, those had larger tumor diameter, and those with decreased degree of differentiation and invasion. Cox regression analysis indicated that perioperative blood transfusion, maximal tumor diameter and invasion degree were the independent factors affecting disease-free survival of the GC. CONCLUSIONS Our study revealed that large amount of perioperative blood transfusion leads to poor prognosis of GC.

    The clinical competence of nursing students in operating room (OR) is an important issue in nursing education. The purpose of this study was to evaluate the psychometric properties of the Persian Perceived Perioperative Competence Scale-Revised (PPCS-R) instrument. This cross-sectional study was conducted across 12 universities in Iran. The psychometric properties and factor structure of the PPCS-R for OR students was examined. Based on the results of factor analysis, seven items were removed from the original version of the scale. The fitness indices of the Persian scale include comparative fit index (CFI) = .90, goodness-of-fit-index (GFI) = .86, adjusted goodness-of-fit index (AGFI) = .90, normed fit index (NFI) = .84, and root mean square error of approximation (RMSEA) = .04. High validity and reliability indicated the scale's value for measuring perceived perioperative competence of Iranian OR students.

    Although it has been widely demonstrated that administration of Daikenchuto (DKT), a traditional Japanese herbal medicine, improves gastrointestinal (GI) motility in patients undergoing abdominal surgery, few studies have investigated the efficacy of perioperative DKT administration for relief of postoperative ileus (PI) in patients undergoing surgery for GI cancer. Therefore, the aim of this study was to investigate whether perioperative administration of DKT relieves PI in patients with GI cancer. We performed a comprehensive electronic search of the literature (Cochrane Library, PubMed, the Web of Science and ICHUSHI) up to December 2016 to identify studies that had shown the efficacy of perioperative DKT administration for relief of PI in patients with GI cancer. To integrate the individual effect of DKT, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI), and heterogeneity was analyzed using I 2 statistics. Seven studies involving a total of 1,134 patients who had undergone GI cancer surgery were included in this meta-analysis. Among 588 patients who received DKT perioperatively, 67 (11.4%) had PI, whereas among 546 patients who did not receive DKT perioperatively, 87 (15.9%) had PI. Perioperative administration of DKT significantly reduced the occurrence of PI (RR=0.58, 95% CI=0.35-0.97, p=0.04, I 2 =48%) in comparison to patients who did not receive DKT or received placebo. The result of this meta-analysis suggests that perioperative administration of DKT relieves PI in patients undergoing surgery for GI cancer.

    Full Text Available Abstract We report here a 44-year-old Moroccan man with resectable gastric adenocarcinoma with overexpression of human epidermal growth factor receptor 2 (HER2 by immunohistochemistry who was treated with trastuzumab in combination with chemotherapy in perioperative setting. He received 3 cycles of neoadjuvant chemotherapy consisting of trastuzumab, oxaliplatin, and capecitabine. Afterwards, he received total gastrectomy with extended D2 lymphadenectomy without spleno-pancreatectomy. A pathologic complete response was obtained with a combination of trastuzumab and oxaliplatin and capecitabine. He received 3 more cycles of trastuzumab containing regimen postoperatively. We conclude that resectable gastric carcinoma with overexpression of the c-erbB-2 protein should ideally be managed with perioperative combination of trastuzumab with chemotherapy. Further research to evaluate trastuzumab in combination with chemotherapy regimens in the perioperative and adjuvant setting is urgently needed.

    : For robot-assisted coronary artery bypass graft interventions, surgeons typically use a preoperative thoracic computed tomography scan of the patient to plan the procedure. However, the cardiac anatomy is prone to changes induced perioperatively in the effort to access the heart and surgical targets, which, in turn, may invalidate the initial plan. This article presents a method to estimate the perioperative heart migration, information which can be further exploited to refine the preoperative surgical plan. : Tracked transesophageal ultrasound images of four patients' hearts were acquired at each stage in the procedure: before lung deflation, after lung deflation, and after both lung deflation and CO2 thoracic insufflation. Anatomic features of interest-the mitral and aortic valves-were identified from each dataset, and their movement between the different procedure stages was recorded and used to estimate the global heart displacement. Moreover, the local morphology of the features of interest was investigated to provide insight on the extent of the deformation the heart has undergone during the workflow. : The study suggested that the heart does undergo substantial displacement-on the order of 10 to 15 mm in each direction (axial, coronal, and sagittal) after lung deflation and CO2 thoracic insufflation. However, no significant differences (P > 0.1) were observed in the morphologic characteristics of the features of interest across the multiple workflow stages, suggesting that local deformations occur at a much smaller scale compared with the global migration. : The quantification of the perioperatively induced changes is critical to track the displacement of the heart and surgical targets. The recorded migration patterns should not be ignored but rather be used to update the surgical plan to better suit the intraoperative environment.

    OBJECTIVE Cervical spinal cord stimulation (cSCS) is used to treat pain of the cervical region and upper extremities. Case reports and small series have shown a relatively low risk of complication after cSCS, with only a single reported case of perioperative spinal cord injury in the literature. Catastrophic cSCS-associated spinal cord injury remains a concern as a result of underreporting. To aid in preoperative counseling, it is necessary to establish a minimum rate of spinal cord injury and surgical complication following cSCS. METHODS The Nationwide Inpatient Sample (NIS) is a stratified sample of 20% of all patient discharges from nonfederal hospitals in the United States. The authors identified discharges with a primary procedure code for spinal cord stimulation (ICD-9 03.93) associated with a primary diagnosis of cervical pathology from 2002 to 2011. They then analyzed short-term safety outcomes including the presence of spinal cord injury and neurological, medical, and general perioperative complications and compared outcomes using univariate analysis. RESULTS Between 2002 and 2011, there were 2053 discharges for cSCS. The spinal cord injury rate was 0.5%. The rates of any neurological, medical, and general perioperative complications were 1.1%, 1.4%, and 11.7%, respectively. There were no deaths. CONCLUSIONS In the largest series of cSCS, the risk of spinal cord injury was higher than previously reported (0.5%). Nonetheless, this procedure remains relatively safe, and physicians may use these data to corroborate the safety of cSCS in an appropriately selected patient population. This may become a key treatment option in an increasingly opioid-dependent, aging population.

    2014-01-01

    Full Text Available Methylphenidate is frequently prescribed for attention deficit hyperactivity disorder, narcolepsy, and other sleep disorders requiring psychostimulants. Our report is based on 2 different clinical experiences of patients with chronic methylphenidate use, undergoing general anesthesia. These cases contrast different strategies of taking versus withholding the drug treatment on the day of surgery. From the standpoint of anesthetic management and patient safety, the concerns for perioperative methylphenidate use are mainly related to cardiovascular stability and possible counteraction of sedatives and anesthetics.

    An American Academy of Neurology practice parameter recommends that long-term prophylactic anti-epileptic drugs (AED) should not be routine in patients with newly diagnosed brain tumors. However, prospective multi-center North American data shows that most newly diagnosed glioma patients receive prophylactic AED. We examined our own peri-operative AED practice patterns in newly-diagnosed patients with malignant glioma to determine if we deviate from published guidelines. A retrospective chart review was performed in adult patients with newly diagnosed malignant gliomas undergoing surgery in southern Alberta between January 2003 and December 2005. Demographic information, AED use, seizure incidence, adverse effects, tumor size, and tumor location were recorded. Of 164 eligible patients, 54 (33%) presented with seizures and all received AED. Prophylactic AED were given to 44 patients (27%). Peri-operative seizures (within 1 week) occurred in two patients without (3%) and no patients with seizure prophylaxis. Adverse AED reactions and adverse effects attributable to seizures were both rare. Prophylactic AED were continued >1 week post-op in 30 patients (18%). Patients receiving prophylactic AED were more likely to have had tumors involving the temporal lobe than those who did not (50 vs. 20%; P < 0.01). Patients receiving peri-operative AED prophylaxis were common, had a trend to reduced peri-operative seizures, and had few adverse effects. However, most of these patients were maintained on prophylactic AED continued beyond the first peri-operative week, contradicting published guidelines. Increased awareness of practice guidelines may help modify AED prescription patterns in malignant glioma patients.

    Full Text Available BACKGROUND: Tranexamic acid (TXA is well-established as a versatile oral, intramuscular, and intravenous (IV antifibrinolytic agent. However, the efficacy of IV TXA in reducing perioperative blood transfusion in spinal surgery is poorly documented. METHODOLOGY: We conducted a meta-analysis of randomized controlled trials (RCTs and quasi-randomized (qi-RCTs trials that included patients for various spinal surgeries, such as adolescent scoliosis surgery administered with perioperative IV TXA according to Cochrane Collaboration guidelines using electronic PubMed, Cochrane Central Register of Controlled Trials, and Embase databases. Additional journal articles and conference proceedings were manually located by two independent researchers. RESULTS: Totally, nine studies were included, with a total sample size of 581 patients. Mean blood loss was decreased in patients treated with perioperative IV TXA by 128.28 ml intraoperatively (ranging from 33.84 to 222.73 ml, 98.49 ml postoperatively (ranging from 83.22 to 113.77 ml, and 389.21 ml combined (ranging from 177.83 to 600.60 ml. The mean volume of transfused packed cells were reduced by 134.55 ml (ranging 51.64 to 217.46 (95% CI; P = 0.0001. Overall, the number of patients treated with TXA who required blood transfusions was lower by 35% than that of patients treated with the comparator and who required blood transfusions (RR 0.65; 95% CI; 0.53 to 0.85; P<0.0001, I(2 = 0%. A dose-independent beneficial effect of TXA was observed, and confirmed in subgroup and sensitivity analyses. A total of seven studies reported DVT data. The study containing only a single DVT case was not combined. CONCLUSIONS: The blood loss was reduced in spinal surgery patients with perioperative IV TXA treatment. Also the percentage of spinal surgery patients who required blood transfusion was significantly decreased. Further evaluation is required to confirm our findings before TXA can be safely used in patients

    Strictureplasty (SP) or miniresective 'bowel-sparing' techniques (MR) can prevent the risk of intestinal stomia and short bowel syndrome in patients affected by Crohn's disease (CD). The aim of this study was to analyze the perioperative morbidity and mortality in 104 of 138 consecutive patients treated for CD complications using bowel-sparing techniques. We also considered the factors that may be related to the risk of perioperative complications and the long-term outcome. One hundred and four patients were treated with SP and/or MR and then included in a prospectively maintained database. The factors claimed to influence perioperative complications were analyzed using Fisher's exact test for categorical observations and the Mann-Whitney U test for continuous variables. A multivariate analysis, using logistic regression, and a long-term time-to-event analysis using the Kaplan-Meier function, were also performed. Perioperative mortality was nil. In relation to the 6 postoperative complications (5.8%), 4 patients underwent minimal bowel resection (MR), 1 a MR with SP, and 1 SP alone. Three of these patients (2.9%) needed reoperation for septic complications, and 3 (2.9%) were treated as outpatients for enterocutaneous fistulas. A correlation (p < 0.05) was found between low serum hemoglobin levels and postoperative complications at univariate and multivariate analyses. The 5-year surgical recurrence-free rate was 75% overall, 73% for patients treated with SP, 78% with MR, and 77% with MR + SP. Postoperative complications are not related to conservative or miniresective surgery even when active disease is present at the resection margins or the site of SP. The higher risk reported for patients with low serum hemoglobin and hematocrit levels suggests that surgeons should consider using preoperative iron and vitamin support, parenteral nutrition and erythropoietin therapy, when necessary, in those cases. Our postoperative morbidity, mortality and long-term surgical

    Full Text Available Background. The best surgical technique for large liver hydatid cysts (LHCs has not yet been agreed on. Objectives. The objective of this study was to examine the role of perioperative endoscopic retrograde cholangiopancreatography (ERCP and biliary drainage in patients with large LHCs. Methods. A 20-year retrospective study of patients with LHCs treated surgically at the University Clinical Center of Kosovo (UCCK. We divided patients into 2 groups based on treatment period: 1981–1990 (Group I and 2001–2010 (Group II. Demographic characteristics (sex, age, the surgical procedure performed, complications rate, and outcomes were compared. Results. Of the 340 patients in our study, 218 (64.1% were female with median age of 37 years (range, 17 to 81 years. 71% of patients underwent endocystectomy with partial pericystectomy and omentoplication, 8% total pericystectomy, 18% endocystectomy with capitonnage, and 3% external drainage. In Group I, 10 patients underwent bile duct exploration and T-tube placement; in Group II, 39 patients underwent bile duct exploration and T-tube placement. In addition, 9 patients in Group II underwent perioperative ERCP with papillotomy. The complication rate was 14.32% versus 6.37%, respectively (P=0.001. Conclusion. Perioperative ERCP and biliary drainage significantly decreased the complication rate and improved outcomes in patients with large LHCs.

    Liver transplantation is widely accepted as an effective therapy of hepatoma. Perioperative dynamic observation of coagulation function is important for graft-receivers. This study was to explore perioperative changes of coagulation functions in the local advanced liver cancer patients who received liver transplantation. Clinical data of 31 local advanced liver cancer patients, underwent liver transplantation from Sep. 2003 to Jan. 2007, were analyzed. Platelet (PLT) counting, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib) and international normalized ratio (INR) before operation, at anhepatic phase and the first week after operation were analyzed to evaluate congulation function. The coagulation functions of most patients were normal before operation. The six parameters varied significantly at anhepatic phase and on most days of the first week after operation when compared with the preoperative levels (Pfunctions of local advanced liver cancer patients shift from hypocoagulatory to hypercoagulatory or normal in perioperative period, therefore, prevention of bleeding should be focused on at anhepatic phase and on 1-2 days after operation while prevention of thrombosis should be focused on after the first week after operation. The degree of liver cirrhosis and Child-Pugh level could help to evaluate postoperative coagulation disorder.

    Paragangliomas are catecholamine-secreting tumors of the paraganglia. Perioperative mortality of children with paraganglioma is high, but preoperative therapy and anesthetic management of paraganglioma resection are controversial in children. The literatures on catecholamine-induced cardiomyopathy are limited to several case reports,with few reports of studies on children. Here we report the anesthetic management of a child with paraganglioma and catecholamine-induced cardiomyopathy, and the possible perioperative anesthesia problems of the paraganglioma resection are discussed. Preoperative and intraoperative anesthetic management of Pheochromocytomas children should follow the same principles as for adults, The most important aspects are the control of blood pressure liability and maintenance of adequate blood volume. Pheochromocytomas patient may have cardiomoyopathy due to myocardial toxicity of excessive circulating catecholamines level. The perioperative management of catecholamine-induced cardiomyopathy should include lowering sympathetic activation by means of α-and β-adrenergic receptor blocker and diuretics administration in case of volume overload.

    Obstructive sleep apnea (OSA) is common in patients undergoing surgery. OSA, known or suspected, has been associated with significant perioperative adverse events, including severe neurologic injury and death. This study was undertaken to assess the legal consequences associated with poor outcomes related to OSA in the perioperative setting. A retrospective review of the legal literature was performed by searching 3 primary legal databases between the years 1991 and 2010 for cases involving adults with known or suspected OSA who underwent a surgical procedure associated with an adverse perioperative outcome. OSA had to be directly implicated in the outcome, and surgical mishaps (i.e., uncontrolled bleeding) were excluded. The adverse perioperative outcome had to result in a lawsuit that was then adjudicated in a court of law with a final decision rendered. Data were abstracted from each case regarding patient demographics, type of surgery, type and location of adverse event, associated anesthetic and opioid use, and legal outcome. Twenty-four cases met the inclusion criteria. The majority (83%) occurred in or after 2007. Patients were young (average age, 41.7 years), male (63%), and had a known diagnosis of OSA (96%). Ninety-two percent of cases were elective with 33.3% considered general procedures, 37.5% were ears, nose and throat procedures for the treatment of OSA, and 29.1% were considered miscellaneous interventions. Complications occurred intraoperatively (21%), in the postanesthesia care unit (33%), and on the surgical floors (46%). The most common complications were respiratory arrest in an unmonitored setting and difficulty in airway management. Immediate adverse outcomes included death (45.6%), anoxic brain injury (45.6%), and upper airway complications (8%). Overall, 71% of the patients died, with 6 of the 11 who suffered anoxic brain injury dying at an average of 113 days later. The use of opioids and general anesthetics was believed to play a role in

    The influence of allogenic blood transfusion on the postoperative outcomes of hepatocellular carcinoma (HCC) surgery remains controversial. This study aims to clarify the clinical impacts of perioperative allogenic blood transfusion on liver resection outcome in HCC patients. We analyzed data collected over 5 years for 642 patients who underwent hepatectomy for HCC at one of the five university hospitals. We investigated the impact of allogenic blood transfusion on postoperative outcome after surgery in all patients and in 74 matched pairs, using a propensity score. Of the 642 patients, 198 (30.8%) received perioperative allogenic blood transfusion (AT group) and 444 (69.2%) did not (non-AT group). Overall survival was lower in the AT group than in the non-AT group in univariate (P blood transfusion was found to be a poor prognostic factor for HCC patients. In this multi-center study, perioperative blood transfusion was an independent factor for poor prognosis after curative surgery for primary HCC in the patient group and in pairs matched by propensity scores.

    To determine whether the perioperative use of hydroxyethyl starch 6% and albumin 5% in elective joint arthroplasties are associated with an increased risk for perioperative complications. Retrospective cohort study of population based data between 2006 and 2013. Data from 510 different hospitals across the United States participating in the Premier Perspective database. 1,051,441 patients undergoing elective total hip and knee arthroplasties. Perioperative fluid resuscitation with hydroxyethyl starch 6% or albumin 5%, or neither. Acute renal failure and thromboembolic, cardiac, and pulmonary complications. Compared with patients who received neither colloid, perioperative fluid resuscitation with hydroxyethyl starch 6% or albumin 5% was associated with an increased risk of acute renal failure (odds ratios 1.23 (95% confidence interval 1.13 to 1.34) and 1.56 (1.36 to 1.78), respectively) and most other complications. A recent decrease in hydroxyethyl starch 6% use was noted, whereas that of albumin 5% increased. Similar to studies in critically ill patients, we showed that use of hydroxyethyl starch 6% was associated with an increased risk of acute renal failure and other complications in the elective perioperative orthopedic setting. This increased risk also applied to albumin 5%. These findings raise questions regarding the widespread use of these colloids in elective joint arthroplasty procedures. © Opperer et al 2015.

    Economic challenges compel pediatric perioperative departments to reduce nonlabor supply costs while maintaining the quality of patient care. Optimization of the supply chain introduces a framework for decision making that drives fiscally responsible decisions. The cost-effective supply chain is driven by implementing a value analysis process for product selection, being mindful of product sourcing decisions to reduce supply expense, creating logistical efficiency that will eliminate redundant processes, and managing inventory to ensure product availability. The value analysis approach is an analytical methodology for product selection that involves product evaluation and recommendation based on consideration of clinical benefit, overall financial impact, and revenue implications.

    2016-06-01

    Antiphospholipid syndrome is an antiphospholipid antibody-mediated prothrombotic state leading to arterial and venous thrombosis. This condition alters routine in-vitro coagulation tests, making results unreliable. Antiphospholipid syndrome patients requiring cardiac surgery with cardiopulmonary bypass present a unique challenge in perioperative anticoagulation management. We describe 3 patients with antiphospholipid syndrome who had successful heart valve surgery at our institution. We have devised an institutional protocol for antiphospholipid syndrome patients, and all 3 patients were managed according to this protocol. An algorithm-based approach is recommended because it improves team work, optimizes treatment, and improves patient outcome. © The Author(s) 2015.

    Inadvertent perioperative hypothermia (IPH) is associated with a range of adverse outcomes. Safe and effective warming techniques exist to prevent IPH; however, IPH remains common. This study aimed to identify factors that anesthesiologists perceive may influence temperature management during the perioperative period. After Research Ethics Board approval, semi-structured interviews were conducted with staff anesthesiologists at a Canadian academic hospital. An interview guide based on the Theoretical Domains Framework (TDF) was used to capture 14 theoretical domains that may influence temperature management. The interview transcripts were coded using direct content analysis to generate specific beliefs and to identify relevant TDF domains perceived to influence temperature management behaviour. Data saturation was achieved after 15 interviews. The following nine theoretical domains were identified as relevant to designing an intervention for practices in perioperative temperature management: knowledge, beliefs about capabilities, beliefs about consequences, reinforcement, memory/attention/decision-making, environmental context and resources, social/professional role/identity, social influences, and behavioural regulation. Potential target areas to improve temperature management practices include interventions that address information needs about individual temperature management behaviour as well as patient outcome (feedback), increasing awareness of possible temperature management strategies and guidelines, and a range of equipment and surgical team dynamics that influence temperature management. This study identified several potential target areas for future interventions from nine of the TDF behavioural domains that anesthesiologists perceive to drive their temperature management practices. Future interventions that aim to close the evidence-practice gap in perioperative temperature management may include these targets.

    Surgery is the cornerstone for clinical management of patients with borderline ovarian tumors (BOT). As these patients have an excellent overall prognosis, perioperative morbidity is the critical point for decision making when the treatment strategy is developed and the primary surgical approach is defined. Clinical and surgical parameters of patients undergoing surgery for primary BOT at our institutions between 1993 and 2008 were analyzed with regard to perioperative morbidity depending on the surgical approach (laparotomy vs. laparoscopy). A total of 105 patients were analyzed (44 with primary laparoscopy [42%], 61 with primary laparotomy [58%]). Complete surgical staging was achieved in 33 patients at primary surgical approach (31.4%) frequently leading to formal indication of re-staging procedures. Tumor rupture was significantly more frequent during laparoscopy compared to laparotomy (29.5% vs. 13.1%, p = 0.038) but no other intraoperative complications were seen in laparoscopic surgery in contrast to 7 of 61 laparotomies (0% vs. 11.5%, p = 0.020). Postoperative complication rates were similar in both groups (19.7% vs. 18.2%, p = 0.848). Irrespective of the surgical approach, surgical management of BOT has acceptable rates of perioperative complications and morbidity. Choice of initial surgical approach can therefore be made independent of complication-concerns. As the recently published large retrospective AGO ROBOT study observed similar oncologic outcome for both approaches, laparoscopy can be considered for staging of patients with BOT if this appears feasible. An algorithm for the surgical management of BOT patients has been developed.

    Forced-air warming is a commonly used warming modality, which has been shown to reduce the incidence of inadvertent perioperative hypothermia (heating mattresses offer a potentially cheaper alternative, however, and one of the research recommendations from the National Institute for Health and Care Excellence was to evaluate such devices formally. We conducted a randomized single-blinded study comparing perioperative hypothermia in patients receiving resistive heating or forced-air warming. A total of 160 patients undergoing non-emergency surgery were recruited and randomly allocated to receive either forced-air warming (n=78) or resistive heating (n=82) in the perioperative period. Patient core temperatures were monitored after induction of anaesthesia until the end of surgery and in the recovery room. Our primary outcome measures included the final intraoperative temperature and incidence of hypothermia at the end of surgery. There was a significantly higher rate of hypothermia at the end of surgery in the resistive heating group compared with the forced-air warming group (P=0.017). Final intraoperative temperatures were also significantly lower in the resistive heating group (35.9 compared with 36.1°C, P=0.029). Hypothermia at the end of surgery in both warming groups was common (36% forced air warming, 54% resistive heating). Our results suggest that forced-air warming is more effective than resistive heating in preventing postoperative hypothermia. NCT01056991. © The Author 2016.

    Giant encephalocele, a rare entity, makes anesthesiologists wary of challenging anesthetic course. Apart from inherent challenges of pediatric anesthesia, the anesthesiologist has to deal with unusual positioning, difficult tracheal intubation, and associated anomalies during the perioperative course. Medical records of 29 children with giant encephalocele, who underwent excision and repair, during a period of 13 years, were retrospectively analyzed. Data pertaining to anesthetic management, perioperative complications, and outcome at discharge were reviewed. The average age at admission was 164 days. Hydrocephalus and delayed milestones were present in 19 (65.5%) and 7 (24.1%) children, respectively. Difficulty in tracheal intubation was encountered, in 15 (51.7%) children. Tracheal intubation was attempted with direct laryngoscopy, most often, in lateral position (24 [82.8%]). Intraoperative hemodynamic and respiratory complications were observed in 9 (31.0%) and 5 (17.2%) children, respectively. Intraoperative hypothermia was observed in 4 (13.8%) children. The average stay in the intensive care unit was 2.7 days and average hospital stay was 11.5 days. The condition at discharge remained same as the preoperative period in 24 children (82.7%), deteriorated in 2 (6.9%), and 3 children (10.3%) died. Management of children with giant encephalocele requires the updated knowledge on possible difficulties encountered during the perioperative period. They need specialized anesthetic care for dealing with difficult tracheal intubation, associated congenital anomalies, unusual positioning, electrolyte abnormalities, hypothermia, and cardiorespiratory disturbances. For securing the airway, we suggest the practice of direct laryngoscopy in lateral position after inhalational induction. Muscle relaxant should be administered only after visualization of the glottis.

    The aim of this study was to evaluate the usefulness of dipyridamole Tl-201 myocardium single photon emission computed tomography (201Tl-SPECT) for predicting perioperative cardiac events in patients with arteriosclerosis obliterans (ASO) and abdominal aortic aneurysm (AAA) undergoing non-cardiac vascular surgery. Methods: Preoperative dipyridamole 201Tl-SPECT imaging in association with clinical risk assessment was performed in 224 consecutive patients (97 ASO and 127 AAA). Results: The patients were classified into three groups, including low-risk (n=173, 77%), intermediate-risk (n=39, 18%), and high-risk (n=12, 5%) groups according to the clinical risk stratification. The prevalence of reversible Tl-201 defect was significantly higher in the high-risk group than that in the low-risk group (83% vs. 14%, p<0.001). In 180 patients who underwent vascular surgery, 9 patients (5.0%) had perioperative cardiac events, including heart failure (n=l), unstable angina (n=2), and other cardiac events such as arrhythmias (n=6). The clinical variables including the clinical risk stratification did not significantly correlate with the perioperative cardiac events. In contrast, the reversible defect on 201Tl-SPECT was the only variable to predict perioperative cardiac events by a stepwise logistic regression analysis (odds ratio 7.0, 95% confidence interval l.7-28.0, p=0.007). It was also a significant predictor of perioperative cardiac events in a subgroup of low risk patients (odds ratio 11.6, 95% confidence interval 2.3-57.4, p=0.004). The sensitivity and specificity of the reversible defect for predicting perioperative cardiac events were 55.6% and 84.8% in all operated patients, and 57.1% and 89.7% in low risk patients, respectively. Conclusions: The preoperative dipyridamole 201Tl-SPECT was useful for predicting perioperative cardiac events in patients with vascular diseases, even in patients identified as having a low risk based on the clinical risk assessment.

    Full Text Available ObjectiveTo investigate the advantage and safety of the concept of fast-track surgery (FTS applied in perioperative patients with biliary calculi and liver cirrhosis. MethodsFifty-two patients undergoing operation for biliary calculi and liver cirrhosis from January 2011 to September 2013 were included in this study. These patients were randomly divided into FTS group (n = 30 and control group (n = 22. Patients in the FTS group received perioperative care measures guided by FTS concept, while patients in the control group received traditional perioperative management measures. The intraoperative situation of patients, time to postoperative recovery of intestinal function, length of postoperative hospital stay, total medical expenses during hospitalization, and postoperative complications were compared between the two groups. Continuous data and categorical data were compared by t-test and χ2 test, respectively. ResultsAs compared with the control group, the FTS group had significantly time to postoperative recovery of intestinal function (t = 2.239, P = 0.045, a significantly shortened length of postoperative stay (t = 4.246, P = 0.038, and significantly reduced total medical expenses during hospitalization (t = 3.045, P = 0.033. No significant difference in postoperative complications was observed between the two groups (P>0.05. ConclusionThe concept of FTS can be safely and effectively applied in perioperative patients with biliary calculi and liver cirrhosis, which can accelerate rehabilitation without increasing the risk of surgery.

    It has been suggested that nutritional status is related to the survival outcomes of cancer patients. The purpose of the current research is to evaluate the importance of the prognosis of various nutritional parameters during the perioperative period in patients with gastric cancer. This study enrolled patients with gastric cancer who underwent D2 gastrectomy at the Department of Surgery, Samsung Medical Center, in 2008. The prognostic significance of nutritional parameters was analyzed, along with other clinical and pathological variables, preoperatively and postoperatively at 3, 6, and 12 months. The total number of patients was 1415. The mean values of nutritional parameters, weight, body mass index (BMI), hemoglobin, total cholesterol, and total lymphocyte count (TLC) decreased significantly over time after surgery. On the contrary, albumin and prognostic nutritional index (PNI) score increased significantly during the postoperative follow-up period. Preoperatively, low BMI (nutritional prognostic indicators. Various perioperative nutritional parameters were confirmed as independent prognostic factors in patients with gastric cancer. Our results imply prognostic benefit from careful nutritional support for patients with poor nutritional parameters.

    Intra and perioperative anticoagulation in patients with heparin induced thrombocytopenia (HIT), candidates for peripheral vascular surgery remains a challenge, as the best alternative to heparin has not yet been established. We evaluated the off-label use of fondaparinux in four patients with HIT, undergoing peripheral vascular surgery procedures. Four patients of whom 3 men of a mean age of 66 years, with proven heparin induced thrombocytopenia (HIT) underwent two axillo-femoral bypasses, one femoro-popliteal bypass and one resection of a splenic artery aneurysm under fondaparinux. No intra or perioperative bleeding or thrombosis of new onset was observed. In the absence of a valid alternative to heparin for intra and perioperative anticoagulation in HIT, several other anticoagulants can be used in an off-label setting. However, no general consensus exist on which should be the one of choice. In this small series fondaparinux appeared to be both safe and effective. These preliminary results seem to justify the off-label use of fondaparinux for intra and perioperative anticoagulation in patients with HIT, candidates for peripheral vascular surgery interventions.

    Full Text Available Background: Although studies have supported the utility of perioperative continuation of antiplatelet drugs, vasodilators, and cerebral ameliorators in most procedures, no study compared total volume of blood loss after total knee arthroplasty (TKA in patients continuing and discontinuing these drugs. Methods: We retrospectively reviewed 266 consecutive patients undergoing TKA, and included 67 patients (25.2% taking antiplatelet drugs, vasodilators, or cerebral ameliorators in this study. All TKAs were performed without a pneumatic tourniquet. The primary outcome was perioperative total blood loss calculated from blood volume and change in hemoglobin. As subgroup analysis, we compared perioperative total blood loss in patients taking antiplatelet drugs. Results: There was no significant difference between the continuing group (n = 38 and discontinuing group (n = 29 in terms of the perioperative total blood loss (1025 ± 364 vs 1151 ± 327 mL, respectively; mean difference 126 mL; 95% confidence interval −45 to 298 mL; P = .15. No major bleeding or thrombotic events occurred in either group until postoperative 3-month follow-up. In patients taking antiplatelet drugs (n = 51, no significant difference was observed in the total blood loss between the continuing group (n = 30 and discontinuing group (n = 21 (1056 ± 287 vs 1151 ± 305 mL, respectively; mean difference 95 mL; 95% confidence interval −75 to 264 mL; P = .27. Conclusions: No significant differences in terms of perioperative total blood loss were observed between patients continuing and discontinuing study drugs. Continuing these drugs may be preferable in the perioperative period of TKA. Keywords: Knee, Primary arthroplasty, Bleeding events, Thrombotic events, Noncardiac surgery

    Full Text Available BACKGROUND: The appropriate use of antibiotics prophylaxis in the prevention and reduction in the incidence of surgical site infection is widespread. This study evaluates the appropriateness of the prescription of antibiotics prophylaxis prior to surgery amongst hospitalized patients in the geographic area of Avellino, Caserta, and Naples (Italy and the factors associated with a poor adherence. METHODS: A sample of 382 patients admitted to 23 surgical wards and undergoing surgery in five hospitals were randomly selected. RESULTS: Perioperative antibiotic prophylaxis was appropriate in 18.1% of cases. The multivariate logistic regression analysis showed that patients with hypoalbuminemia, with a clinical infection, with a wound clean were more likely to receive an appropriate antibiotic prophylaxis. Compared with patients with an American Society of Anesthesiologists (ASA score ≥4, those with a score of 2 were correlated with a 64% reduction in the odds of having an appropriate prophylaxis. The appropriateness of the timing of prophylactic antibiotic administration was observed in 53.4% of the procedures. Multivariate logistic regression model showed that such appropriateness was more frequent in older patients, in those admitted in general surgery wards, in those not having been underwent an endoscopic surgery, in those with a higher length of surgery, and in patients with ASA score 1 when a score ≥4 was chosen as the reference category. The most common antibiotics used inappropriately were ceftazidime, sultamicillin, levofloxacin, and teicoplanin. CONCLUSIONS: Educational interventions are needed to improve perioperative appropriate antibiotic prophylaxis.

    To discuss and explore the levels of support provided to perioperative nurses when participating in multi-organ procurement surgery and the impact to their overall well-being. Assisting within multi-organ procurement surgical procedures has been recognised to impact on the well-being of perioperative nurses leaving little opportunity for them to recover from their participation or to seek available support resources. To date, this area has remained largely unexplored with limited evidence of how nurses manage and cope with these procedures, in addition to the support received in the workplace. A qualitative grounded theory method. The study was informed by perioperative nurses (n = 35) who had previous participatory experience in these surgical procedures from two Australian states. Theoretical sampling directed the collection of data via semistructured in-depth interviews. Data were analysed using the constant comparative method. Three components of levels of support were identified from the data: lacking support within the operating room organisation; surgical team support and access to external professional support. These findings offer new insights into how nurses manage and cope with their participation in organ procurement surgical procedures and what types of support resources can be seen as barriers or enablers to their overall experiences. The need for timely and adequate support is vital to their overall well-being and future participation in organ procurement surgery. These findings have the potential to guide further research with implications for clinical initiatives and practices, looking at new ways of supporting perioperative nurses within the clinical environment both locally and internationally. Healthcare organisations need to acknowledge the emotional, psychosocial and psychological health and well-being of nurses impacted by these surgical procedures and provide appropriate and timely clinical support within the work environment. © 2016

    Full Text Available Objective: During the perioperative period, oral ingestion is changed considerably in esophagectomy patients. The aim of this study was to investigate oral environment modifications in patients undergoing esophageal cancer treatments due to changes in dietary intake and swallowing functions. Material and Methods: Thirty patients who underwent operation for removal of esophageal cancer in Tokushima University Hospital were enrolled in this study. Results: It was found that 1 the flow rate of resting saliva decreased significantly at postoperative period by deprived feeding for one week, although it did not recover several days after oral ingestion began, 2 the accumulation of dental plaque and the number of mutans streptococci in saliva decreased significantly after operation, while both increased relatively quick when oral ingestion began, and 3 the swallowing function decreased significantly in the postoperative period. Conclusions: These results suggest that dental professionals should emphasize the importance of oral health care and provide instructions on plaque control to patients during the perioperative period of esophageal cancer treatment.

    The current practice of perioperative hair removal reflects research-driven changes designed to minimize the risk of surgical wound infection. An aspect of the practice which has received less scrutiny is the clean-up of the clipped hair. This process is critical. The loose fibers represent a potential infection risk because of the micro-organisms they can carry, but their clean-up can pose a logistical problem because of the time required to remove them. Research has demonstrated that the most commonly employed means of clean-up, the use of adhesive tape or sticky mitts, can be both ineffective and time-consuming in addition to posing an infection risk from cross-contamination. Recently published research evaluating surgical clippers fitted with a vacuum-assisted hair collection device highlights the potential for significant practice improvement in the perioperative hair removal clean-up process. These improvements include not only further mitigation of potential infection risk but also substantial OR time and cost savings.

    Hysterectomy is among the most common major surgical procedures performed in women. Approximately 450,000 hysterectomy procedures are performed each year in the United States for benign indications. However, little is known regarding contemporary US hysterectomy trends for women with benign disease with respect to operative technique and perioperative complications, and the association between these 2 factors with patient, surgeon, and hospital characteristics. We sought to describe contemporary hysterectomy trends and explore associations between patient, surgeon, and hospital characteristics with surgical approach and perioperative complications. Hysterectomies performed for benign indications by general gynecologists from July 2012 through September 2014 were analyzed in the all-payer Maryland Health Services Cost Review Commission database. We excluded hysterectomies performed by gynecologic oncologists, reproductive endocrinologists, and female pelvic medicine and reconstructive surgeons. We included both open hysterectomies and those performed by minimally invasive surgery, which included vaginal hysterectomies. Perioperative complications were defined using the Agency for Healthcare Research and Quality patient safety indicators. Surgeon hysterectomy volume during the 2-year study period was analyzed (0-5 cases annually = very low, 6-10 = low, 11-20 = medium, and ≥21 = high). We utilized logistic regression and negative binomial regression to identify patient, surgeon, and hospital characteristics associated with minimally invasive surgery utilization and perioperative complications, respectively. A total of 5660 hospitalizations were identified during the study period. Most patients (61.5%) had an open hysterectomy; 38.5% underwent a minimally invasive surgery procedure (25.1% robotic, 46.6% laparoscopic, 28.3% vaginal). Most surgeons (68.2%) were very low- or low-volume surgeons. Factors associated with a lower likelihood of undergoing minimally

    Despite advances in surgical techniques for spinal metastases, there is often substantial blood loss, resulting in patients requiring blood transfusion during the perioperative period. Allogeneic blood transfusion (ABT) has been the main replenishment method for lost blood. However, the impact of ABT on cancer-related outcomes has been controversial in various studies. We aimed to evaluate the influence of perioperative ABT on disease progression and survival in patients undergoing metastatic spinal tumor surgery (MSTS). We conducted a retrospective study that included 247 patients who underwent MSTS at a single tertiary institution between 2005 and 2014. The impact of using perioperative ABT (either exposure to or quantities of transfusion) on disease progression and survival was assessed using Cox regression analyses while adjusting for potential confounding variables. Of 247 patients, 133 (54%) received ABT. The overall median number of blood units transfused was 2 (range, 0-10 units). Neither blood transfusion exposure nor quantities of transfusion were associated with overall survival (hazard ratio [HR], 1.15 [p = 0.35] and 1.10 [p = 0.11], respectively) and progression-free survival (HR, 0.87 [p = 0.18] and 0.98 [p = 0.11], respectively). The factors that influenced overall survival were primary tumor type and preoperative Eastern Cooperative Oncology Group performance status, whereas primary tumor type was the only factor that had an impact on progression-free survival. This is the first study providing evidence that disease progression and survival in patients who undergo MSTS are less likely to be influenced by perioperative ABT. The worst oncologic outcomes are more likely to be caused by the clinical circumstances necessitating blood transfusion, but not transfusion itself. However, because ABT can have a propensity toward developing postoperative infections, including surgical site infection, the use of patient blood management

    Over the last four decades, as the rates of obesity have increased, so have the challenges associated with its anesthetic management. In the present review, we discuss perioperative anesthesia management issues that are modifiable by the early involvement of the surgical team. We sum up available evidence or expert opinion on issues like patient positioning, postoperative analgesia, and the effect of continuous positive airway pressure (CPAP) ventilation on surgical anastomosis. We also address established predictors of higher perioperative risk and suggest possible management strategies and concerns of obese patients undergoing same day procedures. Finally, a generalized pharmacological model relevant to altered pharmacokinetics in these patients is presented.

    2018-01-01

    Background Postoperative pressure ulcers are important indicators of perioperative care quality, and are serious and expensive complications during critical care. This study aimed to identify perioperative risk factors for postoperative pressure ulcers. Methods This retrospective case-control study evaluated 2,498 patients who underwent major surgery. Forty-three patients developed postoperative pressure ulcers and were matched to 86 control patients based on age, sex, surgery, and comorbidities. Results The pressure ulcer group had lower baseline hemoglobin and albumin levels, compared to the control group. The pressure ulcer group also had higher values for lactate levels, blood loss, and number of packed red blood cell (pRBC) units. Univariate analysis revealed that pressure ulcer development was associated with preoperative hemoglobin levels, albumin levels, lactate levels, intraoperative blood loss, number of pRBC units, Acute Physiologic and Chronic Health Evaluation II score, Braden scale score, postoperative ventilator care, and patient restraint. In the multiple logistic regression analysis, only preoperative low albumin levels (odds ratio [OR]: 0.21, 95% CI: 0.05–0.82; P pressure ulcer development. A receiver operating characteristic curve was used to assess the predictive power of the logistic regression model, and the area under the curve was 0.88 (95% CI: 0.79–0.97; P pressure ulcer development after surgery.

    The relationship between perioperative blood transfusion and long-term survival after curative resection for hepatocellular carcinoma (HCC) remains controversial. The aim of the present study was to investigate the impact of blood transfusion on the long-term prognosis of HCC patients. Patients with primary HCC who underwent a curative hepatectomy from 2003 to 2011 were enrolled and then retrospectively studied. The clinicopathologic characteristics between patients in the blood transfusion and non-transfusion groups were matched using a propensity score matching (PSM) analysis. Univariate and multivariate Cox regression analyses were used to identify whether perioperative blood transfusion affects long-term survival after resection for HCC. A total of 374 patients were enrolled and 113 patients received perioperative transfusions. The 1-, 3- and 5-year disease-free and overall survival rates of the entire cohort were 65.0, 37.3 and 23.9%, and 90.9, 70.7 and 57.5%, respectively. The disease-free and overall survival rates of the blood transfusion group were significantly worse than the disease-free and overall survival rates of the non-transfusion group in the entire cohort (p blood transfusion was not an independent predictor of disease-free and overall survival in the propensity-matched cohort (p = 0.154, p = 0.667). The present study demonstrates that perioperative blood transfusion has no impact on disease-free and overall survival after curative resection for HCC.

    Full Text Available AIM: To evaluate the medical quality of ophthalmologic perioperative period during 2010-2012 in our hospital.METHODS:The relevant data of perioperative period were collected in our hospital during 2010-2012, and the medical quality of perioperative period was evaluated by using the traditional evaluation indexes and adverse events. Whereby, the traditional indicators include vision changes, improving of intraocular pressure, diagnostic accordance rate before and after operation, cure improvement rate, successful rescue rate, and incidence of surgical complications, etc. Adverse events are associated with ophthalmologic perioperative events including pressure sores, postoperative wound infection, drug adverse events, and equipment related adverse events.RESULTS:There were 1483, 1662 and 1931 ophthalmic operations in our hospital in the year 2010, 2011 and 2012, respectively. From traditional index analysis, the proportions of vision improvement for each year were 96.43%, 96.76% and 97.32%, respectively; the rates of intraocular pressure improvement were 87.50%, 85.72% and 90.17%, respectively (P <0.05; the diagnostic accordance rates before and after operation were 99.86%, 99.94% and 99.90%, respectively; cure improvement rates were 99.73%, 99.93% and 99.84%, respectively; the successful rescue rates were 82.98%, 81.46% and 76.66%, respectively; the complications incidence rates were 18.44%, 17.52% and 17.97%, respectively. The negative factor analysis results showed that:among all the patients of ophthalmic surgeries in our hospital during 2010 and 2012, only one case of postoperative wound infection was found in 2011, and also only one case of tumbling in 2010. The adverse drug events for each year were 1 case (0.07%, 2 cases (0.12%, and 4 cases (0.21%, respectively; the medical device adverse events for each year were 3 cases (0.20%, 5 cases (0.30%, and 6 cases (0.31%, respectively.

    The administration of chloride-rich intravenous (IV) fluid and hyperchloraemia have been associated with perioperative renal injury. The aim of this study was to determine whether a comprehensive perioperative protocol for the administration of chloride-limited IV fluid would reduce perioperative renal injury in adults undergoing cardiac surgery. From February 2014 through to December 2015, all adult patients undergoing cardiac surgery within a single academic medical center received IV fluid according to the study protocol. The perioperative protocol governed all fluid administration from commencement of anesthesia through to discharge from the intensive care unit and varied over four sequential periods, each lasting 5 months. In periods 1 and 4 a chloride-rich strategy, consisting of 0.9% saline and 4% albumin, was adopted; in periods 2 and 3, a chloride-limited strategy, consisting of a buffered salt solution and 20% albumin, was used. Co-primary outcomes were peak delta serum creatinine (∆S Cr ) within 5 days after the operation and KDIGO-defined stage 2 or stage 3 acute kidney injury (AKI) within 5 days after the operation. We enrolled and analysed data from 1136 patients, with 569 patients assigned to a chloride-rich fluid strategy and 567 to a chloride-limited one. Compared with a chloride-limited strategy and adjusted for prespecified covariates, there was no association between a chloride-rich perioperative fluid strategy and either peak ∆S Cr , transformed to satisfy the assumptions of multivariable linear regression [regression coefficient 0.03, 95% confidence interval (CI) -0.03 to 0.08); p = 0.39], or stage 2 or 3 AKI (adjusted odds ratio 0.97, 95% CI 0.65-1.47; p = 0.90]. A perioperative fluid strategy to restrict IV chloride administration was not associated with an altered incidence of AKI or other metrics of renal injury in adult patients undergoing cardiac surgery.

    Purpose: To assess the technical feasibility and toxicity of combined operation and perioperative intensity-modulated fractionated interstitial brachytherapy (IMBT) in advanced-stage malignancies involving the skull base with the goal of preserving the patients' senses of sight. Patients and Methods: This series consisted of 18 consecutive cases: ten patients with paranasal sinus carcinomas, five with sarcomas, two with primitive neuroectodermal tumors (PNETs), and one with parotid gland carcinoma. After, in most cases, subtotal surgical resection (R1-R2: carried out so that the patients' senses of sight were preserved), two to twelve (mean five) afterloading plastic tubes were placed into the tumor bed. IMBT was performed with an iridium-192 stepping source in pulsed-dose-rate/high-dose-rate (PDR/HDR) afterloading technique. The total IMBT dose, ranging from 10 to 30 Gy, was administered in a fractionated manner (3-5 Gy/day, 5 days/week). Results: Perioperative fractionated IMBT was performed in 15 out of 18 patients and was well tolerated. Complications that partially prevented or delayed IMBT in some cases included cerebrospinal fluid leakage (twice), meningitis (twice), frontal brain syndrome (twice), afterloading tube displacement (twice), seizure (once), and general morbidity (once). No surgery- or radiation-induced injuries to the cranial nerves or eyes occurred. Median survival times were 33 months after diagnosis and 16 months after combined operation and IMBT. Conclusion: Perioperative fractionated IMBT after extensive but vision-preserving tumor resection seems to be a safe and well-tolerated treatment of advanced/recurrent malignancies involving the skull base. These preliminary state suggest that combined operation and perioperative fractionated IMBT is a palliative therapeutic option in the management of fatal malignancies involving the base of the skull, a strategy which leaves the patients' visual acuity intact.

    Controversy persists surrounding the perceived bleeding risk associated with perioperative clopidogrel use in patients undergoing lower extremity bypass (LEB). The purpose of this study was to examine the LEB bleeding risk and clinical sequelae associated with clopidogrel. All LEBs in the Vascular Quality Initiative (VQI) from 2008 to 2014 were studied. The exposure was perioperative clopidogrel. Primary outcomes were blood transfusion, estimated blood loss ≥500 mL, and reoperation for bleeding. Secondary outcomes included mean operative time, major cardiac events, respiratory complications, infectious complications, and in-hospital mortality. Univariate and multivariable analyses were used to analyze patients on the basis of clopidogrel use and its association with outcomes. Nonparametric test for trend and Mantel-Haenszel methods were used to analyze association of clopidogrel use with blood transfusion and secondary outcomes. Among the LEB cohort (N = 9179), 28% (n = 2544) were taking clopidogrel and 72% (n = 6635) were not. Patients taking clopidogrel were more likely to have coronary disease, prior coronary intervention, abnormal findings on stress test, and aspirin use (P blood transfusion (38% vs 24%; P blood loss ≥500 mL (21% vs 12%; P blood transfusion (odds ratio [OR], 1.8; 95% confidence interval [CI], 1.5-2.1; P 2-unit blood transfusion (OR, 2.0; 95% CI, 1.7-2.5; P blood transfusion amount revealed no remaining effect of clopidogrel on major cardiac events (OR, 1.1; P = .4) or respiratory complications (OR, 1.0; P = .8). Perioperative clopidogrel use in LEB surgery is associated with increased blood loss and blood transfusion. Associated clinical sequelae include increased cardiac and pulmonary complications. Accordingly, surgeons should consider discontinuation of perioperative clopidogrel when it is clinically appropriate unless it is strongly indicated at the time of LEB.

    N-methyl-D-aspartate receptor antagonists have been shown to reduce perioperative pain and opioid use. The authors performed a meta-analysis to determine whether the use of perioperative dextromethorphan lowers opioid consumption or pain scores. PubMed, Web of Science, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Pubget, and EMBASE were searched. Studies were included if they were randomized, double-blinded, placebo-controlled trials written in English, and performed on patients 12 yr or older. For comparison of opioid use, included studies tracked total consumption of IV or intramuscular opioids over 24 to 48 h. Pain score comparisons were performed at 1, 4 to 6, and 24 h postoperatively. Difference in means (MD) was used for effect size. Forty studies were identified and 21 were eligible for one or more comparisons. In 848 patients from 14 trials, opioid consumption favored dextromethorphan (MD, -10.51 mg IV morphine equivalents; 95% CI, -16.48 to -4.53 mg; P = 0.0006). In 884 patients from 13 trials, pain at 1 h favored dextromethorphan (MD, -1.60; 95% CI, -1.89 to -1.31; P dextromethorphan (MD, -0.89; 95% CI, -1.11 to -0.66; P dextromethorphan (MD, -0.92; 95% CI, -1.24 to -0.60; P dextromethorphan use perioperatively reduces the postoperative opioid consumption at 24 to 48 h and pain scores at 1, 4 to 6, and 24 h.

    This systematic review examined the efficacy of perioperative nerve blocks for pain control after hip arthroscopy. The databases Embase, PubMed, and Medline were searched on June 2, 2015, for English-language studies that reported on the use of perioperative nerve blocks for hip arthroscopy. The studies were systematically screened and data abstracted in duplicate. Nine eligible studies were included in this review (2 case reports, 2 case series, 3 non-randomized comparative studies, and 2 randomized controlled trials). In total, 534 patients (534 hips), with a mean age of 37.2 years, who underwent hip arthroscopy procedures were administered nerve blocks for pain management. Specifically, femoral (2 studies), fascia iliaca (2 studies), lumbar plexus (3 studies), and L1 and L2 paravertebral (2 studies) nerve blocks were used. All studies reported acceptable pain scores after the use of nerve blocks, and 4 studies showed significantly lower postoperative pain scores acutely with the use of nerve blocks over general anesthesia alone. The use of nerve blocks also resulted in a decrease in opioid consumption in 4 studies and provided a higher level of patient satisfaction in 2 studies. No serious acute complications were reported in any study, and long-term complications from lumbar plexus blocks, such as local anesthetic system toxicity (0.9%) and long-term neuropathy (2.8%), were low in incidence. The use of perioperative nerve blocks provides effective pain management after hip arthroscopy and may be more effective in decreasing acute postoperative pain and supplemental opioid consumption than other analgesic techniques.

    Several studies suggested that hypertension is positively related to cancer incidence and mortality. In this study, we investigated the association between perioperative blood pressure (BP) and long-term survival outcomes in patients with rectal cancer. This study included a cohort of 358 patients with stages I-III rectal cancer who underwent a curative resection between June 2007 and June 2011. Both pre- and postoperative BPs were measured, by which patients were grouped (low BP: cancer-specific survival (CSS). Univariate analysis showed that patients with high preoperative systolic BP had lower 3-year DFS (67.2% vs. 82.1%, P = 0.041) and CSS rates (81.9% vs. 94.8%, P = 0.003) than patients with low preoperative systolic BP, and the associations remained significant in the Cox multivariate analysis, with the adjusted hazard ratios equal to 1.97 [95% confidence interval (CI) = 1.08-3.60, P = 0.028] and 2.85 (95% CI = 1.00-8.25, P = 0.050), respectively. Similarly, in postoperative evaluation, patients with high systolic BP had significantly lower 3-year CSS rates than those with low systolic BP (78.3% vs. 88.9%, P = 0.032) in univariate analysis. Moreover, high pre- and/or postoperative systolic BP presented as risk factors for CSS in the subgroups of patients who did not have a history of hypertension, with and/or without perioperative administration of antihypertensive drugs. High preoperative systolic BP was an independent risk factor for both CSS and DFS rates, and high postoperative systolic BP was significantly associated with a low CSS rate in rectal cancer patients. Additionally, our results suggest that rectal cancer patients may get survival benefit from BP control in perioperative care. However, further studies should be conducted to determine the association between BP and CSS and targets of BP control.

    Multimodal protocol of perioperative care may enhance recovery after surgery. Based on evidence these new routines of perioperative care changed conventional prescriptions in surgery. To evaluate the results of a multimodal protocol (ACERTO protocol) in elderly patients. Non-randomized historical cohort study was performed at the surgical ward of a tertiary university hospital. One hundred seventeen patients aged 60 and older were submitted to elective abdominal operations under either conventional (n = 42; conventional group, January 2004-June 2005) or a fast-track perioperative protocol named ACERTO (n = 75; ACERTO group, July 2005-December 2007). Main endpoints were preoperative fasting time, postoperative day of re-feeding, volume of intravenous fluids, length of hospital stay and morbidity. The implantation of the ACERTO protocol was followed by a decrease in both preoperative fasting (15 [8-20] vs 4 [2-20] hours, P<0.001) and postoperative day of refeeding (1st [1st-10th] vs 0 [0-5th] PO day; P<0.01), and intravenous fluids (10.7 [2.5-57.5] vs 2.5 [0.5-82] L, P<0.001). The changing of protocols reduced the mean length of hospital stay by 4 days (6[1-43] vs 2[1-97] days; P = 0.002) and surgical site infection rate by 85.7% (19%; 8/42 vs 2.7%; 2/75, P<0.001; relative risk = 1.20; 95% confidence interval = 1.03-1.39). Per-protocol analysis showed that hospital stay in major operations diminished only in patients who completed the protocol (P<0.01). The implementation of multidisciplinary routines of the ACERTO protocol diminished both hospitalization and surgical site infection in elderly patients submitted to abdominal operations.

    Full Text Available Background: Prolonged mechanical ventilation is an important recognized complication occurring during cardiovascular surgery procedures. This study was done to assess the perioperative risk factors related to postoperative pulmonary complications and tracheostomy in women undergoing coronary artery bypass graft with cardiopulmonary bypass. Methods: It was a retrospective study on 5,497 patients, including 31 patients with prolonged ventilatory support and 5,466 patients without it; from the latter group, 350 patients with normal condition (extubated in 6-8 hours without any complication were selected randomly. Possible perioperative risk factors were compared between the two groups using a binary logistic regression model. Results: Among the 5,497 women undergoing coronary artery bypass graft (CABG, 31 women needed prolonged mechanical ventilation (PMV, and 15 underwent tracheostomy. After logistic regression, 7 factors were determined as being independent perioperative risk factors for PMV. Discussion: Age ≥70 years old, left ventricular ejection fraction (LVEF ≤30%, preexisting respiratory or renal disease, emergency or re-do operation and use of preoperative inotropic agents are the main risk factors determined in this study on women undergoing CABG.

    Patients with endocrine diseases such as acromegaly and Cushing's disease have a high prevalence of obstructive sleep apnea (OSA). There is controversy regarding the use of continuous positive airway pressure (CPAP) following transsphenoidal surgery. The aim of this study was to compare the perioperative management and complications, in patients with or without OSA undergoing transsphenoidal surgery. After Research Ethics Board approval, we retrospectively reviewed the charts of all patients who underwent transsphenoidal surgery in our institution from 2006 to 2011. Information collected included patients' demographics, pathology of lesion, history of OSA, anesthetic and perioperative management and incidence of perioperative complications. Patients with sleep study proven OSA were compared with a control group, matched for age, sex and pathology of patients without OSA. Statistical analysis was performed using t-test and Chi-square test and the P transsphenoidal surgery, 105 patients were found to be at risk for OSA by a positive STOP-BANG scoring assessment. Preoperative sleep study testing was positive for OSA in 38 patients. Post-operative hypoxemia (SpO2 transsphenoidal surgery can be treated in most but not all patients with high flow oxygen using the face mask. We were able to safely use CPAP in a very small number of patients but caution is needed to prevent complications. Further prospective studies are needed to determine the safe use of CPAP in patients after transsphenoidal surgery.

    2017-02-01

    In April 2016, Massachusetts General Hospital (MGH) went live with the Epic electronic health records (EHR) system, replacing a variety of EHRs that previously existed in different departments throughout the hospital. At the time of implementation, the Vocera® Badge Communication System, a wireless hands-free communication device distributed to perioperative team members, had increased perioperative communication flow and efficiency. As a quality improvement effort to better understand communication patterns during an EHR go-live, we monitored our Vocera call volume and user volume before, during and after our go-live. We noticed that call volume and user volume significantly increased during our immediate go-live period and quickly returned to baseline levels. We also noticed that call volume increased during periods of unplanned EHR downtime long after our immediate go-live period. When planning the implementation of a new EHR, leadership must plan for and support this critical communication need at the time of the go-live and must also be aware of these needs during unplanned downtime.

    Objective To determine if transfusion affected perioperative and long-term outcome in patients undergoing liver resection for metastatic colorectal cancer. Summary Background Data Blood transfusion produces host immunosuppression and has been postulated to result in adverse outcome for patients undergoing surgical resection of malignancies. Methods Blood transfusion records and clinical outcomes for 1,351 patients undergoing liver resection at a tertiary cancer referral center were analyzed. Results Blood transfusion was associated with adverse outcome after liver resection. The greatest effect was in the perioperative course, where transfusion was an independent predictor of operative mortality, complications, major complications, and length of hospital stay. This effect was dose-related. Patients receiving one or two units or more than two units had an operative mortality of 2.5% and 11.1%, respectively, compared to 1.2% for patients not requiring transfusions. Transfusion was also associated with adverse long-term survival by univariate analysis, but this factor was not significant on multivariate analysis. Even patients receiving only one or two units had a more adverse outcome. Conclusions Perioperative blood transfusion is a risk factor for poor outcome after liver resection. Blood conservation methods should be used to avoid transfusion, especially in patents currently requiring limited amounts of transfused blood products. PMID:12796583

Methods: Computerized literature searches were performed in Medline, Embase, The Cochrane Library, CNKI, CBM, and WANFANG to find randomized controlled trials (RCTs related to the perioperative administration of rhBNP during cardiac surgery starting from the database inception until December 2016. Two researchers independently performed study screening, information extraction, and quality evaluation according to the inclusion/exclusion criteria, and a meta-analysis was performed using RevMan 5.2 software. Results: A total of 12 studies were analyzed, including 12 RCTs and 727 patients. The meta-analysis results indicated that the perioperative administration of rhBNP could reduce the occurrence rate of postoperative complications, length of intensive care unit (ICU stay, length of hospital stay, and serum creatinine (Scr levels, and increase the 24-hour urine volume; however, it did not affect the postoperative mortality rate. Conclusion: The perioperative administration of rhBNP during cardiac surgery was safe and effective, and could improve the prognosis of the patients.

    To examine the national trends of simple prostatectomy (SP) for benign prostatic hyperplasia (BPH) focusing on perioperative outcomes and risk factors for complications. The National Inpatient Sample (2002-2012) was utilized to identify patients with BPH undergoing SP. Analysis included demographics, hospital details, associated procedures, and operative approach (open, robotic, or laparoscopic). Outcomes included complications, length of stay, charges, and mortality. Multivariate logistic regression was used to determine the risk factors for perioperative complications. Linear regression was used to assess the trends in the national annual utilization of SP. The study population included 35,171 patients. Median length of stay was 4 days (interquartile range 3-6). Cystolithotomy was performed concurrently in 6041 patients (17%). The overall complication rate was 28%, with bleeding occurring most commonly. In total, 148 (0.4%) patients experienced in-hospital mortality. On multivariate analysis, older age, black race, and overall comorbidity were associated with greater risk of complications while the use of a minimally invasive approach and concurrent cystolithotomy had a decreased risk. Over the study period, the national use of simple prostatectomy decreased, on average, by 145 cases per year (P = .002). By 2012, 135/2580 procedures (5%) were performed using a minimally invasive approach. The nationwide utilization of SP for BPH has decreased. Bleeding complications are common, but perioperative mortality is low. Patients who are older, black race, or have multiple comorbidities are at higher risk of complications. Minimally invasive approaches, which are becoming increasingly utilized, may reduce perioperative morbidity. Copyright © 2015 Elsevier Inc. All rights reserved.

    The aim of this study was to determine the differences, if any, between application parameters for the Taylor Spatial Frame (TSF) system obtained during surgery under fluoroscopy and after surgery from digital radiography. This retrospective study included 17 extremities of 15 patients (8 male, 7 female; mean age: 21.9 years, range: 10 to 55 years) who underwent TSF after deformity and fracture. Application parameters measured by fluoroscopy at the end of surgery after mounting the fixator were compared with parameters obtained from anteroposterior and lateral digital radiographs taken 1 day after surgery. Fixator was applied to the femur in 8 patients, tibia in 6 and radius in 3. Mean time to removal of the frame was 3.5 (range: 3 to 7) months. Mean perioperative anteroposterior, lateral and axial frame offsets of patients were 9.1 (range: 3 to 20) mm, 18.1 (range: 5 to 37) mm and 95.3 (range: 25 to 155) mm, respectively. Mean postoperative anteroposterior, lateral and axial frame offset radiographs were 11.8 (range: 2 to 30) mm, 18 (range: 6 to 47) mm and 109.5 (range: 28 to 195) mm, respectively. There was no statistically significant difference between the groups (p>0.05). While measurements taken during operation may lengthen the duration in the operation room, fluoroscopy may provide better images and is easier to perform than digital radiography. On the other hand, there is no difference between measurements taken during perioperative fluoroscopy and postoperative digital radiography.

    Full Text Available Background: The perioperative use of epirubicin, cisplatin, and fluorouracil (ECF significantly improves outcomes in patients with gastric and gastro-oesophageal (GO cancers but is cumbersome to administer. Given the equivalence of epirubicin, oxaliplatin, and capectabine (EOX with ECF in advanced setting, we analyzed the compliance, efficacy, and toxicity of perioperative EOX in resectable but locally advanced cancers. Methods: This is a retrospective analysis of prospectively maintained database of patients treated between January 2012 and September 2013 at Tata Memorial Centre. Patients were planned to receive 3# of neoadjuvant (NA and 3# of adjuvant EOX (intravenous epirubicin 50 mg/m 2 D1, oxaliplatin 130 mg/m 2 , on D1, capecitabiine 1250 mg/m 2 D1-21 every 21 days. On completion of NA therapy, patients were planned to undergo gastrectomy and D2 lymphadenectomy. Results: A total of 99 patients (76% males, median age 51 years were treated with perioperative EOX. Preoperatively, 93% patients completed EOX. Post-NA chemotherapy, 4 patients progressed, 1 patient died and 94 were taken up for surgery. Of these, 9 were inoperable and 85 patients underwent radical surgery. Of these, 71% (60/85 were able to complete three cycles of adjuvant EOX. The compliance to complete all 6 cycles of perioperative chemotherapy was 64%. Grade 3 and 4 toxicities were comparable to the MAGIC dataset apart from higher number of diarrhea in our patients. Conclusions: In patients with resectable GO adenocarcinoma, it is possible to deliver the MAGIC-type perioperative chemotherapy with EOX with better compliance, toxicity, and efficacy rates.

    The aim of this study was to evaluate the usefulness of dipyridamole Tl-201 myocardium single photon emission computed tomography ( 201 Tl-SPECT) for predicting perioperative cardiac events in patients with arteriosclerosis obliterans (ASO) and abdominal aortic aneurysm (AAA) undergoing non-cardiac vascular surgery. Preoperative dipyridamole 201 Tl-SPECT imaging in association with clinical risk assessment was performed in 224 consecutive patients (97 ASO and 127 AAA). The patients were classified into three groups, including low-risk (n=173, 77%), intermediate-risk (n=39, 18%), and high-risk (n=12, 5%) groups according to the clinical risk stratification. The prevalence of reversible Tl-201 defect was significantly higher in the high-risk group than that in the low-risk group (83% vs. 14%, p 201 Tl-SPECT was the only variable to predict perioperative cardiac events by a stepwise logistic regression analysis (odds ratio 7.0, 95% confidence interval 1.7-28.0, p=0.007). It was also a significant predictor of perioperative cardiac events in a subgroup of low risk patients (odds ratio 11.6, 95% confidence interval 2.3-57.4, p=0.004). The sensitivity and specificity of the reversible defect for predicting perioperative cardiac events were 55.6% and 84.8% in all operated patients, and 57.1% and 89.7% in low risk patients, respectively. The preoperative dipyridamole 201 Tl-SPECT was useful for predicting perioperative cardiac events in patients with vascular diseases, even in patients identified as having a low risk based on the clinical risk assessment.

    The effect of perineural dexmedetomidine on the time to onset, quality and duration of motor block with ropivacaine has been equivocal and its interaction with general anaesthesia (GA) has not been reported. We assessed the influence of dexmedetomidine added to 0.5% ropivacaine on the characteristics of supraclavicular brachial plexus block and its interaction with GA. In a randomised, double blind study, 36 patients scheduled for orthopaedic surgery on the upper limb under supraclavicular block and GA were divided into either R group (35 ml of 0.5% ropivacaine with 0.5 ml of normal saline [n - 18]) or RD group (35 mL of 0.5% ropivacaine with 50 μg dexmedetomidine [n - 18]). The onset time and duration of motor and sensory blockade were noted. The requirement of general anaesthetics was recorded. Both the groups were comparable in demographic characteristics. The time of onset of sensory block was not significantly different. The proportion of patients who achieved complete motor blockade was more in the RD group. The onset of motor block was earlier in group RD than group R (P quality and duration of supraclavicular brachial plexus block but did not decrease the requirement of anaesthetic agents during GA.

    Advanced heart failure continues to be a leading cause of morbidity and mortality despite improvements in pharmacologic therapy. High demand for cardiac transplantation and shortage of donor organs have led to an increase in the utilization of mechanical circulatory support devices. The total artificial heart is an effective biventricular assist device that may be used as a bridge to transplant and that is being studied for destination therapy. This review discusses the history, indications, and perioperative management of the total artificial heart with emphasis on the postoperative concerns.

    2017-09-01

    The perioperative surgical home (PSH) is a patient-centered, physician-led, multidisciplinary care pathway developed to deliver value-based care based on shared decision-making. Physician and hospital reimbursement will be tied to providing quality care at lower cost, and the PSH model has been used in providing care to patients undergoing lower extremity arthroplasty. The purpose of this review is to discuss the rationale, definition, development, current state, and future direction of the PSH. The PSH model guides the patient throughout the pre and perioperative process and into the postoperative phase. It has been shown in multiple studies to decrease length of stay, improve functional outcomes, allow more home discharges, and lower costs. There is no increase in complications or readmission rates. The PSH pathway is a safe and effective method of providing value-based care to patients undergoing hip and knee arthroplasty.

  11. Perioperative management of patients with pituitary tumours

    Directory of Open Access Journals (Sweden)

    Mary Abraham

    2016-01-01

    Full Text Available Management of pituitary tumours can be very challenging for the anaesthesiologist. These patients require a thorough pre-operative assessment in view of underlying endocrine disturbances, which could cause anatomic and physiological disturbances. This needs to be optimized prior to surgery and the anaesthetic technique planned accordingly. The main intraoperative problems that could be encountered by the anaesthesiologist are airway problems, haemodynamic disturbances and potential for bleeding during surgery. The postoperative concerns are related to the endocrine system and fluid and water balance and this needs to be monitored closely and managed appropriately. The advent of minimally invasive surgery along with neuroimaging has considerably decreased perioperative morbidity and mortality following pituitary surgery. A team approach and close coordination between the endocrinologist, neurosurgeon and anaesthesiologist is imperative for a favourable outcome in patients undergoing pituitary surgery.

    Full Text Available Patients undergoing total knee arthroplasty (TKA report low satisfaction with postoperative pain control. The purpose of this study is to examine if there is a difference in post-operative pain for TKA patients without femoral nerve block receiving an intra-operative pericapsular injection of bupivacaine liposome suspension (EXPAREL; Pacira Pharmaceuticals, Inc., San Diego, California versus a concentrated multi drug cocktail. Seventy TKA patients were randomly assigned to either the bupivacaine liposome or the multi-drug cocktail. Post-operative pain scores, morphine sulfate equivalence consumption values, adverse events, and overall pain control satisfaction scores were collected. Patients reported significantly higher pain level for the cocktail group on post-op day 1 (p < .05 and post-op day 2 (p < .01 versus the bupivacaine liposome group. This same trend was found for morphine sulfate equivalence consumption in the PACU (p < .01 and post-op day 2 (p < .01. Higher satisfaction in pain control (p < .001 and overall experience (p < .01 was also found in the bupivacaine liposome group. Finally, significantly more adverse events were found in the multi-drug group versus the bupivacaine liposome group (p < .05. The study findings demonstrated a non-inferior difference, albeit not a clinically significant difference, in patient-perceived pain scores, morphine sulfate equivalence consumption, adverse events, and overall satisfaction.

    Significant changes were observed on the Hospital Anxiety and Depression Scale (HAD. Modern neurotechnologies measures are necessary to capture all the changes in the symptoms of anxiety before and after the operation for a carotid stenosis. ERPs might be used to select patients with neuromarker of perioperative anxiety, and subsequently to serve in proper psychological care and minimalize the perioperative risk of complications.

    To examine perioperative mortality, long-term survival, causes of death, and prognostic factors for dogs and cats undergoing surgical excision of thymic epithelial tumors (TETs). Multi-institutional case series. Eighty dogs and 32 cats. Follow-up information was obtained for dogs and cats that underwent surgical excision of a TET between 2001 and 2012. Perioperative mortality was 20% in dogs and 22% in cats. No independent risk factors for perioperative mortality were identified. The estimated median survival time for all dogs was 1.69 years (95% CI 0.56-4.32) and the 1- and 4-year survival rates were 55% (95% CI 44-67) and 44% (95% CI 32-56). The estimated median survival time for all cats was 3.71 years (95% CI 0.56-unestimatable) and the 1- and 4-year survival rates were 70% (95% CI 53-87) and 47% (95% CI 0-100). Of animals that survived to discharge, 42% of dogs and 20% of cats eventually died of TET-related causes. The presence of paraneoplastic syndromes (hazard ratio [HR] 5.78, 95% CI 1.64-20.45, P = .007) or incomplete histologic margins (HR 6.09, 95% CI 1.50-24.72, P = .01) were independently associated with decreased survival in dogs. No significant predictors of survival were identified in cats. Conclusions regarding the effect of chemotherapy or radiation therapy could not be made. While there is substantial risk of perioperative death in dogs and cats undergoing surgery for TETs, many animals that survive to discharge have prolonged survival. Survival is significantly decreased in dogs with paraneoplastic syndromes or incomplete histologic margins. © Copyright 2014 by The American College of Veterinary Surgeons.

    The effects of two local anesthetic agents on the diagnostic quality of nuclear medical bone images (NMBIs) of distal parts of the equine fore limb were investigated. Local effects on bone uptake of technetium 99m methylene diphosphonate (99mTc-MDP) 4 and 24 hours after perineural and intraarticular injection of mepivacaine hydrochloride and bupivacaine hydrochloride were evaluated in the carpal and metacarpophalangeal regions of 12 horses and ponies. Neither mepivacaine hydrochloride nor bupivacaine hydrochloride significantly altered the diagnostic quality of the NMBIs. The injection and subsequent action of local anesthetics do not appear to influence local bone uptake of 99mTc-MDP significantly

    This study aimed to quantify the incidence of anesthesia-related and perioperative mortality at a large tertiary pediatric hospital in South Africa. This study included all children aged anesthesia caused the death; (ii) anesthesia may have contributed to or influenced the timing of death; or (iii) anesthesia was entirely unrelated to the death. There were 47 deaths within 30 days of anesthesia prior to discharge from hospital during this 12-month period. The in-hospital mortality within 24 h of administration of anesthesia was 16.5 per 10 000 cases (95% confidence intervals [CI]=7.8-25.1) and within 30 days of administration of anesthesia was 55.3 per 10 000 cases (95% CI=39.5-71.2). Age under 1 year (OR 4.5; 95% CI=2.5-8.0, P=.012) and cardiac surgery and interventional cardiology procedures (OR 2.5; 95% CI=1.2-5.2, Prisk of perioperative mortality. The overall 24-h and 30-day anesthesia-related and in-hospital perioperative mortality rates in our study are comparable with other similar studies from tertiary pediatric centers. © 2017 John Wiley & Sons Ltd.

    Postoperative pneumonia (POP) is common and results in prolonged hospital stays, higher costs, increased morbidity and mortality. However, data on the incidence and risk factors of POP after oral and maxillofacial surgery are rare. This study aims to identify perioperative risk factors for POP after major oral cancer (OC) surgery. Perioperative data and patient records of 331 consecutive subjects were analyzed in the period of April 2014 to March 2016. We individually traced each OC patient for a period to discharge from the hospital or 45 days after surgery, whichever occur later. The incidence of POP after major OC surgery with free flap construction or major OC surgery was 11.6% or 4.5%, respectively. Patient-related risk factors for POP were male sex, T stage, N stage, clinical stage and preoperative serum albumin level. Among the investigated procedure-related variables, incision grade, mandibulectomy, free flap reconstruction, tracheotomy, intraoperative blood loss, and the length of the operation were shown to be associated with the development of POP. Postoperative hospital stay was also significantly related to increased incidence of POP. Using a multivariable logistic regression model, we identified male sex, preoperative serum albumin level, operation time and postoperative hospital stay as independent risk factors for POP. Several perioperative risk factors can be identified that are associated with POP. At-risk oral cancer patients should be subjected to intensified postoperative pulmonary care.

    Perineural spread (PNS) is an unusual mechanism of tumor extension and has been typically reported in squamous cell carcinoma, adenocystic carcinoma, and desmoplastic melanoma. Our group has previously demonstrated PNS in rectal, prostate, bladder, and cervical cancer from the primary site along the autonomic nerves to the major somatic nerves and even intradurally. We believe similar principles apply to renal cell carcinoma (RCC) as well, despite the different anatomy. We performed a retrospective search to identify cases of intradural-extramedullary metastases of RCC caused by PNS. Strict anatomic and imaging inclusion criteria were defined: only lesions located between T6 and L3 were included, and PNS as a potential cause had to be supported by imaging evidence. Although 3 cases of spinal intradural metastases were identified, only one met our strict inclusion criteria. A 61-year-old woman developed a late intradural-extramedullary metastasis of RCC 16 years after the original diagnosis that we believe represents an example of visceral organ PNS. RCC can propagate via PNS from the primary tumor along the autonomic nerves to the aorticorenal, celiac, and mesenteric ganglia and then along the thoracic and lumbar splanchnic nerves to the corresponding spinal nerves and intradurally. We present radiologic evidence together with the review of the literature to support the premise that PNS of RCC not only occurs but goes unrecognized. Copyright © 2016 Elsevier Inc.

    Purpose: To assess the prognostic value of perineural invasion (PNI) for patients treated with dose-escalated external-beam radiation therapy for prostate cancer. Methods and Materials: Outcomes were analyzed for 651 men treated for prostate cancer with EBRT to a minimum dose ≥75 Gy. We assessed the impact of PNI as well as pretreatment and treatment-related factors on freedom from biochemical failure (FFBF), freedom from metastasis (FFM), cause-specific survival (CSS), and overall survival. Results: PNI was present in 34% of specimens at biopsy and was significantly associated with higher Gleason score (GS), T stage, and prostate-specific antigen level. On univariate and multivariate analysis, the presence of PNI was associated with worse FFBF (hazard ratio = 1.7, p <0.006), FFM (hazard ratio = 1.8, p <0.03), and CSS (HR = 1.4, p <0.05) compared with absence of PNI; there was no difference in overall survival. Seven-year rates of FFBF, FFM, and CCS were 64% vs. 80%, 84% vs. 92%, and 91% vs. 95% for those patients with and without PNI, respectively. On recursive partitioning analysis, PNI predicted for worse FFM and CSS in patients with GS 8–10, with FFM of 67% vs. 89% (p <0.02), and CSS of 69% vs. 91%, (p <0.04) at 7 years for those with and without PNI, respectively. Conclusions: The presence of PNI in the prostate biopsy predicts worse clinical outcome for patients treated with dose-escalated external-beam radiation therapy. Particularly in patients with GS 8–10 disease, the presence of PNI suggests an increased risk of metastasis and prostate cancer death.

    Due to the recent advances in radiological diagnostic technology, the role of video-assisted thoracoscopic surgery in thoracic disease has expanded, surgical indication extended to the elderly patients. Cancer patients receiving surgery, radiation therapy and/or chemotherapy may encounter complications in conjunction with the oral cavity such as aspiration pneumonia, surgical site infection and various type of infection. Recently, it is recognized that oral health care management is effective to prevent the postoperative infectious complications, especially pneumonia. Therefore, oral management should be scheduled before start of therapy to prevent these complications as supportive therapy of the cancer treatment. In this background, perioperative oral function management is highlighted in the remuneration for dental treatment revision of 2012,and the importance of oral care has been recognized in generally. In this manuscript, we introduce the several opinions and evidence based on the recent previous reports about the perioperative oral health care and management on thoracic surgery.

    Anatomic parameters determining renal mass complexity have been used in a number of proposed scoring systems despite lack of a critical analysis of their independent contributions. We sought to assess the independent contribution of anatomic parameters on perioperative outcomes of laparoscopic partial nephrectomy (LPN). Preoperative imaging studies were reviewed for 147 consecutive patients undergoing LPN for a single renal mass. Renal mass anatomy was recorded: Size, growth pattern (endo-/meso-/exophytic), centrality (central/hilar/peripheral), anterior/posterior, lateral/medial, polar location. Multivariable models were used to determine associations of anatomic parameters with warm ischemia time (WIT), operative time (OT), estimated blood loss (EBL), intra- and postoperative complications, as well as renal function. All models were adjusted for the learning curve and relevant confounders. Median (range) tumor size was 3.3 cm (1.5-11 cm); 52% were central and 14% hilar. While 44% were exophytic, 23% and 33% were mesophytic and endophytic, respectively. Anatomic parameters did not uniformly predict perioperative outcomes. WIT was associated with tumor size (P=0.068), centrality (central, P=0.016; hilar, P=0.073), and endophytic growth pattern (P=0.017). OT was only associated with tumor size (Panatomic parameter predicted EBL. Tumor centrality increased the odds of overall and intraoperative complications, without reaching statistical significance. Postoperative renal function was not associated with any of the anatomic parameters considered after adjustment for baseline function and WIT. Learning curve, considered as a confounder, was independently associated with reduced WIT and OT as well as reduced odds of intraoperative complications. This study provides a detailed analysis of the independent impact of renal mass anatomic parameters on perioperative outcomes. Our findings suggest diverse independent contributions of the anatomic parameters to the

    Full Text Available Purpose : To evaluate peri-operative multicatheter interstitial pulsed-dose-rate brachytherapy (PDR-BT with an intra-operative catheter placement to boost the tumor excision site in breast cancer patients treated conservatively. Material and methods: Between May 2002 and October 2008, 96 consecutive T1-3N0-2M0 breast cancer patients underwent breast-conserving therapy (BCT including peri-operative PDR-BT boost, followed by whole breast external beam radiotherapy (WBRT. The BT dose of 15 Gy (1 Gy/pulse/h was given on the following day after surgery. Results: No increased bleeding or delayed wound healing related to the implants were observed. The only side effects included one case of temporary peri-operative breast infection and 3 cases of fat necrosis, both early and late. In 11 patients (11.4%, subsequent WBRT was omitted owing to the final pathology findings. These included eight patients who underwent mastectomy due to multiple adverse prognostic pathological features, one case of lobular carcinoma in situ, and two cases with no malignant tumor. With a median follow-up of 12 years (range: 7-14 years, among 85 patients who completed BCT, there was one ipsilateral breast tumor and one locoregional nodal recurrence. Six patients developed distant metastases and one was diagnosed with angiosarcoma within irradiated breast. The actuarial 5- and 10-year disease free survival was 90% (95% CI: 84-96% and 87% (95% CI: 80-94%, respectively, for the patients with invasive breast cancer, and 91% (95% CI: 84-97% and 89% (95% CI: 82-96%, respectively, for patients who completed BCT. Good cosmetic outcome by self-assessment was achieved in 58 out of 64 (91% evaluable patients. Conclusions : Peri-operative PDR-BT boost with intra-operative tube placement followed by EBRT is feasible and devoid of considerable toxicity, and provides excellent long-term local control. However, this strategy necessitates careful patient selection and histological confirmation

    Background Lumbar microdiscectomy is the most commonly performed spine surgery procedure. Over time it has evolved to a minimally invasive procedure. Traditionally patients were advised to restrict activity following lumbar spine surgery. However, post-operative instructions are heterogeneous. The purpose of this report is to assess, by survey, the perioperative care practices of Australasian neurosurgeons in the minimally invasive era. Methods A survey was conducted by email invitation sent to all full members of the Neurosurgical Society of Australasia (NSA). This consisted of 11 multi-choice questions relating to operative indications, technique, and post-operative instructions for lumbar microdiscectomy answered by an electronically distributed anonymized online survey. Results The survey was sent to all Australasian Neurosurgeons. In total, 68 complete responses were received (28.9%). Most surgeons reported they would consider a period of either 4 to 8 weeks (42.7%) or 8 to 12 weeks (32.4%) as the minimum duration of radicular pain adequate to offer surgery. Unilateral muscle dissection with unilateral discectomy was practiced by 76.5%. Operative microscopy was the most commonly employed method of magnification (76.5%). The majority (55.9%) always refer patients to undergo inpatient physiotherapy. Sitting restrictions were advised by 38.3%. Lifting restrictions were advised by 83.8%. Conclusions Australasian neurosurgical lumbar microdiscectomy perioperative care practices are generally consistent with international practices and demonstrate a similar degree of heterogeneity. Recommendation of post-operative activity restrictions by Australasian neurosurgeons is still common. This suggests a role for the investigation of the necessity of such restrictions in the era of minimally invasive spine surgery. PMID:29732417

For physicians, feedback about their clinical practice and outcomes is central to developing both confidence and competence at all stages of their medical careers. Cultural and financial infrastructures need to be in place, and the concept of feedback needs to be readily embraced and encouraged by clinical leadership and other stakeholders. The "buy-in" includes the expectation and view that feedback occurs on a routine basis, and those engaged in the process are both encouraged to participate and held accountable. Feedback must be part of an overarching quality improvement and physician education agenda; it is not meant to be an isolated, fragmented initiative that is typically undermined by lack of resources or systemic barriers to gaining improvement within programs. Effective feedback should be an integral part of clinical practice. Anesthesiologists and other perioperative physicians are identifying specialty-specific indicators that can be used when creating a broader quality improvement agenda. Placing a more immediate formal feedback strategy that focuses on goal-oriented behavior is rapidly becoming a mainstay. Physicians may use their individual feedback reports for reflection and designing personal development plans as lifelong learners and leaders in improving patient care.Keywords: physician education, outcomes measurement, performance improvement, anesthesiology

    The perioperative period is hazardous for patients with neuromuscular disorder. In case of dystrophia myotonica the anaesthesist must avoid all stimuli that may cause a myotonic crisis. If neuromuscular blockade is required, the moderately long-acting vecuronium bromide seems to be the drug of first choice. Blockade and recovery should be monitored. Postoperative pulmonary complications can be minimised by using regional anaesthetic techniques including epidural anaesthesia with local anaesthetics and/or opioids.

    Inhaled corticosteroid (ICS) treatment has been shown to increase the risk of respiratory complications in patients with stable chronic obstructive pulmonary disease (COPD). However, the effects of perioperative ICS treatment on postoperative respiratory complications after lung cancer surgery have not been elucidated. The aim of this study was to investigate whether perioperative ICS treatment would increase the risk of postoperative respiratory complications after lung cancer surgery in patients with COPD. We retrospectively analyzed 174 consecutive COPD patients with non-small-cell lung cancer (NSCLC) who underwent lobectomy or segmentectomy between January 2007 and December 2014. Subjects were grouped based on whether or not they were administered perioperative ICS treatment. Postoperative cardiopulmonary complications were compared between the groups. There were no statistically significant differences in the incidence of postoperative respiratory complications (P = 0.573) between the perioperative ICS treatment group (n = 16) and the control group (n = 158). Perioperative ICS treatment was not significantly associated with postoperative respiratory complications in the univariate or multivariate analysis (odds ratio [OR] = 0.553, 95% confidence interval [CI] = 0.069-4.452, P = 0.578; OR = 0.635, 95% CI = 0.065-6.158, P = 0.695, respectively). Kaplan-Meier analysis showed that there were no statistically significant differences in the postoperative respiratory complications-free durations between the groups (P = 0.566), even after propensity score matching (P = 0.551). There was no relationship between perioperative ICS administration and the incidences of postoperative respiratory complications after surgical resection for NSCLC in COPD patients.

    Perioperative services require the orchestration of multiple staff, space and equipment. Our aim was to identify whether the implementation of operations management and an electronic health record (EHR) improved perioperative performance. We compared 2006, pre operations management and EHR implementation, to 2010, post implementation. Operations management consisted of: communication to staff of perioperative vision and metrics, obtaining credible data and analysis, and the implementation of performance improvement processes. The EHR allows: identification of delays and the accountable service or person, collection and collation of data for analysis in multiple venues, including operational, financial, and quality. Metrics assessed included: operative cases, first case on time starts; reason for delay, and operating revenue. In 2006, 19,148 operations were performed (13,545 in the Main Operating Room (OR) area, and 5603, at satellite locations); first case on time starts were 12%; reasons for first case delay were not identifiable; and operating revenue was $115.8M overall, with $78.1M in the Main OR area. In 2010, cases increased to 25,856 (+35%); Main OR area increased to 13,986 (+3%); first case on time starts improved to 46%; operations outside the Main OR area increased to 11,870 (112%); case delays were ascribed to nurses 7%, anesthesiologists 22%, surgeons 33%, and other (patient, hospital) 38%. Five surgeons (7%) accounted for 29% of surgical delays and 4 anesthesiologists (8%) for 45% of anesthesiology delays; operating revenue increased to $177.3M (+53%) overall, and in the Main OR area rose to $101.5M (+30%). The use of operations management and EHR resulted in improved processes, credible data, promptly sharing the metrics, and pinpointing individual provider performance. Implementation of these strategies allowed us to shift cases between facilities, reallocate OR blocks, increase first case on time starts four fold and operative cases by 35%, and

    This study is initiated to evaluate the effects, costs, and feasibility at the hospital and patient level of an evidence-based strategy to improve the use of Dutch perioperative safety guidelines. Based on current knowledge, expert opinions and expertise of the project team, a multifaceted implementation strategy has been developed. This is a stepped wedge cluster randomized trial including nine representative hospitals across The Netherlands. Hospitals are stratified into three groups according to hospital type and geographical location and randomized in terms of the period for receipt of the intervention. All adult surgical patients meeting the inclusion criteria are assessed for patient outcomes. The implementation strategy includes education, audit and feedback, organizational interventions (e.g., local embedding of the guidelines), team-directed interventions (e.g., multi-professional team training), reminders, as well as patient-mediated interventions (e.g., patient safety cards). To tailor the implementation activities, we developed a questionnaire to identify barriers for effective guideline adherence, based on (a) a theoretical framework for classifying barriers and facilitators, (b) an instrument for measuring determinants of innovations, and (c) 19 semi-structured interviews with perioperative key professionals. Primary outcome is guideline adherence measured at the hospital (i.e., cluster) and patient levels by a set of perioperative Patient Safety Indicators (PSIs), which was developed parallel to the perioperative guidelines. Secondary outcomes at the patient level are in-hospital complications, postoperative wound infections and mortality, length of hospital stay, and unscheduled transfer to the intensive care unit, non-elective readmission to the hospital and unplanned reoperation, all within 30 days after the initial surgery. Also, patient safety culture and team climate will be studied as potential determinants. Finally, a process evaluation is

    Frailty is an age-related, multi-dimensional state of decreased physiologic reserve that results in diminished resiliency and increased vulnerability to stressors. It has proven to be an excellent predictor of unfavorable health outcomes in the older surgical population. There is agreement in recommending that a frailty evaluation should be part of the preoperative assessment in the elderly. However, the consensus is still building with regards to how it should affect perioperative care. The Society for Perioperative Assessment and Quality Improvement (SPAQI) convened experts in the fields of gerontology, anesthesiology and preoperative assessment to outline practical steps for clinicians to assess and address frailty in elderly patients who require elective intermediate or high risk surgery. These recommendations summarize evidence-based principles of measuring and screening for frailty, as well as basic interventions that can help improve patient outcomes. Copyright © 2018 Elsevier Inc.

    Full Text Available Objective: To understand the profile of patients undergoing hip and knee replacement during two years, and to compare the data obtained with the literature. Methods: A total of 323 medical records were reviewed to analyze the perioperative data of patients submitted to hip and knee replacement. Results: Osteoarthritis was the main indication for both procedures and male patients were heavier than females (p < 0.05. Hypertension was the prevalent disease among patients. Blood loss was more frequent in knee surgery than in the hip. Conclusions: The profile of patients undergoing total arthroplasty improved substantially over the past decade due to shorter hospital stay, lower risk of thromboembolic events and no infection as compared to previous reports.

    This study was performed to determine the incidence of perioperative lateral wall fractures with a standard sliding hip screw (SHS) versus a percutaneous compression plate (PCCP) using identical meticulous closed reduction techniques in both groups. Retrospective analysis of a prospective trauma registry. Urban Level I trauma center. Over a 7-year period, 337 patients with intertrochanteric hip fractures were treated with either a SHS or a PCCP at our institution. The PCCP group (Group 1) consisted of 200 patients, of which 141 (71%) had adequate images to be included in the study. The SHS group (Group 2) consisted of 137 patients, of which 100 (73%) had adequate images to be included in the study. Closed reduction and plate application with either a standard sliding hip screw or a percutaneous compression plate for an Orthopaedic Trauma Association 31A1 or 31A2 intertrochanteric hip fracture. : Radiographic evidence of lateral trochanteric wall fracture as measured by intraoperative and perioperative radiographs. There was an overall lateral wall fracture incidence of 20% in the SHS group versus 1.4% in the PCCP group (P fracture types, there was a lateral wall fracture incidence of 29.8% in the SHS group versus 1.9% in the PCCP group (P trochanteric wall fracture compared with the SHS group. This difference became greater when just unstable intertrochanteric fractures were analyzed. An anatomic reduction, combined with a device (PCCP) that uses small-diameter defects in the lateral trochanteric wall, essentially eliminates perioperative lateral trochanteric wall fractures.

    To determine associations between perioperative mortality after surgery for traumatic diaphragmatic hernia, medical records of 17 cats and 79 dogs that underwent diaphragmatic herniorrhaphy were reviewed. The combined perioperative survival rate was 81.3% (88.2% in cats and 79.8% in dogs). Data from acute and chronic cases was assessed separately. Of the acute cases (12 cats and 48 dogs), 10 cats (83.3%) and 38 dogs (79.2%) survived to discharge. Of the chronic cases (5 cats and 31 dogs), 5 cats (100%) and 25 dogs (80.6%) survived to discharge. The time between trauma and surgery, trauma and admission, and admission and surgery were not associated with survival. For cats and dogs, increased duration of anesthesia and surgical procedure were associated with increased mortality (P = 0.0013 and 0.004, respectively). Animals with concurrent soft tissue injuries had a 4.3 times greater odds of mortality than those without soft tissue injury (P = 0.01). Animals with concurrent soft tissue and orthopedic injuries had a 7.3 times greater odds of mortality than those without soft tissue and orthopedic injuries (P = 0.004). Animals that were oxygen dependent had a 5.0 times greater odds of mortality than those that were not (P = 0.02). No other variables were significantly associated with survival. For cats and dogs that underwent surgery for traumatic diaphragmatic hernia, increased anesthetic duration, increased duration of surgical procedure, concurrent soft tissue injuries, concurrent soft tissue and orthopedic injuries, and perioperative oxygen dependence were associated with increased mortality.

    Perioperative management of antithrombotic therapy in patients treated with coronary stents undergoing surgery remains poorly defined. Importantly, surgery represents a common reason for premature treatment discontinuation, which is associated with an increased risk in mortality and major adverse cardiac events. However, maintaining antithrombotic therapy to minimize the incidence of perioperative ischemic complications may increase the risk of bleeding complications. Although guidelines provide some recommendations with respect to the perioperative management of antithrombotic therapy, these have been largely developed according to the thrombotic risk of the patient and a definition of the hemorrhagic risk specific to each surgical procedure, key to defining the trade-off between ischemia and bleeding, is not provided. These observations underscore the need for a multidisciplinary collaboration among cardiologists, anesthesiologists, hematologists and surgeons to reach this goal. The present document is an update on practical recommendations for standardizing management of antithrombotic therapy management in patients treated with coronary stents (Surgery After Stenting 2) in various types of surgery according to the predicted individual risk of thrombotic complications against the anticipated risk of surgical bleeding complications. Cardiologists defined the thrombotic risk using a "combined ischemic risk" approach, while surgeons classified surgeries according to their inherent hemorrhagic risk. Finally, a multidisciplinary agreement on the most appropriate antithrombotic treatment regimen in the perioperative phase was reached for each surgical procedure.

    Full Text Available Postoperative pneumonia (POP is common and results in prolonged hospital stays, higher costs, increased morbidity and mortality. However, data on the incidence and risk factors of POP after oral and maxillofacial surgery are rare. This study aims to identify perioperative risk factors for POP after major oral cancer (OC surgery.Perioperative data and patient records of 331 consecutive subjects were analyzed in the period of April 2014 to March 2016. We individually traced each OC patient for a period to discharge from the hospital or 45 days after surgery, whichever occur later.The incidence of POP after major OC surgery with free flap construction or major OC surgery was 11.6% or 4.5%, respectively. Patient-related risk factors for POP were male sex, T stage, N stage, clinical stage and preoperative serum albumin level. Among the investigated procedure-related variables, incision grade, mandibulectomy, free flap reconstruction, tracheotomy, intraoperative blood loss, and the length of the operation were shown to be associated with the development of POP. Postoperative hospital stay was also significantly related to increased incidence of POP. Using a multivariable logistic regression model, we identified male sex, preoperative serum albumin level, operation time and postoperative hospital stay as independent risk factors for POP.Several perioperative risk factors can be identified that are associated with POP. At-risk oral cancer patients should be subjected to intensified postoperative pulmonary care.

    Enhanced recovery after surgery programs in abdominal surgery are being established progressively. The aim of this study is to evaluate the application of different perioperative care measures in gastric surgery by Spanish surgeons. A descriptive study of 162 surveys answered from September to December 2017 about the management and perioperative care in non-bariatric gastric resection surgery. Antibiotic and antithrombotic prophylaxis are always used by 96.9 and 99.4%, respectively; 62.7% recommend a fasting time for liquids greater than 6hours and only 3% use preoperative carbohydrate drinks. Only 32.4 and 13.3% of subtotal and total gastrectomies are performed laparoscopically; 56.8% use epidural analgesia and drains are always placed by 53.8% in total gastrectomy. Nasogastric tubes are used selectively by 34.6% and always by 11.3%. Bladder catheters are removed during the first 48hours by 77.2%. In the first 24 postoperative hours, less than 20% indicate oral intake and 15.4% mobilize their patients; 49.3% indicate walking after the first 24hours; 30.4% apply a clinical pathway for the care of these patients and only 15.2% used an enhanced recovery after surgery protocol. The implementation of enhanced recovery after surgery measures in non-bariatric gastric resection surgery is not widespread in our country. Copyright © 2018 AEC. Publicado por Elsevier España, S.L.U.

    Transthoracic echocardiography is often used to screen patients prior to non-cardiac surgery to detect conditions associated with perioperative haemodynamic compromise and to stratify risk. However, anaesthetists' use of echocardiography is quite variable. A consortium led by the American College of Cardiology Foundation has developed appropriate use criteria for echocardiography. At Joondalup Hospital in Western Australia, we have used these criteria to order echocardiographic studies in patients attending our anaesthetic pre-admission clinic. We undertook this audit to determine the incidence of significant echocardiographic findings using this approach. In a 22-month period, 606 transthoracic echocardiographic studies were performed. This represented 8.7% of clinic attendees and 1.7% of all surgical patients. In about two-thirds of the patients, the indication for echocardiography was identified on the basis of a telephone screening questionnaire. The most common indications were poor exercise tolerance (27.4%), ischaemic heart disease (20.9%) and cardiac murmurs (16.3%). Over 26% of patients studied had significant cardiac pathology (i.e. moderate or severe echocardiographic findings), most importantly moderate or severe aortic stenosis (8.6%), poor left ventricular function (7.1%), a regional wall motion abnormality (4.3%) or moderate or severe mitral regurgitation (4.1%). Using appropriate use criteria to guide ordering transthoracic echocardiography studies led to a high detection rate of clinically important cardiac pathology in our perioperative service.

    Full Text Available Perioperative chemotherapy increases the overall and progression-free survival of patients suffering from resectable adenocarcinomas of the lower esophagus, gastroesophageal junction and stomach (GEC. Comparing different chemotherapy regimens platin-based protocols with 5-fluorouracil (5-FU/calcium folinate (CF or oral fluoropyrimidines were favorable in terms of efficacy and side-effects. However, there is no consensus which regimen is the most efficacious.42 consecutive patients with resectable GEC (UICC II and III were treated with 3 pre- and postoperative chemotherapy cycles each consisting of epirubicin, oxaliplatin and capecitabine (EOX. We analyzed the overall survival, progression-free survival and toxicity retrospectively in comparison to published data.The median overall survival in our cohort was 29 months and the progression-free survival was 17 months. The most frequent grade 3 and 4 toxicities during preoperative chemotherapy were diarrhea (16.7%, leukocytopenia (9.5% and nausea (9.5%; overall 38.1% of our patients suffered from grade 3 or 4 toxicity. Surgery was carried out in 83% of our patients, 69% of those achieved R0 resection.Comparing our data with the results of previously published randomized trials EOX is at least non-inferior with regard to overall survival, progression-free survival and toxicity. In conclusion, EOX is an appropriate perioperative therapy for patients with resectable GEC.

    Full Text Available Normal saline has traditionally been the resuscitation fluid of choice in the perioperative period of kidney transplantation over balanced potassium solutions. However, the problems arising from hyperchloraemia triggered by the infusion of normal saline have led to studies being conducted that compare this solution with balanced solutions. From this narrative review it can be concluded that the use of balanced crystalloids containing potassium in the perioperative period of kidney transplantation can be considered safe. These solutions do not affect serum potassium levels any more than normal saline, whilst maintaining a better acid–base balance in these patients. Resumen: El suero salino normal (SSN ha sido clásicamente el fluido de resucitación elegido en el periodo perioperatorio del trasplante renal frente a aquellas soluciones balanceadas con potasio. Sin embargo, los problemas derivados de la hipercloremia desencadenada por la infusión de SSN han llevado a la realización de estudios que comparaban esta solución con los fluidos equilibrados. Mediante la presente revisión narrativa se deduce que el uso de cristaloides balanceados con contenido de potasio en su formulación, en el perioperatorio de trasplante renal, puede considerarse seguro. Estas soluciones no provocan una alteración del potasio sérico mayor que la provocada por el SSN y mantienen mejor el equilibrio ácido-base en estos enfermos.

  11. Attacking Postoperative Metastases using Perioperative Oncolytic Viruses and Viral Vaccines

    2014-01-01

    Surgical resection of solid primary malignancies is a mainstay of therapy for cancer patients. Despite being the most effective treatment for these tumors, cancer surgery has been associated with impaired metastatic clearance due to immunosuppression. In preclinical surgery models and human cancer patients, we and others have demonstrated a profound suppression of both natural killer (NK) and T cell function in the postoperative period and this plays a major role in the enhanced development of metastases following surgery. Oncolytic viruses (OV) were originally designed to selectively infect and replicate in tumors, with the primary objective of directly lysing cancer cells. It is becoming increasingly clear, however, that OV infection results in a profound inflammatory reaction within the tumor, initiating innate and adaptive immune responses against it that is critical for its therapeutic benefit. This anti-tumor immunity appears to be mediated predominantly by NK and cytotoxic T cells. In preclinical models, we found that preoperative OV prevents postoperative NK cell dysfunction and attenuates tumor dissemination. Due to theoretical safety concerns of administering live virus prior to surgery in cancer patients, we characterized safe, attenuated versions of OV, and viral vaccines that could stimulate NK cells and reduce metastases when administered in the perioperative period. In cancer patients, we observed that in vivo infusion with oncolytic vaccinia virus and ex vivo stimulation with viral vaccines promote NK cell activation. These preclinical studies provide a novel and clinically relevant setting for OV therapy. Our challenge is to identify safe and promising OV therapies that will activate NK and T cells in the perioperative period preventing the establishment of micrometastatic disease in cancer patients.

    Purpose: To analyze patterns of failure in patients with head-and-neck cutaneous squamous cell carcinoma (HNCSCC) and clinical/radiologic evidence of perineural invasion (CPNI), in order to define neural clinical target volume (CTV) for treatment planning. Methods and Materials: Patients treated with three-dimensional (3D) conformal or intensity-modulated radiotherapy (IMRT) for HNCSCC with CPNI were included in the study. A retrospective review of the clinical charts, radiotherapy (RT) plans and radiologic studies has been conducted. Results: Eleven consecutive patients with HNCSCCs with CPNI were treated from 2000 through 2007. Most patients underwent multiple surgical procedures and RT courses. The most prevalent failure pattern was along cranial nerves (CNs), and multiple CNs were ultimately involved in the majority of cases. In all cases the involved CNs at recurrence were the main nerves innervating the primary tumor sites, as well as their major communicating nerves. We have found several distinct patterns of disease spread along specific CNs depending on the skin regions harboring the primary tumors, including multiple branches of CN V and VII. These patterns and the pertinent anatomy are detailed in the this article. Conclusions: Predictable disease spread patterns along cranial nerves supplying the primary tumor sites were found in this study. Awareness of these patterns, as well as knowledge of the relevant cranial nerve anatomy, should be the basis for CTV definition and delineation for RT treatment planning.

    2013-03-01

    Full Text Available Objective: Traditional neurosurgical practice calls for administration of peri-operative stress-dose steroids for sellar-suprasellar masses undergoing operative treatment. This practice is considered critical to prevent peri-operative complications associated with hypoadrenalism, such as hypotension and circulatory collapse. However, stress-dose steroids complicate the management of these patients. It has been our routine practice to use stress steroids during surgery only if the patient has clinical or biochemical evidence of hypocortisolism pre-operatively. We wanted to be certain that this practice was safe.Methods: We present our retrospective analysis from a consecutive series of 114 operations in 109 patients with sellar and/or suprasellar tumors, the majority of whom were managed without empirical stress-dose steroid coverage. Only patients who were hypoadrenal pre-operatively or who had suffered apoplexy were given stress dose coverage during surgery. We screened for biochemical evidence of hypoadrenalism as a result of surgery by measuring immediate post-operative AM serum cortisol levels.Results: There were no adverse events related to the selective use of cortisol replacement in this patient population. Conclusions: Our experience demonstrates that selective use of corticosteroid replacement is safe; it simplifies the management of the patients, and has advantages over empiric dogmatic steroid coverage.

    Perioperative preparations such as operating room setup, patient and equipment positioning, and operating port placement are essential to operative success in minimally invasive surgery. We developed an immersive virtual reality-based training system (REMIS) to provide residents (and other health professionals) with training and evaluation in these perioperative skills. Our program uses the qualities of immersive VR that are available today for inclusion in an ongoing training curriculum for surgical residents. The current application consists of a primary platform for patient positioning for a laparoscopic cholecystectomy. Having completed this module we can create many different simulated problems for other procedures. As a part of the simulation, we have devised a computer-driven real-time data collection system to help us in evaluating trainees and providing feedback during the simulation. The REMIS program trains and evaluates surgical residents and obviates the need to use expensive operating room and surgeon time. It also allows residents to train based on their schedule and does not put patients at increased risk. The method is standardized, allows for repetition if needed, evaluates individual performance, provides the possible complications of incorrect choices, provides training in 3-D environment, and has the capability of being used for various scenarios and professions.

    Type II thyroplasty (TPII) is one of the surgical options offered in the management of adductor spasmodic dysphonia (AdSD); however, there have been no detailed reports of its safety and associated complications during the perioperative period. Our aim was to assess the complications and safety of TPII. TPII was performed for consecutive 15 patients with AdSD from April 2012 through May 2014. We examined retrospectively the perioperative complications, the degree of surgical invasion, and recovery process from surgery. All patients underwent successful surgery under only local anesthesia. Vocal fold erythema was observed in 14 patients and vocal fold edema in 10 patients; however, all of them showed complete resolution within 1 month. No patient experienced severe complications such as acute airway distress or hemorrhage. Fourteen patients were able to have oral from the 1st postoperative morning, with the remaining patient able to have oral intake from the 2nd postoperative day. In addition, no patient experienced aspiration postoperatively. In conclusion, only minor complications were observed in association with TPII in this study. No dysphagia was observed postoperatively, which is an advantage over other treatments. The results of our study suggest that TPII is a safe surgical treatment for AdSD.

    High volume spay-neuter (spay-castration) clinics have been established to improve population control of cats and dogs to reduce the number of animals admitted to and euthanazed in animal shelters. The rise in the number of spay-neuter clinics in the USA has been accompanied by concern about the quality of animal care provided in high volume facilities, which focus on minimally invasive, time saving techniques, high throughput and simultaneous management of multiple animals under various stages of anesthesia. The aim of this study was to determine perioperative mortality for cats and dogs in a high volume spay-neuter clinic in the USA. Electronic medical records and a written mortality log were used to collect data for 71,557 cats and 42,349 dogs undergoing spay-neuter surgery from 2010 to 2016 at a single high volume clinic in Florida. Perioperative mortality was defined as deaths occurring in the 24h period starting with the administration of the first sedation or anesthetic drugs. Perioperative mortality was reported for 34 cats and four dogs for an overall mortality of 3.3 animals/10,000 surgeries (0.03%). The risk of mortality was more than twice as high for females (0.05%) as for males (0.02%) (P=0.008) and five times as high for cats (0.05%) as for dogs (0.009%) (P=0.0007). High volume spay-neuter surgery was associated with a lower mortality rate than that previously reported in low volume clinics, approaching that achieved in human surgery. This is likely to be due to the young, healthy population of dogs and cats, and the continuous refinement of techniques based on experience and the skills and proficiency of teams that specialize in a limited spectrum of procedures.

    Recent animal studies have demonstrated that hyperlipidemia is associated with poor tendon-bone healing after rotator cuff repair; however, these findings have not been substantiated in human studies. To examine any association between hyperlipidemia and the failure of arthroscopic rotator cuff repair requiring revision surgery and to investigate whether the use of statin lipid-lowering agents had any influence on observed associations. Cohort study; Level of evidence, 3. From a national insurance database, patients who underwent arthroscopic rotator cuff repair with perioperative lipid levels (total cholesterol, low-density lipoprotein [LDL], and triglycerides) recorded were reviewed. For each lipid test, patients were stratified into normal, moderate, and high groups based on published standards. For the total cholesterol and LDL cohorts, a subgroup analysis of patients stratified by statin use was performed. The primary outcome measure was ipsilateral revision rotator cuff surgery, including revision repair or debridement. A logistic regression analysis controlling for patient demographics and comorbidities was utilized for comparison. There were 30,638 patients included in the study. The rate of revision rotator cuff surgery was significantly increased in patients with moderate (odds ratio [OR], 1.20; 95% CI, 1.03-1.40; P = .022) and high total cholesterol levels (OR, 1.36; 95% CI, 1.10-1.55; P = .006) compared with patients with normal total cholesterol levels perioperatively. Within each of these groups, patients without statin use had significantly higher rates of revision surgery, while those with statin prescriptions did not. The absolute risk reduction for statin use ranged from 0.24% to 1.87% when stratified by the total cholesterol level, yielding a number needed to treat from 54 to 408 patients. The rate of revision surgery was significantly increased in patients with moderate (OR, 1.24; 95% CI, 1.10-1.41; P = .001) and high LDL levels (OR, 1.46; 95

    Previous studies demonstrated that intra-operative fluoroscopic 3D-imaging (3D-imaging) in calcaneal fracture surgery is promising to prevent revision surgery and save costs. However, these studies limited their focus to corrections performed after 3D-imaging, thereby neglecting corrections after intra-operative fluoroscopic 2D-imaging (2D-imaging). The aim of this study was to assess the effects of additional 3D-imaging on intra-operative corrections, peri-operative imaging used, and patient-relevant outcomes compared to 2D-imaging alone. In this before-after study, data of adult patients who underwent open reduction and internal fixation (ORIF) of a calcaneal fracture between 2000 and 2014 in our level-I Trauma center were collected. 3D-imaging (BV Pulsera with 3D-RX, Philips Healthcare, Best, The Netherlands) was available as of 2007 at the surgeons' discretion. Patient and fracture characteristics, peri-operative imaging, intra-operative corrections and patient-relevant outcomes were collected from the hospital databases. Patients in whom additional 3D-imaging was applied were compared to those undergoing 2D-imaging alone. A total of 231 patients were included of whom 107 (46%) were operated with the use of 3D-imaging. No significant differences were found in baseline characteristics. The median duration of surgery was significantly longer when using 3D-imaging (2:08 vs. 1:54 h; p = 0.002). Corrections after additional 3D-imaging were performed in 53% of the patients. However, significantly fewer corrections were made after 2D-imaging when 3D-imaging was available (Risk difference (RD) -15%; 95% Confidence interval (CI) -29 to -2). Peri-operative imaging, besides intra-operative 3D-imaging, and patient-relevant outcomes were similar between groups. Intra-operative 3D-imaging provides additional information resulting in additional corrections. Moreover, 3D-imaging probably changed the surgeons' attitude to rely more on 3D-imaging, hence a 15%-decrease of

    Although most people who inject drugs (PWID) report receiving assistance during injection initiation events, little research has focused on risk factors among PWID for providing injection initiation assistance. We therefore sought to determine the influence of non-injection drug use among PWID on their risk to initiate others. We used generalized estimating equation (GEE) models on longitudinal data among a prospective cohort of PWID in Tijuana, Mexico (Proyecto El Cuete IV), while controlling for potential confounders. At baseline, 534 participants provided data on injection initiation assistance. Overall, 14% reported ever initiating others, with 4% reporting this behavior recently (i.e., in the past 6 months). In a multivariable GEE model, recent non-injection drug use was independently associated with providing injection initiation assistance (adjusted odds ratio [AOR] = 2.42, 95% confidence interval [CI] = 1.39-4.20). Further, in subanalyses examining specific drug types, recent non-injection use of cocaine (AOR = 9.31, 95% CI = 3.98-21.78), heroin (AOR = 4.00, 95% CI = 1.88-8.54), and methamphetamine (AOR = 2.03, 95% CI = 1.16-3.55) were all significantly associated with reporting providing injection initiation assistance. Our findings may have important implications for the development of interventional approaches to reduce injection initiation and related harms. Further research is needed to validate findings and inform future approaches to preventing entry into drug injecting.

    Perioperative chemotherapy combined with surgery for liver metastases is considered an active strategy in metastatic colorectal cancer (CRC). However, its impact on initially unresectable, previously untreated advanced CRC, regardless of concurrent metastases, remains to be clarified. A Phase II study was conducted to evaluate the safety and efficacy of perioperative FOLFOX4 plus bevacizumab for initially unresectable advanced CRC. Patients with previously untreated advanced colon or rectal cancer initially diagnosed as unresectable advanced CRC (TNM stage IIIb, IIIc, or IV) but potentially resectable after neoadjuvant chemotherapy (NAC) were studied. Preoperatively, patients received six cycles of NAC (five cycles of neoadjuvant FOLFOX4 plus bevacizumab followed by one cycle of FOLFOX4 alone). The interval between the last dose of bevacizumab and surgery was at least 5 weeks. Six cycles of adjuvant FOLFOX4 plus bevacizumab were given after surgery. The completion rate of NAC and feasibility of curative surgery were the primary endpoints. An interim analysis was performed at the end of NAC in the 12th patient to assess the completion rate of NAC. The median follow-up time was 56 months. The characteristics of the patients were as follows: sex, eight males and four females; tumor location, sigmoid colon in three, ascending colon in one, and rectum (above the peritoneal reflection) in eight; stage, III in eight and IV in four (liver or lymph nodes). All patients completed six cycles of NAC. There were no treatment-related severe adverse events or deaths. An objective response to NAC was achieved in nine patients (75%), and no disease progression was observed. Eleven patients underwent curative tumor resection, including metastatic lesions. In December 2012, this Phase II study was terminated because of slow registration. Perioperative FOLFOX4 plus bevacizumab is well tolerated and has a promising response rate leading to curative surgery, which offers a survival

    Objective: To categorize the significant complications occurred in the perioperative period of peripheral vascular interventions and to analyze their causes, outcomes and managements in order to make a further understanding of the cause of occurrence and to improve the handling ability. Methods: Over the past five years a total of 1620 consecutive peripheral vascular interventions were carried out in our institute. Significant complications, which occurred in the perioperative period, and the clinical data were carefully examined. The occurrence, treatment, consequence and final outcome of each complication were retrospectively analyzed. Results: Of 1620 consecutive peripheral interventional procedures, significant complication which developed during the operation or within one week after the treatment was seen in 76 (4.69%). The significant complications could be classified into twelve kinds. After proper management most complications were cured without leaving any sequelae. Nevertheless, in some patients permanent damages such as paraplegia, lower limb paralysis, necrosis of gluteus, etc. were left over. Death occurred in six patients. Of the six patients, four died of concomitant hepatic failure and agranulocytosis, one of retroperitoneal hematoma and hemoperitoneum, and another one of pulmonary embolism. Conclusion: (1) Significant complications may occur in most peripheral vascular interventional therapies, which, in most cases, are mainly related to the insufficient understanding of the disease and improper manipulation. (2) A comprehensive and solid fundamental knowledge of the disease, strictly following the indications and careful handling the operation are the key points to reduce the occurrence of severe complications in the perioperative period of peripheral vascular interventions.

    To evaluate the perioperative outcomes of zero ischemia radiofrequency ablation-assisted tumor enucleation. Patients undergoing zero ischemia radiofrequency ablation-assisted tumor enucleation were retrospectively identified from July 2008 to March 2013. The tumor was enucleated after RFA treatment. R.E.N.A.L., PADUA and centrality index (C-index) score systems were used to assess each tumor case. We analyzed the correlation of perioperative outcomes with these scores. Postoperative complications were graded with Clavien-Dindo system. Multivariate logistic regression analyses were used to assess risk of complications. Among 182 patients assessed, median tumor size, estimated blood loss, hospital stay and operative time were 3.2 cm (IQR 2.8-3.4), 80 ml (IQR 50-120), 7 days (IQR 6-8) and 100 min (IQR 90-120), respectively. All three scoring systems were strongly correlated with estimated blood loss, hospital stay and operative time. We found 3 (1.6%) intraoperative and 23 (12.6%, 13 [7.1%] Grade 1 and 10 [5.5%] Grade 2 & 3a) postoperative complications. The median follow-up was 55.5 months (IQR 45-70). Additionally, the complexities of R.E.N.A.L., PADUA and C-index scores were significantly correlated with complication grades (P radiofrequency ablation-assisted tumor enucleation is considered an effective nephron-sparing treatment. Scoring systems could be useful for predicting perioperative outcomes of radiofrequency ablation-assisted tumor enucleation.

    National differences exist in the outcome of elective abdominal aortic aneurysm (AAA) repair. The role of case mix variation was assessed based on an international vascular registry collaboration. All elective AAA repairs with aneurysm size data in the Vascunet database in the period 2005-09 were included. AAA size and peri-operative outcome (crude and age adjusted mortality) were analysed overall and in risk cohorts, as well as per country. Glasgow Aneurysm Score (GAS) was calculated as risk score, and patients were stratified in three equal sized risk cohorts based on GAS. Predictors of peri-operative mortality were analysed with multiple regression. Missing data were handled with multiple imputation. Patients from Australia, Finland, Hungary, Norway, Sweden and the UK (n = 5,895) were analysed; mean age was 72.7 years and 54% had endovascular repair (EVAR). There were significant variations in GAS (lowest = Finland [75.7], highest = UK [79.4], p for comparison of all regions 82. Of those with a GAS >82, 8.4% of men and 20.8% of women had an AAA case selection for elective AAA repair, including variations in AAA size and patient risk profile. These differences partly explain the variations in peri-operative mortality. Further audit is warranted to assess the underlying reasons for the regional variation in case-mix.

    This study examined the effects of WeChat-assisted perioperative instructions for parents whose children were to undergo herniorrhaphy. A randomized controlled trial was conducted in a day surgery center in China. Participants were randomly assigned to the intervention (WeChat) group (n = 209) and the control (Leaflet) group (n = 209). The primary outcomes of this study were parents' knowledge regarding hernia and rate of cancellation of children's surgery. The secondary outcomes were the rate of lost-to-follow-up and the rate of complications and adverse events during the seventh postoperative follow-up day. There was a significant difference in the rate of cancelling the surgery and the mean knowledge score between the WeChat group and leaflet groups. The lost-to-follow-up rate was significantly lower in the WeChat group (0.54%) than in the leaflet group (3.66%). The incidence of postoperative complications were higher in the control group. WeChat-assisted perioperative care instructions enhanced parents' knowledge on perioperative instructions and promoted the preparation of their children for day surgery resulting in lower rate of cancelling the surgery. WeChat has the ability to expand health services outside the hospital confines and could be used as an important low-cost health educational medium in China. Copyright © 2018 Elsevier B.V.

    Full Text Available [english] Background: Anticoagulation is a crucial element in microsurgery. Although various clinical studies and international surveys have revealed that anticoagulation strategies can vary and result in similar outcomes, anticoagulative regimen are far away from standardization. In Germany and german speaking countries standardized anticoagulation protocols concerning free flap surgery do not exist so far. Methods: To evaluate the current practice of clinics in Germany, Austria and Switzerland with specialization in microsurgery we performed a questionnaire surveying the perioperative regimen of anticoagulant and antiplatelet therapy in free flap surgery. The microsurgeons were interrogated on several anticoagulant, rheologic and antiplatelet medications, their dosage and perioperative frequency of application pre-, intra- and postoperative.Results: The questionnaire revealed that the used antithrombotic and perioperative regimens varied from department to department presumably based on the personal experience of the surgeon. Multiple approaches are used with a wide range of anticoagulants used either alone or in combination, with different intervals of application and different dosages. Conclusion: Therefore consensus meetings should be held in future leading to conduct prospective multicenter studies with formulation of standardized anticoagulative and perioperative protocols in microsurgery reducing flap failure to other than pharmacologic reasons.[german] Hintergrund: Die Antikoagulation stellt ein zentrales Element in der Mikrochirurgie dar.

    Provision of liquid enteral nutrition (LEN) during the perioperative period is standard practice for rodents undergoing bariatric surgery, yet these diets are associated with several challenges, including coagulation of the liquid diet within the delivery system and decreased postoperative consumption. We investigated the use of a commercially available high-calorie dietary gel supplement (DG) as an alternative food source for mice during the perioperative period. C57BL/6J male mice were fed high-fat diet for 8 to 10 wk prior to surgery. The study groups were: vertical sleeve gastrectomy (VSG) +DG, VSG+LEN, sham surgery+DG, and sham+LEN. Food and water intakes, body weight, and body fat composition was monitored throughout the study. Mice that received DG lost significantly more weight preoperatively than those fed LEN. However, during the postoperative period, body weight, body fat composition, and water and caloric intake were similar among all experimental diet groups. Three mice in the VSG+LEN group were euthanized due to clinical illness during the course of the study. In summary, feeding a high-calorie DG to mice undergoing VSG surgery is a viable alternative to LEN, given that DG does not significantly affect the surgical model of weight loss or result in adverse clinical outcomes. We recommend additional metabolic characterization of DG supplementation to ensure that this novel diet does not confound specific research goals in the murine VSG model.

    Although the evidence strongly supports perioperative glycemic control among cardiac surgical patients, there is scant literature to describe the practical application of such a protocol in the complex ICU environment. This paper describes the use of the Lean Six Sigma methodology to implement a perioperative insulin protocol in a cardiac surgical intensive care unit (CSICU) in a large academic hospital. A preintervention chart audit revealed that fewer than 10% of patients were admitted to the CSICU with glucose <200 mg/dL, prompting the initiation of the quality improvement project. Following protocol implementation, more than 90% of patients were admitted with a glucose <200 mg/dL. Key elements to success include barrier analysis and intervention, provider education, and broadening the project scope to address the intraoperative period.
