  2. [Mutual influence and development between Gastrointestinal surgery and hernia and abdominal wall surgery].

    Chen, Shuang

    2015-11-25

    The aim of this article is to expound on the crossing and influence each other of gastrointestinal surgery and abdominal wall hernia surgery. Although these two departments are independent respectively, but due to the existence of association among anatomy, physiology and pathology, so they are also overlapping. First of all, the abdominal wall and digestive tract are interdependent, and the abdominal wall provides "protection" for gut. In case of large abdominal wall defect, intra-abdominal viscera, breathing, circulation system and spine will change accordingly. In addition, when intra-abdominal pressure increases due to various reasons, laparotomy is an effective way. But laparotomy is not an easy case, but a crisis. One of the most difficult problems is "enteroatmospheric fistulae". Therefore, to avoid serious complications after laparotomy, the concept of planned ventral hernia is proposed. When life safety is threatened by inter-abdominal hypertension, planned abdominal wall hernia is the style to save life. This is a kind of concept of innovation, and is the concrete practice of the theory of damage control surgery. For a planned abdominal wall hernia patient, it is better to wait and watch, and after making a comprehensive assessment, multidisciplinary collaboration mode should be applied to ensure the safety of surgery.

  4. Physiology of vitreous surgery.

    Stefánsson, Einar

    2009-02-01

    Vitreous surgery has various physiological and clinical consequences, both beneficial and harmful. Vitrectomy reduces the risk of retinal neovascularization, while increasing the risk of iris neovascularization, reduces macular edema and stimulates cataract formation. These clinical consequences may be understood with the help of classical laws of physics and physiology. The laws of Fick, Stokes-Einstein and Hagen-Poiseuille state that molecular transport by diffusion or convection is inversely related to the viscosity of the medium. When the vitreous gel is replaced with less viscous saline, the transport of all molecules, including oxygen and cytokines, is facilitated. Oxygen transport to ischemic retinal areas is improved, as is clearance of VEGF and other cytokines from these areas, thus reducing edema and neovascularization. At the same time, oxygen is transported faster down a concentration gradient from the anterior to the posterior segment, while VEGF moves in the opposite direction, making the anterior segment less oxygenated and with more VEGF, stimulating iris neovascularization. Silicone oil is the exception that proves the rule: it is more viscous than vitreous humour, re-establishes the transport barrier to oxygen and VEGF, and reduces the risk for iris neovascularization in the vitrectomized-lentectomized eye. Modern vitreous surgery involves a variety of treatment options in addition to vitrectomy itself, such as photocoagulation, anti-VEGF drugs, intravitreal steroids and release of vitreoretinal traction. A full understanding of these treatment modalities allows sensible combination of treatment options. Retinal photocoagulation has repeatedly been shown to improve retinal oxygenation, as does vitrectomy. Oxygen naturally reduces VEGF production and improves retinal hemodynamics. The VEGF-lowering effect of photocoagulation and vitrectomy can be augmented with anti-VEGF drugs and the permeability effect of VEGF reduced with corticosteroids

  5. [Catheter jejunostomy in elective abdominal surgery].

    Bodoky, A; Heberer, M; Iwatschenko, P; Harder, F

    1985-10-01

    Needle catheter jejunostomy is used to a varying extent today. Therefore, the need for nutritional support was evaluated following elective abdominal surgery and compared to experiences with postoperative enteral feeding. Oesophagectomy, total gastrectomy and the Whipple procedure were identified as good indications for catheter jejunostomy, whereas with other types of operation an individual decision is required.

  7. [Surgical criteria for reoperation in abdominal surgery].

    Bricot, R

    1975-07-01

    Analysis of the surgical criteria for reintervention in Abdominal Surgery led to the accentuation of a certain number of pictures of occlusion, general infectious syndromes, postoperative peritonitis, gastro-intestinal fistula and hemorrhagic syndrome. In all cases, the clinical examination can be misleading in particular in the case of peritonitis, and the history and non-surgical criteria must be strongly borne in mind. PMID:2036

  8. Chylous complications after abdominal aortic surgery.

    Haug, E S; Saether, O D; Odegaard, A; Johnsen, G; Myhre, H O

    1998-12-01

    Two patients developed chylous complications following abdominal aortic aneurysm repair. One patient had chylous ascitis and was successfully treated by a peritoneo-caval shunt. The other patient developed a lymph cyst, which gradually resorbed after puncture. Chylous complications following aortic surgery are rare. Patients in bad a general condition should be treated by initial paracentesis and total parenteral nutrition, supplemented by medium-chain triglyceride and low-fat diet. If no improvement is observed on this regimen, the next step should be implementation of a peritoneo-venous shunt, whereas direct ligation of the leak should be reserved for those who are not responding to this treatment.

    Full Text Available Introduction. Kidney anomalies present a challenge even for the most experienced vascular surgeon in the reconstruction of the aortoilliac segment. The most significant anomalies described in the surgery of the aortoilliac segment are a horse-shoe and ectopic kidney. Objective. The aim of this retrospective study was to analyze experience on 40 patients with renal anomalies, who underwent surgery of the aortoilliac segment and to determine attitudes on conventional surgical treatment. Methods. In the period from 1992 to 2009, at the Clinic for Vascular Surgery of the Clinical Centre of Belgrade we operated on 40 patients with renal anomalies and aortic disease (aneurysmatic and obstructive. The retrospective analysis involved standard epidemiological data of each patient (gender, age, risk factors for atherosclerosis, type of anomaly, type of aortic disease, presurgical parameter values of renal function, type of surgical approach (laparatomy or retroperitoneal approach, classification of the renal isthmus, reimplantation of renal arteries and perioperative morbidity and mortality. Results. Twenty patients were males In 30 (70% patients we diagnosed a horse-shoe kidney and in 10 (30% ectopic kidney. In the cases of ruptured aneurysm of the abdominal aorta the diagnosis was made by ultrasound findings. Pre-surgically, renal anomalies were confirmed in all patients, except in those with a ruptured aneurysm who underwent urgent surgery. In all patients we applied medial laparatomy, except in those with a thoracoabdominal aneurysm type IV, when the retroperitonal approach was necessary. On average the patients were under follow-up for 6.2 years (from 6 months to 17 years. Conclusion. Under our conditions, the so-called double clamp technique with the preservation of the kidney gave best results in the patients with renal anomalies and aortic disease.

  10. Anesthetic Considerations for Abdominal Wall Reconstructive Surgery

    Slabach, Rachel; Suyderhoud, Johan P.

    2012-01-01

    Anesthesia considerations for abdominal wall reconstruction (AWR) are numerous and depend upon the medical status of the patient and the projected procedure. Obesity, sleep apnea, hypertension, and cardiovascular disease are not uncommon in patients with abdominal wall defects; pulmonary functions and cardiac output can be affected by the surgical procedure. Patients with chronic obstructive pulmonary disease are also at a higher risk of coughing during the postoperative awakening process, wh...

  11. Postoperative cognitive dysfunction and neuroinflammation; Cardiac surgery and abdominal surgery are not the same.

    Hovens, Iris B; van Leeuwen, Barbara L; Mariani, Massimo A; Kraneveld, Aletta D; Schoemaker, Regien G

    2016-05-01

    Postoperative cognitive dysfunction (POCD) is a debilitating surgical complication, with cardiac surgery patients at particular risk. To gain insight in the mechanisms underlying the higher incidence of POCD after cardiac versus non-cardiac surgery, systemic and central inflammatory changes, alterations in intraneuronal pathways, and cognitive performance were studied after cardiac and abdominal surgery in rats. Male Wistar rats were subjected to ischemia reperfusion of the upper mesenteric artery (abdominal surgery) or the left coronary artery (cardiac surgery). Control rats remained naïve, received anesthesia only, or received thoracic sham surgery. Rats were subjected to affective and cognitive behavioral tests in postoperative week 2. Plasma concentrations of inflammatory factors, and markers for neuroinflammation (NGAL and microglial activity) and the BDNF pathway (BDNF, p38MAPK and DCX) were determined. Spatial memory was impaired after both abdominal and cardiac surgery, but only cardiac surgery impaired spatial learning and object recognition. While all surgical procedures elicited a pronounced acute systemic inflammatory response, NGAL and TNFα levels were particularly increased after abdominal surgery. Conversely, NGAL in plasma and the paraventricular nucleus of the hypothalamus and microglial activity in hippocampus and prefrontal cortex on postoperative day 14 were increased after cardiac, but not abdominal surgery. Both surgery types induced hippocampal alterations in BDNF signaling. These results suggest that POCD after cardiac surgery, compared to non-cardiac surgery, affects different cognitive domains and hence may be more extended rather than more severe. Moreover, while abdominal surgery effects seem limited to hippocampal brain regions, cardiac surgery seems associated with more wide spread alterations in the brain. PMID:26867718

  13. Abdominal surgery activates nesfatin-1 immunoreactive brain nuclei in rats.

    Stengel, Andreas; Goebel, Miriam; Wang, Lixin; Taché, Yvette

    2010-02-01

    Abdominal surgery-induced postoperative gastric ileus is well established to induce Fos expression in specific brain nuclei in rats within 2-h after surgery. However, the phenotype of activated neurons has not been thoroughly characterized. Nesfatin-1 was recently discovered in the rat hypothalamus as a new anorexigenic peptide that also inhibits gastric emptying and is widely distributed in rat brain autonomic nuclei suggesting an involvement in stress responses. Therefore, we investigated whether abdominal surgery activates nesfatin-1-immunoreactive (ir) neurons in the rat brain. Two hours after abdominal surgery with cecal palpation under short isoflurane anesthesia or anesthesia alone, rats were transcardially perfused and brains processed for double immunohistochemical labeling of Fos and nesfatin-1. Abdominal surgery, compared to anesthesia alone, induced Fos expression in neurons of the supraoptic nucleus (SON), paraventricular nucleus (PVN), locus coeruleus (LC), Edinger-Westphal nucleus (EW), rostral raphe pallidus (rRPa), nucleus of the solitary tract (NTS) and ventrolateral medulla (VLM). Double Fos/nesfatin-1 labeling showed that of the activated cells, 99% were nesfatin-1-immunoreactive in the SON, 91% in the LC, 82% in the rRPa, 74% in the EW and VLM, 71% in the anterior parvicellular PVN, 47% in the lateral magnocellular PVN, 41% in the medial magnocellular PVN, 14% in the NTS and 9% in the medial parvicellular PVN. These data established nesfatin-1 immunoreactive neurons in specific nuclei of the hypothalamus and brainstem as part of the neuronal response to abdominal surgery and suggest a possible implication of nesfatin-1 in the alterations of food intake and gastric transit associated with such a stressor.

    Nils Bjerregaard

    2012-01-01

    Full Text Available Purpose. Transversus abdominis plane (TAP blocks have been shown to reduce pain and opioid requirements after abdominal surgery. The aim of the present case series was to demonstrate the use of TAP catheter injections of bupivacaine after major abdominal surgery. Methods. Fifteen patients scheduled for open colonic resection surgery were included. After induction of anesthesia, bilateral TAP catheters were placed, and all patients received a bolus dose of 20 mL bupivacaine 2.5 mg/mL with epinephrine 5 μg/mL through each catheter. Additional bolus doses were injected bilaterally 12, 24, and 36 hrs after the first injections. Supplemental pain treatment consisted of paracetamol, ibuprofen, and gabapentin. Intravenous morphine was used as rescue analgesic. Postoperative pain was rated on a numeric rating scale (NRS, 0–10 at regular predefined intervals after surgery, and consumption of intravenous morphine was recorded. Results. The TAP catheters were placed without any technical difficulties. NRS scores were ≤3 at rest and ≤5 during cough at 4, 8, 12, 18, 24, and 36 hrs after surgery. Cumulative consumption of intravenous morphine was 28 (23–48 mg (median, IQR within the first 48 postoperative hours. Conclusion. TAP catheter bolus injections can be used to prolong analgesia after major abdominal surgery.

    2008-01-01

    Background. It is believed that the severely disturbed night-time sleep architecture after surgery is associated with increased cardiovascular morbidity with rebound of rapid eye movement (REM). The daytime sleep pattern of patients after major general surgery has not been investigated before. We...... decided to study the circadian distribution of sleep phases before and after surgery. Methods. Eleven patients undergoing elective major abdominal surgery were included in the study. Continuous ambulatory polysomnographic monitoring was made 24 h before surgery and 36 h after surgery, thus including two...... nights after operation. Sleep was scored independently by two blinded observers and the recordings were reported as awake, light sleep (LS, stages I and II), slow wave sleep (SWS, stages III and IV), and REM sleep. Results. There was significantly increased REM sleep (P=0.046), LS (P=0.020), and reduced...

  17. Intra-abdominal pressure and abdominal compartment syndrome in acute general surgery.

    Sugrue, Michael

    2012-01-31

    BACKGROUND: Intra-abdominal pressure (IAP) is a harbinger of intra-abdominal mischief, and its measurement is cheap, simple to perform, and reproducible. Intra-abdominal hypertension (IAH), especially grades 3 and 4 (IAP > 18 mmHg), occurs in over a third of patients and is associated with an increase in intra-abdominal sepsis, bleeding, renal failure, and death. PATIENTS AND METHODS: Increased IAP reading may provide an objective bedside stimulus for surgeons to expedite diagnostic and therapeutic work-up of critically ill patients. One of the greatest challenges surgeons and intensivists face worldwide is lack of recognition of the known association between IAH, ACS, and intra-abdominal sepsis. This lack of awareness of IAH and its progression to ACS may delay timely intervention and contribute to excessive patient resuscitation. CONCLUSIONS: All patients entering the intensive care unit (ICU) after emergency general surgery or massive fluid resuscitation should have an IAP measurement performed every 6 h. Each ICU should have guidelines relating to techniques of IAP measurement and an algorithm for management of IAH.

  18. Laparoscopic cholecystectomy causes less sleep disturbance than open abdominal surgery

    BACKGROUND: The aim of this study was to examine subjective sleep quality before and after laparoscopic vs open abdominal surgery. METHODS: Twelve patients undergoing laparoscopic cholecystectomy and 15 patients undergoing laparotomy were evaluated with the aid of a sleep questionnaire from 4 days...... before until 4 weeks after surgery. RESULTS: Following laparoscopic surgery, total sleep time increased during the 1st week after the operation compared with preoperative values (p = 0.02), whereas sleep duration during weeks 2, 3, and 4 did not differ from the times reported preoperatively. Following...... laparotomy, sleep duration increased during the 1st, 3rd, and 4th weeks after the operation compared with preoperative values (p < 0.05). All patients experienced postoperative circadian sleep disturbance, with significantly more sleep during the daytime compared with preoperative values; the disturbance was...

  19. [Influences of chest deformation by upper abdominal retractor on respiratory system impedance during abdominal surgery].

    Oka, T; Ozawa, Y; Sato, J

    1999-02-01

    The present study was carried out to clarify the effects of chest deformation by upper abdominal retractor on respiratory system impedance during abdominal surgery. We measured the impedances of respiratory system (RS), lung, and chest wall (CW) in nine anesthetized paralyzed subjects employing a pseudorandom noise forced volume oscillation technique. These measurements were performed before and after the lifting chest wall by upper abdominal retractor. The effects of chest deformation was significant on the impedances of RS, lung, while no discernible effect was found in CW impedance. Lifting chest wall decreased RS resistance which was totally accounted for by the decrease in lung resistance, whereas the lifting did not affect reactance in either RS or lung. The mathematical modeling showed the significant lifting effect on the resistance of the parenchyma. In conclusion, change in RS mechanics produced by chest deformation by upper abdominal retractor is dominated in lung but not in CW. Among the lung mechanical components, parenchyma is the primary site of the lifting effect. PMID:10087819

    2012-05-01

    Full Text Available Abstract Objective This study aimed to investigate clinical features of abdominal emergency surgery in elderly patients, and to determine factors predicting mortality in these patients. Methods The study population included 94 patients aged 80 years or older who underwent emergency surgery for acute abdominal diseases between 2000 and 2010. Thirty-six patients (38.3% were male and fifty-eight patients (61.7% were female (mean age, 85.6 years. Main outcome measures included background of the patient’s physical condition (concomitant medical disease, and performance status, cause of disease, morbidity and mortality, and disease scoring system (APACHE II, and POSSUM. Prognostic factors affecting mortality of the patient were also evaluated by univariate analysis using Fisher’s exact test and Mann–Whitney U–test, and by multivariate analysis using multiple logistic regression analysis. Results Of the 94 patients, 71 (75.5% had a co-existing medical disease; most patients had hypertension (46.8%. The most frequent surgical indications were acute cholecystitis in 23 patients (24.5%, followed by intestinal obstruction in 18 patients (19.1%. Forty-one patients (43.6% had complications during hospital stay; the most frequent were surgical site infection (SSI in 21 patients (22.3% and pneumonia in 12 patients (12.8%. Fifteen patients died (overall mortality, 16% within 1 month after operation. The most common causes of death were sepsis related to pan-peritonitis in 5 patients (5.3%, and pneumonia in 4 patients (4.3%. Multiple logistic regression analysis showed that time from onset of symptoms to hospital admission and the POSSUM scoring system could be prognostic factors for mortality. Conclusions Mortality in elderly patients who underwent emergency surgery for acute abdominal disease can be predicted using the disease scoring system (POSSUM and on the basis of delay in hospital admission.

  2. Unexpectedly ease surgery for a worrisome abdominal mass: Pedunculated GISTs☆

    Baskiran, Adil; Otan, Emrah; Aydin, Cemalettin; Kayaalp, Cuneyt

    2013-01-01

    INTRODUCTION Discovery of abdominal masses often poses significant diagnostic difficulties. GISTs are mesenchymal masses, with specific histological features. Dimensions may vary from millimeters to giant tumours. We would like to present our case, which had an unexpectedly easy operative course which was easily handled with a simple surgical excision with a short operative duration. PRESENTATION OF CASE A 38 years old female patient was diagnosed to have an abdominal heterogen mass of 15 cm × 12 cm × 10 cm in dimension. Abdominal computed tomography revealed the solid mass between the stomach and pancreas corpus and tail, possibly orginating from the pancreas. With the preoperative diagnosis of locally invasive distal pancreas cancer the patient underwent laparotomy, following the dissection, the mass was observed to be originating from the posterior gastric Wall, extending exophytically with a peduncle of 5 cm in width, without any visual evidence for peritoneal invasion and metastasis. The tumour and the peduncle was resected with stapler device. Total operation time was 30 min. Postoperative course was uneventful. Pathologic diagnosis was gastrointestinal stromal tumour (GIST). DISCUSSION Pedunculated large GISTs are not frequent and they can enlarge as 15 cm in diameter and compress the neighbouring organs. When they were huge, it is difficult to differentiate the origin of the masses. GISTs should be considered in differential diagnosis of giant abdominal masses. CONCLUSION When GISTs are huge and pedunculated, it can be difficult to differentiate the origin of the masses. This case report presents unexpectedly ease surgery for a worrysome abdominal mass.

    2015-01-01

    Full Text Available Candida endocarditis is an emerging infectious disease, usually involving patients with intravascular prosthetic devices, and associated with substantial morbidity and mortality. A 28-year-old primigravida at 32 weeks of gestation was admitted with low-grade fever and lower abdominal pain for 2 weeks. She had undergone open appendicectomy 2 months before admission. Echocardiogram showed a pedunculated 24 mm × 21 mm mass attached to the undersurface of anterior mitral leaflet near the tip and moderate mitral regurgitation. Repeated blood cultures showed growth of nonalbicans candida. She was immediately started on liposomal amphotericin and was taken up for surgery, but despite all efforts she succumbed to her illness.

    1990-01-01

    Adrenaline-induced changes in heart rate, blood pressure, plasma adrenaline and noradrenaline, cortisol, glucagon, insulin, cAMP, glucose lactate, glycerol and beta-hydroxybutyrate were studied preoperatively and 4 and 24 h after skin incision in 8 patients undergoing elective cholecystectomy. Late...... postoperative responses of blood glucose, plasma cAMP, lactate and glycerol to adrenaline infusion were reduced, whereas other responses were unaffected. Blood glucose appearance and disappearance rate as assessed by [3H]3-glucose infusion was unchanged pre- and postoperatively. The increase in glucose...... appearance rate following adrenaline was similar pre- and postoperatively. These findings suggest that several beta-receptor-mediated responses to adrenaline are reduced after abdominal surgery....

  6. Abdominal surgery process modeling framework for simulation using spreadsheets.

    2015-08-01

    We provide a continuation of the existing Activity Table Modeling methodology with a modular spreadsheets simulation. The simulation model developed is comprised of 28 modeling elements for the abdominal surgery cycle process. The simulation of a two-week patient flow in an abdominal clinic with 75 beds demonstrates the applicability of the methodology. The simulation does not include macros, thus programming experience is not essential for replication or upgrading the model. Unlike the existing methods, the proposed solution employs a modular approach for modeling the activities that ensures better readability, the possibility of easily upgrading the model with other activities, and its easy extension and connectives with other similar models. We propose a first-in-first-served approach for simulation of servicing multiple patients. The uncertain time duration of the activities is modeled using the function "rand()". The patients movements from one activity to the next one is tracked with nested "if()" functions, thus allowing easy re-creation of the process without the need of complex programming. PMID:26004999

    2013-01-01

    Abstract Damage control laparotomy was first described by Dr. Harlan Stone in 1983 when he suggested that patients with severe trauma should have their primary procedures abbreviated when coagulopathy was encountered. He recommended temporizing patients with abdominal packing and temporary closure to allow restoration of normal physiology prior to returning to the operating room for definitive repair. The term damage control in the trauma setting was coined by Rotondo et al., in 1993. ...

    2016-05-01

    Damage control surgery (DCS) was developed to manage exsanguinating trauma patients, but is increasingly applied to the management of peritoneal sepsis and abdominal catastrophes. Few manuscripts compare the outcomes of these surgeries on disparate patient populations. A multi-institutional three group propensity score matched case cohort study comparing penetrating trauma (PT-DCS), blunt trauma (BT-DCS), and intraperitoneal sepsis (IPS-DCS) was performed comparing patients treated with DSC between 2008 and 2013. Propensity scoring was performed using demographic and presenting physiologic data. Four hundred and twelve patients were treated with DCS across two institutions. Propensity matching for age, gender, and initial Acute Physiology and Chronic Health Evaluation II score 80 identified 80 patients per group for comparison. Rate of primary fascial closure was lowest in the IPS-DCS group, and highest in the penetrating trauma DCS group. Intra-abdominal complication rates were highest in the IPS-DCS group. IPS-DCS had increased time to definitive closure compared with the other two groups (RR 1.8; 1.3-2.2; P eight days were more than twice the risk of death at 90 days across all groups. (RR 2.15; 1.2-3.5; P trauma and emergency general surgery are quite different. Despite this difference, prompt abdominal closure at the earliest possible opportunity afforded the best outcome in patients managed via DCS. PMID:27215724

    2006-01-01

    AIM: To design a hand-assisted laparoscopic approach in an attempt to provide an option for laparoscopic resection of abdominal large viscera.METHODS: A 5-6 cm incision (for HandPort) and 2 trocars were employed. The main vessel of the target organ was taken as a "core", and all tissues around the core were taken as peripheral structures. The peripheral structures were dissected first, and the core vessels were treated last. Twenty-six patients underwent laparoscopic deroofing of the hepatic huge cysts, resection of the segments lying at the outer edge of the liver (segments 2 to 6), splenectomy, hemicolectomy, ileocecectomy and subtotal gastrectomy with HandPort device, harmonic scalpel, or Ligasure.RESULTS: The duration of the procedure was within 2 hours. Blood loss amounted to 8-120 mL. The conversion rate was 3.8% (1/26). All patients had uneventful postoperative courses with less pain, earlier oral intake,and faster recovery, compared with conventional surgery.CONCLUSION: This method combines the advantages of both open and laparoscopic techniques, achieving better hemostasis effect, shortening the operative time,and is beneficial to the patients.

    The development of abdominal surgery represents an alternative therapy for the morbidly obese; however, patients undergoing this surgical procedure often experience postoperative pulmonary complications. The use of alveolar recruitment maneuvers and/or perioperative ventilatory strategies is a possible alternative to reduce these complications, focusing on the reduction of postoperative pulmonary complications. In this review, the benefits of perioperative ventilatory strategies and the implementation of alveolar recruitment maneuvers in obese patients undergoing abdominal surgery are described.

    Abbreviated laparotomy and planned reoperation(s) is a new concept in severely injured patients with multivisceral failure by hemorrhagic shock, coagulopathy and hypothermia. The aim of an abbreviated laparotomy is to control hemorrhage, prevent digestive contamination and close the abdominal wall without tension. After a delay for reanimation during 24 to 96 hours, discovery of unknown lesions and anatomic reconstruction will be possible through planned reoperation in better conditions. Emergency reoperation for hemorrhage and abdominal hyperpression severely worsens prognosis. PMID:10921187

    The clinical presentations of diaphragm dysfunctions vary according to etiologies and unilateral or bilateral diseases. Elevation of the hemidiaphragm from peripheral origins, the most frequent situation, requires a surgical treatment only in case of major functional impact. Complete morphological and functional analyses of the neuromuscular chain and respiratory tests allow the best selection of patients to be operated. The surgical procedure may be proposed only when the diaphragm dysfunction is permanent and irreversible. Diaphragm plication for eventration through a short lateral thoracotomy, or sometimes by videothoracoscopy, is the only procedure for retensioning the hemidiaphragm. This leads to a decompression of intrathoracic organs and a repositioning of abdominal organs without effect on the hemidiaphragm active contraction. Morbidity and mortality rates after diaphragm plication are very low, more due to the patient's general condition than to surgery itself. Functional improvements after retensioning for most patients with excellent long-term results validate this procedure for symptomatic patients. In case of bilateral diseases, very few bilateral diaphragm plications have been reported. Some patients with diaphragm paralyses from central origins become permanently dependent on mechanical ventilation whereas their lungs, muscles and nerves are intact. In patients selected by rigorous neuromuscular tests, a phrenic pacing may be proposed to wean them from respirator. Two main indications have been validated: high-level tetraplegia above C3 and congenital alveolar hypoventilation from central origin. After progressive reconditioning of the diaphragm muscles following phrenic pacing at thoracic level, more than 90% of patients can be weaned from respirator within a few weeks. This weaning improves the quality of life with more physiological breathing, restored olfaction, better sleep and better speech. The positive impact of diaphragm stimulation has also

  7. Past, Present, and Future of Minimally Invasive Abdominal Surgery.

    Antoniou, Stavros A; Antoniou, George A; Antoniou, Athanasios I; Granderath, Frank-Alexander

    2015-01-01

    Laparoscopic surgery has generated a revolution in operative medicine during the past few decades. Although strongly criticized during its early years, minimization of surgical trauma and the benefits of minimization to the patient have been brought to our attention through the efforts and vision of a few pioneers in the recent history of medicine. The German gynecologist Kurt Semm (1927-2003) transformed the use of laparoscopy for diagnostic purposes into a modern therapeutic surgical concept, having performed the first laparoscopic appendectomy, inspiring Erich Mühe and many other surgeons around the world to perform a wide spectrum of procedures by minimally invasive means. Laparoscopic cholecystectomy soon became the gold standard, and various laparoscopic procedures are now preferred over open approaches, in the light of emerging evidence that demonstrates less operative stress, reduced pain, and shorter convalescence. Natural orifice transluminal endoscopic surgery (NOTES) and single-incision laparoscopic surgery (SILS) may be considered further steps toward minimization of surgical trauma, although these methods have not yet been standardized. Laparoscopic surgery with the use of a robotic platform constitutes a promising field of investigation. New technologies are to be considered under the prism of the history of surgery; they seem to be a step toward further minimization of surgical trauma, but not definite therapeutic modalities. Patient safety and medical ethics must be the cornerstone of future investigation and implementation of new techniques. PMID:26508823

    2015-01-01

    Background: General anesthesia usually requires mechanical ventilation, which is traditionally accomplished with constant tidal volumes in volume- or pressure-controlled modes. Experimental studies suggest that the use of variable tidal volumes (variable ventilation) recruits lung tissue, improves pulmonary function and reduces systemic inflammatory response. However, it is currently not known whether patients undergoing open abdominal surgery might benefit from intraoperative variable ventil...

    2009-01-01

    Objective To evaluate the effects of supplementation of glutamine (GLN) on maintaining glutathione (GSH) level, immune system function, liver function, and clinical outcome of patients receiving abdominal operation. Methods Forty patients undergoing elective abdominal surgical treatment were randomly divided into 2 groups: study group (n = 20) and control group (n = 20). All patients received total parenteral nutrition (TPN) for up to 7 days during perioperative period. The study group received TPN supplemented with GLN dipeptide while the control group received TPN without GLN dipeptide. Patients in both groups received equivalent nitrogen and caloric intake. Blood sample was taken on preoperative day, and the 1st, 3rd, 6th postoperative day to measure GSH level, immune indexes, and liver function indexes. Results The decrease of GSH level in plasma and red blood cell (RBC) in study group was less than that in control group during postoperative period. Ratio of GSH/glutathione disulfide (GSSG) in plasma in study group was higher than that in control group on the 3rd postoperative day (52.53 ± 11.46 vs. 31.43 ± 7.27, P = 0.001). Albumin level in study group was higher than that in control group on the 3rd postoperative day (37.7 ± 3.8 g/L vs. 33.8 ± 4.2 g/L, P = 0.02). There was no significant difference in the levels of immunoglobin (IgG, IgM, IgA) or T lymphocyte subgroup (CD4, CD8, CD4/CD8) in both groups during postoperative period. There was one case with infectious complication in control group, while none in study group. A trend of shortened hospital stay was observed in study group compared with control group (22.3 ± 2.1 d vs. 24.9 ± 1.7 d, P = 0.32). Conclusions Supplementation of GLN-enriched TPN has beneficial effects on maintaining GSH levels in plasma and RBC, sustaining GSH/GSSG ratio and albumin level, and keeping antioxidant abilities during postoperative period in patients with abdominal operation, with the trends of decreasing incidence of

  14. Indications for needle catheter jejunostomy in elective abdominal surgery.

    Heberer, M; Bodoky, A; Iwatschenko, P; Harder, F

    1987-06-01

    Needle catheter jejunostomy for postoperative nutritional support is now employed worldwide. However, there is a large discrepancy regarding indications for this technique which this study attempts to rectify. The need for nutritional support after elective abdominal procedures in 464 patients was analyzed and compared with the experience with needle catheter jejunostomy in 42 patients. The results show that needle catheter jejunostomy is indicated after extensive operations of the upper gastrointestinal tract, for example, esophagectomy, total gastrectomy, and the Whipple procedure. With minor upper gastrointestinal operations, or procedures of the lower gastrointestinal tract, needle catheter jejunostomy should be performed only in patients with poor nutritional status or in the presence of postoperative chemotherapy or radiotherapy. In an unclear situation, liberal insertion of the needle catheter jejunostomy and a postponed decision on enteral feeding is recommended, as there is no significant catheter-related morbidity.

  16. Diagnostic application of labelled leukocytes in gastroenterology and abdominal surgery

    A total of 18 patients suspected of inflammatory process or abcessus in the abdominal cavity have been studied by scintiscanning with autologous leukocytes labelled with 111In-oxine (10-12 MBq) or 99mTc-HMPAO (300 MBq). Evaluation of the process activity is done on the ground activity index adopted which is received after the computer processing of the results. Three levels of process activity are determined: 1) when the leukocyte accumulation (LA) corresponds to that in the bone marrow; 2) when the LA corresponds to that in the liver; 3) when the LA corresponds to that in the spleen. The recorded sensitivity, specificity and accuracy of the method amount to 87.5%, 100% and 92.9% respectively. The method allows localization of the inflammatory process and indicates the degree of affecting the intestines. 2 figs., 6 refs

  20. Perioperative Nutrition in Abdominal Surgery: Recommendations and Reality

    Yannick Cerantola

    2011-01-01

    Full Text Available Introduction. Preoperative malnutrition is a major risk factor for increased postoperative morbidity and mortality. Definition and diagnosis of malnutrition and its treatment is still subject for controversy. Furthermore, practical implementation of nutrition-related guidelines is unknown. Methods. A review of the available literature and of current guidelines on perioperative nutrition was conducted. We focused on nutritional screening and perioperative nutrition in patients undergoing digestive surgery, and we assessed translation of recent guidelines in clinical practice. Results and Conclusions. Malnutrition is a well-recognized risk factor for poor postoperative outcome. The prevalence of malnutrition depends largely on its definition; about 40% of patients undergoing major surgery fulfil current diagnostic criteria of being at nutritional risk. The Nutritional Risk Score is a pragmatic and validated tool to identify patients who should benefit from nutritional support. Adequate nutritional intervention entails reduced (infectious complications, hospital stay, and costs. Preoperative oral supplementation of a minimum of five days is preferable; depending on the patient and the type of surgery, immune-enhancing formulas are recommended. However, surgeons' compliance with evidence-based guidelines remains poor and efforts are necessary to implement routine nutritional screening and nutritional support.

  1. Postoperative nutrition practices in abdominal surgery patients in a tertiary referral hospital Intensive Care Unit: A prospective analysis

    Tejaswini Arunachala Murthy

    2016-01-01

    Full Text Available Background: Benefit of early enteral feeds in surgical patients admitted to Intensive Care Units (ICUs has been emphasized by several studies. Apprehensions about anastomotic leaks in gastrointestinal surgical patients prevent initiation of early enteral nutrition (EN. The impact of these practices on outcome in Indian scenario is less studied. Aims: This study compares the impact of early EN (within 48 h after surgery with late EN (48 h postsurgery on outcomes in abdominal surgical ICU patients. Settings and Design: Postabdominal surgery patients admitted to a tertiary referral hospital ICU over a 2-year period were analyzed. Methods: Only patients directly admitted to ICU after abdominal surgery were included in this study. ICU stay>3 days was considered as prolonged; with average ICU length of stay (LOS for this ICU being 3 days. The primary outcome was in-patient mortality. ICU LOS, hospital LOS, infection rates, and ventilator days were secondary outcome measures. Acute Physiology and Chronic Health Evaluation II scores were calculated. SPSS and Microsoft Excel were used for analysis. Results: Of 91 ICU patients included, 58 received early EN and 33 late EN. Hospital LOS and infection rates were less in early EN group. Use of parenteral nutrition (odds ratio [OR] 5.25, 95% confidence interval (CI; P = 0.003 and number of nil-per-oral days (OR 8.25, 95% CI; P ≤ 0.001 were other predictors of prolonged LOS. Conclusions: Early EN in postabdominal surgery ICU patients was associated with reduced hospital LOS and infection rates. ICU LOS, duration of mechanical ventilation and mortality rates did not vary.

  3. Does chewing gum improve recovery after an abdominal surgery?--First update.

    Rada, Gabriel; Viñuela, José

    2015-01-01

    This Living FRISBEE (Living FRIendly Summary of the Body of Evidence using Epistemonikos) is an update of the summary published in November 2014, based on four new systematic reviews published since then. Postoperative ileus is common condition that delays recovery after an abdominal surgery. Early use of sham feeding with chewing gum stimulates peristalsis and would allow an earlier nutrition. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified 18 systematic reviews including 81 randomized trials. We combined the evidence using meta-analysis and generated a summary of findings following the GRADE approach. We concluded that chewing gum probably reduces the length of hospital stay after an abdominal surgery. PMID:25627680

    Background Chylous ascites is the pathologic leakage of triglycerides-rich lymphatic fluid into the peritoneal cavity. Chylous ascites is a rare complication in abdominal surgery. This study aimed to find a relatively better method for nutrition support in the treatment of chylous ascites after abdominal surgery. Methods This study was a retrospective study. This study retrospectively reviewed patients who underwent abdominal surgery and developed chylous ascites, from the year 2010 to 2014, at the West China Hospital of Sichuan University and the Affiliated Hospital of Zunyi Medical College. Fifty-eight patients who developed chylous ascites after abdominal surgery were included in the study. The clinical effect of somatostatin was evaluated. The differences in the curative efficacy among a daily diet, a low-fat diet supplemented with medium-chain triglyceride (MCT), and total parenteral nutrition (TPN) were also analyzed in this study. Results Complete clinical success was reached earlier in patients treated with somatostatin (P<0.001). The tube removal time, the time to resumption of an oral diet, and the length of hospital stay after chylous leakage were significantly different between patients treated with and without somatostatin. The curative efficacies of the enteral nutrition (EN) + MCT plan and the TPN plan were quite similar, with no significant difference, however, were significantly different from the MCT regime, which was the worst. However, using the EN + MCT plan was more cost-effective (P=0.038). Conclusion In treating chylous ascites, EN + MCT instead of TPN was the best nutrition support. Moreover, somatostatin or its analog octreotide should be used immediately. The treatment with somatostatin in combination with EN + MCT is recommended in the conservative treatment of postoperative chylous ascites. PMID:27143902

    2005-01-01

    Objective To evaluate the effect of intraoperative combined forced-air warming and fluid warming system on patient's core temperature, blood loss, transfusion demand, extubation time, and incidence of postoperative shivering.Methods Forty patients with American Society of Anesthesiologists physical status Ⅰ and Ⅱ, aged 18-70 years, scheduled for elective abdominal surgery were randomly assigned to receive intraoperative warming from a forced-air blanket and fluid warming system or conventional cotton blanket, 20 in each group. The core temperature was recorded every 20 minutes during the operation, as well as the blood loss, blood transfusion, extubation time, and incidence of postoperative shivering.Results The core temperature at the end of the surgery in the wanning group was significantly different from that in the control group (36.4±0.4C vs. 35.3±0.5°C, P<0.001). Application of intraoperative warming significantly shortened the time between the end of the surgery and extubation (P<0.01). Postoperative shivering occurred in 30% of the patients in the control group compared to no patient in the warming group (P <0.01).Conclusion Active warming with air-forced blanket and fluid warming system provides sufficient heat to prevent hypothermia during abdominal surgery.

    Malavasi, Lais M; Greene, Stephen A; Gay, John M; Grubb, Tammy L

    2016-01-01

    Lidocaine is commonly used in ruminants but has an anecdotal history of being toxic to goats. To evaluate lidocaine's effects on selected cardiopulmonary parameters. Isoflurane-anesthetized adult goats (n = 24) undergoing abdominal surgery received a loading dose of lidocaine (2.5 mg/kg) over 20 min followed by constant-rate infusion of lidocaine (100 μg/kg/min); control animals received saline instead of lidocaine. Data collected at predetermined time points during the 60-min surgery included heart rate, mean arterial blood pressure, pO2, and pCO2. According to Welch 2-sample t tests, cardiopulmonary variables did not differ between groups. For example, after administration of the loading dose, goats in the lidocaine group had a mean heart rate of 88 ± 28 bpm, mean arterial blood pressure of 70 ± 19 mm Hg, pCO2 of 65 ± 13 mm Hg, and pO2 of 212 ± 99 mm Hg; in the saline group, these values were 90 ± 16 bpm, 76 ± 12 mm Hg, 61 ± 9 mm Hg, and 209 ± 83 mm Hg, respectively. One goat in the saline group required an additional dose of butorphanol. Overall our findings indicate that, at the dose provided, intravenous lidocaine did not cause adverse cardiopulmonary effects in adult goats undergoing abdominal surgery. Adding lidocaine infusion during general anesthesia is an option for enhancing transoperative analgesia in goats. PMID:27423150

    AIM: To assess the clinical and economical validity of glutamine dipeptide supplemented to parenteral nutrition(PN) in patients undergoing abdominal surgery.METHODS: A meta-analysis of all the relevant randomized controlled trials (RCTs) was performed. The trials compared the standard PN and PN supplemented with glutamine dipeptide in abdominal surgery. RCTs were identified from the following electronic databases:the Cochrane Library, MEDLINE, EMBASE and ISI web of knowledge (SCI). The search was undertaken in April 2006. Literature references were checked by computer or hand at the same time. Clinical trials were extracted and evaluated by two reviewers independently. Statistical analysis was performed by RevMan4.2 software from Cochrane Collaboration. A P value of <0.05 was considered statistically significant.RESULTS: Nine RCTs involving 373 patients were included. The combined results showed that glutamine dipeptide has a positive effect in improving postoperative cumulative nitrogen balance (weighted mean difference (WMD = 8.35, 95% CI [2.98, 13.71], P = 0.002),decreasing postoperative infectious morbidity (OR = 0.24,95% CI [0.06, 0.93], P = 0.04), shortening the length of hospital stay (WMD= -3.55, 95% CI [-5.26, -1.84], P<0.00001). No serious adverse effects were found.CONCLUSION: Postoperative PN supplemented with glutamine dipeptide is effective and safe to decrease the infectious rate, reduce the length of hospital stay and improve nitrogen balance in patients undergoing abdominal surgery. Further high quality trials in children and severe patients are required, and mortality and hospital cost should be considered in future RCTs with sufficient size and rigorous design.

    2009-07-01

    Full Text Available Abstract Background Intravenous (IV fluid administration is an essential part of postoperative care. Some studies suggest that a restricted post-operative fluid regime reduces complications and postoperative hospital stay after surgery. We investigated the effects of postoperative fluid restriction in surgical patients undergoing major abdominal surgery. Methods In a blinded randomized trial, 62 patients (ASA I-III undergoing elective major abdominal surgical procedures in a university hospital were allocated either to a restricted (1.5 L/24 h or a standard postoperative IV fluid regime (2.5 L/24 h. Primary endpoint was length of postoperative hospital stay (PHS. Secondary endpoints included postoperative complications and time to restore gastric functions. Results After a 1-year inclusion period, an unplanned interim analysis was made because of many protocol violations due to patient deterioration. In the group with the restricted regime we found a significantly increased PHS (12.3 vs. 8.3 days; p = 0.049 and significantly more major complications: 12 in 30 (40% vs. 5 in 32 (16% patients (Absolute Risk Increase: 0.24 [95%CI: 0.03 to 0.46], i.e. a number needed to harm of 4 [95%CI: 2–33]. Therefore, the trial was stopped prematurely. Intention to treat analysis showed no differences in time to restore gastric functions between the groups. Conclusion Restricted postoperative IV fluid management, as performed in this trial, in patients undergoing major abdominal surgery appears harmful as it is accompanied by an increased risk of major postoperative complications and a prolonged postoperative hospital stay.

  15. Seizure After Abdominal Surgery in an Infant Receiving a Standard-Dose Postoperative Epidural Bupivacaine Infusion.

    Shapiro, Peter; Schroeck, Hedwig

    2016-04-15

    We present the case of an otherwise healthy 12-month-old girl undergoing repair of a giant omphalocele, who experienced a postoperative seizure attributed to accumulation of bupivacaine from an epidural infusion. Whereas a standard dose was used, this patient experienced temporary liver dysfunction postoperatively, presumably from elevated intra-abdominal pressures, predisposing her to toxicity after a prolonged infusion. This case illustrates how the type of surgery can influence the margin of safety of routinely used neuraxial local anesthetic doses in infants and young children. PMID:26825992

    Tonguç U. Yilmaz

    2014-10-01

    Full Text Available Objectives: Resistin, a hormone secreted from adipocytes and considered to be a likely cause of insulin resistance, has recently been accepted as a proinflammatory cytokine. This study aimed to determine the correlation between resistin levels in patients with intra-abdominal sepsis and mortality. Methods: Of 45 patients with intraabdominal sepsis, a total of 35 adult patients were included in the study. This study was undertaken from December 2011 to December 2012 and included patients who had no history of diabetes mellitus and who were admitted to the general surgery intensive care units of Gazi University and Bülent Ecevit University School of Medicine, Turkey. Evaluations were performed on 12 patients with sepsis, 10 patients with severe sepsis, 13 patients with septic shock and 15 healthy controls. The patients’ plasma resistin, interleukin-6 (IL-6, tumour necrosis factor alpha (TNF-α, interleukin-1 beta (IL-1β, procalcitonin, lactate and glucose levels and Acute Physiology and Chronic Health Evaluation (APACHE II scores were studied daily for the first five days after admission. A correlation analysis of serum resistin levels with cytokine levels and APACHE II scores was performed. Results: Serum resistin levels in patients with sepsis were significantly higher than in the healthy controls (P <0.001. A significant correlation was found between serum resistin levels and APACHE II scores, serum IL-6, IL-1β, TNF-α, procalcitonin, lactate and glucose levels. Furthermore, a significant correlation was found between serum resistin levels and all-cause mortality (P = 0.02. Conclusion: The levels of resistin were significantly positively correlated with the severity of disease and were a possible mediator of a prolonged inflammatory state in patients with intra-abdominal sepsis.

  20. Effect of intermediate care on mortality following emergency abdominal surgery. The InCare trial: study protocol, rationale and feasibility of a randomised multicentre trial

    Vester-Andersen Morten

    2013-02-01

    Full Text Available Abstract Background Emergency abdominal surgery carries a 15% to 20% short-term mortality rate. Postoperative medical complications are strongly associated with increased mortality. Recent research suggests that timely recognition and effective management of complications may reduce mortality. The aim of the present trial is to evaluate the effect of postoperative intermediate care following emergency major abdominal surgery in high-risk patients. Methods and design The InCare trial is a randomised, parallel-group, non-blinded clinical trial with 1:1 allocation. Patients undergoing emergency laparotomy or laparoscopic surgery with a perioperative Acute Physiology and Chronic Health Evaluation II score of 10 or above, who are ready to be transferred to the surgical ward within 24 h of surgery are allocated to either intermediate care for 48 h, or surgical ward care. The primary outcome measure is all-cause 30-day mortality. We aim to enrol 400 patients in seven Danish hospitals. The sample size allows us to detect or refute a 34% relative risk reduction of mortality with 80% power. Discussion This trial evaluates the benefits and possible harm of intermediate care. The results may potentially influence the survival of many high-risk surgical patients. As a pioneer trial in the area, it will provide important data on the feasibility of future large-scale randomised clinical trials evaluating different levels of postoperative care.

We aimed to assess the impact of goal directed therapy (GDT targeting cardiac index (CI and oxygen extraction ratio (O 2 ER on outcomes of high-risk patients undergoing abdominal surgery. Methods: In a prospective randomised trial, forty patients (American Society of Anaesthesiologists II and III undergoing major abdominal surgeries were randomised into two groups. In-Group A mean arterial pressure ≥ 65 mmHg, central venous pressure ≥ 8-10 mmHg, urine output ≥ 0.5 mL/kg/h and central venous oxygen saturation ≥ 70% were targeted intra-operatively and 12 h postoperatively. In-Group-B (enhanced GDT, in addition to the monitoring in-Group-A, CI ≥ 2.5 L/min/m 2 and O 2 ER ≤ 27% were targeted. The end-points were lactate levels and base deficit during and after surgery. The secondary end points were length of Intensive Care Unit (ICU and hospital stay and postoperative complications. Wilcoxon Mann Whitney and Chi-square tests were used for statistical assessment. Results: Lactate levels postoperatively at 4 and 8 h were lower in-Group-B (P < 0.05. The mean base deficit at 3, 4, 5 and 6 h intra-operatively and postoperatively after 4, 8 and 12 h were lower in-Group-B (P < 0.05. There were no significant differences in ICU stay (2.10 ± 1.52 vs. 2.90 ± 2.51 days or hospital stay (10.85 + 4.39 vs. 13.35 + 6.77 days between Group A and B. Conclusions: Implementation of enhanced GDT targeting CI and OER was associated with improved tissue oxygenation.

    2003-10-01

    This randomized study was designed to compare the effectiveness of bilateral interpleural analgesia with lumbar epidural analgesia, on postoperative pain relief in upper abdominal surgery. The studied patients were randomely allocated into either interpleural group "IP" (n = 15) or epidural group "EP" (n = 15). In "IP" group, preanesthetic bilateral interpleural block was done using a mixture of bupivacaine 0.5% (0.8 mg/kg) and 2 mg morphine diluted to 50 ml saline for each side. In "EP" group, the same mixture-diluted in 20 ml saline-was injected in the epidural space (L2-3). The general anesthetic technique was the same in both groups. Hemodynamic, gasometric, verbal pain score (VPS) values and complications were compared in both techniques. Heart rate (HR) and mean arterial pressure (MAP) readings were in the accepted normal range in the perioperative period although significant lower readings were detected in "EP" group. No significant differences were displayed in blood gasometric variables between the two groups. There were considerable level of analgesia in both groups in the postoperative period although "EP" analgesia was superior to "IP". More pain free patients (9 versus 4) and significant lower consumption of nalbuphine were detected in "EP" group. The results of this study indicate that bilateral "IP" analgesia may offer a satisfactory analgesia for upper abdominal surgery when the use of other analgesic techniques may be contraindicated.

  6. Patterns of Brain Activation and Meal Reduction Induced by Abdominal Surgery in Mice and Modulation by Rikkunshito.

    Lixin Wang

    Full Text Available Abdominal surgery inhibits food intake and induces c-Fos expression in the hypothalamic and medullary nuclei in rats. Rikkunshito (RKT, a Kampo medicine improves anorexia. We assessed the alterations in meal microstructure and c-Fos expression in brain nuclei induced by abdominal surgery and the modulation by RKT in mice. RKT or vehicle was gavaged daily for 1 week. On day 8 mice had no access to food for 6-7 h and were treated twice with RKT or vehicle. Abdominal surgery (laparotomy-cecum palpation was performed 1-2 h before the dark phase. The food intake and meal structures were monitored using an automated monitoring system for mice. Brain sections were processed for c-Fos immunoreactivity (ir 2-h after abdominal surgery. Abdominal surgery significantly reduced bouts, meal frequency, size and duration, and time spent on meals, and increased inter-meal interval and satiety ratio resulting in 92-86% suppression of food intake at 2-24 h post-surgery compared with control group (no surgery. RKT significantly increased bouts, meal duration and the cumulative 12-h food intake by 11%. Abdominal surgery increased c-Fos in the prelimbic, cingulate and insular cortexes, and autonomic nuclei, such as the bed nucleus of the stria terminalis, central amygdala, hypothalamic supraoptic (SON, paraventricular and arcuate nuclei, Edinger-Westphal nucleus (E-W, lateral periaqueduct gray (PAG, lateral parabrachial nucleus, locus coeruleus, ventrolateral medulla and nucleus tractus solitarius (NTS. RKT induced a small increase in c-Fos-ir neurons in the SON and E-W of control mice, and in mice with surgery there was an increase in the lateral PAG and a decrease in the NTS. These findings indicate that abdominal surgery inhibits food intake by increasing both satiation (meal duration and satiety (meal interval and activates brain circuits involved in pain, feeding behavior and stress that may underlie the alterations of meal pattern and food intake inhibition

    2006-01-01

    AIM: To investigate distal small bowel motility and lipid absorption in patients following elective abdominal aortic aneurysm (AAA) repair surgery.METHODS: Nine patients (aged 35-78 years; body mass index (BMI) range: 23-36 kg/m2) post-surgery for AAA repair, and seven healthy control subjects (20-50 years;BMI range: 21-29 kg/m2) were studied. Continuous distal small bowel manometry was performed for up to 72 h, during periods of fasting and enteral feeding (Nutrison(R)). Recordings were analyzed for the frequency,origin, length of migration, and direction of small intestinal burst activity. Lipid absorption was assessed on the first day and the third day post surgery in a subset of patients using the 13C-triolein-breath test, and compared with healthy controls. Subjects received a 20-min intraduodenal infusion of 50 mL liquid feed mixed with 200 μL 13C-triolein. End-expiratory breath samples were collected for 6 h and analyzed for 13CO2 concentration.RESULTS: The frequency of burst activity in the proximal and distal small intestine was higher in patients than in healthy subjects, under both fasting and fed conditions (P<0.005). In patients there was a higher proportion of abnormally propagated bursts (71% abnormal), which began to normalize by d 3 (25% abnormal) post-surgery.Lipid absorption data was available for seven patients on d 1 and four patients on d 3 post surgery. In patients,absorption on d 1 post-surgery was half that of healthy control subjects (AUC 13CO2 1323 ± 244 vs 2 646 ±365;P< 0.05, respectively), and was reduced to the one-fifth that of healthy controls by d 3 (AUC 13CO2 470 ± 832 vs 2646 ± 365; P< 0.05, respectively).CONCLUSION: Both proximal and distal small intestinal motor activity are transiently disrupted in critically ill patients immediately after major surgery,with abnormal motility patterns extending as far as the ileum. These motor disturbances may contribute to impaired absorption of enteral nutrition, especially when

    Long-term follow-up of patients born with classical bladder exstrophy-epispadias complex (EEC) reveals that many of them suffer from poor self-image, and the aesthetic aspects of the genitalia and lower abdomen acquire greater significance with age. In this article, we review the aesthetic outcomes in performing puboplasty, umbilicoplasty, and genitoplasty in patients born with EEC. Retrospective review of the cosmetic and functional outcomes in 116 patients born with EEC treated by puboplasty, umbilicoplasty, or genitoplasty was performed. Satisfaction with the cosmetic and functional outcomes of these three reconstructive surgeries was high following initial reconstructive efforts (> 90%). Attention to cosmesis during abdominal wall and genital reconstruction for EEC helps to improve a patient's perception of body image and self-esteem. Our experience with these procedures over the past 25 years demonstrated that the efforts directed toward aesthetics have been well worthwhile. PMID:16527001

  10. Venous thrombosis after abdominal surgery. A comparison between subcutaneous heparin and antithrombotic stockings, or both

    In an open controlled study, 248 consecutive patients (age more than 40 yrs) admitted for major abdominal surgery were randomized to one of three prophylactic antithrombotic treatments. Eighty-five patients received subcutaneous heparin, 74 patients had graduated compression stockings to the knee (TED stockings), and 89 patients had both subcutaneous heparin and stockings. Treatment began on the evening before operation and continued to complete mobilization, or for not less than five days postoperatively. On the fourth or fifth postoperative day, the patients underwent a /sup 99m/Tc-plasmin test of the lower limbs as a test for deep vein thrombosis. There were 29.7% positive tests in the stocking group, 29.4% in the group with heparin prophylaxis, and 25.8% in the combined group. Differences between treatments were not statistically significant

    Objective To retrospectively analyze and compare conservative versus surgical treatment of patients with fulminant acute pancreatitis (FAP) plus abdominal compartment syndrome (ACS). Methods From January 1998 to September 2005, 21 patients with FAP plus ACS were retrospectively analyzed. Ten patients were conservatively treated by means of intensive care medicine without surgery, and 11 patients received open surgical management and suction drainage. Results Seven of the 10 non-surgical patients died, comprising one with mild, four with moderate and two with severe ACS (70% mortality rate). Of the 11 patients receiving open surgical management in the early phase (within 3 days of disease initiation), three died, comprising one with moderate and two with severe ACS (27.3% mortality rate). The difference in mortality rates was found to be statistically significant. Conclusion Our data indicate patients suffering FAP with severe ACS should be treated with open management of the abdomen in the early phase (within 3 days), even in the absence of infection. This approach appears superior to that of conservative management. Surgical treatment resulted in abdominal decompression and subsequently significantly decreased the mortality rate and improved overall prognosis.

    Full Text Available PURPOSE: The objectives of this study were to compare the effects of caudal dexmedetomidine combined with Ropivacaine to provide postoperative analgesia in children and also to establish its safety in the pediatric patients. METHODS: In a randomized, prospective, parallel group, double-blinded study, 80 children of 1 year to 6years posted for lower abdominal surgeries were recruited and allocated into two groups: Group RD (n=40 received 0.25% Ropivacaine 1 ml/kg with dexmedetomidine2 μg/kg, making the volume to 0.5 ml and Group R (n=40 received 0.25% Ropivacaine1 ml/kg + 0.5 ml normal saline. Induction of anesthesia was achieved with Inj. Ketamine 2mg/kg + Inj. Succinylcholine 2mg/kg. Intubated with appropriate-sized Endotracheal tube and caudal block was performed in all patients. Maintained with 66% nitrous oxide in Oxygen and isoflurane 0.2-0.4%.Post-operative pain assessed with FLACC score. RESULTS: The duration of postoperative analgesia recorded a mean of 339 minutes (5.6hrs ± 2.4 hrs. in Group R compared with 884 minutes (14.7 hrs. ±5hrs in Group RD, with a p value of <0.001. Group RD patients achieved a statistically significant higher FLACC score compared with Group RD patients. The peri-operative hemodynamics were stable among both the groups. CONCLUSION: Caudal dexmedetomidine (2 μg/kg with 0.25%Ropivacaine (1 ml/kg for pediatric lower abdominal surgeries provides significant postoperative pain relief and better quality of sleep and a prolonged duration of arousable sedation.

There are several different clinical variations in the approaches used for achieving analgesia via TAP infiltration, and methods for identification of the TAP have evolved considerably since the landmark-guided technique was first described in 2001. There are many factors that impact the analgesic outcomes following TAP infiltration, and the various nuances of this technique have led to debate regarding procedural classification of TAP infiltration. Based on our current understanding of fascial and neuronal anatomy of the anterior abdominal wall, as well as available evidence from studies assessing local anesthetic spread and cutaneous sensory block following TAP infiltration, it is clear that TAP infiltration techniques are appropriately classified as field blocks. While the objective of peripheral nerve block and TAP infiltration are similar in that both approaches block sensory response in order to achieve analgesia, the technical components of the two procedures are different. Unlike peripheral nerve block, which involves identification or stimulation of a specific nerve or nerve plexus, followed by

    The aim of the study is to utilize electrical impedance tomography (EIT) to guide positive end-expiratory pressure (PEEP) and to optimize oxygenation in patients undergoing laparoscopic abdominal surgery.Fifty patients were randomly assigned to the control (C) group and the EIT (E) group (n = 25 each). We set the fraction of inspired oxygen (FiO2) at 0.30. The PEEP was titrated and increased in a 2-cm H2O stepwise manner, from 6 to 14 cm H2O. Hemodynamic variables, respiratory mechanics, EIT images, analysis of blood gas, and regional cerebral oxygen saturation were recorded. The postoperative pulmonary complications within the first 5 days were also observed.We chose 10 cm H2O and 8 cm H2O as the "ideal" PEEP for the C and the E groups, respectively. EIT-guided PEEP titration led to a more dorsal shift of ventilation. The PaO2/FiO2 ratio in the E group was superior to that in the C group in the pneumoperitoneum period, though the difference was not significant (330 ± 10 vs 305.56 ± 4 mm Hg; P = 0.09). The C group patients experienced 8.7% postoperative pulmonary complications versus 5.3% among the E group patients (relative risk 1.27, 95% confidence interval 0.31-5.3, P = 0.75).Electrical impedance tomography represents a new promising technique that could enable anesthesiologists to assess regional ventilation of the lungs and optimize global oxygenation for patients undergoing laparoscopic abdominal surgery.

    2016-06-01

    To determine impact of obesity on recovery parameters and pulmonary functions of women undergoing major abdominal gynecological surgeries. Eighty women undergoing major gynecological surgeries were included in this study. Anesthesia was induced by remifentanil bolus, followed by propofol and cisatracurium to facilitate oro-tracheal intubation and was maintained by balanced anesthesia of remifentanil intravenous infusion and sevoflurane in oxygen and air. Time from discontinuation of maintenance anesthesia to fully awake were recorded at 1-min intervals and time from discontinuation of anesthesia until patient was transferred to post-anesthesia care unit (PACU) and discharged from PACU was also recorded. Pulmonary function tests were performed before surgery and repeated 4 h, days 1, 2 and 3 post-operative for evaluation of forced vital capacity, forced expiratory volume in 1 s and peak expiratory flow rate. Occurrence of post-operative complications, re-admission to ICU, hospital stay and morbidities were also recorded. Induction of anesthesia using remifentanil bolus injection resulted in significant decrease of heart rate and arterial pressures compared to pre-operative and pre-induction values. Recovery times were significantly shorter in obese compared to morbidly obese women. Post-operative pulmonary function tests showed significant deterioration compared to pre-operative measures but showed progressive improvement through first 3 post-operative days. Hospital stay was significantly shorter for obese compared to morbid obese women. Obesity delays recovery from general anesthesia, adversely affects pulmonary functions and increases post-operative complications. Remifentanil infusion and sevoflurane could be appropriate combination for obese and morbidly obese women undergoing major surgeries. PMID:26072156

    2014-01-01

    Background General anesthesia usually requires mechanical ventilation, which is traditionally accomplished with constant tidal volumes in volume- or pressure-controlled modes. Experimental studies suggest that the use of variable tidal volumes (variable ventilation) recruits lung tissue, improves pulmonary function and reduces systemic inflammatory response. However, it is currently not known whether patients undergoing open abdominal surgery might benefit from intraoperative variable ventila...

    Full Text Available OBJECTIVES : We aimed to evaluate the preemptive analgesic properties of pregabalin, an anticonvulsant drug used in clinical practice for the treatment of neuropathic pain. METHOD S : This study was performed on 40 patients from ASA I - II risk group aged 18 - 60 years which underwent lower abdominal surgeries. Group I received 300 mg pregabalin and Group II was given a placebo in oral capsule form. Visual analog scale (VAS scores, morphine consumption and side effects of all patients were recorded at 1, 4, 8, 12 and 24 hour s postoperatively. When Aldrette recovery score reached 9, morphine 0.75mcg/kg was given as rescue analgesia. RESULTS : There was no difference observed in the first analgesic requirement time values between the two groups (p>0.05. A statistically signific ant decrease was observed in the VAS scores of the pregabalin group at 1, 4, 12 and 24 hours after surgery (p0.05. CONCLUSION : Our study demonstrated that a 300 mg pregabalin administered preoperatively is an ef ficient and safe agent for preemptive analgesia. Premedication with pregabalin reduces postoperative pain scores and total analgesic consumption without increasing sedation or other side effects in the postoperative period.

    2006-04-01

    We investigated the effects of antithrombin on coagulation, fibrinolysis, and production of cytokines and adhesion molecules in abdominal aortic aneurysm repair surgery. Sixteen patients for Y-shaped graft replacement of abdominal aortic aneurysm were divided into an antithrombin group and a control group. In the antithrombin group, 3000 U antithrombin was infused over 30 min before heparin administration and 24 h later. White blood cell counts, platelet counts, prothrombin time ratio, and serum concentrations of antithrombin, polymorphonuclear leukocyte elastase, interleukin (IL)-1beta, IL-6, IL-8, tumor necrosis factor-alpha, and adhesion molecules, and variables of coagulation and fibrinolysis were measured before surgery, at the end of surgery, and 1 and 2 days after surgery. The antithrombin concentration decreased in the control group, whereas it increased in the antithrombin group with significant differences between the groups. Prothrombin time ratio, concentrations of d-dimer, thrombin-antithrombin complex, and intercellular adhesion molecule-1 increased only in the control group and polymorphonuclear leukocyte elastase, IL-6, tumor necrosis factor-alpha, and vascular cell adhesion molecule-1 increased in both groups. They were significantly less in the antithrombin group except for intercellular adhesion molecule-1. In conclusion, antithrombin could decrease hypercoagulation and inflammatory activation during abdominal aortic aneurysm surgery, which may decrease adverse events. PMID:16551889

  1. On the interpretation of the independent components underlying the abdominal phonogram: a study of their physiological relevance

    Recorded by positioning a sensitive acoustic sensor over the maternal womb, the abdominal phonogram is a signal that contains valuable information for foetal surveillance (e.g. heart rate), which is hidden by maternal and environmental sources. To recover such information, previous work used single-channel independent component analysis (SCICA) to separate the abdominal phonogram into statistically independent components (ICs) that, once acquired, must be objectively associated with the real sources underlying the abdominal phonogram—either physiological or environmental. This is a typical challenge for blind source separation methodologies and requires further research on the signals of interest to find a suitable solution. Here, we have conducted a joint study on 75 sets of ICs by means of statistical, spectral, complexity and time-structure analysis methods. As a result, valuable and consistent characteristics of the components separated from the abdominal phonogram by SCICA have been revealed: (1) the ICs are spectrally disjoint and sorted according to their frequency content, (2) only the ICs with lower frequency content present strong regular patterns and (3) such regular patterns are driven by well-known physiological processes given by the maternal breathing rate, the maternal heart rate and the foetal heart rate. This information was so promising that it has been used in current work for automatic classification of ICs and recovery of the traces of the physiological sources underlying the abdominal phonogram. Future work will look for the extraction of information useful for surveillance (e.g. heart rate), not only about foetal well-being, but also about maternal condition. (paper)

  2. Percutaneous Transhepatic Drainage of Inaccessible Abdominal Abscesses Following Abdominal Surgery Under Real-Time CT-Fluoroscopic Guidance

    This study evaluated the safety, feasibility, and clinical utility of transhepatic drainage of inaccessible abdominal abscesses retrospectively under real-time computed tomographic (CT) guidance. For abdominal abscesses, 12 consecutive patients received percutaneous transhepatic drainage. Abscesses were considered inaccessible using the usual access route because they were surrounded by the liver and other organs. The maximum diameters of abscesses were 4.6-9.5 cm (mean, 6.7 ± 1.4 cm). An 8-Fr catheter was advanced into the abscess cavity through the liver parenchyma using real-time CT fluoroscopic guidance. Safety, feasibility, procedure time, and clinical utility were evaluated. Drainage catheters were placed with no complications in abscess cavities through the liver parenchyma in all patients. The mean procedure time was 18.8 ± 9.2 min (range, 12-41 min). All abscesses were drained. They shrank immediately after catheter placement. In conclusions, this transhepatic approach under real-time CT fluoroscopic guidance is a safe, feasible, and useful technique for use of drainage of inaccessible abdominal abscesses.

  4. Effect of Dex medetomidine on Neuromuscular Blockade in Patients Undergoing Complex Major Abdominal or Pelvic Surgery

    Dex medetomidine is a highly selective α2 agonist with anesthetic, analgesic and sympatholytic properties. Its neuromuscular effects in humans are unknown. This study evaluates the effect of dex medetomidine on neuromuscular block and hemodynamics during thiopental/ isoflurane anesthesia for patients with complex abdominal or pelvic surgery. Patients and methods: During thiopental/isoflurane anesthesia, the rocuronium infusion rate was adjusted in 20 complex surgery patients to maintain a stable first response (T1) in the train of four sequence of 50% ± 3 of the pre-rocuronium value. Dex medetomidine was then administered by infusion pump, targeting a plasma dex medetomidine concentration of 0.6 ng/dL for 45 min. The evoked mechanical responses of the adductor pollicis responses (T1 response and T4/T1 ratio), systolic blood pressure, diastolic blood pressure and heart rate (HR) were measured during the dex medetomidine infusion using repeated measures analysis of variance. Plasma levels ranged from 0.73 to 1.38 ng/mL. Results: T1 values decreased during the infusion from 55(ρ2 to 38±9 ((ρ< 0.05). T4/Tl values did not change during the infusion. Dex medetomidine increased SBP (ρ< 0.001) and decreased HR ((ρ< 0.05) (10 min median values) during the infusion compared with values before the infusion. This study demonstrated that dex medetomidine decreased T1, increased SBP and decreased HR during thiopental/isoflurane anesthesia. Conclusion: We conclude that dex medetomidine induced direct vasoconstriction may alter pharmacokinetics of rocuronium, therefore increasing plasma rocuronium concentration. Although these effects were statistically significant, further studies should be held for understanding and characterizing the peripheral vasoconstrictive effects of a2 agonists that allow better management and determination of drug dosing regimens

    Full Text Available INTRODUCTION : One very important complication of abdominal surgeries is postoperative ileus which results in severe patient discomfort, prolonged hospitalization, and enhanced treatment cost. This study was conducted with an aim to analyze the clinical outcome of effe ct of chewing gum mainly to avoid post - operative paralytic ileus in post - operative patients of abdominal surgeries . MATERIAL AND METHODS : In this study total 200 patients were included, 100 were cases and remaining were controls. The cases were given chewing gum to chew after the surgery while the controls were allowed to heal without chewing gums in conventional style and both were observed hourly for clinical outcome. RESULTS : Among cases the mean duration of first sound heard was 26.3 hours while am ong controls this was 38.8 hours [p<0.001], the mean duration of first flatus passed among cases was 50.7 hours while that among controls was 68.5 hours, the mean duration of first Bowel passed among cases was 92.4 hours while that among controls was 128.3 hours [p<0.001]. On comparing cases of routine with emergency surgeries, gastric with small bowel surgeries, and traumatic with pathological bowel surgeries it was observed that the first bowel sound, first flatus and first bowel passed appears significan tly earlier in routine surgeries, gastric surgeries and traumatic surgeries respectively. CONCLUSIONS: It was observed that chewing gum has significant effect over bowel motility as bowel sounds appeared significantly earlier in cases than control and tim e for first flatus passed and first bowel passed were also noted significantly earlier in cases than controls. Hospital stay of cases were found significantly lesser than control hence simple intervention like chewing can decrease the burden of disease of paralytic ileus from community.

    2003-09-01

    Full Text Available This was a randomized double-blinded study; in which 60 ASAI-II adult patients scheduled for major abdominal surgeries (colostomy, radical cystectomy, major gynecological surgery, and abdominal vascular surgery were received standard general anesthesia. Twenty minutes before the anticipated end of surgery, patients were randomized into two equal groups: dexmedetomidine group (group D and morphine group (group M. Group D received dexmedetomidine IV infusion 4µg/kg/h for 15 minutes (1µg/Kg followed by 0.4µg/kg/h for 3h. Group M received morphine sulfate IV (0.07mg/kg. All patients were given a morphine patient controlled analgesia (PCA pump in the post anesthesia care unit (PACU, delivering IV morphine 2mg with a lockout time of 5 minutes if pain score assessed through visual analog scale (VAS was more than 5 at any given 5-min assessment. During the PACU recovery period, morphine consumption; pain and sedation scores; hemodynamic variables (heart rate, mean arterial blood pressure, oxygen saturation and respiratory rate; and postoperative nausea, retching and vomiting (PONV were recorded every 30 min for 3h (study period by a member of staff blinded to the treatment. The study demonstrated that the use of dexmedetomidine led to significant decrease in the total amount of morphine consumed throughout the entire PACU recovery period (P0.05; significant decrease in mean arterial pressure (P0.05; without any significant changes in oxygen saturation (P<0.05 or respiratory rate (P<0.05. In conclusion, dexmedetomidine exhibited both analgesic and sedative properties. The associated cardiovascular protective pharmacological profile and the lack of respiratory depression made it potentially extremely interesting for postoperative analgesia after major abdominal surgeries.

  13. Core temperatures during major abdominal surgery in patients warmed with new circulating-water garment, forced-air warming, or carbon-fiber resistive-heating system

    Hasegawa, Kenji; Negishi, Chiharu; Nakagawa, Fumitoshi; Ozaki, Makoto

    2011-01-01

    Purpose It has been reported that recently developed circulating-water garments transfer more heat than a forced-air warming system. The authors evaluated the hypothesis that circulating-water leg wraps combined with a water mattress better maintain intraoperative core temperature ≥36°C than either forced-air warming or carbon-fiber resistive heating during major abdominal surgery. Methods Thirty-six patients undergoing open abdominal surgery were randomly assigned to warming with: (1) circul...

  14. A comparative study of intrathecal ropivacaine with fentanyl and L-bupivacaine with fentanyl in lower abdominal and lower limb surgeries

    Prem Swarup Vampugalla

    2015-12-01

    Conclusion: This study revealed that the intrathecal ropivacaine with fentanyl provided adequate anesthesia for lower abdominal and lower limb surgeries. Ropivacaine achieved a shorter duration of sensory and motor blockade, and a lesser degree of motor blockade when compared to L-bupivacaine. Thus, ropivacaine was justified for short duration ambulatory surgeries of lower abdominal and lower limb surgeries. Furthermore, fentanyl as an adjuvant to both ropivacaine and L-bupivacaine enhanced the duration of the sensory block. Hence, ropivacaine with fentanyl in spinal anesthesia for lower abdominal and lower limb surgeries is a better alternative compared to L-bupivacaine with fentanyl favoring day care ambulatory surgeries.

    Postoperative pleural-pulmonary changes (PPC) are very common following elective abdominal surgery, resolving without clinical manifestations in most patients. The incidence and risk factors associated are unknown. Objective: to determine the incidence of PPC and possible association with risk factors using computerized tomography (CT). Material and method: thirty seven patients submitted to elective abdominal surgery were prospectively analyzed using CT performed in the preoperative period and 48 hours after surgery. The PPC was scored from 0 to III. The risk factors evaluated were: age, sex, obesity, smoking history, alcoholism, comorbid conditions, cancer, ASA classification, duration of surgery, surgical incision type and number of days of hospitalization. Results: Pleura effusion was detected by CT in 70.3% (26/37) of the patients and pulmonary atelectasis in 75.5% (28/37). Grade I and II PPC was found in 59.5% (22/37) of the patients and grade III in 21.6% (8/37). Two (5.4%) of these patients developed serious pulmonary complications whereas one patient died. Surgery due to cancer, class ASA >2, longitudinal incision and > 15 cm showed statistical significance and were associated with pleural effusion. The hospitalization was over 2.4 longer for patients with PPC. Conclusion: PPC is frequently seen in patients submitted to abdominal surgery. The use of the CT for the detection of pulmonary atelectasis and pleural effusion proved to be effective. Most cases of PPC are self-limited, resolving without symptoms. (author)

    2016-04-01

    The aim of this study was to determine the influence of music on anxiety levels and physiologic parameters in women undergoing gynecologic surgery. This study employed a pre- and posttest experimental design with nonrandom assignment. Ninety-seven women undergoing gynecologic surgery were included in the study, where 49 were allocated to the control group (nonmusic group) and 48 were assigned to the experimental group (music group). Preoperative anxiety was measured using the State Trait Anxiety Inventory (STAI) while noninvasive instruments were used in measuring the patients' physiologic parameters (blood pressure [BP], pulse [P], and respiration [R]) at two time periods. Women allocated in the experimental group had lower STAI scores (t = 17.41, p music during the preoperative period in reducing anxiety and unpleasant symptoms in women undergoing gynecologic surgery.

    Obesity is a risk factor for surgical site infection (SSI) after abdominal procedures; however, data characterizing the risk of SSI in obese patients during abdominal procedures are lacking. We hypothesized that obesity is an independent risk factor for SSI across wound classes. We analyzed American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) data for 2011. We calculated body mass index (BMI), classifying patients according to National Institute of Health (NIH) BMI groups. We excluded records in which height/weight was not recorded and patients with BMI less than 18.5. We examined patients undergoing open abdominal procedures, performing univariate and multivariate analyses to assess the relative contribution of obesity to SSI. Study criteria were met by 89,148 patients. Obese and morbidly obese patients had significantly greater SSI rates in clean and clean-contaminated cases but not contaminated or dirty/infected cases. Logistic regression confirmed obesity and morbid obesity as being independently associated with the overall SSI development, specifically in clean [Obesity odds ratio (OR) = 1.757, morbid obesity OR = 2.544, P SSI overall, specifically in clean and clean-contaminated abdominal procedures; this is independent of diabetes mellitus. Novel techniques are needed to reduce SSI in this high-risk patient population. PMID:27097626

    2011-05-01

    Full Text Available Background: Surgery is an important stressor, which causes some harmful physiological responses such as increased breath and heart rate and blood pressure. The aim of this study was to investigate the effects of music on the anxiety and some physiological responses of patients before general surgery. Methods: A clinical trial study designed and 60 patients who were scheduled to undergo general surgery were selected using convenience sampling method in Shahid Beheshty hospitals of Kashan in 2009. They were randomly allocated into intervention and control groups. The level of anxiety was measured using Spilberger questionnaire. Blood pressure measured using mercury sphygmomanometer, respiratory and heart rate determined before music intervention. The intervention group listened to non-speech music for 20 minutes in a quiet environment. The anxiety level and physiological responses were measured again after the intervention. The same measurements were carried out for the control group without music intervention. Results: The results showed a statistical significant differences in the anxiety level as well as the systolic blood pressure in the intervention group P=0.04. There was no significant difference in heart and respiratory rate between the two groups (P=0.2, P=0.11. Conclusion: Considering the alterations in physiological responses during listening to music, we suggest music listening to be considered as an intervention to relieve preoperative anxiety and fear.

    52 patients undergoing either laparotomy or laparoscopic surgery. Three levels of PEEP were applied in random order: (1) zero (ZEEP), (2) 5 cmH2O and (3) 10 cmH2O. Pulmonary shunt and ventilation/perfusion mismatch were assessed by the automatic lung parameter estimator system. RESULTS: Pulmonary......BACKGROUND: General anaesthesia decreases pulmonary compliance and increases pulmonary shunt due to the development of atelectasis. The presence of capnoperitoneum during laparoscopic surgery may further decrease functional residual capacity, promoting an increased amount of atelectasis compared...... of 10 cmH2O. Although laparoscopic surgery was associated with a lower pulmonary compliance, increasing levels of PEEP were able to ameliorate it in both groups. CONCLUSION: Both surgeries have similar negative effects on pulmonary shunt, while the presence of capnoperitoneum reduced only the...

  6. Abdominal trauma

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

    2005-01-01

    Objective: To evaluate the predictive performance of'Diprifusor' TCI (target-controlled infusion) system for its better application in clinical anesthesia. Methods: The predictive performance of a ‘Diprifusor’ TCI system was investigated in 27Chinese patients (16 males and 11 females) during upper abdominal surgery under total intravenous anesthesia (TIVA) with propofol/fentanyl. Measured arterial propofol concentrations were compared with the values predicted by the TCI infusion system.Performance was determined by the median performance error (MDPE), the median absolute performance error (MDAPE), the divergence (the percentage change of the absolute PE with time), and the wobble (the median absolute deviation of each PE from the MDPE). Results: The median (range) values of 14.9% (-21.6%~42.9%) for MDPE, 23.3% (6.9%~62.5%) for MDAPE, -1.9%h-1 (-32.7%~23.0% h-1) for divergence, and 18.9% (4.2%~59.6%) for wobble were obtained from 227 samples from all patients.For the studied population, the PE did not increase with time but with increasing target propofol concentration, particularly following induction. Conclusions: The control of depth of anaesthesia was good in all patients undergoing upper abdominal surgical operation and the predictive performance of the ‘Diprifusor’ target controlled infusion system was considered acceptable for clinical purposes. But the relatively bigger wobble showed that the pharmacokinetic model is not so suitable and requires improvement.

    Basing on data of analysis of the hemostasis system state in the patients, suffering abdominal aorta aneurysm, a tendency for raising of postoperative soluble fibrin and D-dimer content in the blood plasm and reduction of these indices on the third day was noted. The abovementioned markers content depends on the aneurysm size, the fibrin deposits presence, the terms from clinical signs beginning to the certain therapy administration and anticoagulants application. Information about correlation between content of D-dimer and soluble fibrin in the treatment dynamics is important for determination of activation degree in the patients blood coagulation system and the thrombotic complications prognosis.

  13. Ultrasound as a decision-making tool in abdominal surgery in cows.

    Braun, Ueli

    2005-03-01

    In many patients, abdominal ultrasonography is an excellent diagnostic and prognostic tool. It aids in deciding whether the animal should undergo surgical or medical treatment or be slaughtered. This is particularly true in cattle with traumatic reticuloperitonitis (in combination with radiography of the reticulum) or with a tentative diagnosis of left or right displacement of the abomasum. Ultrasound also is an excellent aid for identification of ileus of the small and large intestine, liver abscesses, cholestasis, various urinary tract disorders, and the different forms of ascites.

    Mosinski, J David; Kirwan, John P

    2016-06-01

    Obesity is closely associated with the development of type 2 diabetes. Many strategies have been used in the past to combat these two conditions, but very few provide for stable and durable glycemic control. Bariatric surgery has emerged as a powerful tool for treating obesity and in over 70 % of cases provides a short-term cure for diabetes. While the acute metabolic effects of surgery are striking, it remains important for us to also consider the long-term effects. This review aims to summarize the chronic or long-term metabolic and physiological effects of Roux-en-Y gastric bypass (RYGB) surgery on pancreatic function, skeletal muscle and hepatic insulin sensitivity, and gastrointestinal remodeling. An increased understanding of the current state of research in these areas can provide the basis for stimulating further research that would contribute to new treatment and management strategies for obesity and diabetes.

    2015-10-01

    Full Text Available The stress response is the name given to the hormonal and metabolic changes which follow injury or trauma. The systemic reactions to surgical injury encompass a wide range of endocrinological, immunological and haematological effects. The ability of anaesthetic agents modifies the endocrine and metabolic responses have been studied enthusiastically. This research describes the endocrine and metabolic changes which occur during different types of surgical techniques, effects of anaesthetic and analgesic regimens to modify their responses. OBJECTIVES: The present study aimed to evaluate the effects of stress response on blood glucose levels and hemodynamics in patients undergoing open Laparotomy surgeries v/s laparoscopic surgeries. METHODS: Sixty surgical patients were enrolled in this clinical trial. The pulse, BP records were taken and blood sugar levels were tested peri-operatively. RESULTS: The results were analyzed and found that raise pulse rate, blood pressure and blood sugar levels due to stress in proportionate to surgical trauma, and duration of surgery under anaesthesia. Blood sugar levels gradually increased 90.5±4.88 to 115±7.18 and at post op119.4±6.93 in laparotomy group when compared to 91.07±4.93 to 118.33±5.06 and at post-op120.1±4.51 in laparoscopy group. CONCLUSION: Lap surgery causes minimum tissue injury and less stress response more so during postoperative period.

  20. Evaluation of Preemptive Use of Analgesia of The Skin, Before and After Lower Abdominal Surgery: A Prospective, Double-Blind, Randomized Clinical Trial

    P Kashefi

    2005-03-01

    Full Text Available Background: Perioperative pain is prevalent and poorly treated. Apart from that it makes the recovery from surgery unpleasent, pain often remains as a residual side effect of surgery, even though the tissue healing is complete. An essential observation is that tissue injury and the resulting nociceptor barrage initiates a cascade of events that can indelibly alter pain perception. Preemptive analgesia is the concept of initiating analgesic therapy before the onset of the noxious stimulus so as to prevent the nociceptor barrage and its consequences. However, anticipated clinical potency of preemptive analgesia, though has firmly grounded in the neurobiology of pain, has not been yet realized. As data accumulates, it has become clear that clinical studies emulating those from the laboratory and designed around a relatively narrow definition of preemptive analgesia have been largely unsupportive of its use. Nevertheless, preemptive analgesic interventions that recognize the intensity, duration, and somatotopic extent of major surgery can help reduce perioperative pain and its longer-term sequelae. surgeons spend a lot of time treating the pain of lower abdominal surgery. Methods: A total number of 48 consecutive patients who were going to undergo elective lower abdominal surgery. Were randomly assigned in two groups of 24 each. In one group the patients received an injection of 0.5 % bupivacaine in the planned skin for incision just before lower abdominal surgery, and in the other group, they received an equal amount of 0.5% bupivacaine after the surgery had been done. Pain was objectified by a numerical visual pain score, in the 24 hours following the lower abdominal surgery. Results: There were no differences in postoperative pain scores on the visual analog scale (VAS: In groups 1and 2, VAS at hour 4 were 6.37±1.13 versus 6.29±1.19; At hour 8 were 5.54 ± 1.17 versus 5.37±1.09; and at hour 12 were 4.5 ± 1.31 versus 4.45 ± 1

    2004-11-01

    Elective surgery of abdominal aortic aneurysm (AAA) sometimes leads to excessive bleeding and disseminated intravascular coagulation (DIC), even in patients with normal preoperative coagulation parameters. Coagulation screen, performed routinely before surgery is of limited value in the assessment of compensated activation of the haemostatic system. In this study, we used a number of additional tests (D-dimer, prothrombin fragment 1+2, antithrombin, and activation of fibrinolysis in the platelet poor plasma) for the diagnosis of compensated activation of the haemostatic system in AAA-patients. D-dimer and marker of thrombin generation (prothrombin fragment 1+2) positively correlated with each other (r = 0.768, P D-dimer and prothrombin fragment 1+2 decreased significantly) and resulted in the increase of platelet number and fibrinogen concentration, indicating their previous consumption. Despite differences in aneurysm diameters between the groups of 15 LMWH treated patients (mean 70.9 +/- 16 mm) and the reference group of 20 untreated AAA patients (mean 52.3 +/- 8.0 mm), intraoperative parameters (operation time, blood loss and transfusion demands) were similar.

  3. Somatoform abdominal pain in surgery: is SD worthy of surgical attention? Case reports and literature review.

    Abd Elwahab, Sami Medani

    2012-08-01

    Somatoform disorders (SD) or medically unexplained physical symptoms (MUPS) are a group of disorders that represent a group of symptoms that cannot be explained by an organic or physical pathology. These disorders are widely prevalent, and, if unrecognised, SD may lead medical professionals to embark on tests or procedures which may inflict unnecessary iatrogenic complications. Despite the high prevalence, they are only poorly included in medical training curricula, at both undergraduate and postgraduate levels. In this article, we review the literature and present two cases. The first one presented with a recurrent acute abdomen had an unnecessary CT abdomen. The second case had laparoscopy for acute right-sided abdominal pain which turned out to be normal, and was readmitted again after a short period with acute urine retention which resolved spontaneously following discussion with the patient and family. Both cases were referred for psychiatric assessment and their family doctors were informed.

  4. Abdominal CT predictors of fibrosis in patients with chronic pancreatitis undergoing surgery

    To determine which abdominal CT findings predict severe fibrosis and post-operative pain relief in chronic pancreatitis (CP). Pre-operative abdominal CTs of 66 patients (mean age 52 ± 12 years, 53 % males) with painful CP who underwent the Whipple procedure (n = 32), Frey procedure (n = 32) or pancreatic head biopsy (n = 2), between 1/2003-3/2014, were evaluated. CT was evaluated for parenchymal calcifications, intraductal calculi, main pancreatic duct dilation (>5 mm), main pancreatic duct stricture, and abnormal side branch(es). The surgical histopathology was graded for fibrosis. CT findings were evaluated as predictors of severe fibrosis and post-operative pain relief using regression and area under receiver operating curve (AUC) analysis. Thirty-eight (58 %) patients had severe fibrosis. Parenchymal calcification(s) were an independent predictor of severe fibrosis (p = 0.03), and post-operative pain relief over a mean follow-up of 1-year (p = 0.04). Presence of >10 parenchymal calcifications had higher predictive accuracy for severe fibrosis than 1-10 parenchymal calcification(s) (AUC 0.88 vs. 0.59, p = 0.003). The predictive accuracy of >10 versus 1-10 parenchymal calcifications increased after adjusting for all other CT findings (AUC 0.89 vs. 0.63, p = 0.01). Parenchymal calcification(s) independently predict severe fibrosis and are significantly associated with post-operative pain relief in CP. The presence of >10 parenchymal calcifications is a better predictor of severe fibrosis than 1-10 parenchymal calcification(s). (orig.)

  6. Indications for surgery in acute pancreatitis on the basis of abdominal CT in the early stage

    Acute pancreatitis clinically manifests various degrees of severity. In the present study, we performed a retrospective study on 39 cases of acute pancreatitis and examined the indications for surgery and infection as an aggravating factor in acute pancreatitis on the basis of CT in the early stage (about 48 hours after onset). CT in the early stage of acute pancreatitis permits objective determination of the extent of lesion enlargement. The cases could be classified into three grades: severe (CT score ≥ 6; surgical therapy), moderate (CT score = 5, 4; medical therapy possible), and mild (CT score ≤ 3; medical therapy) as determined by CT. Emergency surgery was performed in seven of 10 patients in whom pancreatitis was judged to be severe on the basis of CT and clinical findings. Of the seven, four had infection in the early stage (within 48 hours after onset). Three of the four had MOF complications and died. Two of the three patients without infection were relieved. The extent of inflammatory lesions of severe pancreatitis was severe by CT, and the CT scores were especially high in cases with infection. Infection in the early stage of acute pancreatitis was thus thought to be an serious aggravating factor. It was concluded, therefore, that, in the early stage, CT was very useful as a helpful guide to early judgement and an indicator for emergency surgery. (author)

Fifty-eight patients wereincluded to study who were evaluated with combinationof urinary US, PR and computed tomography (CT at 1month after surgery.Results: Of 58 procedures with perioperative completestone fragmentation, 49 were completely stone-free(84.4%, while fragments (≥ 3 mm were observed in 9patients and hydronephrosis was detected in 5 patients(8.6% on the CT. Of the 9 residual stones and 5 hydronephrosis,the radiologists truly diagnosed 6 stones (66.6%and 5 hydronephrosis (100% by using the combination ofUS and PR. The sensitivity, specificity, positive and negativepredictive values of US and PR for detecting presenceof residual stone and hydronephrosis were 66.6%and 100%, 98% and 98%, 85.7% and 83.3%, 94.2% and100%, respectively.Conclusions: A combination of urinary US and plain filmhas clear advantages about lack of radiation exposureover CT scan and it is a highly specific and sensitive testfor detecting hydronephrosis. However this procedurehas limited accuracy for detecting small residual stones,so we believe that CT scan is only necessary when patienthas persistent pain or sonographic evidence of hydronephrosisis present.Key words: Renal stone, plain abdominal film, retrogradeintrarenal surgery, ultrasonography

    AIM: To evaluate the surface expression of triggering receptor on myeloid cell 1 (TREM-1), class Ⅱ major histocompatibility complex molecules (HLA-DR), andthe expression of the splicing variant (svTREM-1) ofTREM-1 in septic patients and those subjected to major abdominal surgery.METHODS: Using flow cytometry, we examined the surface expression of TREM-1 and HLA-DR in peripheral blood monocytes from 11 septic patients, 7 elective gastrointestinal surgical patients, and 10 healthy volunteers. svTREM-1 levels were analyzed by RT-PCR. RESULTS: Basal expression of TREM-1 and HLA-DR in healthy volunteers was 35.91±14.75 MFI and75.8±18.3%, respectively. In septic patients, TREM-1 expression was 59.9±23.9 MFI and HLA-DR expression was 44.39±20.25%, with a significant differencebetween healthy and septic groups (P<0.05) for bothmolecules. In the surgical patients, TREM-1 and HLA-DR expressions were 56.8±20.85 MFI and 71±13.8% before surgery and 72.65±29.92 MlFI and 72.82±22.55% after surgery. TREM-1 expression was significantly different(P = 0.0087) between the samples before and aftersurgery and svTREM-1 expression was 0.8590±0.1451 MF1, 0.8820±0.1460 MF1, and 2.210±0.7873MF1 in the healthy, surgical (after surgery) and septic groups, respectively. There was a significant difference (P = 0.048) in svTREM-1 expression between the healthy and surgical groups and the septic group.CONCLUSION: TREM-1 expression is increased during systemic inflammatory conditions such as sepsis and the postoperative phase. Simultaneous low expression of HLA-DR molecules correlates with the severity of illness and increases susceptibility to infection. Additionally, TREM-1 expression is distinctly different in surgical patients at different stages of the inflammatory response before and after surgery. Thus, surface TREM-1 appears to be an endogenous signal during the course of the inflammatory response. svTREM-1 expression is significantly increased during sepsis, appearing to be

  9. Abdominal trauma

    The potential for multiple intraperitoneal and retroperitoneal organ injuries often makes accurate clinical evaluation of abdominal trauma patients difficult. Additionally, patients may be unresponsive, have unreliable abdominal physical examinations, or have concurrent serious head and cervical spine injuries which delay diagnosis of and attention to abdominal problems. In these situations radiologic abdominal imaging is often requested. To expedite patient evaluation, close cooperation between the emergency physician and the radiologist is essential. It is the clinical stability of the traumatized patient that dictates the extent of radiologic imaging. Life-threatening hypotension, positive peritoneal signs, or clear evidence of penetrating abdominal injury are indications for immediate surgery. Stable patients with signs suggesting intra-abdominal injury will benefit by further radiologic evaluation with appropriate imaging modalities. The selection of an appropriate modality in any one clinical situation depends upon many criteria including accessibility to diagnostic equipment, the sensitivity and specificity of each technique, and the expertise and preference of the attending radiologist. A suggested scheme for evaluating abdominal trauma patients is presented. Most aspects of this evaluation scheme will be discussed in depth

  10. Intensity-Modulated Whole Abdominal Radiotherapy After Surgery and Carboplatin/Taxane Chemotherapy for Advanced Ovarian Cancer: Phase I Study

    Purpose: To assess the feasibility and toxicity of consolidative intensity-modulated whole abdominal radiotherapy (WAR) after surgery and chemotherapy in high-risk patients with advanced ovarian cancer. Methods and Materials: Ten patients with optimally debulked ovarian cancer International Federation of Gynecology and Obstetrics Stage IIIc were treated in a Phase I study with intensity-modulated WAR up to a total dose of 30 Gy in 1.5-Gy fractions as consolidation therapy after adjuvant carboplatin/taxane chemotherapy. Treatment was delivered using intensity-modulated radiotherapy in a step-and-shoot technique (n = 3) or a helical tomotherapy technique (n = 7). The planning target volume included the entire peritoneal cavity and the pelvic and para-aortal node regions. Organs at risk were kidneys, liver, heart, vertebral bodies, and pelvic bones. Results: Intensity-modulated WAR resulted in an excellent coverage of the planning target volume and an effective sparing of the organs at risk. The treatment was well tolerated, and no severe Grade 4 acute side effects occurred. Common Toxicity Criteria Grade III toxicities were as follows: diarrhea (n = 1), thrombocytopenia (n = 1), and leukopenia (n = 3). Radiotherapy could be completed by all the patients without any toxicity-related interruption. Median follow-up was 23 months, and 4 patients had tumor recurrence (intraperitoneal progression, n = 3; hepatic metastasis, n = 1). Small bowel obstruction caused by adhesions occurred in 3 patients. Conclusions: The results of this Phase I study showed for the first time, to our knowledge, the clinical feasibility of intensity-modulated whole abdominal radiotherapy, which could offer a new therapeutic option for consolidation treatment of advanced ovarian carcinoma after adjuvant chemotherapy in selected subgroups of patients. We initiated a Phase II study to further evaluate the toxicity of this intensive multimodal treatment.

    Full Text Available Context: Supraglottic airway devices have been used as an alternative to tracheal intubation during laparoscopic surgery. Aims: The study was designed to compare the efficacy of Streamlined Liner of the Pharynx Airway (SLIPA for positive pressure ventilation and postoperative complications with the Laryngeal Mask Airway ProSeal (PLMA for patients undergoing lower abdominal laparoscopies under general anesthesia with controlled ventilation. Settings and Design: Prospective, crossover randomized controlled trial performed on patients undergoing lower abdominal laparoscopic surgeries. Methods: A total of 120 patients undergoing lower abdominal laparoscopic surgeries were randomly allocated into two equal groups; PLMA and SLIPA groups. Number of intubation attempts, insertion time, ease of insertion, and fiberoptic bronchoscopic view were recorded. Lung mechanics data were collected 5 minutes after securing the airway, then after abdominal insufflation. Blood traces and regurgitation were checked for; postoperative sore throat and other complications were recorded. Statistical Analysis: Arithmetic mean and standard deviation values were calculated and statistical analyses were performed for each group. Independent sample t-test was used to compare continuous variables exhibiting normal distribution, and Chi-squared test for noncontinuous variables. P value <0.05 was considered significant. Results: Insertion time, first insertion success rate, and ease of insertion were comparable in both groups. Fiberoptic bronchoscopic view was significantly better and epiglottic downfolding was significantly lower in SLIPA group. Sealing pressure and lung mechanics were similar. Gastric distension was not observed in both groups. Postoperative sore throat was significantly higher in PACU in PLMA group. Blood traces on the device were significantly more in SLIPA group. Conclusions: SLIPA can be used as a useful alternative to PLMA in patients undergoing lower

  13. Avoiding Complications in Abdominal Wall Surgery: A Mathematical Model to Predict the Course of the Motor Innervation of the Rectus Abdominis.

    Ever since its introduction, the transverse rectus abdominis myocutaneous flap has become the mainstay of autologous breast reconstruction. However, concerns regarding donor site morbidity due to the breach of abdominal wall musculature integrity soon followed. Muscle-sparing techniques, eventually eliminating the muscle from the flap all-together with the deep inferior epigastric artery perforator flap, did not eliminate the problem of abdominal wall weakness. This led to the conclusion that motor innervation might be at fault. Studies have shown that even in the presence of an intact rectus abdominis muscle, and an intact anterior rectus sheath, denervation of the rectus abdominis muscle results in significant abdominal wall weakness leading to superior and inferior abdominal bulges, and abdominal herniation. Our aim was to establish a mathematical model to predict the location of the motor innervation to the rectus abdominis muscle, and thus provide surgeons with a tool that will allow them to reduce abdominal morbidity during deep inferior epigastric artery perforator and free muscle-sparing transverse rectus abdominis myocutaneous surgery. We dissected 42 cadaveric hemiabdomens and mapped the course of the thoracolumbar nerves. We then standardized and analyzed our findings and presented them as a relative map which can be adjusted to body type and dimensions. Our dissections show that the motor innervation is closely related to the lateral vascular supply. Thus, when possible, we support the preferred utilization of the medial vascular supply, and the preservation of the lateral supply and motor innervation. PMID:26756600

  14. EFFICACY OF DEXMEDETOMIDINE AS AN ADJUVANT TO BUPIVACAINE FOR CAUDAL ANALGESIA IN PAEDIATRIC PATIENTS UNDERGOING LOWER ABDOMINAL SURGERIES

    Vijay

    2014-07-01

    Full Text Available CONTEXT: Various adjuvants such as opioids or α2 agonists are being used to improve the quality and duration of caudal analgesia with local anesthetics. Dexmedetomidine a α2 agonist is used frequently in adult patients to enhance the local anesthetic effect. However there is little literature regarding its effectiveness in pediatric caudal analgesia. The objective of this study was to assess the efficacy of dexmedetomidine when used as an adjuvant to bupivacaine in increasing the duration of caudal analgesia. AIM: The aim of this study was to investigate the effect of adding Dexmedetomidine to caudal Bupivacaine and observe the effect on the duration of analgesia in the post-operative period. SETTINGS AND DESIGN: One year hospital based Double Blind Randomized Controlled Trial. METHODS AND MATERIAL: Sixty children, aged 1-6 years, undergoing lower abdominal surgeries were included in this prospective randomized double-blind study. The patients were randomly divided into two groups: Group I received Bupivacaine (0.25% 1ml/kg plus 1 ml of normal saline in the caudal epidural space. Group II was administered Bupivacaine (0.25% 1ml/ with Dexmedetomidine 2 mcg/ ml diluted to 1 ml of normal saline in the caudal epidural space. All anesthetic and surgical techniques were standardized. Heart rate, blood pressure, oxygen saturation, respiratory rate were monitored continuously. Surgery was started 10-15 minutes after the injection and confirming adequacy of caudal block. Duration of analgesia was assessed using FLACC scale (Face, Legs, Activity, Cry, Consolability scale. The time from administration of caudal anesthesia to the first time the FLACC score equal or greater than 4 was considered as the duration of caudal analgesia. Paracetamol suppository was used as rescue analgesia with a loading dose of 40mg/kg. STATISTICAL ANALYSIS: Mann-Whitney test and Student ‘t’test was used to compare the data obtained in the two groups. RESULTS: The

  15. The role of probiotics in the prevention of severe infections following abdominal surgery.

    Stavrou, George; Giamarellos-Bourboulis, Evangelos J; Kotzampassi, Katerina

    2015-12-01

    Administration of probiotics has been proposed for various medical and surgical conditions. Their effect has been largely attributed to their ability to maintain the integrity of the intestinal mucosal barrier as well as to modulate the innate immune response. Multiple studies have demonstrated their effect in reducing infectious complications in critically ill patients, minimising bacterial translocation and increasing the secretion of anti-inflammatory cytokines. Furthermore, they have been shown to be effective in reducing infections following colorectal surgery, while at the same time preventing overgrowth of bacterial species such as Pseudomonas aeruginosa that has been implicated in the pathogenesis of anastomotic leak. Recent experimental studies have demonstrated that probiotics may decrease expression of the SOCS3 gene, which encodes the protein SOCS3 that suppresses cytokine production, implying a direct interaction of probiotics with the innate immune system. These results hold high promises for the development of new therapeutic strategies. PMID:26686273

  16. Influence of perioperative oxygen fraction on pulmonary function after abdominal surgery: a randomized controlled trial

    Staehr Anne K

    2012-07-01

    Full Text Available Abstract Background A high perioperative inspiratory oxygen fraction (FiO2 may reduce the frequency of surgical site infection. Perioperative atelectasis is caused by absorption, compression and reduced function of surfactant. It is well accepted, that ventilation with 100% oxygen for only a few minutes is associated with significant formation of atelectasis. However, it is still not clear if a longer period of 80% oxygen results in more atelectasis compared to a low FiO2. Our aim was to assess if a high FiO2 is associated with impaired oxygenation and decreased pulmonary functional residual capacity (FRC. Methods Thirty-five patients scheduled for laparotomy for ovarian cancer were randomized to receive either 30% oxygen (n = 15 or 80% oxygen (n = 20 during and for 2 h after surgery. The oxygenation index (PaO2/FiO2 was measured every 30 min during anesthesia and 90 min after extubation. FRC was measured the day before surgery and 2 h after extubation by a rebreathing method using the inert gas SF6. Results Five min after intubation, the median PaO2/FiO2 was 69 kPa [53-71] in the 30%-group vs. 60 kPa [47-69] in the 80%-group (P = 0.25. At the end of anesthesia, the PaO2/FiO2 was 58 kPa [40-70] vs. 57 kPa [46-67] in the 30%- and 80%-group, respectively (P = 0.10. The median FRC was 1993 mL [1610-2240] vs. 1875 mL [1545-2048] at baseline and 1615 mL [1375-2318] vs. 1633 mL [1343-1948] postoperatively in the 30%- and 80%-group, respectively (P = 0.70. Conclusion We found no significant difference in oxygenation index or functional residual capacity between patients given 80% and 30% oxygen for a period of approximately 5 hours.

    2006-01-01

    Full Text Available Background and purpose: Despite progresss in the techniques of surgery, there is still a lot of controversy about selection of the best technique and suture material. Many post operation complications such as infection, wound dehiscence, pain and sinus formation are related to the type of the suture used. In this study we compared the complications due to the absorbent suture (PDS with a non absorbent suture (nylon in laparotomy operation.Materials and Methods: This clinical trial was performed on 120 patients referring to Imam Khomeini hospital, Sari, 2003-2005 for laparotomy. They were randomly divided in tow groups of equal number. The incision was repaired with PDS sutures in case and with nylon suture in control group. All patients under study were followed up for one year. Data about chronic pain,wound dehiscence, infection, hernia and sinus formation were recorded and analyzed using SPSS software and Chi- square test.Results: In this study 120 patients (60 in case and 60 in control groups were enrolled. After laparotomy, the incidence of chronic pain and sinus formation in case group was significantly less than the control group. There were no significant differences between the rate of infection, hernia and wound dehiscence in the two groups.Conclusion: No significant differences in the rate of infection, hernia and wound dehiscence between two types of suture materials were observed. However, application of PDS leads to less pain and sinus formation. Therefore, it can be a better choice in surgical incisions.

    2016-07-01

    We compared the accuracy and precision of the non-invasive Nexfin(®) device for determining systolic, diastolic, mean arterial pressure and pulse pressure variation, with arterial blood pressure values measured from a radial artery catheter in 19 patients following upper abdominal surgery. Measurements were taken at baseline and following fluid loading. Pooled data results of the arterial blood pressures showed no difference between the two measurement modalities. Bland-Altman analysis of pulse pressure variation showed significant differences between values obtained from the radial artery catheter and Nexfin finger cuff technology (mean (SD) 1.49 (2.09)%, p agreement -2.71% to 5.69%). The effect of volume expansion on pulse pressure variation was identical between methods (concordance correlation coefficient 0.848). We consider the Nexfin monitor system to be acceptable for use in patients after major upper abdominal surgery without major cardiovascular compromise or haemodynamic support. PMID:27291598

Purpose: To evaluate the efficacy of epidural ketamine for postoperative pain relief in lower abdominal procedures. Materials and Methods: 50 patients undergoing inguinal herniotomy were studied in a comparative propective trial. They were divided into two groups to receive epidural ketamine 50 mg or epidural morphine 2 mg. Results: Epidural ketamine in doses to 50 mg provide adequate analgesia during 6 hours. Morphine administered epidurally obtained analgesia more than 18 hours. Conclusion: Epidurally administered ketamine is less effective than epidural morphine for postoperative analgesia, but it playes an important role in morphine-induced analgesia and during the combination with local anaesthetic.

  1. Value of a step-up diagnosis plan: CRP and CT-scan to diagnose and manage postoperative complications after major abdominal surgery

    Jennifer Straatman

    2014-12-01

    Full Text Available Postoperative complications frequently follow major abdominal surgery and are associated with increased morbidity and mortality. Early diagnosis and treatment of complications is associated with improved patient outcome. In this study we assessed the value of a step-up diagnosis plan by C-reactive protein and CT-scan (computed tomography-scan imaging for detection of postoperative complications following major abdominal surgery. An observational cohort study was conducted of 399 consecutive patients undergoing major abdominal surgery between January 2009 and January 2011. Indication for operation, type of surgery, postoperative morbidity, complications according to the Clavien-Dindo classification and mortality were recorded. Clinical parameters were recorded until 14 days postoperatively or until discharge. Regular C-reactive protein (CPR measurements in peripheral blood and on indication -enhanced CT-scans were performed. Eighty-three out of 399 (20.6 % patients developed a major complication in the postoperative course after a median of seven days (IQR 4-9 days. One hundred and thirty two patients received additional examination consisting of enhanced CT-scan imaging, and treatment by surgical reintervention or intensive care observation. CRP levels were significantly higher in patients with postoperative complications. On the second postoperative day CRP levels were on average 197.4 mg/L in the uncomplicated group, 220.9 mg/L in patients with a minor complication and 280.1 mg/L in patients with major complications (p < 0,001. CT-scan imaging showed a sensitivity of 91.7 % and specificity of 100 % in diagnosis of major complications. Based on clinical deterioration and the increase of CRP, an additional enhanced CT-scan offered clear discrimination between patients with major abdominal complications and uncomplicated patients. Adequate treatment could then be accomplished.

    2015-01-01

    Background Post-operative pulmonary complications are a significant problem following open upper abdominal surgery. Preliminary evidence suggests that a single pre-operative physiotherapy education and preparatory lung expansion training session alone may prevent respiratory complications more effectively than supervised post-operative breathing and coughing exercises. However, the evidence is inconclusive due to methodological limitations. No well-designed, adequately powered, randomised con...

    Considering the growing organ demand worldwide, it is crucial to optimize organ retrieval and training of surgeons to reduce the risk of injury during the procedure and increase the quality of organs to be transplanted. In the Netherlands, a national complete trajectory from training of surgeons in procurement surgery to the quality assessment of the procured organs was implemented in 2010. This mandatory trajectory comprises training and certification modules: E-learning, training on the job, and a practical session. Thanks to the ACCORD (Achieving Comprehensive Coordination in Organ Donation) Joint Action coordinated by Spain and co-funded under the European Commission Health Programme, 3 twinning activities (led by France) were set to exchange best practices between countries. The Dutch trajectory is being adapted and implemented in Hungary as one of these twinning activities. The E-learning platform was modified, tested by a panel of Hungarian and UK surgeons, and was awarded in July 2013 by the European Accreditation Council for Continuing Medical Education of the European Union of Medical Specialists. As a pilot phase for future national training, 6 Hungarian surgeons from Semmelweis University are being trained; E-learning platform was fulfilled, and practical sessions, training-on-the-job activities, and evaluations of technical skills are ongoing. The first national practical session was recently organized in Budapest, and the new series of nationwide selected candidates completed the E-learning platform before the practical. There is great potential for sharing best practices and for direct transfer of expertise at the European level, and especially to export this standardized training in organ retrieval to other European countries and even broader. The final goal was to not only provide a national training to all countries lacking such a program but also to improve the quality and safety criteria of organs to be transplanted. PMID:25131109

    2012-12-01

    Full Text Available Abstract Background In patients undergoing open cardiothoracic and upper abdominal surgery, postoperative pulmonary complications remain an important cause of postoperative morbidity and mortality, impacting upon hospital length of stay and health care resources. Adequate preoperative respiratory muscle strength may help protect against the development of postoperative pulmonary complications and therefore preoperative inspiratory muscle training has been suggested to be of potential value in improving postoperative outcomes. Methods/Design A systematic search of electronic databases will be undertaken to identify randomized trials of preoperative inspiratory muscle training in patients undergoing elective open cardiothoracic and upper abdominal surgery. From these trials, we will extract available data for a list of predefined outcomes, including postoperative pulmonary complications, hospital length of stay and respiratory muscle strength. We will meta-analyze comparable results where possible, and report a summary of the available pool of evidence. Discussion This review will provide the most comprehensive answer available to the question of whether preoperative inspiratory muscle training is clinically useful in improving postoperative outcomes in patients undergoing cardiothoracic and upper abdominal surgery. It will help inform clinicians working in the surgical arena of the likely effectiveness of instituting preoperative inspiratory muscle training programs to improve postoperative outcomes.

    2011-05-01

    Full Text Available Abstract Background Post-operative pulmonary complications add to the morbidity and mortality of surgical patients, in particular after general anesthesia >2 hours for abdominal surgery. Whether a protective mechanical ventilation strategy with higher levels of positive end-expiratory pressure (PEEP and repeated recruitment maneuvers; the "open lung strategy", protects against post-operative pulmonary complications is uncertain. The present study aims at comparing a protective mechanical ventilation strategy with a conventional mechanical ventilation strategy during general anesthesia for abdominal non-laparoscopic surgery. Methods The PROtective Ventilation using HIgh versus LOw positive end-expiratory pressure ("PROVHILO" trial is a worldwide investigator-initiated multicenter randomized controlled two-arm study. Nine hundred patients scheduled for non-laparoscopic abdominal surgery at high or intermediate risk for post-operative pulmonary complications are randomized to mechanical ventilation with the level of PEEP at 12 cmH2O with recruitment maneuvers (the lung-protective strategy or mechanical ventilation with the level of PEEP at maximum 2 cmH2O without recruitment maneuvers (the conventional strategy. The primary endpoint is any post-operative pulmonary complication. Discussion The PROVHILO trial is the first randomized controlled trial powered to investigate whether an open lung mechanical ventilation strategy in short-term mechanical ventilation prevents against postoperative pulmonary complications.

    2010-12-01

    Full Text Available A cirurgia abdominal alta está associada a um risco elevado de complicações pulmonares que podem ser reduzidas pelo uso criterioso de manobras terapêuticas visando a expansão pulmonar. O objetivo foi comparar duas técnicas de incentivo respiratório na recuperação da dinâmica toracoabdominal em pacientes submetidos à cirurgia abdominal alta. O grupo de estudo experimental foi constituído por 16 pacientes internados na Clínica Cirúrgica do Hospital Universitário de Santa Maria distribuídos aleatoriamente em dois grupos: o grupo 1 foi constituído por dez pacientes que usaram o dispositivo Voldyne e o grupo 2, por seis pacientes submetidos ao padrão ventilatório com inspiração fracionada em três tempos. A expansibilidade toracoabdominal foi avaliada por cirtometria antes da cirurgia e no 1º, 3º¸ e 5º dias do pós-operatório (PO. Observou-se redução significativa dos valores de cirtometria no 1º PO que, gradualmente, foram sendo recuperados, não mais havendo diferença significativa no 5o PO em relação aos valores pré-operatórios em ambos os grupos. O grupo 1 obteve significativamente melhores índices de recuperação da mobilidade toracoabdominal do que o grupo 2. Também o tempo de recuperação do grupo 1 atingiu médias mais elevadas durante todo o período de PO investigado. Embora ambas as técnicas utilizadas fossem efetivas, o incentivo inspiratório por meio do Voldyne mostrou melhores resultados na recuperação da expansibilidade pulmonar após cirurgia abdominal alta.Upper abdominal surgery is associated to increased risk of pulmonary complications, which may be lessened by judicious use of therapeutic maneuvers aimed at lung expansion. The purpose here was to compare two respiratory incentive techniques on recovery of thoracic-abdominal dynamics in patients having undergone upper abdominal surgery. Sixteen patients in such condition were randomly divided into group 1 (n=10, who did respiratory training

    2014-01-01

    Full Text Available Background: Post-operative nausea and vomiting is one of the most common and distressing complications after anesthesia and surgery. It may lead to serious post-operative complications. Ramosetron is a newer 5-HT3 receptor antagonist and has more potent and longer duration of antiemetic effects compared to first generation 5HT3 receptor antagonists. The purpose of this study was to compare the efficacy of Ramosetron for the prevention of post-operative nausea and vomiting with that of Ondansetron in patients undergoing abdominal surgeries under general anesthesia. Methods: In this randomized, double-blind study, 60 patients, 18-60 years of both genders falling under ASA I-II category scheduled for abdominal surgery were included. Group I received I.V ramosetron 0.3 mg while group II received I.V Ondansetron 4 mg at the time of extubation. The standard general anesthetic technique was used throughout. Postoperatively the incidences of nausea, vomiting, and safety assessments were performed at 1, 2, 6, and 24 h during the first 24 h after surgery. Results: There were no differences between groups with respect to patient demographics. The percentage of patients who had complete response (no PONV, and no need for another rescue antiemetic from 0 to 24 h after anesthesia was 56% with ramosetron and 33% with ondansetron. The corresponding rates at 1, 2, 6, and 24 h after anesthesia were 76% and 63%, 76% and 50%, 100 and 83%, 100 and 93%, respectively. Safety profiles of the two drugs were comparable, as no clinically serious adverse effects caused by study drugs were observed in either of the groups. Conclusion: Our study concludes that prophylactic therapy with ramosetron is highly efficacious than ondansetron in preventing PONV in patients undergoing abdominal surgery under general anesthesia.

    Low-molecular-weight heparin (LMWH) is effective in the prevention of postoperative venous thromboembolism but does it have the safety advantages over standard heparin (SH) that have been claimed? In a multicentre randomised trial in 3809 patients undergoing major abdominal surgery (1894 LMWH, 1915 SH) heparin was given preoperatively and continued for at least 5 postoperative days. Patients were assessed in the postoperative period and were followed up for at least 4 weeks, the emphasis being on safety. Major bleeding events occurred in 69 (3.6%) patients in the LMWH group and 91 (4.8%) patients in the SH group (relative risk 0.77, 95% confidence interval 0.56-1.04; p = 0.10). 93 indices of major bleeding were observed in the 69 LMWH patients and 141 in the SH patients. (p = 0.058). Severe bleeding was less frequent in the LMWH group (1.0% vs 1.9%; p = 0.02), as was wound haematoma (1.4% vs 2.7%; p = 0.007). Bleeding episodes with LMWH were less likely to lead to further surgery to evacuate a haematoma or to control bleeding, and injection site bruising was also less common in the LMWH group. No significant differences were found in the efficacy of the two agents. Perioperative death rates were 3.3% in the LMWH group and 2.5% in the SH group; pulmonary emboli were detected in 0.7% and 0.7%; and deep-vein thrombosis was diagnosed in 0.6% of patients in each group. Follow-up was done on 91% of 3699 evaluable patients. There were 19 further deaths (10 LMWH, 9 SH group) and 25 patients with thromboembolic complications (15 and 10). Of the 3 patients with fatal pulmonary emboli during follow-up 2 had received LMWH and 1 SH. The two drugs were of similar efficacy. The primary end point, the frequency of major bleeding, showed a 23% reduction in the LMWH group, but this difference was not significant. The secondary safety end points revealed that LMWH was significantly better than SH. Fatal pulmonary embolism occurs rarely (0.09%) following discharge from hospital so the

    Objectives: Incisional hernia (IH) remains a common, highly morbid, and costly complication. Modest progress has been realized in surgical technique and mesh technology; however, few advances have been achieved toward understanding risk and prevention. In light of the increasing emphasis on prevention in today's health care environment and the billions in costs for surgically treated IH, greater focus on predictive risk models is needed. Methods: All patients undergoing gastrointestinal or gynecologic procedures from January 1, 2005 to June 1, 2013, within the University of Pennsylvania Health System were identified. Comorbidities and operative characteristics were assessed. The primary outcome was surgically treated IH after index procedures. Patients with prior hernia, less than 1-year follow-up, or emergency surgical procedures were excluded. Cox hazard regression modeling with bootstrapped validation, risk factor stratification, and assessment of model performance were conducted. Results: A total of 12,373 patients with a 3.5% incidence of surgically treated IH (follow-up 32.2 ± 26.6 months) were identified. The cost of surgical treatment of IH and management of associated complications exceeded $17.5 million. Notable independent risk factors for IH were ostomy reversal (HR = 2.76), recent chemotherapy (HR = 2.04), bariatric surgery (HR = 1.78), smoking history (HR = 1.74), liver disease (HR = 1.60), and obesity (HR = 1.96). High-risk patients (20.6%) developed IH compared with 0.5% of low-risk patients (C-statistic = 0.78). Conclusions: This study demonstrates an internally validated preoperative risk model of surgically treated IH after 12,000 elective, intra-abdominal procedures to provide more individualized risk counseling and to better inform evidence-based algorithms for the role of prophylactic mesh.

  13. Nutritional Risk Screening 2002 as a Predictor of Postoperative Outcomes in Patients Undergoing Abdominal Surgery: A Systematic Review and Meta-Analysis of Prospective Cohort Studies.

    Zhen Sun

    Full Text Available The nutritional risk screening (NRS 2002 has been applied increasingly in patients who underwent abdominal surgery for nutritional risk assessment. However, the usefulness of the NRS 2002 for predicting is controversial. This meta-analysis was to examine whether a preoperative evaluation of nutritional risk by NRS 2002 provided prediction of postoperative outcomes in patients undergoing abdominal surgery.A systematic literature search for published papers was conducted using the following online databases: MEDLINE, EMBASE, the Cochrane library, EBSCO, CRD databases, Cinahl, PsycInfo and BIOSIS previews. The pooled odds ratio (OR or weight mean difference (WMD was calculated using a random-effect model or a fix-effect model.Eleven studies with a total of 3527 patients included in this study. Postoperative overall complications were more frequent in nutritional risk patients versus patients without nutritional risk (the pooled OR 3.13 [2.51, 3.90] p<0.00001. The pooled OR of mortality for the nutritional risk group and non-nutritional risk group was 3.61 [1.38, 9.47] (p = 0.009. Furthermore, the postoperative hospital stay was significant longer in the preoperative nutritional risk group than in the nutritional normal group (WMD 5.58 [4.21, 6.95] p<0.00001.The present study has demonstrated that patients at preoperative nutritional risk have increased complication rates, high mortality and prolonged hospital stay after surgery. However, NRS 2002 needs to be validated in larger samples of patients undergoing abdominal surgery by better reference method.

  14. Screening Models for Cardiac Risk Evaluation in Emergency Abdominal Surgery. I. Evaluation of the Intraoperative Period Risk based on Data from the Preoperative Period

    2008-04-01

    Full Text Available A classification of intraoperative cardio-vascular complications (CVC was performed, based on data from 466 patients subjected to emergency surgery, due to severe abdominal surgical diseases or traumas, in accordance with the severe criteria of ACC/AHA for CVC in noncardiac surgery. There were 370 intraoperative CVC registered, distributed as follows: groups with low risk (148, moderate risk (200, and high risk (22. Patient groups were formed, according to the CVC risk level, during the intraoperative period, for which the determinant factor for the group distribution of patients was the complication with the highest risk. Individual data was collected for each patient, based on 65 indices: age, physical status, diseases, surgical interventions, anaesthesiological information, intra and postoperative cardio-vascular complications, disease outcome, causes of death, cardiovascular disease anamnesis, anamnesis of all other nonsurgical diseases present, laboratory results, results from all imaging and instrumental examinations, etc. On the basis of these indices, a new distribution of the risk factors was implemented, into groups with different levels of risk of CVC during intraoperative period. This result is a solid argument, substantiating the proposal to introduce these adjustments for determining the severity of CVC in the specific conditions of emergency abdominal surgery.

    Full Text Available OBJETIVO: Estudar a morbidade respiratória nos pacientes com síndrome pulmonar obstrutiva submetidos a cirurgia abdominal alta. CASUÍSTICA E MÉTODO: Durante o pré-operatório, 196 pacientes candidatos à cirurgia abdominal alta eletiva responderam a um questionário padronizado e logo em seguida realizaram espirometria. Houve acompanhamento no pós-operatório até a alta hospitalar ou óbito. Os pacientes foram divididos em quatro grupos: 27 pacientes com DPOC (diagnóstico de bronquite crônica ou enfisema e VEF1/CVFBACKGROUND: We wanted to determine the postoperative pulmonary complicatiosn after upper abdominal surgery in patients with pulmonary obstrutive syndrome. METHODS: We have studied 196 patients prospectively analyzed in preoperative period with spirometry and followed for observation of PPC. The patients were divided in four groups: COPD - those with chronic bronchitis or emphysema and VEF1/CVF 70% (23 patients. NORMAL - patients without pulmonary disease and normal spirometry (102 patients. RESULTS: Postoperative pulmonary complication was recognized when the patient presented atelectasis with clinical or gasometric alterations; bronchospasm that needed bronchodilator therapy; respiratory failure; mechanical ventilation or orotracheal entubation more than 48 hours in postosurgery period; tracheobronchitis characterized by the presence of purulent sputum with normal x-ray; pneumonia. Patients with pulmonary obstruction had experienced higher rates of pulmonar complications (32% vs 6%,p<0,05. The presence of obstuctive lung disease was associated with an increased number of ventilator days, but was not associeted with longer intensive care unit or hospital stay. CONCLUSIONS: The incidence of postoperative pulmonary complications was strongly associated with the presence of pulmonary obstrutive syndrome.

    Full Text Available BACKGROUND This prospective randomized double-blind study was designed to compare the analgesic efficacy and safety of intrathecal midazolam and fentanyl as an additive agent to bupivacaine for lower abdominal elective surgeries. METHODS Sixty patients classified in American Society of Anesthesiologists (ASA classes I and II scheduled for lower abdominal surgeries were studied. Patients were randomly divided to receive either 12.5 mg hyperbaric bupivacaine plus 1mg midazolam (group BM, n=30 or 12.5 mg hyperbaric bupivacaine plus 25 μg fentanyl (group BF, n=30 intrathecal. RESULTS The time of onset and the duration of motor blockade were comparable among the groups while the time to sensory block regression was same in group BM and group BF. The duration of postoperative analgesia was similar in group BM and group BF. While it was same for group BM and BF. Symptoms of pruritus and vomiting was more in group BF. CONCLUSION We conclude that midazolam is as effective as fentanyl in prolonging the durations of both sensory block and analgesia with less side effects.

    Laparoscopy is a well described modality that provides an accurate visual diagnosis upon which further management of intra-abdominal testes may be based. Laparoscopic ligation of spermatic vessels as stage 1 of the procedure is a natural extension of laparoscopy. A staged approach provides adequate...... viability of the intra-abdominal testis. However, it is uncertain whether the more sensitive germ cells survive this procedure in addition to the Sertoli and interstitial cells of the human testis. Survival of germ cells is a prerequisite of later fertility potential....

  18. Early inflammatory response following elective abdominal aortic aneurysm repair: A comparison between endovascular procedure and conventional, open surgery

    Marjanović Ivan

    2011-01-01

    Full Text Available Background/Aim. Abdominal aorta aneurysm (AAA represents a pathological enlargment of infrarenal portion of aorta for over 50% of its lumen. The only treatment of AAA is a surgical reconstruction of the affected segment. Until the late XX century, surgical reconstruction implied explicit, open repair (OR of AAA, which was accompanied by a significant morbidity and mortality of the treated patients. Development of endovascular repair of (EVAR AAA, especially in the last decade, offered another possibility of surgical reconstruction of AAA. The preliminary results of world studies show that complications of such a procedure, as well as morbidity and mortality of patients, are significantly lower than with OR of AAA. The aim of this paper was to present results of comparative clinical prospective study of early inflammatory response after reconstruction of AAA between endovascular and open, conventional surgical technique. Methods. A comparative clinical prospective study included 39 patients, electively operated on for AAA within the period of December 2008 - February 2010, divided into two groups. The group I counted 21 (54% of the patients, 58-87 years old (mean 74.3 years, who had been submited to EVAR by the use of excluder stent graft. The group II consisted of 18 (46% of the patients, 49-82 (mean 66.8 years, operated on using OR technique. All of the treated patients in both groups had AAA larager than 50 mm. The study did not include patients who have been treated as urgent cases, due to the rupture or with simptomatic AAA. Clinical, biochemical and inflamatory parameters in early postoperative period were analyzed, in direct postoperative course (number of leucocytes, thrombocytes, serum circulating levels of cytokine - interleukine (IL-2, IL-4, IL-6 and IL-10. Parameters were monitored on the zero, first, second, third and seventh postoperative days. The study was approved by the Ethics Commitee of the Military Medical Academy. Results

  20. Estudo prospectivo do derrame pleural pós-cirurgia abdominal e dos fatores de risco associados: avalição por ultra-sonografia Pleural effusion following abdominal surgery and associated risk factors: ultrasound assessment

    Luiz Antonio Rossi

    2005-04-01

    ós-operatório de cirurgia abdominal eletiva é muito freqüente. A maioria dos DPPO é autolimitada, evoluindo de modo assintomático. A ecografia na constatação do DPPO mostrou-se efetiva e sua utilização merece ser difundida.BACKGROUND: Pleural effusion is frequently seen on imaging examinations following elective abdominal surgery and has no clinical significance in most patients. This condition should be distinguished from pulmonary complications that require treatment. OBJECTIVE: To prospectively determine the incidence of pleural effusion in patients submitted to elective abdominal surgery using ultrasound (US, and to assess the possible association with risk factors related to the patients and anesthetic-surgical procedures. MATERIALS AND METHODS: Thirty-seven patients, 21 (56.8% female, and 16 (43.2% male aged 29 to 76 years submitted to elective abdominal surgery were evaluated. US was performed preoperatively and 48 hours after surgery in all patients. Associated risk factors were also assessed - age > 60 years, sex, obesity, smoking history, alcoholism and associated diseases -, and anesthetic-surgical procedure - cancer resection, class ASA > 2, duration of surgery, longitudinal incision and incision > 15 cm. Biliar lithiasis (43.2% and gastrointestinal cancer (43.2% were the main causes leading to surgery. RESULTS: The incidence of postoperative pleural effusion (PPE detected by US was 70.3% (26/37. Two of these patients (5.4% developed pulmonary complications, and one died. The risk factors age > 60 years, smoking history, alcoholism, obesity and associated diseases had no influence on the development of the PPE whereas cancer resection, class ASA > 2, longitudinal incision and incision > 15 cm were significantly statistically associated with the presence of PPE. PPE developed even during antibiotic therapy. The duration of hospitalization was more than 2.4 longer in the patients with PPE. CONCLUSION: PPE is a very frequent condition observed in patients

    2016-01-01

    Full Text Available Background: Regional anesthetic techniques can be used to alleviate postoperative pain in patients undergoing major upper abdominal surgery. Our aim was to evaluate the efficacy of bilateral ultrasound (US-guided rectus sheath (RS and transversus abdominis plane (TAP blocks for better perioperative analgesia. Patients and Methods: It is a prospective, observer-blinded, randomized clinical study. 40 eligible patients undergoing elective liver resection or Whipple procedure were included. All patients received a standardized anesthetic technique. Group 1 (n = 20 received preincisional US-guided bilateral RS and TAP blocks using 20 ml volume of bupivacaine 0.25% for each, and group 2 (n = 20 received local wound infiltration at end of surgery with 40 ml of bupivacaine 0.25%. A standardized postoperative analgesic regimen composed of intravenous paracetamol and a morphine patient-controlled analgesia (PCA. The use of intraoperative fentanyl and recovery room morphine boluses, PCA-administered morphine, pain scores as well as number of patients′ experienced postoperative nausea and vomiting in the ward at 6 and 24 h were recorded. Results: Group 1 patients received a significantly lower cumulative intraoperative fentanyl, significantly lesser boluses of morphine in postanesthesia care unit, as well, significantly lower cumulative 24 h postoperative morphine dosage than the group 2 patients. Pain visual analog scale scores were significantly lower at both 6 and 24 h postoperatively in TAP group when compared with the no-TAP group. There were no complications related to the TAP block procedures. No signs or symptoms of local anesthetic systemic toxicity were detected. Conclusion: The combination of bilateral US-guided RS and TAP blocks provides excellent perioperative analgesia for major upper abdominal surgery.

    More than 40 years ago Lynch et al. described several multigenerational breast cancer family pedigrees which demonstrated autosomal dominant inheritance of a trait(s) that increased risks for both breast and ovarian cancers. Mutation carriers in at least 90 % of these hereditary breast ovarian cancer (HBOC) syndrome families have been linked to cancer-associated mutations in the genes BRCA1 and BRCA2. This review focuses on the contributions of Lynch, colleagues and collaborators and pertinent literature, toward defining the HBOC syndrome, the cancer risks that the inherited adverse mutations convey, the gynecologic tissues and organs from which the malignancy may arise to disseminate throughout the pelvic and abdominal organs and peritoneum and how this information can be used to reduce the risk and morbidities of intra-abdominal carcinomatosis in effected individuals.

Materials and Methods: In this randomized clinical trial, 68 patients with American Society of Anesthesiologists (ASA I or II undergoing lower abdominal surgery were randomly assigned to have elective lower abdominal surgery under SA (n = 34 or GA (n = 34. The SA group received 3 cc of 0.5% hyperbaric bupivacaine (15 mg, at L3-L4 interspace intrathecally and also 2 mic/kg fentanyl and 0.15 mg/kg morphine intravenously for intraoperative analgesia. In the GA group, induction of anesthesia was carried out with Na thiopental 6 mg/kg body weight, fentanyl 2 mic/kg body weight, morphine 0.15 mg/kg, and atracurium 0.6 mg/kg body weight, and then, trachea was intubated. The primary outcome was postoperative pain scores at rest and under stress on a visual analog scale and the secondary outcome was morphine requirement by the patients. Outcome measures were recorded at 2, 4, 6, 12, and 24 h postoperatively. The duration of postanesthesia care unit (PACU and hospital stay were recorded. Intraoperative parameters, postoperative pain scores, complications, recovery time, and the duration of hospital stay at follow up were compared between the two groups. Results: Patients in SA group had significantly lower scores of a postoperative pain at rest (3.4 ± 1.6 and 4.1 ± 1.2 at 2 and 4 h postoperatively vs. 5.2 ± 1.5 and 5.8 ± 0.9 in the GA group with P < 0.05, but there were no significant differences between both groups for scores of postoperative pain at 6, 12, and 24 h. The amount of morphine requirement in 6 h postoperatively was significantly lower in the SA group (10.2 ± 4.3 mg vs. 15.6 ± 5.6 mg in the GA group

    A 26-year-old primigravida patient was referred with suspicion of ectopic pregnancy 39 days after her last menstrual period. Her serum β-human chorionic gonadotropin value was 3812 mIU/mL. As we suspected the existence of ectopic pregnancy with bilateral dermoid cysts, laparoendoscopic single-site surgery was performed. After dissection of dense pelvic adhesion, cystectomy was performed for a left ovarian dermoid cyst. Although there was a right ovary at the correct position, a parasitic dermoid cyst firmly attached to the peritoneal surface of cul-de-sac was identified. After excision of the parasitic dermoid cyst, early abdominal pregnancy tissue implanted in the peritoneal hollow of right deep pararectal space was identified under the guidance of diffusion-weighted magnetic resonance imaging and was excised. With systemic administration of methotorexate, the postoperative course was uneventful. PMID:22935307

  9. The Different Volume Effects of Small-Bowel Toxicity During Pelvic Irradiation Between Gynecologic Patients With and Without Abdominal Surgery: A Prospective Study With Computed Tomography-Based Dosimetry

    Purpose: To evaluate the effect of abdominal surgery on the volume effects of small-bowel toxicity during whole-pelvic irradiation in patients with gynecologic malignancies. Methods and Materials: From May 2003 through November 2006, 80 gynecologic patients without (Group I) or with (Group II) prior abdominal surgery were analyzed. We used a computed tomography (CT) planning system to measure the small-bowel volume and dosimetry. We acquired the range of small-bowel volume in 10% (V10) to 100% (V100) of dose, at 10% intervals. The onset and grade of diarrhea during whole-pelvic irradiation were recorded as small-bowel toxicity up to 39.6 Gy in 22 fractions. Results: The volume effect of Grade 2-3 diarrhea existed from V10 to V100 in Group I patients and from V60 to V100 in Group II patients on univariate analyses. The V40 of Group I and the V100 of Group II achieved most statistical significance. The mean V40 was 281 ± 27 cm3 and 489 ± 34 cm3 (p 3 and 132 ± 19 cm3 (p = 0.003). Multivariate analyses revealed that V40 (p = 0.001) and V100 (p = 0.027) were independent factors for the development of Grade 2-3 diarrhea in Groups I and II, respectively. Conclusions: Gynecologic patients without and with abdominal surgery have different volume effects on small-bowel toxicity during whole-pelvic irradiation. Low-dose volume can be used as a predictive index of Grade 2 or greater diarrhea in patients without abdominal surgery. Full-dose volume is more important than low-dose volume for Grade 2 or greater diarrhea in patients with abdominal surgery

  10. COMPARISON OF 0.5% ROPIVACAINE WITH DEXMEDETOMIDINE AND 0.5% BUPIVACAINE WITH DEXMEDETOMIDINE FOR EPIDURAL ANAESTHESIA IN LOWER ABDOMINAL AND LOWER LIMB SURGERIES

    2016-02-01

    Full Text Available BACKGROUND In view of the wider application of regional anaesthetic procedures in modern anaesthesia practice, there is a need for local anaesthetic with desirable properties like long duration of sensory blockade and lesser duration of motor paralysis; α-2 adrenergic agonists have both analgesic and sedative properties when used as an adjuvant in regional anaesthesia.1-6 Dexmedetomidine is a highly selective α-2 adrenergic agonist with an affinity eight times greater than that of clonidine. AIM To evaluate the clinical efficacy of 0.5% ropivacaine with dexmedetomidine by epidural route compared to 0.5% bupivacaine with dexmedetomidine by epidural route in patients undergoing lower abdominal and lower limb surgeries. MATERIALS AND METHODS In this study, 60 patients aged between 18-60 yrs. of either sex, belonging to ASA-I and II undergoing elective lower abdominal and lower limb surgeries were randomly divided into two groups. Group RD comprises of patients in whom 20mL of 0.5% ropivacaine with 30mcg. Dexmedetomidine was administered single shot epidurally. Group BD comprises of patients in whom 20mL of 0.5% bupivacaine with 30mcg. Dexmedetomidine was administered single shot epidurally. RESULTS Addition of dexmedetomidine as an adjuvant to both the groups has shortened the mean time of onset of both sensory and motor blockade. The time for two segmental regression in ropivacaine dexmedetomidine (RD group is less than that of bupivacaine dexmedetomidine (BD group, which is statistically significant. The mean time of onset of motor blockade is longer in group RD than that of the group BD, which is statistically highly significant. Duration of motor blockade in group BD is longer than that of group RD, which is statistically significant. CONCLUSION Bupivacaine with dexmedetomidine group had early onset of motor and sensory blockade with longer duration of motor blockade than that of ropivacaine with dexmedetomidine group.

    2008-01-01

    Objective To evaluate the value of immediate postoperative arterial lactate level to predict morbidity after major abdominal surgery. Methods 139 patients,73 males and 66 females, aged (64 ±14)(26-87), who underwent major abdominal surgery had their levels of arterial lactate, blood routine, blood gas and electrolytes measured after they were sent to the ICU. The physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) and the simplified acute physiology score Ⅱ (SAPS Ⅱ ) levels in the first 24-hour postoperative period were calculated Multivariate logistic regression analysis was utilized to examine the independent relationship of the initial lactate, blood gas values, and anion gap with the morbidity. Results Sixty-one cases of postoperative complications were recorded in the 47 patients (34%). The median initial lactate level of the patients with postoperative complications was 1.7 retool/L, significantly higher than that of the patients without complication (1.2mmol/L,P=0.001). Multivariate analysis showed that lactate level (odds ratio:1.81, 95% confidence interval:1.14-2.89;P=0.013)and Simplified Acute Physiology Score Ⅱ (SAPS Ⅱ (odds rstio:l.14;95% confidence interval:1.08-1.21, P < 0.001) were significantly predictive of postoperative morbidity. The optimal value of lactate to discriminate between the patients who did or did not develop postoperative complications was 2.7 mmol/L as associated with the highest sum of sensitivity and specificity (29.8% and 95.7% respectively). The lactate level more than 2.7 mmol/L was associated with 9.3-fold-higher odds for postoperative complications (95% confidence interval:2.9-30. 4, P< 0.001 ). After adjustment for SAP Ⅱ, the lactate level 2.7 mmol/L remained strongly associated with morbidity (odds ratio:5.9; 95% confidence interval:1.6-21.7; P=0.007). Conclusion Initial serum lactate level is significantly associated with postoperative complications and can

    Full Text Available BACKGROUND: There is currently no consensus on the indication and benefits of breathing exercises for the prevention of postoperative pulmonary complications PPCs and for the recovery of pulmonary mechanics. OBJECTIVE: To undertake a systematic review of randomized and quasi-randomized studies that assessed the effects of breathing exercises on the recovery of pulmonary function and prevention of PCCs after upper abdominal surgery UAS. METHOD: Search Strategy: We searched the Physiotherapy Evidence Database PEDro, Scientific Electronic Library Online SciELO, MEDLINE, and Cochrane Central Register of Controlled Trials. Selection Criteria: We included randomized controlled trials and quasi-randomized controlled trials on pre- and postoperative UAS patients, in which the primary intervention was breathing exercises without the use of incentive inspirometers. Data Collection and Analysis: The methodological quality of the studies was rated according to the PEDro scale. Data on maximal respiratory pressures MIP and MEP, spirometry, diaphragm mobility, and postoperative complications were extracted and analyzed. Data were pooled in fixed-effect meta-analysis whenever possible. RESULTS: Six studies were used for analysis. Two meta-analyses including 66 participants each showed that, on the first day post-operative, the breathing exercises were likely to have induced MEP and MIP improvement treatment effects of 11.44 mmH2O (95%CI 0.88 to 22 and 11.78 mmH2O (95%CI 2.47 to 21.09, respectively. CONCLUSION: Breathing exercises are likely to have a beneficial effect on respiratory muscle strength in patients submitted to UAS, however the lack of good quality studies hinders a clear conclusion on the subject.

    Major surgery is accompanied by extensive proteolysis of insulin-like growth factor (IGF)-binding protein-3 (IGFBP-3). Proteolysis of IGFBP-3 is generally believed to increase IGF bioavailability due to a diminished affinity of the IGFBP-3 fragments for IGFs. We have investigated 18 patients......]recombinant human IGFBP-3 degradation assay. In the GH-treated group, total IGF-I increased preoperatively by 99%. Postoperatively, total IGF-I decreased by 48% (placebo) and 52% (GH). Immunoassayable IGFBP-3 decreased by 27% (placebo) and 26% (GH). In the placebo-treated group, free IGF-I was unchanged throughout...... the study. In the GH-treated group, free IGF-I increased by 277% preoperatively and remained elevated after operation. IGFBP-3 proteolytic activity increased by 63-73% after operation. The relative elevations of free IGF-I levels despite decreased total IGF-I levels could thus relate to augmented...

    Full Text Available Background: Epidural opioids acting through the spinal cord receptors improve the quality and duration of analgesia along with dose-sparing effect with the local anesthetics. The present study compared the efficacy and safety profile of epidurally administered butorphanol and fentanyl combined with bupivacaine (B. Materials and Methods: A total of 75 adult patients of either sex of American Society of Anesthesiologist physical status I and II, aged 20-60 years, undergoing lower abdominal under epidural anesthesia were enrolled into the study. Patients were randomly divided into three groups of 25 each: B, bupivacaine and butorphanol (BB and bupivacaine + fentanyl (BF. B (0.5% 20 ml was administered epidurally in all the three groups with the addition of 1 mg butorphanol in BB group and 100 μg fentanyl in the BF group. The hemodynamic parameters as well as various block characteristics including onset, completion, level and duration of sensory analgesia as well as onset, completion and regression of motor block were observed and compared. Adverse events and post-operative visual analgesia scale scores were also noted and compared. Data was analyzed using ANOVA with post-hoc significance, Chi-square test and Fisher′s exact test. Value of P < 0.05 was considered significant and P < 0.001 as highly significant. Results: The demographic profile of patients was comparable in all the three groups. Onset and completion of sensory analgesia was earliest in BF group, followed by BB and B group. The duration of analgesia was significantly prolonged in BB group followed by BF as compared with group B. Addition of butorphanol and fentanyl to B had no effect on the time of onset, completion and regression of motor block. No serious cardio-respiratory side effects were observed in any group. Conclusions: Butorphanol and fentanyl as epidural adjuvants are equally safe and provide comparable stable hemodynamics, early onset and establishment of sensory

  3. A COMPARATIVE STUDY OF EPIDURAL BUTORPHANOL AND EPIDURAL FENTANYL FOR THE RELIEF OF POST-OPERATIVE PAIN IN LOWER ABDOMINAL AND LOWER LIMB SURGERIES

    Ashwini

    2014-11-01

    Full Text Available BACKGROUND: Epidural anaesthesia is used extensively for both intra-operative and post-operative analgesia. This prospective randomized study was conducted using opioids epidurally for post-operative analgesia. Fentanyl is a pure opioid agonist. Butorphanol tartarate which is an agonist antagonist opioid is considered safer than pure opioid agonist. Hence, we compared epidural 4mg butorphanol and epidural 100 µg fentanyl for the relief of post-operative pain. AIMS AND OBJECTIVES: To compare the onset, duration, quality of analgesia, hemodynamic effects and side effects between the 2 study drugs. MATERIALS AND METHODS: 60 patients of either sex posted for elective lower abdominal and lower limb surgeries were randomly divided into 2 groups of 30 each. Group A received butorphanol 4mg epidurally. Group B received fentanyl 100 µg epidurally. All surgeries were done under lumbar epidural anaesthesia with catheter in situ. Post-operatively when patients complained of pain, intensity of pain was assessed using visual analogue scale [VAS]. When the VAS score was > 5, Group A received butorphanol 4mg diluted to 10 ml with NS or Group B received 100 µg fentanyl epidurally diluted to 10 ml with NS. Onset, duration, quality of analgesia, hemodynamic effects and incidence of side effects were compared between the two groups and treated accordingly. RESULTS: Demographic profile was comparable in both groups. Mean time of onset of analgesia was rapid (3.22 ±0.9 (S.D min in group B compared to group A (6.38± 1.26 (S.D min. Duration of analgesia was longer in group A (344.00 ±63.39 min compared to group B (227±38.12 min. Quality of analgesia was better with group A compared to group B. There was no significant difference in hemodynamic parameters in both groups. Sedation was the main side effect in group A. Incidence of pruritis, vomiting, hypotension and respiratory depression was more in group B. CONCLUSION: Epidural Butorphanol though has a delayed

    2015-06-01

    Full Text Available BACKGROUND: Among all the spinal adjuvants, clonidine, an alpha - 2 agonist has the ability to alleviate both the somatic and visceral pain and is more potent at spinal site, favoring its neuraxial administration. OBJECTIVE: This study was done to compare the onset and duration of sensory and motor blocks, duration of analgesia, haemodynamic and adverse effects of Clonidine, buprenorhine and fentanyl used intrathecally with hyperbaric 0.5% bupuvacaine. SETTINGS & DESIGN: This prospective, randomized and comparative study included 90 ASA class 1 & 2 patients undergoing lower abdominal and lower limb surgeries under spinal anesthesia after approval from hospital ethics committee with written i nformed consent of patients. MATERIALS AND METHOD S: Patients were randomly allocated into three groups (n=30 and received 50μg of clonidine, 25μg of fentanyl and 75μg of buprenorphine respectively in group BC,BF and BB as adjuvants to 15mg of 0.5% hyperba ric bupivacaine (3.0ml. The onset time and duration of sensory and motor block, duration of analgesia, haemodynamic changes and side effects were recorded. RESULTS: The onset time of motor block and durations of sensory, motor blockade and analgesia were prolonged in - group BC as compared to group BF and BB (P.05. Group BC had lower heart rate and mean blood pressure and higher sedation score. CONCLUSION: Intr athecal Clonidine in a dose of 50μg is an effective adjuvant to local anesthetics in neuraxial blocks despite mild sedation and haemodynamic variations.

    2011-01-01

    Full Text Available INTRODUCTION: Chronic pelvic pain is a disease that directly affects the social and professional lives of women. OBJECTIVE: To estimate the prevalence of this clinical condition and to identify independent factors associated with it in women living in Ribeirão Preto, Brazil. METHODS: A one-year cross-sectional study was conducted in a population sample of 1,278 women over the age of 1,278 women over the age of 14 years. The target population was predominantly composed of women who are treated by the public health system. The questionnaire was administered by interviewers who were not linked to the city health care programs. The prevalence of the morbidity was estimated. First, we identified the significant variables associated with pelvic pain (p<0.10 and then we attributed values of 0 or 1 to the absence or presence of these variables. Logistic regression analysis was used to identify and estimate the simultaneous impact of the independent variables. The results were expressed by odds ratio and their 95% confidence interval with p<0.05. RESULTS: The disease was found in 11.5% (147/1,278 of the sample. The independent predictors were dyspareunia, previous abdominal surgery, depression, dysmenorrhea, anxiety, current sexual activity, low back pain, constipation, urinary symptoms, and low educational level. CONCLUSION: The prevalence of chronic pelvic pain in Ribeirão Preto is high and is associated with conditions that can usually be prevented, controlled, or resolved by improvement of public health policies and public education.

    Massimo Marrelli

    Full Text Available In the present work we analyzed the hormonal (salivary Cortisol; sC, immune (salivary Immunoglobulin A; sIgA and cardiovascular (Heart rate, HR, and systolic blood pressure, SBP responses induced by stress conditions in oral surgeons, randomly recruited according to their expertise level.Each surgeon performed three different surgical procedures with increasing degrees of technical difficulty and under time-limited conditions, to assess whether these variants may influence the risks of stress-induced secondary hypertension among the involved health professionals. sC and sIgA samples and cardiovascular function measurements were taken up before, during, and two hours after every surgery. Salivary samples and cardiovascular measurements were taken also during non-surgical days, as baseline controls.We observed that more experienced surgeons showed a higher stress management ability compared to those with less experience or, generally, younger, which are more exposed to the risks of developing secondary hypertension. Nevertheless, indipendently of sex and experience, oral surgeons are constantly exposed to high risks of developing stress-related diseases.On the basis of the issues addressed and the results obtained, we have highlighted the importance of the investigated stress biomarkers to monitor and to prevent stress-related pathologies among oral surgeons. This approach is aimed to emphasize the significance of these specific stress-biomarkers, which represent a powerful instrument to evaluate stress levels in oral surgeons, and that may help to reduce the most severe life-threatening risks to which they are daily exposed. In conclusion, final goal of this study is to suggest an useful guideline to monitor the stress levels of oral and maxillofacial surgeons in order to improve their quality of life, which is inevitably reflected on the quality of the performances provided and, finally, to prevent possible mistakes in their daily activities.

  9. Abdominal Assessment.

    Fritz, Deborah; Weilitz, Pamela Becker

    2016-03-01

    Abdominal pain is one of the most common complaints by patients, and assessment of abdominal pain and associated symptoms can be challenging for home healthcare providers. Reasons for abdominal pain are related to inflammation, organ distention, and ischemia. The history and physical examination are important to narrow the source of acute or chronic problems, identify immediate interventions, and when necessary, facilitate emergency department care.

  12. Major abdominal evisceration injuries in dogs and cats: 12 cases (1998-2008).

    Gower, Sara B; Weisse, Chick W; Brown, Dorothy C

    2009-06-15

    OBJECTIVE- To describe the clinical characteristics, treatment, complications, and outcome of dogs and cats treated surgically for major abdominal evisceration. DESIGN- Retrospective case series. ANIMALS- 8 dogs and 4 cats. PROCEDURES- Medical records from January 1998 through March 2008 were reviewed to identify animals that underwent surgery for major abdominal evisceration. Data regarding cause of evisceration, signalment, physiologic variables, and hematologic variables were collected. Details of treatment, duration of hospitalization, and outcome were recorded. Linear regression analysis was performed to evaluate the association of signalment, physiologic variables, and hematologic variables on the number of days of hospitalization. RESULTS- Major abdominal evisceration was secondary to a traumatic event in 4 animals and to postsurgical dehiscence in 8 animals. All animals had evisceration of the intestines and gross contamination with dirt, leaves, or litter. Two animals eviscerated the spleen, and 1 animal had a perforated colon and was leaking feces into the peritoneal cavity. All animals underwent exploratory abdominal surgery. Surgical procedures performed included resection of compromised intestine, body wall repair, diaphragmatic hernia repair, nephrectomy, splenectomy, and primary colonic repair. All animals survived to discharge from the hospital. Median duration of hospitalization was 4 days (range, 1 to 7 days). Factors associated with an increase in duration of hospitalization included evisceration secondary to trauma, high lactate concentration at time of admission, and small body size. CONCLUSIONS AND CLINICAL RELEVANCE- Despite the dramatic appearance of major abdominal evisceration in cats and dogs, prompt and aggressive medical and surgical intervention can provide a favorable outcome.

    Full Text Available Abstract Background Adhesive small intestine occlusion [ASIO] is an important cause of hospital admission placing a substantial burden on healthcare systems worldwide. Often times, ASIO is associated with significant morbidity and mortality. Icodextrin 4% solution [Adept, Shire Pharmaceuticals, UK] is a high-molecular-weight a-1,4 glucose polymer that is approved in Europe for use as an intra-operative lavage and a post-operative instillate to reduce the occurrence of post-surgery intra-abdominal adhesions. There are no randomized trials on the use of this solution to prevent adhesions after ASIO operation in current medical literature. The current clinical study evaluates the safety and effectiveness of Icodextrin 4% for decreasing the incidence, extent, and severity of adhesions in patients after abdominal surgery for ASIO. Design The study project is a prospective, randomized controlled investigation performed in the Department of Transplant, General and Emergency Surgery of St. Orsola-Malpighi University Hospital [Bologna, Italy]. The study is designed and conducted in compliance with the principles of Good Clinical Practice regulations. The study compares the results of Icodextrin 4% against a control group who does not receive anti-adhesion treatment. This randomized study uses a double-blind procedure to evaluate efficacy end points. In other words, designated third party individuals who are unaware of the treatment assigned to the patients to assess adhesion formation.

    陈哲宇; 齐清会

    2001-01-01

    Objective: To observe the clinical efficacy and mechanism of Kangyanling (KYL) in treating patients with systemic inflammatory reaction syndrome and multi-organ dysfunction syndrome (SIRS/MODS) after abdominal surgery. Methods: Eighty-two patients of SIRS/MODS after abdominal surgery were divided into two groups according to admission time, the KYL treated group (n=35) and the control group (n=47). The levels of serum C-reactive protein (CRP), plasma tumor necrosis factor α (TNFα) and interleukin-6 (IL-6) were measured at the 1st, 3rd and 7th days post-operationally. Results: The levels of CRP, TNFα and IL-6 decreased gradually after surgical operation in both groups, but the reducing velocity was shorter in the KYL group than that in the control group, so the comparison of the levels in the two groups showed significant difference on the 3rd day after operation. Conclusion:KYL could inhibit the release of inflammatory mediator and relieve the inflammatory response so as to treat post-operational SIRS/MODS effectively.

    Full Text Available Open abdomen (OA has been an effective treatment for abdominal catastrophes in traumatic and general surgery. However, management of patients with OA remains a formidable task for surgeons. The central goal of OA is closure of fascial defect as early as is clinically feasible without precipitating abdominal compartment syndrome. Historically, techniques such as packing, mesh, and vacuum-assisted closure have been developed to assist temporary abdominal closure, and techniques such as components separation, mesh-mediated traction, bridging fascial defect with permanent synthetic mesh, or biologic mesh have also been attempted to achieve early primary fascial closure, either alone or in combined use. The objective of this review is to present the challenges of these techniques for OA with a goal of early primary fascial closure, when the patient’s physiological condition allows.

  8. Abdominal Sepsis.

    De Waele, Jan J

    2016-08-01

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

  9. Childhood abdominal cystic lymphangioma

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two. Conclusions: US

    2012-12-15

    Intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) have shown clinical relevance in monitoring critically ill human beings submitted to abdominal surgery. Only a few studies have been performed in veterinary medicine. The aim of this study was to assess how pregnancy and abdominal surgery may affect IAP and APP in healthy cats. For this purpose, pregnant (n=10) and non-pregnant (n=11) queens undergoing elective spaying, and tomcats (n=20, used as controls) presented for neutering by scrotal orchidectomy were included in the study. IAP, mean arterial blood pressure (MAP), APP, heart rate and rectal temperature (RT) were determined before, immediately after, and four hours after surgery. IAP increased significantly immediately after abdominal surgery in both female groups when compared with baseline (P<0.05) and male (P<0.05) values, and returned to initial perioperative readings four hours after surgery. Tomcats and pregnant females (P<0.05) showed an increase in MAP and APP immediately after surgery decreasing back to initial perioperative values four hours later. A significant decrease in RT was appreciated immediately after laparotomy in both pregnant and non-pregnant queens. IAP was affected by abdominal surgery in this study, due likely to factors, such as postoperative pain and hypothermia. Pregnancy did not seem to affect IAP in this population of cats, possibly due to subjects being in early stages of pregnancy. PMID:23118052

    Objective To investigate the current status of postoperative pain knowledge, attitudes and behavior of abdominal surgery patients,and to provide basis for pain education and interventions. Methods A self-designed questionnaire was applied among 116 patients undergoing abdominal surgery in a grade-Ⅲ level-A hospital from November 2011 to March 2012 using convenience sampling concerning their demographic data,history of previous surgery,history of pain education and postoperative pain knowledge, belief and behavior. Results The scores of postoperative pain knowledge of the abdominal surgery patients were at a lower level(63. 03 ± 2. 68). Significant differences were observed on the scores of history of previous surgery and history of pain education(P<0. 05). Regarding to attitude, the lowest scores were detected in the four entries in behavior change disorder dimensions(2. 974 ± 0. 639,2. 991±0. 582,2. 491 ± 0. 502 and 2. 241 ± 0. 430). The scores of postoperative pain knowledge of the abdominal surgery patients were varied from 1. 517 ± 0. 502 to 3. 448 ± 0. 499. Conclusion The current status of postoperative pain knowledge of abdominal surgery patients is not ideal. There is a wrong concept of pain and use of analgesics and patients' involvement in postoperative pain control is far from satisfaction. Appropriate choice of health education, improvement of patient understanding of postoperative pain related knowledge, firm beliefs of postoperative analgesia and strengthened self-management of postoperative analgesic behavior contribute to enhance effect of pain control.%目的 了解腹部术后患者疼痛知识、信念及行为的现状,为制定疼痛健康教育对策提供参考.方法 采用方便抽样法,选取江苏省某三级甲等医院2011年11月至2012年3月行腹部手术的患者116名进行问卷调查,调查内容包括患者一般人口学资料、既往手术史和疼痛教育史及术后疼痛知识、信念、行为等.结果 患者

    2016-01-01

    [Objective] To achieve less invasive lymphadenectomy in endometrial cancer patients, we performed extraperitoneal pelvic and para-aortic lymphadenectomy via a small midline abdominal incision with retroperitoneal approach. The feasibility and safety of this method were investigated. [Methods] Inclusion criteria were 1) endometrioid adenocarcinoma diagnosed by preoperative biopsy, 2) myometrial invasion by magnetic resonance imaging, and 3) no peritoneal dissemination or distant metastasis by computed tomography. Systematic extraperitoneal dissection of pelvic and para-aortic lymph nodes was performed via an approximately 12-cm midline lower abdominal incision, after which hysterectomy and bilateral salpingo-oophorectomy were done (extraperitoneal group). The historical control group was patients who underwent standard transperitoneal lymphadenectomy followed by hysterectomy and bilateral salpingo-oophorectomy. The two groups were compared for demographic characteristics, perioperative factors, and complications. [Results] A total of 62 patients were enrolled. Demographic and clinicopathological factors showed no differences between the extraperitoneal group (n = 34) and the historical control group (n = 28). The median number of pelvic (30 vs. 28) and para-aortic (14 vs. 17) nodes dissected was also similar. However, median intraoperative blood loss was significantly smaller in the extraperitoneal group than the control group (220 vs. 573 g). Median operating time (265 vs. 323.5 min), median laparotomy time (60 vs. 295 min), and median initial flatus time (8 vs. 32 hours) were all significantly shorter in the extraperitoneal group, while complications and severe postoperative pain were significantly less frequent. [Conclusions] Our new technique was feasible, safe, and less invasive than standard laparotomy. It is an alternative to laparoscope-assisted or robotic procedures.
