    Full Text Available OBJECTIVE: To compare the effectiveness of topical local anesthesia using PRILOX cream versus local anesthesia infiltration using lignocaine and adrenaline in harvesting split skin graft. METHODS: A prospective study of 58 patients requiring split skin graft was carried. One group comprising 29 patients underwent harvesting of split skin graft under topical local anesthesia using PRILOX cream while the other group had local anesthesia infiltration using lignocaine and adrenaline. RESULTS: There were no significant differences between the 2 groups in terms of operating time, per operative pain, post-operative pain and post-operative requirement of analgesia. There was significant difference in time and pain during administration of local anesthesia and patient’s acceptability/ satisfaction with method of anesthesia. CONCLUSION: Topical local anesthesia using PRILOX cream can be used effectively for harvesting of split skin graft and is good alternative to local anesthesia infiltration.

    Full Text Available Background: More than 85% of primary hyperparathyroidism (PHPT cases are due to solitary, benign parathyroid adenomas. Recently, the success rate of Tc99m sestamibi scintigraphy in localization has made minimally invasive parathyroidectomy (MIP more prominent. MIP is as effective as conventional bilateral neck exploration. Moreover, it offers lower morbidity, cost effectiveness, and better cosmetics effects. Aim: We aimed to evaluate the success of MIP, which happens only under local anesthesia, in this study. Materials and Methods: Total of 63 patients were operated for PHPT, of which 54 had solitary adenoma. Five patients underwent bilateral neck exploration under general anesthesia for thyroid nodules or unlocalizated adenomas. A total of 49 patients underwent MIP under local anesthesia without any sedation. During MIP, gamma probe was used for all patients. The patients were followed for parathyroid functions. Results: The mean age of 49 patients with MIP (5 male, 44 female was 59 years. The mean follow-up time was 16.4 (±10.1 months (range: 2-36 months. Of the 49 patients, 47 (96% were totally cured. In 2 patients, the procedure was switched to conventional bilateral neck exploration. Temporary hypocalcaemia was noted in 4 patients. Conclusions: If the adenoma is localizated, MIP under only local anesthesia can be performed with a high success rate. Gamma probe-guided MIP under local anesthesia is an effective and safe method. It has the advantage of being minimally invasive and, therefore, it should be preferred over the conventional method.

    Thoracoscopy has been recently established as an indispensable technique for diagnosis and treatment of respiratory diseases. Although, thoracoscopy is usually applied under general anesthesia by a surgeon, it can also be applied by a chest physician under local anesthesia if the target is limited to pleural diseases. The main objective of medical thoracoscopy under local anesthesia is to establish a diagnosis of pleural effusions by means of observation and biopsy in the thoracic cavity. Our main target diseases are the pleuritis carcinomatosa, malignant mesothelioma and tuberculous pleuritis. These 3 diseases are the diseases with which medical thoracoscopy is most useful because they can be reliably diagnosed by biopsies and because early diagnosis and early treatment are essential. In case of the pneumothorax, treatment with bulla looping or cauterization may be possible, but we do not treat pneumothorax with medical thoracoscopy because it is impossible to approach and find air leaks of lesions located in or near blind spots such as the apex or mediastinal part In case of acute emphysema, it is important to release adhesions and perform effective drainage using thoracoscopy as soon as possible since deposition of fibrin tends to form quickly compartments that make drainage difficult. Scince medical thoracoscopy under local anesthesia is rapid, easy, safe, and well-tolerated procedure with an excellent diagnostic yield, it is recommended as a diagnostic procedure for cases with pleural diseases.

    Aim: To report a series of varicocelectomy performed under pure local anesthesia. Methods: From July 1988 to June 2003, a total of 575 patients, aged between 15 and 73 years, underwent high ligation of the internal spermatic vein for treatment of a varicocele testis under a regional block in which a precise injection of 0.8 % lidocaine solution was delivered to involved tissues after exact anatomical references were made. A 100-mm visual analog scale (VAS)was used to assess whether the pain level was acceptable. Results: The surgeries were bilateral in 52 cases, and unilateral in 523 cases. All were successfully performed on an outpatient basis except in the case of two patients, who were hospitalized because their surgeries required general anesthesia. Overall, 98.6 % (567/575) of men could go back to work by the end of the first post-operative week and only 8 (1.4 %) men reported feeling physical discomfort on the eighth day. The VAS scores varied from 11 mm to 41 mm with an average of (18.5 ± 11.3) mm that was regarded as tolerable. Conclusion: This study has shown varicocelectomy under local anesthesia to be possible,simple, effective, reliable and reproducible, and a safe method with minimal complications. It offers the advantages of more privacy, lower morbidity, with no notable adverse effects resulting from anesthesia, and a more rapid return to regular physical activity with minor complications.

    As described in this article, there are many advances in topical and local anesthesia. Topical and local anesthetics have played a great role in dentistry in alleviating the fears of patients, eliminating pain, and providing pain control. Many invasive procedures would not be performed without the use and advances of topical/local anesthetics. The modern-day dentist has the responsibility of knowing the variety of products on the market and should have at least references to access before, during, and after treatment. This practice ensures proper care with topical and local anesthetics for the masses of patients entering dental offices worldwide. PMID:27040295

    The equipment for local anesthesia is described in this article. Practical recommendations for the selection of the injection needle length, size, bevel type is given. Using dental needle for local anesthesia should be guided by the "one injection - one needle" rule, as a needle tends to deform by even the slightest contact with jawbone. Some of the shortcomings of carpule quality may be detected before use: signs of cup corrosion, the presence of sediment, air bubbles, rubber plunger disposition. In the case of such defects being identified all the package should not be used. The use of such carpule in clinical practice is unsafe.

    Full Text Available Introduction, definition, rationale and scope: Dermatosurgery and Cosmetic dermatology procedures are being performed by increasing number of dermatologists. Most dermatosurgeries are performed in an outpatient setting and as day care surgeries, under local anesthesia. Hence, it is important to improve patient comfort during all procedures. These guidelines seek to lay down directives in the use of local anesthesia, outline the different local anesthetics, the mode of administration, complications arising out of such procedure and management of the same. Facility for administration of local anesthesia: Local anesthesia is usually administered in the dermatologist′s procedure room. The room should be equipped to deal with any emergencies arising from administration of local anesthesia. Qualifications of local anesthesia administrator: Local anesthesia administrator is a person who applies or injects local anesthetic agent for causing analgesia. Procedures done under local anesthesia are classified as Level I office procedures and require the administrator to have completed a course in Basic Cardiac Life Support (BCLS. Evaluation of patients for topical or infiltrative anesthesia: Details of patient′s past medical history and history of medications should be noted. Allergy to any medications should be specifically enquired and documented. Patients for tumescent anesthesia need additional precautions to be observed as described in these guidelines. Methods of administration of local anesthesia: Different methods include topical anesthesia, field block, ring block, local infiltration and nerve block. Also, it includes use of local anesthetics for anesthetizing oral and genital mucosa. Tumescent anesthesia is a special form of local anesthesia used in liposuction and certain selected procedures. Local anesthetic agents: Different local anesthetics are available such as lignocaine, prilocaine, bupivacaine. The dermatologist should be aware of the

    General anesthetics are known to cause depression of the freezing point of transitions in biomembranes. This is a consequence of ideal mixing of the anesthetic drugs in the membrane fluid phase and exclusion from the solid phase. Such a generic law provides physical justification of the famous Meyer-Overton rule. We show here that general anesthetics, barbiturates and local anesthetics all display the same effect on melting transitions. Their effect is reversed by hydrostatic pressure. Thus, the thermodynamic behavior of local anesthetics is very similar to that of general anesthetics. We present a detailed thermodynamic analysis of heat capacity profiles of membranes in the presence of anesthetics. This analysis is able to describe experimentally observed calorimetric profiles and permits prediction of the anesthetic features of arbitrary molecules. In addition, we discuss the thermodynamic origin of the cutoff-effect of long-chain alcohols and the additivity of the effect of general and local anesthetics.

    The treatment of chronic pain consists of four basic concepts: Drugs (analgetic drugs, TAD, etc.), treatment by physicians (chiropraxis, massage, TENS, etc.), injection with local anesthetics and autosuggestion. Necessary for diagnosis and treatment of chronical pain is the knowledge of pathophysiology and anatomy of nerves, ligaments, muscles and the sympathetic nervous system. Diagnosis of chronical pain rarely includes roentgenograms or other technical procedures, mainly to exclude tumors, fractures or specific infections. The knowledge of pathophysiology means the knowledge of sympathetic and motoric efferences on one side and the functional examination of the anatomic structures on the other side.

    Purpose: To assess pain intensity with and without subcutaneous local anesthesia prior to intraarticular administration of contrast medium for magnetic resonance arthrography (MRa) of the shoulder. Materials and methods: This single-center study was conducted after an IRB waiver of authorization, between January 2010 and December 2012. All patients provided written, informed consent for the procedure. Our prospectively populated institutional database was searched, based on our inclusion criteria. There were 249 outpatients (178 men and 71 women; mean age, 44.4 years ± 14.6; range, 15–79) who underwent MRa and were enrolled in this study. Patients were excluded if they had received surgery of the shoulder before MRa, had undergone repeated MRa of the same shoulder, and/or had undergone MRa of both shoulders on the same day. Patients were randomly assigned into one of three groups. Patients in group A (n = 61) received skin infiltration with local anesthesia. Patients in control group B (n = 92) and group C (n = 96) did not receive local anesthesia. Pain levels were immediately assessed after the injection for MRa using a horizontal visual analog scale (VAS) that ranged from 0 to 10. To compare the pain scores of the three groups for male and female patients, a two-way analysis of variance was used. A p-value equal to or less than 0.05 was considered to indicate a significant result. Results: Patients who received local anesthesia (group A) showed a mean pain level on the VAS of 2.6 ± 2.3. In patients who did not receive local anesthetics (groups B and C), a mean pain level on the VAS of 2.6 ± 2.2 and 2.7 ± 2.4 were detected, respectively. Between the three groups, no statistically significant difference in pain intensity was detected (p = .960). There were significant differences in subjective pain perception between men and women (p = .009). Moreover, the sex difference in all three groups was equal (p = .934).

    2012-09-01

    Full Text Available Background Patients have anxiety and fear of complications due to general anesthesia.Through new instruments and local anesthetic drugs, a variety of anesthetic methods havebeen introduced. These methods keep hospital costs down and save time for patients. Inparticular, the target-controlled infusion (TCI system maintains a relatively accurate level ofplasma concentration, so the depth of anesthesia can be adjusted more easily. We conductedthis study to examine whether intravenous anesthesia using the TCI system with propofol andremifentanil would be an effective method of anesthesia in breast augmentation.Methods This study recruited 100 patients who underwent breast augmentation surgeryfrom February to August 2011. Intravenous anesthesia was performed with 10 mg/mLpropofol and 50 μg/mL remifentanil simultaneously administered using two separate modulesof a continuous computer-assisted TCI system. The average target concentration was set at2 μg/mL and 2 ng/mL for propofol and remifentanil, respectively, and titrated against clinicaleffect and vital signs. Oxygen saturation, electrocardiography, and respiratory status werecontinuously measured during surgery. Blood pressure was measured at 5-minute intervals.Information collected includes total duration of surgery, dose of drugs administered duringsurgery, memory about surgery, and side effects.Results Intraoperatively, there was transient hypotension in two cases and hypoxia in threecases. However, there were no serious complications due to anesthesia such as respiratorydifficulty, deep vein thrombosis, or malignant hypertension, for which an endotrachealintubation or reversal agent would have been needed. All the patients were discharged on theday of surgery and able to ambulate normally.Conclusions Our results indicate that anesthetic methods, where the TCI of propofol andremifentanil is used, might replace general anesthesia with endotracheal intubation in breastaugmentation surgery.

    2011-12-01

    Full Text Available Currently available local anesthetics have analgesic durations in humans generally less than 12 hours. Prolonged-duration local anesthetics will be useful for postoperative analgesia. Previous studies showed that in rats, combinations of tetrodotoxin (TTX with bupivacaine had supra-additive effects on sciatic block durations. In those studies, epinephrine combined with TTX prolonged blocks more than 10-fold, while reducing systemic toxicity. TTX, formulated as Tectin, is in phase III clinical trials as an injectable systemic analgesic for chronic cancer pain. Here, we examine dose-duration relationships and sciatic nerve histology following local nerve blocks with combinations of Tectin with bupivacaine 0.25% (2.5 mg/mL solutions, with or without epinephrine 5 µg/mL (1:200,000 in rats. Percutaneous sciatic blockade was performed in Sprague-Dawley rats, and intensity and duration of sensory blockade was tested blindly with different Tectin-bupivacaine-epinephrine combinations. Between-group comparisons were analyzed using ANOVA and post-hoc Sidak tests. Nerves were examined blindly for signs of injury. Blocks containing bupivacaine 0.25% with Tectin 10 µM and epinephrine 5 µg/mL were prolonged by roughly 3-fold compared to blocks with bupivacaine 0.25% plain (P < 0.001 or bupivacaine 0.25% with epinephrine 5 µg/mL (P < 0.001. Nerve histology was benign for all groups. Combinations of Tectin in bupivacaine 0.25% with epinephrine 5 µg/mL appear promising for prolonged duration of local anesthesia.

    Seven groups of thirty patients undergoing cataract extraction under local anesthesia were each given different combinations of local anesthesia. These varied from a maximum approach using supra-orbital, infra-orbital and facial blocks with Hyalase, orbital compression and pre-operative Acetazolamide down to a minimum group receiving purely an infra- orbital and supra-orbital block with a Ugnocaine/Bupivacaine mixture. There was no significant difference in local analgesia or in the complication rates b...

  11. A reappraisal of local anesthesia for prostate brachytherapy

    International Nuclear Information System (INIS)

    Purpose: Faced with rapidly increasing patient numbers, the authors adopted and modified a technique to perform prostate implants under local anesthesia in a radiation oncology facility. Our reasons for assembling the current report detailing 20 consecutive, unselected patients are to show how patients tolerate brachytherapy without the use of sedatives, to provide more technical detail regarding the procedure's practical aspects, and to summarize the time needed to complete its components. Materials and methods: No pre-operative medication is given. The patient is placed in the lithotomy position, using stirrups mounted on the end of the simulator table. A 5-cmx5-cm patch of perineal skin and subcutaneous tissue is anesthetized by local infiltration of 3--5 cm3 of 0.5% lidocaine, using a 25-gauge 1.5-inch needle. Immediately following injection into the subcutaneous tissues, the deeper tissues, of the pelvic floor are anesthetized by injecting 5 cm3 lidocaine solution with approximately 16 passes of a 25-gauge 1.5-inch needle entering perpendicular to the skin surface. The transrectal ultrasound (TRUS) probe of a Siemens SONOLINE Prima ultrasound machine (6.0 MHz) and a Winston-Barzell stepper unit is next positioned to reproduce the planning images and a 3.5-inch, 22-gauge spinal needle is inserted into the peripheral and a few central tracks. About 0.5 cm3 of lidocaine solution is injected into each intraprostatic track, as the needle is slowly advanced. Finally, a 7-inch 22-gauge spinal needle inserted through the skin via a 3.5-inch 18-gauge needle, is used to anesthetize to the base of the prostate under TRUS and fluoroscopic guidance. Seed placement is done with a Mick ApplicatorTM, inserting and loading one needle at a time. The number of seeds placed ranged from 60 to 118 (average: 87) and the number of needles used ranged from 14 to 20 (average: 18). For the purpose of this study, prior to walking to the simulator suite, patients were asked to rate the

    Full Text Available Abstract Background Local anesthesia is widely used for open carpal tunnel release. However, injection of local anesthesia as described by Altissimi and Mancini (1988 can interfere with endoscopic carpal tunnel release, by increasing the bulk of synovial layers and consequently result in worsening of the view. Purpose The purpose of this study was to evaluate the safety, efficacy using modified technique for application of local anesthesia. Methods 33 patients suffering from gradual increasing symptoms of carpal tunnel syndrome. The patients were also asked to evaluate the pain associated with injection as well as tourniquet during surgery using Visual Analogue Scale (VAS (ranging from 0 = no pain to 10 = maximum pain. Results One patient required additionally local anesthesia because of mild pain in the hand. The tourniquet was inflated for 13.00 (2.8 min. The pain score related to injection was 2.5 (0.8 and to tourniquet was 3.6 (0.9. Inflation of the tourniquet was well tolerated by all patients. Postoperative neurological sensory and motor deficits related to surgery and local blocks were not occurred. Conclusion Endoscopic release of the carpal tunnel syndrome in local anesthesia is effective, well tolerated and safe. This kind of application of local anesthesia did not reduce visibility.

The purpose of this study"nwas to determine the effects of inferior alveolar dental nerve blocks by comparing the two akinosi and"nconventional techniques. 80 patients (aged 15-60 years old were randomly divided into tow groups for"nextracting the mandibuler posterior teeth by akinosi and conventional techniques. Patients were all"ninjected with 1.8 ml of Lidocaine 2% plus Adernaline j^nnnn .Then the Pain Sensation during injection,"npositive aspiration, beginning time of anesthesia, duration of anesthesia depth of anesthesia, and the anesthesia of soft tissue related to sensory nerves were evaluated. The results showed that the pain sensation in conventional technique was significantly higher than that of akinosi technique. The number of positive aspirations in conventional technique (12,5% was higher than that of akinosi (5% but not significantly different. The long buccal nerve anesthesia in akinosi technique (75% was significantly higher than that of conventional technique. There was no significant difference between the two techniques for the depth of anesthesia. The success rate was 87.5% in conventional technique and 80% in akinosi technique. The average time of lips anesthesia in conventional technique was 3 minutes compared with 4 minutes in akinosi technique, which was not significantly different from each other. However, the beginning time of aneshtesia in tongue was significantly lower in conventional technique. No significant difference in the duration of anesthesia in lips and tonques between the two techniques was observed.

    Two paired randomized trials testing topical anesthesia with a eutetic mixture of local anesthetics (EMLA cream*) in vasectomy were performed. In 1 trial EMLA cream was applied on 1 side of the scrotum, while infiltration anesthesia into the skin and subcutaneous tissue with mepivacaine was used...... on the contralateral side. All but 1 of the 13 patients (p less than 0.05) preferred infiltration anesthesia because of pain as the incision reached the subcutaneous tissue. In the other trial 29 patients received EMLA cream on 1 side of the scrotum before bilateral mepivacaine infiltration. There was significantly...... less pain on the sides with the anesthetic cream (p less than 0.001). Many patients would pay the price of the cream. In conclusion, EMLA cream cannot replace but it can supplement infiltration anesthesia during vasectomy....

    2016-01-01

    A sound knowledge of anatomical variations that could be encountered during surgical procedures is helpful in avoiding surgical complications. The current article details anomalous morphology of inferior alveolar nerves encountered during routine dissection of the craniofacial region in the Gross Anatomy laboratory. We also report variations of the lingual nerves, associated with the inferior alveolar nerves. The variations were documented and a thorough review of literature was carried out. We focus on the variations themselves, and the clinical implications that these variations present. Thorough understanding of variant anatomy of the lingual and inferior alveolar nerves may determine the success of procedural anesthesia, the etiology of pathologic processes, and the avoidance of surgical misadventure.

    Full Text Available Lidocain solution 1-2% have used with or without adrenaline for skin local anesthesia. Also normal salin, diphenhydramine and bacteriostatic salin have been used. The purpose of this study was to compare the effectiveness of 1% lidocain with 0.1% lidocain in local skin anesthesia.This study was carried out by triple blind method on 140 patients that submitted to Hamedan Sina Hospital in 2000. These patients divided in two groups randomly, 70 cases received 1% lidocain and other 70 cases received 0.1% lidocain. The pain assessment score was between 0-10 that was asked from each patient and collected data analyzed by statistical methods.This study showed that 51.1% of patients that received 1% lidocain and 48.9% that received 0.1% lidocain did not have any pain during injection (P>0.05. Also 54.3% of patients that received 1% lidocain and 45.7% that received 0.1% lidocain solution did not have any pain throw the procedure (P>0.05.The effect of 0.1% lidocain solution had no much difference from 1% lidocain in skin local anesthesia and thus it is suggested to use it for wide anesthesia in skin surgeries.

    Full Text Available To present our experience of removing middle to deep orbital tumors using a combination of minimally invasive soft tissue approaches, sometimes under local anesthesia. Methods. In this retrospective case series, 30 patients (13 males and 17 females underwent tumor removal through eyelid crease (17 eyes, conjunctival (nine eyes, lateral canthal (two eyes, and transcaruncular (two eyes approaches. All tumors were located in the posterior half of the orbit. Six cases were removed under monitored anesthesia care with local block, and 24 were under general anesthesia. Results. The median (range age and follow-up duration were 48.5 (31–87 years old and 24.5 (4–375 weeks, respectively. Visual acuity and ocular motility showed improvement or no significant change in all but one patient at the latest followup. Confirmed pathologies revealed cavernous hemangioma (15 cases, pleomorphic adenoma (5 cases, solitary fibrous tumor (4 cases, neurofibroma (2 cases, schwannoma (2 cases, and orbital varix (1 case. None of the patients experienced recurrence. Conclusions. Creating a bony marginotomy increases intraoperative exposure of the deep orbit but adds substantial time and morbidity. Benign orbital tumors can often be removed safely through small soft-tissue incisions, without bone removal and under local anesthesia.

    Full Text Available Hatem A Tawfik,1 Osama R Youssef21Department of Ophthalmology, 2Department of Anesthesiology, Ain Shams University, Cairo, EgyptBackground: The purpose of this paper is to describe a simplified local anesthesia technique for external dacryocystorhinostomy (EXT-DCR.Methods: In this pilot, retrospective, noncomparative, interventional case series, 448 patients (480 eyes underwent EXT-DCR using a simplified local anesthesia technique. Nasal mucosal anesthesia was achieved using combined application of 6 mL of oxymetazoline 0.025% nasal spray and lidocaine 1% in the same spray bottle, without any packing of the nose with either pledgets or ribbon gauze. Local infiltration anesthesia consisted of subcutaneous injection of a 7 mL mixture of 2% lidocaine with 1:100,000 epinephrine injected on the flat side of the nose beneath the incision site, in addition to a second medial peribulbar injection (3 mL, 2% lidocaine without epinephrine.Results: Successful unilateral or bilateral EXT-DCR was achieved in 432/448 patients (96.4%. Four patients could not tolerate the procedure under local anesthesia and were converted to general anesthesia. Four patients required additional local anesthetic injections because of intolerable pain. Heavy sedation was essential in eight uncooperative patients because surgical manipulation was impossible. The remaining patients tolerated the procedure well. The intraoperative bleeding rate was very low except in one patient. Mean operative time was 16 minutes. Severe postoperative epistaxis was observed in four patients. Temporary anosmia developed in one patient.Conclusion: Our simplified local anesthesia approach of EXT-DCR is convenient for the patient because it avoids unnecessary nasal packing. It is also safe and effective, as evidenced by the high rate of successful completion of the procedure without conversion to general anesthesia or the need for supplemental local anesthesia.Keywords: local anesthesia, external

    Local anesthetics are the safest and most effective drugs for pain control. Over 300 million local anesthetic cartridges are administered by dentists in the United States of America annually, yet serious complications reported number but a handful. Complications are categorised as localised or systemic. Localised complications arise at the site of needle penetration or anesthetic administration while systemic complications involve the entire organism. Localised complications include needle breakage, paresthesia, trismus, haematoma and facial nerve paralysis, while systemic complications are psychogenic to the act of receiving an injection, allergy and drug overdose (toxic reaction). These potential complications are briefly described in the following paper.

    What characteristics of neural activity distinguish the awake and anesthetized brain? Drugs such as isoflurane abolish behavioral responsiveness in all animals, implying evolutionarily conserved mechanisms. However, it is unclear whether this conservation is reflected at the level of neural activity. Studies in humans have shown that anesthesia is characterized by spatially distinct spectral and coherence signatures that have also been implicated in the global impairment of cortical communication. We questioned whether anesthesia has similar effects on global and local neural processing in one of the smallest brains, that of the fruit fly (Drosophila melanogaster). Using a recently developed multielectrode technique, we recorded local field potentials from different areas of the fly brain simultaneously, while manipulating the concentration of isoflurane. Flickering visual stimuli ('frequency tags') allowed us to track evoked responses in the frequency domain and measure the effects of isoflurane throughout the brain. We found that isoflurane reduced power and coherence at the tagging frequency (13 or 17 Hz) in central brain regions. Unexpectedly, isoflurane increased power and coherence at twice the tag frequency (26 or 34 Hz) in the optic lobes of the fly, but only for specific stimulus configurations. By modeling the periodic responses, we show that the increase in power in peripheral areas can be attributed to local neuroanatomy. We further show that the effects on coherence can be explained by impacted signal-to-noise ratios. Together, our results show that general anesthesia has distinct local and global effects on neuronal processing in the fruit fly brain. PMID:27517084

    Full Text Available Introduction: Anxiety is a common disorder in patients before surgery. Inappropriately managed anxiety can cause psychological and physiological reactions and will affect the process of surgery and recovery. Therefore, this study examined the effects of hand mas-sage on anxiety in patients undergoing ophthalmology surgery using local anesthesia. Methods: In this interventional study, 52 patients who were supposed to undergo oph-thalmology surgery using local anesthesia were studied. Patients were randomly as-signed to two groups of intervention, who received hand massage before surgery (n = 27 and control (n = 25. Massaging lasted for 5 minutes (2.5 minutes on each hand before surgery. Stroking and scrubbing methods were performed by 2 trained research-ers. Anxiety level, blood pressure, heart rate, and respiratory rate were measured before and after the intervention in both groups. Anxiety was evaluated using Spielberger State-Trait Anxiety Inventory. Data was analyzed by chi-square, independent samples t-test, and paired t-test. Results: There were no significant differences in mean anxiety, systolic blood pressure, diastolic blood pressure, heart rate, and respiratory rate between the two groups before the intervention (p > 0.05. However, there was a significant differenc in the mean stress level between the two groups after the intervention (p 0.05. Conclusion: Our findings suggested that 5 minutes of hand massage before ophthalmology surgery (under local anesthesia could reduce anxiety. Therefore, this method can be used to increase patient comfort and reduce anxiety before surgical interventions.

    Full Text Available Opioids are central analgesics that act on the CNS (central nervous system and PNS (peripheral nervous system. We investigated the effects of codeine (COD and tramadol (TRAM on local anesthesia of the sciatic nerve. Eighty Wistar male rats received the following SC injections in the popliteal fossa: local anesthetic with epinephrine (LA; local anesthetic without vasoconstrictor (LA WV; COD; TRAM; LA + COD; LA + TRAM; COD 20 minutes prior to LA (COD 20' + LA or TRAM 20 minutes prior to LA (TRAM 20' + LA. As a nociceptive function, the blockade was considered the absence of a paw withdraw reflex. As a motor function, it was the absence of claudication. As a proprioceptive function, it was the absence of hopping and tactile responses. All data were compared using repeated-measures analysis of variance (ANOVA. Opioids showed a significant increase in the level of anesthesia, and the blockade duration of LA + COD was greater than that of the remaining groups (p < 0.05. The associated use of opioids improved anesthesia efficacy. This could lead to a new perspective in controlling dental pain.

    2015-01-01

    Full Text Available Aim: Pain is highly subjective and it is neurologically proven that stimulation of larger diameter fibers - e.g., using appropriate coldness, warmth, rubbing, pressure or vibration - can close the neural "gate" so that the central perception of itch and pain is reduced. This fact is based upon "gate control" theory of Melzack and Wall. The present study was carried out to investigate the effects of vibration stimuli on pain experienced during local anesthetic injections. Materials and Methods: Thirty patients aged 6-12 years old of both the genders with Frankel′s behavior rating scale as positive and definitely positive requiring bilateral local anesthesia injections for dental treatment were included in the split-mouth cross over design. Universal pain assessment tool was used to assess the pain with and without vibration during the administration of local anesthesia and the results obtained were tabulated and statistically analyzed. Results: Local anesthetic administration with vibration resulted in significantly less pain (P = 0.001 compared to the injections without the use of vibe. Conclusion: The results suggest that vibration can be used as an effective method to decrease pain during dental local anesthetic administration.

    Introduction Epinephrine containing local anesthetics are used hemostasis in many cases. Otolaryngologists typically selected to decrease bleeding in surgery field for operations such as especially FESS (Functional Endoscopic Sinus Surgery), septoplasty, septorhinoplasty. In addition to known adverse effects of this local anesthetics agents they have rare complications too. Presentation of case We presented intracranial hemorrhagic infarction in a 41-year-old male patient after using lidocaine with epinephrine for local anesthesia on nasal mucosa. Discussion There are some publications like this case in the literature. In our case, a hemorrhagic infarction developed after giving the adrenaline/lidocaine infiltration to make up a local anesthesia in the mucosa of the septum. There is not any reported case like this in the literature. Conclusion We want to emphasize that all surgeons especially the ENT surgeons should be careful while using local anesthetic medicines which contains adrenaline for rare complication of intracranial hemorrhagic infarction. Another fact is that the patients must sign an informed consent form including those situations even for all minor surgical procedures to avoid a medicolegal problem. PMID:26523877

    2011-06-01

    Tail docking of pigs is a routine procedure on farms to help control tail-biting behavior; however, docking can cause pain. The objective of this research was to evaluate the effect of local or general anesthesia on the physiology (experiment 1) and behavior (experiment 2) of tail docked pigs. Pigs were allocated to one of six treatment groups: (i) sham docking (CON); (ii) docking using conventional cutting (CUT) with side-cutting pliers; (iii) CUT docking plus local anesthesia injected immediately before docking (LA); (iv) CUT docking plus short-acting local anesthesia applied topically to the tail wound (SHORT); (v) CUT docking plus long-acting anesthesia applied topically to the tail wound (LONG) and (vi) CUT docking while the pig was anesthetized with carbon dioxide gas (CO(2)). In experiment 1, blood samples were collected from pigs (10 pigs per treatment) before and 30, 60 and 120 min after docking to measure leukocyte counts and percentages and cortisol concentrations. In experiment 2, the above treatments were repeated (10 pigs per treatment); the percentage of stress vocalizations were recorded during the administration of the treatments and behavior was recorded for up to 120 min after docking or handling. All pigs were weighed before and 24 h after docking and wound healing was recorded until weaning. The neutrophil/lymphocyte ratio was greater (P pigs. At 30 min, cortisol concentrations were greater (P pigs. Cortisol concentrations did not differ (P > 0.05) between SHORT and CON pigs 30 min after docking. Cortisol concentrations did not differ (P > 0.05) among pigs given pain relief at the time of docking compared with pigs' docked without pain relief. Body weight change and wound scores did not differ (P > 0.05) among treatments. The percentage of stress vocalizations increased (P pigs in response to docking or handling. The percentage of time pigs spent lying without contact after docking tended to be greater (P = 0.06) in CUT pigs compared with all

    Ambulatory hernia surgery under local anesthesia is becoming more widely used worldwide. Although many reports include obese patients, there are no studies that report specifically on the feasibility and safety of ambulatory hernia surgery in this category of patients. This paper documents our experience in this respect. The present investigation is an observational study performed at the CRS Hernia Center, Santiago, Chile, on 510 obese and 1,521 non-obese patients with all kinds of hernias susceptible to ambulatory hernia repair under local anesthesia. Both tissue and mesh repairs were performed. Obesity was defined as a body mass index (BMI) greater than 30. Patients with a BMI greater than 45 were excluded from this study. Operative time and pain experienced during the intervention were recorded. During the controls performed by a staff member at the 7th postoperative day, a questionnaire was answered by each patient regarding satisfaction, complaints, and postoperative pain. A second questionnaire was completed on the 30th postoperative day. Satisfaction and pain were both measured by means of a 10-point visual analog scale (VAS). The mean age was similar in both groups (51 years for non-obese and 52 years for obese patients). Obesity was present in 38.3% of women and in 17.5% of men (P ambulatory abdominal wall hernia repair under local anesthesia is feasible in obese patients. Because of the increased length of surgery in these patients, monitored sedation and prophylactic antibiotic cover should be used. The slight decrease in patient satisfaction is balanced by the lower risks and higher costs associated with full general anesthetic.

    The article presents the results of 42 video-abscessoscopies (VAS) in acute and gangrenous lung abscess and 32 video-thoracoscopies (VTS) in pyopneumothorax, which were performed using local anesthesia and sedation. There were several indication to operation: sanation of cavities, removal of necrotic sequestration and fibrin, decollement, biopsy. Perioperative complications developed after 11 surgeries (13%): emphysema of soft tissues of pectoral cells (5), phlegmon of the thorax (3), bronchial hemorrhage (2), pneumothorax (1). One of the patients died, because of progressing of main disease. VAS and VTS were carried out in 5-8 days after cavity drainage of abscess or pleural cavity in 50 patients.. In other 15 cases operations were performed directly before drainage. The bronchial hemorrhage and phlegmons of the thorax were noted in patients of second group. The patients had good tolerance of VAS and VTS operations fulfilled using local anesthesia and sedation. They are safe in case that operation follows drainage of abscess or pleural cavity after decrease of inflammatory processes. PMID:26390589

    The aim of this study was to evaluate a recently developed preclinical injection and cavity preparation model in local anesthesia. Thirty-three dental students administered an inferior alveolar nerve block injection in the model, followed by preparation on a tooth. The injection was evaluated by three observers, and the feedback from the model was registered. After completion of the practical session, the opinion of the dental students was explored with a ten-item questionnaire. Thirty dental students (91 percent) performed the injection correctly according to the feedback of the model, and twenty-eight students (85 percent) did so according to the expert opinion. The agreement between feedback from the training model and the expert opinion was high. The students were very satisfied with the opportunity to practice with the training model, as indicated by the high scores on each item of the questionnaire. These results suggest that use of this preclinical training model in anesthesia teaching may have beneficial effects on the administration of local anesthetics by dental students.

    Full Text Available Introduction. Tumescent local anesthesia (TLA is widely used for ambulatory surgery. Patients with transplanted organs are on immunosuppressive therapy and with risk for organ rejection or severe infection. Case report. Saphenectomy with phlebectomy on the left leg under TLA was performed in a patient with kidney transplantation performed four years ago. A combination of 35 mg of 1% prilocaine-hydrochloride, 5 mL of 8.4% sodium bicarbonate and 500 μg of epinephrine in 460 mL of normal saline was used for TLA. Overall 750 mL of the solution was used. The patient had satisfactory postoperative analgesia and was discharged home on the same day. Blood levels of urea, creatinine, estimated glomerular filtration rate (eGFR and tacrolimus concentration, measured preoperatively and on the second postoperative day, were in a regular range. Prilocaine blood concentrations determined on the 4th, 10th and 16th postoperative hours, were below toxic levels. Conclusion. TLA in a kidney-transplanted patient performed for saphenectomy with phlebectomy proved to be a safe and reliable anesthesia method.

    Anorectal procedures are often performed in an outpatient setting using a variety of anesthetic techniques. One technique that has not been well studied is surgeon-administered conscious sedation along with local anesthetic. The purpose of this study was to evaluate the use of this technique with emphasis on safety, efficacy, and patient satisfaction. Chart review was performed on 133 consecutive patients who had anorectal procedures at an outpatient surgery center. Additionally, 65 patients were enrolled prospectively and completed a satisfaction survey. Inclusively, charts of 198 patients who underwent outpatient anorectal surgery under conscious sedation and local anesthesia under the direction of a colorectal surgeon from 2004 through 2008 were reviewed. Parameters related to patient and procedural characteristics, safety, efficacy, and satisfaction were evaluated. Surgeon-administered sedation consisted of combined fentanyl and midazolam in 90 per cent. Eighty per cent of procedures were performed in the prone position and 23 per cent were in combination with an endoscopic procedure. Eighty-two per cent were classified as American Society of Anesthesiologists Grade 1 or 2. Transient mild hypoxemia or hypotension occurred in 4 and 3 per cent of the patients, respectively. Mean operative time was 29 minutes with a mean stay in the postanesthesia care unit of 37 minutes. There were no early major cardiac or respiratory complications. Ninety-seven per cent of the patients surveyed reported a high degree of satisfaction. Surgeon-administered conscious sedation with local anesthesia was well tolerated for outpatient anorectal surgeries. Additional studies are needed to confirm the safety and efficacy of this technique.

    This prospective randomized clinical crossover trial was designed to compare hypnosis and local anesthesia for experimental dental pain relief. Pain thresholds of the dental pulp were determined. A targeted standardized pain stimulus was applied and rated on the Visual Analogue Scale (0-10). The pain threshold was lower under hypnosis (58.3 ± 17.3, p < .001), maximal (80.0) under local anesthesia. The pain stimulus was scored higher under hypnosis (3.9 ± 3.8) than with local anesthesia (0.0, p < .001). Local anesthesia was superior to hypnosis and is a safe and effective method for pain relief in dentistry. Hypnosis seems to produce similar effects observed under sedation. It can be used in addition to local anesthesia and in individual cases as an alternative for pain control in dentistry. PMID:27585724

    The study evaluated duration and depth of the local infiltration anesthesia by articaine with different combinations of epinephrine and clonidine : articaine (4%) + epinephrine (1: 200 000), articaine (4%) + clonidine (1:100 000), articaine (4%) + epinephrine (1:200 000) + clonidine (1:100 000), articaine (4%) + epinephrine (1: 400 000) + clonidine (1:100, 000) in pediatric dental practice. It was revealed that the replacement of the vasoconstrictor epinephrine on clonidine associated with reduced depth and duration of analgesia. This increased efficiency is provided by inclusion of epinephrine (1:200 000), and clonidine (1:100 000) into anesthetic solution, which provided statistically significant increase in depth and duration of anesthesia.

    Published data suggest that the regional anesthetic technique used for carotid endarterectomy (CEA) increases the systolic arterial blood pressure and heart rate. At the same time local anesthesia reduced the shunt insertion rate. This study aimed to analyze risk factors and ischemic symptomatology in patients with postoperative internal carotid artery restenosis. The current retrospective study was undertaken to assess the results of CEA in 8000 patients who were operated during a five-year period in six regional cardiovascular centers. Carotid color coded flow imaging, medical history, clinical findings and atherosclerotic risk factors were analyzed. Among them, there were 33 patients (0.4%) with postoperative re-occlusion after CEA. The patients with restenosis were re-examined with carotid color coded flow imaging and data were compared with 33 consecutive patients with satisfactory postoperative findings to serve as a control group. In the restenosis group eight risk factors were analyzed (hypertension, smoking, hyperlipidemia, diabetes mellitus, history of stroke, transitory ischemic attack, heart attack and coronary disease), and compared with risk factors in control group. Study results suggested that early postoperative internal carotid artery restenosis was not caused by atherosclerosis risk factors but by intraoperative shunt usage. PMID:20439301

    From 1982 to 1986, 79 women with severe health problems underwent tubal occlusion by minilaparotomy using local anesthesia and intravenous sedation as a permanent method of fertility regulation. All the patients reported herein were classified as "high risk" population for a surgical procedure due to the following medical reasons: cardiovascular (30.2%); diabetes mellitus (25.3%); thyroid disease (18.9%); adrenal dysfunction (11.3%); kidney transplantation (6.3%); severe hypertension (3.7%); and pulmonary problems (3.7%). The procedure morbidity was 3.7% and the mortality 0%. The follow-up rate at 1 year was 86% and no pregnancies or complications of the primary disease due to the surgical procedure have been reported. It was concluded that tubal ligation by minilaparotomy performed by well-trained staff and with back-up hospital services on an out-patient basis is a safe and effective method of family planning in patients considered as a "high risk" population.

    To compare the effectiveness of 2 injection methods of lidocaine during a transrectal ultrasound (TRUS)-guided prostate biopsy for pain control and complication rates. We retrospectively evaluated patients who underwent a TRUS-guided prostate biopsy from March 2005 to March 2006. One hundred patients were categorized into two groups based on injection method. For group 1, 10 mL of 1% lidocaine was injected bilaterally at the junction of the seminal vesicle and prostate and for group 2, into Denonvilliers' fascia. Pain scores using a visual analog scale (VAS) as well as immediate and delayed complication rates were evaluated. The mean VAS score showed no significant differences between the groups (group 1, 3.4{+-}1.78: group 2, 2.8{+-}1.3: p = 0.062). The difference in delayed complication rates and incidence of hematuria, hemospermia, and blood via the rectum was not significant between groups. However, two patients in group 1 complained of symptoms immediately after local anesthesia: one of tinnitus and the other of mild dizziness. There were no significant differences between pain control and complication rates between the 2 lidocaine injection methods. However, injection into Denonvilliers' fascia is thought to have less potential risk

    The aim of the study was to evaluate the analgesic effect of lidocaine in a double-blind, controlled multi-center study on patients with atypical odontalgia (AO)--a possible orofacial neuropathic pain condition. Thirty-five consecutive AO patients (range 31-81 years) with a mean pain duration of 7.2 years (range 1-30 years) were recruited from four different orofacial pain clinics in Sweden. In a randomized cross-over design, 1.5 ml local anesthesia (20mg/ml lidocaine and 12.5 microg/ml adrenaline) or 1.5 ml saline (9 mg/ml NaCl solution) (placebo) was injected to block the painful area. The VAS pain scores showed an overall effect of time (ANOVA: P<0.001) and treatment (ANOVA: P=0.018) with a significant interaction between the factors (ANOVA: P<0.001). Overall, VAS pain relief was significantly greater at 15-120 min following the lidocaine injections compared to the placebo injections (Tukey: P<0.05). All patients demonstrated significant disturbances in somatosensory function on the painful side compared to the non-painful side as revealed by quantitative sensory tests, however, only one significant inverse correlation was found between percentage pain relief and the magnitude of brush-evoked allodynia (Spearman: P<0.01). In conclusion, AO patients experienced significant, but not complete, pain relief from administration of local anesthetics compared with placebo. The findings indicate that the spontaneous pain in AO patients only to some extent is dependent on peripheral afferent inputs and that sensitization of higher order neurons may be involved in the pathophysiology of AO.

It is shown that in terms of impact on the cardiovascular system and stress adaptation indicators anesthesia including combination of epinephrine (1: 200 000) and clonidine (1: 100 000) in the anesthetic solution is the safest. Furthermore, this method ensures the most appropriate analgesic effect.

    Objective: To observe the influence of local infiltration anesthesia at the scalp-point on acupuncture stimulation induced changes of cerebral blood perfusion in the brain. Methods: Experiments were conducted in 10 healthy volunteer subjects (8 males and 2 females) who were ordered to take a lying position on a specific bed with their heads keeping in a fixed position. Scalp-point used was Motor Area (MS 6). The first syringe needle (gauge-5) was inserted into the scalp from the upper 1/5 of MS-6 and the second syringe needle inserted into the scalp from the middle 2/5 of MS-6 and advanced downward, with the two needles connected to a HAN's Therapeutic Apparatus. Images of the brain were then taken before and after electroacupuncture (EA) stimulation, and after local injection of 1% lidocaine [mixed with epinephrine (1∶200,000, 3 mL)] plus EA by using Siemens ECAM/ICON Single Photo Emission Computed Tomography (SPECT). Intravenous injection of Ethyl cysteinate dimmer 555 MBq was performed before displaying cerebral images. Data of blood functional changing rat (BFCR%) were analyzed quantitatively using a mathematic model. Results: Before EA stimulation, the blood perfusion and function of cerebral cortex, thalamus, basal ganglion and cerebellum on both sides of the brain were basically symmetry. Following EA of MS-6, BFCR% of the contralateral thalamus, parietal lobe and the frontal lobe increased significantly. Following local infiltration anesthesia, BFCR% of the contralatral thalamus declined markedly (P<0.05). The results of quantitative analysis were in agreement with those of visual observation. Conclusion: Local infiltration anesthesia of the scalp-point can significantly weaken or block EA stimulation induced changes of BFCR%.

    Full Text Available The nerve supply of the human prostate is very abundant, and knowledge of the anatomy contributes to successful administration of local anesthesia. However, the exact anatomy of extrinsic neuronal cell bodies of the autonomic and sensory innervation of the prostate is not clear, except in other animals. Branches of pelvic ganglia composed of pelvic (parasympathetic and hypogastric (sympathetic nerves innervate the prostate. The autonomic nervous system plays an important role in the growth, maturation, and secretory function of this gland. Prostate procedures under local anesthesia, such as transurethral prostatic resections or transrectal ultrasound-guided prostatic biopsy, are safe, simple, and effective. Local anesthesia can be feasible for many special conditions including uncomplicated prostate surgery and may be particularly useful for the high-risk group of patients for whom inhalation or spinal anesthesia is inadvisable.A prostáta, uma das glândulas sexuais acessórias masculinas, possui inervação muito rica. A anatomia detalhada dos corpos neuronais extrínsecos responsáveis pela inervação autonômica e sensorial da próstata não está totalmente esclarecida, exceto em animais. A próstata é inervada pelos nervos pélvico (parassimpático e hipogástrico (simpático, ramos dos gânglios nervosos pélvicos. O sistema nervoso autonômico possui importante papel no crescimento, maturação e na função secretora desta glândula.

    Prolonged numbness following routine dental treatments can cause difficulties in speaking and swallowing and may result in inadvertent biting of soft tissues. Local injection of vasodilator agents may represent a solution to this problem. The aim of this study was to evaluate the effect of submucosal injection of hydralazine hydrochloride (HCl) on the duration of oral soft tissue anesthesia after routine dental treatment. This randomized, single-blinded, controlled clinical trial included 50 patients who received inferior alveolar nerve block (2% lidocaine with 1:100,000 epinephrine) for simple restorative treatment. Upon completion of the dental treatment, patients randomly received a hydralazine HCl or sham injection in the same site as the local anesthetic injection. The reversal time to normal sensation of soft tissues (lips, tongue, and perioral skin) was evaluated and reported every 5 minutes by the patients, who followed an assessment protocol that they were taught in advance of treatment. Median recovery times in the hydralazine group and the sham group were 81.4 (SD, 3.6) and 221.8 (SD, 6.3) minutes, respectively. Based on Kaplan-Meier survival analysis, the duration of soft tissue anesthesia in the 2 groups was significantly different (P < 0.0001). By 1 hour after the reversal injection, 76% of subjects receiving hydralazine HCl had returned to normal intraoral and perioral sensation, but none of the subjects in the sham group reported normal sensation. Based on these results, submucosal injection of hydralazine HCl can be considered a safe and effective method to reduce the duration of local anesthetic-induced soft tissue numbness and the related functional problems.

    Background. Given the influence of systemic blood pressure on pulpal blood flow, anxiolytics prescribed may alter the pulpal blood flow along with the local anesthetic solution containing a vasoconstrictor. This study evaluated the impact of preoperative anxiolytics and vasoconstrictors in local anesthetic agents on pulpal oxygen saturation. Methods. Thirty anxious young healthy individuals with a mean age of 24 years were randomly selected using the Corah’s Dental Anxiety Scale (DAS). After checking the vital signs the initial pulpal oxygen saturation (initial SpO2) was measured using a pulse oximeter. Oral midzolam was administered at a dose of 7.5 mg. After 30 min, the vital signs were monitored and the pulpal oxygen saturation (anxiolytic SpO2) was measured. A total of 1.5 mL of 2% lidocaine with 1:200000 epinephrine was administered as buccal infiltration anesthesia and 10 min the final pulpal oxygen saturation (L.A SpO2) was measured. Results. The mean initial (SpO2) was 96.37% which significantly decreased to 90.76% (SpO2) after the administration of the anxiolytic agent. This drop was later accentuated to 85.17% (SpO2) after administration of local anesthetic solution. Statistical significance was set at Pcavity preparation. Therefore, maintaining optimal blood flow during restorative procedures may prevent pulpal injury. PMID:27092212

    during or after dental treatment under anesthesia with vasoconstrictor (epinephrine. METHODS: A total of 54 coronary patients undergoing dental extraction under local anesthesia with or without vasoconstrictor were included. They were divided into two groups (by drawing envelopes: group I (27 patients using anesthetics with vasoconstrictor, and group II (27 cases without vasoconstrictor. 24-hour Holter monitoring, Doppler-echocardiogram before and after dental intervention, and determination of biochemical markers (CK-MB mass, CK-MB activity, and troponin T before and 24 hours after dental extraction were performed in all patients. Heart rate and blood pressure were also measured in the pre, post-anesthesia and post-dental extraction phases. Doppler echocardiography assessed left ventricular segmental contractility and the occasional occurrence of mitral regurgitation. The usual pharmaceutical treatment prescribed by the cardiologist was maintained in all cases. RESULTS: Three patients in group I presented ST-segment depression (1.0 mm during administration of anesthesia; two other patients in group I had CK-MB mass elevation, and ischemia was not observed in any other case, as assessed by the other methods. No chest pain, arrhythmias, occurrence or worsening of left ventricular segmental hypocontractility or mitral regurgitation were observed in the study. CONCLUSION: Dental extraction performed under anesthesia with 1:100,000 epinephrine does not imply additional ischemic risks, as long as performed with good anesthetic technique and maintenance of the pharmacological treatment prescribed by the cardiologist.

    Dental anxiety and fear of needle injection is one of the most common problems encountered by dental practitioners, especially in the pediatric patient. In consequences, it might affect the patient's quality of life. Several methods are suggested to lower the discomfort of local anesthesia injection during dental procedures. Desensitization of injection site is one of the recommended strategies. Among chemical anesthetic topical agents that are effective but might have allergic side effects, using some nonpharmacological and safe techniques might be useful. This study aimed to overview the efficacy of using cooling techniques, mostly by ice or popsicles, warming or pH buffering of drug, and using modern devices to diminish the discomfort of local anesthesia injection during dental procedures.

    Full Text Available Abstract Background Besides the amygdala, of which emotion roles have been intensively studied, the cerebellum has also been demonstrated to play a critical role in simple classical fear conditioning in both mammals and fishes. In the present study, we examined the effect of local administration of the anesthetic agent lidocaine into the cerebellum on fear-related, classical heart-rate conditioning in goldfish. Methods The effects of microinjection of the anesthetic agent lidocaine into the cerebellum on fear conditioning were investigated in goldfish. The fear conditioning paradigm was delayed classical conditioning with light as a conditioned stimulus and electric shock as an unconditioned stimulus; cardiac deceleration (bradycardia was the conditioned response. Results Injecting lidocaine into the cerebellum had no effect on the base heart rate, an arousal/orienting response to the novel stimulus (i.e., the first presentation of light, or an unconditioned response to electric shock. However, lidocaine injection greatly impaired acquisition of conditioned bradycardia. Lidocaine injection 60 min before the start of the conditioning procedure showed no effect on acquisition of conditioned bradycardia, indicating that the effect of lidocaine was reversible. Conclusions The present results further confirm the idea that the cerebellum in teleost fish, as in mammals, is critically involved in classical fear conditioning.

OBJECTIVES: Randomized clinical trial to compare the results from these two techniques. METHODS: Fifty patients were randomized for loop colostomy closure using spinal anesthesia (n = 25 and using local anesthesia (n = 25. Preoperatively, the bowel was evaluated by means of colonoscopy, and bowel preparation was performed with 10% oral mannitol solution and physiological saline solution for lavage through the distal colostomy orifice. All patients were given prophylactic antibiotics (cefoxitin. Pain, analgesia, reestablishment of peristaltism or peristalsis, diet reintroduction, length of hospitalization and rehospitalization were analyzed postoperatively. RESULTS: Surgery duration and local complications were greater in the spinal anesthesia group. Conversion to general anesthesia occurred only with spinal anesthesia. There was no difference in intraoperative pain between the groups, but postoperative pain, reestablishment of peristaltism or peristalsis, diet reintroduction and length of hospitalization were lower with local anesthesia. CONCLUSIONS: Local anesthesia plus sedation offers a safer and more effective method than spinal anesthesia for loop colostomy closure.CONTEXTO: Estudos recentes têm demonstrado que a anestesia local para o fechamento de colostomia em alça é tão segura quanto a raquianestesia para estes procedimentos.

    Background and Objectives adial artery spasm is one of the most common complications of transradial coronary angiography (TRA): the radial artery is prone to cathecholamine-induced contraction and radial pain during TRA could increase the sympathetic tone. The object of this study was to evaluate whether the eutectic mixture of local anesthesia (EMLA) cream, in addition to lidocaine infiltration, could reduce the sympathetic response by reducing radial pain during TRA. Subjects and Methods Seventy-six patients were randomized 1 : 1 to either EMLA or control groups. Radial pain was measured by the visual analogue scale (VAS) and the verbal rating scale (VRS-4). Sympathetic response, including systolic (SBP) and diastolic blood pressure (DBP), pulse rate (PR), stroke volume (SV) and total peripheral resistance (TPR), was measured by photoplethysmography. Results Radial pain measured during lidocaine infiltration was significantly lower in the EMLA group (VAS: 3.1 vs. 4.0, p=0.04; VRS-4: 2.0 vs. 2.2, p=0.03) and the sympathetic response was significantly blunted in the EMLA group from baseline to lidocaine infiltration (ΔSBP, mm Hg: 5 vs. 13, p<0.01; ΔDBP, mm Hg: 2 vs. 7, p=0.03; ΔPR, beat/min: 2 vs. 8, p<0.01, ΔSV, mL: 3 vs. 21, p<0.01; ΔTPR, mm Hg · L/min: 1.0 vs. 5.9, p<0.01). Conclusion In patients undergoing TRA, the EMLA cream, in addition to lidocaine infiltration, effectively reduces the radial pain and thereby the sympathetic response, during lidocaine infiltration.

    Because of its rapid onset time, recent years have seen an increase in the use of ultrasound (US)-guided popliteal sciatic nerve block (PSNB) via subparaneural injection for induction of surgical anesthesia. Moreover, in below-knee surgery, combined blocks, as opposed to sciatic nerve block alone, have become more common. These combined blocks often require a large volume of local anesthetic (LA), thus increasing the risk of local-anesthetic systemic toxicity (LAST). Thus, to decrease the risk of LAST, it is important to know the minimum effective volume (MEV) required for an adequate block. We, therefore, aimed to determine the MEV of ropivacaine 0.75% for induction of surgical anesthesia by the method of US-guided popliteal sciatic nerve block via subparaneural injection.Thirty patients underwent a US-guided PSNB with ropivacaine 0.75% at a 20-mL starting volume. Using a step-up/step-down method, we determined injection volumes for consecutive patients from the preceding patient's outcome. When an effective block was achieved within 40 minutes after injection, the next patient's volume was decreased by 2 mL. If the block failed, the next patient's volume was increased by 2 mL. The sensory and motor blockade was graded according to a 4-point scale. The block was considered a success if a combination of anesthesia and paresis (a score of 3 for both the sensory and motor nerves) was achieved within 40 minutes. The primary outcome measure was the MEV resulting in a successful subparaneural block of the sciatic nerve in 50% of patients (MEV50). Additionally, the data were processed with a probit regression analysis to determine the volume required to produce a complete sciatic nerve block in 90% of subjects (ED90).The MEV50 of 0.75% ropivacaine is 6.14 mL (95% confidence interval, 4.33-7.94 mL). The ED90 by probit analysis for a subparaneural injection was 8.9 mL (95% CI, 7.09-21.75 mL).The 6.14-mL MEV50 of ropivacaine 0.75% represents a 71% reduction

  16. Minimal-flow xenon and semiclosed circuit anesthesia for computed tomographic measurement of local cerebral blood flow (LCBF)

    International Nuclear Information System (INIS)

    For the purpose of decreasing the volume of expensive xenon, anesthesia with minimal-flow xenon and semiclosed circuit were induced for computed tomographic LCBF measurement. Eighteen patients with ischemic cerebral disease were studied. Xenon inhalation programs were subdivided into three groups, each of them consisted of 6 patients. The formula for calculating fresh gas flow for low flow semiclosed circuit was introduced according to Shimoji's which was based on the original formula of Foldes. O2 concentration in circuit was predicted to be 25%. Mean xenon uptake for initial 20 minutes was predicted to be125 ml/min. or 360 ml/min. The first group started xenon inhalation during pure xenon inflow into semic losed circuit for two minutes and followed by about 68% xenon in O2 inhalation for 23 munites. FXe and VXe were fixed at 700 ml/min and 360 ml/min respectively. The second group was set at the same conditions as the first group except FXe and VXe as shown in Fig.2. The third group inhaled about 63% xenon-oxygen mixture affer four minutes pure xenon inflow. Xenon concentrations in trachea, carotid artery and jugular vein were estimated from the conversion into equivalent enhancement in CT units for every four minutes on line. Fig. 3 shows the O2 concentration change in semiclosed circuit, endtidal CO2 tension and percent change of mean arterial pressure. After 20 minutes xenon inhalation O2 concentration in each group closed to 25% which was predicted O2 concentration of the third group closed more rapidly to 25% than other groups. Normocarbia and stable hemodynamics could be confirmed throughout the procedures in each group. Fig. 5 shows xenon washin curves in trachea and xenon concentration change in carotid artery and jugular vein during xenon inhalation. The washin curves in trachea are quite different in each group.

    Tracheal intubation general anesthesia technique is widely used in video-assisted thoracic surgery (VATS) because it can improve the safety of VATS, but the complications of tracheal intubation can not be avoided. How to develop a "minimally invasive" surgery (including micro anesthesia) has become a hot topic in the field of minimally invasive surgery. Along with the progress of the anesthesia management technology and the risk management in the operation, the technology of non-intubated anesthesia was successfully applied to VATS, namely using local anesthesia to maintain patients intraoperative independent ventilation and intraoperative only mild sedation or fully conscious state of implementation of thoracoscope surgery, therefore is also called awake VATS. The anesthesia method not only reduces the anesthesia injury of tracheal intubation, but also conforms to the idea of rapid rehabilitation surgery. Based on non-intubated anesthesia in VATS in the brief history of development, the anesthesia selection, operation advantages and risks are reviewed in this paper.

    2016-06-01

    The incidence of back pain after neuraxial anesthesia in the adult population is not different from that after general anesthesia. The pain is usually mild, localized in the low back, rarely radiates to the lower extremities, and has a duration of only a few days. The risk factors for development of back pain include the lithotomy position, multiple attempts at block placement, duration of surgery longer than 2.5 hours, body mass index ≥32 kg/m, and a history of back pain. However, there is no permanent worsening of preexisting back pain after neuraxial anesthesia. The back pain has been attributed to tears in the ligaments, fascia, or bone with localized bleeding; immobility of the spine; relaxation of the paraspinal muscles under anesthesia; flattening of the normal lumbar convexity; and stretching and straining of the lumbosacral ligaments and joint capsules. The addition of an anti-inflammatory drug to the local anesthetic used for skin infiltration may decrease the incidence and severity of back pain. The use of spinal or epidural anesthesia in the adult, non-obstetric and obstetric populations should depend on the advantages offered by the technique and not on the occurrence of back pain after the procedure. Additional studies are needed to confirm the efficacy of epidural dexamethasone, or other steroids, or the addition of an anti-inflammatory drug to the local anesthetic infiltration for the prevention of back pain after neuraxial anesthesia. Future studies should involve a physician with expertise in the evaluation of chronic low back pain to help identify the cause of the back pain and institute appropriate treatment(s). PMID:27195644

    To investigate the changes in respiratory function of COPD patients with osteoporotic vertebral compression fractures (OVCFs) after kyphoplasty (KP). Pain scores, pulmonary function parameters (PFT), and local kyphotic angle (LKA) were measured in 31 older patients (25 women, 6 men) with OVCFs before, 3 days after and 3 months after kyphoplasty. The preoperative and postoperative (3 days, 3 months) PFT parameters were as follows: % pred FVC, 74.33 ± 12.35, 85.23.8 ± 13.23, and 84.86 ± 14.01; % pred FEV1, 60.23 ± 11.2, 60.02 ± 11.90, and 60.78 ± 12.70; FEV1/FVC ratio (%), 68.22 ± 16.74, 59.56 ± 13.23, and 60.77 ± 12.28, % pred MVV 52.46 ± 14.37, 55.23 ± 15.68, and 62.12 ± 14.48, respectively. The preoperative mean VAS score was 8.01 ± 1.41 and significantly decreased to 2.52 ± 0.89 and 2.34 ± 0.78 at 3 days, 3 months after kyphoplasty, respectively. The preoperative local kyphotic angle degree was 21.96 ± 5.75°, significantly decreased to 13.48 ± 6.12° 3 days after KP, and maintained 3 month after KP. The decrease in the VAS scores correlated with the PFT parameters; however, there were no significant correlations between the PFT parameters and the LKA, the VAS scores and the LKA. Kyphoplasty under local anesthesia is a safety treatment for the COPD patients with OVCFS, and is able to improve the lung function impaired by OVCFs.

    Full Text Available Background: During Middle Ear Surgeries (MES done under Local Anesthesia (LA, patients may feel discomfort due to noise of suction, manipulation of instruments, positioning of head-neck and sometimes due to pain. A bloodless microscopic field is also essential to facilitate surgical exposure in MES. Various combinations of analgesics and sedatives have been tried to alleviate apprehension of the patients and improve microscopic field which may result into reduction in surgical time. In the present study, we have compared Dexmedetomedine (Dex with Midazolam-Fentanyl (MF and PentazocinePromethazine (PP combinations for their sedoanalgesia, anxiolysis and other pharmacological effects when administered during MES, not lasting for more than 60 min. Material and Methods: Ninety American Society of American Society of Anesthesiologists (ASA group I /II patients admitted in either of the three hospitals during May 2014 to January 2015 for MES under LA were randomly divided into three groups by an independent observer. Group D received intravenous bolus of Injection Dexmedetomidine 1 µg/ kg over 10 min. Group MF received Injection Midazolam 0.06 mg/ kg + Inj. Fentanyl 1 µg/ kg and Group PP received Injection Pentazocine 0.3 mg/kg + Injection Promethazine 0.5mg/kg given intravenously followed by LA before taking incision for the surgery. Need of a rescue sedoanalgesic dose of (Midazolam 0.01 mg/kg + Fentanyl 0.5 µg/kg during the surgery was noted. All the patients received 500 ml of normal saline infusion till the end of the surgery. All surgeries were finished within 60 min. Vital parameters and Ramsay Sedation Score (RSS of the patients were noted from the time of administration of sedative till the end of the surgery. Patient and surgeon satisfaction scores were recorded immediately after the surgery.

    Pain control during the dental procedure is essentials and challenging. A complete efficacious pulp anesthesia has not been attained yet. The regional anesthesia such as inferior alveolar nerve block (IANB) only does not guarantee the effective anesthesia with patients suffering from irreversible pulpitis. This main aim of this review was to discuss various aspects of intraseptal dental anesthesia and its role significance in pain-free treatment in the dental office. In addition, reasons of failure and limitations of this technique have been highlighted. Literature search was conducted for peer-reviewed articles published in English language in last 30 years. Search words such as dental anesthesia, pain control, intraseptal, and nerve block were entered using a web of knowledge and Google scholar databases. Various dental local anesthesia techniques were reviewed. A combination of block anesthesia, buccal infiltration and intraligamentary injection resulted in deep anesthesia (P = 0.003), and higher success rate compared to IANB. For pain-free management of conditions such as irreversible pulpitis, buccal infiltration (4% articaine), and intraosseous injection (2% lidocaine) are better than intraligamentary and IANB injections. Similarly, nerve block is not always effective for pain-free root canal treatment hence, needing supplemental anesthesia. Intraseptal anesthesia is an efficient and effective technique that can be used in maxillary and mandibular adult dentition. This technique is also beneficial when used in conjunction to the regional block or local dental anesthesia. PMID:26955316

    The first ether anesthetic was administered in Germany by J.F. Heyfelder (1798-1869) at the Erlangen University Hospital on January 24, 1847. Thereafter, famous discoveries occurred in the field of pharmacology. Albert Niemann isolated cocaine from the coca shrub in 1860; Emil Fischer synthesized the first barbiturate, Veronal, in 1902; and Helmut Weese promoted the first ultra-short-acting barbiturate, hexobarbital (Evipan), in 1932. The local anesthetic effect of cocaine was reported by Koller at the Congress of the German Society for Ophthalmology on September 15, 1884, in Heidelberg. Many new techniques were tried first in German hospitals. Friedrich Trendelenburg carried out, by tracheotomy, the first operation with endotracheal intubation in 1869, and Franz Kuhn promoted and clinically practiced endotracheal intubation in Heidelberg beginning in 1900. August Bier performed the first operation under spinal anesthesia at the Kiel University Hospital on August 16, 1898. Carl Ludwig Schleich (1859-1922) standardized the methods of infiltration anesthesia by using a cocaine solution in sufficient dilution. The development of anesthesia machines was greatly influenced by Heinrich Dräger (1847-1917) and his son Bernhard Dräger (1870-1928). The Dräger Company in Lübeck built the first anesthesia machine with a carbon dioxide (CO2) absorber and circle system in 1925. Paul Sudeck and Helmut Schmidt worked with this system at the Hamburg University Hospital and reported their results in 1926. The first Dräger anesthesia machine was produced in 1902 and introduced into clinical use by Otto Roth (1863-1944) in Lübeck. Before the Second World War, three universities in Germany carried out research in the field of anesthesia: the University of Freiburg with H. Killian, the University of Hamburg with P. Sudeck and H. Schmidt, and the University of Würzburg with C.G. Gauss. Killian and Gauss established the first journals, Der Schmerz and Narkose und Anaesthesie, in

    Full Text Available Introduction. Anesthesia management is characterized by salary limiting and pressure for decreasing anesthetics and other drug budget. The aim of this paper is to determine the possibility of reducing the direct costs in anesthesia. Materials and methods. This paper is a part of a five-year (2005-2009, academic, pharmaco-economic retrospective- prospective study (phase IV. The study was done according to European Union Directive for Clinical Research. We retrospectively calculated and analyzed all anesthesia direct costs (personnel costs, anesthetics and other drug costs, materials, laboratory analyses, and machines at the Institute For Ane- sthesia and Reanimation, Clinical Center of Serbia in relation to the costs refunded by National Health Insurance in all patients who underwent anesthesia in 2006. Results. Out of 70 195 anesthesia services rendered to 32 267 patients in one-year period, 47% were general anesthesia, 23% were local anesthesia, and 30% were anesthetic procedures. Our results of highly significant association between personnel costs (r = 0.980, p = 0.000 and consumption of anesthetics and drugs (r = 0.885, p = 0.000 with the direct costs do not provide an opportunity for further cost reduction due to disassociation of direct costs and the ”unit price” of National Health Insurance issued in terms of the restricted maximum budget for health. Conclusion. There is no space for direct cost reduction in anesthesia.

    Full Text Available Introduction: We have analyzed our initial results of our anesthesia techniques in our new-onset endovascular aortic reconstruction cases.Patients and Methods: The perioperative data of 15 elective and emergent endovascular aortic reconstruction cases that were operated in 2010-2011 were collected in a database. The choice of anesthesia was made by the risk factors, surgical team’s preferences, type and location of the aortic pathology and by the predicted operation duration. The data of local and general anesthesia cases were compared.Results: Thirteen (86.7% cases were male and 2 (13.3% female. Eleven patients were in ASA Class III. The demographic parameters, ASA classifications, concurrent diseases were similar in both groups. Thirteen (86.7% cases had infrarenal abdominal aortic aneurysm and 2 (13.3% had Type III aortic dissection. The diastolic arterial pressures were lower in general anesthesia group in 20th and 40th minutes’ measurements just like the mean arterial pressure measurements at the 40th, 100th minutes and during the deployment of the graft. Postoperative mortality occurred in 3 (20.0% patients and they all had general anesthesia and they were operated on emergency basis. Postoperative morbidity occurred in four patients that had general anesthesia (acute renal failure, multi-organ failure and pneumonia. The other patient had atrial fibrillation on the 1st postoperative day and was converted to sinus rhythm with amiodarone infusion.Conclusion: Edovascular aortic reconstruction procedures can safely be performed with both general and local anesthesia less invasively compared to open surgery. General anesthesia may be preferred for the better hemodynamic control.

    The specific problems of outpatient anesthesia are discussed with respect to the patient's condition, the anesthesist's qualification and pharmacological properties of anesthetics used. Methohexitone seems to be the best choice for induction. Problems may arise from the use of Propanidid, Ketamin and Diazepam. Nitrousoxide and Enflurane are a suitable completion. Endotracheal intubation, if needed, is facilitated by Suxamethonium, which is rapidly eliminated. Practical aspects of timing, premedication, induction, maintenance and ending of anesthesia are pointed out. After 1-2 hours the patient can be allowed to leave the hospital accompanied by a responsible person. Driving a car is not recommended before 24 hours have elapsed since anesthesia.

    Full Text Available Tracheal intubation general anesthesia technique is widely used in video-assisted thoracic surgery (VATS because it can improve the safety of VATS, but the complications of tracheal intubation can not be avoided. How to develop a "minimally invasive" surgery (including micro anesthesia has become a hot topic in the field of minimally invasive surgery. Along with the progress of the anesthesia management technology and the risk management in the operation, the technology of non-intubated anesthesia was successfully applied to VATS, namely using local anesthesia to maintain patients intraoperative independent ventilation and intraoperative only mild sedation or fully conscious state of implementation of thoracoscope surgery, therefore is also called awake VATS. The anesthesia method not only reduces the anesthesia injury of tracheal intubation, but also conforms to the idea of rapid rehabilitation surgery. Based on non-intubated anesthesia in VATS in the brief history of development, the anesthesia selection, operation advantages and risks are reviewed in this paper.

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

    Full Text Available Objective: to evaluate the nature of unilateral spinal anesthesia using various modes of administration of low doses of hyperbaric bupivacaine. Materials and Methods. Prospectively, the randomized study included 56 patients undergoing knee arthroscopy. In the control group bupivacaine of 5mg was administered simultaneously, in the main group — fractionally by 2.5 mg. The development of thermal and pain blocks from different sides was investigated. The data were statistically processed. Results. In the control group, the positioning of the patient usually began after the entire dose of anesthetic had been administered. In the case of temperature paresthesia in the area of the sacral segments of the full anesthesia throughout underlying limb was not always achieved. In 6 cases of block was not sufficient. In the main group patient positioning was performed after the administration of 2.5 mg of anesthetic and evaluate temperature paresthesia and in 2 cases the total dose was increased to 7.5 mg. The successful development of sensory block at fractional administration was significantly higher than in the single-step introduction. Conclusion. Temperature paresthesia occurs within the first minute and is an early predictor of developing spinal anesthesia. The area of arising paresthesia shows preferential distribution of the anesthetic. In the application of low dose local anesthetic the desired upper level of anesthesia via the patient positioning and dose adjustment may be achieved.

    venous stasis. In another experimental series the effect of general pentobarbital anesthesia on the vasoconstrictor activity in response to venous stasis locally in subcutaneous and muscle tissue in the hind limb was examined in 6 dogs. It was found that during the first 2-3 h of anesthesia...... the vasoconstrictor response was present in both tissues although the response in muscle tissue exhibited a great variation between the dogs during this period. However, after 4-5 h of anesthesia the response was abolished in both tissues. During neurolept anesthesia with fentanyl/N2O the same vasoconstrictor...... response was demonstrated in the hindleg 1 h and 5 h after induction of the anesthesia. It is concluded that pentobarbital anesthesia abolishes the arteriolar constriction induced by venous stasis. The mechanism may be blockade of the local sympathetic vasoconstrictor fibres or interference with myogenic...

    2008-05-01

    A strong tendency toward body enhancement and body forming in western industrial societies makes it more likely for each anesthesiologist to get involved in the care of bodybuilders. These patients quite frequently consume androgenic anabolic steroids, human growth hormone and other drugs or substances which are believed to accelerate muscle gain. Cardiovascular, hepatic, psychiatric, hormonal and infectious side effects or complications are common and rarely monitored by health care professionals. The anesthesia risk is not exactly known but seems to be determined mainly by cardiovascular events like myocardial ischemia and dysrhythmias.

    2007-01-01

    Full Text Available Anesthesia for thoracoscopy is based on one lung ventilation. Lung separators in the airway are essential tools. An anatomical shunt as a result of the continued perfusion of a non-ventilated lung is the principal intraoperative concern. The combination of equipment, technique and process increase risks of hypoxia and dynamic hyperinflation, in turn, potential factors in the development of an unusual form of pulmonary edema. Analgesia management is modelled on that shown effective and therapeutic for thoracotomy. Perioperative management needs to reflect the concern for these complex, and complicating, processes to the morbidity of thoracoscopic surgery.

This report reviews the perioperative course of patients with uncorrected cor triatriatum (CT undergoing procedures requiring anesthesia. In addition, we performed a literature search that examines the experience of others regarding the peri-operative course of patients with CT. Materials and Methods: A computerized search of a medical record database was conducted to identify patients with a clinical diagnosis of uncorrected CTD and CTS undergoing surgical procedures. Descriptive statistics were used. Results: We identified 12 adult patients with asymptomatic CTS (n = 7 and CTD (n = 5 who underwent 23 anesthetics. There were no perioperative complications which could be attributed directly to the anatomy of CT. Conclusions: Our observation and review of the literature suggest that patients with asymptomatic CT typically tolerate anesthesia and surgical procedures well.

    Directory of Open Access Journals (Sweden)

    Rochana Girish Bakhshi

    2011-11-01

    Full Text Available Achondroplasia is the commonest form of short-limbed dwarfism and occurs in 1:26,000- 40,000 live births. This is an autosomal dominant disorder with abnormal endochondral ossification whereas periosteal and intramembranous ossification are normal. The basic abnormality is a disturbance of cartilage formation mainly at the epiphyseal growth plates and at the base of the skull. The anesthetic management of achondroplastic dwarfs is a challenge to the anesthesiologist. Both regional as well as general anesthesia have their individual risks and consequences. We report a case of an achondroplastic dwarf in whom combined spinal epidural anesthesia was used for fixation of a fractured femur. The patient had undergone previous femur surgery under general anesthesia since he had been informed that spinal anesthesia could be very problematic. There was no technical difficulty encountered during the procedure and an adequate level was achieved with low-dose local anesthetics without any problem. Postoperative pain relief was offered for three consecutive postoperative days using epidural tramadol. We discuss the anesthetic issues and highlight the role of combined spinal epidural anesthesia with low-dose local anesthetics in this patient. This approach also helped in early ambulation and postoperative pain relief.

  20. Transverse myelitis following spinal anesthesia

    2006-01-01

    Full Text Available Spinal anesthesia is widely used during surgical procedures. It is generally safe and the frequency of severe, permanent neurological complications associated with it has been reported to be extremely low. We report a patient, who developed paraplegia following spinal anesthesia. A 29-year-old male was referred with acute, flaccid, sensory motor paraplegia, with bladder and bowel involvement. He developed this immediately after an operation for inguinal hernia under spinal anesthesia. Spinal magnetic resonance imaging revealed hemorrhagic myelitis in the conus at D12. He was referred after he did not respond to intravenous methylprednisolone for 10 days. This case brings up the difficulty encountered in determination of the interspace used for spinal anesthesia and the potential for traumatic injury to the spinal cord. It also demonstrates the tragic outcome after a clinician violates some important, standard and established guidelines.

    2016-08-01

    With anesthesia awareness as a model of study we debate the both fascinating and dangerous phenomenon called consciousness fluctuation that takes place during surgical anesthesia. In accordance with current scientific knowledge this paradox is the consequence of our limits in both precise knowledge of anesthesia mechanisms and our inability to accurately assess the level of anesthesia with brain monitoring. We also focus on the relationships between memory and anesthesia, as well as the possibility of interfering with memory during general anesthesia. PMID:27046232

    1989-01-01

    Experience obtained from adenotomy (AT) under general anesthesia using Ketamin hydrochloride (Ketalar, Narkamon) in children are presented in this paper. The authors had used intramuscular premedication with Prothazin, Dolsin and Atropin at the first stage, then they shifted to oral administration of a combination of Diazepam, Theadryl and Atropin. Ketamin may be applied intravenously in the dosage of 1.0 to 1.5 mg/kg of body weight in most children. Where it is not possible, a triple dose into the muscle is used. A total of 2,266 AT were performed. About 70% of patients were calm during the operation, once a suspected aspiration was considered but it was not confirmed. The main contribution of the method is 100% amnesia of the surgery made. The procedure is a compromise between a requirement for minimal traumatization of the child's psyche by the intervention and the resources available, particularly the need of personnel at the majority of otorhinolaryngo-logical departments nowadays.

    Full Text Available Ainda não esta comprovada a eficácia dos derivados morfínicos ao nível de receptores opióides periféricos. Estudos procuram demonstrar o poder da droga em interferir na intensidade da dor quando infiltrada em nervos periféricos. Avaliamos, então, a infiltração local de morfina associada à anestesia local em cirurgias orificiais proctológicas. Nesse estudo foram analisados 61 pacientes, independentemente do gênero, sendo divididos aleatoriamente em dois grupos: a um grupo foi associada morfina ao anestésico local enquanto ao outro houve a administração do anestésico local sem a droga morfínica. Os pacientes de ambos os grupos foram submetidos à sedação e analgesia pós-operatória padronizadas. Foram avaliados: a intensidade da dor, a analgesia pós-operatória e a morbidade. A intensidade da dor, no momento de seu surgimento, foi semelhante nos dois grupos; o tempo de analgesia pós-operatória foi maior no grupo em que a morfina foi administrada, entretanto, não se mostrou estatisticamente significativo; as complicações pós-operatórias foram irrelevantes nos dois grupos. Dessa forma, a infiltração local de morfina na região anorretal tem benefícios em relação à analgesia pós-operatória que não mostraram significância estatística e não aumenta a incidência dos efeitos colaterais tão temidos relacionados às drogas morfínicas como retenção urinária e prurido.It has not been proved the efficacy of morphine derived at periphery opium receivers.

    Diverse molecules induce general anesthesia with potency strongly correlated both with their hydrophobicity and their effects on certain ion channels. We recently observed that several anesthetics inhibit heterogeneity in plasma membrane derived vesicles by lowering the critical temperature ($T_c$) for phase separation. Here we exploit conditions that stabilize membrane heterogeneity to test the correlation between the anesthetic potency of n-alcohols and effects on $T_c$. First we show that hexadecanol acts oppositely to anesthetics on membrane mixing and antagonizes ethanol induced anesthesia in a tadpole behavioral assay. Second, we show that two previously described `intoxication reversers' raise $T_c$ in vesicles and counter ethanol's effects in vesicles, mimicking the findings of previous electrophysiological measurements. Third, we find that hydrostatic pressure, long known to reverse anesthesia, also raises $T_c$ in vesicles with a magnitude that counters the effect of an anesthetic at relevant concen...

    Rigid bronchoscopy under general anesthesia enables performing diagnostic and/or therapeutic procedures in the tracheobronchial tree. This technique is characterized by specific technical problems, insofar as the anesthesiologist and the operators share the same space, namely the airway. Several potential complications (hemorrhage inside the airway, threat to ventilation ...) may arise. These challenges render the ability to use the variable available techniques essential, as well as knowledge of the complications they could entail, and the ability to rapidly solve them. General anesthesia is usually total intravenous anesthesia, using short acting agents. Ventilation can be spontaneous, but more often insured using high-frequency jet ventilation. The hospital infrastructure and staff must have the expertise to perform this particular procedure, in order to limit the complication rate. PMID:25508517

    Full Text Available Objective: Entropy algorithms have been widely used in analyzing EEG signals during anesthesia. However, a systematic comparison of these entropy algorithms in assessing anesthesia drugs’ effect is lacking. In this study, we compare the capability of twelve entropy indices for monitoring depth of anesthesia (DoA and detecting the burst suppression pattern (BSP, in anesthesia induced by GA-BAergic agents.Methods: Twelve indices were investigated, namely Response Entropy (RE and State entropy (SE, three wavelet entropy (WE measures (Shannon WE (SWE, Tsallis WE (TWE and Renyi WE (RWE, Hilbert-Huang spectral entropy (HHSE, approximate entropy (ApEn, sample entropy (SampEn, Fuzzy entropy, and three permutation entropy (PE measures (Shannon PE (SPE, Tsallis PE (TPE and Renyi PE (RPE. Two EEG data sets from sevoflurane-induced and isoflu-rane-induced anesthesia respectively were selected to assess the capability of each entropy index in DoA monitoring and BSP detection. To validate the effectiveness of these entropy algorithms, phar-macokinetic / pharmacodynamic (PK/PD modeling and prediction probability analysis were applied. The multifractal detrended fluctuation analysis (MDFA as a non-entropy measure was compared.Results: All the entropy and MDFA indices could track the changes in EEG pattern during different anesthesia states. Three PE measures outperformed the other entropy indices, with less baseline vari-ability, higher coefficient of determination and prediction probability, and RPE performed best; ApEn and SampEn discriminated BSP best. Additionally, these entropy measures showed an ad-vantage in computation efficiency compared with MDFA.Conclusion: Each entropy index has its advantages and disadvantages in estimating DoA. Overall, it is suggested that the RPE index was a superior measure.Significance: Investigating the advantages and disadvantages of these entropy indices could help improve current clinical indices for monitoring DoA.

    Full Text Available Daniela Ghisi, Stefano Bonarelli Department of Anaesthesia and Postoperative Intensive Care, Istituto Ortopedico Rizzoli, Bologna, Italy Abstract: Spinal anesthesia is a reliable and safe technique for procedures of the lower extremities. Nevertheless, some of its characteristics may limit its use for ambulatory surgery, including delayed ambulation, risk of urinary retention, and pain after block regression. The current availability of short-acting local anesthetics has renewed interest for this technique also in the context of short- and ultra-short procedures. Chloroprocaine (CP is an amino-ester local anesthetic with a very short half-life. It was introduced and has been successfully used for spinal anesthesia since 1952. Sodium bisulfite was then added as a preservative after 1956. The drug was then abandoned in the 1980s for several reports of neurological deficits in patients receiving accidentally high doses of intrathecal CP during epidural labor analgesia. Animal studies have proven the safety of the preservative-free formulation, which has been extensively evaluated in volunteer studies as well as in clinical practice with a favorable profile in terms of both safety and efficacy. In comparison with bupivacaine, 2-chloroprocaine (2-CP showed faster offset times to end of anesthesia, unassisted ambulation, and discharge from hospital. These findings suggests that 2-CP may be a suitable alternative to low doses of long-acting local anesthetics in ambulatory surgery. Its safety profile also suggests that 2-CP could be a valid substitute for intrathecal short- and intermediate-acting local anesthetics, such as lidocaine and mepivacaine – often causes of transient neurological symptoms. In this context, literature suggests a dose ranging between 30 and 60 mg of 2-CP for procedures lasting 60 minutes or less, while 10 mg is considered the no-effect dose. The present review describes recent evidence about 2-CP as an anesthetic agent for

    2006-01-01

    It is known that the action of general anesthetics is proportional to their partition coefficient in lipid membranes (Meyer-Overton rule). This solubility is, however, directly related to the depression of the temperature of the melting transition found close to body temperature in biomembranes. We propose a thermodynamic extension of the Meyer-Overton rule which is based on free energy changes in the system and thus automatically incorporates the effects of melting point depression. This model provides a quantitative explanation of the pressure reversal of anesthesia. Further, it explains why inflammation and the addition of divalent cations reduce the effectiveness of anesthesia.

    2012-01-01

    Full Text Available The popularity of day case surgical procedures has increased immensely over the last few years. Though various techniques are available for carrying out day-case anesthesia, preference for a technique depends upon the type of procedure, patient profile, associated co-morbidities, available infrastructure and back-up facilities, monitoring devices and comfort of the attending anesthesiologist with the technique. Day-case spinal anesthesia for ambulatory surgery has gained a wider acceptance and numerous drugs are available for use in loco-regional anesthesia. Articaine is one such amide local anesthetic drug which is increasingly being used in day care surgeries. Properties of articaine such as faster onset, shorter elimination time and rapid recovery from sensory and motor blockade make it a very useful agent in local and regional anesthesia for day care surgical procedures. This article aims to review these properties of articaine so as to evaluate how useful articaine can be for ambulatory surgical procedures.

    Safe and effective anesthesia of dogs and cats rely on preanesthetic patient assessment and preparation. Patients should be premedicated with drugs that provide sedation and analgesia prior to anesthetic induction with drugs that allow endotracheal intubation. Maintenance is typically with a volatile anesthetic such as isoflurane or sevoflurane delivered via an endotracheal tube. In addition, local anesthetic nerve blocks; epidural administration of opioids; and constant rate infusions of lidocaine, ketamine, and opioids are useful to enhance analgesia. Cardiovascular, respiratory, and central nervous system functions are continuously monitored so that anesthetic depth can be modified as needed. Emergency drugs and equipment, as well as an action plan for their use, should be available throughout the perianesthetic period. Additionally, intravenous access and crystalloid or colloids are administered to maintain circulating blood volume. Someone trained in the detection of recovery abnormalities should monitor patients throughout recovery. Postoperatively attention is given to body temperature, level of sedation, and appropriate analgesia. PMID:22058343

    Anaphylaxis during anesthesia is uncommon. Diagnosis of peri-anesthesia anaphylaxis (PAA) requires anesthesia providers' vigilance for prompt diagnosis and treatment. In this case report, we present a challenging case with suspected PAA including its perioperative management, intensive care unit (ICU) course, and post-discharge follow-up. A 44-year-old female (body mass index = 26) presented for elective abdominal panniculectomy. Post-intubation, severe bronchospasm occurred that was non-responsive to nebulized albuterol and intravenous epinephrine. Continuous infusion of epinephrine was initiated. After aborting surgical procedure, the patient was transferred to ICU on continuous intravenous infusion of epinephrine. Venous blood sampling showed elevated troponin level. Echocardiography revealed ejection fraction of 25% suspicious of Takotsubo cardiomyopathy (mid cavitary variant). Tracheal extubation was only possible after three days. Subsequently, patient was discharged home with a cardiology follow-up appointment and a referral to an allergy specialist. Unfortunately at our institution (an academic university hospital in United States) along with neighboring institutions in near-by areas, the only allergy skin tests available are for local anesthetics and antibiotics, while neuromuscular blocking agents (NMBAs) cannot be tested (the suspected anaphylactic agent in our case was presumably rocuronium). In summary, PAA requires and responds to emergent diagnosis and immediate treatment; however there is still a long way to go to ensure post-PAA testing for inciting anesthesia-related allergens.

    General anesthesia in ophthalmological surgery has become a great fashion. However there are still many problems especially in intraocular surgery. The eye with normal intraocular pressure generally needs no special technique. Most of the usual anesthesia produce a slight hypotonia with the exception of Succinylcholine, whose effect is contrary. Unfortunately this is not the case in eyes with pathologically increased intraocular pressure as in the different forms of glaucoma. Eye surgeons and anesthesists therefore look for solutions to this problem which in principle consist in the application of medicaments, which not seldom are rather agressive. The controlled hypotension by ganglion blockers, the curarisation in the state of being awake, the rapid perfusion of solutions with high osmotique effect (isolated or associated) represent such measures. The one has the disadvantage to be applied during so-called subvigile anesthesias where the security that the patient is asleep is rather doubtful; the other has the disadvantage that it requires a rapid perfusion of solutions with highly osmotic effect. It goes without saying that these conditions represent risks especially if one considers that the candidates for this type of intervention very often are senile persons with prearious cardiovascular equilibrium, with insufficient renal function and with insufficient arterial cerebral circulation. These are some of the problems which are to be discussed.

  15. A psychoeducational intervention reduces the need for anesthesia during radiotherapy for young childhood cancer patients

    International Nuclear Information System (INIS)

    Radiotherapy (RT) has become an important treatment modality in pediatric oncology, but its delivery to young children with cancer is challenging and general anesthesia is often needed. To evaluate whether a psychoeducational intervention might reduce the need for anesthesia, 223 consecutive pediatric cancer patients receiving 4141 RT fractions during 244 RT courses between February 1989 and January 2006 were studied. Whereas in 154 RT courses corresponding with 2580 RT fractions patients received no psychoeducational intervention (group A), 90 RT courses respectively 1561 RT fractions were accomplished by using psychoeducational intervention (group B). This tailored psychoeducational intervention in group B included a play program and interactive support by a trained nurse according to age to get familiar with staff, equipment and procedure of radiotherapy. Group A did not differ significantly from group B in age at RT, gender, diagnosis, localization of RT and positioning during RT. Whereas 33 (21.4%) patients in group A got anesthesia, only 8 (8.9%) patients in group B needed anesthesia. The median age of cooperating patients without anesthesia decreased from 3.2 to 2.7 years. In both uni- and multivariate analyses the psychoeducational intervention significantly and independently reduced the need for anesthesia. We conclude that a specifically tailored psychoeducational intervention is able to reduce the need for anesthesia in children undergoing RT for cancer. This results in lower costs and increased cooperation during RT

  17. Pain management and regional anesthesia for the dental patient.

    Woodward, Tony M

    2008-05-01

    Current standards of care in veterinary medicine dictate an adequate level of pain control for our patients. Effective pain control uses a proactive, multimode approach that starts with preoperative medications, includes the anesthetic protocol selected, and continues into the postoperative period. A basic understanding of the physiology of pain assists in selecting those agents and modalities best suited for individual patients. Analgesic drug selection and local anesthesia are both integral parts of pain control when performing surgery in the oral cavity. Local (regional) anesthesia plays an important part in the pain control of oral surgical patients. Regional anesthetic techniques are used for many common oral procedures, including extractions, periodontal flap surgery, treatment of traumatic injuries of the oral cavity, tumor removal, palatal surgery, periodontal therapy, and root canal therapy. This presentation will cover strategies for analgesia and the techniques and materials used in local/regional anesthesia in the oral cavity. Anatomic landmarks and guidelines for effective regional blocks will be covered. PMID:18482711

    This study was undertaken to compare the anesthetic properties of articaine hydrochloride with 1:200,000 epinephrine (Ultracain DS) and lidocaine with 1:80,000 epinephrine (Xylocain-Adrenalin) for maxillary infiltration anesthesia. Twenty healthy dental student volunteers were included in this double-blind study. Each subject received 0.6 mL of each test solution at different times. Infiltration anesthesia was performed on the upper lateral incisor. The onset and duration of anesthesia were monitored using an electric pulp tester. No statistically significant differences were seen in the onset and duration of anesthesia between the articaine and lidocaine solutions. PMID:7943919

    Major technical and pharmacological achievements in recent years have greatly influenced the practice of anesthesia. Clinical signs related to the main aspects of anesthesia, i.e., hypnosis, analgesia, and muscular relaxation, are increasingly obtainable from variables supplied by the monitoring equipment. It is not known, however, to what extent more indirect, patient-associated clinical signs of pain/depth of anesthesia are still considered of importance and relied on in the intraoperative management of surgical patients. The aims of the present study were to assess what clinical signs, indirect as well as monitor-derived, are considered indicative of intraoperative pain or depth of anesthesia by nurse anesthetists during general anesthesia. In connection with anesthetic management of surgical patients, Swedish nurse anesthetists (N = 40) were interviewed about clinical signs that they routinely assessed and were asked if the observed signs were considered indicative mainly of intraoperative pain or depth of anesthesia. It was found that skin-associated responses (temperature, color, moisture/stickiness) were commonly considered to indicate intraoperative pain rather than depth of anesthesia. Respiratory movements, eye reactions, and circulatory responses were considered to be indicative of either pain or insufficient depth of anesthesia. The present data indicate that indirect physiological signs are still considered of major importance by anesthesia nurses during the anesthetic management of surgical patients. PMID:11759565

    Full Text Available In obstetrics postoperative cognitive dysfunctions may take place after caesarean section and vaginal delivery with poor results both for mother and child. The goal was to study influence of anesthesia techniques following caesarian section on memory, perception and speech. Having agreed with local ethics committee and obtained informed consent depending on anesthesia method, pregnant women were divided into 2 groups: 1st group (n=31 had spinal anesthesia, 2nd group (n=34 – total intravenous anesthesia. Spinal anesthesia: 1.8-2.2 mLs of hyperbaric 0.5% bupivacaine. ТIVА: Thiopental sodium (4 mgs kg-1, succinylcholine (1-1.5 mgs kg-1. Phentanyl (10-5-3 µgs kg-1 hour and Diazepam (10 mgs were used after newborn extraction. We used Luria’s test for memory assessment, perception was studied by test “recognition of time”. Speech was studied by test "name of fingers". Control points: 1 - before the surgery, 2 - in 24h after the caesarian section, 3 - on day 3 after surgery, 4 - at discharge from hospital (5-7th day. The study showed that initially decreased memory level in expectant mothers regressed along with the time after caesarean section. Memory is restored in 3 days after surgery regardless of anesthesia techniques. In spinal anesthesia on 5-7th postoperative day memory level exceeds that of used in total intravenous anesthesia. The perception and speech do not depend on the term of postoperative period. Anesthesia technique does not influence perception and speech restoration after caesarean sections.

    Full Text Available Background: chronic anal fissure is one of the most frequent proctological disorders in Western populations. Open lateral internal sphincterotomy is one of the therapeutic options accepted as the treatment of choice for chronic anal fissure, since it reduces the hypertonia of the internal anal sphincter (the main etiopathogenic mechanism of fissures, decreases anal pain, and allows the fissure to heal. Material and methods: we carried out a prospective study of 120 patients operated on for chronic anal fissure with open sphincterotomy under local anesthesia at our Proctology Outpatient Unit from 1998 to 2001. No preoperative studies, bowel preparation, or antibiotic prophylaxis were carried out. All patients were followed up after 1 week, 2 months, 6 months, and 1 year, and underwent an anal manometry before and after surgery. Results: early complications: 3 hematoma-ecchymosis of the wound (2.5%, 3 self-limited hemorrhage events (2.5%. No hemorrhoidal thrombosis, fistulas, or perianal abscesses occurred. Fissures recurred in nine patients (7.5% within one year. The initial rate of incontinence of 7.5% at two months dropped down to 5% at six months. The mean resting pressure (MRP in incontinent patients was lower than in continent patients (55±7 mmHg versus 80.7 ± 21 mmHg. The difference in mean squeeze pressure (MSP between incontinent patients and continent patients was not statistically significant. Conclusions: open sphincterotomy under local anesthesia has a long-term rate of healing and a morbidity rate similar to other techniques. It may therefore be considered an effective treatment for chronic anal fissure.Introducción: la fisura anal crónica sigue siendo uno de los problemas proctológicos más frecuentes e incapacitantes en la población occidental actual.

  5. Nerves and Anesthesia: A physics perspective on medicine

    CERN Document Server

    Heimburg, Thomas

    2014-01-01

    We present a recent theory for nerve pulse propagation and anesthesia and argue that both nerve activity and the action of anesthetics can be understood on the basis of simple physical laws. It was found experimentally that biological membranes melt from a solid state to a liquid state just below physiological temperature. Such melting processes have a profound influence on the physical properties of cell membranes. They make it possible for mechanical pulses (solitons) to travel along nerve axons. In these pulses, a region of solid phase travels in the liquid nerve membrane. These pulses display many properties associated with the action potential in nerves. Both general and local anesthetics lower melting temperatures of membranes. Thus, they make it more difficult to excite the nerve membrane. Since hydrostatic pressure increases melting temperatures, it counteracts anesthesia. This theory has the virtue of providing a simple explanation of the famous Meyer-Overton correlation, which states that the effect...

    The partial intravenous anesthesia technique (PIVA) is used to lower the inspired concentration of an inhalational anesthetic by concurrent use of injectable drugs. This technique reduces the incidence of undesirable side-effects and provides superior quality of anesthesia and analgesia. Drugs commonly used for PIVA include opioids, alpha-2 adrenergic agonists, injectable anesthetic agents, and lidocaine. Most are administered by intravenous infusion.

    1993-11-01

    Spinal anesthetic is a common form of surgical anesthetic used in foot and ankle surgery. Spinal morphine anesthetic is less common, but has the advantage of providing postoperative analgesia for 12 to 24 hr. A number of complications can occur with spinal anesthesia, including urinary retention that may be a source of severe and often prolonged discomfort and pain for the patient. Management of this problem may require repeated bladder catheterization, which may lead to urinary tract infections or impairment of urethrovesicular function. This study reviews the incidence of urinary retention in 80 patients (40 after general anesthesia and 40 after spinal anesthesia) who underwent foot and ankle surgery at Saint Joseph's Hospital, Philadelphia, PA. Twenty-five percent of the patients who had spinal anesthesia experienced urinary retention, while only 7 1/2% of the group who had general anesthesia had this complication. Predisposing factors, treatment regimen, and recommendations for the prevention and management of urinary retention are presented.

    This study sought to measure current attitudes toward hypnosis among anesthesia providers using an in-person survey distributed at a single grand rounds at a single academic teaching hospital. One hundred twenty-six anesthesia providers (anesthesiologists and nurse anesthetists) were included in this study. A 10-question Institutional Review Board (IRB)-approved questionnaire was developed. One hundred twenty-six (73% of providers at the meeting) anesthesia providers completed the survey. Of the respondents, 54 (43%) were anesthesiologists, 42 (33%) were trainees (interns/residents/fellows) in anesthesia, and 30 (24%) were nurse anesthetists. Over 70% of providers, at each level of training, rated their knowledge of hypnosis as either below average or having no knowledge. Fifty-two (42%) providers agreed or strongly agreed that hypnotherapy has a place in the clinical practice of anesthesia, while 103 (83%) believed that positive suggestion has a place in the clinical practice of anesthesia (p hypnosis were that it is too time consuming (41%) and requires special training (34%). Only three respondents (2%) believed that there were no reasons for using hypnosis in their practice. These data suggest that there is a self-reported lack of knowledge about hypnosis among anesthesia providers, although many anesthesia providers are open to the use of hypnosis in their clinical practice. Anesthesia providers are more likely to support the use of positive suggestion in their practice than hypnosis. Practical concerns should be addressed if hypnosis and therapeutic verbal techniques are to gain more widespread use.

    Purpose: To evaluate the feasibility, reliability and analgesia effect of topical anesthesia combined with subconjunctival anesthesia in anti-glaucomatous surgery.Methods: Two hundred and four cases (357 eyes) underwent anti-glaucomatous surgeries under topical anesthesia with 0.5% Alcaine eye drops combined with subconjunctival anesthesia with 2% Lidocaine. The analgesic effect was analysed with visual analogue pain scale.Results: Among all of 357 eyes, 62 eyes underwent peripheral iridectomy, 67 eyes underwent simple trabeculectomy, 167 eyes underwent compound brabeculectomy and 12 eyes nonpenetrating trabecular surgery. The effects of anesthesia were as follows: 304 eyes(85.2%) were painless (Grade I ), 50 eyes (14.0%) were slight painful (Grade Ⅱ ), and 3 eyes (0.8%) were more painful (Grade Ⅲ ) during surgery. And no severe complications were observed in all the cases during surgery and postoperatively. Amaurosis fugax was not observed in the glaucoma patients at the late stage with narrow visual fields and poor visual ability.Conclusion: Topical anesthesia combined with subconjunctival anesthesia is effective,safe and simple anesthesia alternative in routine anti-glaucomatous surgery, especially for the glaucoma patients at the late stage with narrow visual fields and poor visual ability. It is worthy of being applied widely.

    1993-10-01

    The aim of the present study was to investigate the effect of epidural analgesia combined with general anesthesia on hemodynamics. Thirty patients undergoing surgery for the treatment of cancer of the neck were studied. The patients were divided into two groups of those who received epidural analgesia combined with general anesthesia group (Group 1) and those with general anesthesia alone (Group 2). Blood pressure was not different between the groups. But heart rate and rate pressure products in Group 1 were significantly lower than those of Group 2. CVP in Group 1 increased significantly to 10.1 +/- 2.9 mmHg during surgery from 6.8 +/- 1.8 mmHg at the beginning of the surgery. There was no difference in intraoperative blood loss and the amount of fluid infused between the two groups. These results suggest that epidural anesthesia combined with general anesthesia is effective to stabilize hemodynamics during cervical surgery, but we have to be careful about using local anesthetics during long cervical procedures, because it increases CVP which might result from the depression of cardiac function.

Methods: Regional anesthesia fellowship directors across the world were asked to complete a comprehensive survey that detailed the range of educational and practical experience and attitudes as well as assessment procedures offered in their programs. Results: The survey response rate was 66% (45/68. Overall, the range of activities and the time and resources committed to education during fellowships is encouraging. A wide range of nerve block experience is reported with most programs also offering acute pain management, research, and teaching opportunities. Only two-thirds of fellowships provide formal feedback. This feedback is typically a formative assessment. Conclusion: This is the first survey of regional anesthesia fellowship directors, and it illustrates the international scope and continuing expansion of education and training in the field. The results should be of interest to program directors seeking to benchmark and improve their educational programs and to faculty involved in further curriculum development.

    Full Text Available Regional anesthesia in children was first studied by August Bier in 1899. Since then, spinal anesthesia was known to be practiced for several years with a series of cases published as early as in 1909-1910. (1 In 1900, Bainbridge reported a case of strangulated hernia repair under spinal anesthesia in an infant of three months(2. Thereafter, Tyrell Gray, a British surgeon published a series of 200 cases of lower abdominal surgeries in infants and children under spinal anesthesia in 1909-1910. The appearance of neuromuscular blocking agents and the development of volatile anesthetics in the forties shifted the techniques toward general anesthesia. However, spinal pediatric anesthesia did not disappear. In 1901, Sicard and Cathelin introduced independently the caudal approach in the anesthetic practice. The first publication that mentions this technique in children was written by Campbell in 1933 and the second one by Leigh and Belton in 1951. Subsequently, Fortuna (1963 in Brazil, Melman(10 (1973 in Mexico, Takasaki (1977 in Japan, Ecoffey(7 (1985 in France, and Rash (1995 in USA, introduced these techniques in their countries. The caudal technique is extensively described by Key in 1994. When regional anesthesia is given to older children, some variables such as the intervention site, age, and presence of chronic disease, cooperativeness and parental preferences should be considered. In present study we compared caudal block with spinal block in pediatric patients.

    Full Text Available Vertical infraclavicular brachial plexus block is utilized in patients with chronic renal failure at the time of creation of an arterio-venous fistula (AVF. The aim of this study is to test the effect of impaired renal function, with the resulting deranged serum electrolytes and blood gases, on the success rate and the onset of action of the local anesthetics used. In this prospective clinical study, we investigated the effect of the serum levels of sodium, potassium, urea, crea-tinine, pH, and bicarbonate on the onset of action of a mixture of lidocaine and bupivacaine administered to create infraclavicular brachial plexus block. A total of 31 patients were studied. The success rate of the block was 93.5 % (29 patients. The mean onset time for impaired or re-duced sensation was found to be 8.9 ± 4.7 mins and for complete loss of sensation, was 21.2 ± 6.7 mins. There was no significant association with serum sodium, potassium, urea, creatinine or the blood pH level (P> 0.05. The bivariate correlation between serum bicarbonate level and the partial and complete sensory loss was -0.714 and -0.433 respectively, with significant correlation (P= 0.00, 0.019. Our study suggests that infraclavicular block in patients with chronic renal failure carries a high success rate; the onset of the block is delayed in patients with low serum bicarbonate levels.

    Deep isoflurane anesthesia initiates a burst suppression pattern in which high-amplitude bursts are preceded by periods of nearly silent electroencephalogram. The burst suppression ratio (BSR) is the percentage of suppression (silent electroencephalogram) during the burst suppression pattern and is one parameter used to assess anesthesia depth. We investigated cortical burst activity in rats in response to different auditory stimuli presented during the burst suppression state. We noted a rapid appearance of bursts and a significant decrease in the BSR during stimulation. The BSR changes were distinctive for the different stimuli applied, and the BSR decreased significantly more when stimulated with a voice familiar to the rat as compared with an unfamiliar voice. These results show that the cortex can show differential sensory responses during deep isoflurane anesthesia.

    This study sought to measure current attitudes toward hypnosis among anesthesia providers using an in-person survey distributed at a single grand rounds at a single academic teaching hospital. One hundred twenty-six anesthesia providers (anesthesiologists and nurse anesthetists) were included in this study. A 10-question Institutional Review Board (IRB)-approved questionnaire was developed. One hundred twenty-six (73% of providers at the meeting) anesthesia providers completed the survey. Of the respondents, 54 (43%) were anesthesiologists, 42 (33%) were trainees (interns/residents/fellows) in anesthesia, and 30 (24%) were nurse anesthetists. Over 70% of providers, at each level of training, rated their knowledge of hypnosis as either below average or having no knowledge. Fifty-two (42%) providers agreed or strongly agreed that hypnotherapy has a place in the clinical practice of anesthesia, while 103 (83%) believed that positive suggestion has a place in the clinical practice of anesthesia (p hypnosis were that it is too time consuming (41%) and requires special training (34%). Only three respondents (2%) believed that there were no reasons for using hypnosis in their practice. These data suggest that there is a self-reported lack of knowledge about hypnosis among anesthesia providers, although many anesthesia providers are open to the use of hypnosis in their clinical practice. Anesthesia providers are more likely to support the use of positive suggestion in their practice than hypnosis. Practical concerns should be addressed if hypnosis and therapeutic verbal techniques are to gain more widespread use. PMID:27003489

This is especially imperative when speaking to the parents of children who will be operated on for minor procedures: in our experience, they tend to think that the anesthesia will be a light anesthesia without risks. Often the surgeons tell them that the operation is very simple without stressing the fact that it will be done under general anesthesia which is identical to the one we give for major operations. Different is the scenario for the parents of children who are affected by malignant neoplasms: in these cases they already know that the illness is serious. They have this tremendous burden and we choose not to add another one by discussing anesthetic risks, so we usually go along with the examination of the child without bringing up the possibility of complications, unless there is some specific problem such as a mediastinal mass.

  9. A Wavelet Transform Based Method to Determine Depth of Anesthesia to Prevent Awareness during General Anesthesia

    Full Text Available Awareness during general anesthesia for its serious psychological effects on patients and some juristically problems for anesthetists has been an important challenge during past decades. Monitoring depth of anesthesia is a fundamental solution to this problem. The induction of anesthesia alters frequency and mean of amplitudes of the electroencephalogram (EEG, and its phase couplings. We analyzed EEG changes for phase coupling between delta and alpha subbands using a new algorithm for depth of general anesthesia measurement based on complex wavelet transform (CWT in patients anesthetized by Propofol. Entropy and histogram of modulated signals were calculated by taking bispectral index (BIS values as reference. Entropies corresponding to different BIS intervals using Mann-Whitney U test showed that they had different continuous distributions. The results demonstrated that there is a phase coupling between 3 and 4 Hz in delta and 8-9 Hz in alpha subbands and these changes are shown better at the channel T7 of EEG. Moreover, when BIS values increase, the entropy value of modulated signal also increases and vice versa. In addition, measuring phase coupling between delta and alpha subbands of EEG signals through continuous CWT analysis reveals the depth of anesthesia level. As a result, awareness during anesthesia can be prevented.

    Modern anesthetic techniques are superior to regional anesthesia for most operative procedures. Yet because of new advances in techniques and methods and sound pathophysiological knowledge, there are some operations for which regional anesthesia has distinct advantages over general anesthesia. This is the case, for example, in geriatric surgery. Here, the technical simplicity and short amount of time required give spinal anesthesia marked advantages over general anesthesia. Post-spinal headaches and slight falls in blood pressure have become rarer due to technical innovations and can reasonably be accepted. PMID:825724

    There has been an increasing tendency for anesthesiologists to be responsible for providing sedation or anesthesia during chest CT imaging in young children. Anesthesia-related atelectasis noted on chest CT imaging has proven to be a common and troublesome problem, affecting image quality and diagnostic sensitivity. To evaluate the safety and effectiveness of a standardized anesthesia, lung recruitment, controlled-ventilation technique developed at our institution to prevent atelectasis for chest CT imaging in young children. Fifty-six chest CT scans were obtained in 42 children using a research-based intubation, lung recruitment and controlled-ventilation CT scanning protocol. These studies were compared with 70 non-protocolized chest CT scans under anesthesia taken from 18 of the same children, who were tested at different times, without the specific lung recruitment and controlled-ventilation technique. Two radiology readers scored all inspiratory chest CT scans for overall CT quality and atelectasis. Detailed cardiorespiratory parameters were evaluated at baseline, and during recruitment and inspiratory imaging on 21 controlled-ventilation cases and 8 control cases. Significant differences were noted between groups for both quality and atelectasis scores with optimal scoring demonstrated in the controlled-ventilation cases where 70% were rated very good to excellent quality scans compared with only 24% of non-protocol cases. There was no or minimal atelectasis in 48% of the controlled ventilation cases compared to 51% of non-protocol cases with segmental, multisegmental or lobar atelectasis present. No significant difference in cardiorespiratory parameters was found between controlled ventilation and other chest CT cases and no procedure-related adverse events occurred. Controlled-ventilation infant CT scanning under general anesthesia, utilizing intubation and recruitment maneuvers followed by chest CT scans, appears to be a safe and effective method to obtain

    Neural plasticity changes within the olfactory bulb are important for olfactory learning, although how neural encoding changes support new associations with specific odors and whether they can be investigated under anesthesia, remain unclear. Using the social transmission of food preference olfactory learning paradigm in mice in conjunction with in vivo microdialysis sampling we have shown firstly that a learned preference for a scented food odor smelled on the breath of a demonstrator animal occurs under isofluorane anesthesia. Furthermore, subsequent exposure to this cued odor under anesthesia promotes the same pattern of increased release of glutamate and gamma-aminobutyric acid (GABA) in the olfactory bulb as previously found in conscious animals following olfactory learning, and evoked GABA release was positively correlated with the amount of scented food eaten. In a second experiment, multiarray (24 electrodes) electrophysiological recordings were made from olfactory bulb mitral cells under isofluorane anesthesia before, during and after a novel scented food odor was paired with carbon disulfide. Results showed significant increases in overall firing frequency to the cued-odor during and after learning and decreases in response to an uncued odor. Analysis of patterns of changes in individual neurons revealed that a substantial proportion (>50%) of them significantly changed their response profiles during and after learning with most of those previously inhibited becoming excited. A large number of cells exhibiting no response to the odors prior to learning were either excited or inhibited afterwards. With the uncued odor many previously responsive cells became unresponsive or inhibited. Learning associated changes only occurred in the posterior part of the olfactory bulb. Thus olfactory learning under anesthesia promotes extensive, but spatially distinct, changes in mitral cell networks to both cued and uncued odors as well as in evoked glutamate and GABA

    Abstract Currently, no reported studies have evaluated intraoperative handover among anesthesia providers. Studies on anesthetic handover in the US recovery room setting observed that handover processes are insufficient and, in many instances, significant intraoperative events are disregarded. An online survey tool was sent to anesthesia providers at US anesthesia residency programs nationwide (120 out of the 132 US programs encompassing around 4500 residents and their academic MDAs) and a smaller survey selection of CRNAs (10 institutions about 300 CRNAs in the metropolitan area of Detroit, MI, USA) to collect information on handover practices. The response rate to this survey (n = 216) was comprised of approximately 5% (n = 71) of the resident population in US anesthesia programs, 5% (n = 87) of MDAs , and 20% (n = 58) of the CRNAs. Out of all respondents (n = 212), 49.1 % had no hand-over protocol at their institution and 88% of respondents who did have institutional handover protocols believed them insufficient for effective patient handover. In addiiton, 84.8% of all responders reported situations where there was insufficient information received during a patient handover. Only 7% of the respondents reported never experiencing complications or mismanagement due to poor or incomplete hand-overs. In contrast, 60% reported rarely having complications, 31% reported sometimes having complications, and 3% reported frequent complications. In conclusion, handover transition of patient care is a vulnerable and potentially life-threatening event in the operating room. Our preliminary study suggests that current intraoperatvive handover practices among anesthesia providers are suboptimal and that national patient handover guidelines are required to improve patient safety.

    Onur Kaygisiz

    2007-08-01

    Full Text Available OBJECTIVE: Transrectal ultrasound (TRUS guided prostate biopsy is well tolerated by patients but the lack of an effective marker to predict pain prevents us from determining pre-procedurally which patient group needs local anesthesia for biopsy and probe pain. Thus in this study, we investigated predictor factors for prostate biopsy and probe insertion pain. MATERIALS AND METHODS: 71 patients who were undergoing prostate biopsy without anesthesia were included in the study retrospectively. Pain had been assessed with visual analogue scale (VAS 0-10. Digital rectal examination (DRE pain was analyzed for biopsy and probe insertion pain. RESULTS: DRE pain was related to both probe pain and biopsy pain. CONCLUSION: Although level of pain during DRE determines patients in need of local anesthesia, since the number of patients with moderate-severe pain is rather big, it seems efficient in determining the patients in need of additional anesthesia due to probe pain.

    Documenting a patient's anesthetic in the medical record is quite different from summarizing an office visit, writing a surgical procedure note, or recording other clinical encounters. Some of the biggest differences are the frequent sampling of physiologic data, volume of data, and diversity of data collected. The goal of the anesthesia record is to accurately and comprehensively capture a patient's anesthetic experience in a succinct format. Having ready access to physiologic trends is essential to allowing anesthesiologists to make proper diagnoses and treatment decisions. Although the value provided by anesthesia information management systems and their functions may be different than other electronic health records, the real benefits of an anesthesia information management system depend on having it fully integrated with the other health information technologies. An anesthesia information management system is built around the electronic anesthesia record and incorporates anesthesia-relevant data pulled from disparate systems such as laboratory, billing, imaging, communication, pharmacy, and scheduling. The ability of an anesthesia information management system to collect data automatically enables anesthesiologists to reliably create an accurate record at all times, regardless of other concurrent demands. These systems also have the potential to convert large volumes of data into actionable information for outcomes research and quality-improvement initiatives. Developing a system to validate the data is crucial in conducting outcomes research using large datasets. Technology innovations outside of healthcare, such as multitouch interfaces, near-instant software response times, powerful but simple search capabilities, and intuitive designs, have raised the bar for users' expectations of health information technology.

    Myasthenia gravis is an autoimmune disease with antibodies directed against the acetylcholine receptor at the neuromuscular junction. Anesthetists have a special interest in myasthenia gravis because of its interaction with various anesthetic agents. Unlike adult myasthenic patients; very little report has been written about the anesthetic management in children, other than in relation to thymectomy. Although the use of caudal anesthesia in pediatric patients is common, have not seen any report concerning its use in a myasthenic child. In this case report, we represented a 2 year-old boy was performed caudal anesthesia for orchiopexy operation. He had presented difficulty in breathing, generalized weakness and droopy eyes due to congenital myasthenia gravis. In the operating room, following the routine monitoring, the patient was sedated with intravenous 1mg midazolam and 10 mg ketamine. Then caudal block was performed. 17 minutes later from the local anesthetic injection; operation was started and lasted 45 minutes. The patient did not require intraoperative supplemental analgesia and postoperative course was uneventful. Specific attention should be paid to voluntary and respiratory muscle strength in myasthenia gravis patients. Caudal anesthesia allowed airway control of myasthenia gravis patients without endotracheal intubations and muscle relaxant. In conclusion, we think that caudal anesthetic technique may be considered as a safe and suitable for the myasthenic child and it may represent a valid alternative to general anesthesia for these patients.

  6. The heart rate variability when conducting anesthesia

    2016-03-01

    Full Text Available The study was performed on the base of 10 years of using different methods of analysis of heart rate variability as an indicator of direct and reverse connection of the sympatho-adrenal system in the preoperative diagnosis and anesthetic monitoring. The possibility of predicting the depth of anaesthesia was analyzed, for depending on significant amounts of external and internal conditions, the level of anesthesia changes significantly. In this regard the influence of drugs and technological means of influencing the condition of all life-supporting systems, and the autonomic nervous system in particular, before, during and after anesthesia is of great practical interest. The balance of the pharmacological protection of the vegetative balance in the surgical aggression is studied, as well as the use of heart rate variability as a non-specific method in relation to nosological forms of pathology, both under internal and external influences. A review of a number of sources confirms that heart rate is virtually the only high-speed method to present the sympatho-vagal regulation, the most accessible somatic parameter for estimation of the cardiovascular system functioning in anesthesiology. The heart rate variability serves as an indicator of functional condition of autonomous (vegetative nervous system. It is proposed to perform the continuous monitoring of the autonomic indices of the heart rhythm, which allows to register sympaho-vagal imbalance. Dynamic monitoring, timely interpretation of heart rate variability are constantly in the spotlight, but the approach and methodology of the domestic and foreign authors distinctly differ on the following points: heart rythmography as a visual method of assessing information about the dynamics of slow-wave processes, spectral analysis of the heart sinus rhythm as the best method of analysis of large and small wave activity, tests of functional diagnostics for subsequent measurement of the autonomic nervous

    Anesthesia services are increasingly being requested for gastrointestinal (GI) endoscopy procedures. The preparation of the patients is different from the traditional operating room practice. The responsibility to optimize comorbid conditions is also unclear. The anesthetic techniques are unique to the procedures, as are the likely events that require intervention by the anesthesia team. The postprocedure care is also unique. The future needs for anesthesia services in GI endoscopy suite are likely to expand with further developments of the technology.

    Pharmacologic MRI (phMRI) is a non-invasive in vivo imaging method, which can evaluate the drug effects on the brain and provide complementary information to ex vivo techniques. The preclinical phMRI studies usually require anesthesia to reduce the motion and stress of the animals. The anesthesia, however, is a crucial part of the experimental design, as it may modulate the neural drug-induced (de)activation and hemodynamic coupling. Therefore, the aim of the present study was to address this methodologic question by performing phMRI experiments with five anesthetics (α-chloralose, isoflurane, medetomidine, thiobutabarbital, and urethane) and seven anesthesia protocols. Nicotine, a widely studied psychostimulant, was administered to rats while measuring blood oxygenation level-dependent (BOLD) signals. Notably different responses were observed depending on the anesthetic used. The highest responses were measured in urethane-anesthetized rats whereas the responses were hardly noticeable in α-chloralose group. As urethane is not commonly used in phMRI, hemodynamic coupling under urethane anesthesia was investigated with functional cerebral blood flow (CBF) and volume-weighted (CBVw) imaging, and simultaneous electrophysiologic and BOLD measurements. The BOLD, CBF, and CBVw measurements in response to nicotine were highly correlated (R(2) ≥ 0.70, p<0.001). BOLD values correlated well (R(2)=0.43, p<10(-6)) with local field potential (LFP) spectral power (13-70Hz) during pharmacologic stimulation. These findings indicate that urethane anesthesia combined with BOLD contrast provides a robust protocol for nicotine phMRI studies. As urethane has mild effects to individual receptor systems, and coupling between electrophysiologic activity and hemodynamic response is maintained, this anesthetic may also be suitable for other phMRI studies.

    Gingival overgrowth/hyperplasia can be attributed to several causes, but drug-induced gingival overgrowth/hyperplasia arises secondarily to prolonged use of antihypertensive drugs, anticonvulsants and immunosuppressants. The management is complex in nature considering the multitude of factors involved such as substitution of drug strict plaque control along with excision of the tissue to be performed under local anesthesia as outpatient. In the recent times, the patient's psychological fear of the treatment with the use of surgical blade and multiple visits has developed the concept of single visit treatment under general anesthesia incorporating a laser as viable option. The present case highlights the new method of management of gingival overgrowth.

    Various EEG features have been used in depth of anesthesia (DOA) studies. The objective of this study was to find the excellent features or combination of them than can discriminate between different anesthesia states. Conducting a clinical study on 22 patients we could define 4 distinct anesthetic states: awake, moderate, general anesthesia, and isoelectric. We examined features that have been used in earlier studies using single-channel EEG signal processing method. The maximum accuracy (99.02%) achieved using approximate entropy as the feature. Some other features could well discriminate a particular state of anesthesia. We could completely classify the patterns by means of 3 features and Bayesian classifier.

    Background Loss of consciousness is an essential feature of general anesthesia. Although alterations of neural networks during anesthesia have been identified in the spatial domain, there has been relatively little study of temporal organization. Methods Ten normal male volunteers were anesthetized with an induction dose of propofol on two separate occasions. The duration of network connections in the brain was analyzed by multichannel electroencephalography and the minimum spanning tree method. Entropy of the connections was calculated based on Shannon entropy. The global temporal configuration of networks was investigated by constructing the cumulative distribution function of connection times in different frequency bands and different states of consciousness. Results General anesthesia was associated with a significant reduction in the number of network connections, as well as significant alterations of their duration. These changes were most prominent in the delta bandwidth and were also associated with a significant reduction in entropy of the connection matrix. Despite these and other changes, a global “scale-free” organization was consistently preserved across multiple subjects, multiple anesthetic exposures, multiple states of consciousness and multiple frequencies of the electroencephalogram. Conclusions Our data suggest a fundamental principle of temporal organization of network connectivity that is maintained during both consciousness and anesthesia, despite local changes. These findings are consistent with a process of adaptive reconfiguration during general anesthesia. PMID:20881595

    The sleep homeostatic response significantly affects the state of anesthesia. In addition, sleep recovery may occur during anesthesia, either via a natural sleep-like process to occur or via a direct restorative effect. Little is known about the effects of isoflurane anesthesia on sleep homeostasis. We investigated whether 1) isoflurane anesthesia could provide a sleep-like process, and 2) the depth of anesthesia could differently affect the post-anesthesia sleep response. Nine rats were trea...

    Full Text Available Background: Because of airway stimulations during the bronchoscopy and lack of direct access to the airway, preferred method of anesthesia for rigid bronchoscopy is already controversial. In this study we compared inhalation anesthesia with total intravenous anesthesia (TIVA for rigid bronchoscopy. Method and Materials: 30 patients aged 2-6 years were chosen divided on two same groups. Anesthesia in group I maintained with halothane and in group II maintained with remifentanil and propofol. Oxygenation, heart rate, respiratory rate, coughing, bucking, laryngospasm, bronchospasm were evaluated during and after surgery. Also Operation success and surgeon’s satisfaction were recorded as well.Results: Demographic findings were the same in both groups. Oxygenation and heart rate were more stable in group II (P=0.047 and P=0.026 respectively but there was no significant difference in respiratory rate between two groups (P=1. Success rate was also similar in both groups but surgeon’s satisfaction was significantly higher in TIVA (P=0.003. There was not any significant different between complications in two groups. Conclusion: We suggest TIVA for rigid bronchoscopy because of better oxygenation, more homodynamic stability, surgeon’s satisfaction, lack of air pollution and less interference with surgeon’s visual field.

    2012-04-01

    Part 2 of this review on geriatric anesthesia primarily describes the multiple influences of age on the pharmacokinetics and pharmacodynamics of different anesthetic agents and their impact on clinical practice. In the elderly the demand for opioids is reduced by almost 50% and with total intravenous anesthesia the dosages of propofol and remifentanil as well as recovery times are more determined by patient age than by body weight. As a result depth of anesthesia monitoring is recommended for geriatric patients to individually adjust the dosing to patients needs. With muscle relaxants both delayed onset of action and prolonged duration of drug effects must be considered with increasing age and as this may lead to respiratory complications, neuromuscular monitoring is highly recommended. The following measures appear to be beneficial for geriatric patients: thorough preoperative assessment, extended hemodynamic monitoring, use of short-acting anesthetics in individually adjusted doses best tailored by depth of anesthesia monitoring, intraoperative normotension, normothermia and normocapnia, complete neuromuscular recovery at the end of the procedure and well-planned postoperative pain management in order to reduce or avoid the use of opioids.

    Full Text Available BACKGROUND: Given the expanding role of the anesthesiologist as the “total perioperative physician,” the increasing number of invasive procedures performed by anesthesiologists, and the increase in the prevalence of emerging diseases, stringent attention to infection control practices is paramount. AIM : To find out the bacterial contamination of anesthesia machine and internal lumen of the injection port of peri pheral intravenous cannula, and evaluation of its risk factors during general anesthesia procedures. MATERIALS AND METHODS: 50 general anaesthesia procedures were selected randomly after the approval of ethics committee and informed consent from the patien t. Samples were taken for bacterial culture on 2 sites in anesthesia machine (Adjustable pressure limiting valve {APL} and agent concentration dial of inhaled anesthetics{AD} and internal lumen of the injection port of peripheral intravenous cannula befor e starting and after completion of procedures. Bacteria and colony count were identified according to standard laboratory methods . RESULTS : Adjustable pressure limiting valve area was contaminated with bacteria in 12% (6/50 before starting procedure and 34% (17/50 after completion of procedures. Agent concentration dial of inhaled anesthetic site was contaminated with bacteria in 10% (5/50 before starting procedure and 28% (14/50 after completion of procedures. Bacterial contamination occurred in the i nternal lumen of the injection port of peripheral intravenous cannula in 16% (8/50 during general anesthesia. Isolated bacteria in anesthesia machine and peripheral intra venous cannula sites are STAPHYLO COCCI, STREPTOCOCCI, MICRO COCCI, ENTERO COCCI, E. COLI, and PSEUDOMONAS . CONCLUSION: Bacterial contamination is significantly associated with procedure order in a day (bacterial contamination rate is increased from first procedure to fifth procedure in a day. It is significantly associated with surgical s pecialty highest in

    A 32-year-old man with severe pulmonary arterial hypertension and Eisenmenger syndrome secondary to congenital ventricular septal defects presented for ventriculoperitoneal shunt insertion. Consultation between surgical and anesthesia teams acknowledged the extreme risk of performing this case, but given ongoing symptoms related to increased intracranial pressure from a large third ventricle colloid cyst, the case was deemed urgent. After a full discussion with the patient, including an explanation of anesthetic expectations and perioperative risks, the case was performed under monitored anesthesia care. Anesthetic management included high-flow nasal cannula oxygen with capnography and arterial blood pressure monitoring, dexmedetomidine infusion, boluses of midazolam and ketamine, and local anesthetic infiltration of the cranial and abdominal incisions as well as the catheter track. Hemodynamic support was provided with an epinephrine infusion, small vasopressin boluses, and inhaled nitric oxide. The patient recovered without any significant problems and was discharged home on postoperative day 3. PMID:27224039

    Background Difficult airway remains not only a challenge to the anesthesiologists,but also a life-threatening event to the patients.Awake intubation is the principal choice to deal with difficult airway,and a key point for awake intubation is airway topical anesthesia.Yet,so far there is no ideal topical anesthesia approach for awake intubation.This study aimed at evaluating the effect of pressure-driven (by 10 L/min oxygen flow) lidocaine spray on airway topical anesthesia in order to find a powerful and convenient method for airway topical anesthesia for conscious sedation intubation.Methods Thirty adult patients referred for elective surgery under general anesthesia,aged 18-60 years and Mallampati class Ⅰ or Ⅱ,were recruited for the study.Before topical anesthesia,the observer's assessment of alert and sedation (OAA/S) scale was controlled between 3 and 4 by intravenous midazolam (0.03 mg/kg),propofol (2 mg.kg1·h-1) andremifentanil (0.05 μg.kg-1·min-1).Ten minutes after sedation,topical anesthesia was performed with the pressure-driven lidocaine spray; the driving pressure was achieved by an oxygen flow of 10 L/min.After topical anesthesia,tracheal intubation was performed and the intubation condition was assessed with modified the Erhan's intubation condition score by an experienced anesthesiologist,and a score of less than 10 was considered to be satisfactory.Attempts to intubate the patient were recorded,and the complications such as local anesthetic toxicity,mucosa injury,and respiration depression were also recorded.The mean arterial blood pressure (MAP),heart rate (HR) and pulse oxygen saturation (SpO2) were recorded at different time points before and after intubation.Patients were asked 24 hours after the operation whether they could recall the events during intubation.Results All patients were intubated at the first attempt,the average intubation condition score was 7.0±1.1,from 6 to 10,satisfied intubation condition.MAP and HR increased

    Since little has been reported about complications of spinal anesthesia in adult tethered cord syndrome (TCS), we sought to delineate the characteristics of the condition.A total of 4 cases of adult TCS after spinal anesthesia were reviewed. The medical charts of the patients were obtained. Anesthesia, which was combined spinal and epidural anesthesia or spinal anesthesia was performed, and follow-up were carried out in all patients.The most common neurological symptom of adult TCS before surgery was occasional severe pain in back, perineal region, or legs. Frequent micturition, diminished knee and ankle reflexes, and difficulty in bending were exhibited in partial patients. Paraesthesia of perineal region or/and lower extremities existed 2 to 3 days after spinal anesthesia in all the cases. Weakness of lower extremities existed in 1 case. Lumbar magnetic resonance imaging showed the low location of conus medullaris. At follow-up, 3 cases recovered completely within 3 weeks, and 1 case underwent permanent disability.These cases suggest anesthesiologists and surgeons alert to the association of adult TCS and spinal anesthesia. Spinal anesthesia should be prohibited in patients with adult TCS to prevent neurological damages. PMID:27442670

    The human heart normally exhibits robust beat-to-beat heart rate variability (HRV). The loss of this variability is associated with pathology, including disease states such as congestive heart failure (CHF). The effect of general anesthesia on intrinsic HRV is unknown. In this prospective, observational study we enrolled 100 human subjects having elective major surgical procedures under general anesthesia. We recorded continuous heart rate data via continuous electrocardiogram before, during, and after anesthesia, and we assessed HRV of the R-R intervals. We assessed HRV using several common metrics including Detrended Fluctuation Analysis (DFA), Multifractal Analysis, and Multiscale Entropy Analysis. Each of these analyses was done in each of the four clinical phases for each study subject over the course of 24 h: Before anesthesia, during anesthesia, early recovery, and late recovery. On average, we observed a loss of variability on the aforementioned metrics that appeared to correspond to the state of general anesthesia. Following the conclusion of anesthesia, most study subjects appeared to regain their normal HRV, although this did not occur immediately. The resumption of normal HRV was especially delayed on DFA. Qualitatively, the reduction in HRV under anesthesia appears similar to the reduction in HRV observed in CHF. These observations will need to be validated in future studies, and the broader clinical implications of these observations, if any, are unknown.

    The possibility of awareness during general anesthesia causes apprehension for the patient and the Certified Registered Nurse Anesthetist (CRNA). The goals of general anesthesia are to prevent the sensation of pain and produce a state of sedation, hypnosis, and unconsciousness so the patient will not remember the surgical procedure. An inadequate level of anesthesia can result in patient awareness during surgery. The current practice of anesthesia relies on indirect hemodynamic measurements such as blood pressure and heart rate to monitor the sedative hypnotic state of the patient's brain during general anesthesia. Hemodynamic responses are not reliable for predicting awareness just as blood pressure and heart rate are not indicative of consciousness. Electroencephalogram (EEG) waveforms are known to be affected by anesthetics. Characteristic EEG waveforms are a direct indication of the patient's level of consciousness. Unprocessed and computer-processed EEG recordings have been used in an attempt to monitor the patient's level of consciousness during general anesthesia. A raw or unprocessed EEG recording to monitor the level of consciousness during general anesthesia is problematic. The EEG signal is complex, affected by artifact, and it requires a dedicated interpreter. Conventional processed EEG monitoring systems are problematic because of the complexity of the equipment and technical difficulty of reading the EEG recording. The purpose of this article is to describe the history of awareness during anesthesia and introduce a new processed EEG monitor, the Bispectral Index (BIS) (Aspect Medical Systems, Inc., Natick, MA) with implications for future clinical use and research.

    The depth of anesthesia estimation has been one of the most research interests in the field of EEG signal processing in recent decades. In this paper we present a new methodology to quantify the depth of anesthesia by quantifying the dynamic fluctuation of the EEG signal. Extraction of useful information about the nonlinear dynamic of the brain during anesthesia has been proposed with the optimum Fractal Scaling Exponent. This optimum solution is based on the best box sizes in the Detrended Fluctuation Analysis (DFA) algorithm which have meaningful changes at different depth of anesthesia. The Fractal Scaling Exponent (FSE) Index as a new criterion has been proposed. The experimental results confirm that our new Index can clearly discriminate between aware to moderate and deep anesthesia levels. Moreover, it significantly reduces the computational complexity and results in a faster reaction to the transients in patients' consciousness levels in relations with the other algorithms.

    Hypothermia and shivering are common during epidural anesthesia for cesarean delivery but are not always accompanied by a sensation of coldness. To test the hypothesis that central temperature changes are not perceived during epidural anesthesia, we measured central and skin temperatures and thermal perception in 30 patients undergoing cesarean delivery with epidural anesthesia. Central temperature decreased 1.0 +/- 0.6 degrees C from control values during anesthesia and surgery, but thermal perception scores did not reflect central temperatures (P = 0.56) or changes in central temperature (P = 0.63). A feeling of warmth was significantly correlated with increased mean skin temperature (P = 0.02) and increased upper body skin temperature (P = 0.03). We conclude that central temperature is poorly perceived and is less important than skin temperature in determining thermal perception during high levels of epidural anesthesia.

    Leroy D Vandam, MD was a remarkable man--an intricate amalgamation of an artist, scientist, and physician. He was a bastion of medical historical knowledge. Dr Vandam became a most influential anesthesiologist, some say, a giant. He was an example of someone who, with resolve, overcame adversity. His artwork is displayed in countless places, and several of his paintings form part of the Wood Library Museum Heritage Series. Dr Vandam was first a surgeon, but he abandoned surgery and pursued a career in anesthesiology under the leadership of Robert Dripps. He completed his residency training at the University of Pennsylvania and joined its staff in 1949. When he arrived at Brigham and Women's Hospital in the 1950s as director of anesthesia, he embarked on one of the most illustrious careers in American anesthesiology. Dr Vandam published more than 250 original articles, chapters, abstracts, and other reports on a wide variety of subjects including history, art, and pharmacology. His classic article on the complications of neuroaxial blocks is a seminal work in anesthesiology. This article describes how an anesthesiologist who shared an interest with Dr Vandam in the history of anesthesiology came to produce a movie based on his career, the evolution of anesthesia equipment, and the transformation of our specialty.

    Despite the fact that anesthesia was discovered in the United States, we believe that both physicians and nurses are largely unaware of many aspects of the development of the nurse anesthetist profession. A shortage of suitable anesthetists and the reluctance of physicians to provide anesthetics in the second half of the 19th century encouraged nurses to take on this role. We trace the origins of the nurse anesthetist profession and provide biographical information about its pioneers, including Catherine Lawrence, Sister Mary Bernard Sheridan, Alice Magaw, Agatha Cobourg Hodgins, and Helen Lamb. We comment on the role of the nuns and the effect of the support and encouragement of senior surgeons on the development of the specialty. We note the major effect of World Wars I and II on the training and recruitment of nurse anesthetists. We provide information on difficulties faced by nurse anesthetists and how these were overcome. Next, we examine how members of the profession organized, developed training programs, and formalized credentialing and licensing procedures. We conclude by examining the current state of nurse anesthesia practice in the United States. PMID:27041264

    Obesity is associated with serious morbidity during pregnancy, and obese women also are at a high risk of developing complications during labor, leading to an increased risk for instrumental and Cesarean deliveries. The engagement of the obstetrical anesthetist in the management of this group of high-risk patients should be performed antenatally so that an appropriate management strategy can be planned in advance to prevent an adverse outcome. Good communication between all care providers is essential. The obese patient in labor should be encouraged to have a functioning epidural catheter placed early in labor. Apart from providing analgesia and alleviating physiological derangements during labor, the presence of a functioning epidural catheter can also be used to induce anesthesia quickly in the event of an emergency cesarean section, thus avoiding a general anesthesia, which has exceedingly high risks in the obese parturient. Successful management of the obese patient necessitates a comprehensive strategy that encompasses a multidisciplinary and holistic approach from all care-providers.

    Full Text Available Any site in the upper airway can get obstructed and cause noisy breathing as well as dyspnea. These include nasal causes such as choanal atresia or nasal stenosis; pharyngeal causes including lingual thyroid; laryngeal causes such as laryngomalacia; tracheobronchial causes such as tracheal stenosis; and subglottic stenosis. Lesions in the oropharynx may cause stertor, while lesions in the laryngotracheal tree will cause stridor. Subglottic stenosis is the third leading cause of congenital stridors in the neonate. Subglottic Stenosis presents challenges to the anesthesiologist. Therefore, It is imperative to perform a detailed history, physical examination, and characterization of the extent and severity of stenosis. Rigid endoscopy is essential for the preoperative planning of any of the surgical procedures that can be used for correction. Choice of operation is dependent on the surgeon′s comfort, postoperative capabilities, and severity of disease. For high-grade stenosis, single-stage laryngotracheal resection or cricotracheal resection are the best options. It has to be borne in mind that the goal of surgery is to allow for an adequate airway for normal activity without the need for tracheostomy. Anesthesia for airway surgery could be conducted safely with either sevofl uraneor propofol-based total intravenous anesthesia.

To date, there have been a wide variety of simulation applications in this field, and efficacy has largely been assumed. However, a thorough review of the literature reveals that effective teaching strategies, including simulation, in regional anesthesiology and acute pain medicine are not established completely yet. Future research should be directed toward comparative-effectiveness of simulation versus other accepted teaching methods, exploring the combination of procedural training with realistic clinical scenarios, and the application of simulation-based teaching curricula to a wider range of learner, from the student to the practicing physician.Keywords: regional anesthesia, simulation, medical education, ultrasound, nerve block, simulator

Meta-analyses and reviews of acupuncture and related techniques for postoperative nausea and vomiting (POVN and postoperative vomiting (POV show promising results while many clinicians remain skeptical of the value of acupuncture. Given the interest in finding safe non-pharmacological approaches toward postoperative care, this body of knowledge needs to be considered. This review critically appraises and summarizes the research on acupuncture and acupressure in ambulatory anesthesia during the last 15 years.Methods: Articles were identified through searches of Medline, PubMed, and Embase using the search terms “acupuncture” or “acupuncture therapy” in combination with “ambulatory anesthesia” or “ambulatory surgery” or “day surgery” or “postoperative”. A corresponding search was done using “acupressure” and “wristbands”. The searches generated a total of 104, 118, and 122 references, respectively.Results: Sixteen studies were included; eight studies reported on acupuncture and eight on acupressure. Nine studies found acupuncture or acupressure effective on primary endpoints including postoperative nausea and vomiting, postoperative pain, sore throat, and emergence agitation. Four studies found acupuncture had a similar effect to antiemetic medication.Conclusion: Overall, the studies were of fairly good quality. A large proportion of the reviewed papers highlights an effect of acupuncture or acupressure on postoperative morbidities in an ambulatory setting

OBJECTIVE: to assess the patient comfort in pt. with GA and pt. with spinal anaesthesia, the adequate surgical condition, assess the hemodynamic change, assess the post op analgesia and to assess the post op complication. MATERIAL AND METHOD: 60 ASA grade I & II children of either sex, aged 5-12 yrs undergoing elective surgeries for the lower abdominal, perineal and lower limb surgeries were taken. After taking a detailed history, thorough general physical examination, all pertinent investigation were carried out to exclude any systemic disease. Patients were classified randomly into 2 groups (30 patients in each group. Group A: General anesthesia was given. Group P: subarachnoid block was given. Intraoperative monitoring consisted of SPO2, PR, NIBP, RR and assessment of duration of post-operative analgesia. P-value <0.05 consider significant. RESULT: Analysis revealed that there were no significant differences between the patients with respect to age, sex, duration and type of surgery In SAB since less general anaesthetic drug including parental opioid are used the risk and postoperative respiratory depression is minimal. The stress response to surgery is also limited and recovery is fast. Postoperatively complications like sore throat, laryngeal irritation, cough etc. was also less associated with it. CONCLUSION pediatric spinal anesthesia is not only a safe alternative to general anesthesia but often the anesthesia technique of choice in many lower abdominal and lower limb surgeries in children. The misconception regarding its safety and flexibility is broken and is now found to be even more cost effective. It is much preferred technique special for common day case surgeries generally performed in the pediatric age group.

The advantage of ultrasound technology is that it affords the anesthesiologist the real time ability to visualize neural structures, needle advancement, and local anesthetic spread. Recent data suggest that UGRA generates improved success rates and reductions in performance times in comparison to traditional approaches. Further, the use of ultrasound technology in peripheral nerve blocks has provided insight into needle–nerve interactions, revealing distinct limitations of nerve stimulator techniques. Given that UGRA requires a unique set of skills, formal standards and guidelines are currently being developed by leadership societies in order to foster education and training. This review article, in a case vignette format, highlights important techniques, concepts, and limitations regarding the use of ultrasound to facilitate regional anesthesia. Clinically relevant aspects of ultrasound physics are also discussed.Keywords: ultrasound, regional anesthesia

    Full Text Available "nBackground: The function of internal systems can be influenced significantly by hypernatremia, even anesthesia may be affected by this electrolyte imbalance. The aim of this study was to determine the effects of a single anesthetic dose of ketamine in an experimental rat model of chronic hypernatremia. "n"nMethods: Sixty male Wistar rats, weighing 300(±20g, were allocated randomly to three groups: the control group received drinking water and test groups 1 and 2 received 1% and 2% NaCl, respectively, for 144 hours. We measured the parameters of sensitivity to the ketamine injection (125mg/kg including length of times to the inhibition of the righting reflex, inhibition of the response to painful stimulus and the times to the reappearance of the response to painful stimulus and recovery from anesthesia. We also determined the mortality rates during anesthesia. "n"nResults: The times for inhibition of the righting reflex and response to painful stimulus for group 2 were significantly shorter than those for group 1 and the control group. The times for the reappearance of response to painful stimulus and full recovery from anesthesia in group 2 were significantly longer than those of group 1 and the control group. "n"nConclusions: Hypernatremia affects ketamine anesthesia in the rat, increasing the speed of passing through the different steps of anesthesia. The duration of ketamine efficacy increases, while recovery from anesthesia is significantly delayed.

    Anaphylaxis is an acute and fatal systemic allergic reaction to an allergen, and it could be an unpredictable and life-threatening cause during anesthesia. The main purpose of this paper is to report a case of anaphylactic shock during the anesthesia induction and to review the prophylaxis and treatment of anaphylactic reactions and anaphylactoid reactions during the anesthesia period. A 63-year-old man, with a mass on his adrenal, was scheduled to a laparoscopic adrenal tumor excision. During the anesthesia induction period, after administrated sulfentanil, propofol and rocuronium, the blood pressure was decreased and the heart rate was increased. Then, the patient had rash on his whole body and developed an anaphylactic shock. After being treated with the anti-allergic agents and norepinephrine, the rash disappeared and the vital sign become stable. The patient felt nothing uncomfortable during the two weeks'follow-up. Anaphylactic reactions and anaphylactoid reactions are not rare during the anesthesia period. The most common inducements are muscle relaxant, latex and antibiotics. Anaphylactic reactions in the perioperative period are often serious and potentially life-threatening conditions, involving multiple organ systems in which the clinical manifestations are the consequence of the release of preformed mediators from mast cells and basophils. Before anesthesia, we should acquire the allergic history. During the anesthesia period, the vital sign and the skin should be observed carefully. PMID:26474637

    We have developed an anesthesia information system (AIS) that supports the anesthesiologist in monitoring and recording during a surgical operation. In development of the system, emphasis was placed on providing an anesthesiologist-computer interface that can be adapted to typical situations during anesthesia and to individual user behavior. One main feature of this interface is the integration of the input and output of information. The only device for interaction between the anesthesiologist and the AIS is a touch-sensitive, high-resolution color display screen. The anesthesiologist enters information by touching virtual function keys displayed on the screen. A data window displays all data generated over time, such as automatically recorded vital signs, including blood pressure, heart rate, and rectal and esophageal temperatures, and manually entered variables, such as administered drugs, and ventilator settings. The information gathered by the AIS is presented on the cathode ray tube in several pages. A main distributor page gives an overall view of the content of every work page. A one-page record of the anesthesia is automatically plotted on a multicolor digital plotter during the operation. An example of the use of the AIS is presented from a field test of the system during which it was evaluated in the operating room without interfering with the ongoing operation. Medical staff who used the AIS imitated the anesthesiologist's recording and information search behavior but did not have responsibility for the conduct of the anesthetic.

    Full Text Available The purpose of this study was to determine if differences in behavior exist following dental treatment under hospital-based general anesthesia (HBGA or office-based general anesthesia (OBGA in the percentage of patients exhibiting positive behavior and in the mean Frankl scores at recall visits. This retrospective study examined records of a pediatric dental office over a 4 year period. Patients presenting before 48 months of age for an initial exam who were diagnosed with early childhood caries were included in the study. Following an initial exam, patients were treated under HBGA or OBGA. Patients were followed to determine their behavior at 6-, 12- and 18-month recall appointments. Fifty-four patients received treatment under HBGA and 26 were treated under OBGA. OBGA patients were significantly more likely to exhibit positive behavior at the 6- and 12-month recall visits p = 0.038 & p = 0.029. Clinicians should consider future behavior when determining general anesthesia treatment modalities in children with early childhood caries presenting to their office.

    Full Text Available Background and Objective: With consideration the daily increased development of outpatient surgeries and high rate of these surgeries in elderly patients, rapid and safe recovery of patients is necessary. In this clinical trial study, recovery time and nausea and vomiting after the use of two rapid-onset narcotics, Alfentanil and Remifentanil, in elderly patients were evaluated. Methods: In this double-blind prospective clinical trial, 40 elderly patients (age above 65 years candidate to cataract surgery with general anesthesia were studied. The patients were divided randomly into two groups and for first group, 10 μg/kg of Alfentanil was injected and for second group Remifentanil 0.5 μg/kg was injected intravenously during 30 seconds one minute before induction. Both two groups were under general anesthesia with same method and during the anesthesia, first group took infusion of Alfentanil 1 μg/kg/min and second group took Remifentanil 0.1 μg/kg/min. In the end of surgery, the time intervals between end of anesthesia drug administration and spontaneous respiration, eyes opening with stimulation, verbal response and discharge of recovery room, also the incidence of complications related to narcotic drugs, especially nausea and vomiting, was recorded. The data were analyzed in SPSS software using descriptive and analytical statistics such as T-test and chi square test. Results: The time of spontaneous respiration in Alfentanil group was 2 minutes and in Remifentanil group was 3.3 minutes, the difference was not statistically significant (P=0.08. The time of eyes opening with stimulation, verbal response, and discharge of recovery room were not significantly different. During recovery, incidence of nausea and vomiting in Remifentanil group (30% of patients was significantly more than Alfentanil group (5% of patients (P=0.045.

Primary lateral sclerosis (PLS is a rare idiopathic neurodegenerative disorder affecting upper motor neurons and characterized by spasticity, muscle weakness, and bulbar involvement. It can sometimes mimic early stage of more common and fatal amyotrophic lateral sclerosis (ALS. Surgical patients with a history of neurodegenerative disorders, including PLS, may be at increased risk for general anesthesia related ventilatory depression and postoperative respiratory complications, abnormal response to muscle relaxants, and sensitivity to opioids, sedatives, and local anesthetics. We present a case of a patient with PLS and recent diagnosis of breast cancer who underwent a simple mastectomy surgery uneventfully under an ultrasound guided thoracic paravertebral block, multimodal analgesia, and monitored anesthesia care. Patient reported minimal to no pain or discomfort in the postoperative period and received no opioids for pain management before being discharged home. In patients with PLS, thoracic paravertebral block and multimodal analgesia can provide reliable anesthesia and effective analgesia for breast surgery with avoidance of potential risks associated with general anesthesia, muscle paralysis, and opioid use.

    Purpose: Repetitive sedation/anesthesia (S/A) for children receiving fractionated radiation therapy requires induction and recovery daily for several weeks. In the vast majority of cases, this is accomplished in an academic center with direct access to pediatric faculty and facilities in case of an emergency. Proton radiation therapy centers are more frequently free-standing facilities at some distance from specialized pediatric care. This poses a potential dilemma in the case of children requiring anesthesia. Methods and Materials: The records of the Indiana University Health Proton Therapy Center were reviewed for patients requiring anesthesia during proton beam therapy (PBT) between June 1, 2008, and April 12, 2012. Results: A total of 138 children received daily anesthesia during this period. A median of 30 fractions (range, 1-49) was delivered over a median of 43 days (range, 1-74) for a total of 4045 sedation/anesthesia procedures. Three events (0.0074%) occurred, 1 fall from a gurney during anesthesia recovery and 2 aspiration events requiring emergency department evaluation. All 3 children did well. One aspiration patient needed admission to the hospital and mechanical ventilation support. The other patient returned the next day for treatment without issue. The patient who fell was not injured. No patient required cessation of therapy. Conclusions: This is the largest reported series of repetitive pediatric anesthesia in radiation therapy, and the only available data from the proton environment. Strict adherence to rigorous protocols and a well-trained team can safely deliver daily sedation/anesthesia in free-standing proton centers.

    Full Text Available Intravenous injection of anesthetic drugs dates back to the 17th Century when opium and chloral hydrate have been injected intravenously. It was not until the 1930s intravenous anesthesia became popular with the invention of barbiturates.Early intravenous anesthetic agents such as barbiturates were ideal for induction of anesthesia, but not suitable for maintenance of anesthesia. Most of these drugs accumulated significantly with increasing durations of infusion and also resulted in cardiorespiratory depression. The invention of propofol and shorter acting opioid analgesics such as remifentanil and alfentanil have revolutionized intravenous anesthesia. The rapid onset and offset of these drugs lends itself to being suitable agents for maintenance of anesthesia over prolonged periods of time. Detailed understanding of the pharmacokinetics of propofol and remifentanil, combined with technological advances in intravenous pumps capable of accurate delivery of drugs have resulted in great development of the field of total intravenous anesthesia and target controlled infusions. I would like to discuss, in this article, the pharmacokinetics and pharmacokinetic models behind these intravenous infusion pumps. [Int J Basic Clin Pharmacol 2014; 3(3.000: 417-423

    Representative inhalant anesthetic agent, isoflurane is commonly used during surgery in rats. However, isoflurane mediates relatively strong respiratory depression. In human and veterinary medicine, sedatives and analgesics are co-administered to complement the anesthetic action of inhalant anesthesia. The present study aimed to establish the novel balanced anesthesia that combines midazolam and butorphanol with isoflurane (MBI) in rats. Male Sprague Dawley rats were divided into 2 groups, and administered either isoflurane monoanesthesia or isoflurane with midazolam (2.5 mg/kg, ip) and butorphanol (2.0 mg/kg, ip). The minimum alveolar concentration (MAC) in each group was evaluated. Induction and recovery times were measured in each group. Adverse reactions during induction were also recorded. In each group, vital signs were assessed for 1 h under 1.5×MAC of isoflurane. Instability of vital signs was assessed under each anesthesia by calculating coefficient of variance. Compared with isoflurane monoanesthesia, MBI anesthesia caused 32% MAC reduction (isoflurane monoanesthesia: 1.30 ± 0.09%, MBI 0.87 ± 0.08%, PMBI anesthesia resulted in a relatively stable respiratory rate without decreases in SPO2 during the anesthetic period. In summary, MB premedication is effective for attenuating respiratory depression induced by isoflurane, and achieving smooth induction. This anesthetic protocol serves as a novel option for appropriate anesthesia in rats. PMID:26876437

    Today's practice of medicine involves ever more complex patients whose care is coordinated with multidisciplinary teams. Caring for these patients can challenge all members of the health care team. Sedation/anesthesia in infants/toddlers as well as uncooperative or intellectually or emotionally impaired children who require imaging studies of the chest are ongoing challenges. High-quality computed tomography (CT) chest imaging studies in children under general anesthesia are extremely important for accurate interpretation and subsequent medical decision-making. Anesthesia-induced atelectasis may obscure or mimic true pathology creating a significant quality issue. Obtaining a high-quality, motion-free chest imaging study in infants and children under general anesthesia remains a difficult task in many institutions. Meticulous attention to anesthesia and imaging techniques and specialized knowledge are required to properly perform and interpret chest imaging studies. In this commentary, we discuss the continuous struggle to obtain high-quality CT chest imaging under general anesthesia. We will also discuss the major concerns of the anesthesiologist, radiologist and pulmonologist and why cooperation and coordination among these providers are critical for an optimal quality study.

    The re-establishment of conscious awareness after discontinuing general anesthesia has often been assumed to be the inverse of loss of consciousness. This is despite the obvious asymmetry in the initiation and termination of natural sleep. In order to characterize the restoration of consciousness after surgery, we recorded frontal electroencephalograph (EEG) from 100 patients in the operating room during maintenance and emergence from general anesthesia. We have defined, for the first time, 4 steady-state patterns of anesthetic maintenance based on the relative EEG power in the slow-wave (awareness after drug discontinuation. Moreover, these emergence patterns could be broadly grouped according to the duration and rapidity of transitions amongst these slow-wave dominated brain states that precede awakening. Most patients progressed gradually from a pattern characterized by strong peaks of delta (0.5-4 Hz) and alpha/spindle (8-14 Hz) power ('Slow-Wave Anesthesia') to a state marked by low delta-spindle power ('Non Slow-Wave Anesthesia') before awakening. However, 31% of patients transitioned abruptly from Slow-Wave Anesthesia to waking; they were also more likely to express pain in the post-operative period. Our results, based on sleep-staging classification, provide the first systematized nomenclature for tracking brain states under general anesthesia from maintenance to emergence, and suggest that these transitions may correlate with post-operative outcomes such as pain.

    The aim of the study was to examine intraocular pressure (IOP) changes during laparoscopic cholecystectomy performed under either desflurane-thiopental anesthesia or propofol total intravenous anesthesia (TIVA). 36 patients who will undergo elective laparoscopic cholecystectomy were enrolled in the study. The patients were randomly divided into one of two groups: desflurane (Group D, n=18) or propofol (Group P, n=18). All patients received fentanyl 2 micro/kg IV, and then breathed 100% oxygen for 3 minutes prior to induction of anesthesia. Anesthesia was induced by using thiopental 5 mg/kg IV in Group D and 2 mg/kg IV propofol in group P. Neuromuscular block was achieved with rocuronium 0.6 mg/kg IV. Anesthesia was maintained with desflurane 3-6% in group D and propofol infusion 5-10 mg/kg/h in group P. Desflurane and propofol concentrations were adjusted to maintain mean arterial pressure witihin 20% of the preinduction value. During anaesthesia, fractionated doses of fentanyl 0.5-1 micro g /kg IV and maintenance doses of muscle relaxants were used. In both groups, the the mixture 60% nitrous oxide and 40% oxygen was administered used. Arterial pressure, heart rate, ETCO2, SpO2 and IOP were recorded at the predefined time points. Creation of pneumoperitoneum resulted in a significant increase in IOP which remained elevated throughout the operation in both groups. Also, we recorded a similar IOP changes with both techniques except at five minutes after pneumoperitoneum in 15 degrees reverse Trendelenburg position during desflurane-thiopental anesthesia. In c6nclusion, desflurane-thiopental anesthesia maintains the IOP at least at similar levels compared to propofol TIVA anesthesia.

    Full Text Available The animal models used in this study were Plexus anesthesia in frogs, Infiltration anesthesia in guinea pigs, Surface anesthesia in rabbits. The drugs were diluted with normal saline. Lignocaine2%: xylocaine hydrochloride injection IP, Bupivacaine 0.5%: Bupivacaine hydrochloride injections IP were prepared. Plexus anesthesia: Frog was pithed and spinal cord was destroyed up to the 3 vertebra. The abdominal pouch was filled with local anesthetic solution. Reflex activity was tested by immersing both feet of the frog every two minutes for not longer than 10 seconds into N/10 Hydrochloric acid. The time was noted. Surface anesthesia: Albino rabbits of either sex weighing 2.5 – 3.0kg ware selected. The conjunctival sac of one eye was held open, thus formed a pouch. 0.5ml of solution of the anesthetic was applied into the conjunctival sac for 30 sec. Infiltration anesthesia: Preparation of guinea pig: Guinea pigs (either sex weighing 250-300grams were used. Lignocaine produced rapid onset of plexus anesthesia in Frogs in comparison to the bupivacaine at concentration of 0.1% & 0.2% which is statistically significant. Bupivacaine is more potent than the lignocaine as a surface anesthetic agent in the Rabbit, where as lignocaine could produce surface anesthesia at concentration of 0.5% or 0.1% or both. Both bupivacaine and lignocaine produced infiltration anesthesia on intradermal injection in guinea pigs but the duration of infiltration anesthesia produced by bupivacaine is more prolonged which is statistically significant in comparison to the lignocaine at all the three concentrations tested i.e. 0.05%, 0.1% & 0.2%.

    The beginnings of modern anesthetic equipment date back to Morton's inhalation flagon in 1846. The numerous devices developed and introduced subsequently can be divided into four groups: 1. Simple ether and chloroform masks for open inhalation anesthesia, from Simpson (1847) to Brown (1928). 2. Vapour inhalators according to the "draw over" principle of Snow (1847) up to the Oxford vaporizer (1941). 3. Closed or half-closed inhalation equipment for ether or chloroform with to and fro breathing, from Clover (1877) to Ombredanne (1908). 4. Equipment for anaesthesia with nitrous oxide. From 1868 onwards this led to the incorporation of gas bottles in anaesthetic equipment and between 1885 and 1890 to the construction of mixing-valves for nitrous oxide and oxygen. In addition, reducing valves, flow meters and vaporizers were developed. The first anaesthetic apparatus with circle system and CO2-absorber was constructed in 1925 by the Dräger factory in Lübeck. Sudeck and Schmidt introduced this technique of anaesthesia in the university hospital of Hamburg-Eppendorf between 1920 and 1925. PMID:6758628

    Full Text Available Information overload of the anesthesiologist through technological advances have threatened the safety of patients under anesthesia in the operating room (OR. Traditional monitoring and alarm systems provide independent, spatially distributed indices of patient physiological state. This creates the potential to distract caregivers from direct patient care tasks. To address this situation, a novel reactive agent decision support system with graphical human machine interface was developed. The system integrates the disparate data sources available in the operating room, passes the data though a decision matrix comprising a deterministic physiologic rule base established through medical research. Patient care is improved by effecting change to the care environment by displaying risk factors and alerts as an intuitive color coded animation. The system presents a unified, contextually appropriate snapshot of the patient state including current and potential risk factors, and alerts of critical patient events to the operating room team without requiring any user intervention. To validate the efficacy of the system, a retrospective analysis focusing on the hypotension rules were performed. Results show that even with vigilant and highly trained clinicians, deviations from ideal patient care exist and it is here that the proposed system may allow more standardized and improved patient care and potentially outcomes.

    Full Text Available Introduction. Intravenous regional anesthesia (IVRA is one of the successful method of anesthesia in relief of pain of surgery. It has a multiple advantages including feasibility, rapidity of recovery, rapid onest, muscular relaxation and controllable onset of anesthesia. But this technique dose not relief postoperative pain. In the previous studies it had been tried to add some drugs to local anesthetic in IVRA for relief postoperative pain. Methods. One hundred and ten adult patients in class I and II ASA scheduled for elective operation of unilatral upper extrimeties under IVRA, randomly allocated into interventional and control groups. NRA was done with Lidocaine 0.5 percent with or without dexamethason. Postoperative pain was assessed by visual analogue scale. Results. Addition of dexamethason to local anesthetic in IVRA resulted in better tolleration of turniquate pain and reduced VAS score. Frequency of severe postoperative pain was reduced in case group. Discussion. It seems that dexamethason usage in local anesthetic in IVRA prevents sever postoperative pain in patients. The results of this study is simillar to the study wich added ketorolac to IVRA solution.

    Full Text Available Sirish Kondabolu, Rishimani Adsumelli, Joy Schabel, Peter Glass, Srinivas PentyalaDepartment of Anesthesiology, School of Medicine, Stony Brook Medical Center, Stony Brook, New York, USABackground: It is accepted that there is a severe risk of dural puncture in epidural anesthesia. Of major concern to anesthesiologists is unintentional spinal block. Reliable identification of cerebrospinal fluid (CSF from the aspirate is crucial for safe epidural anesthesia. The aim of this study was to determine whether prostaglandin D2 could be clinically used as a marker for the detection of CSF traces.Methods: After obtaining Institutional Review Board approval and patient consent, CSF was obtained from patients undergoing spinal anesthesia, and blood, urine, and saliva were obtained from normal subjects and analyzed for prostaglandin D2 (PGD. CSF (n=5 samples were diluted with local anesthetic (bupivacaine, normal saline and blood in the ratios of 1:5 and 1:10. PGD levels in the CSF samples were analyzed with a PGD-Methoxime (MOX EIA Kit (Cayman Chemicals, MI. This assay is based on the conversion of PGD to a stable derivative, which is analyzed with antiserum specific for PGD-MOX. Results: Different concentrations of pure PGD-MOX conjugate were analyzed by EIA and a standard curve was derived. PGD levels in CSF and CSF with diluents were determined and the values were extrapolated onto the standard curve. Our results show a well-defined correlation for the presence of PGD both in straight CSF samples and in diluted CSF (dilution factor of 1:5 and 1:10. Conclusion: Prostaglandin D2 was reliably identified in CSF by enzyme-linked immunosorbent assay when diluted with local anesthetic, saline, and serum, and can be used as a marker to identify the presence of CSF in epidural aspirates.Keywords: epidural, cerebrospinal fluid, leak, marker, prostaglandin D2

    Full Text Available The re-establishment of conscious awareness after discontinuing general anesthesia has often been assumed to be the inverse of loss of consciousness. This is despite the obvious asymmetry in the initiation and termination of natural sleep. In order to characterize the restoration of consciousness after surgery, we recorded frontal electroencephalograph (EEG from 100 patients in the operating room during maintenance and emergence from general anesthesia. We have defined, for the first time, 4 steady-state patterns of anesthetic maintenance based on the relative EEG power in the slow-wave (<14 Hz frequency bands that dominate sleep and anesthesia. Unlike single-drug experiments performed in healthy volunteers, we found that surgical patients exhibited greater electroencephalographic heterogeneity while re-establishing conscious awareness after drug discontinuation. Moreover, these emergence patterns could be broadly grouped according to the duration and rapidity of transitions amongst these slow-wave dominated brain states that precede awakening. Most patients progressed gradually from a pattern characterized by strong peaks of delta (0.5-4 Hz and alpha/spindle (8-14 Hz power ('Slow-Wave Anesthesia' to a state marked by low delta-spindle power ('Non Slow-Wave Anesthesia' before awakening. However, 31% of patients transitioned abruptly from Slow-Wave Anesthesia to waking; they were also more likely to express pain in the post-operative period. Our results, based on sleep-staging classification, provide the first systematized nomenclature for tracking brain states under general anesthesia from maintenance to emergence, and suggest that these transitions may correlate with post-operative outcomes such as pain.

    Background Surgical stress causes a helper T-cell type 2 (Th2)-dominant status and disturbs the Th1/Th2 cytokine balance. Anesthesia can suppress the stress response to surgery, therefore it may inhibit the imbalance in the Th1/Th2 ratio. In this study, we assessed if propofol anesthesia and sevoflurane anesthesia influence the Th1/Th2 cytokine balance, and which anesthesia method better attenuates this ratio.Methods Twenty-eight patients with an American Society of Anesthesiologists (ASA) physical status of I undergoing laparoscopic cholecystectomy were selected. They were randomly allocated into two groups of 14. Group 1 received propofol anesthesia by a target-controlled-infusion (TCI) pump and group 2 received sevoflurane anesthesia.Non-invasive blood pressure, heart rate, and end-expiration CO2 partial pressure were monitored during anesthesia. The depth of anesthesia was measured using the bispectral index (BIS), and maintained between 50 and 60. During surgery we adjusted the doses of propofol and sevoflurane according to the BIS. Samples of peripheral blood were taken before the induction of anesthesia (T1), after the induction of anesthesia (T2), at the beginning of surgery (T3), at the end of surgery (T4) and on the first day after surgery (D1). Blood samples were analyzed to give the Th1/Th2 ratio and plasma level of cortisol.Results Non-invasive blood pressure, heart rate and end-expiration CO2 partial pressure were not notably different in the two groups. At T4, the percentage of T1 cells was higher in group 1 and had statistical significance (P <0.05). The percentage of T2 cells was not significantly different in the two groups. At T4, the difference in the Th1/Th2 ratio was significantly different. At T3, T4, and D1, the plasma level of cortisol was lower in group 1(P <0.05).Conclusion Compared with sevoflurane, propofol can preferably promote Th cells to differentiate into Th1 cells and inhibit surgical stress. Propofol may therefore be

    This study follows the evolution of anesthesia in gynecology and obstetrics in Spain between 1916 and 1936. Research included revising all articles and references concerning anesthesiology appearing in the Revista Española de Obstetricia y Ginecologia over the 20 years during which that journal was published. Eighty-three articles were found: 18 (21.6%) original research reports, 37 (44.6%) reviews of the Spanish professional literature and 28 (33.7%) summaries and descriptions of meetings of scientific organizations. Spanish references constituted 39.8% with the remaining 60.2% coming from European and Hispano-American sources. Twenty-four (34.9%) were related to spinal anesthesia, 15 (18%) covered various methods for analgesia during childbirth and 14 (16.8%) were on barbiturates. The remaining articles referred to rectally administered anesthesia, local anesthesia, inhalatory anesthesia and pain in gynecology. In conclusion, our review reveals the strong international contacts in Spanish gynecology during this period, as well as the interest of gynecologists and obstetricians in various anesthetic techniques and the rapid incorporation of new methods into their therapeutic arsenal.

    Full Text Available Aims: In our group, after a study showing that spinal anesthesia is safe when compared with general anesthesia, spinal anesthesia has been the technique of choice for this procedure. This is a prospective study with all patients undergoing LC under spinal anesthesia in our department since 2007. Settings and Design: Prospective observational. Materials and Methods: From 2007 to 2011, 369 patients with symptoms of colelithiasis, laparoscopic cholecystectomy were operated under spinal anesthesia with pneumoperitoneum and low pressure CO 2. We compared 15 mg of hyperbaric bupivacaine and lumbar puncture with 10 or 7.5 mg of hyperbaric bupivacaine thoracic puncture, all with 25 μg fentanyl until the sensory level reached T 3 . Intraoperative parameters, post-operative pain, complications, recovery, patient satisfaction, and cost were compared between both groups. Statistical Analysis Used: Means were compared by ANOVA or Kruskal-Wallis test, the percentages of the Chi-square test or Fisher′s exact test when appropriate. Time of motor and sensory block in spinal anesthesia group was compared by paired t test or Mann-Whitney test. Differences were considered significant when P ≤ 0.05, and for comparisons of mean pain visual scale, we employed the Bonferroni correction applied to be considered significant only with P ≤ 0.0125 Results: All procedures were completed under spinal anesthesia. The use of lidocaine 1% was successful in the prevention of shoulder pain in 329 (89% patients. There were significant differences in time to reach T 3 , obtaining 15 mg > 10 mg = 7.5 mg. There is a positive correlation between the dose and the incidence of hypotension. The lowest doses gave a decrease of 52.2% in the incidence of hypotension. There was a positive correlation between the dose and duration of sensory and motor block. Sensory block was almost twice the motor block at all doses. With low doses, 60% of patients went from table to stretcher

    Full Text Available Aims: To evaluate the safety and efficacy of transconjunctival 25 gauge vitrectomy under topical anesthesia. Settings and Design: A pilot study of consecutive cases which underwent 25 gauge vitrectomy under topical anesthesia. Materials and Methods: Seven eyes of 7 patients underwent 25 gauge vitrectomy under topical anesthesia with a pledget soaked in anesthetic, for vitreous hemorrhage (2 eyes, retained cortex (1 eye and postoperative endophthalmitis (4 eyes. Subjective pain and discomfort were graded from 0 (no pain or discomfort to 4 (severe pain and discomfort. Patients underwent an immediate postoperative assessment, followed by day one and one week postoperative evaluation. Results: All patients had grade 0 pain during the surgery. Five patients had grade 2 pain during the placement of the sclerotomies. None of the patients required any sedation during the procedure. No inadvertent eye movements were noted during surgery. Except one patient, none required postoperative analgesics. Five eyes had a favorable outcome. No eyes in this pilot study had any procedure-related complications. Conclusion: With appropriate case selection, topical anesthesia is a safe and effective alternative to infiltrative anesthesia for 25 gauge vitrectomy. A larger series of patients with a longer follow-up is required to validate the findings of this pilot study.

    During the administration of anesthesia, the anesthesia provider has historically created a paper record, charted manually, that included extensive patient care-related data (vital signs, other parameters, etc) and commentaries. DocuSys, a proprietary anesthesia information management system (AIMS), creates an electronic version of the anesthesia record and provides additional information. It electronically captures data from clinical monitors and other sources, including scheduling applications and laboratory computers. The AIMS facilitates chart entries such as drug doses and case narratives. Benefits of an AIMS include improved legibility of the anesthesia record and greater efficiency in documentation efforts. Use of the AIMS assists the practitioner with decision support logic, such as the timing of antibiotic administration and the inclusion of legally required documentation. Upon case completion, the AIMS data are immediately available to other information systems, such as billing and medical records. Data can be made available from a single case or, more important, from thousands of cases to analyze variables such as efficiency of services, adherence to best practices, patient outcomes, and clinical research. The AIMS was deployed at the main campus of the Ochsner Health System on March 26, 2009. In this article, we discuss the issues involved in the AIMS implementation process: the successes, surprises, and continued challenges. PMID:21734847

    Delayed awakening from anesthesia remains one of the biggest challenges that involve an anesthesiologist. With the general use of fast-acting anesthetic agents, patients usually awaken quickly in the postoperative period. The time to emerge from anesthesia is affected by patient factors, anesthetic factors, duration of surgery, and painful stimulation. The principal factors responsible for delayed awakening following anesthesia are anesthetic agents and medications used in the perioperative period. Nonpharmacological causes may have a serious sequel, hence recognizing these organic conditions is important. Certain underlying metabolic disorders such as hypoglycemia, severe hyperglycemia, and electrolyte imbalance, especially hypernatremia, hypoxia, hypercapnia, central anticholinergic syndrome, chronic hypertension, liver disease, hypoalbuminemia, uremia, and severe hypothyroidism may also be responsible for delayed recovery following anesthesia. Unexpected delayed emergence after general anesthesia may also be due to intraoperative cerebral hypoxia, hemorrhage, embolism, or thrombosis. Accurate diagnosis of the underlying cause is the key for the institution of appropriate therapy, but primary management is to maintain airway, breathing, and circulation. This comprehensive review discusses the risk factors, causes, evaluation and management of delayed recovery based on our clinical experience, and literature search on the internet, supported by the standard textbooks of anesthesiology.

  20. Non-invasive anesthesia for children undergoing proton radiation therapy

    International Nuclear Information System (INIS)

    Background: Proton therapy is a newer modality of radiotherapy during which anesthesiologists face specific challenges related to the setup and duration of treatment sessions. Purpose: Describe our anesthesia practice for children treated in a standalone proton therapy center, and report on complications encountered during anesthesia. Materials and methods: A retrospective review of anesthetic records for patients ⩽18 years of age treated with proton therapy at our institution between January 2006 and April 2013 was performed. Results: A total of 9328 anesthetics were administered to 340 children with a median age of 3.6 years (range, 0.4–14.2). The median daily anesthesia time was 47 min (range, 15–79). The average time between start of anesthesia to the start of radiotherapy was 7.2 min (range, 1–83 min). All patients received Total Intravenous Anesthesia (TIVA) with spontaneous ventilation, with 96.7% receiving supplemental oxygen by non-invasive methods. None required daily endotracheal intubation. Two episodes of bradycardia, and one episode each of; seizure, laryngospasm and bronchospasm were identified for a cumulative incidence of 0.05%. Conclusions: In this large series of children undergoing proton therapy at a freestanding center, TIVA without daily endotracheal intubation provided a safe, efficient, and less invasive option of anesthetic care

    The practice of anesthesia in war places significant restraints on the choice of anesthetic technique used; these include, but are not limited to, safety, simplicity, and portability. Ever since intravenous anesthesia became a practical alternative, there have been military doctors who felt that this technique was particularly suited to this environment. The challenge, as in civilian practice, has been to find the appropriate drugs as well as simple and safe delivery systems. The urgency of war has always stimulated innovation in medicine to counteract the ongoing development of weapons of war and their effects on the human body and to achieve improved survival as public expectations rise. This article traces the development of and the use of intravenous anesthesia by military physicians for battle casualties. The story starts long before the era of modern anesthesia, and the discussion concludes in the dog days of the cold war. The rapidly increasing interest in intravenous anesthesia in both civilian and military practice since the early 1990s is left for other authors to examine.

    Although we describe a clinical situation that most likely occurs in hundreds of operatory rooms in the world, we report this case as provocation. It concerns an unexpected awakening from an appropriate depth of anesthesia, although the BIS monitor showed a BIS index of less than 50 for a prolonged period before and after the event. Approximately 30 min after induction of anesthesia, the patient had a hypothetic sudden arousal of consciousness, with spontaneous movements, facial muscle activation, intolerance to the tracheal tube, and tearing. After immediate intravenous administration of midazolam (4 mg), the patient returned to a depth of anesthesia status, and surgery was completed uneventfully. The patient had no recall of the event when questioned during the episode, at emergence, or at 24 h, 36 h, and 7 days after surgery. Were these events spinal reflexes to pain or stimulation although the cortex was still anesthetized? Maybe this is the more rational explanation. Was the patient awake but not aware? Is it possible that our patient experienced only a transient arousal from consciousness, and that he did not have recall because the arousal time was short and we blocked memory consolidation? The latter hypothesis provides an opportunity to discuss the evidence that at the moment there is no device to assess the depth of anesthesia. We also focus on the possibility of interfering with memory processing under anesthesia. PMID:26671259

    Lessons learned over the past decade and a half of combat casualty management has brought about numerous advances in trauma anesthesia practice. In the post-Vietnam era, deployable anesthesia equipment centered on the capability to provide a balanced anesthetic technique, utilizing a combination of volatile gas and intravenous anesthetic adjuncts. The evolution of the modern battlefield has forced anesthesia providers across the military to adapt to mission requirements that often dictate a surgical capability that is more rapidly mobile and less reliant on logistical support. Institutional medical equipment development has focused on fielding a lighter, more mobile volatile gas delivery method. Despite numerous advances in anesthetic gas delivery, many veteran anesthesia providers have come to recognize the value of alternative anesthetic techniques in the deployed setting. One of the most appealing advances in combat anesthesia practice is the emergence of total intravenous anesthetics (TIVA) for trauma management and resuscitation. Although there have been numerous developments in anesthetic equipment for use in the deployed setting, TIVA has many advantages over volatile gas administration. Future research, development, and education should focus on TIVA and the ability to provide this as an alternative safe anesthetic for patients in austere environments. It is imperative to retain the lessons we have learned in order to adapt more effectively in future conflicts. This accumulation of knowledge must inform future innovative solutions to the challenges of casualty management in a deployed setting.

    Full Text Available Background and the purpose of the study: Opioids are usually used in regional anesthesia, with or without local anesthetics to improve the regional block or postoperative pain control. Since no data are available on fentanyl's effect on the onset time of lidocaine interscalene anesthesia, the purpose of this study was to examine its effect on the onset time of sensory and motor blockade during interscalene anesthesia.  Methods: In a prospective, randomized, double-blind study, ninety patients scheduled for elective shoulder, arm and forearm surgeries under an  interscalene brachial plexus block .They were randomly allocated to receive either 30 ml of  1.5 % lidocaine with 1.5 ml of isotonic saline  (control group, n = 39 or 30 ml of 1.5%  lidocaine with 1.5 ml (75µg of  fentanyl (fentanyl group,n=41. Then the onset time of sensory and motor blockades of the shoulder, arm and forearm were evaluated every 60 sec. The onset time of the sensory and motor blockades was defined as the time between the last injection and the total abolition of the pinprick response and complete paralysis. The duration of sensory blocks were considered as the time interval between the administration of the local anesthetic and the first postoperative pain sensation. Results: Ten patients were excluded because of unsuccessful blockade or unbearable pain during the surgery. The onset time of the sensory block was significantly faster in the fentanyl group (186.54± 62.71sec compared with the control group (289.51± 81.22, P < 0.01. The onset times of the motor block up to complete paralysis in forearm flexion was significantly faster in the fentanyl group (260.61± 119.91sec than the control group (367.08± 162.43sec, P < 0.01 There was no difference in the duration of the sensory block between two groups. Conclusion: Results of the study showed that the combination of 75 µg fentanyl and 1.5% lidocaine solution accelerated the onset of sensory and motor

    AIM: To summarize the effects of laparoscopic ethanol injection and radiofrequency ablation (L-EI-RFA), thora-coscopic (T-EI-RFA) and open-surgery assisted EI-RFA (O-EI-RFA) under general anesthesia for the treatment of hepatocellular carcinoma (HCC).METHODS: Time-lag performance of RFA after ethanol injection (Time-lag PEI-RFA) was performed in all cases. The volume of coagulated necrosis and the applied energy for total and per unit volume coagulated necrosis were examined in the groups treated under general (group G) or local anesthesia (group L).RESULTS: The results showed that the total applied energy and the applied energy per unit volume of whole and marginal, coagulated necrosis were significantly larger in group G than those in the group L, resulting in a larger volume of coagulated necrosis in the group G. The rate of local tumor recurrence within one year was extremely low in group G.CONCLUSION: These results suggest that EI-RFA, under general anesthesia, may be effective for the treatment of HCC because a larger quantity of ethanol and energy could be applied during treatment under pain-free condition for the patients.

  10. Laser-Assisted Periodontal Management of Drug-Induced Gingival Overgrowth under General Anesthesia: A Viable Option

    2013-01-01

    Full Text Available Gingival overgrowth/hyperplasia can be attributed to several causes, but drug-induced gingival overgrowth/hyperplasia arises secondarily to prolonged use of antihypertensive drugs, anticonvulsants and immunosuppressants. The management is complex in nature considering the multitude of factors involved such as substitution of drug strict plaque control along with excision of the tissue to be performed under local anesthesia as outpatient. In the recent times, the patient’s psychological fear of the treatment with the use of surgical blade and multiple visits has developed the concept of single visit treatment under general anesthesia incorporating a laser as viable option. The present case highlights the new method of management of gingival overgrowth.

    The depth of anesthesia quantification has been one of the most research interests in the field of EEG signal processing and nonlinear dynamical analysis has emerged as a novel method for the study of complex systems in the past few decades. In this investigation we use the concept of nonlinear time series analysis techniques to reconstruct the attractor of anesthesia from EEG signal which have been obtained from different hypnotic states during surgery to give a characterization of the dimensional complexity of EEG by Correlation Dimension estimation. The dimension of the anesthesia strange attractor can be thought of as a measure of the degrees of freedom or the ;complexity' of the dynamics at different hypnotic levels. The results imply that for awaked state the correlation dimension is high, On the other hand, for light, moderate and deep hypnotic states these values decrease respectively; which means for anesthetized situation we expect lower correlation dimension.

    2016-02-01

    Total knee arthroplasty is associated with substantial postoperative pain that may impair mobility, reduce the ability to participate in rehabilitation, lead to chronic pain, and reduce patient satisfaction. Traditional general anesthesia with postoperative epidural and patient-controlled opioid analgesia is associated with an undesirable adverse-effect profile, including postoperative nausea and vomiting, hypotension, urinary retention, respiratory depression, delirium, and an increased infection rate. Multimodal anesthesia--incorporating elements of preemptive analgesia, neuraxial perioperative anesthesia, peripheral nerve blockade, periarticular injections, and multimodal oral opioid and nonopioid medications during the perioperative and postoperative periods--can provide superior pain control while minimizing opioid-related adverse effects, improving patient satisfaction, and reducing the risk of postoperative complications.

    A modified technique is described for iontophoretic anesthesia in children who require myringotomy and insertion of a tube (tympanostomy). Principal modifications include the following procedures: (1) preoperative parenteral sedation; (2) relatively painless injection of lidocaine hydrochloride-epinephrine hydrochloride solution into the external auditory canal skin after iontophoresis alone to eliminate the extreme bony canal wall tenderness; (3) injection of lidocaine-epinephrine solution into an atelectatic middle ear to anesthetize the promontory for painless tube insertion; (4) substitution of a disposable ECG electrode for a metal plate electrode to eliminate the possibility of electrical burn from metal-to-skin contact. These modifications enhance the effectiveness and the safety of iontophoretic anesthesia, minimize the need for general anesthesia, and liberalize the indications for tympanostomy.

    Xylazine and ketamine are an anesthetic combination used in feline practice for routine surgical procedures. In a controlled study, we evaluated the effects of yohimbine, an antagonist of xylazine, on the anesthesia induced by this anesthetic combination in cats. Two intramuscular doses of xylazine and ketamine (2.2 mg of xylazine/kg plus 6.6 mg of ketamine/kg and 4.4 mg of xylazine/kg plus 6.6 mg of ketamine/kg) caused approximately 60 and 100 minutes of anesthesia, respectively, in control cats. When yohimbine (0.1 mg/kg) was given intravenously 45 minutes after ketamine administration, the cats regained consciousness within 3 minutes. They were ambulatory 1 to 2 minutes after regaining consciousness. Yohimbine also reversed the bradycardia and respiratory depression elicited by xylazine-ketamine. The results indicated that yohimbine may be useful for controlling the duration of xylazine-ketamine anesthesia in cats. PMID:6501048

    Anesthesia Information Management Systems (AIMS) display and archive perioperative physiological data and patient information. Although currently in limited use, the potential benefits of an AIMS with regard to enhancement of patient safety, clinical effectiveness and quality improvement, charge capture and professional fee billing, regulatory compliance, and anesthesia outcomes research are great. The processes and precautions appropriate for AIMS selection, installation, and implementation are complex, however, and have been learned at each site by trial and error. This collaborative effort summarizes essential considerations for successful AIMS implementation, including product evaluation, assessment of information technology needs, resource availability, leadership roles, and training.

    Full Text Available General anesthetics are used during medical and surgical procedures to reversibly induce a state of total unconsciousness in patients. Here, we investigate, from a dynamic network perspective, how the cortical and cardiovascular systems behave during anesthesia by applying nonparametric spectral techniques to cortical electroencephalography, electrocardiogram and respiratory signals recorded from anesthetized rats under two drugs, ketamine-xylazine (KX and pentobarbital (PB. We find that the patterns of low-frequency cortico-cardio-respiratory network interactions may undergo significant changes in network activity strengths and in number of network links at different depths of anesthesia dependent upon anesthetics used.

    Background. Laparoscopic cholecystectomy is usually carried out under general anesthesia. There were a few studies which have found spinal anesthesia as a safe alternative. We aimed to evaluate the postoperative events between spinal anesthesia and general anesthesia in patients undergoing laparoscopic cholecystectomy. Methods. We searched PubMed, Embase, and Cochrane Library (from inception to January 2016) for eligible studies. The primary outcome was the visual analogue scale score. Secondary outcomes included postoperative nausea and vomiting and urine retention 24 hours postoperatively. We calculated pooled risk ratios and 95% confidence interval using random- or fixed-effects models. Results. Eight trials involving 723 patients were listed. Meta-analysis showed that patients in spinal anesthesia groups have lower visual analogue scale score 24 hours postoperatively. There were significant decreases in the occurrence of postoperative nausea and vomiting in spinal anesthesia group when compared with general anesthesia group (odds ratios: 0.38, 95% confidence interval: 0.19–0.76; P = 0.006) with heterogeneity accepted (I2 = 13%; P = 0.33), while urine retention rate was increased in patients with spinal anesthesia (odds ratios: 4.95, 95% confidence interval: 1.24–19.71; P = 0.02) without any heterogeneity (I2 = 0%; P = 0.98). Conclusions. Spinal anesthesia may be associated with less postoperative pain and postoperative nausea and vomiting compared with general anesthesia. PMID:27525282

    Creation of the American Society of Anesthesiologists Committee on Geriatric Anesthesia provided an opportunity for individuals to interact, strategize, and work with medical organizations outside of anesthesiology. These opportunities expanded with creation of the Society for the Advancement of Geriatric Anesthesia. The American Geriatrics Society provided a major boost when they realized it was important for surgical and related specialties to take an active role in the care of older patients. From this have come educational grants to improve residency training and establishment of a major research grant program now managed by the National Institutes of Health. Nevertheless, for improved care of the older patient, the level of involvement has to increase.

    Full Text Available Background: The role of the anesthesiologist is often unknown among patients. But, the situation where the anesthesiologist is uncertain of his/her function gives more cause for concern. Methods: A questionnaire survey on the appraisal of anesthetic practices was carried out over 5 months using the style of clinical practice. Results: One-third of the anesthesiologists who responded to the survey attached little importance to the work they did by not communicating the same to their patients while 45.2% did not discuss the intraoperative findings with the surgeons. Although 57 (59.4% of the respondents usually visit their patients on the ward preoperatively, only 16 (21.6% discussed the proposed anesthetic procedure with the patients. Thirty-nine (40.2% respondents claimed that they do not wear ward coats to the ward at the preoperative visit. Less than 20% consistently conducted a postoperative visit. The majority of the respondents would treat all patients as important, irrespective of social status, while 74.5% of them considered obtaining informed consent for anesthesia from patients as significantly important. Conclusion: The current practice of anesthesia has been found wanting in several aspects. Knowledgeable discussion by anesthesiologists with surgeons as well as enlightenment of patients and their relatives about their work will improve the quality of anesthesia care remarkably. Changes in the anesthesia training curriculum to reflect these deficiencies would be helpful.

  8. Inverse zombies, anesthesia awareness, and the hard problem of unconsciousness.

    Philosophical (p-) zombies are constructs that possess all of the behavioral features and responses of a sentient human being, yet are not conscious. P-zombies are intimately linked to the hard problem of consciousness and have been invoked as arguments against physicalist approaches. But what if we were to invert the characteristics of p-zombies? Such an inverse (i-) zombie would possess all of the behavioral features and responses of an insensate being, yet would nonetheless be conscious. While p-zombies are logically possible but naturally improbable, an approximation of i-zombies actually exists: individuals experiencing what is referred to as "anesthesia awareness." Patients under general anesthesia may be intubated (preventing speech), paralyzed (preventing movement), and narcotized (minimizing response to nociceptive stimuli). Thus, they appear--and typically are--unconscious. In 1-2 cases/1000, however, patients may be aware of intraoperative events, sometimes without any objective indices. Furthermore, a much higher percentage of patients (22% in a recent study) may have the subjective experience of dreaming during general anesthesia. P-zombies confront us with the hard problem of consciousness--how do we explain the presence of qualia? I-zombies present a more practical problem--how do we detect the presence of qualia? The current investigation compares p-zombies to i-zombies and explores the "hard problem" of unconsciousness with a focus on anesthesia awareness. PMID:18635380

As interest in performing increasingly complex surgical procedures on an outpatient basis continues to grow, the surgeon and anesthesiologist alike must be prepared to offer safe and reliable anesthesia and analgesia in the ambulatory setting. Surgeons must be aware of the possible techniques that will be employed in their surgeries in order to anticipate and prepare patients for possible postoperative side effects, and anesthesiologists must be prepared to offer such techniques in order to ensure a relatively rapid return to normal activity despite potentially having undergone major surgery. The following is a review of the specific considerations that should be given to ambulatory plastic surgery patients with comments on recent developments in the techniques used to safely administer agreeable and effective anesthesia.

    Full Text Available Ushma Shah, David T Wong, Jean Wong Department of Anesthesia, Toronto Western Hospital, University Health Network, University of Toronto, Toronto, ON, Canada Abstract: Most surgeries in North America are performed on an ambulatory basis, reducing health care costs and increasing patient comfort. Patient satisfaction is an important outcome indicator of the quality of health care services incorporated by the American Society of Anesthesiologists (ASA. Patient satisfaction is a complex concept that is influenced by multiple factors. A patient's viewpoint and knowledge plays an influential role in patient satisfaction with ambulatory surgery. Medical optimization and psychological preparation of the patient plays a pivotal role in the success of ambulatory surgery. Postoperative pain, nausea, and vomiting are the most important symptoms for the patient and can be addressed by multimodal drug regimens. Shared decision making, patient–provider relationship, communication, and continuity of care form the main pillars of patient satisfaction. Various psychometrically developed instruments are available to measure patient satisfaction, such as the Iowa Satisfaction with Anesthesia Scale and Evaluation du Vecu de I'Anesthesie Generale, but none have been developed specifically for ambulatory surgery. The ASA has made recommendations for data collection for patient satisfaction surveys and emphasized the importance of reporting the data to the Anesthesia Quality Institute. Future research is warranted to develop a validated tool to measure patient satisfaction in ambulatory surgery. Keywords: patient, satisfaction, anesthesia, outcomes, questionnaire, perspectives

    Full Text Available The evolution of techniques and knowledge of beating heart surgery has led anesthesia toward the development of new procedures and innovations to promote patient safety and ensure high standards of care. Off-pump coronary artery bypass (OPCAB surgery has shown to have some advantages compared to on-pump cardiac surgery, particularly the reduction of postoperative complications including systemic inflammation, myocardial injury, and cerebral injury. Minimally invasive surgery for single vessel OPCAB through a limited thoracotomy incision can offer the advantage of further reduction of complications. The anesthesiologist has to deal with different issues, including hemodynamic instability and myocardial ischemia during aorto-coronary bypass grafting. The anesthesiologist and surgeon should collaborate and plan the best perioperative strategy to provide optimal care and ensure a rapid and complete recovery. The use of high thoracic epidural analgesia and fast-track anesthesia offers particular benefits in beating heart surgery. The excellent analgesia, the ability to reduce myocardial oxygen consumption, and the good hemodynamic stability make high thoracic epidural analgesia an interesting technique. New scenarios are entering in cardiac anesthesia: ultra-fast-track anesthesia with extubation in the operating room and awake surgery tend to be less invasive, but can only be performed on selected patients.

    Outcome analysis is essential to health care quality improvement efforts. Pediatric anesthesia faces unique challenges in analyzing outcomes. Anesthesia most often involves a one-time point of care interaction where work flow precludes detailed feedback to care givers. In addition, pediatric outcome evaluations must take into account patients' age, development, and underlying illnesses when attempting to establish benchmarks. The deployment of electronic medical records, including preoperative, operative, and postoperative data, offers an opportunity for creating datasets large and inclusive enough to overcome these potential confounders. At our institution, perioperative data exist in five distinct environments. In this study, we describe a method to integrate these datasets into a single web-based relational database that provides researchers and clinicians with regular anesthesia outcome data that can be reviewed on a daily, weekly, or monthly basis. Because of its complexity, the project also entailed the creation of a 'dashboard,' allowing tracking of data trends and rapid feedback of measured metrics to promote and sustain improvements. We present the first use of such a database and dashboard for pediatric anesthesia professionals as well as successfully demonstrating its capabilities to perform as described above. PMID:26956515

METHODS: Sixty patients (American Society of Anesthesiologists physical status I or II, aged 18-50 years, scheduled for elective minor surgical operations under spinal anesthesia with hyperbaric bupivacaine, were enrolled. They were administered saline (group C, n = 30 or dexmedetomidine (group D, n = 30. Motor block was assessed using a Modified Bromage Scale. The presence of shivering was assessed by a blinded observer after the completion of subarachnoid drug injection. RESULTS: Hypothermia was observed in 21 patients (70% in group D and in 20 patients (66.7% in group C (p = 0.781. Three patients (10% in group D and 17 patients (56.7% in group C experienced shivering (p = 0.001. The intensity of shivering was lower in group D than in group C (p = 0.001. Time from baseline to onset of shivering was 10 (5-15 min in group D and 15 (5-45 min in group C (p = 0.207. CONCLUSION: Dexmedetomidine infusion in the perioperative period significantly reduced shivering associated with spinal anesthesia during minor surgical procedures without any major adverse effect during the perioperative period. Therefore, we conclude that dexmedetomidine infusion is an effective drug for preventing shivering and providing sedation in patients during spinal anesthesia.

    Full Text Available Anesthesia in a dwarf patient may be challenging as various anatomical anomalies make both general and regional anesthesia difficult. These patients may have atlantoaxial instability, potential for airway obstruction, and associated respiratory problems that may pose problems for general anesthesia. Spinal stenosis, osteophytes, short pedicles, or a small epidural space could complicate regional anesthesia in dwarfs which could lead to difficulties in locating the epidural space and increase the risk of dural puncture. Spinal stenosis may impair cerebrospinal fluid flow such that identification of dural puncture is difficult. This elderly dwarf patient had history of bronchial asthma with restriction of neck extension, managed successfully using combined spinal–epidural anesthesia.

    Full Text Available Introduction: Epinephrine-containing lidocaine is the most used anestheic drug in dentistry. The aim of this study was to investigate the hemodynamic changes following local infiltration of 2%lidocaine with 1:80,000 epinephrine in subjects undergoing orthognatic surgery under general anesthesia. Methods: Twenty five patients without any systemic disease participated. After general anesthesia, two cartridges of 2% lidocaine + 1:80,000 epinephrine were infiltrated around the surgery site. Systolic (SBP and diastolic (DBP blood pressure, mean arterial blood pressure (MAP, heart rate (HR, and blood sugar (BS were measured in three stages: before the injection (M1, at the end of injection (M2, and 10 min after injection (M3. Results: No significant difference observed in SBP, DBP, and MAP at the end of injection and 10 min later. HR was increased significantly after injection and remained significantly higher than baseline after 10 min. BS increased slightly at the end of injection and continued to increase after 10 min. However, changes in BS were not significant. Conclusion: Using two cartridges of epinephrine-containing lidocaine have slight systemic changes in healthy subjects; as a result, this dosage could be used in patients with cardiovascular complications undergoing general anesthesia.

    The thalamocortical network serves a role in both consciousness and sensorimotor processing. However, little is known regarding how changes in conscious states, via induction of and recovery from anesthesia, affect the processing of sensorimotor information in the thalamocortical network. To address this, we investigated the dynamics of causal interactions among sensorimotor rhythms (SMR; frequency range of 3-12Hz) across the thalamocortical network during transitions into and out of ketamine-induced unconsciousness. Two local field potentials from the ventral lateral and ventrobasal thalamic nuclei, as well as two intracranial electroencephalography signals from the primary sensory and primary motor regions, were recorded in 10 mice. Spectral Granger causality analysis revealed two distinct frequency-specific patterns in sensorimotor rhythms. For the low-frequency (3-6.5Hz) SMR, loss of consciousness evoked causal influences directed from the cortex to the thalamus. For the high-frequency (6.5-12Hz) SMR, causal influences from the primary sensory cortex to other regions during the conscious period were abruptly altered by loss of consciousness and gradually regenerated following recovery of consciousness. The results of the present study indicate that anesthesia alters the flow of sensorimotor information in the thalamocortical network and may provide evidence of the neural basis of loss and recovery of sensorimotor function associated with anesthesia.

    Full Text Available Background: The assessment of the anesthesia course in our university comprises Objective Structured Clinical Examinations (OSCEs, in conjunction with portfolio and multiple-choice questions (MCQ. The objective of this study was to evaluate the outcome of different forms of anesthesia course assessment among 5 th year medical students in our university, as well as study the influence of gender on student performance in anesthesia. Methods: We examined the performance of 154, 5 th year medical students through OSCE, portfolios, and MCQ. Results: The score ranges in the portfolio, OSCE, and MCQs were 16-24, 4.2-28.9, and 15.5-44.5, respectively. There was highly significant difference in scores in relation to gender in all assessments other than the written one (P=0.000 for Portfolio, OSCE, and Total exam, whereas P=0.164 for written exam. In the generated linear regression model, OSCE alone could predict 86.4% of the total mark if used alone. In addition, if the score of the written examination is added, OSCE will drop to 57.2% and the written exam will be 56.8% of the total mark. Conclusions: This study demonstrates that different clinical methods used to assess medical students during their anesthesia course were consistent and integrated. The performance of female was superior to male in OSCE and portfolio. This information is the basis for improving educational and assessment standards in anesthesiology and for introducing a platform for developing modern learning media in countries with dearth of anesthesia personnel.

    PurposeTo evaluate a modified superior hypogastric nerve block (SHNB) to reduce pain after uterine artery embolization (UAE) compared to epidural anesthesia.Materials and methodsIn this retrospective study, the amount of opiate drugs needed after UAE was compared between SHNB and epidural anesthesia. Eighty one consecutive women (mean age: 43.67 years) were in the SHNB group and 27 consecutive women (mean age: 43.48 years) treated earlier at the same institution in the epidural anesthesia group. UAE was performed from a unilateral femoral artery approach using a 4F catheter. 500–700 or 700–900 μm trisacryl gelatine microspheres were used as embolic agents. The SHNB was performed by advancing a 21G from the abdominal wall below the umbilicus to the anterior portion of the 5th vertebral body. For optimal guidance a cranio-caudal tilt of 5°–15° was used. On a lateral view the correct contrast distribution in front of the vertebral body is confirmed. Then 20 ml local anesthesia (ropivacain 0.75 %) is injected. In case of an asymmetric right–left distribution the needle was repositioned.ResultsAll SHNB were successful without severe complications. The mean time for the SHNB was 4 min 38 s (2 min 38 s–9 min 27 s). The needle was repositioned in average 0.87 times. The opiate dose for the SHNB group was 19.33 ± 22.17 mg which was significantly lower. The average time to receive an opiate drug after SHNB was 4 h 41 min.ConclusionThe SHNB is a safe and minimally time-consuming way to reduce pain after UAE especially within the first 4 h.

    Full Text Available Many studies have evaluated risk factors associated with complications after free flap surgery, but these studies did not evaluate the impact of anesthesia management. The goal of the current study was to evaluate the differences between patients who received inhalation and total intravenous anesthesia (TIVA in free flap surgery.One hundred and fifty-six patients who underwent free flap surgery for head and neck cancer were retrospectively divided into the TIVA (96 patients and the inhalation group (87 patients. Perioperative hemodynamic data and postoperative medical complications were determined by documented medical records.Ninety-six patients in the TIVA group were compared with 87 patients who received inhalation anesthesia. There were no differences in gender, age, classification of physical status based on American Society for Anesthesiologists (ASA score, and cormobidities between the two groups. Patients in the TIVA group required less perioperative crystalloid (4172.46 ± 1534.95 vs. 5183.91 ± 1416.40 ml, p < 0.0001 and colloid (572.46 ± 335.14 vs. 994.25 ± 434.65 ml, p < 0.0001 to maintain hemodynamic stability. Although the mean anesthesia duration was shorter in the TIVA group (11.02 ± 2.84 vs. 11.70± 1.96 hours, p = 0.017, the blood loss was similar between groups (p = 0.71. There was no difference in surgical complication rate, but patients in the TIVA group developed fewer pulmonary complications (18 vs. 47, p = 0.0008. After multivariate regression, patients in the TIVA group had a significantly reduced risk of pulmonary complication compared with the inhalation group (Odds ratio 0.41, 95% CI 0.18-0.92.Total intravenous anesthesia was associated with significantly fewer pulmonary complications in patients who received free flap reconstruction.

    The success of acupuncture anesthesia (AA) for pneumonectomy in Shanghai in 1960 was a key event for AA gaining practical clinical application. The effort was a close colaboration between the Shanghai First Tuberculosis Hospital and the Shangha i Institute of Acupuncture and Moxibustion. One of the most important factors of AA success was the great fi nancial and political support provided by the C hinese central government and S hanghai local government. In December1965 the S tate Science and Technology Commission of China issued a formal document acknowledging AA as an important fi rst-level n ational achievement of the integration of Chinese and Western medicine, and a colaborative effort of the whole scientifi c community in China. AA was an important infl uential factor that helped acupuncture spread across the world.

    Full Text Available Blood biochemical factors are changed by anesthesia in birds. Cortisol is one of these factors which related to inflammation and pain at surgery or post-operation. In present study, we evaluated effect of halothaneinduced anesthesia on plasma level of cortisol in pigeon. Ten domestic pigeons were used. The weight of birds was about 300 g. After 3 to 4 h food restriction, anesthesia was induced by halothane for celiotomy within 20 min. Anesthesia was induced by halothane at 2.5% with oxygen gas and it continued by 1.5% halothane. Blood sample was collected before, during and after surgery from pigeons and plasma level of cortisol was measured by commercial kit. Anesthesia induction and maintenance with halothane provided suitable anesthesia during celiotomy in pigeon. Plasma level of cortisol was significantly decreased after anesthesia. The mean of cortisol was 2.02 ng/mL before anesthesia and reached to 1.75 and 1.59 ng/mL in during and after anesthesia respectively. This change significantly differed with comparison to before surgery. But the mean of cortisol was not different significantly between duration of surgery and post operation. Halothane can decrease level of cortisol during anesthesia and so it decreases anti-inflammatory and analgesic effect of cortisol and also side effect of corticostroids.

    Full Text Available OBJECTIVE: We aim to compare selective spinal anesthesia and general anesthesia with regard to postoperative recovery and fast-track eligibility in day surgeries. MATERIALS AND METHOD: Sixty geriatric outpatient cases, with ASA II-III physical status and requiring shortduration transurethral intervention, were enrolled in the study. The cases were split into 2 groups: as general anesthesia (Group GA and selective spinal anesthesia (Group SSA. Group GA (n = 30 received propofol 2 mg kg-1 (until loss of eyelash reflex, remifentanil induction 0.5-1 µg kg-1, and laryngeal mask. Maintenance was achieved by 4-6% desflurane in 60% N2O and 40% O2 along with remifentanil infusion at 0.05 µg /kg-1 /min-1. Drugs were discontinued after the withdrawal of the ureteroscope, and extubation was carried out with 100% O2. Group SSA (n = 30 received 0.5% spinal anesthesia via L4-5 space by 0.5% hyperbaric bupivacaine 5 mg. Anesthesia preparation time, time to surgical anesthesia level, postoperative fast-tracking, and time to White-Song recovery score of 12, were noted. In the operating room, we evaluated hemodynamics, nausea/vomiting, surgeon and patient satisfaction with anesthesia, perioperative midazolam-fentanyl administration, postoperative pain, and discharge time. RESULTS: Anesthesia preparation time, length of surgery, anesthesia-related time in the operating room, time to sit, and time to walk were significantly low in Group GA (p < 0.05, whereas time to fast-track eligibility, length of stay in the PACU, discharge time, and other parameters were similar in both of the groups. CONCLUSION: While anesthesia preparation time, length of surgery, start time of surgery, time to sit, and time to walk were shorter in the General Anesthesia group, time to fast-track eligibility, phase 1 recovery time, and discharge time were similar among patients subjected to selective spinal anesthesia.

    Full Text Available Pregnancy induced hypertension is a hypertensive disorder, which occurs in 5% to 7% of all pregnancies. These parturients present to the labour and delivery unit ranging from gestational hypertension to HELLP syndrome. It is essential to understand the various clinical conditions that may mimic preeclampsia and the urgency of cesarean delivery, which may improve perinatal outcome. The administration of general anesthesia (GA increases morbidity and mortality in both mother and baby. The provision of regional anesthesia when possible maintains uteroplacental blood flow, avoids the complications with GA, improves maternal and neonatal outcome. The use of ultrasound may increase the success rate. This review emphasizes on the regional anesthetic considerations when such parturients present to the labor and delivery unit.

    Throughout its history, anesthesia and critical care medicine has experienced vast improvements to increase patient safety. Consequently, anesthesia has never been performed on such a high level as it is being performed today. As a result, we do not always fully perceive the risks involved in our daily activity. A survey performed in Swiss hospitals identified a total of 169 hot spots which endanger patient safety. It turned out that there is a complex variety of possible errors that can only be tackled through consistent implementation of a safety culture. The key elements to reduce complications are continuing staff education, algorithms and standard operating procedures (SOP), working according to the principles of crisis resource management (CRM) and last but not least the continuous work-up of mistakes identified by critical incident reporting systems.

    Full Text Available Labetalol, a combined alfa and beta-adrenergic receptor antagonist, is used as an antihypertensive drug. We report a case of an acute rise in blood pressure and lower limb pain due to the inadvertent intrathecal administration of labetalol, mistaking it for bupivacaine, during obstetric anesthesia. The situation was rescued by converting to general anesthesia. The cesarean delivery was uneventful, and mother as well as newborn child showed no ill-effect. This particular medication error was attributable to a failure on the part of the doctors administering the injection to read and cross-check medication labels and the practice of keeping multiple injections together. In the absence of an organized medication error reporting system and action on that basis, such events may recur in future.

    Patient safety has become an important aspect of national health care initiatives. The purpose of this evaluation was to measure the impact of a patient safety education series for students enrolled in a nurse anesthesia program. Baseline surveys that measured patient safety competencies across three domains, attitudes, skills and knowledge, were administered to the students. A patient safety education series was delivered to the cohort and the survey was then readministered. Mean scores were compared using independent samples t tests. Attitude scores did not change from baseline to posttest. Participants scored higher on posttest means for both the patient safety skills and knowledge domains. Incorporating patient safety content into the nurse anesthesia master's degree curriculum may enhance clinicians' skills and knowledge related to patient safety, and the addition of a patient safety curriculum is important during the formative education process.

    2015-09-01

    Transfemoral transcatheter aortic valve implantation (TAVI) is nowadays a routine therapy for elderly patients with severe aortic stenosis (AS) and high perioperative risk. With growing experience, further development of the devices, and the expansion to "intermediate-risk" patients, there is increasing interest in performing this procedure under conscious sedation (TAVI-S) rather than the previously favoured approach of general anesthesia (TAVI-GA). The proposed benefits of TAVI-S include; reduced procedure time, shorter intensive care unit (ICU) length of stay, reduced need for intraprocedural vasopressor support, and the potential to perform the procedure without the direct presence of an anesthetist for cost-saving reasons. To date, no randomized trial data exists. We reviewed 13 non-randomized studies/registries reporting data from 6,718 patients undergoing TAVI (3,227 performed under sedation). Patient selection, study methods, and endpoints have differed considerably between published studies. Reported rates of in-hospital and longer-term mortality are similar for both groups. Up to 17% of patients undergoing TAVI-S require conversion to general anesthesia during the procedure, primarily due to vascular complications, and urgent intubation is frequently associated with hemodynamic instability. Procedure related factors, including hypotension, may compound preexisting age-specific renal impairment and enhance the risk of acute kidney injury. Hypotonia of the hypopharyngeal muscles in elderly patients, intraprocedural hypercarbia, and certain anesthetic drugs, may increase the aspiration risk in sedated patients. General anesthesia and conscious sedation have both been used successfully to treat patients with severe AS undergoing TAVI with similar reported short and long-term mortality outcomes. The authors believe that the significant incidence of complications and unplanned conversion to general anesthesia during TAVI-S mandates the start-to-finish presence

MATERIAL AND METHODS: Pain scores of 16 patients were evaluated with a 5-point verbal rating scale (VRS and data were analyzed nonparametrically. Pain differences at needle insertion, during delivery of local anesthetic, and at tooth preparation, for conventional versus the Wand technique, were analyzed using the Mann-Whitney U test (p=0.01. RESULTS: The Wand technique had a lower pain level compared to conventional injection for needle insertion (p0.05. CONCLUSIONS: The AMSA technique using the Wand is recommended for prosthodontic treatment because it reduces pain during needle insertion and during delivery of local anaesthetic. However, these two techniques have the same pain levels for tooth preparation.

    Full Text Available Gas flows less than 1 L/min are defined as low-flow anesthesia. Although most of modern anaesthesia machines are equipped with circle re-breathing systems that can allow to use low fresh-gas flows, relatively high-flow techniques traditionally remain as the primary anaesthetic method. Several factors such as traditional anesthetic habits, insufficient training in the use of these techniques during the residency, and concerns on providing a desirable anesthetic depth limited its widespread use. However, it has many benefits, including decrease in use of inhalational anaesthetics, improvement of body temperature and humidity homeostasis, reduce in environmental pollution, and significant economical advantages. Low-flow anesthesia also carries some concerns such as increased hypoxia risk, potential for gas volume deficiency, misdosage of volatile agents, exhaustion of the absorbent, and accumulation of unwanted gases. Although this technique has some disadvantages, it has become a safe anaesthetic method with using modern anesthesia machines and new-generation anesthetic agents. The aim of this brief report is to describe the low-flow techniques, to indicate the benefits and potential risks, and to attract the attention of anesthesiologists on this important issue.

    Full Text Available Introduction : Hospital infections are one of the important reasons of mortality and incurred expenses. Therefore, we must control these infections by identifying contamination sources. The aim of this study was the determination of bacterial pollution of corrugated anesthesia sets in surgical rooms. Methods: This study was an analytic-description one performed in training hospitals of Yazd city. Research sample was 440 cases provided from different parts of corrugate after completing the anesthesia period by wet sterile swabs and transferred to culture media. On Thursday, each week, a sample from different parts of tube after sterilizing with cetrimide solution was obtained. Finally, after 24 hours, culture medias were studied for colony growth. Results: Obtained results indicated that of 440 cases taken samples, 343 cases were without bacterial pollution, 71 cases (19.29% had bacterial pollution of samples before sterilizing and 26 cases (36.1% were polluted after tube sterilizing. Conclusion: Sampling and culturing from used equipment and tools in hospital is one of the important actions for identifying and controlling hospital infections. Obtained results from this study indicated that of 440 cases, there were 97 cases of pollution. Therefore, it is suggested that anti bacterial filters should be installed before Y form piece of tubes in anesthesia machines and disposable corrugated tubes should replace traditional tubes. In addition, it seems necessary that wider investigations should be done.

    Full Text Available Biosignal analysis is one of the most important topics that researchers have tried to develop during the last century to understand numerous human diseases. Electroencephalograms (EEGs are one of the techniques which provides an electrical representation of biosignals that reflect changes in the activity of the human brain. Monitoring the levels of anesthesia is a very important subject, which has been proposed to avoid both patient awareness caused by inadequate dosage of anesthetic drugs and excessive use of anesthesia during surgery. This article reviews the bases of these techniques and their development within the last decades and provides a synopsis of the relevant methodologies and algorithms that are used to analyze EEG signals. In addition, it aims to present some of the physiological background of the EEG signal, developments in EEG signal processing, and the effective methods used to remove various types of noise. This review will hopefully increase efforts to develop methods that use EEG signals for determining and classifying the depth of anesthesia with a high data rate to produce a flexible and reliable detection device.

    Full Text Available Surgical removal of solid tumors is of utmost importance as total resection can be curative. The surgical insult however itself may result in tumor micrometastasis coupled with depression of cell-mediated immunity culminating in tumor recurrence. Recent research suggests that few anesthetic agents or procedures can influence pathophysiology of metastasis in the postoperative period. Whereas opioids and volatile anesthetics have been implicated in angiogenesis and immunosuppression, evidences accumulated over the recent years have undoubtedly highlighted the attenuation of immunosuppression by regional anesthetic agents thereby making it superior over general anesthesia in preventing cancer recurrence. As anesthetic drugs are given at that time when patient is at the maximum risk of spread of metastasis, thus an understanding of the effect of anesthesia drugs and their impact on tumor metastasis is important so that appropriate anesthetic strategy can be made to improve long term survival in these patients. The purpose of the present review is therefore to emphasize the pivotal role of various anesthetic agents and anesthesia techniques in preventing tumor recurrence after surgery.

    The gateways to advancements in medical fields have always been accessed through the coalition between various specialties. It is almost impossible for any specialty to make rapid strides of its own. However, the understanding of deeper perspectives of each specialty or super specialty is essential to take initiatives for the progress of the other specialty. Endocrinology and anesthesiology are two such examples which have made rapid progress in the last three decades. Somehow the interaction and relationship among these medical streams have been only scarcely studied. Diabetes and thyroid pathophysiologies have been the most researched endocrine disorders so far in anesthesia practice but even their management strategies have undergone significant metamorphosis over the last three decades. As such, anesthesia practice has been influenced vastly by these advancements in endocrinology. However, a comprehensive understanding of the relationship between these two partially related specialties is considered to be an essential cornerstone for further progress in anesthesia and surgical sciences. The current review is an attempt to imbibe the current and the changing perspectives so as to make the understanding of the relationship between these two medical streams a little simple and clearer.

    Full Text Available The potential uses of dexmedetomidine (DEX, a highly selective α2- adrenoceptor agonist are very diverse Although not orally active, DEX shows good bioavailability when administered via various other routes like intranasal, buccal, IM than intra-venous. DEX has similar pharmacokinetics in all age groups. Its side effects are predictable and easily treatable; hence it has found a place as a part of fast-tracking anesthesia regimens in children. DEX is the sedative of choice for peri-operative use in high- risk patients, since it is cardioprotective, neuroprotective and renoprotective. Premedication with DEX obtunds the autonomic pressor responses due to laryngoscopy and endotracheal intubation when used as an adjuvant to general anesthesia. DEX in high doses offers another approach to manage morbidly obese patients and patients with a compromised airway; without causing any cardiorespiratory depression. It is near ideal hypotensive agent used for controlled hypotension. Availability of an antidote (Atipamezole with similar elimination half-life is taking the drug into new frontiers .The aim of this review is to present the most recent topics regarding the advantages in using dexmedetomidine in clinical anesthesia and in critical care, while discussing the controversial issues of its harmful effects.

    Full Text Available Background: Regional anesthesia has an anti-inflammatory effect that blockade the C-fiber hence reduced cytokine production and blocked the activity of the sympathetic nerve fibers. Postoperative pain caused primarily by tissue inflammation and activity of the C-fibers in the manner of reduced the production of cytokines, regional anesthesia may limit the inflammatory response after surgery and severity of postoperative pain. Methods: This study is a clinical experimental study with randomized pre and post test control group design. A total of 24 samples were recruited in this study divided into two groups each consisting of 12 samples. The first group was given regional anesthesia method of continuous brachial plexus block with ultrasound guidance and the second group with general anesthesia method. T-test or Mann-Whitney continued multivariate linear regression analysis was performed to analyze the differences in treatment and not because of differences in the initial values with significance level of p<0.05. Results: This study reports that the mean decreased levels of IL-6 postoperatively in 1stgroup is 29.8 lower than in 2ndgroup and it is statistically significant p< 0.05. There was an increase of IL-10 mean levels from preoperative to postoperatively with significance level of p<0.05 in both groups. Declined in the mean levels of PAF postoperatively in 1st group 1.3 lower than 2nd group and it was statistically significant p<0.05. The declined of  postoperative VAS in 1st group is 3.1 lower than 2nd group and it is statistically significant p< 0.05, and it also contained the pure effect of PAF levels against value of VAS that any increased 1ng/ml levels of PAF then an increase in the value of 0.18 cm VAS and this was statistically significant p<0.05.

    Twenty-eight patients undergoing upper abdominal operations (mainly selective proximal vagotomy [SPV]) were referred for assessment of the hormonal metabolic reaction (adrenocorticotropic hormone [ACTH], arginine vasopressin [AVP], cortisol, and glucose), the postoperative pain reaction, and respiration according to the method of anesthesia (group 1: neuroleptanesthesia [NLA], group 2: NLA in combination with epidural opiate analgesia, group 3: NLA in combination with local anesthesia). To alleviate postoperative pain piritramide was systematically administered in group 1, whereas in groups 2 and 3 a thoracic epidural catheter was injected with morphine or bupivacaine. Postoperative analgesia was better in patients with epidural administration than in those with systemic application. On the 1st and 2nd postoperative days the vital capacity was statistically significantly higher by 10%-15% in groups 2 and 3 than in group 1. As expected, the neurohormonal and metabolic stress response was highest in all patients in the intraoperative and immediate postoperative phases: ACTH, AVP, and glucose levels were in most cases significantly higher compared with the initial values. However, cortisol levels decreased intraoperatively, probably as a result of the generally used induction agent etomidate. Comparison of the three methods of anesthesia revealed that all mean hormone levels analyzed in group 2 patients were lower both intraoperatively and 2 h postoperatively, which implies that epidurally administered morphine reduces the stress reaction, probably indirectly through additional selective alleviation of pain at the spinal cord level. The various differences in hormonal reactions of patients in groups 1 and 3 gave no clear evidence, however, of possible mitigation of the stress reaction by epidural local anesthetics in upper abdominal operations.

    Anesthesia for a patient with pheochromocytoma is challenging; irrespective of whether it is a diagnosed case for planned surgery or an occult case, it can be a nightmare. The patient may be given anesthesia for removal of the primary tumor or for surgery other than for the removal of the primary tumor. Hemodynamic derangements like hypertension and arrhythmia can be catastrophic. Monitored anesthesia care, though used for many cases, is unusual for a patient with diagnosed pheochromocytoma, ...

    Deep anesthesia is commonly used as a model of slow-wave sleep (SWS). Ketamine-xylazine anesthesia reproduces the main features of sleep slow oscillation: slow, large amplitude waves in field potential, which are generated by the alternation of hyperpolarized and depolarized states of cortical neurons. However, direct quantitative comparison of field potential and membrane potential fluctuations during natural sleep and anesthesia is lacking, so it remains unclear how well the properties of s...

    Clinical monitoring is an essential part of the profession of anesthesiology. It would therefore be impossible to review all articles published in the Journal of Clinical Monitoring and Computing that are relevant to anesthesia. Because other reviews will address monitoring of the respiratory and cardiovascular system, the current review will limit itself to topics uniquely related to anesthesia. The topics are organized according to the chronological order in which an anesthetic proceeds: secure the airway; ventilate and deliver anesthetic gases; monitor vital organ function and anesthetic depth; and ensure analgesia during/after emergence from anesthesia (locoregional anesthesia and pain control).

    Abstract Inhalation anesthetics provide myocardial protection for cardiac surgery. This study was undertaken to compare the perioperative effects between isoflurane and fentanyl-midazolam-based anesthesia for heart transplantation. A retrospective cohort study was conducted by reviewing the medical records of heart transplantation in a single medical center from 1990 to 2013. Patients receiving isoflurane or fentanyl-midazolam-based anesthesia were included. Those with preoperative severe pulmonary, hepatic, or renal comorbidities were excluded. The perioperative variables and postoperative short-term outcomes were analyzed, including blood glucose levels, urine output, inotropic use, time to extubation, and length of stay in the intensive care units. After reviewing 112 heart transplantations, 18 recipients with fentanyl-midazolam-based anesthesia, and 29 receiving isoflurane anesthesia with minimal low-flow technique were analyzed. After cessation of cardiopulmonary bypass, recipients with isoflurane anesthesia had a significantly lower mean level and a less increase of blood glucose, as compared with those receiving fentanyl-based anesthesia. In addition, there was less use of dobutamine upon arriving the intensive care unit and a shorter time to extubation after isoflurane anesthesia. Compared with fentanyl-midazolam-based anesthesia, isoflurane minimal low-flow anesthesia maintained better perioperative homeostasis of blood glucose levels, less postoperative use of inotropics, and early extubation time among heart-transplant recipients without severe comorbidities.

    In this review article, we address issues related to using data from anesthesia information management systems (AIMS) to deliver near real-time alerts via AIMS workstation popups and/or alphanumeric pagers and post hoc reports via e-mail. We focus on reports and alerts for influencing the behavior of anesthesia providers (i.e., anesthesiologists, anesthesia residents, and nurse anesthetists). Multiple studies have shown that anesthesia clinical decision support (CDS) improves adherence to protocols and increases financial performance through facilitation of billing, regulatory, and compliance documentation; however, improved clinical outcomes have not been demonstrated. We inform developers and users of feedback systems about the multitude of concerns to consider during development and implementation of CDS to increase its effectiveness and to mitigate its potentially disruptive aspects. We discuss the timing and modalities used to deliver messages, implications of outlier-only versus individualized feedback, the need to consider possible unintended consequences of such feedback, regulations, sustainability, and portability among systems. We discuss statistical issues related to the appropriate evaluation of CDS efficacy. We provide a systematic review of the published literature (indexed in PubMed) of anesthesia CDS and offer 2 case studies of CDS interventions using AIMS data from our own institution illustrating the salient points. Because of the considerable expense and complexity of maintaining near real-time CDS systems, as compared with providing individual reports via e-mail after the fact, we suggest that if the same goal can be accomplished via delayed reporting versus immediate feedback, the former approach is preferable. Nevertheless, some processes require near real-time alerts to produce the desired improvement. Post hoc e-mail reporting from enterprise-wide electronic health record systems is straightforward and can be accomplished using system

We discuss the timing and modalities used to deliver messages, implications of outlier-only versus individualized feedback, the need to consider possible unintended consequences of such feedback, regulations, sustainability, and portability among systems. We discuss statistical issues related to the appropriate evaluation of CDS efficacy. We provide a systematic review of the published literature (indexed in PubMed) of anesthesia CDS and offer 2 case studies of CDS interventions using AIMS data from our own institution illustrating the salient points. Because of the considerable expense and complexity of maintaining near real-time CDS systems, as compared with providing individual reports via e-mail after the fact, we suggest that if the same goal can be accomplished via delayed reporting versus immediate feedback, the former approach is preferable. Nevertheless, some processes require near real-time alerts to produce the desired improvement. Post hoc e-mail reporting from enterprise-wide electronic health record systems is straightforward and can be accomplished using system

    Full Text Available Background: Various adjuncts have been used with lignocaine to decrease tourniquet pain and prolong post-operative analgesia during intravenous regional anesthesia (IVRA. Calcium-channel blockers potentiate the analgesic effect of local anesthetics. This study was designed to evaluate the efficacy of diltiazem as an adjunct to lignocaine in IVRA with respect to tourniquet tolerance, perioperative analgesia, and quality of anesthesia. Methods: In this prospective, randomized, and double-blind study, 40 patients (American Society for Anesthesiologists grade I/II undergoing elective hand surgery under IVRA were assigned into two groups of 20 each and administered IVRA either with lignocaine 3 mg/kg (group Lignocaine (L or lignocaine 3 mg/kg plus diltiazem 0.2 mg/kg (group Lignocaine-Diltiazem (LD with normal saline (total volume-40 ml. Hemodynamic parameters, onset of the complete sensory blockade, motor blockade, and intraoperative (tourniquet pain and post-operative Visual Analogue Scale scores, total intraoperative and consumption of post-operative fentanyl intraoperative were recorded. Results: Sensory block was established in 2.5±0.688 min in group LD verses 5.60±0.851 min in group L. Motor blockade was established in 8.65±0.933 min in group LD and 13.46±0.604 min in group L. The mean VAS scores >3 were attained early at 30 min (3.1±0.912 in group L. Patients in group L requested early rescue analgesic at 30±8.633 min compared with 49.64±7.958 min in group LD. Conclusions: Diltiazem as an adjunct to lignocaine provided enhanced intraoperative and post-operative analgesia without any significant side effects.

    Full Text Available Clinical hematology facilitates the diagnosis of disease and can act as a prognostic indicator of pathological conditions in fish. The aim of the present study was to evaluate hematological parameters of Nile tilapia (Oreochromis niloticus subjected to different anesthetics and anticoagulants. Thirty apparently healthy fishes (average weight of 473 ± 35. 50 g and mean total length of 29. 33 ± 0. 37 cm, were selected from the local commercial fish farm in the Lages municipality (Santa Catarina, Brazil. The animals were randomly divided into three groups of 10. In two groups, anesthesia was induced with eugenol (70 mg·L- 1 (EG and Benzocaine hydrochloride (100 mg·L-1 (BG, respectively. Anesthesia was not administered to fish of the third group (CG/control group. Blood samples were obtained by venipuncture of the caudal vessels and placed into microtubes containing sodium heparin or Na2EDTA for further analysis. The results were analyzed by Sigma Stat for Windows, the paired t-test for significant differences between anticoagulants of the same group, and analysis of variance followed by the Tukey test for comparison of means between groups (p ? 0. 05. Most of the observed changes in the erythrogram were significantly higher for the anticoagulant heparin and benzocaine group in comparison to the control group. However, the values obtained for the leukogram were significantly higher for all groups subjected to the Na2EDTA anticoagulant, suggesting that heparin may cause cell clumping. The results suggest that the anesthetics under investigation effectively minimizes the effects of stress caused by handling and invasive procedures, and that the anticoagulant heparin causes less hemolysis in comparison to Na2EDTA for Nile tilapia. Thus, the hematological variations attributed to different anesthetic protocols and/or different anticoagulants should be considered for the species Oreochromis niloticus.

    Full Text Available Background/Aim. Bupivacaine (Marcaine®, homologue of mepivacaine, chemically related to lidocaine, is used as a local anesthetic for local infiltration, peripheral nerve block, retrobulbar block, symphathetic block, and caudal and epidural anesthesia. The aim of this investigation was to determine and to compare clinical parameters of the local anesthetic effects of bupivacaine applied with and without a vasoconstrictor. Methods. This investigation included a total of 30 randomly selected patients, who ranged in age from 30−60 years, with partial or total anodontia in the molar region of the mandible. These patients with total or partial edentulous molar part of the mandible, scheduled for dental implantation placement, were asked to participate in the study. In the first phase of the investigation, the patients were subjected to local anesthesia with 3.5 cm3 of 0.5% bupivacaine with a vasoconstrictor (adrenalin, 1: 200 000 in the right side of the mandible. After administering local anesthesia, the placement of blade, cylindrical, transdental (B.C.T. implants was performed. In the second stage of the investigation, in 7−10 days period after the first oral surgery, the patients were subjected to local anesthesia with 3.5 cm3 of 0.5% bupivacaine, but without a vasoconstrictor, in the left side of the mandible. After administering local anesthesia, the placement of B.C.T. implants was performed. During the performance of both oral surgery procedures, the following clinical parameters of the local anesthetic effects were monitored: latent period, duration and the potency of anesthesia, and the evaluation of the postoperative pain level. Results. The latent period under local anesthesia with 3.5 cm3 of 0.5% bupivacaine and vasoconstrictor was statistically significantly shorter than without vasoconstrictor. The duration of local anesthesia was longer without vasoconstrictor. There was no difference in the potency of anesthesia with or without a

    Background and Objectives The presence of sleep apnea (SA) among surgical patients has been associated with significantly increased risk of perioperative complications. Although regional anesthesia has been suggested as a means to reduce complication rates among SA patients undergoing surgery, no data are available to support this association. We studied the association of the type of anesthesia and perioperative outcomes in patients with SA undergoing joint arthroplasty. Methods Drawing on a large administrative database (Premier Inc), we analyzed data from approximately 400 hospitals in the United States. Patients with a diagnosis of SA who underwent primary hip or knee arthroplasty between 2006 and 2010 were identified. Perioperative outcomes were compared between patients receiving general, neuraxial, or combined neuraxial-general anesthesia. Results We identified 40,316 entries for unique patients with a diagnosis for SA undergoing primary hip or knee arthroplasty. Of those, 30,024 (74%) had anesthesia-type information available. Approximately 11% of cases were performed under neuraxial, 15% under combined neuraxial and general, and 74% under general anesthesia. Patients undergoing their procedure under neuraxial anesthesia had significantly lower rates of major complications than did patients who received combined neuraxial and general or general anesthesia (16.0%, 17.2%, and 18.1%, respectively; P = 0.0177). Adjusted risk of major complications for those undergoing surgery under neuraxial or combined neuraxial-general anesthesia compared with general anesthesia was also lower (odds ratio, 0.83 [95% confidence interval, 0.74–0.93; P = 0.001] vs odds ratio, 0.90 [95% confidence interval, 0.82–0.99; P = 0.03]). Conclusions Barring contraindications, neuraxial anesthesia may convey benefits in the perioperative outcome of SA patients undergoing joint arthroplasty. Further research is needed to enhance an understanding of the mechanisms by which neuraxial

    Deep anesthesia is commonly used as a model of slow-wave sleep (SWS). Ketamine-xylazine anesthesia reproduces the main features of sleep slow oscillation: slow, large-amplitude waves in field potential, which are generated by the alternation of hyperpolarized and depolarized states of cortical neurons. However, direct quantitative comparison of field potential and membrane potential fluctuations during natural sleep and anesthesia is lacking, so it remains unclear how well the properties of sleep slow oscillation are reproduced by the ketamine-xylazine anesthesia model. Here, we used field potential and intracellular recordings in different cortical areas in the cat to directly compare properties of slow oscillation during natural sleep and ketamine-xylazine anesthesia. During SWS cortical activity showed higher power in the slow/delta (0.1-4 Hz) and spindle (8-14 Hz) frequency range, whereas under anesthesia the power in the gamma band (30-100 Hz) was higher. During anesthesia, slow waves were more rhythmic and more synchronous across the cortex. Intracellular recordings revealed that silent states were longer and the amplitude of membrane potential around transition between active and silent states was bigger under anesthesia. Slow waves were mostly uniform across cortical areas under anesthesia, but in SWS, they were most pronounced in associative and visual areas but smaller and less regular in somatosensory and motor cortices. We conclude that, although the main features of the slow oscillation in sleep and anesthesia appear similar, multiple cellular and network features are differently expressed during natural SWS compared with ketamine-xylazine anesthesia.

    An increase in natural killer (NK) cell activity can be conditioned with a one trial learning paradigm to demonstrate the interaction between the central nervous system (CNS) and the immune system. In order to demonstrate learning possibilities during 'non-conscious' state, mice were anesthetized with a ketamin/rompun mixture and underwent one trial learning with odor cue as the conditioned stimulus (CS) preceding the unconditioned stimulus (US). The results indicated that mice that were exposed to camphor odor cue under the influence of anesthesia can associate the signal with the poly I:C unconditioned stimulus and were able to recall the conditioned response upon reexposure to the CS. Secondly, the conditioned association made in a conscious state can be recalled by exposure to the same olfactory odor cue in a 'non-conscious' state. The increase in the conditioned change in NK cell activity of both situations was significantly higher than the control group. The results demonstrate that learning can take place and the learned response can be recalled under the reduced awareness caused by anesthesia. The findings we report are unusual and novel in that they demonstrate that the CNS can learn new associations under conditions where the host is apparently unaware of the signals being linked. Anesthesia combined with the long interstimulus interval indicates that certain neuronal pathways in the CNS are receptive to second signals (elicited by the US) even when the second signal is separated by one day. This means the conditioned learning of a physiological response can take place unconsciously at a separate level and under situations where the host is totally unaware of the events which the brain is processing and linking as incoming information.

    Background: Bacterial contamination of anesthesia breathing machines and their potential hazard for pulmonary infection and cross-infection among anesthetized patients has been an infection control issue since the 1950s. Disposable equipment and bacterial filters have been introduced to minimize this risk. However, the machines’ internal breathing-circuit-system has been considered to be free of micro-organisms without providing adequate data supporting this view. The aim of the study was to investigate if any micro-organisms can be yielded from used internal machines’ breathing-circuit-system. Based on such results objective reprocessing intervals could be defined. Methods: The internal parts of 40 anesthesia machines’ breathing-circuit-system were investigated. Chi-square test and logistic regression analysis were performed. An on-site process observation of the re-processing sequence was conducted. Results: Bacterial growth was found in 17 of 40 machines (43%). No significant difference was ascertained between the contamination and the processing intervals. The most common contaminants retrieved were coagulase negative Staphylococci, aerobe spore forming bacteria and Micrococcus species. In one breathing-circuit-system, Escherichia coli, and in one further Staphylococcus aureus were yielded. Conclusion: Considering the availability of bacterial filters installed on the outlet of the breathing-circuit-systems, the type of bacteria retrieved and the on-site process observation, we conclude that the contamination found is best explained by a lack of adherence to hygienic measures during and after re-processing of the internal breathing-circuit-system. These results support an extension of the re-processing interval of the anesthesia apparatus longer than the manufacturer’s recommendation of one week. However, the importance of adherence to standard hygienic measures during re-processing needs to be emphasized. PMID:22242095

    Background Epinephrine infiltration of the nasal mucosa causes hypotension during functional endoscopic sinus surgery (FESS) under general anesthesia. A prospective randomized-controlled study was designed to determine whether relatively light general anesthesia is superior to fluid expansion in reducing epinephrine-induced hypotension during FESS.Methods Ninety patients undergoing elective FESS under general anesthesia were randomly assigned to three groups with 30 patients in each. Each patient received local infiltration with adrenaline-containing (5 μg/ml) lidocaine (1%,4 ml) under different conditions. For Group Ⅰ, anesthesia was maintained with propofol 2 μg/ml and rimifentanil 2 ng/ml by TCI. Group Ⅱ (control group) and Group Ⅲ received propofol 4 μg/ml and rimifentanil 4 ng/ml, respectively. In Groups Ⅰ and Ⅱ, fluid expansion was performed with hetastarch 5 mi/kg within 20 minutes; hetastarch 10 ml/kg was used in Group Ⅲ. Mean arterial pressure (MAP) and heart rate (HR) were recorded at 30-second-intervals for 5 minutes after the beginning of local infiltration. Simultaneously, the lowest and the highest MAP were recorded to calculate the mean maximum increase or decrease percent in MAP for all patients in each group. Data analysis was performed by χ2 test,one-way analysis of variance, or one-way analysis of covariance.Results Hemodynamic changes, particularly a decrease in MAP accompanied by an increase in HR at 1.5 minutes(P<0.05), were observed in all groups. The mean maximum decrease in MAP below baseline was 14% in Group Ⅰ, 24% in Group Ⅲ and 26% in Group Ⅱ. There were statistically significant differences between Group Ⅰ and Groups Ⅱ and Ⅲ(P<0.05). The mean maximum increase in MAP above baseline was 9% in Group Ⅰ, 6% in Group Ⅲ and 2% in Group Ⅱ.Conclusion Relatively light general anesthesia can reduce the severity of epinephrine-induced hypotension more effectively than fluid expansion during FESS under general

    The evidence on the attitude of 60 cancer out-patients to fibrocolonoscopy carried out under general anesthesia was evaluated versus different procedures of intravenous injection. Most patients were scared prior to examination; 83.3% felt sleepy during the procedure while 85% of those anesthetized wouldn't mind receiving narcosis for repeat examination. Propofol (diprivan) alone showed an advantage over midazolam (dormicum) in being more tolerable and cutting stay at hospital by a third. Ketamin proved undesirable due to psychomimetic effects and delayed regaining of consciousness.

    Balanced anesthetic techniques are commonly used in equine patients, and include the combination of a volatile anesthetic with at least one injectable anesthetic throughout the maintenance period. Injectable anesthetics used in balanced anesthesia include the α2-agonists, lidocaine, ketamine, and opioids, and those with muscle-relaxant properties such as benzodiazepines and guaifenesin. Administration of these injectable anesthetics is best using constant-rate infusions based on the pharmacokinetics of the drug, which allows steady-state concentrations and predictable pharmacodynamic actions. This review summarizes the different drug combinations used in horses, and provides calculated recommended doses based on the pharmacokinetics of individual drugs. PMID:23498047

    The physiological application of OHMS LAW explains the basis of hypotensive anesthesia. V = IR translates into: Pressure = Flow × Resistance or Blood pressure = Cardiac Output × Peripheral Resistance. If peripheral resistance is reduced by a vasodilator such as sodium nitroprusside (a short acting, vascular smooth muscle relaxant) or phenoxybenzamine (a long acting α adrenoreceptor antagonist), blood pressure will fall and vasoconstriction and bleeding will be reduced. A less desirable alternative to lowering blood pressure could be to reduce cardiac output by suppressing myocardial contractility using a ß(1) adrenoceptor antagonist or an inhalational agent such as isoflurane.

    Abstract Fentanyl-induced cough (FIC) is unwanted in the patients requiring stable induction of general anesthesia. This study was designed to evaluate the suppressive effects of butorphanol pretreatment on the incidence and severity of FIC during the induction of general anesthesia. A total of 315 patients of American Society of Anesthesiologists physical status I and II, scheduled for elective surgery under general anesthesia were randomized into 3 equally sized groups (n = 0105). Two minutes before fentanyl bolus, group I received intravenously 5 mL normal saline, groups II and III received butorphanol 0.015 and 0.03 mg/kg (diluted with saline to 5 mL), respectively. Patients were then administrated with fentanyl 2.5 μg/kg within 5 s. The incidence and severity of FIC was recorded for 2 minutes after fentanyl bolus. During experimental period, the mean arterial pressure, heart rate, and peripheral capillary oxygen saturation (SpO2) were recorded before the administration of butorphanol or normal saline (T0), 2 minutes (T1) after butorphanol injection, and 2 minutes (T2) after fentanyl injection. The incidence of FIC was 31.4% in group I, 11.4% in group II, and 3.8% in group III. Group III had a lowest incidence of FIC among 3 groups (P < 0.001, vs group I; P < 0.05, vs group II). The severe FIC was not observed in groups II and III, but was recoded from 6 patients in group I. At 2 minutes after fentanyl injection (T2), the mean arterial pressure was significantly higher in group I than that in groups II and III (P < 0.01, vs group II; P < 0.05, vs group III), but the values remained within safe limits. In conclusion, pretreatment with butorphanol could effectively and safely suppress FIC during anesthesia induction. PMID:27367987

    Full Text Available PHACE syndrome was first described by Dr. Ilonia Frieden and colleagues in 1996. It is an under-recognized rather than a very rare condition among patients with large facial hemangiomas. It is challenging as it has significant neurological, vascular and airway implications. Vascular malformations compromising cerebral blood flow predispose the patient to strokes and seizures. Subglottic hemangiomas, if present, could bleed during intubation. Meticulous neurological monitoring is mandatory in those undergoing repair of the great vessels. We describe the perioperative management of a child with PHACE syndrome subjected to dental treatment under general anesthesia.

    2016-07-01

    Full Text Available The exposure of neonates, infants and small children to general anesthesia is becoming a common occurrence. Accumulating preclinical data indicate that exposure to commonly used general anesthetic agents during key periods of brain development in this population(between late gestation and 3 to 4 years of age, can lead to apoptotic neurodegeneration, synapse loss, and cognitive and neurobehavioral deficits that persist as the organism matures. New work suggests that infants and small children undergoing some types of surgery could have better recovery if they receive regional anesthesia rather than general anesthesia. In response to this concerns, the Food and drug administration (FDA and the International Research Society in anesthesia (IARS started an initiative called Smart Tots (Strategies for Mitigating Anesthesia- related neuro Toxicity in Tots which examine the effects of anesthesia on brain development. Also another two major prospective studies are ongoing in children : PANDA (Pediatric Anesthesia Neurodevelopment assessment Study project is a large, multi-center study based at the Morgan Stanley Children’s Hospital of New York at Columbia University, and another one is GAS study which is a multisite randomized controlled trial comparing neurodevelopment outcomes in infant receiving general anesthesia compared to spinal and other regional anesthetics to the stress response to surgery. The findings from these studies will help researches to design the safest anesthetic regimens and to develop the new and safer anesthetic drugs for use in pediatric medicine.

    General anesthesia or monitored anesthesia care sometimes is provided in nonoperating room (OR) locations during nights and weekends (e.g., for magnetic resonance imaging [MRI] or computerized tomography [CT]). Rational and consistent scheduling and sequencing decisions for these diagnostic imaging procedures, including coordination with OR cases, cannot be done without knowing how long each case can wait to be started without risking a worsening of the patient's condition. We reviewed the medical records of the 81 patients who underwent diagnostic imaging procedures (78 = MRI, 3 = CT scan) under general anesthesia or monitored anesthesia care either on weekends or between 6 pm and 6 am at the University of Iowa Hospitals between March 2012 and February 2014. For 77.8% of patients, the indications could have changed clinical management within 4 hours (N = 63/81). Among the 63 imaging studies with potential immediate impact, there was documentation of results having been communicated to the treating team within 4 hours of the completion of imaging for 39 of the patients. Among the 39 patients, 15 promptly received medications or underwent procedures based on the imaging results. Thus, 15 of the 81 patients had a change in care (18.5%, 95% lower confidence limit = 11.2%). Our results are important since we showed previously that it is not possible to make rational and consistent decisions in case sequencing without knowing how long each case (including diagnostic imaging procedures) can wait to be started without a change in the patient's risk. The scheduled surgical procedure itself provides sufficient information to assess safe waiting times to start add-on cases (e.g., appendectomy). In contrast, MRI provides no context as to how potential findings will influence treatment. Our results show that the assumption cannot reasonably be made when sequencing cases that all imaging studies can or cannot wait longer than pending surgical procedures. Our results show that

METHODS: Male Sprague Dawley rats were randomized to anesthesia with isoflurane (n=11) or fentanyl...... samples for Endothelin-1 and cathecolamines were drawn before and after CA. KEY FINDINGS: Compared with fentanyl/fluanisone/midazolam anesthesia, isoflurane resulted in a shorter time to return of spontaneous circulation (ROSC), less use of epinephrine, increased coronary perfusion pressure during CPR......, higher mean arterial pressure post ROSC, increased plasma levels of Endothelin-1 and decreased levels of epinephrine. The choice of anesthesia did not affect ROSC rate or systemic O2 consumption. CONCLUSION: Isoflurane reduces time to ROSC, increases coronary perfusion pressure, and improves hemodynamic...

  11. Dopamine uptake dynamics are preserved under isoflurane anesthesia.

    2015-10-01

    Fast scan cyclic voltammetry is commonly used for measuring the kinetics of dopamine release and uptake. For experiments using an anesthetized preparation, urethane is preferentially used because it does not alter dopamine uptake kinetics compared to freely moving animals. Unfortunately, urethane is highly toxic, can induce premature death during experiments, and cannot be used for recovery surgeries. Isoflurane is an alternative anesthetic that is less toxic than urethane, produces a stable level of anesthesia over extended periods, and is often used for recovery surgeries. Despite these benefits, the effects of isoflurane on dopamine release and uptake have not been directly characterized. In the present studies, we assessed the utility of isoflurane for voltammetry experiments by testing dopamine signaling parameters under baseline conditions, after treatment with the dopamine uptake inhibitor cocaine, and after exposure to increasing concentrations of isoflurane. Our results indicate that surgical levels of isoflurane do not significantly alter terminal mechanisms of dopamine release and uptake over prolonged periods of time. Consequently, we propose that isoflurane is an acceptable anesthetic for voltammetry experiments, which in turn permits the design of studies in which dopamine signaling is examined under anesthesia prior to recovery and subsequent experimentation in the same animals.

    Thyroidectomy is the most common endocrine surgical procedure being carried out throughout the world. Besides, many patients who have deranged thyroid physiology, namely hyperthyroidism and hypothyroidism, have to undergo various elective and emergency surgical procedures at some stage of their life. The attending anesthesiologist has to face numerous daunting tasks while administering anesthesia to such patients. The challenging scenarios can be encountered at any stage, be it preoperative, intra-op or postoperative period. Preoperatively, deranged thyroid physiology warrants optimal preparation, while anticipated difficult airway due to enlarged thyroid gland further adds to the anesthetic challenges. Cardiac complications are equally challenging as also the presence of various co-morbidities which make the task of anesthesiologist extremely difficult. Thyroid storm can occur during intra-op and post-op period in inadequately prepared surgical patients. Postoperatively, numerous complications can develop that include hemorrhage, laryngeal edema, nerve palsies, tracheomalacia, hypocalcemic tetany, pneumothorax, etc., The present review aims at an in-depth analysis of potential risk factors and challenges during administration of anesthesia and possible complications in patients with thyroid disease.

    2011-01-01

    Tricaine methanesulfonate (TMS) is the only FDA approved anesthetic for use in a select number of fish species, including salmonids. It is used widely in hatcheries and research to immobilize fish for marking or transport and to suppress sensory systems during invasive procedures. Improper use can decrease fish viability and possibly distort physiological data. Since animals may be anesthetized by junior staff or students who may have little experience in fish anesthesia, training in the proper use of TMS may decrease variability in results and increase fish survival. This document acts as a primer on the use of TMS for anesthetizing juvenile salmonids, with an emphasis on its use in surgical applications. Within, we briefly discuss many aspects TMS. We describe the legal uses for TMS, and what is currently known about the proper storage and preparation of the anesthetic. We outline methods and precautions for administration and changes in fish behavior during progressively deeper anesthesia. We also discuss the physiological effects of TMS and its potential for decreasing fish health.

    Arthrofibrosis is a known complication of hallux valgus surgery. Joint manipulation under anesthesia has been studied for adhesive capsulitis of the shoulder; however, a paucity of published data exists on the use of this modality in the foot and ankle. The purpose of the present study was to investigate the outcomes of first metatarsophalangeal joint manipulation for arthrofibrosis that occurred as a complication of bunion surgery. The study population consisted of patients attending a single foot and ankle specialty clinic who were evaluated for arthrofibrosis after bunion surgery. Patients who underwent joint manipulation under anesthesia were asked to complete a research visit in which a clinical examination was performed and the presence and severity of joint pain were assessed. A total of 38 patients (34 females, 4 males, 53 feet), with a mean age of 55.7 ± 11.8 (range 30 to 83) years, agreed to participate. The mean follow-up period was 6.5 ± 3.4 (range 1 to 17) years. The visual analog scale scores improved significantly from baseline to the final follow-up visit (baseline 6.5 ± 1.5, range 2 to 10; final follow-up visit 2.3 ± 1.5, range 0 to 6; p mobility and alleviating pain in patients who experience arthrofibrosis after surgical correction of hallux valgus.

    Full Text Available Niemann-Pick disease (NPD is an autosomal recessive, lipid storage disorder caused by the deficiency of the lysosomal enzyme sphingomyelinase or defective cholesterol transport from lysosome to cytosol. The clinical symptoms and signs include dysphagia, loss of motor function, hepatosplenomegaly, recurred respiratory infections, seizure, mental retardation, spasticity, myoclonic jerks and ataxia, but vary depending on the type of this disease. According to the observed pathology, patients require specialized therapy. Due to the high prevalence of the pathology in this group of patients, surgical interventions requiring general anaesthesia are common. Anesthetists have some difficulties with this group of patients. One of them is difficult ventilation because of hepatosplenomegaly and the other is difficult intubation. The metabolism of some of the anesthetic agents may be affected due to chronic use of anticonvulsant agents. Liver enzymes are elevated and platelet counts are reduced. Here we report an anesthesia management, difficulties and post-op follow up in a female child having NPD. Anesthetists have some difficulties in ventilation and intubation with NPD patients. In this situation ventilation should be with low tidal volume and high frequency. Because anesthetic agents might cause liver damage, they should be used cautiously. As a result, with keeping mind all these pathologies, anesthesia management to these patients should be used cautiously. (Journal of Current Pediatrics 2013; 11: 42-4

    Changes of circulating blood volume (CB volume) measured by the dual indicator dilution method were observed in 33 chronically instrumented mongrel dogs following either alpha-chloralose-urethane (C group), additive isoflurane (I group) or sevoflurane anesthesia (S group). These anesthetic groups were each divided into two subgroups with regard to respiratory care, namely Cp, Ip and Sp for those with intermittent positive pressure ventilation (six animals per subgroups), and Cs, Is and Ss for those with spontaneous breathing (five animals per subgroups). The CB volume under positive pressure ventilation remained unchanged in the Ip and Sp groups at both 0.5 and 1.0 MAC, and in the Cp group. The CB volume remained essentially unchanged in the Cs and Is groups at both 0.5 or 1.0 MAC, but the plasma volume tended to increase slightly in the Is group at 1.0 MAC. In the Ss group under spontaneous breathing, however, the CB volume increased from 84.4 +/- 7.0 to 91.4 +/- 7.7 at 0.5 MAC, and to 91.4 +/- 10.2 ml.kg(-1) at 1.0 MAC (0.01 < P < 0.05). These increases were caused by an increase in the plasma volume. The above data suggests that a concomitant increase in the venous pressure associated with an increase in the intrathoracic pressure produced by positive pressure ventilation would attenuate changes in the CB volume during sevoflurane anesthesia.

    Full Text Available Electroconvulsive therapy (ECT is a form of treatment which is very effective in many psychiatric disorders. The administration of anesthesia plays a positive role in the success of ECT and improves the oxygenation of the body during the process. Succinylcholine, is a depolarizing neuromuscular blocker of choice, the most common agent used to provide muscular relaxation during ECT. Alternative neuromusculer blokers have been used during anesthesia because of contraindications and serious side effects of succinylcholine. Rocuronium is a nondepolarizing neuromuscular blocker with inter-mediate time of action which may be used safely during ECT. Although relatively late onset of action and long half life compared to succinylcholine may seem as drawbacks, the new generation reversing agents like suggamadex have made these disadvantages ignorable. Sugammadex, a new generation neuromuscular blocker reversal agent, not having serious side effects as much as the classic reversals, such as cardiovascular side effects, is playing an important role in anesthesiology practice. In recent years, rocuronium-sugammadex combination is being included in the ECT practice extensively. In this paper, the usability of rocuronium-sugammadex combination as an alternative to succinylcholine has been revised.

    2008-01-01

    Full Text Available Background: Lumbar Puncture (LP is an invasive procedure frequently used to diagnose meningitis among the pediatric population. Neonates and infants have not routinely received local anesthesia prior to LP. Study Objective: To determine whether emergency medicine physicians and pediatricians use local analgesics on neonates and infants prior to performing an LP and to identify which local anesthetics, if any, were used. Methods: Prospective, cohort study of all infants, six months of age or less, that received an LP in the emergency department (ED or inpatient pediatric units for suspected meningitis during a period of year at a university tertiary care hospital. Results: A total sample population of 111 infants that received an LP within the study period. A control population of 42 adults received an LP. Only 40.4% (45/111 of the infants received local analgesia prior to LP: either 1% lidocaine, EMLA or a combination of the two. Infants were less likely to receive lidocaine or EMLA prior to LP compared to adult subjects (OR= 0.27; 95% CI0.12 to 0.62. No neonates that were less than one month of age received local procedural anesthesia by emergency medicine or pediatric physicians. ED physicians’ use of local anesthesia prior to LP increased with increasing age of the infant. The pediatricians in this study used local anesthesia prior to LP when the infant was at least five months of age. Discussion: The data objectively support recent literature regarding the under use or lack of use of analgesia prior to LP among neonates and infants. Local anesthetics should be used routinely without exception prior to performing an LP in the pediatric population.

    Thoracic surgery has become to be performed more safely by recent progress of operative method and anesthetic management. The surgery can be applicable for those patients who were formerly difficult for operation because of preoperative poor respiratory function, however, postoperative mortality and morbidity increase in such patients without appropriate perioperative management. Experienced anesthetic management can contribute to the risk reduction for these conditions. Since respiratory function which is injured by associated diseases is worsen by both thoracic surgery and general anesthesia, patients with coexisting respiratory diseases in particular need to be watched out intensively. Coherent risk management from preoperative to postoperative period becomes important. This is achieved by the comprehensive perioperative patient management which is consisted of the cooperation between the surgeon and the anesthetist, correct preoperartive evaluation, preoperative medical treatment with pulmonary rehabilitation, appropriate anesthetic management, and postoperative intensive care.

    Objective. Reporting of a rare case of postoperative submandibular gland swelling following craniotomy. Case Report. A 33-year-old male underwent resection for a brain tumor under general anesthesia. The tumor was resected via a retrosigmoid suboccipital approach and the patient was placed in a lateral position with his face down and turned to the right. Slight swelling of the right submandibular gland was observed just after the surgery. Seven hours after surgery, edematous change around the submandibular gland worsened and he required emergent reintubation due to airway compromise. The cause of submandibular gland swelling seemed to be an obstruction of the salivary duct due to surgical positioning. Conclusion. Once submandibular swelling and edematous change around the submandibular gland occur, they can worsen and compromise the air way within several hours after operation. Adequate precaution must be taken for any predisposing skull-base surgery that requires strong cervical rotation and flexion. PMID:26697254

For a pregnant woman with cardiac disease, the potential inability of the maternal cardiovascular system to contend with normal pregnancy-induced physiologic changes may produce deleterious effects on both mother and fetus. To determine the most frequent surgical indications of maternal and fetal mortality, we studied 15 cases of severe cardiac disease in pregnant women who required cardiac surgical procedures. Methods: In this descriptive study, fifteen pregnant women who underwent cardiac surgery were studied. Maternal age ranged from 27 to 36 years, and gestational age varied from 4 to 22 weeks. Most of the patients were in New York Heart Association Classes II and III. Opioid- based anesthesia with fentanyl citrate (50µ/kg or sufentanil (5µ/kg plus low dose of thiopental were used for the induction of anesthesia. During non-pulsatile cardio-pulmonary bypass, core temperature was between 28-36 °C, average CBP time was 61.2±22 min, average aortic cross-clamp time was 34.13±14 min, and mean pump pressure was maintained between 65-80 mmHg. Results: Ten patients had severe mitral valve disease (66.6%, three had aortic valve disease (20%, one had subvalvular aortic stenosis (6.7%, and the remaining one had left atrial myxoma (6.7%. There were five fetal deaths (33.3% and one maternal death (6.7%. Conclusion: It seems that open heart surgery in the first trimester is very hazardous for the fetus and may lead to fetal death. If possible, surgery should be carried out in the second trimester of pregnancy. The recommendations are simply guidelines because research data and clinical experience in this area are limited.

    This paper reports on a novel method for quantifying the cortical activity of a patient during general anesthesia as a surrogate measure of the patient's level of consciousness. The proposed technique is based on the analysis of a single-channel (frontal) electroencephalogram (EEG) signal using stationary wavelet transform (SWT). The wavelet coefficients calculated from the EEG are pooled into a statistical representation, which is then compared to two well-defined states: the awake state with normal EEG activity, and the isoelectric state with maximal cortical depression. The resulting index, referred to as the wavelet-based anesthetic value for central nervous system monitoring (WAV(CNS)), quantifies the depth of consciousness between these two extremes. To validate the proposed technique, we present a clinical study which explores the advantages of the WAV(CNS) in comparison with the BIS monitor (Aspect Medical Systems, MA), currently a reference in consciousness monitoring. Results show that the WAV(CNS) and BIS are well correlated (r = 0.969) during periods of steady-state despite fundamental algorithmic differences. However, in terms of dynamic behavior, the WAV(CNS) offers faster tracking of transitory changes at induction and emergence, with an average lead of 15-30 s. Furthermore, and conversely to the BIS, the WAV(CNS) regains its preinduction baseline value when patients are responding to verbal command after emergence from anesthesia. We conclude that the proposed analysis technique is an attractive alternative to BIS monitoring. In addition, we show that the WAV(CNS) dynamics can be modeled as a linear time invariant transfer function. This index is, therefore, well suited for use as a feedback sensor in advisory systems, closed-loop control schemes, and for the identification of the pharmacodynamic models of anesthetic drugs.

    Purpose: To find out whether in varicocele embolization the copolymer cyanoacrylate glue (NBCA-MS) has a better patient tolerance compared to the monomer n-butyl-2-cyanoacrylate (NBCA). Materials and methods: N = 112 insufficient spermatic veins (left sided N = 84, right sided N = 28) diagnosed in N = 83 adult males were prospectively randomized for blinded embolization with either NBCA N = 54 (Histoacryl) or with NBCA-MS N = 58 (Glubran2). Before, during and up to one week after embolization, patient discomfort was assessed by a standardized pain scale. Type, location and side of discomfort were noted. Statistical analysis was performed with the Mann–Whitney U-test, the McNemar test and the Fisher's exact test. Results: Embolization caused discomfort in N = 48/112 (43%) spermatic veins, comprising N = 26/54 (48%) in the NBCA group and N = 22/58 (38%) in the NBCA-MS group. During the week after embolization, the overall number of discomfort reports rose to N = 62/106 (59%), with an increase to N = 30/53 (57%) in the NBCA group and to N = 32/53 (60%) in the NBCA-MS group. The number of immediate grade 2 to 4 pain reactions was N = 22/112 (20%), and rose to N = 37/106 (35%) after one week. No difference in discomfort during embolization and at 1 week after treatment was noted. Characteristics, severity grading, and location of discomfort were similar in both NBCA groups, regardless the time point of observation. Conclusion: Discomfort after glue embolization of varicocele is a common side effect, which might evolve to pain. The assumed lower inflammatory reaction on NBCA-MS was not translated in an improved tolerance.

    Existing literature on learning in regional anesthesia broadly covers the rate of skill acquisition and the structure of educational programs. A complementary body of literature spanning psychology to medical education can be found describing skill acquisition in other fields. Concepts described in this literature have direct application to the teaching of regional anesthesia. This review introduces a selection of these complementary educational concepts, applying them to ultrasound-guided regional anesthesia skills education. Key educational concepts presented in this article can be divided into 3 sections, namely, how residents acquire manual skills, how tutors teach, and type of feedback.

    2014-01-01

    Full Text Available Anesthesia dolorosa is an uncommon deafferentation pain that can occur after traumatic or surgical injury to the trigeminal nerve. This creates spontaneous pain signals without nociceptive stimuli. Compression of the trigeminal nerve due to acoustic neuromas or other structures near the cerebellopontine angle (CPA can cause trigeminal neuralgia, but the occurrence of anesthesia dolorosa subsequent to acoustic tumor removal has not been described in the medical literature. We report two cases of acoustic neuroma surgery presented with anesthesia dolorosa along the trigeminal nerve distribution. The patients’ pain was managed with multidisciplinary approaches with moderate success.

    2016-03-01

    A significant number of anesthetics are performed outside of the operating room (OR). Despite the increased requirement for anesthesia services, the framework to perform the necessary preprocedural anesthesia assessments to optimize patients has not been uniformly developed. Performing anesthesia in non-OR locations poses significant and distinct challenges compared with the procedures in the OR. Anesthesiologists are faced with patients with increasingly complicated comorbidities undergoing novel, complex interventional procedures. With unique training in preoperative triaging, and an expertise in intraoperative and postoperative management of complex patients, anesthesiologists can contribute to greater efficiency and patient safety in the non-OR setting.

    Full Text Available BACKGROUND: We investigated the effects of a novel method of anesthesia combining propofol and volatile anesthesia on the incidence of postoperative nausea and vomiting in patients undergoing laparoscopic gynecological surgery. METHODS: Patients were randomly divided into three groups: those maintained with sevoflurane (Group S, n = 42, propofol (Group P, n = 42, or combined propofol and sevoflurane (Group PS, n = 42. We assessed complete response (no postoperative nausea and vomiting and no rescue antiemetic use, incidence of nausea and vomiting, nausea severity score, vomiting frequency, rescue antiemetic use, and postoperative pain at 2 and 24 h after surgery. RESULTS: The number of patients who exhibited a complete response was greater in Groups P and PS than in Group S at 0-2 h (74%, 76% and 43%, respectively, p = 0.001 and 0-24 h (71%, 76% and 38%, respectively, p < 0.0005. The incidence of nausea at 0-2 h (Group S = 57%, Group P = 26% and Group PS = 21%, p = 0.001 and 0-24 h (Group S = 62%, Group P = 29% and Group PS = 21%, p < 0.0005 was also significantly different among groups. However, there were no significant differences among groups in the incidence or frequency of vomiting or rescue antiemetic use at 0-24 h. CONCLUSION: Combined propofol and volatile anesthesia during laparoscopic gynecological surgery effectively decreases the incidence of postoperative nausea. We term this novel method of anesthesia "combined intravenous-volatile anesthesia (CIVA".

    Anesthesia information management systems (AIMS) are increasingly being implemented throughout the United States. However, little information exists on the implementation process for AIMS within ambulatory surgery centers (ASC). The objectives of this descriptive study are to document: 1) the phases of implementation of an AIMS at an ASC; and 2) lessons learnt from a socio-technical perspective. The ASC, within the Veterans Health Administration (VHA), has hosted an AIMS since 2008. As a quality improvement effort, we implemented a new version of the AIMS. This new version involved fundamental software changes to enhance clinical care such as real-time importing of laboratory data and total hardware exchange. The pre-implementation phase involved coordinated preparation over six months between multiple informatics teams along with local leadership. During this time, we conducted component, integration, and validation testing to ensure correct data flow from medical devices to AIMS and centralized databases. The implementation phase occurred in September 2014 over three days and was successful. Over the next several months, during post-implementation phase, we addressed residual items like latency of the application. Important lessons learnt from the implementation included the utility of partnering early with executive leadership; ensuring end user acceptance of new clinical workflow; continuous testing of data flow; use of a staged rollout; and providing additional personnel throughout implementation. Implementation of an AIMS at an ASC can utilize methods developed for large hospitals. However, issues unique to an ASC such as limited number of support personnel and distinctive workflows must be considered.

  1. Introduction of the carbon dioxide absorption method with closed circle breathing into anesthesia practice.

    Science.gov (United States)

    Foregger, R

    2000-07-01

    The circle breathing CO2 absorption system for use during acetylene anesthesia was described by Carl Gauss in 1924/1925. The apparatus was manufactured by Drägerwerk of Lübeck. A considerable number of publications on the apparatus employing the closed circle method of CO2 absorption appeared in the medical press soon thereafter. Later apparatus models, also built by Drägerwerk, were adapted for nitrous oxide-oxygen-ether anesthesia and introduced into practice by Paul Sudeck and Helmut Schmidt. Information about all this was transmitted to America through the German medical press, including the Draeger-Hefte. American anesthesia machine manufacturers began to develop closed circle CO2 absorbers several years later. Claims that the circle breathing CO2 absorption method was introduced into anesthesia practice by Brian Sword are not valid. PMID:10969391

    Objective: To observe the advantage of total intravenous anesthesia for transurethral resection of bladder tumor (TURBT). Methods: Sixty ASA Ⅰ-Ⅱ patients undergoing TURBT were randomly assigned to 2 groups. Spinal anesthesia with 0.75% pure bupivacaine (8-12 mg) was applied to patients in Group Ⅰ (n= 30). Patients in Group Ⅱ (n=30) received total intravenous anesthesia with continuous infusion of Propofol and Remifentanil; and a laryngeal mask was used to ensure the airway and ventilation. BP, HR, SPO2 and pertinent side effects were monitored and recorded. Results: The patients in group Ⅱ experienced more stable hemodynamics than those in group Ⅰ. Obturator nerve reflex was observed in 15 (50.0%) patients in Group Ⅰ, but none (0%) in Group Ⅱ (P<0.01). Conclusion: Total intravenous anesthesia with laryngeal mask is a safe, reliable, controllable and simple manual for patient undergoing TURBT.

    The sitting beach-chair position is regularly used for shoulder surgery and anesthesia may be induced in that position. We tested the hypothesis that the cardiovascular challenge induced by induction of anesthesia is attenuated if the patient is placed in a reclining beach-chair position....... Anesthesia was induced with propofol in the sitting beach-chair (n = 15) or with the beach-chair tilted backwards to a reclining beach-chair position (n = 15).

    A retrospective analysis was performed on a consecutive series of 60 cases divided into two groups given carotid endarterectomy (C.E.) for atherosclerotic disease. In the first group general anesthesia and barbiturate cerebral protection were employed; in group two, loco-regional anesthesia. Indications and risk factors were similar in the two groups; the surgical procedure was identical. The differences in the results are reported and factors contributing to cerebral protection or reduction in the risk of stroke are analyzed. The analysis indicates that loco-regional anesthesia for C.E. is a reliable method for detecting cerebral ischemia and guaranteeing cerebral protection by means of a temporary shunt when strictly necessary.

    Although bupivacaine for combined spinal-epidural anesthesia (CSEA) in cesarean section is widely used ,its optimal dose in spinal anesthesia for cesarean section is still difficult to determine. There are four methods in the literature to make maternal hemodynamic parameters more stable and to lower incidence of side-effects while providing equally effective anesthesia.The four methods include a low dose spinal anesthesia combined with epidural anesthesia, an adjusted dose of local anaesthetic for spinal anaesthesia according to body height and weight, epidural volume extension (EVE) by an epidural injection of physiological saline solution and a low-dose local anesthetic-opioid spinal anesthesia. The most optimal one among the 4 methocls are still worthy of further study.%布比卡因腰硬联合麻醉(combined spinal-epidural anesthesia,CSEA)在剖宫产中的应用较多,但其腰麻用于剖宫产术的最佳剂量较难确定,通过阅读文献发现有4种方法分别为给予小剂量腰麻,把腰麻限制在低位节段,通过硬膜外追加利多卡因来加强麻醉效果;根据身高与体重调节腰麻的剂量;通过硬膜外注射盐水来减少腰麻剂量;通过布比卡因腰麻复合阿片类药物来减少腰麻剂量,可使母体血液动力学相对稳定,副作用发生率低,麻醉效果好,但在这4种给药方法中,究竟哪一种能使剖宫产患者血液动力学最稳定、麻醉效果最好、副作用最少,还有待于进一步研究.

    Full Text Available This study was designed to investigate the influence of saline injections as epidural top-up on the sensory block duration, quality and hemodynamic effects of unilateral spinal anesthesia. The cases from ASA I-Il containing of 18-65 age group were randomly separated into three groups. For the purpose of unilateral spinal anesthesia, 6 mg 0.5% ‘heavy’ bupivacaine and for the purpose of epidural top-up, 10 mL saline were applied to the each patients of the groups. The study protocol was designed as:Ist group: Coming after the epidural catheter installation, unilateral spinal anesthesia was applied (n=20.IInd group: At first, unilateral spinal anesthesia was applied and after one minute, epidural top-up was done via the pre-installed epidural catheter (n=20.IIIrd group: At first the epidural catheter was installed and epidural top-up was applied. After one minute, unilateral spinal anesthesia was fulfilled (n=2O. Starting from the pre-anesthesic period, the hemodynamic data and following the anesthesia, the sensorial and motor block levels were recorded and evaluated.As the outcome of the inter-groups comparison of heart rate and mean arterial pressure, a statistically note-worthy differance was not determined; statistically significant but clinically acceptable hemodynamic changes were observed in intra-group evaluations, when the data was compared with control levels. The sensorial block levels were significantly higher in group II and significantly lower in group III.The application of 10 mL saline via epidural catheter 1 minute after the unilateral spinal anesthesia and remaining the patient leaning on the side of the extremity to be operated for 15 minutes improves the sensory block level of unilateral spinal anesthesia. It is determined that, for the lower extremity surgical operations with 1-1.5 hour estimated period, this method alone can be a worthwhile alternative.

    Background: Awareness and recall, though not common, are the major hazards of general anesthesia, especially in Cesarean section (C/S) because of the absence of benzodiazepine and opioids for a significant time during anesthesia. In this study, the Bispectral Index (BIS), end-tidal isoflurane, and hemodynamic parameters were examined to evaluate the depth of the routine general anesthetic technique in C/S. Methods: This study was carried out on 60 parturient patients undergoing elective C/...

    Objective:To observe the effect of remifentanil combined with propofol anesthesia on stress response, blood gas index in patients with laparoscopic cholecystectomy. Methods:A total of 88 patients with laparoscopic cholecystectomy were randomly divided into the observation group (46 cases) and the control group (42 cases). After anesthesia induction,the observation group was given remifentanil combined with propofol intravenous anesthesia for continuous anesthesia, and control group was given isoflurane and propofol. Stress response (TNF-αα, CRP, BG, COGT), blood gas index (PaO2, PCO2, PH value) before surgery, before anesthesia maintained, and after surgery between two groups were compared. Results: Before anesthesia maintained and after surgery, PaO2 and PCO2 levels of the two groups increased with before surgery (P0.05). pH value of the two groups showed no change before and after surgery. Before anesthesia maintained and after surgery, TNF-αα, CRP, BG, COGT of the two groups increased with before surgery (P0.05) at before anesthesia maintained. While to the end of surgery, these index of the control group was significantly higher than that in the observation group (P<0.05). Conclusions:Remifentanil combined with propofol anesthesia can make blood gas index stable as well as isoflurane combined with propofol anesthesia, but inhibit stress response more significantly.

    Full Text Available Objective: To compare the acceptability and effectiveness of topical and infiltration anesthesia for placement of mini-implants used as temporary anchorage devices. Methods: The sample comprised 40 patients, 17 males and 23 females, whose mean age was 26 years old and who were all undergoing orthodontic treatment and in need for anchorage reinforcement. Mini-implants were bilaterally placed in the maxilla of all individuals, with infiltration anesthesia on one side and topical anesthesia on the other. These 40 patients completed two questionnaires, one before and another after mini-implant placement and pain was measured through a visual analog scale (VAS. The data collected were analyzed using descriptive statistics and the measurements of pain were compared by means of the non-parametric test of Mann-Whitney. Results: It was found that 60% of patients felt more comfortable with the use of topical anesthesia for mini-implant placement; 72.5% of patients described the occurrence of pressure during placement of the anchorage device as the most unpleasant sensation of the entire process; 62.5% of patients felt more pain with the use of topical anesthesia. Conclusion: It was concluded that patients had less pain with the use of infiltration anesthesia, and also preferred this type of anesthetic.

    Objective:To evaluate retrospectively the effect of general anesthesia onDNA damage in the blood mononuclear cells (PBMCs) of surgical patients in order to provide evidence for a better nursing care during the procedure.Methods: Clinical charts of76 patients who underwent operation under general anesthesia and76 healthy control subjects with documented results of DNA damage extent inPBMCs from the single-cell gel electrophoresis(SCGE) or comet assay and serum contents of superoxide dismutase(SOD) and malondialdehyde(MDA)from biochemical analyses were reviewed. The percentage of comet PBMCs and tailDNAand serum contents of SOD and MAD were analyzed by student t-test.Results: Compared with healthy control subjects, generally anesthetized surgical patients had significantly higher % cometPBMCs and % tail DNA(P<0.05) and significantly lower serum concentrations ofSOD (P<0.05) and significantly higher serum concentrations ofMAD (P<0.05). Compared with levels before general anesthesia in surgical patients, % cometPBMCs, % tailDNA, and serum levels ofMADwere significantly higher (P<0.05 or0.01), and serum levels ofSOD were significantly lower (P<0.05), after general anesthesia.Conclusions: General anesthesia during surgery causes a certain degree of hypoxia and PBMC damage. Particular attention should be paid to monitoring and maintenance of blood oxygen saturation in patients undergoing surgery under general anesthesia.

    Objective: To observe changes of plasma catecholamine (CA) level in patients experiencing cholecystectomy under acupuncture anesthesia combined with epidural administration of small dose of anesthetics. Methods:33 cholecystectomy patients were randomly divided into acupuncture combined with epidural anesthesia (A) group (n = 11), acupoint-skin electrical stimulation combined with epidural anesthesia (B) group (n= 11 ) and simple epidural anesthesia (C) group (n= 11). Acupoints used were bilateral Zusanli (ST 36) and Neiguan (PC 6) and stimulated with parameters of frequency 2/15 Hz, intermittent waves, electric current 2~3 mA for group A and 13mA for group B. Extradural anesthetic administered was 1.5% Lidocaine 5 mL. Venous blood samples were collected one day before,NE of group A and B lowered in comparison with pre-operation, particularly group A (P <0.01), while in group C,plasma NE level increased slightly; plasma E of group A and B increased significantly compared with pre-operation (P levels recovered basically in comparison with those of one day before operation. It indicates that acupuncture or acupoint-skin electrical stimulation is capable of regulating sympathetic activity during epidural anesthesia. The anesthetic effec t has a closer relation with changes of plasma NE level rather than changes of plasma E or DA levels. C_onclusion:Acupuncture or acupoint-surface electrical stimulation combined with epidural anesthesia may be of reducing or releasing surgical operation generated stress response during cholecystectomy.

    Materials and Methods: In a private rural medical college, 150 patients were selected prospectively for laparoscopic cholecystectomy, under low-pressure (8mmHg pneumoperitoneum and under spinal anesthesia over a span of one and a half years. Injection bupivacaine (0.5% was used for spinal anesthesia. All ports were made in a head-down position to avoid hypotension. Shoulder pain was managed by reassurance as well as by diverting the attention and sedation in a few cases. Results: We successfully performed the operations in 145 patients without major complications. Spinal anesthesia was converted to general anesthesia in five patients due to severe shoulder pain. Age varied between 21 and 75 years. Duration of operation time (skin to skin was between 40 and 80 minutes. Twenty-nine patients complained of right shoulder pain. Most of them were managed by reassurance from the anesthetist and a few needed an injection of fentanyl along with midazolam. Conclusion: Laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum is feasible and safe under spinal anesthesia. Incidence of postoperative shoulder pain and complications are comparable with laparoscopic cholecystectomy under general anesthesia. [Arch Clin Exp Surg 2012; 1(4.000: 224-228
