Background:Selective obturator nerve blockade (ONB) is an effective option to prevent adductor spasm during transurethral resection of bladder tumors (TURBT) involving the lateral wall under spinal anesthesia (SA). The classic approach is less popular as the obturator nerve is deep seated and associated with vascular injury. The inguinal approach was described as a safer alternative. This randomized clinical study was undertaken to compare the ease of block, the success rate and complications of the classic pubic and superficial inguinal approach for ONB.Materials and Methods:A total of 30 patients scheduled to undergo TURBT under SA were administered bilateral ONB. Inguinal approach recently described by Choquet was performed on one side and classic approach described by Labat was performed on the other side in random order using a nerve stimulator. The ease of block, success rate (number of attempts to accomplish the block) and complications were noted and compared between both the approaches. Chi-square analysis was performed to compare the ease of approach of the two techniques. Non-parametric analyses using Mann Whitney test was used to compare the number of attempts to accomplish the block in each approach. A value of P < 0.05 was considered statistically significant.Results:The ease of block (P = 0.09) and the median number of attempts to accomplish the block (P = 0.45) were comparable between the two approaches. The incidence of vascular injury was higher in classic approach (P = 0.056).Conclusions:Inguinal approach is a useful alternative to classic approach block for patients undergoing TURBT under SA.
Background: Laminectomy is associated with considerable postoperative pain. Providing analgesia locally in the area of surgical trauma, with minimal systemic side effects, is an attractive option and has become an integral part of multimodal analgesia. The objective of this study was to assess and compare the effectiveness and safety of local infiltration of bupivacaine and bupivacaine plus magnesium sulphate for postoperative analgesia in patients undergoing lumbar laminectomy. Materials and Methods: Sixty adult patients of the American Society of Anaesthesiologists (ASA) class 1 and 2 were randomly allocated into two groups, comprising 30 patients in each group. After the completion of lumbar laminectomy, the study drug was locally infiltrated into the paravertebral muscles on either side. Group bupivacaine with magnesium (BM) was given 20 ml of 0.25% bupivacaine with 500 mg of magnesium sulphate (constituted with normal saline); and Group bupivacaine (B) was given 20 ml of 0.25% bupivacaine constituted with normal saline. Postoperative visual analogue scale (VAS) pain scores at 1, 2, 4, 6, 8, 12 and 24 hours; rescue analgesia, the time to first analgesic consumption, degree of overall patient satisfaction and side effects were recorded. Comparison of continuous data between groups was done using independent T-test. Comparison of nominal data was done using Chi-square analysis and ordinal data using Mann-Whitney test. A P value less than 0.05 was considered significant. Results: Time to first analgesic consumption was significantly longer in BM group (7.78 ± 1.350 hours) compared to B group (4.62 ± 0.997 hours) (P < 0.0001). The consumption of Tramadol was significantly higher in B group (202.5 ± 76.9 mg) compared to BM (117.5 ± 63.4 mg) (P < 0.0001). The degree of overall satisfaction with postoperative pain management on a 4-point satisfaction scale was better in BM group (2.77 ± 0.626) compared to B group (2.0 ± 0.587) (P < 0.001). Conclusion: Wound infiltration with bupivacaine and magnesium sulphate provided better pain control and analgesic effect was more significant, providing effective and safe postoperative analgesia in patients undergoing laminectomy surgeries.
Maxillary block along with greater and lesser occipital nerve block is an effective alternative to scalp block for craniotomy and has longer duration of analgesia.
Diabetes mellitus is the most common medical condition and with increased awareness of heath and related issues, several patients are getting diagnosed with diabetes. The poor control of sugar and long-standing status of disease affects the autonomic system of body. The autonomic nervous system innervates cardiovascular, gastrointestinal, and genitourinary system, thus affecting important functions of the body. The cardiovascular system involvement can manifest as mild arrhythmias to sudden death. Our search for this review included PubMed, Google Search and End Note X6 version and the key words used for the search were autonomic neuropathy, diabetes, anesthesia, tests and implications. This review aims to highlight the dysfunction of autonomic system due to diabetes and its clinical presentations. The various modalities to diagnose the involvement of different systems are mentioned. An estimated 25% of diabetic patients will require surgery. It has been already established that mortality rates in diabetic patients are higher than in nondiabetic patients. Hence, complete workup is needed prior to any surgery. Diabetic autonomic neuropathy and its implications may sometimes be disastrous and further increase the incidence of in hospital morbidity and mortality. Overall, complete knowledge of diabetes and its varied effects with anaesthetic implications and careful perioperative management is the key guiding factor for a successful outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
