A Comparison of Ultrasound Guided Versus Ultrasound with Nerve Stimulation Technique for Obturator Nerve Block in Transurethral Resection of Bladder Tumour
Journal Title: Indian Journal of Anesthesia and Analgesia - Year 2018, Vol 5, Issue 4
Abstract
Introduction: The aim of the study was to compare the effectiveness of two different techniques in blocking obturator nerve (ON) and adductor spasm during transurethral resection of bladder tumor (TURBT). Methodology: We designed a prospective, randomized, double-blind study, in which fifty patients with American Society of Anesthesiologists Status II and III were scheduled to undergo TURBT for lateral and posterolateral bladder wall tumor were. Group I (ultrasound only group, n = 25) patients received 4 ml of bupivacaine 0.5% each at anterior, and posterior division of ON under real-time US visualization and Group II (ultrasound-nerve stimulation group, n = 25) received the same amount of bupivacaine 0.5% for each division using US-guidance with nerve stimulation-assisted technique. Block success and performance time and complications were measured along with patient and surgeon satisfaction into two groups. We did two sample independent t-test and Pearson’s Chi-square/Fisher’s exact test. Results: A success rate of 88% was achieved in Group II as compared to 70% in Group I with increased block performance time in Group II (5min) versus (3 min) in Group I. A better patient and surgeon satisfaction were seen in Group II with combination of US and nerve stimulation technique. No complications were encountered. Conclusion: We conclude that both techniques are safe and easy to perform; however, nerve stimulation along with US results in a higher success rate.
