Obturator Nerve Blockade vs. Neuromuscular Blockade for the Prevention of Adductor Spasm in Patients Undergoing Transurethral Resection of Bladder Tumors: A Randomized Controlled Trial

Abstract Background The obturator nerve runs along the posterolateral walls of bladder and electrosurgical stimulation in this region can result adductor spasm which occur suddenly unexpectedly with potentially catastrophic results. Methods Sixty patients were prospectively randomized to receive either a single-injection ultrasound-guided block (ONB) or intravenous rocuronium after induction general anesthesia (i.e., neuromuscular [NMB]). primary objective was compare incidence during tumor resection when ONB NMB used. Secondary objectives included assessment fall risk adverse events. Results Five group six had nonlateral wall lesions. One patient suffered cardiac arrest anesthesia. Of remaining 48 patients, (10.2%) experienced spasm. Most these (5/24, 20.8%), only one (1/24, 4.2%) experiencing reflex group; difference not statistically significant (P=0.19). Patients greater decrease mean hip strength. Our study population found be at high falls before surgery. There no differences Timed Up Go test, time perform test increasing both groups. Conclusions Both techniques are safe efficacious for preventing data experience suggest that is relatively easy should considered tumors.
