Comparison of Obturator Nerve Blockade and Neuromuscular Blockade for the Prevention of Adductor Spasm in Patients Undergoing Transurethral Resection of Bladder Tumors.
In Brief
A Phase 4 clinical trial evaluating Obturator block and Neuromuscular block for Cancer of Bladder. Completed, enrolled 60 participants across 1 site.
Detailed Summary
Patients diagnosed with posterolateral bladder tumors will be invited to participate in the study. Subjects will be randomized to receive an ultrasound-guided obturator block or a neuromuscular blocking agent after the induction of general anesthesia in an attempt to block the obturator reflex during surgery.
Study Details
Timeline
Interventions
Subjects allocated to the obturator block group will be monitored for the incidence of block and procedure-related adverse events. In addition to clinical observation, a Nerve Integrity Monitor (Medtronic) will be used to detect adductor spasm using continuous electromyography. Electrodes will be placed on the thigh to objectively detect and record instances of adductor spasm. One hour after arrival to post-anaesthesia care unit (PACU) or when discharge criteria are met (whichever comes first), repeat dynamometer measurements and TUG tests will be performed. Patients will be called 24-48 hours post procedure to inquire about falls or evidence of nerve injury, as well as patient satisfaction.
