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.

Conditions

  • Cancer of Bladder

Interventions

DRUG

Obturator block

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.
