Femoral and Sciatic Nerve Blocks Added to Obturator Nerve Block for Prevention of Obturator Reflex
Comparison of the Efficacy of Femoral and Sciatic Nerve Blocks Added to Obturator Nerve Block in Preventing the Obturator Reflex
This prospective, randomized controlled study aims to evaluate whether adding femoral and sciatic nerve blocks to obturator nerve block improves the prevention of obturator reflex during transurethral resection of bladder tumors under spinal anesthesia.
Ninety patients will be randomly assigned to three groups: obturator nerve block alone, obturator plus femoral nerve blocks, or obturator plus femoral and sciatic nerve blocks. Adductor muscle contractions, surgeon satisfaction, procedure duration, and complications will be evaluated.

상세 설명
This single-center, prospective, randomized controlled study will include 90 patients aged 18-90 years with American Society of Anesthesiologists (ASA) physical status I-III who are scheduled for transurethral resection of unilateral lateral bladder wall tumors under spinal anesthesia.
Eligible patients will be randomly allocated into three groups of 30 patients each:
Group 1: Obturator nerve block (ONB) alone.
Group 2: Obturator nerve block combined with femoral nerve block (ONB + FNB).
Group 3: Obturator nerve block combined with femoral and sciatic nerve blocks (ONB + FNB + SNB).
The nerve blocks will be performed using ultrasound guidance according to the study protocol.
During surgery, the occurrence and severity of adductor muscle contractions associated with the obturator reflex will be recorded. Contractions will be classified as absent, mild, or severe according to their interference with the surgical procedure. The total number of contractions will also be documented.
Additional assessments will include block procedure duration, surgical duration, surgeon satisfaction using a 0-10 numerical scale, conversion to general anesthesia, bleeding, bladder injury, perforation, blood transfusion, and complications related to the nerve blocks.
The study aims to determine whether adding femoral and sciatic nerve blocks to obturator nerve block improves the prevention of obturator reflex during transurethral bladder tumor resection.
