Abstract: Objective Comparing obturator nerve reflex in different anesthesia,to investigate the incidence of obturator nerve reflex in transurethral resection of bladder tumor.Methods A total of 160 patients with lateral wall of bladder tumors were included,who required a TURBT,were randomly divided into four groups:general anesthesia group (group G),combined spinal-epidural anesthesia group (group C),combined spinal-epidural anesthesia compounding intravenous anesthesia group (group V),combined spinal-epidural anesthesia compounding obturator nerve block group (group O),n =40 in each group.The incidence of obturator nerve reflex was recorded.Results Incidence of obturator nerve reflex in group O (7.5％) was lower than in group C (32.5％,P=0.005) and group V (40.0％,P=0.001).There was no significant difference between group G (5.0％) and group O (P =0.644).Conclusion Both combined spinal-epidural anesthesia with obturator nerve block and general anesthesia can effectively prevent obturator nerve reflex.
