Background and Aims The activation of the obturator nerve during transurethral resection of bladder tumors(TUR-BT) may result in unintentionally leg move known as the ‘obturator reflex’(leg jerking).It is better to avoid this condition because it might lead to a number of issues. In this study, we compared the effectiveness of obturator nerve block with different anesthetic solutions.

Methods In this study randomly assigned were, 40 patients scheduled for TUR-BT. Ultrasound-guided obturator nerve block was given with lidocaine 2%10ml and bupivacaine 0.5%5ml (Group I) or lidocaine 1%10ml and bupivacaine 0.5%5ml (Group II) by single injections (n=20 in each group).The length of the process in both groups was noted since an adductor spasm may make it more challenging; so were the time for obturator block performance, the severity of the motor blockade, and the length of the procedure.Throughout the procedure, the surgeon’s level of satisfaction was observed.The patient‘s satisfaction and any problems that might have occurred were also recorded.

Results Block performance time between groups was similar. The onset time until nerve blockade was 7.3±4 minutes for group I and 12±3 minutes for group II. The ease of access for the two groups was similar. The characteristics of the obturatorius nerve block are presented in table 1.

Conclusions Our research confirms a significant difference in onset time and surgeon satisfaction when obturatorius motor nerve blockade was performed using different anesthetic solutions.The beginning of action and the surgeon’s satisfaction are the primary issues in this treatment because the length of the blockade is not of importance.
