Brief Summary

This study aimed to assess the effectiveness of the ultrasound-guided interfascial injection approach with the subpectineal injection technique for obturator nerve block in bladder cancers undergoing transurethral resection of bladder tumor (TURBT) under spinal anesthesia.

Conditions

Bladder Neoplasm

Keywords

obturator nerve block; ultrasound guided block; bladder tumor

Outcome Measures

Primary Outcomes (1)

• Success rate of obturatr nerve block

  The success or fail of the obturator nerve block will be conformed using nerve stimulator. Detecting muscles twitch will br considered to be a fail.

  Peroperative period

Secondary Outcomes (4)

• Number of adductor muscle spazms

  Intraoperative period

• Sensory block

  30 minutes after the intervention

• Patient satisfaction

  Peroperative period

• Procedure time

  During the procedure

Study Arms (2)

Ultrasound guided interfascial obturator nerve block

ACTIVE COMPARATOR

In supine position, ultrasound probe will be placed on inguinal region, 2-3 cm below to the inguinal crease. Patients in this group will receive interfascial obturator nerve block under ultrasound guidance.

Procedure: Interfascial Injection

Ultrasound guided subpectineal obturator nerve block

EXPERIMENTAL

In supine position, the ultrasound probe will be placed on in inguinal region, 1-2 cm below to the inguinal crease to identiy the subpectineal area. Patients in this group will receive subpectineal obturator nerve block under ultrasound guidance.

Procedure: Subpectineal Injection
