Not yet recruiting

• Conditions: Malignant neoplasm of lateral wallof bladder, (2) ICD-10 Condition: N328||Other specified disorders of bladder,

• Registration Number: CTRI/2022/01/039492
• Lead Sponsor: Safdarjung Hospital and Vardaman Mahavir Medical College New Delhi India

Brief Summary

Patient assessed for eligibility, Preoperative assessement and prepration will be done, Written informed consent from patient/ guardian will be taken Patient will be shifted to operation theatre and monitors attached. Baseline vitals will be noted. Intravenous line established and i.v injection fentanyl 0.5 mcg/kg will be given to each patient. Randomisation into two groups- proximal group (P group) or distal (D group) will be done Ultrasound guided obturator nerve block will be performed by proximal or distal approach . Block performance time ,number of needle passes, complications will be noted. Patient will be monitored.Adductor muscle power will be assessed and graded after 15 minutes. spinal anesthesia will be given with 2.5 ml of 0.5% bupivacaine with 10 mcg fentanyl. After confirming the sensory blockade at T-10 level surgery will be started Success rate will be determined by the absence of adductor jerk/ spasm during the surgery. If any jerks are observed and leads to discontinuation of surgery , it will be noted and general anaesthesia will be given. Surgeon satisfaction will be noted at end of surgery

Primary Outcome Measures

Name	Time	Method
To compare the success rate of proximal versus distal approach of ultrasound guided obturator nerve block for prevention of adductor spasm in patients undergoing transurethral resection of lateral wall bladder tumour under spinal anaesthesia by the absence of adductor muscle jerk during the surgery.	During surgery

Secondary Outcome Measures

Name	Time	Method
To compare proximal versus distal approach of ultrasound guided obturator nerve block in patients undergoing transurethral resection of lateral wall bladder tumour under spinal anaesthesia with respect to-	Adductor muscle power after the block
