A Randomized, Double-Blind Trial Comparing Pudendal Block Versus Sacral ESP for Ambulatory Hemorrhoidectomy
Status: Recruiting
Location: See location...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
The goal of this clinical trial is to learn if the sacral erector spinae plane block can provide equal or better pain control than the pudendal nerve block in adults undergoing hemorrhoid surgery. The main question is: Which block offers more effective analgesia and faster recovery?

Treatments
Active_comparator: Pudendal block
Patients in the control group will receive an ultrasound-guided bilateral pudendal nerve block with 20 mL of 0.75% ropivacaine and a sacral ESP block with 20 mL of normal saline. Blinding is ensured by the double block procedure
Experimental: Sacral ESP block
Patients in the intervention group will receive an ultrasound-guided sacral ESP block with 20 mL of 0.75% ropivacaine and a bilateral pudendal nerve block with 20 mL of normal saline.
