Summary

The goal of this clinical trial is to investigate the effects of ultrasound-guided pudendal nerve block on postoperative pain, opioid consumption, and quality of recovery in patients receiving Ferguson hemorrhoidectomy.

Detailed description

Patients who have symptomatic hemorrhoids undergoing Ferguson hemorrhoidectomy under spinal anesthesia will be randomized to receive bilateral ultrasound-guided pudendal nerve block with 0.5% ropivacaine or normal saline immediately after surgery. In addition, intravenous patient controlled analgesia, NSAIDs, and acetaminophen will be used in all participants for postoperative pain control. Postoperative pain on numerical rating scale (NRS), opioid consumption, quality of recovery (QOR-15), patient's satisfaction, and complications will be recorded at 6, 12, 24, 48 hours and 7 days after surgery.

Conditions

• Hemorrhoids
• Postoperative Pain
