Ultrasound-guided pudendal nerve block for pain relief after hemorrhoid surgery
Effects of Ultrasound-guided Pudendal Nerve Block on Postoperative Pain and Quality of Recovery in Patients Undergoing Hemorrhoidectomy
This study is testing if a special pain relief technique using ultrasound can help people feel less pain and use fewer opioids after hemorrhoid surgery.

What this trial studies
This clinical trial investigates the effectiveness of ultrasound-guided pudendal nerve block in reducing postoperative pain and opioid consumption in patients undergoing Ferguson hemorrhoidectomy. Participants will be randomly assigned to receive either the nerve block with ropivacaine or a placebo saline solution immediately after surgery. All patients will also receive standard postoperative pain management, including intravenous patient-controlled analgesia, NSAIDs, and acetaminophen. Pain levels, opioid use, recovery quality, patient satisfaction, and any complications will be monitored at various intervals post-surgery.
Who should consider this trial
Good fit: Ideal candidates are adults aged 20 to 65 with symptomatic grade III or IV hemorrhoids undergoing surgery under spinal anesthesia.
Not a fit: Patients with allergies to local anesthetics, obesity (BMI ≥ 30), or those who are pregnant may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could significantly reduce postoperative pain and opioid use for patients after hemorrhoid surgery.
How similar studies have performed: Previous studies have shown promising results with similar nerve block techniques for postoperative pain management, suggesting potential success for this approach.
