Sacral ESP Block to Help Pain After Pilonidal Sinus Surgery

Official title: Evaluation of the Efficacy of Ultrasound-Guided Sacral Erector Spinae Plane Block in Postoperative Analgesia Management in Patients Undergoing Pilonidal Sinus Surgery

Run by Medipol University · NCT07534488 · Data updated 2026-11-12

This study tests whether an ultrasound-guided sacral erector spinae plane (ESP) block after pilonidal sinus surgery can reduce pain and opioid use.

Is this trial a fit for you?

Likely a good fit

Adults undergoing elective pilonidal sinus surgery with ASA I-II status.

Probably not a fit

Patients with contraindications to regional anesthesia or local anesthetics, or those unlikely to benefit from regional analgesia.

What this trial studies

This randomized, prospective study compares two groups of patients undergoing pilonidal sinus surgery under general anesthesia: one receiving a sacral ESP block with local anesthetic after surgery and before extubation, and a control group receiving standard postoperative analgesia. Outcomes include need for rescue analgesics, total opioid consumption, pain scores, and side effects. The trial uses computer randomization and focuses on postoperative analgesia quality and safety. Enrollment is limited to adults with ASA I-II undergoing elective surgery, excluding those with contraindications to local anesthetics or opioids or with bleeding risk or infection at the block site.

Why it matters

Potential benefit: If successful, the sacral ESP block could provide better postoperative pain control and reduce opioid requirements after pilonidal sinus surgery.

How similar studies have gone: Previous regional anesthesia techniques have shown pain relief benefits in similar surgeries, suggesting potential effectiveness for sacral ESP blocks, though this specific approach is being evaluated.
