Official title: Outcomes for Anesthesiologist-Led Care of Analgesic Protocol in Anorectal Surgery

Run by China-Japan Friendship Hospital · NCT06015165 · Data updated 2026-11-12

This study tests whether having an anesthesiologist manage pain after complex anorectal surgery helps patients feel better and more satisfied compared to having the surgeon handle pain management.

Is this trial a fit for you?

Likely a good fit

Probably not a fit

Patients with a history of severe asthma, opioid abuse, or significant liver or renal dysfunction may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This open, prospective, parallel-group, randomized controlled trial aims to evaluate the effectiveness and safety of anesthesiologist-led postoperative analgesia compared to surgeon-led analgesia in patients undergoing complex anorectal surgery under general anesthesia. Patients will be randomly assigned to either the anesthesiologist-led group or the surgeon-led group, both receiving general anesthesia and multi-modal analgesia. The study will assess pain management outcomes, quality of life, and patient satisfaction over a follow-up period after surgery. The goal is to establish a more effective analgesia protocol for managing postoperative pain in this patient population.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management and patient satisfaction after anorectal surgery.

How similar studies have gone: Other studies have shown promising results with anesthesiologist-led analgesia approaches, indicating potential for success in this novel application.
