Ultrasound-guided TAP and rectus sheath nerve blocks to improve recovery after open inguinal hernia repair.

Official title: Effect of Medial Transversus Abdominis Plane (TAP) Block and Rectus Sheath (RS) Block on Inguinal Hernia Surgery Recovery, a Prospective Randomized Double-blind Study (PRO-RSTAP)

Run by Tampere University Hospital · NCT07423910 · Data updated 2026-11-12

This trial will test whether ultrasound-guided transversus abdominis plane (TAP) and/or rectus sheath (RS) nerve blocks reduce opioid use and speed recovery in adults having open unilateral inguinal hernia repair.

Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) scheduled for elective unilateral open inguinal hernia repair who can provide informed consent are the intended participants.

Probably not a fit

Patients undergoing emergency, bilateral, or recurrent hernia surgery, or those with contraindications or allergies to regional anesthesia, are unlikely to qualify or derive benefit.

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

What this trial studies

The PRO-RSTAP trial randomizes adults undergoing elective unilateral open inguinal hernia repair into four groups in a 2×2 factorial, double-blind design: combined TAP and RS blocks, TAP only, RS only, or placebo blocks alongside standard perioperative care. Blocks are performed under ultrasound guidance and the primary outcome is total perioperative opioid consumption measured as intravenous morphine equivalents. Secondary outcomes include postoperative pain scores, need for rescue analgesia, postoperative nausea and vomiting, time to discharge, and unplanned hospital admission. The trial is conducted at Tampere University Hospital with standardized anesthesia and follow-up protocols.

Why it matters

Potential benefit: If effective, these nerve blocks could lower opioid requirements, reduce pain and nausea, and help patients go home sooner after hernia repair.

How similar studies have gone: Previous trials of TAP or rectus sheath blocks in abdominal surgery have shown reduced opioid use and pain, but the combined TAP+RS approach for open inguinal hernia is less well established.
