M‑TAPA versus TAP block for pain after one-sided open inguinal hernia repair

Is this trial a fit for you?

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

What this trial studies

Adults scheduled for elective unilateral open inguinal hernia repair at a single center will be assigned to receive either an ultrasound‑guided M‑TAPA block or an ultrasound‑guided transversus abdominis plane (TAP) block before surgery. Blocks are performed in a block room with light sedation (1–2 mg IV midazolam) and standard aseptic technique. For the M‑TAPA group 20 ml of 0.25% bupivacaine is injected unilaterally at the costochondral angle under ultrasound guidance, while the TAP group receives a standardized ultrasound‑guided TAP injection per institutional technique. Postoperative pain scores and analgesic consumption will be recorded to compare the two approaches.
