M-TAPA versus port-site local anesthetic for pain control after pediatric laparoscopic abdominal surgery

Official title: The Analgesic Efficacy of Modified Thoracoabdominal Nerve Block Through Perichondrial Approach for Laparoscopic Abdominal Surgery in Children: Randomized Controlled Trial

Run by Kasr El Aini Hospital · NCT07540689 · Data updated 2026-11-12

This trial will test whether an ultrasound-guided M-TAPA nerve block reduces postoperative pain compared with standard port-site local anesthetic injections in children aged 1–7 having laparoscopic abdominal surgery.

Is this trial a fit for you?

Likely a good fit

Children aged 1–7 years with ASA physical status I–II who are scheduled for elective laparoscopic abdominal surgery and whose parents consent to participation.

Probably not a fit

Children with bleeding disorders (INR >1.5 or platelets <50,000), known allergy to local anesthetics, infection at the injection site, or parental refusal are excluded and would not receive benefit from this protocol.

What this trial studies

This single-center randomized trial will enroll 60 children aged 1–7 undergoing elective laparoscopic abdominal surgery under general anesthesia. Before incision participants are randomly assigned to either port-site infiltration with 0.17 mL/kg of 0.25% bupivacaine (up to 2 mg/kg) at the three port sites or bilateral ultrasound-guided M-TAPA with 0.25 mL/kg of 0.25% bupivacaine per side. Postoperative pain scores and analgesic (rescue opioid/nonopioid) requirements will be recorded, and patients will be monitored for local anesthetic–related complications. The study compares analgesic efficacy and safety of the two techniques in the immediate postoperative period.

Why it matters

Potential benefit: If successful, M-TAPA could provide better or longer-lasting postoperative pain relief and reduce the need for opioids after pediatric laparoscopic abdominal surgery.

How similar studies have gone: Related abdominal plane blocks such as TAP and subcostal TAP have shown analgesic benefit in pediatric patients, but M-TAPA itself has limited pediatric trial data and is less well established.
