The Analgesic Efficacy of M-TAPA for Laparoscopic Abdominal Surgery in Children

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

This investigation aims to assess the efficacy of M-TAPA in children undergoing laparoscopic abdominal surgery.

Sixty pediatric patients undergoing laparoscopic abdominal surgery under general anesthesia will be enrolled in this single-center study. Preoperatively, participants will be randomly assigned to receive either port-site local anesthetic infiltration or M-TAPA.

Sixty pediatric patients undergoing laparoscopic abdominal surgery under general anesthesia will be enrolled in this single-center study. Preoperatively, participants will be randomly assigned to a port site local anesthetic infiltration. or M-TAPA.

1. port-site local anesthetic infiltration Before the skin incision, the surgeon will inject 0.17 mL/kg of 0.25% bupivacaine (up to 2 mg/kg) via infiltration into the skin, subcutaneous tissue, and muscle fascia at the three laparoscopic ports.
2. M-TAPA. Before skin incision, Ultrasound will be used to perform bilateral M-TAPA.0.25 mL/kg of 0.25% bupivacaine will be administered at each side.
