    Abstract

    BACKGROUND: Ultrasound-guided (US) transversus abdominis plane (TAP) block is commonly utilized as part of a multi-modal approach for postoperative pain management. This study seeks to determine whether laparoscopic-guided TAP blocks are as effective as US-guided TAP blocks among pediatric patients.METHOD: In this prospective, randomized controlled trial, pediatric patients undergoing laparoscopic procedures were randomly assigned to one of two treatment arms: US-guided TAP block (US-arm) or laparoscopic-guided TAP block (LAP-arm). Primary outcome was PACU pain scores. Secondary outcomes included PACU opioid consumption, block completion time and block accuracy.RESULTS: Twenty-five patients were enrolled in each arm. In the LAP-arm, 59% of blocks were in the transversus abdominis plane compared to 74% of TAP blocks in the US-arm (p=0.18). Blocks were completed faster in the LAP-arm (2.1±1.9vs. 7.9±3.4min, p<0.001). The average highest PACU pain score was 3.4±3.1 for the LAP-arm and 4.3±3.8 for the US-arm (p=0.37). Overall PACU pain scores and opioid consumption were similar between the groups (1.2±1.3vs. 1.6±1.6, p=0.24; 2.2±5.8vs. 0.9±1.4MME, p=0.26).CONCLUSION: Laparoscopic TAP blocks have equivalent efficacy in post-operative pain scores, narcotic use, and tissue plane accuracy as compared to US-guided TAP blocks. They are also completed faster and may result in less operating room and general anesthetic time for the pediatric patient.
