Analgesic effects of transversus abdominis plane and quadratus lumborum blocks are not clinically meaningful for laparoscopic nephrectomy: systematic review and network meta-analysis.

ABSTRACT:

Background

Ultrasound-guided abdominal wall blocks are increasingly used to enhance postoperative analgesia in laparoscopic nephrectomy. Among these, the transversus abdominis plane (TAP) block and the quadratus lumborum (QL) block have emerged as promising techniques. However, no comprehensive review has yet compared the analgesic efficacy of these two regional approaches.

Methods

An extensive search was conducted across MEDLINE, Embase, Cochrane Library, Web of Science, and Google Scholar to identify randomized controlled trials comparing the postoperative analgesic effects of the TAP block, QL block, and systemic analgesia. The primary outcome was 24-hour opioid consumption, standardized to intravenous morphine milligram equivalents (MME). Secondary outcomes included post
