Review Meta Analysis
Quadratus lumborum block for postoperative analgesia after cesarean delivery: A systematic review with meta-analysis and trial-sequential analysis.
The aim of this study was to investigate the analgesic efficacy of Quadratus lumborum block (QLB) versus controls, transversus abdominis plane (TAP) block and neuraxial morphine, or when added to neuraxial morphine in women undergoing cesarean delivery. ⋯ QLB improves post-cesarean delivery analgesia in parturients not receiving neuraxial morphine. Addition of QLB to parturients receiving neuraxial morphine has no significant analgesic benefit. Insufficient data are available to draw firm conclusions of QLB compared to TAP blocks or neuraxial morphine.
