Résumé
Quadratus lumborum block (QLB) has recently gained popularity for postoperative analgesia after cesarean delivery (CD) as it provides both visceral and somato-sensory blockade of the abdomen. Aim of this meta-analysis was to evaluate the analgesic potential of QLB after CD. Electronic database from inception to December 2019 was searched systematically for randomized-controlled trials comparing QLB with injection of inactive solution in women undergoing CD. Primary outcome was consumption of morphine at 24 h. Morphine consumption at 48 h, dynamic and static pain scores at various time intervals were the secondary outcomes studied. Seven trials met the inclusion criteria. Morphine consumption was reduced significantly with QLB in comparison to sham or no block at 24 h (mean difference [MD] - 9.84 mg; 95% confidence interval [CI] - 18.16, - 0.50; p = 0.04; I QLB significantly reduces opioid requirements in CD and may have analgesic effects lasting 24 h.
