No review or meta-analysis exists to elucidate the efficacy and safety of quadratus lumborum block (QLB) on the pain intensity, opioid requirement, and mobilization in patients undergoing hip surgery. This systematic review and meta-analysis of randomized controlled trials were designed to compare QLB with no block or placebo (without other nerve/plexus blocks) for patients undergoing hip surgery. ⋯ There is moderate evidence that QLB employment in hip surgery produces significant reduction in pain scores and opioid consumption within 24 hours. QLB appears to be an appropriate option for postoperative analgesia after hip surgery.
