The quadratus lumborum block has been found to reduce pain after cesarean delivery. This study aimed to evaluate the analgesic effect of an ultrasound-guided transmuscular quadratus lumborum (TQL) block in reducing opioid consumption in the first 24 hours following cesarean delivery. The authors hypothesized a TQL block with ropivacaine would result in a minimum relevant difference of 50% reduction in opioid consumption during the first 24 hours compared with a TQL block with saline placebo.
