Effects of multimodal analgesia with combined quadratus lumborum block on enhanced recovery after Kasai portoenterostomy in infants with biliary atresia: a retrospective cohort study.

In infants undergoing Kasai surgery for biliary atresia, multimodal analgesia combined with quadratus lumborum block was associated with faster extubation, reduced intraoperative opioid exposure, improved postoperative pain control, and a lower incidence of postoperative nausea and vomiting.

This strategy may provide an effective and safe perioperative analgesic option for this vulnerable population.
