Posteromedial quadratus lumborum block versus wound infiltration after caesarean section: A randomised, double-blind, controlled study.

Background: Reducing pain and minimising the use of opioids after caesarean section are crucial to enhancing maternal recovery and promoting mother-newborn interaction. Various techniques have been implemented to improve analgesia. We compared the analgesic efficacy of posteromedial quadratus lumborum block with that of wound infiltration following elective caesarean section.
