Quadratus Lumborum Block Reduced Postpartum Uterine Pain After Virginal Childbirth

Chang Gung Memorial Hospital66 enrolled

Overview

With the continuous advancement of ultrasonic technology, nerve block in which drugs are injected into the periphery of the target nerve through ultrasonic guidance has become the mainstream method for postoperative pain control. The quadratus lumborum nerve block has been effectively and safely used in abdominal surgery (such as laparotomy, caesarean section, etc.), effectively reducing postoperative wounds and visceral pain. There is no research on the use of quadratus lumborum nerve block to control the pain of natural postpartum uterine contractions in the current literature, so the purpose of this experiment is to explore whether the quadratus lumborum nerve block can effectively reduce the pain of uterine contractions after vaginal delivery.
