An interventional study of quadratus lumborum nerve block (ropivacaine ) and quadratus lumborum nerve block (normal saline) in Quadratus Lumborum Nerve Block, Postpartum Cramping and Vaginal Delivery, sponsored by Chang Gung Memorial Hospital. Completed at 1 site in Taiwan. Open to female participants aged 20 Years and older. Per ClinicalTrials.gov, last updated 2024-03-15.

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.
Exclusion Criteria:
The subjects would have quadratus lumborum nerve block group with injection of local anesthetic (Ropivacaine) after vaginal delivery.
Procedure: quadratus lumborum nerve block (ropivacaine )
The subjects would have quadratus lumborum nerve block with normal saline after vaginal delivery.
Procedure: quadratus lumborum nerve block (normal saline)
