Summary

Evaluation of the effectiveness of Anterior Quadratus Lumborum Block at the lateral supra-arcuate ligament under laparoscopic direct vision compared to local infiltration anesthesia for postoperative analgesia after laparoscopic renal surgery in patients.A randomized controlled trial involving 66 patients undergoing laparoscopic renal surgery will assign them randomly to an experimental group or a control group.The patients in experimental group will receive Anterior Quadratus Lumborum Block at the lateral supra-arcuate ligament under laparoscopic direct vision.The patients in control group will receive local infiltration anesthesia.The primary outcome measure is the cumulative consumption of intravenous morphine equivalents at postoperative 24 hours.The secondary outcomes include the cumulative consumption of intravenous morphine equivalents at postoperative 2, 4, 6, 12 and 48 hours, Numeric Rating Scale(NRS) score at rest and during activity (coughing) at postoperative 2, 6, 24 and 48 hours, Global Comfort Questionnaire(GCQ) Comfort Status Scale Score, Quality of Recovery-15(QoR-15) Postoperative Recovery Scale Score, time of the first press on the Patient-Controlled Analgesia pump, nausea, vomiting, skin itching, drowsiness, or other adverse reactions, regional anesthesia-related complications such as local anesthetic toxicity and length of postoperative hospital stay after surgery.

Conditions

  • Postoperative Pain
  • Analgesia
  • Quadratus Lumborum Block
  • Laparoscopic Renal Surgery

Interventions

PROCEDURE

Anterior Quadratus Lumborum Block at the lateral supra-arcuate ligament under laparoscopic direct vision

The urologists find the inner arcuate ligament. The scalp needle is inserted from the midpoint of the lower edge of the inner or outer arcuate ligament towards the head to the dorsal side of the diaphragm. After withdrawing without blood, air, or cerebrospinal fluid, 2 ml of normal saline is first administered to observe the fluid spreading towards the head Then, 20 ml of 0.375% ropivacaine hydrochloride injection is administered.

PROCEDURE

Local infiltration anesthesia

The urologists give local infiltration anesthesia with 20 ml of 0.375% ropivacaine hydrochloride injection.
