Analgesic Effect of Ultrasound Guided Quadratus Lumborum Block Application After Laparoscopic Cholecystectomy Surgery

Laparoscopy is frequently used today for intraabdominal operations. Laparoscopic procedure has become the treatment of choice for many patients with symptomatic cholelithiasis. Patients undergoing laparoscopic cholecystectomy suffer from acute postoperative pain, despite a multimodal analgesic regime. This is a randomised controlled trial efficay of the Quadratus Lumborum (QL) Block in terms of analgesic efficacy in patients who undergo laparoscopic cholecystectomy.
