Clinical trial
Ultrasound-guided Quadratus Luborum Block Using Bupivacaine Versus Bupivacaine-Dexamethasone for Postoperative Analgesia in Laparoscopic Cholecystectomy
Name
88-11/2018
Description
The aim of the present study was to compare the effectiveness of transmuscular Quadratus Lumborum block using Bupivacaine versus Bupivacaine- Dexamethasone in providing analgesia in patients undergoing laparoscopic cholecystectomy.
Because postoperative pain after laparoscopic surgery is complex, specialists suggest that effective analgesic treatment should be a multimodal support. Quadratus lumborum block (QLB) is a new abdominal truncal block for controlling somatic pain in both the upper and lower abdomen. Dexamethasone, through its anti-inflammatory and blocking effects on neural discharge, and nociceptor C fibers transmission could be used as a local anesthetic adjuvant.

Treatment
TQL block with saline
drug: saline 21 ml 0.9% normal saline administered on each side as bilateral TQL blocks Drug: fentanyl With induction of general anaesthesia, fentanyl (1 microgram.kg) will be given. Intraoperatively, fentanyl boluses (0.5 microgram.kg) will be given in case of increase in intraoperative mean arterial blood pressure or heart rate of more than 20% of baseline for longer than 5 minutes.
Drug: Paracetamol Paracetamol infusion (15 mg.kg) will be given by intravenous infusion after induction of general anesthesia. Postoperatively, 1 g of paracetamol will be given by intravenous infusion to all cases every 8 hours.
Drug: Ketorolac analgesia In PACU Ketorolac 30 mg ampoule will be given by intravenous infusion to all cases Drug: Nalbuphine Nalbuphine boluses 0.1 mg. /kg will be given as rescue analgesia if VAS is more than3.
