Ultrasound Guided Quadratus Lumborum Block In Cirrhotic Patients Undergoing Major Abdominal Surgery (Randomized Control Trial)

Abstract

Objectives: to assess the effect of ultrasound-guided bilateral continuous anterior QLB on alleviating pain and fentanyl consumption in cirrhotic patients who undergoing major abdominal surgery. Methods: 60 cirrhotic patients undergoing major abdominal surgery were involved in this double blinded randomized control study. In group B bilateral anterior QLB with (0.4ml/kg) bupivacaine 0.25% in each space between QL and psoas major muscle then continuous infusion of bupivacaine 0.25% at dose 10ml/hr. In group S bilateral anterior QLB with equal volume of 0.9 saline in the same plane. Hemodynamics, intra and postoperative analgesic consumption, VAS score, incidence of nausea and vomiting, respiratory complications were recorded. Results: The mean fentanyl consumption intra and 12 hours postoperative in group B and group C were (337.93± 135.39 and 312±170.36 VS. 518.33 ±121.40 and 582.00 ±141.16 microgram p
