Evaluation of Ultrasound- Guided Quadratus Lumborum Block for Postoperative Analgesia after Hip Surgery

Abstract

ip fractures rate increased those days and postoperative pain control. The goal of postoperative pain management is provision of comfort, early mobilization and improved respiratory function without causing inadequate sedation and respiratory compromise, which can be achieved through using multimodal analgesic therapy, preference for regional techniques, avoidance of sedatives, non-invasive ventilation with supplemental oxygen and early mobilization. The main advantage of quadratus lumborum block (QLB) compared to Spinal anaesthesia is the extension of local anesthetic agent beyond the transverses abdominis plane to the thoracic paravertebral space. The wider spread of the local anesthetic agents may produce extensive analgesia and prolonged action of the injected local anesthetic solution. The aim of this study was to assess the analgesic efficacy of ultrasound-guided trans-muscular QLB compared with spinal anaesthesia during Hip surgery and in the early postoperative period regarding pain relief, provision of comfort, and improved respiratory functions. After approval of anesthesiology department scientific and ethical committees in Ain Shams University Hospitals, patients were included in the study, and were divided into two groups (n=32; each); group QLB and group spinal.
