Abstract

Background: Various techniques, including quadratus lumborum (QL) block, transversus abdominis plane (TAP) block, caudal block, ilioinguinal block, and wound infiltration, are all methods for adequate postoperative pain management. Effective pain relief can accelerate patient recovery, alleviate psychological distress, and improve parental satisfaction.
Aim: This study aimed to evaluate the analgesic effect of ultrasound-guided quadratus lumborum Block (QLB) in patients having lower abdominal surgery at Suez Canal university hospitals.
Patients and Methods: This prospective study was conducted on patients undergoing lower abdominal surgeries at Suez Canal University Hospital. Thirty five patients received ultrasound- guided quadratus lumborum block with 20 ml of bupivacaine 0.25%. Each participant was subjected to clinical evaluation including medical history, physical examination and essential laboratory investigations.
Results: Patients had mean age of 49.17 ± 8.94 years old, gender showed almost equal distribution and mean weight was 84.11 ± 7.57 kg. Patients had mean total morphine consumption of (13.1 ± 1.3 mg), mean time of the 1st request of analgesia (7 ± 2.3 hours). There was no significant difference between the serial vas postoperative at rest at 60 min 12, 24 hours postoperative. Only 5.8% of patients had postoperative side effects (post operative nausea and vomiting).
Conclusion: This study suggests QL block use for the patients undergoing lower abdominal surgery, as this method was an effective postoperative analgesic technique.
