It included cancer patients scheduled for major lower abdominal cancer surgery in the period from 2019 to 2020. They were divided into two groups: Group Ι received pre-emptive ultrasound-guided Quadratus Lumborum Block (QLB) with 25 mL of 0.25% bupivacaine on each side of the abdominal wall before induction of General Anesthesia (GA), and Group II received pre-emptive lumbar epidural block with 15 mL of 0.25% bupivacaine before induction of GA. VAS score, and time of the first analgesic request and postoperative total analgesic consumption were evaluated. <b>Results:</b> Sixty patients were included in our study. VAS score at rest was comparable between both studied groups in the first 6 h. At 8 and 10 h, Group II had a significantly higher VAS score at rest (P < 0.001 and 0.026 respectively). Meanwhile, at 12 h, patients in Group I had a significantly higher VAS score (P = 0.026). Mean time of the first request for rescue analgesia was significantly prolonged in Group I (13.27 ± 2.38 hrs.) compared to Group II (10.20 ± 1.42 hrs.) (P < 0.001) respectively, mean total morphine consumption, over the first 24 hours postoperatively, was significantly lower in Group I (5.17 ± 1.32 mg) than in Group II (7.33 ± 1.45 mg) (P < 0.001). A larger number of patients in Group II had nausea at different time points postoperatively than in Group I (P < 0.001), but no significant difference was observed between both studied groups regarding the incidence of vomiting. <b>Limitation:</b> Small sample size and shorter period for postoperative follow-up. <b>Conclusions:</b> Management of postoperative pain following major lower abdominal cancer surgery with US-guided QLB was associated with the reduction in the total analgesic consumption and delayed the first request of analgesia as compared to lumbar epidural block technique.展开更多
