The primary outcome of this study was the amount of opioid consumption in the first 24h after surgery; postoperative pain scores and the time of first opioid demand were the secondary outcomes. Morphine consumption was measured at 3, 6, 9, 12, 18, and 24h, and static and dynamic pain scores were measured at 1, 3, 6, 9, 12, 18, and 24h postoperatively.A five-stage verbal descriptive scale (0 = absent, 1 = mild nausea, 2 = moderate nausea, 3 = vomiting once, and 4 = vomiting more than once) was used to score the intensity of nausea and vomiting. Ondansetron (4mg IV) was administered to patients with a score of ≥ 3. Reports of nausea and vomiting as well as technical and drug-related issues (respiratory depression, local anesthetic toxicity, hematoma, and organ damage) were recorded.
