| Background Hepatectomy elaborates significant post-operative pain. Opioids represent cornerstone for post-operative analgesia in such cases. This study examined the therapeutic effect and outcome of adding low dose ketorolac tromethamine infusion to PO intravenous patient controlled fentanyl analgesia IV-PCA. Patients and methods Sixty right lobe donors were randomized into either fentanyl or ketorolac groups (30 patients each). Patients in both groups received fentanyl (2 μg/ml) solution in normal saline as IV-PCA with background infusion in a rate adjusted to deliver 0.25 μg kg h and boluses of 10 ml with a lock-out time of 20 min. They received 15 mg ketorolac IV bolus in ketorolac group and similar placebo injection in the control. Patients in both groups received a continuous intravenous infusion of 240 ml normal saline solution that is either free in the FENT group or containing 60 mg ketorolac in ketorolac group, adjusted to a rate of 0.2 ml kg h. Visual analogue score (VAS) and hemodynamic profile were recorded at 1, 6, 12, 24, 36 and 48 h while laboratory results were recorded after 48 h and 7 days post-operatively. Results VAS was significantly lower in ketorolac group compared to fentanyl group from 6 to 36 h post-operatively while sedation score was significantly higher in fentanyl group compared to fentanyl–ketorolac group between 12 and 36 h post-operatively. Fentanyl consumption was significantly lower in ketorolac group at 24 (318.7 ± 66 vs 468.3 ± 79) and 48 (211.5 ± 59 vs 369.1 ± 68) h. Hemodynamic data and laboratory parameters were comparable in both groups. Nausea had a significantly higher incidence in FENT compared to KETR groups while other complications (vomiting and blood loss) were homogenous in both groups. Conclusion Adding ketorolac to IV PCA fentanyl improved the analgesic state and reduced the dose of fentanyl used without adding any side effects or risks to donors subjected to right lobe hepatectomy. | ||||
