BackgroundOpen living donor hepatectomy (OLDH) is a highly painful procedure. Advanced strategies for enhancing perioperative analgesia and accelerating recovery are needed for patients undergoing OLDH. This study evaluated the effects of intravenous infusion of dexmedetomidine (DEX) during OLDH on postoperative analgesia and recovery.MethodsThis prospective, randomised, double-blinded, and placebo-controlled study included 34 patients randomised to a control group (group C) and a DEX group (group D). Utilisation of intravenous patient-controlled analgesia (IV-PCA) pump, pain intensity, and postoperative recovery variables were recorded. Moreover, intraoperative anaesthetic consumption, hemodynamic parameters, and fluid status were also recorded.ResultsDuring the first 24 hours after surgery, patients in group D had a lower pain intensity. The cumulative numbers of IV-PCA pump presses and fentanyl consumption within 24 and 48 hours postoperatively in group C were significantly higher than in group D. The time to first IV-PCA attempt was prolonged in group D. In addition, faster flatus passage was observed in group D. Intraoperatively, fewer anaesthetic agents were required in group D. Less fluctuation in hemodynamics and reduced bleeding were also found in group D.ConclusionsThe present study revealed that the addition of intravenous infusion of DEX during OLDH provided several benefits in relieving postoperative pain and promoting recovery. Therefore, we concluded that intraoperative DEX infusion may play an important role in enhancing the recovery of patients undergoing OLDH.© 2021 John Wiley & Sons Ltd.
