ObjectiveThis study investigated the effects of aortic root infusion of sufentanil on myocardial ischemia/reperfusion injury in patients undergoing elective mitral valve replacement (MVR) with cardiopulmonary bypass (CPB).DesignA prospective, randomized, clinical study.SettingA university-affiliated teaching hospital.ParticipantsFifty-three adult patients undergoing elective MVR with CPB.InterventionsBolus infusions of sufentanil (0.2 μg/kg, n = 24) or normal saline (n = 29) were administered through the aortic root cardioplegia perfusion catheter 5 minutes before aortic unclamping.Measurements And Main ResultsPlasma concentrations of CK-MB and cTnI and variables including heart rate, mean arterial pressure, central venous pressure, cardiac output, stroke volume, duration of mechanical ventilation, length of ICU stay, length of hospital stay, and 24-hour postoperative inotropic scores were recorded. Plasma concentrations of CK-MB and cTnI were significantly lower 4 and 8 hours after aortic unclamping in the sufentanil postconditioning group compared to control (p<0.05). Inotropic drug use, duration of mechanical ventilation, and length of ICU and hospital stays were reduced significantly in the sufentanil postconditioning group compared to control (p< 0.05).ConclusionsThe present study demonstrated that sufentanil can attenuate myocardial ischemia-reperfusion injury in patients undergoing elective MVR with CPB.Copyright © 2014 Elsevier Inc.
