OBJECTIVE: To determine the efficacy and adverse effect profile of clevidipine when used for perioperative blood pressure (BP) control during surgery for congenital heart disease (CHD). METHODS: We retrospectively reviewed our experience with the perioperative use of clevidipine in pediatric-aged patients undergoing surgery for CHD. RESULTS: The study cohort included 14 patients ranging from 11 months to 15 years (7.4 ± 4.6 years) and weighing from 5 to 41 kg (21.8 ± 11.1 kg). Clevidipine was administered as a continuous infusion for control of either postoperative BP or intraoperative mean arterial pressure (MAP) during cooling and cardiopulmonary bypass (CPB). It was administered as a bolus for BP control during emergence from anesthesia following cardiac surgery. The continuous infusion was started at 1 mcg/kg/min and increased in increments of 0.5 to 1 mcg/kg/min as needed. For postoperative BP control, dosing requirements varied from 1 to 7 mcg/kg/min (mean = 2.0 ± 1.2 mcg/kg/min). The target BP was achieved within 5 minutes in all patients. Two patients were treated with intravenous or oral propranolol for an increase in heart rate (HR) while receiving clevidipine. Despite doses up to 10 mcg/kg/min, effective control of MAP could not be achieved during CPB and cooling (core body temperature 28°C to 32°C). Bolus doses of clevidipine (10 to 15 mcg/kg) controlled BP during emergence from anesthesia with a decrease of the MAP from 97 ± 6 mm Hg to 71 ± 5 mm Hg (p<0.01). CONCLUSIONS: Clevidipine is effective for perioperative BP control in infants and children with CHD; however, it does not appear effective in controlling MAP during cooling and CPB.
