초록
Although α2-adrenoceptor agonists are widely used as postoperative sedatives in adults, the postoperative effects in pediatric patientswith secondary pulmonary arterial hypertension (PAH) due to congenital heart disease are not well known. We experienced a case of successful ventilator weaning with continuous intravenous administration of dexmedetomidine (DEX) after surgical correction in a 46-month-old child with congenital ventricular septal defect (VSD) with severe PAH. She underwent VSD closure on cardiopulmonarybypass (CPB). After successful weaning from the CPB, hemodynamics and oxygenation were stabilized on DEX and nitroglycerin in the intensive care unit. The patient was successfully weaned from the ventilator 46 hours after surgery. The transthoracic echocardiogramtwo weeks after surgery showed a closed VSD with no residual shunt and trivial tricuspid regurgitation (Vmax = 2.5 m/sec) without PAH.
