Effect of Nifedipine in Acute Episode of Postoperative Pulmonary Hypertension and Right Heart Failure

심장 수술후에 발생한 급성 폐동맥 고혈압및 우심부전증 환자에서 nifedipine의 효과

We report the successful use of Nifedipine in the treatment of acute pulmonary hypertension in an young child after a cardiac operation. This patient had undergone patch closure of large ventricular septal defect. She had signs of severe pulmonary artery hypertension unresponsive to hyperventilation, oxygenation, sedation, and a myriad of vas-oactive drugs. Nifedipine, 0.3mg /kg every 4 hours, effectively treated her pulmonary artery hypertension and allowed for a smooth postoperative course and positive outcome. The drug lowered systemic diastolic pressure, but not systolic pressure.
