Effect of Nifedipine in Acute Episode of Postoperative Pulmonary Hypertension and Right Heart Failure
|
|
|
|
|
Abstract
|
|
|
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 vasoactive drugs. Nifedipine, 0.3mg/kg every 4 hours, effectively treated her pulmonary artery hypertension and allowed for a smooth postoperative course
and
positive cutcome. The drug lowered systemic diastolic pressure, but not systolic pressure.
