5. Study Description
Brief Summary
The aim of this study is to determine the safety and efficiency of Remodulin®(Treprostinil Injection)to reduce the pulmonary arterial pressure and prevent pulmonary hypertension (PH) after Fontan operation with univentricular physiology.
Detailed Description
PH is a significant contributor to the postoperative morbidity and mortality of congenital heart disease, especially after Fontan operation with univentricular physiology. Mild increase of pulmonary vascular resistance may lead to failure of Fontan circulation. Remodulin® has been approved for the treatment of adults with PH, but little is known about the effects in children with PH after Fontan operation. The study aim is to determine the safety and efficiency of Remodulin® to reduce the pulmonary arterial pressure and prevent PH in children after Fontan operation. Meanwhile pharmacokinetics of the drug were checked with or without the peritoneal dialysis.

Intervention Type
Drug
Intervention Name(s)
Remodulin
Other Intervention Name(s)
Treprostinil Injection
Intervention Description
After Fontan operation, the mean pulmonary arterial pressure (mPAP)evaluated by CVP or transpulmonary pressure gradient(TPG) evaluated by Echo will be measured firstly, if the data met the criteria, and the patients were enrolled in the experimental group, the patients would be administrated intravenously of Remodulin® with the beginning of 5ng/kg/min, with the rate of 10ng/kg/min every 30 minutes up to 80ng/kg/min.
Intervention Type
Drug
Intervention Name(s)
distilled water
Other Intervention Name(s)
placebo
Intervention Description
After Fontan operation, the mPAP (evaluated by CVP) or TPG (evaluated by Echo) will be measured firstly, if the data met the criteria, and the patients were enrolled in placebo group, then the patients would be administrated intravenously of distilled water with the beginning of 0.15ml/hr, with the rate of 0.3ml/hr every 30 minutes up to 2.45ml/hr.
