Brief summary:
Randomized controlled trial of the use of glucocorticoids to improve the clinical course of neonates post-cardiopulmonary bypass (CPB).

Detailed description:
This study proposes a randomized controlled trial of the use of glucocorticoids to improve the clinical course of neonates post-cardiopulmonary bypass (CPB). The study will focus on neonates for a few reasons. Although their post-CPB clinical course is typically more severe and intensive care unit (ICU) care more prolonged than older children, their modes of morbidity are also well characterized. Further, the high level of severity itself provides a substrate for identifying the positive effects of a particular therapy. Finally, a therapy identified as beneficial has the greatest potential for benefit in this vulnerable population. The well characterized scenario of low cardiac output syndrome (LCOS) will be used as the primary endpoint, while a variety of secondary endpoints will be related to the biochemical anti-inflammatory effects of therapy, ICU care and late neurological outcome.

Arms:
arm 1: Neonates with congenital heart disease requiring surgery utilizing a cardiopulmonary bypass (CPB) machine in the first month of life that receive ONE dose intravenous methylprednisolone (IVMP) prior to heart surgery. arm 2: Neonates with congenital heart disease requiring surgery utilizing a cardiopulmonary bypass (CPB) machine in the first month of life that receive TWO doses intravenous methylprednisolone (IVMP) prior to heart surgery.Compare the effects and preoperative and intraoperative IVMP to intraoperative IVMP alone on the inflammatory response to CPB cardiopulmonary bypass. The hypothesis is that neonates treated with preoperative IVMP as well as the standard intraoperative IVMP will have decreased production of pro-inflammatory cytokines.

Interventions: intervention 1: methylprednisolone (IVMP) intervention 2: methylprednisolone (two doses IVMP)
Intervention descriptions: intervention 1: Neonates with congenital heart disease requiring surgery utilizing a cardiopulmonary bypass (CPB)machine in the first month of life that receive ONE doses intravenous methylprednisolone (IVMP) prior to heart surgery.Compare the effects and preoperative and intraoperative IVMP (2 dose steroid)to intraoperative IVMP alone (single dose steroid) on the inflammatory response to CPB cardiopulmonary bypass. intervention 2: Neonates with congenital heart disease requiring surgery utilizing a cardiopulmonary bypass (CPB)machine in the first month of life that receive TWO doses intravenous methylprednisolone (IVMP) prior to heart surgery.Compare the effects and preoperative and intraoperative IVMP to intraoperative IVMP alone on the inflammatory response to CPB cardiopulmonary bypass.
