Key result
Glucocorticoid administration maintained left ventricular systolic function in neonatal piglets after cardiopulmonary bypass and deep hypothermic circulatory arrest compared to saline.
Why the study?
Does methylprednisolone improve ventricular recovery in neonatal piglets undergoing cardiopulmonary bypass and deep hypothermic circulatory arrest?
Does methylprednisolone improve ventricular recovery in neonatal piglets undergoing cardiopulmonary bypass and deep hypothermic circulatory arrest?
Glucocorticoid administration, particularly when initiated before surgery, improves recovery of left ventricular systolic function and oxygen delivery in a neonatal piglet model of cardiopulmonary bypass and deep hypothermic circulatory arrest.

No change to neonatal CPB practice; extends glucocorticoid LV preservation to DHCA model but leaves open human translation.

Duffy et al. (2004) studied Cardiopulmonary bypass and circulatory arrest. Methylprednisolone vs. Saline was evaluated on Left ventricle positive change in pressure in time (+dP/dt). Glucocorticoid administration maintained left ventricular systolic function in neonatal piglets after cardiopulmonary bypass and deep hypothermic circulatory arrest compared to saline.
