Vasoactive–inotropic score as a predictor of morbidity and mortality in infants after cardiopulmonary bypass*

The amount of cardiovascular support in the first 48 hrs after congenital heart surgery with cardiopulmonary bypass predicts eventual morbidity and mortality in young infants. The degree of support is best characterized by a maximum vasoactive-inotropic score obtained during this period. The usefulness of vasoactive-inotropic score as an independent predictor of clinical outcome in infants after cardiac surgery may have important implications for future cardiothoracic intensive care unit research.
