The Vasoactive-Inotropic Score at 48 hours is a good surrogate marker
for adverse postoperative events in pediatric patients undergoing
cardiac surgery with cardiopulmonary bypass and is limited by its
ability to delineate the underlying cause for an unfavourable clinical
course. Thus, other predictors such as the Technical Performance Score
are likely to highlight the underlying cause and can be used to improve
outcomes. However, patients with a high postoperative VIS score at 48
hours may benefit from closer longer-term follow for outcomes such as
late survival, functional class, and need for reoperation.
