Influence of Intraoperative Fluid Balance on the Incidence of Adverse Events in Pediatric Cardiac Surgery

The intraoperative fluid balance during pediatric cardiac surgery is a very sensitive parameter given the low circulating volume and the complexity of anesthetic management but might be deleterious if inadequately managed. The hypothesis is that a highly positive intraoperative fluid balance increases the incidence of adverse events in the short and long term. A retrospective observational study including all consecutive children admitted for cardiac surgery with cardiopulmonary bypass (CPB) from 2008 to 2018 in a tertiary children's hospital will be performed. A multivariate analysis will be carried out to study the effect of the fluid balance on the incidence of adverse events.
