The prognostic value of cerebral oxygen saturation, lactate and mixed venous oxygen levels in predicting the major adverse events during pediatric cardiac surgery

Objective: Major adverse events (MAE) that may occur after pediatric cardiac surgery increase the risk for mortality and morbidity. In this context, the objective of this study is to assess the prognostic value of perioperative cerebral oxygen saturation levels measured by near-infrared spectroscopy (NIRS-ScO2) and lactate and mixed venous blood oxygen saturation (MVO) levels in predicting the development of MAE after the surgery.
