Early Postoperative Fluid Overload Precedes Acute Kidney Injury and Is Associated With Higher Morbidity in Pediatric Cardiac Surgery Patients

Abstract

Early postoperative fluid overload is independently associated with worse outcomes in pediatric cardiac surgery patients who are 2 weeks to 18 years old. Patients with fluid overload have higher rates of postcardiopulmonary bypass acute kidney injury, and the occurrence of fluid overload precedes acute kidney injury. However, acute kidney injury is not consistently associated with fluid overload.
