Acute Kidney Injury in Children After Cardiopulmonary Bypass: Risk Factors and Outcome.

ABSTRACT

Objective: To determine the incidence, risk factors and outcomes of acute kidney injury in children undergoing cardiac surgery for congenital heart disease. Methods: We enrolled 208 patients undergoing cardiac surgery for congenital heart disease during January 2012 to March 2013. Acute kidney injury was defined as per Acute Kidney Injury Network criteria. Results: Twenty patients had Acute kidney injury; 14 were infants. Age <1 yr, cardiopulmonary bypass time, prolonged ventilator requirement, pump failure, sepsis and hematological complications were identified as independent risk factors for any degree for acute kidney injury. All patients with acute kidney injury recovered the kidney function at the time of discharge. Conclusions: Acute kidney injury is common in children after cardiac surgery, especially in infants.
