Cardiac Surgery Acute Kidney Injury: Controversy in Renal Support
Acute kidney injury (AKI) is a common complication after cardiac surgery and is associated with increased patient morbidity and mortality including hospital readmissions. Cardiac surgery-associated acute kidney injury (CS-AKI) manifests often in the post-operative setting and is frequently related to patient co-morbidities as well as intraoperative factors that are not easily modifiable. Detecting AKI usually relies on decreases in urine output and acute increases in serum creatinine, and management in the post-operative period focuses on reducing ongoing renal insult, prudent management of perioperative hemodynamics and patient volume status. When acute renal failure occurs, renal replacement therapies (RRT) are commonly required for management of these critically ill patients, although debate persists on the optimal timing to initiate RRT when acute renal injury occurs after cardiac surgery.
