Incidence and peri-operative risk factors for development of acute kidney injury in patients after cardiac surgery: A prospective observational study.

Background: Patients admitted to intensive care unit (ICU) after cardiac surgery develop acute kidney injury (AKI) immediately post-operation. We hypothesized that AKI occurs mainly due to perioperative risk factors and may affect outcome.

Aim: To assess peri-operative risk factors for AKI post cardiac surgery and its relationship with clinical outcome.
