INCIDENCE AND DIFFERENT RISK FACTORS OF CARDIAC SURGERY ASSOCIATED ACUTE KIDNEY INJURY

Objective: To identify the incidence of cardiac surgery associated acute kidney injury and its association with different risk factors. Study Design: Descriptive cross sectional study. Place and Duration of Study: Adult cardiac surgery department, AFIC/NIHD, from Jan to Jun 2019. Methodology: Three hundred forty patients undergoing cardiac surgery were evaluated for Cardiac Surgery associated acute kidney injury according to acute kidney injury network criteria over a period of 6 months. The chi-square test was used find the relationship of different factor for cardiac surgery associated acute kidney injury. Results: Total of 430 patients were included. 345 (80.2%) were male and mean age of 55 ± 11.6 years and mean pre operative creatinine clearance was 80.7 ml/hr. Coronary artery bypass grafting was the most common procedure performed. Intra aortic balloon pump, Cardio-pulmonary bypass time, AXc time, ionotropes, transfusion of RCC and FFPs were found to be highly significant risk factors of acute kidney injury. Conclusion: Cardiac surgery associated acute kidney injury is very common complication; some of the modifiablefactors should be identified and controlled to reduce acute kidney injury.
