Abstract

Background: Acute renal failure (ARF) is one of the most serious complications of cardiac surgery. Its incidence varies between 1 and 30%. ARF requiring renal replacement therapy (ARF-RT) develops in 1% to 5% of patients and is associated with a very high mortality. Objective: This study evaluated the risk factors of ARF in a surgical population with or without preoperative renal dysfunction. Method: This was a cross-sectional study reviewing the medical records of 1,000 patients undergoing cardiac surgery. Data were collected from October 1, 2020 to September 30, 2021, using the data collection on the incidence of acute renal failure in patients undergoing cardiac surgery. The relationship between factors was analyzed using the chi-square test and stepwise binary logistic regression analysis. Result: From the sample of 1,000 cardiac surgical patients, it was found that the risk factors associated with acute renal failure after cardiac surgery, by the analysis of multivariate forward stepwise binary logistic regression, were age group (adjusted OR 7.40, 95%CI: 2.99, 18.29, p <. 001), male gender (adjusted OR 1.656, 95%CI: 1.18, 2.332, p = .004), left ventricular dysfunction (adjusted OR 1.446, 95%CI: 1.1,1.89, p =. 007), history of chronic kidney disease (adjusted OR 1.446, 95%CI: 1.1,1.89, p = .007), pre-operative IABP (adjusted OR 3.768, 95%CI: 2.43, 5.85, p < .001), higher pre-operative creatinine level (mg%) (adjusted OR 2.173, 95%CI: 1.39, 3.4, p = .001) with accuracy rate of 80.2 and area of ROC of 0.701±0.021 (95%CI: 0.661, 0.742, p-value < .001). Conclusion: The male patients with left ventricular dysfunction and underling chronic kidney disease who underwent open heart surgery should have prophylactic guideline in order to prevent acute renal failure after cardiac surgery in patients who had preoperative IABP had significant risk for developing acute renal failure that required treatment guidelines for reducing morbidity and mortality.
