Background: The mortality due to Coronary Artery Bypass Graft (CABG) in patients with chronic renal failure is more common than normal population. This study evalu-ates the impacts of prophylactic dialysis on decreasing mortality and morbidity of non- dialysis-dependent patients with renal failure after CABG surgery. Methods: In this study, fifty non-dialysis-dependent patients who were suffering from renal failure and needed to CABG, were selected by convenience sampling method. Se-quentially, they were allocated to prophylactic dialysis (n=20) and no prophylactic dialysis (n=30) groups, using a randomized block design. Exclusion criteria were under 18 year old patients and doing CABG for second time. Mortality rate and some complications such as acute renal failure, brain accident and atrial arrhythmias were compared between two groups after CABG. All cardiac surgeries were performed in a single centre and through a median sternotomy. P value less than 0.05 was considered as significant. Results: The mean age of patients was (65.3±9.9). The patients included %16 (n.8) of women and %84 (n.42) of men. There were 20 patients in intervention and 30 patients in control groups. Baseline characteristics were similar in two groups. Comparison be-tween intervention and control groups after surgery did not show any difference in mortality (P=0.14), acute renal failure (P=0.4), cerebrovascular accidents (P=1) and atrial arrhythmias (P=0.3), need to second surgery due to bleeding (P=1), need to dialysis (P=0.14), need to rehospitalization (P=1), duration of ventilator use (P=0.4), duration of need to hospitalization (P=0.11), duration of a patients stay in the Intensive Care Unit (P=0.4) and deep sternal infection (P=0.7) rates. Conclusion: According the results of this study, prophylactic dialysis, before conduct-ing CABG, does not have any significant effect on mortality and other complications. The only exception is lung complications in non-dialysis-dependent patients with renal failure.
