End-stage renal disease (ESRD) is an important risk factor for coronary and valvular cardiac disease leading to cardiac surgery. Both volume overload and coagulopathy in the immediate post-operative period after cardiac surgery are important predictors of clinical course and mortality. Previous studies have demonstrated that presence of ESRD is an independent risk factor for post-operative respiratory failure and mortality in patients undergoing cardiac surgery, partially mediated through volume overload and prolonged mechanical ventilation, as well as coagulopathy attributed to platelet dysfunction and uremia.~Prolonged mechanical ventilation after cardiac surgery has been shown to be associated with higher morbidity and mortality. Fluid overload is a predictor of length of mechanical ventilation and intensive care unit (ICU) stay. Therefore early restoration of volume and electrolyte homeostasis and clearance of uremic toxins should be one of the principal goals in the immediate post operative period in patients with ESRD. However, to the best of our knowledge, the effect of timing of post-operative renal replacement therapy, specifically hemodialysis, on clinical outcomes has not been studied in ESRD patients undergoing cardiac surgery.~Accordingly, we are planning to conduct this study to evaluate the effect of early hemodialysis treatment after cardiac surgery, on clinical outcomes related to volume overload and coagulopathy (i.e. duration of mechanical ventilation, transfusion requirements, and length of ICU stay) in patients with ESRD
