    ObjectiveTo evaluate the independent risk factors for failure of continuous veno-venous hemodialysis (CVVHD) in the treatment of acute kidney injury (AKI) following cardiac surgery.MethodsAdult patients without any prior pre-operative history of chronic renal disease suffering AKI following cardiac surgery and undergoing CVVHD at our center from January 2005 to December 2012 were recruited and divided into either a success group or a failure group. All pre-, intra- and post-operative data were collected and retrospectively analyzed.ResultsNinety-three adult patients were enrolled. Among them, sixty-three patients survived with a failure rate of 32.2% and a mortality rate of 19.4%. Through univariate analysis and multivariate Logistic regression, independent risk factors for failure of CVVHD in the treatment of post-operative AKI included pre-operative LVEF (OR = 0.61, 95%CI 0.42-0.85) and duration of oliguria until dialysis (OR = 2.76, 95%CI 1.51-5.83).ConclusionPre-operative impaired left ventricular function is an important risk factor for failure of CVVHD in the treatment of AKI after cardiac surgery. The sooner the implementation of CVVHD, the better prognosis.
