Abstract
Objective Summarize experience on extracorporeal membrane oxyenation (ECMO) for cardiac surgery,and characterize the association between mortality and RIFLE (risk of renal failure,injury to the kidney,failure of kidney function,loss of kidney function and end-stage renal disease) classification.Methods From October 2004 to November 2006,40 patients undergoing ECMO after cardiac surgery,the duration of ventilation support,ICU stay and outcomes were recorded.Results Mean duration of ECMO was (56.8±44.1)hours.Thirty-two patients (80%) were successfully weaned from ECMO,twenty-two patients(55%) were discharged from hospital.The overall mortality rate was 45%.A significant increase (χ2 for trend,P＜0.01) in mortality was observed based on RIFLE classification.By applying the area under the receiver operating characteristic curve(AUROC),the RIFLE classification is a tool of good discriminative power [AUROC 0.904,(95% CI 0.798-1.010),P＜0.01].Conclusion The RIFLE classification is a simple and valuable method with good prognostic capability to evaluate acute renal failure after cardiac surgery with ECMO.
