ObjectiveTo evaluate risk factors for postoperative acute renal failure requiring dialysis(ARF-D)after heart valve surgery.MethodsAdult patients(age≤18 years)underwent valve surgery with preoperative serum creatinine <300 μmol/L were included between January 2005 and December 2008.Fifty patients developed ARF-D within 30 days postoperatively(ARF-D group).While random 220 patients had the same operation without ARF-D served as the control group.Univariate analysis and multivariable logistic regression were used to identify risk factors of ARF-D after valve surgery.ResultsThe incidence of ARF-D was 1.78%,and the early mortality rate was 65.5%.Multivariate analysis identified the following independent risk factors of ARF-D:age,previous cardiac surgery,preoperative serum creatinine,NYHA classⅣ,and low cardiac output syndrome.ARF-D group had a longer hospital stay and ICU stay than those the control group had(P <0.001).ConclusionARF-D had a higher mortality rate and longer hospital stay following heart valve surgery.Age,previous cardiac surgery,preoperative serum creatinine,NYHA classⅣ,and low cardiac output syndrome were the independent risk factors of ARF-D after heart valve surgery.16 refs,4 tabs.
