Abstract:
Objective To evaluate the risk factors for the postoperative acute renal failure requiring dialysis (ARF-D)after heart valve surgery. Methods Adult 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.Results The 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 class Ⅳ,and low cardiac output syndrome. ARF-D group had a longer hospital stay and ICU stay than that of the control group ( P ＜0.001 ). Conclusion Conclusion ARF-D had a higher mortality rate and longer hospital stay following heart valve surgery.Age, previous cardiac surgery, preoperative serum creatinine, NYHA class Ⅳ, and low cardiac output syndrome were the independent risk factors of ARF-D after heart valve surgery.
