Objective To analyze the risk factors for delayed sternal closure (DSC) in the operation for the neonates with congenital heart defects. Methods We retrospectively analyzed the case notes of the 203 neonates with congenital heart defect in our hospital between January 2010 and June 2014. There were 152 males and 51 females at age of 0-28 (17.68±8.62) days. The relative factors were analyzed by univariate and multivariate logistic regression. Results These factors significantly correlated with DSC in univariate analysis:age at operation, premature, low weight (weight≤2.5 kg) at operation/weight at operation, RACHS-1, mechanical ventilation before operation, continuous use of intravenous cardiovascular drugs before operation, CPB time, aortic clamping time, total circulatory arrest with profound hypothermia. The results of logistic regression analysis showed that weight at operation/low weight, pre-operative mechanical ventilation, total circulatory arrest with profound hypothermia were independent risk factors for DSC. Conclusion Weight at operation/low weight, pre-operative mechanical ventilation, and total circulatory arrest with profound hypothermia are the independent risk factors for DSC in the operation for the neonates with congenital heart defects.
