Baby Heart Surgery Death Related Risk Factor Analysis

Objective:To explore the cardiac surgery death related risk factors in infants, so providing the theoretical basis for improving of cardiac surgery survival rate in infants. Method:Retrospective analysis of108cases of patients undergoing cardiac surgery of infant clinical data in xinjiang medical university first affiliated hospital in2009～2012, there are99patients in living group, and9patients in death group. Survey content mainly includes:.(1) preoperative factors:gender, age, preoperative diagnosis, left ventricular end-diastolic diameter and left ventricular contraction at the end of the inner diameter.(2) intraoperative factors:the aorta blocking time, extracorporeal circulation time.(3) postoperative factors:postoperative thoracic fluid volume, hospitalization days, breathing machine auxiliary time, ICU length of hospital stay, etc. All the data using SPSS11.0for Windows statistical software for statistical analysis. First, using single factor analysis and screening out two groups which have significant differences in variables, then using multiple factors analysis to find out influence risk factors of cardiac surgery death in infants. Results:(1) the Fisher’s exact probability method comparative analysis found that different kinds of congenital heart disease, postoperative death situation is different, the postoperative complications is different. Four index variable is statistically significant difference (P<0.05)(2) Single factor analysis showed that the age, weight, extracorporeal circulation time, aortic block time, breathing machine auxiliary time, Aristotle score and seven variables have significant differences in survival group and death group (P<0.05). Gender, preoperative hospitalization days, postoperative thoracic fluid volume, ICU length of hospital stay, creatinine, total bilirubin, albumin, globulin, white blood cells, lymphocytes, hemoglobin, nmda aminotransferase, alanine aminotransferase, alkaline phosphatase, left ventricular end-diastolic diameter, left ventricular contraction at the end of the inner diameter have no significantly difference, P>0.05.(3) the multi-factor analysis showed that age, weight, extracorporeal circulation time, aortic block time and five variables are risk factors for cardiac surgery in infants death (P<0.05). Conclusions:(1) Age, weight, extracorporeal circulation time and aorta blocking time are important indexes of cardiac surgery in infants death.
