[Risk factors of death in newborns with congenital diaphragmatic hernia].
Objective:To investigate risk factors of death in newborns with congenital diaphragmatic hernia (CDH). Method:A total of 126 newborns with CDH from June 2012 to September 2018 were enrolled. Concomitant malformations were recorded by descriptive analysis. Newborns received surgical treatment (n=120) for CDH were divided into survival group and fatal group. The risk factors of death were analyzed by univariate and multivariate logistic regression and the ROC curve with generated with relevant variables. Result:There were 55 CDH newborns with concomitant malformations (43.7%), including 20 cases (15.9%) with multi-malformation. Logistic regression analysis showed that premature rupture of membranes (PROM), postoperative atelectasis, long duration of postoperative mechanical ventilation, postoperative high oxygenation index (OI) were related to death (all P<0.05), and the delayed surgery was a protective factor (P<0.05). In ROC analysis of postoperative OI in predicting death, the area under the curve (AUC) was 0.841, with the cutoff value of 5.74, the sensibility and specificity of OI was 81.0% and 75.0%, respectively(P<0.01). Conclusions:Newborns with CDH have a high rate of malformations. The risk factors of death were PROM, postoperative atelectasis, postoperative long duration of mechanical ventilation and higher postoperative OI, and delayed surgery may reduce mortality.PMID: 31102362
