【摘要】 目的探讨极早产儿相关危险因素。方法将2013-2014年常州市妇幼保健院新生儿科NICU收治的142例极早产儿为研究对象,排除先天畸形;随机抽取142例足月儿(胎龄≥37周)作为对照。结果多因素条件Logistic回归分析显示,男性胎儿、试管婴儿、多胎、胎盘异常、母亲有基础疾病、妊娠并发症、胎位不正、羊水污染、宫内感染是极早产儿的危险因素(OR>1),胎儿出生日期、母亲胎膜早破、保胎史、疤痕子宫、不良生育史在早产儿组和足月儿组的差异无统计学意义(P>0.05)。结论极早产儿的发生与男性胎儿、试管婴儿、多胎、胎盘异常、母亲有基础疾病、妊娠并发症、胎位不正、羊水污染、宫内感染相关。更多还原

【Abstract】 Objective To explore the related risk factors of 142 extremely preterm infants. Methods A total of 142 extremely preterm infants treated in NICU of the hospital from 2013 to 2014 were selected as study objects,the extremely preterm infants with congenital malformations were excluded; 142 full-term infants( fetal age≥37 weeks) were selected randomly as control group. Results Multivariate conditional logistic regression analysis showed that male fetuses,test-tube baby,multiplets,placental abnormality,maternal basic diseases,pregnancy complications,malposition,amniotic fluid contamination,intrauterine infection were risk factors of extremely preterm infants( OR>1).There was no statistically significant difference in the date of birth,maternal history of premature rupture of fetal membrane and fetus protection,scar uterus,and poor fertility history between premature infants and full-term infants( P>0. 05). Conclusion The occurrence of extremely premature infants is correlated with male fetuses,test-tube baby,multiplets,placental abnormality,maternal basic diseases,pregnancy complications,malposition,amniotic fluid contamination,and intrauterine infection.更多还原
