Risk Factors of Intraventricular Hemorrhage in Preterm Infants Born at 34 Weeks of Gestation OR Less

摘要

目的：本研究提出了识别可能的围产期危险因素与脑室出血（IVH）相关的早产儿≤妊娠34周后早产胎膜早破（PPROM）。
　　方法:对137例早产儿出世≤孕34周胎膜早破后进行超声筛查数据的回顾性分析。ofivh进行所有的infants.33 IVH的婴儿（病例组）和104 infantswithout IVH（对照组）进行比较来确定。协会风险因素与新生儿IVH的评价通过单因素和Logistic回归。
　　结果:IVH早产儿出世后≤孕34周胎膜早破的发生率为24.1％。母亲的绒毛膜羊膜炎的发生率为43.8％。通过单因素分析，孕周，出生体重，窒息复苏，母亲的绒毛膜羊膜炎，胎儿窘迫，羊水指数和胎膜出生的潜伏期是两组之间的显着不同。采用Logistic回归分析，小胎龄，低出生体重，窒息复苏，母亲的绒毛膜羊膜炎是IVH早产儿BOM≤妊娠34周后未足月胎膜早破的独立危险因素。
　　结论:小胎龄，低出生体重，窒息复苏和绒毛膜羊膜炎是母亲在妊娠34周以内由PPROM早产儿IVH的独立危险因素。
