胎膜早破后胎儿呼吸运动变化预测宫内感染的研究

The relationship between the fetal breathing movements and intrauterine infection in patients with premature rupture of the membranes

目的观察未足月胎膜早破 (PPROM)孕妇胎儿呼吸运动并分析FBM变化是否可以预测早期宫内感染。方法选择PPROM (PPROM组 )、足月胎膜早破 (TPROM组 )及正常足月孕妇 (对照组 )进行FBM检查并评分。收集羊水检测病原体。结果PPROM组及TPROM组FBM评分≤ 1者高于对照组 (P均 <0 .0 5 ) ,但其平均羊水指数小于对照组(P均 <0 .0 5 )。胎膜早破组中FBM≤ 1者及FBM =2者羊水病原体阳性率无差异。结论胎膜早破孕妇 ,无论足月或未足月 ,FBM均减少 。

Objective To observe the fetal breathing movement(FBM)in patients with preterm premature rupture of the membranes and analyse the correlation between FBM and early intrauterine infection.Methods FBM was checked and scored in preterm preterm rupture of the membranes(PPROM)group,term premature rupture of the membranes(TPROM)group and normal control group.Amniotic fluid(AF)was analyzed for pathogens.Results FBM score≤1 in PPROM and TPROM group was higher than in control group(P<0.05)but AF index was lower than control group.AF positive rates for pathogen in both FBM≤1 and FBM=2 were the same.Conclusion FBM is reduced in PROM patients whether at term or not,but the reduced FBM has nothing to do with early intrauterine infection while is related with less AF volume.
