摘要 目的评价血液动力学指标预测未足月胎膜早破胎儿-胎盘系统动脉血流测量评价胎儿宫内情况的价值。方法用彩色多普勒超声检测279例未足月胎膜早破分娩的孕妇胎儿脐动脉(UmA)、大脑中动脉(MCA)、肾动脉①A)的血流速度渡型删s),并且分娩时测定新生儿脐动脉血气及胎盘送病理检查。结果本研究将UtA、UmA、RA及MCA的RI值与脐动脉血pH、PaO2、PaCO2值作了相关性分析,UmA的RI值及S/D与PaO2、pH值呈负相关,与PaC02呈正相关,MCA则正好与前两者相反。当胎膜早坡丸其合并胎盘绒毛膜羊摸炎时,通过神经体液调节,母体-胎盘-胎儿循环的血液动力学有改变,胎盘出现炎症改变时脐动脉S/D的变化有统计学相关意义。结论未足月胎膜早破胎儿-胎盘系统动脉血流测量.胎儿.血液动力学变化与缺氧及酸碱平衡失调呈良好相关性,可预测胎儿缺氧及酸中毒的程度。胎盘出现炎症改变时脐动脉S/D的变化有统计学相:廷意义。
