摘　　要：目的　本课题旨在探讨妊娠晚期胎儿脐血流等参数与胎盘生理或病理性改变的线性关系 ,用于评估胎盘功能和围产儿预后。方法　通过对 6 0例妊娠晚期 (孕周为 39± 2weeks)的孕妇 ,经彩色多普勒超声 (以下简称彩超 )检测胎儿脐血流和腹主动脉血流参数 ,分别计算并拍片记录其血流阻力指数RI、搏动指数PI、血流收缩期与舒张期比值S/D ,并进行统计学分析。随机抽取正常妊娠组 ,分娩后新鲜胎盘共计 2 0例 ;异常妊娠组分娩后新鲜胎盘共计 7例 ,统一标准做病理检验。对 6 0例产后新生儿评分追踪记录。结果　胎儿脐血流RI =0 .5 6± 0 .0 8,S/D =2 .1± 0 .4,胎盘 (功能 )成熟老化程度为II° ,病检胎盘绒毛模板变性较少 ,绒毛水肿、结节、钙化为少量 ;胎儿腹主动脉血流PI=1.48± 0 .49,S/D =3.1± 0 .8时 ,提示胎儿宫内状况良好 ,新生儿产后评分多为 9～ 10cent/min。结论　胎儿脐血流与胎盘功能存在一定线性关系 ,其血流参数可作为评价胎盘功能与围产儿预后的一项指标 。Purpose To investigated the linear relationship between the late pregnancy umbilical artery and placenta physiological on pathological change and evaluate the placenta function and the perinata pregonoses. Methods Through to people of late pregnancy umbilical artery and abdominal aorta were investigated, using color Doppler ultrasound, the resistance index(RI), the passe index(PI) and the peak syslolis/diastolic ratio(S/D) were calculated, photographed and analyoised statistically. 20 placenta of aormal pregnanul and 7 placenta of abnormal pregnancy were choose at random and were checked pathologically by the same standard, to record the go cases of neonate Apgar score. Results Fetus umbilical artery blood stream RI=0.56±0.08, S/D=2.1±0.4, the matuse degree of the placenta was II°. Few villi were degenerated and had nodosity, bister and calcification, fetus abdominal aorta blood stream PI=1.48±0.49, S/D=3.1±0.8, fetus in good condition, neonate apgar score most was 9～10cent/min. Conclusion There was linear relationship between the fetus umbilical artery and placenta function. [
