妊娠合并高血压是最常见的围产期病死率原因之一,胎儿受累主要因子宫胎盘功能不全,已应用各种生物化学和生物物理技术对胎儿进行监护,其中胎心率测定(FHR)是最广泛使用的方法。许多作者报告晚期减速是胎儿窘迫的信号(Slomka等,1981)。进行性子宫-胎盘功能不全时,FHR变异逐渐减少是胎儿脑组织受损甚至濒于死亡的不祥信号,对监护高危妊娠具有价值。本文旨在研究FHR短期变异的程度,鉴别指数(DI)预测胎儿窘迫的临床价值。研究对象为高血压妊娠202例((?)28孕周),分为四组:轻度子痫前期65例,重度子痫前期58例,慢性高血压44例和慢性高血压合并子痫前期35例。全部胎儿均行胎心产力监护。围产期死亡5例(2.5%):2例早产和窒息,1例支气管肺发育异常,1例18三体,1例横膈发育不全。产期胎儿窘迫63例,每例至少有以下两项体征:Apgar评
Hypertension in pregnancy is one of the most common causes of perinatal mortality, the main cause of fetal involvement in uterine placental dysfunction, the fetus has been monitored using a variety of biochemical and biophysical techniques, including fetal heart rate determination (FHR) is The most widely used method. Many authors report late deceleration as a sign of fetal distress (Slomka et al., 1981). Progressive uterus - placental insufficiency, FHR mutation is gradually reduced fetal brain tissue damage or even near-death ominous signal, the care of high-risk pregnancy has value. This article aims to investigate the extent of short-term variation in FHR and the clinical value of discriminative index (DI) in predicting fetal distress. The study included 202 pregnant women with hypertension (28 gestational weeks), divided into four groups: 65 in mild preeclampsia, 58 in severe preeclampsia, 44 in chronic hypertension, and chronic hypertension in preeclampsia 35 cases. Fetal heart rate monitoring of all fetuses. Perinatal death in 5 cases (2.5%): 2 cases of premature birth and asphyxia, 1 case of bronchopulmonary dysplasia, 1 case of 18 trisomy, 1 case of diaphragm hypoplasia. 63 cases of fetal distress during delivery, each case has at least the following two signs: Apgar evaluation
