妊娠高血压综合征孕妇红细胞压积水平对胎儿的影响

本文作者对２６８例妊高征患者ＨＣＴ，尿Ｅ／Ｃ比值及羊水最大平段及对胎儿的影响进行分析。结果表明，随妊高征病情加重其ＨＣＴ值逐渐增高；当ＨＣＴ≥３５％时，尿Ｅ／Ｃ比值降低，羊水量减少，胎儿窘迫，新生儿窒息，低体重儿及围产儿死亡率增加。我们认为ＨＣＴ水平升高，降低了子宫胎盘流量，导致胎盘功能低下及影响胎儿预后。因此，监测妊高征患者ＨＣＴ水平对了解好高征的发展，指导治疗及预测胎儿预后是非常必要的。

Effect on fetus of HCT levels in pregnant women with pregnancy inducing hypertension

This paper analysed hematocrite(HCT),urinary E/Craio,maximum diameterof amniotic fluid and the influence upon fetus in 268 patients with pregnancy inducing hypertension(PTH).The results indicated that HCT levels increased gradually with degree of PIH; when HCT≥35%,such conditions occurred as low urinary E/C ratio ,low volume of amniotic fluid ,high inci-dences of fetal distress, neonatal asphyxia,low birth weight and increascd perinatal death.We thoughtthat increasing HCT levels might decrease volume of blood flow of uterus─placenta,which inducedthe placental disfunction and affected fetal prognosis.Therefore,it is necesary to monitor HCT levelsin patients with PIH in order to understand development of PIH, direct its treatment and predict fetal prognosls.
