胎儿宫内监测,是降低围产儿发病率及死亡率的主要方法,对临床有着重要意义。现将几种临床预测方法介绍如下。一、胎动监护胎动是预测胎儿安危的最简单方法。妊娠16～20周后,孕妇可感觉有胎动,此时可自行计数;亦可用 B 型超声波测量胎动。妊娠晚期可根据形状、持续时间、振幅,分三类测量胎动:①翻滚—胎动复杂,平均持续时间为14秒。②简单胎动—单独躯体或肢体动,持续时间平均为3秒。③高频率的胎动—孤立的或重复的动,持续时间平均为0.12～
Intrauterine fetal monitoring is to reduce the incidence of perinatal mortality and the main method has clinical significance. Now several clinical prediction methods are described below. First, fetal movement monitoring fetal movement is the most simple way to predict fetal safety. 16 to 20 weeks after pregnancy, pregnant women can feel fetal movement, this time can be their own count; also available B-type ultrasonic measurement of fetal movement. Late pregnancy can be based on shape, duration, amplitude, divided into three categories of fetal movement measurement: ① roll - complicated fetal movement, the average duration of 14 seconds. ② simple fetal movement - a single body or limb movements, the average duration of 3 seconds. ③ high frequency of fetal movement - isolated or repetitive movements, the average duration of 0.12 ~
