胎动监测意义的再评估

胎动计数是常用的胎儿产前监测方法之一，胎动正常模式的改变预示着胎儿宫内状态异常。研究发现，胎动减少常是胎儿窘迫的首要征象，与死胎、胎盘功能不全、胎儿生长受限等不良妊娠结局相关；妊娠32周后胎动增加是正常的胎动规律，但单次过度运动与死胎有关。临床上通过孕妇自数胎动的方式初步评估胎儿宫内安危以便早期发现胎儿异常，减少不良妊娠结局的发生，这种方法具有经济、方便、简单、能反映部分问题的特点，但是较为主观，孕妇个体感受的胎动差异较大。

Reevaluation of the significance of fetal movement monitoring.

Fetal movement counting is one of the common methods for fetal prenatal monitoring.The changes of the normal pattern of fetal movements（FM）indicate abnormal fetal status in uterus.Studies have found that reduced fetal movement is the primary sign of fetal distress，which is associated with adverse pregnancy outcomes such as stillbirth，placental insufficiency，and fetal growth restriction.Increased fetal movement after 32 week's gestation is regular，but a single episode of vigorous FM increases risk of stillbirth.Clinically，fetal safety is preliminarily evaluated by counting numbers of FM to find abnormalities of fetus early and decrease adverse pregnancy outcomes，which is economical，convenient，and simple.However，this method is subjective，due to the different sensitiveness of pregnant women.
