诊断胎儿宫内窘迫的方法分生化和生物物理二大类。本文讨论几种常用的诊断方法。 1 胎动计数 Samueoff和Sadovsky研究双胎胎动规律,对33例双胎与127例单胎,自26至40周胎动次数进行比较,其方法为每天3次,每次30分钟。结果:单胎妊娠20周时,平均200次/天(12小时),32周575次/天,为高峰,以后逐周减少,到40周为282次/天。双胎:27周已达高峰,774次/天(而单胎在此孕周493次/天,P<0.05),之后双胎胎动数也逐周下降,到40周为224次/天;最
Diagnostic methods of fetal distress sub-biochemical and biophysical two categories. This article discusses several commonly used diagnostic methods. 1 fetal movement count Samueoff and Sadovsky twins fetal movement law, 33 pairs of twins and 127 singletons, from 26 to 40 weeks of fetal movement frequency comparison, the method is 3 times a day for 30 minutes each. RESULTS: Twenty-one-week pregnancies averaged 200 beats / day (12 hours) and 575 beats / day at 32 weeks, peaked and then decreased weekly to 282 weeks / week at 40 weeks. Twins reached a peak at 27 weeks (774 beats / day, while 493 beats per singleton at this gestational day, P <.05). After that, twins’ motions also decreased weekly, reaching 224 weeks at 40 weeks. most
