Thirty pregnant women in the third trimester of pregnancy in whom fetal movements were reduced up to cessation, for at least 12 hours, were monitored for FHR. The FHR 12-48 hours after the cessation of fetal movements was pathological in 21 cases and normal in 9 cases. The most frequent pathological FHR changes were loss of beat to beat variation and variable decelerations. In the following 48 hours another four cases showed pathological FHR changes. One to four days before the reduced fetal movements only six out of 15 cases showed pathological FHR changes which were L.B.B.V. Meconium was found in only 50% of the cases. It is suggested that pregnant women, especially high risk cases, should record fetal movements as a screening method. FHR monitoring is also a valuable method for detecting antenatal fetal distress, and should be used as an adjunct to fetal movements recording. When acute fetal distress has been established by MAS alone or with FHR change, the fetus should be promptly delivered.
对30名妊娠晚期孕妇进行了监测，这些孕妇的胎动减少直至停止至少12小时，监测其胎心率（FHR）。胎动停止后12 - 48小时，21例胎心率异常，9例正常。最常见的异常胎心率变化是逐搏变异消失和可变减速。在接下来的48小时内，又有4例出现异常胎心率变化。胎动减少前1至4天，15例中只有6例出现异常胎心率变化，表现为左束支传导阻滞变异（L.B.B.V.）。仅50%的病例发现有胎粪。建议孕妇，尤其是高危病例，应记录胎动作为一种筛查方法。胎心率监测也是检测产前胎儿窘迫的一种有价值的方法，应作为胎动记录的辅助手段。当单独通过羊水吸入综合征（MAS）或伴有胎心率变化确诊急性胎儿窘迫时，应立即分娩胎儿。
