诊断死胎的各种方法,如自觉胎动消失;听胎心或采用胎儿心电图;X线摄片;采用多普乐超声或B型超声诊断等方法,均可能发生误诊或存在某些缺点。目前诊断宫内死胎最灵敏与特殊的方法是超声实时成像(real-time ultrasonography),但是不是所有医院都能采用的。因此,很需要一种简单而具有高度判断价值的实验方法来诊断胎儿是否存活。 Kerenyi及Sarkozi(1974)测定羊水肌酸激酶(creatine kinase,简称CK)决定胎儿是否存活是很有价值的试验,但未被重视。本文目的在于:(1)进一步证实Kerenyi及Sarkozi的发现;(2)分析不同情况的孕妇与胎儿对羊水CK活性的影响;(3)研究血与胎粪污染羊水内CK
Various methods of diagnosis of stillbirth, such as the disappearance of conscious fetal movement; to listen to fetal or fetal ECG; X-ray; using Doppler ultrasound or B-mode ultrasound diagnosis and other methods, may be misdiagnosed or there are some shortcomings. Currently the most sensitive and specific method of diagnosing intrauterine fetal death is real-time ultrasonography, but not all hospitals can use it. Therefore, there is a great need for a simple but highly discriminatory experimental method to diagnose the survival of a fetus. Kerenyi and Sarkozi (1974) determined that creatine kinase (amniotic fluid creatine kinase, CK) is a valuable test to determine whether the fetus survived, but not valued. The purpose of this paper is: (1) to further confirm the findings of Kerenyi and Sarkozi; (2) to analyze the different conditions of pregnant women and fetuses on amniotic fluid CK activity; (3) to study the blood and meconium-stained amniotic fluid CK
