作者报道在大量产前胎心图测试中发现4例患者出现意外和特殊的结果。450例患者中有4例胎心图形态如图Ⅰ所示。病例1:24岁初产妇,妊娠30周零5天发生先兆子痫征象,血压150/100伴有蛋白尿。此前确无妊娠合并症。此时考虑胎儿亦有生长停滞现象。入院休息13天后获得以上所示之胎心图。在此期间用苄胍(Bethanidine),氯压定(Clonidine),及肼苯哒嗪(hydrallazine)以控制进行性高血压。蛋白尿增至7.22克/24小时,24小时雌激素排泄量自9.2毫克下降至4.8毫克,同时肌酐廓清率自70毫升减少至45毫升/分钟。次日胎动停止,胎心消失。第二天以后病人自然临产,娩出一男性死胎。胎龄33周,体重1250克。羊水被胎粪严重污染,此婴体重较同期正常婴儿低120克即1/10。产后母体检查未发现任何异常。
The authors report that unexpected and specific results were found in 4 patients in a large number of prenatal fetal heart map tests. Four of the 450 patients had a pattern of fetal heart shape as shown in Fig. Case 1: 24-year-old primipara, pregnancy 30 weeks and 5 days preeclampsia signs, blood pressure 150/100 associated with proteinuria. There was no previous pregnancy complications. At this point consider the growth of the fetus also stagnant. The fetus heart map shown above was obtained after 13 days of hospital rest. During this period, Bethanidine, Clonidine, and hydrallazine were used to control progressive hypertension. Proteinuria increased to 7.22 g / 24 hours, estrogen excretion decreased from 9.2 to 4.8 mg at 24 hours, and creatinine clearance decreased from 70 to 45 ml / minute. The next day fetal movement stopped, fetal heart disappeared. The second day after the patient natural abortion, giving birth to a male stillbirth. 33 weeks gestational age, weight 1250 grams. Amniotic fluid is heavily contaminated with meconium, the baby weight 120 grams lower than normal over the same period that is 1/10. Postpartum maternal examination found no abnormalities.
