本文对1987～1992年住院分娩的138例过期妊娠,产前采用 B 超动态测量羊水暗区及动态检测24小时尿 E_3值,并将监护情况与产后羊水量的实际情况进行了对比分析,结果表明羊水量过少组其 B超测量羊水暗区≤3cm 的阳性率为84.62%;24小时尿 E_3值<35μmol(10mg)明显增多,占74.36%;过熟儿综合征发生率也明显增多,占74.36%,三者呈正相关。因此,认为联合应用 B 超测量羊水暗区及24小时尿 E_3值检测来监护过期妊娠,方法简便,孕妇无痛苦,准确性高,值得推广应用。
In this paper, 138 cases of obstetric delivery in hospital from 1987 to 1992, prenatal use of B-ultrasound dynamic measurement of dark areas of amniotic fluid and dynamic detection of 24-hour urinary E_3 values, and monitoring the situation and the actual situation of postpartum amniotic fluid were compared, the results The results showed that the positive rate of B-ultrasonographic measurement of amniotic fluid dark area ≤3cm was 84.62%; E_3 value of 24-hour urine <35μmol (10mg) was significantly increased, accounting for 74.36%; the incidence of overmature infantile syndrome was also significantly increased, Accounting for 74.36%, the three were positively correlated. Therefore, the combined application of B-measurement of amniotic fluid dark area and 24-hour urine E_3 detection to monitor outdated pregnancy, the method is simple, pregnant women without pain, high accuracy, it is worth promoting the application.
