고위험임신군에서 산전 태아감시의 임상적 의의 = Clinical Significance of Fetal Monotoring in High Risk Pregnancy

다국어 초록 (Multilingual Abstract)

For the antepartal assessment of fetal well-being in high risk pregnancy, the fetal heart rate monitoring has been found to be clinically efficacious. From November 1, 1980, to April 30, 1982, 483 nonstress test (NST) and 64 contraction stress test (CST) were performed on 399 women with high risk pregnancy. The results of this study were as follows: 1. The most common indication for NST was hypertensive disorders during pregnancy (21.1 %). 2. The mean gestational age in antepartal fetal monitoring was 40.04 weeks, and the mean birth weight in delivered cases was 3,050 gm. 3. Among 483 NST, reactive results were found in 411 cases (85.1 %), nonreactive in 69 cases (114.3 %), and unsatisfactory in 3 cases (0.6 %). 4. Among 64 CST, reactive patterns were found in 8 cases (11.6 %), and among 56 cases with completed CST, negative results were found in 32 cases (57.1 %), suspicious in 3 cases (5.4 %), and positive in 21 cases (37.5 %). 5. Low Apgar score was found in 6 cases (1.8 %) out of 339 normal fetal monitoring group (NFMG), and 11 cases (45.7 %) out of 24 abnormal fetal monitoring group (AFMG), respectively (P < 0.005). 6. Fetal distress during labor was found in 6 cases (1.8 %) out of 339 NFMG), and 19 cases (75.0 %) out of 24 AFMG, respectively (P < 0.005). 7. Of 339 NFMG, one case (0.3 %) had cesarean section due to fetal distress while 8 cases (33.3 %) of 24 AFMG had cesarean section (P < 0.005). 8. While no fetal death in uterus and 8 neonatal deaths (2.4 %) were found in 339 NFMG, 8 perinatal deaths (33.3 %) including 3 FDIU and 5 neonatal deaths were found in 24 AFMG (P < 0.005). 9. There were no false reactive case in NST and false negative case in CST. False positive rate in CST was 23.8 %.
