A Clinical Study for Intrauterine Fetal Death / 대한산부인과학회잡지

ABSTRACT

The intrauterine fetal death(IUFD) is the death of the fetus prior to complete expulsion or extraction from its mother when the fetus is over 20 weeks gestation or weights more than 500 gm. This is a clinical study of 262 cases of IUFD and 262 control cases among 18542 deli-veries at Chung Goo Sung Sim Hospital during 10 years from 1987 to 1996. The results obtain-ed were as follows 1. The incidence of IUFD was 1.41%. 2. The risk of IUFD was high in women older. 3. The risk of IUFD was high in women with parity of three or more, there was a previous history of IUFD in 11.2% of the IUFD cases and in 6.3% of the control cases, but there was no difference between the two groups of women in history of spontaneous abortion. 4. The sex ratio of male versus female was 1.241 in the IUFD cases, 1.111 in the control cases. 5. The low birth weight and preterm infants were much more frequent in the IUFD cases. 6. The mode of delivery IUFD was induced labor(77.5%), laparotomy(12.2%), spontaneo- us delivery(10.3%). The indications for laparotomy were placental abruption, placenta previa, transverse lie, previous cesarean section status, cephalopelvic disproportion and uterine rupture. 7. The most common cause of IUFD was unexplained causes(45.1%). 8. There were 67 cases(25.6%) of maternal complication, and the most common complica- tion was fever(35.8%). 9. In the incidence of abnormal coagulation test, the low platelet count(14 seconds) was 7.2%, the prolonged partial thr- omboplastin time was 1.0%, the hypofibrinogenemia(40 ug/ml) was 8.4%. 10. The risk of IUFD was lowered as the number of antenatal care was increased.
