Abstract

OBJECTIVE
The purpose of this study was to evaluate intrauterine fetal death and elucidate the etiology of intrauterine fetal death.
METHODS
This is a clinical study of 74 cases of intrauterine fetal death (IUFD) among 5,523 deliveries at Soonchunhyang University Hospital during Jan. 1998 to Apr. 2003.
RESULTS
The overall incidence of IUFD was 1.34%. And the age distribution of mother with IUFD was between 19 to 44 year old and was highest in the 25 to 29 year old age group (39.1%). The parity of mothers with IUFD was the highest in nulliparous group (78.3%) and there was a decreased tendency with high parity. There were 47 cases (63.5%) with previous history of abortion and 2 cases (2.7%) with previous history of IUFD. The highest incidence rate of IUFD was shown at 20-24 weeks of gestation (48.6%) and in the fetus weighted less than 1,000 gm (59.5%), and the sex ratio of male versus female fetus was 1:1.07. The modes of delivery were labor induction (54.1%), laparotomy (18.9%), spontaneous labor (27.0%). The indication for laparotomy was placental abruption, placenta previa, previous cesarean section state. The etiology factors of IUFD were unexplained causes (55.4%), cord complication (12.2%), placental abruption (9.4%), placenta previa (9.4%) in order.
CONCLUSION
The causes of IUFD were unexplained, cord complication, placental abruption in order. So, the proper antenatal care should be taken of fetuses on the basis of risk factors of antepartum and intrapartum.
