Clinical Study for Fetal Death in Utero / 대한산부인과학회지

ABSTRACT

OBJECTIVE: The purpose of this study was to evaluate the incidence, causes and maternal complications in cases of fetal death in utero (FDIU). METHODS: This is a clinical study of 224 cases of FDIU among 10,582 deliveries at 00 University Hospital during January 1990 to December 2004. All the clinical informations were obtained by reviewing medical records retrospectively. RESULTS: The average incidence of FDIU was 2.1%. The mean age of mothers with FDIU was 28.5 years old. The mean gestational age was 30.4 weeks and mean weight of dead fetus was 1442 gm. The causes of FDIU were placenta abuptio (14.3%), severe preeclampsia (13.4%), congenital anomalies (9.4%), severe intrauterine growth restriction (IUGR, 9.4%), nuchal cord (6.7%), chrioamnionitis (5.8%). However the causes of FDIU were largely unknown (18.8%). The modes of delivery were induced labor (65.2%), laparotomy (26.8%), spontaneous labor (8.0%). The most common indication of laparotomy was placenta abuptio (36.7%). There were 66 cases (29.5%) with maternal complications and common complications were hemorrhage (11.2%), fever (8.5%), DIC (5.8%). The incidence of hypofibrinogenemia (<150 mg/dL) was 14.3%. CONCLUSION: The most common suspected causes of FDIU were placenta abruptio, severe preeclampsia and the causes could not be determined in 42 cases (18.8%). The proper prenatal care should be taken of fetuses on the basis of risk factors of antepartum and intrapartum so that unnecessary intrauterine fetal death might be able to be prevented.
