Abstract

The purpose of this study is to estimate early neonatal mortality rate in relation to obstetric factors. The early neonatal mortality rate was estimated on live births with a gestational period more than 28 weeks who died during the first 7 days of life in Ewha Womans University Hospital fro-m Jan. 1974 to Dec. 1978. During this period, there were 8218 single births and 127 early neonatal deaths. 1. We had 127 deaths out of 8218 single births, and early neonatal mortality rate came to 15.5 per 1000 live births. 2. The early neonatal mortality rate was increased in cases of maternal age over 40, higher in multipara, who had delivered more than 4 times, who had frequent abortions (more than 5 times) and it was also higher in para-one than para-two. 3. The early neonatal mortality rate was 7.9 times higher in abnormal presentation of fetus than normal one. 4. There was no significant difference in early neonatal mortality rate between spontaneous vaginal delivery and Caesarian section delivery, but significant high mortality rate was noted in breech delivery. 5. In cases of anemic mother (Hemoglobin less than 10 gm%, Hematocrit less than 32%), the early neonatal mortality rate was 2.8 times higher than non-anemic group. 6. The early neonatal mortality rate of babies from mothers without antenatal care was 3 ti-mes higher than that of mothers who had. 7. Hypertensive disorders in pregnancy was present in 15.8% of all live births and early neo-natal mortality rate was 10.8. The mortality rate was 6.5 times higher in chronic hypertensive vascular disorder with toxe-mia than in preeclampsia and 3.7 times higher in eclampsia than in precclampsis. 8. The obstetric complication which increased early neonatal mortality rate were polyhydra-mnios, amnionitis, abruptio placentae etc.
