Authors studied the mortality rate by birth weight, gestational period, sex, time after birth, Apgar score, mode of delivery and cause of death. The result are as follows: 1)The early neonatal mortality rate was, in average, 15.1 among 1,000 live births. 2) Mortality sex ratio on male to female was 1.39 : 1. 3)According to the birth weight, the lowest risk of mortality rate (2.0/per 1,000 live birth) was in 3,000~3,500 gm and according to the gestational period, the lowest risk of mortality rate (2.7~3.1/per 1,000 live birth) was in 38~42 week gestation. 4) Number of low birth weight (less than 2,500 gm) infants were 1,434 (7.7% of totallive births), and Number of deaths in the totali low birth weight infants were 234 (83% of total deaths). 5)58.2% of neonatal death occured within 24 hours after birth and thereafter the rate decreased. 6)65% of total deaths showed under 4, in 1 Minute Apgar score. 7)By the mode of delivery, the highest mortality rate was seen in breech delivery; 11.5% and others showed that normal spontaneous delivery 1.7%, Vaccum delivery 0.4%, Cesarean section 1.6%. 8)The most common cause of death was abnormal ventilation(32.3%), which was followed by prematurity, congenital anomalies, infection and others.
