Abstract

There were 544 perinatal deaths out of 11,336 single births who were delivered at Severance, Chonju Presbyterian and Wonju Christian Hospitals. The Perinatal mortality rates were calculated at fetal deaths of 20 or more weeks?gestation plus neonatal deaths under 28 days after birth. We made a comparative studies of classification about the perinatal and neonatal mortality reports on the literatures. The results were summarized as follows; 1. Concerning the mortality rate related with birth weight and gestational age, we have observed that the mortality rate decreased by increasing birth weight in a certain gestational age group and by increasing gestational age in certain birth weight, as reported on several literatures. 2. Among the 436 cases weighing 1,001gm or more and with 28 week or more of gestational age, the incidence of deaths weighng 2,501gm or more was 44.8% and with 38 week or more of gestational age was 50.9%. We have been observed, not only able to take care effectively, but also better prognosis, by introducing intensive care to full-sized and term births than low-birth weights as pre-trm.
