In terms of the length of gestational period, obstetric maternity records of

5,845 pregnant women whose pregnacies terminated between 1974 to 1976, were

reviewed. Comparison were also made with the results of 1969-1973 study series

reported from Yonsei Medical Center.

1) The annual distribution of the total number of deliveries was as follows.

1974-1976 series 1969-1973 series

1974 1975 1976 Total Average Total Average

No. of

delivery 2,080 2,065 1,700 5,845 1,948 11,436 2,287

% 35.6 35.3 29.1 100 - 100 -

2) 84.12% of the pregnancies terminated at 37 to 42 weeks of gestation. Thus

37 - 42 weeks of gestation appeared to be the most adequate period.

3) The average length of gestation was on the decrease with the age of the

mothers and the differences of means were statistically signigicant when the age of

the mothers was over 35. It was found that the women in the age between 25 and 29

occupied 53.94% of total pregnancies terminated and their mean length of gestation

was 38.80 ± 0.76 weeks.

4) Recently the annual total number of pregnancies in private service tended to

be increased progressively in contrast with clinic case. The annual mean length of

gestation in private service was closer to term.

5) The proportion of hypertensive disorders in pregnancy among the total

pregnancies terminated was as follows :

Preeclampsia, mild form 5.53%

Preeclampsia, severe form 2.69%

Antepartal eclampsia 0.69%

Intrapartal eclampsia 0.14%

Postpartal eclampsia -

The average duration of gestation in severe hypertensive disorders in pregnancy

were the most frequent in the early period of the third trimester.

The distribution was as follows :

weeks of gestation standard deviation

Preeclampsia, mild form 38.12 ±0.78

Preeclampsia, severe form 37.10 ±0.96

Antepartal eclampsia 33.88 ±2.49

Intrapartal eclampsia 34.36 ±0.92

Postpartal eclampsia - -

6) At birth the percentage of male was 52.15%. There are no significant

differences in the length of gestation in the sex of babies.

7) The proportion of perinatal death to total delivery number is as follows :

Still births 1.61%

Died 1st 24 hrs. 1.08%

Died 25-72 hrs. 0.34%

Died 4-7 days 0.03%

The perinatal death was directly related to the length of gestation at delivery.

8) The weight of newborn infants was distributed mainly between 3,000 and 3,499

gm. As the pregnancy got to 38 weeks of gestation, the baby weight was between

2,500 and 2,999 gm.

9) The risk of the premature delivery was increased with number of previous

abortion, whether spontaneous or induced, being done. The risk of the premature

delivery also was directly related to the number of previous history of premature

delivery.

10) 77.83% in the range of 37-42 weeks of gestation but 63.82% and 52.71%

respectively when the length of gestation was below 36 or above 43 weeks.

11) The Apgar score at one minute and five minutes of neonate who was born in

between 37 to 42 weeks of gestation was most favorable one.
