Abstract

A Clinical observation has been made on 217 cases of postterm pregnancy out of 4,830 cases delivered at the department of obstetrics and gynecology, Buchon Sejong Hospital for the past 5 years from Sep. 1, 1982 to Aug. 31, 1987. And the same numbers of fullterm deliveries conducted in the same period were used as control group on the basis of maternal age, parity and payment method. A pregnamy lasting 42 weeks or more from the first day of the last menstrual period was selected as criteria of postterm.
The purpose of this study were; (1) to evaluate the effect of prolonged gestation upon the pregnant woman and fetus; and (2) to delineate a plan for the management of patients in whom pregnancy is prolonged past the expected date of confinement.
The incidence of postterm pregnancy was 4.49%. The following factors were analysed in the posterm delivery and control group of fullterm delivery; the numbers of antenatal care, the complications during pregnancy, fetal distress, total duration of labor, delivery method, birth weight, Apgar scores(1 min and 5 min). the placental weight, maternal complications during and after delivery and fetal complications.
The results obtained in this study were; high fetal distress rate, higher proportion of prolonged labor, higher incidence of Cesarian section, higher proportion of larger baby(Birth weight over 3500gm), lower Apgar score(0-7) in 5 min and more complications during and after delivery were found in positerm delivery group.
