We have used Prostaglandin (P) and Oxytocin (Ox) comparatively for induction of labor.
P and Ox were applied to primi para or multi para after 39 weeks gestation respectively.
(P: 51 cases) (Ox: 211 cases)
(Method)… in numerical order
1) one Delivarin tablet, 3 times, one each hour.
2) soap enema: 500ml.
3) 1, 000mmg P or 10 i. u. Ox in 5% dextrose solution, dripped at the rate of 40 drops a minute.
4) after labor pains induced and water bag distended, artificial rupture of the water bag was done.
(Result)
1) There is no difference between P and Ox on duration of delivery, numbers of asphyxia of new born baby and obstetric operations such as cesarian section, vacuum extraction and forceps delivery.
2) In case of using with P, bleeding volume in 3rd stage of labor is less than Ox with primi para.
3) Pattern of labor pains induced by P is more similar to natural than Ox's.
4) P is more effective to soften unripe hard cervix of uterus than Ox and more useful to primi para.
(Discussion)
From results above described, it is suggested that P without abnormal contraction works more naturally on uterus thank Ox and works to unripen and harden cervix of uterus effectively; thus using P with primi para, many profits can be expected.
