Abstract

Introduction: Since most of cases of pregnancy termination are induced by oxytocin of
which needs special care, much time, costs, and it has side effects such as water toxicity
especially in prolonged inductions trying to find suitable replacement for oxytocin is
necessary. The aim of this research is compared on oxytocin with misoprostol in the second
trimester of pregnancy gynecology ward of academic hospitals in Mashhad. (Imam Reza –
Ghaem – Hazrat Zeinab)
Materials and Methods: In this prospective case – control study, we divided 125 pregnant
women in the second trimester to two groups.
 Pregnancy termination in the case group was induced by administration 3 100 µg oral tablets
of misoprostol and one vaginal misoprostol tablet.
If there wasn’t any uterine contraction we used one oral tablet every 3 hours and a vaginal
tablet every 4 –6 hours for 48 hours.
 In the control group pregnancy termination was induced by oxytocin. 50I/U of oxytocin was
diluted with 500CC Ringer and infused in 3 hours then there was a resting period for l hour
and then we increase 50I/U oxytocin in 500CC Ringer untile maximum 300I/U in 500 CC
Ringer. Our plan was 3 hours of induction and an hour resting until beginning of contraction
or no responding after 48 hours induction.
Another method of delivery induction was replaced, if no contraction was observed after 48
hours in both groups.
Results: Labor contraction and pregnancy termination happened sooner in the misoprostol
group than oxytocin group. (p = 0.001)
Placental retention and costs were less in the case group (p<0.05). Fever, bleeding,
gastrointestinal tract complications and uterine rupture had no difference in both groups.
(p>0.05)
Conclusion: Misoprastol alone induced delivery sooner when was compared to oxytocin, in
the second trimester and it also had less cost and less side effects. Besides it dose not need
intensive nurse care. So we recommend misoprostol for pregnancy termination in the second
trimester.
