Mid-trimester termination of pregnancy-comparison of sublingual with vaginal misoprostol

ABSTRACT

This paper compares the efficacy, side effects and patient's satisfaction of sublingual with vaginal misoprostol for mid-trimester termination of pregnancy. The study was performed in the department of Obstetrics and Gynaecology, Jinnah Hospital, Lahore. One hundred patients presenting for termination of pregnancy between 13-24 wks of gestation were selected. They were divided into two groups, group I was managed with sublingual and group II with vaginal misoprostol. The dose of misoprostol was 200 pg repeated at intervals of 6 hours up to a maximum of four doses. The primary outcome measure was induction expulsion interval and secondary outcomes were maternal complications, and women's acceptance of the termination procedure. Successful termination was achieved in 96% patients in group I and 94% in group II. The patients in the two groups were comparable regarding their parity, gestational age and indications for termination. As regards the dosage, 76% in each group required a dose of 400 - 600 ug [P value 0.000]. Induction expulsion interval was < 12 hrs in 92% patients in group 1 and 88% in group II, a difference not statistically significant [P value > 0.005]. Pyrexia > 38°C was found in 8% and 6% in each group respectively while 8% in group I and 4% in group II had nausea and vomiting. So, sublingual misoprostol is as effective as vaginal misoprostol but with more nausea and vomiting, which can be managed easily. As a conclusion misoprostol can play a very important role in the practice of obstetrics and gynecology in resource poor countries where cost of other prostaglandins is prohibitively high and temperature maintenance is a problem. In proper dosage the risk of complications is low and most of the patients achieve completion of expulsion in less than 12 hrs by both routes
