Objective: To evaluate of the effectiveness of low-dose (LD) vaginal
misoprostol administration, where dose adjustment was made by taking
into account the gestational week and cesarean section (C/S) history in
termination of pregnacy (ToP). Design: Retrospective observational
cohort study. Setting: A single tertiary center Population: 563 patients
who opted ToP under 34 weeks of gestation. Methods: Outcomes were
ascertained by health record review and compared between subgroups
according to gestational weeks and previous C/S history. Main Outcome
Measures: Total misoprostol administration time, total labor time, total
misoprostol dose, >1 ToP method, uterin rupture, uterine
atony Results: 63% (357) of 563 cases with pregnancy termination were
below the 24th gestational week (Gx). The remaining 206 cases (Gy)
(37%) were between 24 and 34 weeks of gestation. The rate of C/S
history was statistically significantly higher in Gx (p=0.030). While a
single termination method below 24 weeks was sufficient in 94% of
cases, this rate remained at 86% in Gy (p=0.002). There was no
difference in the complication rate between the groups according to the
gestational week or the presence of a prior C/S (p>0.05).
Concusions: The present regimen is an effective method with low maternal
morbidity and high success without increasing the total treatment time.
Especially in patients with a history of C/S where the ‘experience of
ToP with misoprostol’ have relatively high risk , and in all ToPs below
34 weeks, achieving a high birth rate without increasing the uterine
rupture rate suggests that it is a safe approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
