ABSTRACT |
Objective |
: To assess the rates of success of the second dose of Misoprostol administration and to evaluate the parameters that affect the success of this approach.
Study Design |
: This retrospective cohort study was performed using institutional database of Carmel Medical Center between the dates of 1/11/2012-1/11/2017. Patients with ultrasound proven intrauterine abnormal pregnancy, treated for missed abortion or blighted ovum by two doses of intravaginal Misoprostol were included. The primary outcome was the treatment success rate of repeated Misoprostol treatment, and factors affecting this outcome.
Results |
: Overall, 97 patients were included in the study. The success of repeated dose of Misoprostol was noted in 46 cases (47.4%). A higher success rate was noted in symptomatic women - 64.3% vs. 35.7% in asymptomatic patients (Odds Ratio 2.6, 95% Confidence Interval 1.1-6.5). In addition, marginal significance was noted for pregnancies with an embryonic pulse previously observed (66.7% in the success group vs. 33.3% in failed treatment, p=0.051).
Discussion |
: Efficacy of a repeated Misoprostol course was shown to have a success rate of 47%%. This success rate is slightly increased in women presenting symptoms of bleeding before first administration. This information is highly important in the clinical discussion with each patient prior choosing a possible treatment.
