Objectives: Research on the treatment of second-trimester miscarriages is scarce. We studied the outcomes, and the factors associated with adverse events and need for hospital resources in the medical treatment of second-trimester miscarriage.
Materials and methods: In these retrospective analyses we studied women treated for spontaneous fetal miscarriage with misoprostol-only (n = 24) or mifepristone and misoprostol (n = 177) in duration of gestation 12+1–21+6. Primary outcomes were the risk factors for surgical evacuation and excessive bleeding. Secondary outcomes were total misoprostol dose, time to expulsion and the length of hospital stay.
Results: History of surgical evacuation of the uterus increased the risk of surgical evacuation (p = 0.027). Excessive bleeding was not associated with any of the studied variables. More misoprostol was needed when the duration of gestation exceeded 17+0 weeks (p = 0.036). In multivariate analysis the time to fetal expulsion was shorter in women with history of 1–2 deliveries (hazard ratio [HR] 1.49, 95% confidence interval [CI]; 1.07–2.07), ≥3 deliveries (HR 1.63, 95% CI; 1.11–2.38) and with a two-day interval between mifepristone-misoprostol administration (HR 1.71, 95% CI; 1.05–2.81). Patients with symptoms (i.e. uterine bleeding or pain) at baseline had longer hospital stay (HR 0.66, 95% CI; 0.47–0.92).
Conclusions The factors affecting the outcomes of medical treatment of second-trimester fetal miscarriage are similar to those of second-trimester induced abortion. Two-day interval between mifepristone-misoprostol administration might decrease the time to fetal expulsion and the need of hospital resources.
