Resumo: BACKGROUND: Termination of pregnancy requires a 48-hour 'window' between mifepristone and misoprostol. Shorter durations have been used in first-trimester termination, but there are few data available in later termination for fetal anomaly. MATERIAL AND METHODS: We reviewed all terminations for fetal anomaly at ≥13 weeks from May 2013 to May 2014. Cases were managed using a short (≤12 h) or standard (≥36 h) mifepristone-to-misoprostol interval. RESULTS: Two hundred and twenty women underwent a termination of pregnancy for fetal anomaly during the study period, of which 119 were included for analysis. Sixty-six (55%) women were managed according to the short regimen and 53 (45%) women with the standard regimen. The short regimen resulted in a shorter mifepristone-to-delivery interval but was less likely to result in delivery within 12 h of misoprostol. Delivery rates at 24 h were equivocal. There was no difference in blood loss, vaginal delivery rates, complications or bed nights. The short regimen did require more doses of misoprostol. Feticide or previous uterine scar had no effect on outcomes. DISCUSSION: There was no significant difference in clinical outcome for women managed with a short (≤12 h) or a standard (≥36 h) regimen for medical termination of pregnancy for fetal anomaly, suggesting that either regimen could be offered.
