Objectives: To evaluate the efficacy, safety and influence on subsequent fertility of sulprostone, a prostaglandin E 2 analog, in terminating pathological pregnancies via the extraamniotic route. Methods: Forty pregnant women with intrauterine fetal death or major congenital anomalies were enrolled. Sulprostone was instilled into the extraamniotic space through a silicon Foley catheter. The instillation rate was 0.5–1 μg/min. Instillation was discontinued when the catheter was expelled or when rupture of the membranes occurred. The duration of instillation and the time interval to completion of abortion was recorded. Information about subsequent fertility was collected by telephone or at outpatient clinic visits. Results: The mean duration of instillation was 7.0 h and the mean dose of sulprostone was 314.8 μg. The mean induction‐to‐abortion interval (IAI) was 17.0 h. In two of the 40 patients, the cervix was not adequately ripened after 48 h and these pregnancies were ultimately terminated by alternative methods. The success rate of termination in 48 h was 92.5% (37/40). No severe side effects were encountered. Conclusion: To the best of our knowledge, this is the first report in the English literature of administration of sulprostone by extraamniotic instillation for termination of pathological pregnancies. The method is effective and safe and has an insignificant influence on subsequent fertility.
