Mid-second trimester medical terminations of pregnancy require admission to the hospital for the length of time it takes a woman to abort. The current protocol at BMC uses intra-amniotic digoxin injection the day prior to admission. The following day, the woman is admitted and given sequential doses of misoprostol until delivery occurs. The average length of time between the first dose of misoprostol and delivery is 12 hours, requiring most women to stay overnight. This is a randomized, placebo-controlled, double-blinded study designed to determine whether adding mifepristone significantly reduces the induction interval time (time between starting the first misoprostol and delivery) required for a second trimester termination.
