Background: Medical termination of missed miscarriage and incomplete miscarriage with misoprostol, are an alternative to surgical evacuation (dilatation and curettage). This study aimed to evaluate the effectiveness of misoprostol in highly parous woman for incomplete and missed miscarriage.

Methods: This was a retrospective study was conducted in two different time lines (2010 and 2014). All patients admitted to the Sultan Qaboos University hospital, Muscat, Oman, for the management of first-trimester miscarriages (missed and incomplete types) during the study period were included. Some women were moved to dilation and curettage even after misoprostol. The effect of gravidity and parity on those women in whom misoprostol was not effective was studied.

Results: The overall success rate of misoprostol for the management was 62.14% in 2010 and 53.8% 2014. In nulliparous woman the success rate of misoprostol was slightly higher than parous women. There was no apparent effect of gravidity and parity of ≥ 5 or ≥ 5 on the success of misoprostol.

Conclusions: Misoprostol reduced the rate of surgical evacuation among the study subjects. In highly parous and multigravid women (≥ para 5 and gravida ≥5) the success was not significantly different compared to less parous women.
