Background

Cervical priming agents mainly prostaglandins in different doses and routes are used during first trimester vaccum aspiration to prevent cervical injury and shorten the abortion procedure. This study was carried out to assess women‘s acceptability, the efficacy and side effects of oral versus vaginal administration of misoprostol in facilitating cervical dilatation prior to first trimester vaccum aspiration.

Methods

A randomised control study where 120 women were divided in oral (51) and vaginal (69) group. Each group received 400 mcg of misoprostol either orally or vaginally 04 h prior to first trimester pregnancy termination. Baseline cervical dilatation, women‘s acceptability and side effects and complications were noted in both the groups.

Results

There was no difference between the oral and vaginal misoprostol groups with respect to mean cervical dilatation (5.53 mm vs 5.43 mm; p > 0.05). A total of 88% of women in the oral group expressed satisfaction with the route of misoprostol administration as compared to 74% in the vaginal route. The women in the vaginal group were experienced more preoperative vaginal bleeding (43% vs 25%).

Conclusion

Oral administration of misoprostol is an effective alternative to vaginal administration in preinduction cervical ripening prior to first trimester pregnancy termination.
