A Comparative Study of Misoprostol Only and Mifepristone Plus Misoprostol in Second Trimester Termination of
1Kamineni Academy of Medical Sciences and Research Center, Hyderabad, Telangana India.
Objective:
To compare the effectiveness, success rate and induction to abortion interval between administration of misoprostol only and mifepristone with misoprostol in second trimester abortions (14-20 weeks) .
Materials And Methods:
The study was conducted by dividing women approaching for second trimester termination, into two groups each consisting of 100 women. Group-I received only misoprostol; 600 mcg initial vaginal insertion followed by 400 mcg sublingually every 3 h until termination. Women in Group-II received mifepristone 200 mg and after 24 h started with 600 mcg misoprostol, per vaginal followed by 400 mcg sublingually till abortion was completed, up to a maximum of five doses in both groups.
Results:
The success rate in Group-I was 89 %, whereas in Group-II it was 96 %. The mean induction abortion interval in Group-I was 10.67 ± 3.96 h compared to Group-II which was significantly less 6.19 ± 2.70 h (p value < 0.01). The mean dose of misoprostol in Group-I was 1610 ± 511.18 mcg and in Group-II, it was lesser 1046 ± 392.71 mcg (p value < 0.01). There was significant difference in the mean blood loss also, 97.20 ± 36.35 ml in Group-I and 52.55 ± 27.96 ml in Group-II. Also among the individual groups multigravidae and lower gestational age (<17 weeks), women had lesser IAI as well as lesser misoprostol dose was required.
Conclusion:
Pretreatment with mifepristone significantly reduces the induction abortion interval and the misoprostol dose along with minimal blood loss.
