Termination of Pregnancy in First Trimester - Medical Option.

BACKGROUND

The objective of this study was to confirm the effectiveness and safety of methotrexate and misoprostol or misoprostol alone for abortion up to 12 weeks of gestation.

METHODS

A group of volunteer patients desiring MTP with gestations up to 84 days (12 weeks) were studied. The patients were divided into 2 groups. Group 1 patients with gestation up to 56 days were further subdivided as (a) Patients who received methotrexate 50 mg IM + misoprostol 800 gms intravaginal and (b) patients who only received 800 gms of misoprostol. Group 2 included the patients who were 8-12 weeks pregnant and they received same treatment as group 1 (b). Outcome measures assessed included successful abortion (complete abortion without need for surgery), side effects, decrease in hemoglobin and mean duration of vaginal bleeding.

RESULTS

Complete abortion occurred in 36 (90%) of 40 patients in group 1 (a), 10 (67%) of 15 patients in group 1(b) and 29 (83%) of 35 patients in group 2. There were only 2 patients with clinically significant decrease in hemoglobin, but none required transfusions. Vaginal bleeding lasted 15 ± 6 days in group 1 (a), 16 ± 6 days in group 1(b) and 16 ± 5 days in group 2. All the patients stopped bleeding when endometrial thickness was < 5mm. Five percent women had stomatitis after methotrexate and 44% patients had fever with chills after misoprostol administration.

CONCLUSION

Considering the low cost and availability of methotrexate and misoprostol, these drugs constitute a good alternative for medical abortion. They are safe and effective.
