Objective : To evaluate the efficacy and the adverse effects of misoprostal usage for thera peutic abortion in Siriraj Hospital. Study
Design : Cross-sectional, descriptive study.
Materials and Methods : A consecutive series of 101 therapeutic abortions was performed in the Department of Obstetrics & Gynecology, Siriraj Hospital in the year 2000. The patients were interviewed for general information and registered, as well as in-patient data. Any adverse events were recorded and collected from the inpatient record file. All data were analyzed statistically.
Results : 42 therapeutic abortions were conducted in association with misoprostal usage. Misoprostal was used for cervical ripening in 8 patients with a good outcome. 31 therapeutic abor tions were induced by misoprostal alone regimen. A higher success rate (74.1%) was correlated with higher gestational age. 27 out of 31 cases were second trimester abortion. The induction to abortion interval was 18.0±10.5 hours (range 5-48). No factor, including age, weight, total dose of miso prostal use, nulliparity and viability of the fetus, could be demonstrated to affect the misoprostal activity defined by induction to abortion interval. There was no serious adverse event, except for severe abdominal cramping (26.2%) and fever (14.3%).
Conclusion : Misoprostal alone can be used with caution for abortion induction especially in second trimester abortion.
