[Good results of early medicinal pregnancy termination in a general practice on Curaçao]

To evaluate the results of early medicinal pregnancy termination.

Prospective, non-blinded, clinical study.

Between 2001 and 2005, 371 women presented to a medium-sized solo general practice in the centre of Willemstad, Curaçao, to request termination of an undesired pregnancy. Ofthese women, 74 first indicated a preference for abortion via curettage, and the remaining 297 chose to be treated medicinally. In the first trimester of the pregnancy, they were given methotrexate i.m. and misoprostol vaginally 3-5 days later, or only misoprostol vaginally when methotrexate was unavailable. The result was evaluated by abdominal echography two days after the treatment.

The result of the medicinal pregnancy termination could be determined in 271 of the 297 women. In 219 (81%) of these, the pregnancy had been terminated after a single treatment, and in 29 (11%) success was achieved after a second vaginal administration of misoprostol. The total success rate of the medicinal pregnancy termination was 92% (248/271). Curettage was required in 23 women (8%) after the medicinal treatment had failed. There was no significant difference in success rate between treatment with the methotrexate-misoprostol combination and treatment with misoprostol alone.

Medicinal pregnancy termination with methotrexate and misoprostol, or with misoprostol alone, was a safe method with a relatively small risk of an ongoing pregnancy. It was a good alternative for surgical abortion.
