Comparison of four perioperative misoprostol regimens for surgical termination of first-trimester pregnancy
Abstract
Objective
To compare the outcomes of 4 different perioperative misoprostol regimens for surgical termination of first-trimester pregnancy.
Methods
Retrospective analysis of the records of 4000 women (4 cohorts of 1000 each) who underwent surgical termination of pregnancy. The 4 cohorts received: no misoprostol; 200
μg of oral misoprostol 30 minutes preoperatively; 200
μg of sublingual misoprostol 30 minutes preoperatively; or 200
μg of oral misoprostol 3 hours preoperatively plus 200
μg of vaginal misoprostol postoperatively. Adverse effects of the last regimen were surveyed in 1000 women.
Results
In the cohorts that received misoprostol, the difficulty of cervical dilatation was reduced (P
<
0.001) compared with the cohort of women that did not receive misoprostol. The frequency with which women made postoperative contacts with the clinic was also reduced in the cohorts that received misoprostol (P
<
0.05). Adverse effects were minimal.
Conclusions
This retrospective study showed an association between perioperative administration of misoprostol, reduced difficulty for operators, and reduced demand for postoperative care. The regimen associated with the greatest reduction in difficult cervical dilatations and postoperative consultations was 200
μg of oral misoprostol 3 hours preoperatively plus 200
μg of misoprostol vaginally at the end of the surgical procedure.
