RESUMO
Objective: To compare the outcome of two regimes of mifepristone and misoprostol (oral vs vaginal and sublingual administration of misoprostol) for medical termination of early pregnancy (within 49 days). Study design: A randomized controlled study was conducted. On 75 women undergoing medical termination of pregnancy (MTP) within 49 days of amenorrhea (7 weeks). These women were divided into two groups – Group 1: received tablet mifepristone 200 mg orally followed by tablet misoprostol 600 mcg oral after 48 h. Group 2: received tablet Mifepristone 200 mg orally followed by misoprostol tablet 800 mcg, two tablets administered per vaginum and two tablets advised to be taken sublingually after 12 h. An ultrasonography pelvis was performed on all patients pre-MTP to confirm the location and age of gestation and post-MTP on day 15 to confirm no retained products of conception. Statistical analysis was done by two proportion tests for individual side effect with the null hypothesis. Results: The complete abortion rates in Group 1 were 91.4% as compared to 90% in Group 2. Only 11.4% of women in Group 1 and 12.5% in Group 2 had bleeding for more than 15 days. The duration and amount of bleeding were statistically similar in both groups. Conclusion: We concluded that after 48 h of administration of mifepristone, oral 600 mcg of misoprostol is as efficient as 800 mcg of misoprostol (administered vaginally, 400 mcg and sublingually, 400 mcg) in inducing medical abortion of pregnancy within 49 days of amenorrhea.
