Termination of early pregnancy in the scarred uterus with mifepristone and misoprostol.

OBJECTIVE

To analyze the safety and possibility of terminating early pregnancy up to 49 days gestation after cesarean section with mifepristone and misoprostol.

METHODS

One-hundred and ninety-two early pregnant women were recruited, of which, 35 cases with uterine cicatrix and 157 cases were no-uterine cicatrix as control group. All of them took 25 mg of mifepristone, b.i.d. for 3 days and 600 microg of misoprostol on the 4th day.

RESULTS

Of the 35 cases with uterine cicatrix, 33 achieved complete abortion after medical abortion. The complete abortion rate was 94.29% (95% CI 81-99%) in the cicatrix group and 89.81% (95% CI 75-91%) in the control group. There were no obvious complications detected in the cicatrix group.

CONCLUSION

For the termination of early pregnancy in scarred uterus, administration of mifepristone and misoprostol is safe and effective, and a further large series study needs be done to confirm its acceptability as a routine medication in such situations.
