Different Methods for Termination of Mid-trimester Pregnancy With Placenta Previa 


 Objective: Investigate the different methods for termination at mid-trimester in pregnant women with placenta previa. Methods: A retrospective study was conducted on 264 cases for termination at mid-pregnancy in our hospital, and 34 cases with placenta previa were set as the observation group, and 230 cases with normal placenta were set as control group. Among them, the preferred methods of termination at first were Mifepristone combined with Misoprostol/Rivanol in the observation group, and Mifepristone combined with Misoprostol/Rivanol/cervical double balloon (CDB) in the control group. If the volume of prenatal bleeding was up to 100 mL in the observation group, emergency artery embolization (UAE) was implemented to stop bleeding, then CDB plus with curettage were used in order. If it failed to induce in the control group, CDB was used subsequently followed with Misoprostol/Rivanol. Then, all those cases were set as the comprehensive-induce group, and the others were set as the simple-induce group.Results: the average maternal age, the number of gravidity/parities, the rate of cesarean section, the hospitalization days and cost, the induction time, the rate of postpartum hemorrhage, puerperal infection were higher in the observation group than those in the control group(p<0.05). There were 4 cases used UAE+CDB+curettage in the observation group and 6 cases used CDB after Misoprostol/Rivanol in the control group. The duration time of termination, the rate of postpartum hemorrhage and transferring to ICU, hospitalization days and cost in the comprehensive-induce group were significantly higher than those in the simple-induce group (p<0.05). All cases were delivered through vaginal successfully.Conclusion: We should pay more attention to the complications of prenatal bleeding, postpartum hemorrhage, puerperal infection during the induction at mid-trimester in pregnant women with placenta previa. Emergency UAE + CDB +curettage is a good combination method in prenatal hemorrhage of placenta previa during termination, and CDB was a good tool for cervical ripen with immature cervical condition in mid-trimester for induction of labor.
