Abstract：Objective To investigate the contraceptive effect and safety of two methods of placing intrauterine device and oral contraceptives after induced abortion. Methods A total of 116 patients with induced abortion who were admitted to the Department of Obstetrics and Gynecology of Xishan People′s Hospital in Wuxi City from September 2019 to September 2021 were selected as the research objects, and divided into the experimental group (51 cases) and the control group (65 cases) according to the patients′ wishes. The levonorgestrel-releasing intrauterine system (Mirena) was placed in the experimental group after operation, and the oral contraceptive was used in the control group. The intervention effects of the two groups were compared. Results There was no significant difference in the rate of contraceptive failure between the two groups (P>0.05). The duration of postoperative bleeding in the experimental group was lower than that in the control group, and the difference was statistically significant (P<0.05). The correct usage rate of experimental group was higher than that of control group, and the difference was statistically significant (P<0.05). The total incidence of adverse reactions in experimental group was lower than that in control group, and the difference was statistically significant (P<0.05). Conclusion After artificial abortion, both Mirena and oral contraceptives can achieve the ideal contraceptive effect, but the safety of Mirena is relatively high, worthy of clinical reference.
