Abstract: Objective：To evaluate the effectiveness of the immediate implementation of contraceptives after repeated abortion. Methods: With informed consent, contraceptives were implemented in 1 251 cases of repeated abortion during or after the post-abortion care (PAC) service. The clinical application and side effects of contraceptives were followed up.  Results: All of those women who received the PAC service after repeated abortion adopted the immediate contraceptives on their own. The rate of sustaining usage in the combined oral contraceptives (COC) group was 31.2% after 12 months of follow-up visit. Only three women in the intrauterine system (IUS) group removed the devices after 12 months of follow-up visit due to the fertility requirement. There were 19, 13 and 17 women who changed from COC to IUS after 3, 6 and 12 months of follow-up visit. Analogously, there were 6 women who removed intrauterine device (IUD), and one who had ectopic pregnancy in the IUD group. There were 23, 31 and 19 women who changed from COC to IUD after 3, 6 and 12 months of follow-up visit. During the whole follow-up visit, some adverse reactions, such as irregular vaginal bleeding, amenorrhea, hypomenorrhea, hypermenorrhea, the ring moved-down and waist soreness and discomfort, were effectively treated. Conclusions: Scientific and effective PAC can effectively avoid repeated abortion and protect female reproductive health.
