Methods Five hundred and fifty women with long-term contraceptives without contraindication for IUD were selected and randomly divided into two groups (250 in each group). Observation group placed INIUD, control group placed Tcu220C. Results During the first trimester of abortion, no uterine perforation was found in the IUD, no infection was found, and no hemorrhage occurred after placement. The pregnancy rate, abortion rate and the incidence of pain were lower in the observation group than those in the control group. Conclusion It is safe and feasible to place IUD in early pregnancy induced abortion, and INIUD has few side effects.
