Efficacy and safety of intrauterine device placement during a planned cesarean section
Abstract
Objective: Approximately 79% of pregnancies conceived within the first year after delivery are unintended and 50% of the couples report having unprotected intercourse before the first routine postpartum appointment. Unintended pregnancies are associated with unsafe abortions and other poor outcomes. We aimed to determine the efficacy and safety of intrauterine device (IUD) placement during a planned cesarean section (CS) at one year after insertion. Study Design: A survey-based retrospective cohort study conducted at a university teaching hospital. The study cohort included term pregnant women delivered by a planned CS between December 2016 and July 2020, and data collection and questionnaires were completed in July 2021. In the study group, copper or Levonorgestrel IUDs were placed through the uterine incision after delivery of the fetus and placenta, while women in the control group did not receive an IUD. Other perioperative managements were similar. The primary outcome was unintended pregnancy rate during the first year after delivery. Results: The study comprised a total of 150 women, with 50 and 100 in the study and control groups, respectively. None of the women in the study group became pregnant, compared with nine (9%) in the controls (p = 0.03), of them eight (88.9%) were unplanned. Perioperative outcome was comparable between groups. The rate of contraceptive use one year after delivery was significantly higher in the study group compared to the control group (86.0% vs. 35.0%, respectively, p < 0.001). Conclusion: IUD placement during CS is effective in preventing unintended pregnancies within the first year after delivery, with operative outcomes unaffected. Implications: Intrauterine device (IUD) placement during a planned cesarean section prevented unintended pregnancies within one year after birth. Additionally, the rate of contraceptive use at one year was significantly higher compared to women who elected not to have an IUD inserted during the cesarean. IUD placement did not affect perioperative outcomes.
