Immediate postpartum placement of intrauterine devices (IUDs) can help reduce unintended short-interval pregnancy; however, the rate of spontaneous device expulsion is increased. The objective of this study is to evaluate the risk of expulsion with ultrasound-guided placement of immediate postpartum IUDs. Retrospective review of all patients receiving immediate postpartum IUDs after vaginal delivery at Prisma Health Richland Hospital from 2018 to 2020 was performed. Outcomes were available for 78 patients in the ultrasound-guided cohort and for 226 in the control cohort. The expulsion rate was 15.4% (95% CI 8.2-25.3%) for the ultrasound-guided cohort and 14.2% (95% CI 9.9-19.4%) for the control cohort. Our data suggest that using ultrasonography to guide placement of IUDs immediately after vaginal delivery is not associated with the risk of expulsion.

超声引导与非超声引导下即刻产后宫内节育器放置的比较。

产后立即放置宫内节育器 (IUD) 有助于减少意外的短间隔妊娠；然而，自发设备排出率增加。本研究的目的是评估超声引导下立即放置产后宫内节育器的排出风险。对 2018 年至 2020 年在 Prisma Health Richland 医院阴道分娩后立即接受产后宫内节育器的所有患者进行了回顾性研究。结果可用于超声引导队列中的 78 名患者和对照组中的 226 名患者。超声引导队列的排出率为 15.4% (95% CI 8.2-25.3%)，对照组的排出率为 14.2% (95% CI 9.9-19.4%)。
