Postplacental intrauterine device (IUD) placement, defined as IUD placement within 10 min after delivery of the placenta, is an appealing strategy for increasing access to postpartum IUDs because it does not require a separate postpartum visit. These guidelines present an evidence-based assessment of postplacental IUD placement after vaginal and cesarean delivery. Postplacental IUD insertion is safe and does not have higher risks of complications than interval insertion. Most studies find that the risk of IUD expulsion is higher after postplacental insertion than after interval insertion for both vaginal and cesarean deliveries. Most studies find higher rates of expulsion after vaginal delivery than after cesarean delivery. However, expulsion rates vary widely across studies, without clear evidence about the factors that may influence expulsion. In settings where replacement of expelled IUDs is available, patient populations with low rates of return for the postpartum visit are most likely to benefit from provision of postplacental IUD placement with appropriate counseling about risks and benefits.
胎盘娩出后宫内节育器(IUD)放置,定义为在胎盘娩出后10分钟内放置IUD,是一种增加产后IUD获取途径的有吸引力的策略,因为它不需要单独的产后随访。本指南对阴道分娩和剖宫产术后胎盘娩出后IUD放置进行了基于证据的评估。胎盘娩出后IUD插入是安全的,与间隔插入相比并发症风险并不更高。大多数研究发现,无论是阴道分娩还是剖宫产,胎盘娩出后插入IUD的排出风险高于间隔插入。大多数研究发现阴道分娩后的排出率高于剖宫产。然而,不同研究的排出率差异很大,没有关于可能影响排出的因素的确切证据。在可以更换排出的IUD的情况下,产后随访复诊率低的患者群体最有可能从胎盘娩出后IUD放置及关于风险和益处的适当咨询中获益。
