围产期胎儿和新生儿死亡的风险很高，幸存者也有可能出现终生并发症。有围产风险的家庭应获得有关胎儿、新生儿和孕产妇风险以及分娩或继续妊娠结局的客观、准确和最新的信息。本文描述了接近生存极限的分娩的各种描述性术语，考虑了生存极限随时间的变化，并强调了在短暂妊娠延长和/或围产期内改变临床情况时调整咨询的重要性。
Periviable birth carries a high risk of fetal and newborn death, and the potential for life-long complications in survivors. The family at risk for periviable birth should receive objective, accurate, and up to date information regarding fetal, newborn, and maternal risks and outcomes with delivery or with continued pregnancy. This article describes the various descriptive terms for delivery near the limit of viability, considers the evolving limit of viability over time, and highlights the importance of adjusted counseling with brief pregnancy prolongation and/or changing clinical circumstances within the periviable period.
