In summary, late preterm birth results from spontaneous, indicated, and sometime elective indications. The burden of prematurity can be decreased if elective late preterm delivery is eliminated. While recent recommendations from the NICHD/SMFM workshop on timing of late preterm and early term birth have helped to guide management, the authors acknowledge that most of their guidelines are based on grade B or C evidence. Certain conditions absolutely warrant late preterm delivery; however, the clinician should weigh the risks of iatrogenic prematurity with the benefits of delivery for maternal or fetal indication when considering intervention for this cohort.
总之，晚期早产儿的分娩原因包括自发性、指征性和有时的选择性指征。如果消除选择性晚期早产儿分娩，早产儿的负担可以减轻。虽然最近 NICHD/SMFM 关于晚期早产儿和早期足月产时机的研讨会的建议有助于指导管理，但作者承认他们的大多数指南都是基于 B 级或 C 级证据。某些情况绝对需要晚期早产儿分娩；然而，当考虑对这一组进行干预时，临床医生应权衡医源性早产的风险与母亲或胎儿指征分娩的益处。
