早产是新生儿死亡的主要原因，也是产前住院治疗的最常见原因。在美国，大约12%的活产发生在足月之前，而在这些早产中，大约有50%发生在早产之前。虽然早产的原因尚不清楚，但早产的负担是明确的，约70%的新生儿死亡和36%的婴儿死亡以及25-50%的儿童长期神经损伤病例都是由早产造成的。美国医学研究所（Institute of Medicine） 2006年的一份报告估计，美国每年因早产造成的损失为262亿美元，或者说每个早产儿造成的损失超过5.1万美元。然而，确定女性是否会早产是一个不准确的过程。本文件的目的是提出各种方法提出管理早产，并审查这些方法在临床实践中的作用的证据。早产危险因素的识别和管理在本文件中没有提及。
Preterm birth is the leading cause of neonatal mortality and the most common reason for antenatal hospitalization . In the United States, approximately 12% of all live births occur before term, and preterm labor preceded approximately 50% of these preterm births . Although the causes of preterm labor are not well understood, the burden of preterm births is clear-preterm births account for approximately 70% of neonatal deaths and 36% of infant deaths as well as 25-50% of cases of long-term neurologic impairment in children . A 2006 report from the Institute of Medicine estimated the annual cost of preterm birth in the United States to be $26.2 billion or more than $51,000 per premature infant . However, identifying women who will give birth preterm is an inexact process. The purpose of this document is to present the various methods proposed to manage preterm labor and to review the evidence for the roles of these methods in clinical practice. Identification and management of risk factors for preterm labor are not addressed in this document.
