■延长分娩时间是最常见的剖宫产指征,但是定义不一致,最近发现一些常见的定义高估了生理分娩的速度。这篇综述的目的是建立文献中用于长期劳动的同义词和定义的概述,分为第一和第二阶段,并建立使用的定义类型。
■在PubMed中进行了系统搜索,Embase,WebofScience,科克伦图书馆,Emcare,和学术搜索总理。
■所有(1)试图定义长期劳动的英文文章,(2)包括长期劳动的定义,或(3)包括任何长期劳动的同义词,包括在内。
■研究设计数据,出版年份,原产国家或地区,使用的同义词,延长的第一和/或第二阶段的定义,和来源提供的定义(如果不是主要由研究建立)被收集到数据库中。
■总共,筛选了3402篇摘要和536篇全文论文,包括232篇论文。我们的搜索为长期劳动建立了53个同义词。43项研究定义了长期劳动,189项研究采用了长期劳动的定义。延长第一产程的定义分为:基于时间的(n=14),基于进度(n=12),以临床医生为基础(n=5),或基于结果的(n=4)。对于定义延长第二阶段的33项研究,大多数定义(n=25)是基于时间的,根据呈现部分的总持续时间或不下降的持续时间。
■尽管努力达到统一的劳动曲线,长期劳动的定义仍然很少统一。需要就使用哪个定义达成共识,为了安全和尊重地允许生理劳动进展,确保及时管理,并评估和比较不同设置之间长期分娩的发生率。
UNASSIGNED: Prolonged labor is the commonest indication for intrapartum cesarean section, but definitions are inconsistent and some common definitions were recently found to overestimate the speed of physiological labor. The objective of this review is to establish an overview of synonyms and definitions used in the literature for prolonged labor, separated into first and second stages, and establish types of definitions used.
UNASSIGNED: A systematic search was conducted in PubMed, Embase, Web of Science, Cochrane Library, Emcare, and Academic Search Premier.
UNASSIGNED: All articles in English that (1) attempted to define prolonged labor, (2) included a
definition of prolonged labor, or (3) included any synonym for prolonged labor, were included.
UNASSIGNED: Data on study design, year of publication, country or region of origin, synonyms used,
definition of prolonged first and/or second stage, and origin of provided
definition (if not primarily established by the study) were collected into a database.
UNASSIGNED: In total, 3402 abstracts and 536 full-text papers were screened, and 232 papers were included. Our search established 53 synonyms for prolonged labor. Forty-three studies defined prolonged labor and 189 studies adopted a
definition of prolonged labor. Definitions for prolonged first stage of labor were categorized into: time-based (n=14), progress-based (n=12), clinician-based (n=5), or outcome-based (n=4). For the 33 studies defining prolonged second stage, the majority of definitions (n=25) were time-based, either based on total duration or duration of no descent of the presenting part.
UNASSIGNED: Despite efforts to arrive at uniform labor curves, there is still little uniformity in definitions of prolonged labor. Consensus on which
definition to use is called for, in order to safely and respectfully allow physiological labor progress, ensure timely management, and assess and compare incidence of prolonged labor between settings.
