目的:了解产妇分娩时滞产的原因。方法:选择2004年10月~2006年10月,在该院分娩的总产程延长的单胎头位初产妇124例为观察组,同期住院分娩的单胎头位产程正常的124例初产妇为对照组,观察两组产妇第一、第二产程时间,胎方位及分娩方式,新生儿出生体重、产力、母婴并发症及精神心理因素对产程的影响。结果:观察组潜伏期>16 h,活跃期>8 h,第二产程>2 h,阴道助产,剖宫产率,母婴并发症多于对照组(均P<0.05)且产力异常,精神心理因素观察组高于对照组(P<0.05)。结论:滞产与第二产程关系不大,而与第一产程、潜伏期延长,胎方位异常导致活跃期延长、产力、精神心理因素及分娩环境密切相关,易引起母婴并发症,阴道助产,剖宫产率升高,应及早发现,主动干预及时处理。 Objective: To understand the causes of labor delay labor.
