目的 分析初产年龄对分娩方式及妊娠结局的影响,探讨最佳生育年龄。方法 对高龄初产妇(A组)及30～34岁(B组)、25～29岁(C组)的初产妇各121例进行分析。结果 高龄初产妇剖官产率为 57.02％,明显高于其余两组;难产因素在剖宫产适应症中所占比例,以B组最高,而年龄偏大是高龄组剖宫产的主要原因;阴道分娩病例中,B组产程最长;新生儿预后以C组最好。结论 应加强对30～34岁年龄段产妇的管理,尤其是分娩期的处理;25～29岁为最佳生育年龄。 Objective To analyze the effect of primiparous age on mode of delivery and pregnancy outcome and explore the optimal age of childbearing.
