摘　　要：目的探讨第二产程时限对新生儿预后的影响。方法将216例单胎、足月、无阴道分娩禁忌证的初产妇按照第二产程持续时间(t)分为4组,比较4组间新生儿结局情况。结果手术产率、脐动脉酸血症发生率及新生儿转入新生儿加强监护病房(NICU)的发生率在t>90 m in组明显高于t≤30m in组、30<t≥60 m in组及60<t≤90 m in组(χ2=15.607,25.029,16.892;P=0.003,0.000,0.005);新生儿窒息率在4组间无明显差别(χ2=2.825,P=0.419)。结论第二产程持续时间>90 m in,新生儿不良结局发生率增加,故应重视和积极处理第二产程。Objective To investigate the effect of the duration of the second stage of labor on neonatal prognosis. Methods 216 primiparas with singleton pregnancy and term labor without contraindications for vaginal delivery were divided into four groups according to the duration of the second stage of labor（t）. Neonatal outcomes were compared among the four groups. Results Parturients with t 〉 90rain had significantly higher rates of operative delivery, umbilical arterial acidemia and NICU admissions than those with t≤30min, 30〈t≤ 60min and 60〈t≤90min（Χ^2 = 15. 607, 25. 029, 16. 892; P =0. 003, 0. 000, 0. 005, respectively）. There were no significant differences in incidences of neonatal asphyxia among the four groups （Χ^2 =2. 825, P =0. 419）. Conclusion The incidences of adverse neonatal outcomes increases significantly when the second stage of labor lasts more than 90 minutes.
