Conclusions:Almost half of puerperas with the length of second stage of labor longer than 2 h underwent vaginal delivery.The prolonged second stage of labor can decrease the score of Apgar scale in 1 min,increase the incidence of asphyxia,but has no effect on scale in 5 min.It still need more evidence from evidence medicine to definition of time and treatment of second stage of labor.展开更多
