Abstract
Objective To explore the effect of labor treatment guided by the new labor standard(proposed by ZHANG and others in 2010) on the delivery outcome.Methods This study was carried out between two sample groups,the study group(709 primiparas who received labor treatment guided by the new labor standard in the Third Affiliated Hospital,Sun Yat-sen University between January and August 2015),and the control group〔819 primiparas who received labor treatment guided by the traditional labor standard(developed by FRIEDMAN in the 1950s) in the same hospital between January and August 2014〕.We compared the delivery mode,postpartum hemorrhage rate,incidence of adverse neonatal outcomes(abnormal Apgar score,percentage of neonates with umbilical cord blood pH value<7.0,incidence of meconium stained amniotic fluid),and duration of labor between the two groups.And we observed the delivery outcome of the primiparas in the study group who were diagnosed with abnormal labor curve by the traditional labor standard but treated with the new labor standard during labor.Results Compared with the control group,the study group had higher spontaneous labor rate,and lower cesarean section rate(P<0.01).No significant differences were found between the groups in the postpartum hemorrhage rate,proportion of neonates with low 1-min Apgar scores,percentage of neonates with umbilical cord blood pH value <7.0 and incidence of meconium stained amniotic fluid(P>0.05);two groups of 5-min Apgar scores were not abnormal.The study group had longer first stage of labor,second stage of labor,and overall duration of labor than the control group(P<0.05).The spontaneous labor rate of three kinds of primiparas in the study group who were diagnosed with prolonged latent phase of labor(>16 h),prolonged active stage of labor(>8 h) and prolonged second stage of labor(>2 h) by the traditional labor standard but treated with the new labor standard during labor was 45.8%(11/24),69.2%(9/13),84.1%(37/44),respectively.Conclusion Treatment for labor with the new labor standard,could reduce the cesarean delivery rate and promote the natural childbirth without increasing the risks of postpartum hemorrhage,forceps delivery and adverse neonatal outcomes.关键词
