Abstract: Objective:Summary of our hospital in the past 15 years the increasing cesarean section rate,discusses how to reduce the rate of cesarean section,to improve the quality of obstetric method.Methods:Retrospective analysis of our hospital from 1995January to2009December,9478 cases of pregnant women with clinical data,focuses on the analysis of neonatal birth weight,neonatal asphyxia,neonatal mortality and rate of cesarean section and its relation to.Results:The cesarean section rate increasing,increasing from 19.21% in 1995 to44.19% in 2009,the difference was statistically significant(χ2=82.87,P<0.01).The average weight of newborn babies15 years remained stable at around 3 500g.The great children(WT>4 000g) in neonates in the proportion of stable at around 18%,but huge cesarean section rate but by 26.47% 19952009 soared to69.14%,the difference was statistically significant(χ2=27.26,P<0.01).with the increasing cesarean section rate,neonatal asphyxia rate reduced from 3.84% to 3.70,the difference was statistically significant(χ2=104.3,P<0.01).Conclusion:The neonatal birth weight high,prompting nutrition of pregnant women is in excess of15 years has been the problems,good nutrition during pregnancy,reduce the average neonatal birth weight,is expected to reduce the rate of cesarean section.The great children’s cesarean section rate rise quickly in a certain extent reduce the rate of cesarean section is feasible.The average neonatal body weight on the 3 500g level,the rate of cesarean section in 40% the left and right sides can obtain better maternal and fetal outcome.
