Variance of Perinatal Asphyxia in Latest 10 Years and Analysis of Mortality and Risk Factors of Perinatal Asphyxia / 实用儿科临床杂志

ABSTRACT

Objective To analyze the incidence rate and mortality of perinatal asphyxia and effects of new resuscitation technique on asphyxia as well as the risk factors of asphyxia in latest 10 years.Methods A retrospective evaluation was done for all the newborns who were born in the provincial women and children′s health care hospital from 1995 to 2004.The morbidity,mortality and fatality rate were calculated for each observed year and different seasons.The influence of gender,body weight,gestational age as well as polyembryony and mode of delivery on the asphyxia was analyzed.Results The morbidity of mild birth asphyxia was decreased dramatically and maintained at about 1.5% after using new resuscitation technique,however,there were no obvious effects on the sever asphyxia.In the same time,no big influence on fatality rate of birth asphyxia was observed.The incidence rate was highest in April,but the mortality and fatality of asphyxia was highest in July.The incidence of asphyxia was also related with gender,polyembryony,birth weight,prematurity babies and aids to delivery from voginal.Conclusions The incidence of perinatal asphyxia is related with the gender,polyembryony,birth weight and gestation age as well as seasons.New resuscitation technique can reduce the morbidity of mild birth asphyxia,and no effect on the severe asphyxia as well as fatality rate.
