Clinical Analysis On Correlated Factors Of Extrauterine Growth Restriction In Very Low Birth Wight Infants

Objective:To Analysis the incidence of EUGR, and the factors that influencethe occurrence of EUGR and IUGR of316cases of very low birth weightinfants and the nutirtion in hospital, in order to reduce the occurrence ofEUGR and provide clinical basis.Methods:The clinical data of316very low birth weight infants that treated inThe First Hospital Bethune Jilin University from anuary in2007toDecember in2012were retrospectively analyzed. All cases are dividedinto IUGR group and non-IUGR group according to the birthweight,while the non-IUGR group is divided into EUGR group andnon-EUGR group according to the discharged weight. The main contentinciuded the basic information of the infants,complications,and thenutritional condition of the first and second weeks after birth.EXCELsoftware and SPSS19.0statistical software were used for statisticalanalysis.Result:1.316cases of very low birth weight infants in this research,including167cases of male,149cases of female.The incidence of IUGRat birth was32.6%(103cases) while the incidence of EUGR on dischargewas85.4%(270cases).All103cases of IGUR group developed intoEUGR,the incidence was100%.213cases of non-IGUR group had167 cases that developed into EUGR,the incidence was78.4%.2.The gestational age of IUGR group was higher than non-IUGRgroup while birth weight, discharged weight and length of hospitalizationwere less than that of non-IUGR group.The incidence of neonatalrespiratory distress syndrome and bronchopulmonary dysplasia innon-IUGR group is higher than that of IUGR group. Nutrient intakeshowed no significant difference between two groups.3.The birth weight,growth to body weight and the maximum energyintake after total enteral nutrition in EUGR group were lower than that ofnon-EUGR group while gestational age was higher than EUGRgroup.The mean daily protein,lipide mulsion and energy intake inpostnatal time of1week,2week in EUGR group were lower thannon-EUGR group.The logistic regression analysis show that gestationalage,birth weight and the mean daily protein intake in postnatal time of1week are Independent risk factors of EUGR.Conclusion：1.This study showed that the incidence of EUGR in very low birthweight infants was higher than the data reported in domestic andoverseas.2.The risk of EUGR in very low birth weight infants with IUGR washigher than those of non-IUGR.3.The relevant influencing factors of EUGR included Percentiles ofbirth weight, the protein,lipide mulsion and energy intake in postnataltime of1week and2week and the maximum energy intake after total enteral nutrition. Especially,the protein intake in postnatal time of1weekand Percentiles of birth weight are the independent hazards.
