| Objectives1.To analyze the different effects of standardized management and non-standardized management on physical development and nervous system development of preterm infants after discharge from the hospital;2.To evaluate the effect of standardized feeding management;3.To provide a reference for promoting the growth and development of premature infants.Methods Preterm infants who underwent a physical examination in the Department of Child Health,North Hospital of Chenzhou Hospital,Nanhua University from June 2016 to February 2019 were taken as the research object.All infants were divided into standardized feeding group and non-standardized feeding group according to the follow-up and feeding instructions from the "Feeding Recommendations for Preterm/Low Birth Weight Infants Post-Discharge Feeding",which was published on the Chinese Journal of Pediatrics in 2016.Body weight,height,and head circumference of infants at 40 weeks after gestation,6 months and 12 months of age(corrected)were collected;WHO Anthro software(version 3.2.2)was used to calculate the weight Z(WAZ).Length Z(LAZ),head circumference Z(HCZ)for age,weight Z(WLZ)for length.Neuropsychological developmentStandards for Children 0-6 years old(version,2005)was used to assess neurological development.Then developmental quotient of 6 months and 12months(corrected)were selected.The WAZ,LAZ,HCZ,WLZ,and development quotient of the two groups were processed statistically;the index Z of physical development,distribution of development quotient,and changes in the characteristics of premature infants were analyzed,and the differences in growth and development between the two groups were compared.Results1.WAZ,LAZ,and HCZ of standardized feeding group and non-standardized feeding group at 6 months and 12 months of age,and40 weeks gestational age(corrected)showed no statistical significance(P> 0.05).WAZ,LAZ,and HCZ of the standardized feeding group at 6and 12 months were higher than those in the non-standard feeding group with statistically significances(P<0.05).The WAZ,LAZ,and HCZ in the non-standardized feeding group showed an upward tendency,and the growth rate from the gestational age of 40 weeks to the corrected 6-month age was faster than that from the corrected 6-month to the corrected12-month age.2.The standardized WLZ at corrected gestational age of 40 weeks,corrected 6-month-old and corrected 12-month-old WLZ was more than 0;the WLZ difference of corrected gestational age of 40 weeks and corrected 6-month-old between standardized feeding group and unstandardized feeding group showed no statistical significance(P>0.05).The 12-month-old WLZ of the non-standardized feeding group was higher than which of the standardized feeding group with statistically significance(P<0.05).The WLZ in both groups showed an upward tendency.The growth rate from age 40 weeks to 6 months of correction was faster than that from correction 6 months to 12 months of age.The increase rate of non-standard feeding correction from 6 months to 12 months was faster than which of the correction of gestational age 40 weeks to 6 months of correction.3.There was no statistically significance between the standardized feeding group and the non-standardized feeding group in low body weight rate,growth retardation rate,wasting rate,and overweight rate(P> 0.05)in correcting the gestational age of 40 weeks;the low body weight,growth retardation rate,and wasting rate in standardized feeding group corrected 6-month-old were lower than those in the standardized feeding group with statistically significance(P<0.05);the low body weight rate,growth retardation rate,and overweight rate in standardized feeding group corrected the 12-month-old were lower than the non-standardized feeding group with statistically significance(P<0.05).4.The developmental quotient of the standardized feeding management group at 6 and 12 months of age was higher than that of the non-standardized feeding management group,and the difference was statistically significant(P<0.05).All were higher than the corrected6-month age,and the difference was statistically significant(P<0.05).5.The quotient deviation rate of the standardized feeding management group at corrected 6 and 12 months of age was lower than that of the non-standardized feeding management group,and the difference was statistically significant(P<0.05).Conclusions1.The physical development and nervous system development of premature infants after discharge from hospital with standardized feeding are better than that with non-standard feeding.2.The promotion and implementation of standardized feeding have important practical significance for the growth and development of premature babies. |
