Correlation Analysis Of The Preterm Infant Respiratory Distress Syndrome And Serum Concentration Of Vitamin A

Objective:To study the relationship between the level of serum vitamin A(VA)status and prevalence rate of RDS on preterm infants. Then discuss different level of VA and the degree of RDS. Method:The 230 preterm infant data are collected from May 2014 to May 2015 of our hospital, According to the results of chest X-ray, this paper divided 115 RDS infants into two groups, the infants with RDS of degree I and II are in the mild group, and degree III and IV are in the severe group.This paper divided the RDS infants into three groups according to the fetal age, then made a comparison study of the three groups. this paper detected the level of serum vitamin A on the subject, and grouped the infants into RDS and non-RDS group, then compare the relationship between level of serum vitamin A(VA)status and prevalence rate of RDS on preterm infants. Results:According to the results of chest X-ray, this paper divided 115 RDS infants into two groups, the infants with RDS of degree I and II are in the mild group, and degree III and IV are in the severe group. the result shows mild group subjects have a higher level of VA concentration, and it is significant statistically(P<0.05)?This paper divided the RDS infants into three groups according to the fetal age, then made a comparison study of the three groups. The result shows the level of VA in RDS infants are lower than non-RDS infants when the fetal age is during 34 weeks and 37 weeks, and it is statistically significance(P<0.05).There is a distinct statistic significance between VA and the prevalence of RDS(P<0.001), the prevalence of RDS with the highest rate of 23.17%, when VA<0.35?mol/L, and when 0.35?mol/L ?VA<0.7?mol/L, the prevalence rate reduced to 10.37%, and it has the lowest prevalence rate of 1.52% when VA30.7?mol/L. Conclusion:(1)the serum level of late preterm infants suffering from RDS(34w to 37w) were lower than those with the same gestational weeks in non-RDS infants.(2)The relationship between serum VA concentration and the prevalence rate of RDS worth to be further study.
