摘要
目的 研究早产儿血微量元素的含量及补充微量元素的意义。方法 采用日立 7170 A型全自动生化分析仪 ,测定 6 2例早产儿、 4 4例正常足月儿血清微量元素锌、铁、铜的含量 ,并对其中 4 2例血清微量元素水平降低的早产儿进行补充微量元素后的纵向观察。结果 足月儿血清锌、铁、铜值分别为 2 0 .86± 5 .32 μmol/ L、 2 3.84± 5 .6 6 μmol/L、 2 2 .6 7± 4 .5 3μm ol/ L ,早产儿血清锌、铁、铜值分别为 17.6 3± 4 .4 6μmol/ L、 19.75± 4 .2 4μmol/ L、19.2 6± 6 .2 1μmol/L ,早产儿血微量元素水平明显低于足月儿 (P<0 .0 1)。经微量元素治疗两周后 ,早产儿血清锌、铁、铜值均明显升高 ,达足月儿水平。结论 早产儿血清微量元素锌、铁、铜水平均低于足月儿 。
Objective To study the concentration of trace elements in premature infants and the meaning of supplying these trace elements.Methods We have tested the concentration of serum Zn?Fe?Cu in 62 cases of premature infants and 44 cases of full term newborn with Hitachi 7170 A Automatic Bio chemestry Analysis Machine and test 42 cases again with deficient trace elements after supplying trace elements.Results The concentration of serum Zn?Fe?Cu in full term newborn are 20 86±5 32 μmol/L,23 84±5 66 μmol/L.22 67±4 53 μmol/L.in premature infants are 17 63±4 46 μmol/L.19 75±4 24 μmol/L.19 26±6 21 μmol/L.respectively.It shows that the levels of serum trace elemets in premature infants are lower than those of full term infant(P<0 01).The concentration of serum Zn ?Fe?Cu?in premature infants increase significantly and reach to the normal level after supplying the trace elements for two weeks.Conclusion The concentration of serum Zn?Fe?Cu in premature infants are lower than those of the fullterm infants.It can return to the normal level with supplying the trace elements of routine doses in premature infants.
