儿童末梢血测微量元素含量的临床意义

目的:末梢血测儿童微量元素含量的变化,指导临床合理补充微量元素。方法:采用原子吸收分光光度法检测980例儿童末梢血锌、铁、钙、铜、镁含量。结果:980例儿童锌、铁、钙3种微量元素缺乏比较普遍,锌缺乏率19.5%,铁缺乏率16.1%,钙缺乏率15.2%。铜缺乏率2.0%,镁缺乏率2.1/%。在年龄上有统计学意义,但在性别上无统计学意义。结论:儿童检测微量元素很有必要,有利于临床及时指导儿童合理地补充微量元素,可以避免盲目性。

Clinical significance of microelement level in peripheral blood of children

Objective:To understand the changes of trace elements in peripheral blood of children,and guide rational supplement of trace elements in clinic.Methods: Atomic absorption spectrophotometric method was employed for detecting levels of zinc,iron,calcium,copper and magnesium in peripheral blood of 980 children.Results: Zinc,iron and calcium were general insufficient among the 980 children,the insufficient rates of them were 19.5%,16.1% and 15.2% in turn,while those of copper and magnesium were 2.0% and 2.1%.The levels of these microelements had statistical significance among ages,but not in sex.Conclusion: Microelements detection was necessary in children,which contributed to guide rational trace elements supplement in children without blindness.
