小儿反复性肺炎与血微量元素关系的临床观察

Clinical observation on the relationship between repeated pneumonia and trace elements in blood in children

目的：观察小儿反复性肺炎的发生与血微量元素铅、铜、锌、钙、镁、铁含量的关系。方法：2006年9月2009年6月北京市密云妇幼保健院收治的反复性肺炎患儿56例为观察组,随机选择同期在北京市密云妇幼保健院门诊健康体检的小儿60例为对照组。分别测定两组患儿血铅、铜、锌、钙、镁、铁含量,并进行统计学比较。结果：56例反复性肺炎患儿血锌含量为（54.92±9.96）μmol/L,血铁含量为（7.29±1.21）μmol/L,对照组血锌含量为（59.94±9.35）μmol/L,血铁含量为（7.83±1.19）μmol/L,观察组较对照组减低,差异有统计学意义（P〈0.05,P〈0.01）。血铅、铜、钙、镁含量,观察组与对照组比较,差异无统计学意义（P〉0.05）。结论：部分小儿反复性肺炎的发生与血微量元素锌、铁缺乏有关。应对反复性肺炎患儿常规行血微量元素检测,对血微量元素缺乏者应予相应补充治疗。

Objective：To observe the relationship between the occurrence of repeated pneumonia and trace elements（lead,copper,zinc,calcium,magnesium,iron） in blood in children.Methods：56 children with repeated pneumonia in the hospital from September 2006 to June 2009 were selected as observation group,60 children receiving health examination in the hospital at the same period were selected as control group;the contents of lead,copper,zinc,calcium,magnesium and iron in blood in the two groups were detected,then statistical analysis was performed.Results：The contents of zinc and iron in blood in observation group were（54.92±9.96） μmol/L and（7.29±1.21） μmol/L,respectively,which were significantly lower than those in control group（（59.94±9.35） μmol/L and（7.83±1.19） μmol/L）（P〈0.05,P〈0.01）;there was no significant difference in the contents of lead,copper,calcium and magnesium in blood between observation group and control group（P〉0.05）.Conclusion：The occurrence of partial repeated pneumonia is related to zinc deficiency and iron deficiency in children;the children with repeated pneumonia need conventional blood trace elements test,for the children with trace elements deficiency,corresponding complement treatment should be taken.
