为探讨婴幼儿和反复呼吸道感染的病因,我科自1993年1月～1994年5月对门诊6个月～3岁反复呼吸道感染患儿随机检测了50例头发微量元素锌、铜含量.结果锌低于正常值者有43例,占86.0%,经统计学处理,P<0.01,差异非常显著;而铜低者14例,仅占28.0%,经统计学处理,P>0.05,差异不明显,无统计学意义.上述结果表明反复呼吸道感染与缺锌关系甚密.临床治疗中适当补锌很有必要.
To investigate the etiology of infants and children with recurrent respiratory tract infections, we randomly selected 50 children with hair zinc and copper contents from January 1993 to May 1994 for outpatients with recurrent respiratory tract infection of 6 months to 3 years old.Results There were 43 cases of zinc below normal, accounting for 86.0%, after statistical analysis, P <0.01, the difference was significant; while the low copper in 14 cases, only 28.0%, by statistical analysis, P> 0.05, the difference was not Obviously, no statistical significance.The above results show that the relationship between recurrent respiratory tract infection and zinc deficiency is very close.Appropriate zinc supplementation in clinical treatment is necessary.
