不同烧伤面积血清、尿、水泡液中Zn、Cu、Fe、Ca、Mg的动态比较

为探讨烧伤病人伤后血清、尿和水泡液中Ｚｎ、Ｃｕ、Ｆｅ、Ｃａ、Ｍｇ的含量，观察了１０６例烧伤病人（Ｌ组烧伤≥３０％ＴＢＳＡ，５７例；Ｓ组烧伤＜３０％ＴＢＳＡ，４９例）伤后１，２，３，７，１４，２１，２８天血清、尿和水泡液中Ｚｎ、Ｃｕ、Ｆｅ、Ｃａ、Ｍｇ的动态变化。发现除血清Ｆｅ第１天高于正常值外，其它各元素都减低，Ｌ组比Ｓ组减低明显。尿Ｚｎ、Ｃｕ、Ｆｅ排出明显增多，尿Ｃａ、Ｍｇ排出减少。水泡液Ｚｎ、Ｆｅ、Ｃａ与血清正常值近似，Ｃｕ、Ｍｇ略低于血清正常值。说明烧伤后血Ｚｎ、Ｃｕ、Ｆｅ、Ｃａ、Ｍｇ的降低与从尿液及创面丢失有关。

Changes in contents of Zn,Cu,Fe,Ca,Mg in serum,urine and blister fluid after burn injury

burned patients were divided into two groups:group L consisted of 57 patients with burns larger than 30% TBSA,and group S consisted of 49 patients with burns smaller than 30% TBSA.The contents of Zn,Cu,Fe,Ca,Mg in serum,urine and blister fluid were determined on 1, 2, 3, 7, 14, 21, 28 days after burn injury.The results indicated that all of the elements in serum were decreased except serum Fe on first day,and the levels were much lower in group L than in group S.The contents of Zn,Cu,Fe in urine were increased significantly and Ca,Mg in urine decreased.The contents of Zn,Fe,Ca in blister fluid were similar to normal values of serum,and Cu,Mg in blister fluid were less than that of serum.The studies indicated that the decrease in contents of Zn,Cu,Fe,Ca,Mg after burn injury was propably related to loss of these elements from urine and wound.
