摘要
为探讨烧协病人伤后血清、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。
106 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, 2l,28 days after burn injury.The results indicated that all of the elements in serum were decreased ex- cept 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.
