严重烧伤病人微量元素的动态变化

目的：了解重度烧伤后血及２４ｈ尿中七种微量元素的变化规律。方法：选择烧伤面积，３０％的病人１０例，动态测定伤后至创面基本愈合时血、２４ｈ尿中锌、铜，铁、钼、硒、铬的浓度，同时选择未烧伤者３９例正常对照组。结果：２４ｈ尿中七种元素排泄量均增加，血锌明显下降，铜、铬、钼水平增加、铁、硒、锰未见明显变化。结论：严重烧伤后微量元素代谢发生较大变化，但是否需要补充及何时补充仍值得探讨。

Dynamic changes of trace elements in severely burned patients

Objectives:To observe the dynamic changes in trace elements in severely burned patients. Methods:In this study serum levels and excretions in urine of zinc,copper ,iron,molybdenum,manganese,selenium and chromium were determined in 10 severely burned patients.They were also measured in 39 normal volunteers as controlled group. Results:During the treatment,a significant rise in urine output of all the seven trace elements was observed.However,the changes of serum levels varied.Zinc was the only decreased element in serum.Iron,manganese and selenium values changed insignificantly.Copper ,chromium and molybdenum values rised obviously( P <0.05). Colnclusions:The change in trace element is remarkable in severely burned patients,and there is need for the further research in their supply in these patients.
