严重烧伤休克期不同时段血清阳离子的变化

目的:探讨严重烧伤休克期不同时段血清阳离子发生变化的原因和机制,为临床休克期补液提供依据。方法:对121例重度以上烧伤病人休克期不同时段的377次电解质结果进行回顾性分析。结果:严重烧伤休克期病人的血清阳离子随着时间的发展呈下降趋势,与对照组相比较,各时段的钾、钙离子均有极显著性差异(P<0.01),0～8 h的血清钠无差异,8～16 h与>16～24 h的血清钠有显著性差异(P<0.05),24～48 h以及>48～72 h的血清钠有极显著差异(P<0.01)。各组间的方差有显著性差异(P<0.05或(P<0.01)。结论:严重烧伤休克期不同时段血清阳离子的变化是明显的,呈下降趋势,与电解质丢失过多、补充不足以及容量稀释有关,改善补液的质量对预防电解质紊乱有帮助。

Study on serum cation of patients with severe burn during shock period

Objective To study the change and mechanism of serum cation in the patients with severe burn during shock stage. Methods: 121 patients with severe burn during shock stage were examined with serum electrolyte for 377 times. Results:The means of serum potassium ion and calcium ion of all study groups in the patients with severe burn were significantly lower than that of the control group(<0.01).Conclusions:The change of serum cation in the patients with severe burn during shock stage was markedly. It trend to descend, which was associated with losing over serum electrolyte, infusing less and diluting blood volume. Improving the quality of fluid will be helpful for preventing disturbance of electrolyte.
