阴离子间隙(AG)是基于血清呈电中性状态的一个概念。本文报道了99例慢性肾小球肾炎尿毒症期患者的AG测定结果,并探讨其临床意义。我们的资料表明,尿毒症期患者AG值和AG>16mEq/L,百分比均高于对照组。以尿毒症晚期和早期相比,前者亦高于后者,说明AG值的测定确可作为判定肾功能损害程度的有用指标。对AG增大与尿毒症酸中程度不一致的患者。应注意寻找有无肾小管性酸中毒及其它导致AG降低的因素存在。此外,作者还讨论了AG值的单位问题。
Anion gap (AG) is based on the concept that serum is electrically neutral. This article reports 99 cases of chronic glomerulonephritis patients with uremia in the determination of AG, and to explore its clinical significance. Our data show that patients with uremia AG values and AG> 16mEq / L, the percentage was higher than the control group. Compared with the early uremic late and early, the former is also higher than the latter, indicating that the determination of AG value can indeed be used as a useful indicator to determine the extent of renal damage. AG increased uremia and uremia in patients with varying degrees of acid. Should pay attention to find whether there is renal tubular acidosis and other factors that lead to AG exist. In addition, the author discusses the unit of AG value.
