本文报告64例曾作过血电解质检查及血气分析的尿毒症患者。旨在推定尿毒症时阴离子隙(AG)的影响因素及临床意义。血Na~+及血Cl~-浓度可影响AG(P<0.01)、AG降低常伴血Cl~-浓度异常(P<0.01),血HCO_3~-浓度和AG值关系不大(P<0.05),酸中毒程度和AG数值之间无对应关系(P>0.05)。认为AG是确定尿毒症酸中毒很有用的参数,但由于受许多因素影响,应用时务须注意。
This article reports 64 cases of uremic patients who had blood electrolyte tests and blood gas analysis. Aims To assess the influencing factors and clinical significance of anion gap (AG) in uremia. The concentration of blood Na ~ + and blood Cl ~ - could affect the AG (P <0.01), AG accompanied by the abnormal decrease of Cl ~ - concentration (P <0.01) ), There was no correlation between acidosis and AG values (P> 0.05). AG is considered a very useful parameter to determine uremic acidosis, but due to many factors, it is important to pay attention to the application.
