阴离子隙(Anion Gap,AG)代表血清中未测定阴离子(SO_4~-,HPO_4~-,有机酸~-,白蛋白~-)。尿毒症时由于SO_4~-、HPO_4~-积蓄,可使AG增高,血清HCO_3~-减低。为判明尿毒症时测定AG值的临床意义,我们对近年收治的尿毒症100例作了AG测算分析。100例中男64例,女36例,年龄16～76岁,40岁以下者48例。病因最多者属慢性肾炎65例。小球病变为主者共78例,小管间质病变为主者22例。血清肌酐5～7.9mg/dl 37例,8～12mg/dl 22例,>12mg/dl 41例。
Anion gap (Anion Gap, AG) represents the determination of serum anions (SO_4 ~ -, HPO_4 ~ -, organic acid ~ -, albumin ~ -). Uremia due to SO_4 ~ -, HPO_4 ~ - savings, AG can be increased, serum HCO_3 ~ - reduced. In order to determine the clinical significance of determining the value of uremia when uremia, we treated 100 cases of uremia in recent years made an AG calculation and analysis. 100 cases of male 64 cases, 36 females, aged 16 to 76 years, 48 cases under the age of 40. Most of the cause of chronic nephritis in 65 cases. There were 78 cases of pelvic lesions and 22 cases of tubulointerstitial lesions. Serum creatinine 5 ~ 7.9mg / dl 37 cases, 8 ~ 12mg / dl 22 cases,> 12mg / dl 41 cases.
