将62例糖尿病患者按24h尿微量白蛋白值分为正常MA组,轻MA组和重MA组,设正常对照组20例。测定其尿酸化功能等。结果:各组血BUN、Cr、24h尿钾、动脉血pH无显著差异,糖尿病患者血钾、血CO2分压,尿NH4+、H+低于尿最初pH、HCO3、动脉血BE、负值高于正常对照组。重MA组与MA相比,血钾减低,尿最初pH、HCO3增加,尿NH4+、H+减低,血BE负值增大,血CO2分压减低。结论:糖尿病可引起尿肾小管酸化功能异常,引起低血钾。
62 cases of diabetic patients according to 24h urinary albumin values were divided into normal MA group, light MA group and heavy MA group, 20 cases of normal control group. Determination of uric acid function and so on. Results: There was no significant difference in BUN, Cr, 24h urinary potassium and arterial blood pH in all groups. The serum potassium, the partial pressure of CO2, urinary NH4 + and H + were lower than the initial urinary pH, HCO3 and arterial blood BE in patients with diabetes, Normal control group. MA weight MA group compared with the lower serum potassium, urinary initial pH, HCO3 increased urinary NH4 +, H + decreased, blood BE increased negative, partial pressure of blood CO2 decreased. Conclusion: Diabetes can cause urinary tubular acidosis dysfunction, causing hypokalemia.
