在重症治疗、内科、麻醉科领域内对代酸病人应用碳酸氢盐指针上存在明显争议,本文作者总结了过去4年来应用NaHCO_3的大量文献并提出个人看法。代酸分类广义代酸是指动脉血pH值<7.35,HCO_3~-浓度<21mmol/L。代酸有多种,有一种分类法是根据阴离子间隙(AG—anion gap),AG值是血浆内钠的容 There is a clear controversy over the use of bicarbonate pointers in acidosis patients in the fields of critical care, internal medicine and anesthesiology. The authors summarize a large body of literature on the use of NaHCO_3 over the past four years and present personal opinions. Substitution of acids Broad acidification refers to the arterial pH value <7.35, HCO_3 ~ - concentration <21mmol / L. A variety of acid, there is a classification is based on the anion gap (AG-anion gap), AG value is the plasma sodium content
