糖尿病酮症酸中毒(DKA),不管感觉中枢变化的程度如何,只要血浆HCO_3~-浓度≤9mEq/L的病例,都归为糖尿病昏迷(DC)。HCO_3~-低于9mEq/L,尤其是pH<7.1,这只是标志病人预后不良,此外还有极度高血糖及高渗透压,总体液和电解质的极度缺乏,以及循环衰竭等另一些表现。目前DKA和DC虽经胰岛素治疗,但死亡率仍在5～15％。 Diabetic ketoacidosis (DKA), regardless of the degree of central sensory changes, is classified as diabetic coma (DC) as long as the plasma HCO 3 3- concentration is less than or equal to 9 mEq / L. HCO 3 3- to below 9 mEq / L, especially pH <7.1, is indicative only of poor patient outcomes, in addition to extreme hyperglycemia and hypertonicity, extreme lack of total fluid and electrolytes, and circulatory failure. Although DKA and DC are treated with insulin, the mortality rate is still 5-15%.
