根因分析

采血或处理过程中的溶血释放细胞内钾，导致假性高钾血症；实际钾可能正常；忽略溶血指数会导致不必要的治疗（如胰岛素、葡萄糖酸钙），带来医源性风险。

English

Hemolysis during blood draw or processing releases intracellular potassium, causing pseudohyperkalemia; true potassium may be normal; ignoring hemolysis index leads to unnecessary treatment (e.g., insulin, calcium gluconate) with iatrogenic risks.

解决方案

  1. Check hemolysis index on lab report; if ≥ 2+, request recollection with proper technique (no fist clenching, use larger vein); run `python -c "print('Hemolysis index: check >2+; recollect if elevated')"`
  2. Order venous blood gas for rapid whole blood potassium, less affected by hemolysis
  3. If hemolysis index unavailable, repeat draw from opposite arm with minimal tourniquet time and avoid small needles

无效尝试

常见但无效的做法:

  1. 75% 失败

    If hemolysis is due to difficult draw or improper technique, repeat may show same artifact; need to check hemolysis index first

  2. 90% 失败

    Unnecessary treatment causes hypoglycemia; if potassium is actually normal, patient at risk of hypokalemia

  3. 80% 失败

    True hyperkalemia can be asymptomatic; correlation with hemolysis index is required, not clinical judgment alone
