Abstract
A 78-year-old man with influenza presented to the hospital. Initial blood tests revealed severe hemolysis accompanied by a decreased serum sodium concentration. However, repeat testing showed no hemolysis, and the serum sodium level was within the normal range. Notably, the serum sodium concentration in the initial sample, when measured using a blood gas analyzer, was also normal. These findings led to a diagnosis of pseudohyponatremia secondary to severe hemolysis. The underlying mechanisms of this condition are discussed herein.
摘要
一名78岁的流感患者入院。初步血液检查显示严重溶血，同时血清钠浓度降低。然而，重复检测未发现溶血，血清钠水平在正常范围内。值得注意的是，使用血气分析仪测量初始样本中的血清钠浓度时也是正常的。这些发现导致诊断为严重溶血继发的假性低钠血症。本文讨论了这种情况的潜在机制。
