低钠血症是住院患者中常见的电解质异常，通常作为其他潜在疾病的首发症状。严重的低钠血症可能危及生命，需要及时诊断和治疗。我们报告一例难治性低钠血症，诊断困难，需要长期住院治疗。由于不太可能的24小时尿液检查，最终怀疑诊断为原发性烦渴，并通过完全切断患者病房浴室水龙头的形式完全清除自由水通路予以证实。原发性烦渴的诊断和治疗将进一步讨论。
Hyponatremia is a common electrolyte abnormality among hospitalized patients and often present as first sign of other underlying medical conditions. Severe hyponatremia can be life threatening and requires prompt diagnosis and treatment. We present a case of refractory hyponatremia that was a diagnostic challenge requiring a prolonged hospitalization. Diagnosis of primary polydipsia was ultimately suspected due to improbable 24-h urine studies and confirmed through complete removal of free water access in the form of disconnecting the bathroom faucet in the patient’s hospital room. Diagnosis and management of primary polydipsia is further discussed.
