目的:探讨急诊患者低钠血症(HN)的发生与原发病的关系及预后。方法:回顾性分析我院2007年1月-2009年12月急诊收治的90例HN患者的临床表现和实验室检查。结果:年龄≥65岁老年人易产生HN,其中死亡7例。Binary Logistic回归分析结果显示,HN的预后与血钠水平和年龄密切相关,都可以看作是危险因素。结论:临床应重视对HN的认识,病因以肺部疾病、恶性肿瘤和中枢神经系统疾病最为多见。HN的预后与血钠水平和年龄密切相关。
Objective: To investigate the relationship between the occurrence of hyponatremia (HN) and the primary disease in emergency patients and its prognosis. Methods: The clinical manifestations and laboratory tests of 90 HN patients admitted to our hospital from January 2007 to December 2009 were retrospectively analyzed. Results: HN was easy to be produced in the elderly aged 65 or older, of which 7 died. Binary Logistic regression analysis showed that the prognosis of HN is closely related to serum sodium level and age, which can be considered as risk factors. Conclusion: Clinical knowledge of HN should be emphasized, with the most common cause of pulmonary diseases, malignant tumors and central nervous system diseases. HN prognosis and serum sodium levels and age are closely related.
