INTRODUCTION
The combination of ageing, illness, and medications can lead to hyponatraemia or hypernatraemia.
AIMS
To describe the distribution of plasma sodium levels in older patients admitted to hospital.
METHODS
We carried out a hospital based cross-sectional study examining 1,511 serum sodium concentrations ([Na+]) among 336 elderly patients and attempted to elucidate the cause(s) of the abnormal serum [Na+].
RESULTS
The study population had a mean age of 81.4. Ninety-two (27.4%) patients had hyponatraemia and seven patients (2.1%) had hypernatraemia during their hospitalisation. The distribution of [Na+] results was towards the lower end of the normal range. The mortality rate of patients with hyponatraemia was 14.1% and that of patients with normal serum [Na+] was 8.9%. Six patients with hypernatraemia died in hospital. Lower respiratory tract infection and medication accounted for the majority of cases.
CONCLUSIONS
Deranged [Na+] is common among elderly patients admitted to hospital.
引言
衰老、疾病和药物的综合作用可导致低钠血症或高钠血症。
目的
描述老年住院患者血浆钠水平的分布情况。
方法
我们开展了一项基于医院的横断面研究，检测了336例老年患者的1511份血清钠浓度（[Na+]），并试图阐明血清[Na+]异常的原因。
结果
研究人群的平均年龄为81.4岁。92例（27.4%）患者在住院期间发生低钠血症，7例（2.1%）患者发生高钠血症。[Na+]结果分布趋向于正常范围的下限。低钠血症患者的死亡率为14.1%，血清[Na+]正常的患者死亡率为8.9%。6例高钠血症患者在医院死亡。下呼吸道感染和药物是大多数病例的病因。
结论
血清[Na+]紊乱在老年住院患者中很常见。
