Hyponatremia is the most common electrolyte disturbance seen in hospital practice. Severe hyponatremia can be life threatening and is associated with considerable mortality.

Aim

To assess the prevalence of severe hyponatremia (plasma Sodium <120 mmol/l) by retrospective analysis in a hospital population and its laboratory investigation, management and clinical outcome.

Results

Over a six-month period 77 patients (men 50: women 27) were identified with severe hyponatremia. The mean patient age was 73+14 years. The mortality rate was 27%. 70% of patients were admitted through medical speciality. The mean initial plasma sodium concentration was 116+4 mmol/l. The mean rate of rise of sodium was 3.06+3 mmol/l in 24 hours. Collapse or falls is the commonest cause of admission. 5% were on SSRI, 38% of patients were on diuretics, 8% were postoperative. Serum osmolality was measured in 32% % of patients, 27% had urine osmolality, 10% had urinary sodium measured. 42% had thyroid function tests, 92% had liver function tests. 13% had tests to exclude hypoadrenalism. 32% of patients were fluid restricted and 5% of patients were treated inappropriately with 5% dextrose

Conclusion

Severe hyponatremia, although rare is a serious abnormality commonly seen in elderly population admitted to the hospitals. Local guidelines in investigation and management of hyponatremia may help in optimising patient’s care.
