Sažetak

Hyponatraemia is the most frequent disorder of body fluid and electrolyte balance in clinical practice. It is present in 15–30 % of hospitalized patients and can be manifested with a wide spectrum of clinical symptoms, ranging from very subtle to life threatening. Hyponatraemia is primarily a disbalance in water equilibrium, usually manifested as relative water overload in comparison to total body sodium and potassium concentration. Based on the time of development hyponatraemia can be defined as acute (< 48hrs) or chronic (≥48 hrs). Regarding serum sodium concentration, hyponatraemia can be mild (Na(s) 130–135 mmol/l), moderate (Na(s) 125–129 mmol/l) or profound (Na(s) < 125 mmol/l). When approaching a patient with hyponatraemia it is essential to determine whether hyponatraemia is acute or profound so we could immediately start giving a patient 3 % hypertonic saline. In absence of the above mentioned, the diagnostic algorithm, with emphasis on urine osmolality and urine sodium concentration, is guiding us towards more specific disorders which define proper therapeutic approach.
