[Water-electrolyte disorders in the acute period of a stroke]

In 100 patients with different forms of cerebral strokes the author studied the general water content. Its distribution in the organism. Na and K concentration in the plasma and erythrocytes and the general electrolyte content in spaces of the body. It was established that the most frequent syndromes of water-electrolyte disorders in the acute period of strokes is intracellular or general hydratation (81%). In parenchymatous-subarachnoidal hemorrhages the general dehydratation was combined with a hyperhydratation of the extracellular space, while in sichemic strokes there was an anhydridemia up to 10-18 days. A disturbance of the electrolyte metabolism was also expressed in a transmineralization with a drop of the general Na and K content due to intracellular losses. The K deficit was averagely 29% and the Na--15.5% and should be taken into consideration in a substitutive hydro-electrolyte therapy. Solutions with an increased K content should be used in order to compensate its deficit.
