[Acid-base equilibrium in patients with tick-borne encephalitis and similar diseases].

The study is concerned with the acid-base balance in 92 patients with tick-borne encephalitis, tick-borne fever and meningitis of an obscure etiology. In many cases there was a shift in the direction of a metabolic acidosis, which was most vividly expressed in the meningitic form of tick-borne encephalitis. Some of the patients were treated by sodium bicarbonate which exerted a positive effect. The degree of changed indices of the acid-base balance and the time of their appearance helps in the diagnosis of tick-borne encephalitis correct evaluation of the severity of the condition and timely prescription of correction therapy.
