[Acid-base balance and electrolytes in cerebrospinal fluid of patients with bacterial and lymphocytic meningitis].

Acid-base balance and electrolytes concentration in cerebrospinal fluid (CSF) of patients with bacterial and lymphocytic meningitis were assessed. Inflammatory process causing the damage of blood-brain barrier and brains hypoxia leads to statistically significant changes of pH, pO2, bicarbonates and K+ concentrations in CSF of patients with bacterial meningitis, which in lymphocytic meningitis were not observed. Patients with fatal; outcome of bacterial meningitis showed higher CSF's acidosis and lover bicarbonates with higher K+ concentrations, which suggest deeper damage of brain hemostasis regulating mechanisms in those patients.
