title: [Statistical correlation between lactate concentration and acid-base equilibrium in cases of brain tumors, craniocerebral injuries and meningitis].
abstract: Statistical significance of correlations between lactate concentration and pH value as well as pCO2 in the cerebrospinal fluid was assessed in patients with brain tumours, craniocerebral injury and meningitis. After calculation of correlation indices it was found that with increasing lactate level the correlation between this level and the pH and pCO2 of the cerebrospinal fluid increases. Correlation coefficients were far from their maximal values (+1 or -1) which indicates absence of a direct cause-and-effect relationship between lactate concentration and both remaining values. The analysis of results in the group with lactate level exceeding 30 mg/100 ml demonstrated lowest correlation coefficients between these values in patients with meningoencephalitis.
