[Acid-base equilibrium in cerebrospinal fluid following intracranial surgery]. 1975

J Wroński, and J Tota, and J Zwoliński

In 48 patients the acid-base equilibrium in the CSF and blood was determined on the 2nd day after intracranial operation. In the postopertive period various disturbances of this equilibrium were found which were probably various stages of metabolic acidosis compensation in the CSF which was a reflection of metabolic (lactate) acidosis developing primarily in the damaged brain area. On the basis of determinations it was found that changes in the CSF of the type of metabolic acidosis (21 cases) corresponded most frequently to respiratory alkalosis in the blood (11 cases). Changes of the type of respiratory acidosis in the CSF(13 cases) corresponded usually to metabolic alkalosis in the blood (7 cases). The development of metabolic acidosis in patients in severe and moderately severe condition (19 cases) was associated with poor prognosis as to survival since the mortality in this group was 10 (about 53%). The favourable effect of dehydrating treatment may be due also to facilitation of passage of bicarbonates from the blood into the cerebral tissue and CSF since their level is increased in the blood during metabolic alkalosis (during a decrease in the extracellular space) resulting from dehydration.
