[Normovolemic hemodilution and cerebral edema].

For the purpose of an experimental study a cerebral oedema was produced in dogs by means of a criogenic wound. The dogs were divided into 4 groups. There was no treatment in the first group. The standard treatment with corticoids was applied in series 2 and 3. Moderate normovolaemic haemodilution was applied in the 4th group. In all cases we studied the evolution of the intracranial pressure, Na and K in C.S.F. and the Na-K ratio in the urine. The results obtained demonstrate that moderate normovolaemic haemodilution represents a valid alternative treatment in cases of cerebral oedema.
