[Dynamic monitoring of the severity of brain edema and swelling by separate impedance measurement in patients with severe craniocerebral trauma].

The dynamics of brain edema and swelling was studied according to the indices of separate impedancemetry in the early posttraumatic period in 36 patients with severe craniocerebral trauma. Swelling of the brain predominated on the 1st and 2nd days in most patients. Later, depending on the severity of the posttraumatic period, the swelling may grow or be replaced by edema with subsequent normalization.

[The differential diagnosis and treatment of brain edema and swelling].

Data is reported in evidence of the possibility of using separate impedancemetry for intravital diagnosis of the degree of manifestation and the dynamics of development of brain edema and swelling. The specific features of the effect of mannite, furosemide, sorbitol, dexamethasone, and thiopental sodium on brain edema and swelling were studied in the clinic under control of impedancemetry in patients with craniocerebral trauma of various severity and edema and swelling of different degree of manifestation. Experimental study on a model of intracerebral hemorrhage showed that mannite, furosemide, and dexamethasone act on the dynamics of edema and swelling in phases.
