CENTRAL REGULATORY DISORDERS IN CLINICAL- PATTERN OF EARLY POSTOPERATIVE PERIOD IN PATIENTS WITH TUMORS OF MIDBRAIN

Neurological, clinical, biochemical examinations, electroencephalograp hy, computer and magnetic resonance tomography of the brain of 336 pat ients with brain stem and para-brain stem tumors resulted in conclusio n that nonspecific autonomic-endocrine reaction caused by disorders in central regulation was the main component of early postoperative peri od, The first type of such disorders included cases with rather stable indices of both hemodynamics and ionic-osmotic homeostasis characteri zed by favourable course. Unstable hemodynamics and tendency to increa se of osmolarity and serum levels of sodium and glucose as well as unf avourable course of this period were typical for the second type.
