Central regulatory disorders in clinical pattern of early post-operative period in patients with tumors of midbrain

Neurological, clinical, biochemical examinations, electroencephalography, computer and magnetic resonance tomography of the brain of 336 patients with brain stem and para-brain stem tumors resulted in conclusion that nonspecific autonomic-endocrine reaction caused by disorders in central regulation was the main component of early postoperative period, The first type of such disorders included cases with rather stable indices of both hemodynamics and ionic-osmotic homeostasis characterized by favourable course. Unstable hemodynamics and tendency to increase of osmolarity and serum levels of sodium and glucose as well as unfavourable course of this period were typical for the second type.
