[Disruption of thermal balance following removal of brain tumors].

The mechanisms of thermal disorders in the early postoperative period in neurooncological patients depend on the degree of irritation of the diencephalic sections. Temperature elevations in cases of a non-complicated postoperative course are caused by a mild irritation of the median formations resulting in a moderate reduction of heat emission and an insignificant elevation of heat production, the former playing the dominating role. Hyperthermia in the postoperative period complicated by the development of the diencephalo-catabolic syndrome is a consequence of severe irritation of the median structures resulting in disorders of thermoregulation, and it is predisposed by a sharply increasing heart production against the background of a significant reduction of heat emission at the expence of distinct disorders in central and peripheral haemodynamics.
