    AbstractThe new approach to intraoperative hemodynamics disorders prognostication which caused of inadequate anaesthesiological protection is presented in this research. Hemodynamic parameters stability both with systemic homeokinesis state were investigated in 28 patients with various surgical diseases. Their surgical operations were carried out with either of combinatory inhalation anaesthesia (halothane and neuroleptics) or noninhalation neuroleptnarcasis with ketamine. Instability of homeostatic regulation was controlled with special original analysis of cardiac rhythm entropy dynamics chaotisity in multidimensional faze space of existence. It is established that numerical criterion of cardiac rhythm chaotic state degree exceeds the intended acceptable level 5-10 minutes before clinical signs of hemodynamics instability developing in all inadequate anaesthesiological protection cases.
