Burn injury is one of the most stressful factors. In response to any stress the body changes defensive adaptation and adaptive reactions for the regulation of which, on a subconscious level, autonomic nervous system (ANS) is responsible, by antagonistic interaction of its sympathetic and parasympathetic divisions. The same principles are peculiar to eastern-philosophical concept of Yin and Yang, philosophical law of unity and struggle of opposites etc. Understanding the special features of ANS activity in patients with burns of various severity allows to evaluate adequately their general condition and increase the efficiency of treatment and rehabilitation measures. That is why the purpose of our research was to study the functional state of autonomic nervous system of patients with burns of various severity. The research involved diagnostics of the functional state of autonomic nervous system in 90 patients with burns of various severity according to the methods of V.G. Makats using the device VITA-01-M. Depending on the severity index, injuries were divided into 3 groups, 30 victims in each group. The first group consisted of burnt patients with the severity index (SI) 60-90 units, second - 91-120 units, third - above 120 units. All patients took infusiontransfusion therapy, early surgical necrectomy on 2-3 day, xenoplastic transplantation. Wounds were treated in a humified box. The research was conducted from 10 to 12 hour on 1, 3, 7, 14, 21 and 50 day. After computer processing of obtained results and analysis of the dynamics of functional energy information systems activity, we determined the index of vegetative homeostasis (IVH). Obtained results allowed finding out that the state vegetative equilibration was restored only in patients with SI of 60-90 units on 50 day of observation. Patients with SI of 91-120 units were in a state of parasympathetic activity compensation. Patients with SI of more than 120 units remained in a state of evident parasympathetic activity. It was established that recovery of vegetative equilibration in the body of burnt was achieved by a pathological way due to a sharp depression of some biologically active zones and activation of others. Significant disturbance of energy circulation through functional energy channels requires its correction, which is treated as an urgent tendency of psychosomatic rehabilitation of patients with burns.
