Abstract

Rheoencephalographic studies were carried out in victims with polytrauma with a prevalent component of severe traumatic brain injury, who were diagnosed with brain death on the basis of clinical criteria approved by Order No. 821 of the Ministry of Health of Ukraine (2013) and additional determination of oxygen tension in arterial blood and blood taken from the internal jugular vein. Both patients continued to be on artificial ventilation. With the help of continuous infusion of dopamine and phenylephrine, arterial hypotension and bradycardia are eliminated. Systolic blood pressure was adjusted to 180 mm Hg. The cardiac output was controlled with the help of tetrapolar thoracic rheography according to Kubicek. Nevertheless, effective hemodynamic support did not allow the registration of complexes of the rheoencephalogram, which in amplitude at least remotely indicated the presence of effective cerebral blood flow. The authors claim that the main place in the formation of impedance rheoplethysmogram complexes during the rheoencephalographic study belongs to the cerebral blood flow, and not to the blood flow in the scalp tissues.
