METHOD OF DIAGNOSTICS OF NERVOUS SYSTEM DISORDERS WITH LONG-TERM INFLUENCE OF VINYL CHLORIDE Russian patent published in 2017 - IPC A61B5/484 A61B8/06 

FIELD: medicine.

SUBSTANCE: anti-orthostatic test and ultrasound dopplerography of extracranial vessels are performed and visual, cognitive and auditory evoked potentials are recorded. Indicators are defined: amplitude and latency P2 of visual evoked potential, latency P300 of cognitive evoked potentials, latency P2 of auditory evoked potentials, amplitudes N1 of auditory evoked potentials, and index of reactivity in holding anti-orthostatic test. Based on the obtained indicators, taking into account discriminatory coefficients, the discriminant function (F) is calculated. Result are compared with a constant of 79.9. When F is less than or equal to the constant, the absence of signs of damage to the nervous system associated with influence of vinyl chloride is diagnosed. When F is greater than the constant, signs of damage to the nervous system associated with influence of two vinyl chloride are diagnosed.

EFFECT: method helps to increase the reliability of diagnosis by identifying signs of damage to the nervous system at the donorological stage of intoxication with vinyl chloride.
