METHOD OF EXPRESS ESTIMATION OF HEMOSTASIS SYSTEM FUNCTIONAL STATE

摘要

FIELD: medicine.;SUBSTANCE: blood sample is placed in capillary, in whose walls installed are electrodes connected to frequency generator and registering unit, blood electric conductivity is measured at the moment of passing through it of alternating current with frequency 200 Hz, electric coagulogram is registered and used to determine chronometric and amplitude characteristics: A - amplitude of functional curve decline, mV; N - time of functional curve decline to minimal value in minutes. If value of A/T index decreases or increases with respect to normal, conclusion about hemostatic disorders is made. If value of A/T index equals 3-5 - hemostasis state is evaluated as normal, if A/T value is lower than 3, hypocoagulation is determined, and if A/T value is higher than 5 - hypercoagulation.;EFFECT: application of the method makes it possible to obtain data about hemostasis system state in real time mode, without injuring form blood elements in investigated microvolumes of blood, thus making it possible to increase accuracy, self-descriptiveness and efficiency of hemostasis state evaluation and to carry out correction of performed therapy without delay.;4 dwg, 3 ex
