METHOD FOR DETECTING THE VOLUME OF SHUNT CIRCULATION ALONG DEVELOPED ARTERIOVENOUS FISTULA IN PATIENTS WITH CHRONIC RENAL FAILURE UPON PROGRAM HEMODIALYSIS

摘要

FIELD: medicine, nephrology.;SUBSTANCE: one should detect circulation rate characteristics and vessel's diameter due to dopplerography, moreover, on should measure vessel's diameter directly in area of anastomosis, as for circulation rate characteristics they should be determined in constant-wave Doppler mode in area of circulation's maximal rate. Moreover, one should measure anastomosis' cross-sectional area and heart rate, moreover, one should calculate circulatory volume through anastomosis by the following formula: V(ml/min) = A VTI HR, where A - anastomosis' cross-sectional area (sq. cm), VTI - integral of circulatory linear rate through anastomosis (cm), HR - heart rate.;EFFECT: higher accuracy of detection.;4 ex, 1 tbl
