체외순환후 혈액응고 측정법의 비교 연구

Abstract

In order to determine the usefulness and practicability of the Hemochron system for the measurement of the coagulation time, we study fifty open heart patients comparing the coagulation time between Hemochron system method and Lee-White method. The coagulation time by Hemochron system is slightly shorter than by the Lee-White method. C7'59"±4'1l"(mean±S.D.) vs.8'32"±4'20"(mean± S.D.), 0.1>P>0.05J and there is a statistically significant correlation(r=0.94) and good linear relationship between the two method. We consider the measurement of coagulation time by Hemochron system for the determination of the heparin neutralization is a very convenient and time saving method.
