Abstract:
Objective To evaluate the hemorrheological changes after tourniquet deflation.Methods Twenty rabbits were subjected to lower extremity tourniquet inflation for 3 h. Venous blood samples were taken before tourniquet inflation and 2min after tourniquet deflation for measurement of hemorrheological parameters: low-shear viscosity and high-shear viscosity of whole blood; plasma high-shear viscosity , hematocrit; fibrinogen; aggreability,deformability and stiffness of erythrocyte; and blood sedimentation K value. The levels of parameters before tourniquet inflation served as baseline values. The gastrocnemius muscle samples were taken before tourniquet inflation and 5 min after torrniquet deflaion for observation of ultrastructure of small blood vessel.Results Compared with the baseline values, the levels of low- and high- shear viscosities of whole blood, plasma viscosity, fibrinogen, blood sedimentation K value, and aggreability and stiffness of erythrocyte increased significantly (P
