The hemodynamic significance of the flow properties of blood was
put into perspective only during the past decade. Advances in
modern technologies today allow the quantitative analy- sis of the
fluidity of blood and its components under conditions approximating
the flow in vivo, particularly those in the microcirculation. The
hematocrit is the most important of the determinants of blood
fluidity (reciprocal value of blood viscosity); acute increases in
the hematocrit exert deleterious effects on circulation and oxygen
transport owing to impaired fluidity of blood. High viscosity of
plasma due to hyper- or dysproteinemias initiates the
microcirculatory dysfunctions in hyperviscosity syndromes.
Furthermore, the fluidity or deformability of red cells might be
critically diminished and therefore cause redistribution of blood
elements and adversely affect the resistance to flow within the
microvessels. In low- flow states blood fluidity most likely
becomes the key determinant for microvessel perfu- sion, overriding
the neural and local metabolic control mechanisms operative at
physiological conditions to adjust blood supply to tissue demand.
Microcirculatory disturbances are there- fore encountered whenever
driving pressures are reduced, as in shock or hypotension, and
distal to stenoses of macrovessels, but also in hemoconcentration
due to plasma volume con- traction, polycythemia, leukemia, and
dysproteinemia. Based on experimental studies exploring the
possibilities and limitations, with regard to improving the
fluidity of blood by reducing the hematocrit, the concept of
intentional hemo- dilution has been introduced to clinical
medicine.
