Microvascular pressure and functional capillary density in extreme hemodilution with low and high viscosity dextran and a low viscosity Hb-based O2 carrier.

This is the first experimental proof that in conditions of extreme hemodilution (Hct 11%) high plasma viscosity preserves microcirculatory function by maintenance of hydraulic capillary pressure and as a consequence maintenance of functional capillary density. This effect of plasma viscosity appears independent of tissue oxygen pressure on a local basis. Extreme hemodilution should therefore only […]
