Severe blood loss treated with Hyper-Viscosity

Researchers from UC San Diego have come up with a radically different solution for severe

blood loss treatment. In their study, fluids with much higher salt content than conventional

saline are combined with viscosity enhancers with the purpose of thickening blood.

Increasing blood viscosity would seem the wrong approach to restore flow through tissues.

However, results based on animal trials suggest that enhancing blood viscosity significantly

increases functional capillary density, a key parameter in healthy blood flow through tissues

and organs. This resulted in an increase in resuscitation rates after severe blood loss was

induced.

This seemingly contradictory effect is explained by an increase in size of small blood vessels

(dilation) caused by the higher shear stresses exerted by the blood with higher viscosity after

treatment.
