Blood rheological abnormalities in the microcirculation during experimental traumatic shock.

OBJECTIVE

To find whether the principal indices of blood rheological disorders related to the microcirculation undergo drastic changes during the traumatic shock.

METHODS

RBC aggregability and deformability, as well as the systemic hematocrit, were assessed in white laboratory rats with the techniques that provided us with direct and quantitative data.

RESULTS

We found that in the experimental animals the RBC aggregability was sharply increased, the RBC deformability significantly decreased, while the systemic hematocrit underwent considerable lowering during the traumatic shock.

CONCLUSION

The blood rheological properties are significantly disordered during development of the traumatic shock.
