[Comparative study of intravital microcirculation and hemorheological changes following burn injury of different severity in rats].

It was shown in experiments on rats that burn injury is followed by microcirculatory disturbances, hemoconcentration and increasing blood viscosity that is especially pronounced in the vessels with low blood pressure. The microcirculatory changes in the mesentery correlated with the in vitro investigated dynamic viscosity and blood composition. The disturbances were more pronounced after severe burn followed by a mortal shock than after moderate burn without fatal consequences. This investigation confirms great importance of hemorheological changes and microcirculatory disturbances in the early period of burn disease.
