[Hypoxia and polytrauma].
The importance of polytrauma and hypoxia, resp., is discussed by the authors with regard to the mortality and the common effect of these is analysed. It was found that in the mortality of the patients suffered polytraumatism the first place (59,4%) is taken by such lesions, in which simultaneous lesion of the skull and the thorax occurs. The values of the blood gas and the acid-base balance of the patients who had suffered polytraumatism, were examined in the 12th--24th hours proceding the death. It was found that whereas--using the possibilities of the intensive therapy--the values of pH, paCO2 and BE could be kept in a part of the cases between the physiological limits--the paO2 value was under the normal value in all cases--moreover 2/3 of the values fell into the domain between 40--60 mmHg--signifying severe hypoxia. On the basis of the analysis it may be presumed that in the process leading to death of the patients who had suffered polytraumatism the anoxic hypoxy plays considerable role. This is supported also by the earlier data published by the institute, according to which the mortality in itself high--33.8%--of polytraumatism increases to 71.4%, if it is associated hypoxy. Consequently the aim of the therapy must be to exert the greatest activity in order to prevent or to combat, resp., the anoxic hypoxy.
