[Investigations of pathogenesis of reactions in circulation and respiration during the implantation of bone cements. animal experiments (author's transl)].

This paper shows the effects of the increase in pressure in the medullary cavity in the blood circulation and the respiration observed during implantation of bone cement with animal experiments. The pathomechanism is also examined. The reactions of the respiration and the circulation, when observed, resulted in the intramedullary increase in pressure. These are nerval reflexes caused by the innervation in the medullary cavity and are not reactions of the monomer, which may come into the circulation during the polimerization of bone cement. These reactions are very different from those caused by the fatal obstruction of the pulmonary blood vessels through bone marrow ingredients. This is the effect of an insufficient prevention of increase in medullary pressure during cement implantation.
