[The efficacy of hyperbaric oxygenation in experimental and hemorrhagic shock].
The efficacy of hyperbaric oxygenation (HBO, 2 atm, 1 h, altitude chamber "Irtysh-MT") has been studied in acute experiments on 56 adult dogs with hemorrhagic and traumatic shock. It has been established that HBO has a marked therapeutic effect in hemorrhagic shock, especially in its early period, when almost all the animals are saved from death. In the late period of hemorrhagic shock and in the early period of traumatic shock HBO effect was manifested only in insignificant increase in the animals' survival and lifespan. In the late period of traumatic shock toxic effect of hyperbaric O2 application was observed and the majority of animals died before the end of HBO session.

[Pathogenesis of intra-operative disruption of hemodynamics during hemodialysis of patients poisoned by phosphorganic insecticides, complicated by the development of exotoxic shock].
The results of central hemodynamic and myocardial contractility studies during hemodialysis in 62 patients with severe fluoroorganic insecticide poisoning complicated by exotoxic shock are reviewed. It has been established that hemodynamic disturbances are manifested in progressing fall of venous pressure, stroke volume and cardiac output accompanied by the onset of phase myocardial hypodynamia syndrome. The leading role of hypovolemia resulting from ultrafiltration in the pathogenesis of the above hemodynamic disturbances has been revealed. The results obtained make it possible to outline approaches aimed at correction of intraoperative hemodynamic disturbances and to increase safety of extracorporeal hemodialysis.
