In humans, arteriovenous extracorporeal membrane oxygenation (AV-ECMO) is a life support technique capable to assume in part or totally lungs functions, when these are not able to promote appropriated hematosis. To know the viability of this method in dogs (Canis familiaris), the present study applied AVECMO in ten adult mixed-breed dogs, with expected three hours of duration to each experiment. In Group 1 (n=4), mechanical ventilation and dopamine continuous infusion were associated with the extracorporeal support. In Group 2 (n=6), any other measure of intensive care was used concomitantly AV-ECMO. Blood gas analysis and lactate levels were evaluated every 10 minutes and one hour, respectively, from arterial blood samples. Inotropic support improved the blood flow through the circuit promoting a better tissue perfusion with oxygenated blood, suggested by the lactate and mean arterial pressure levels measured. Mechanical ventilation used simultaneously with AV-ECMO was able to further improve levels of blood gases. Therefore, if applied along intensive care support, AV-ECMO is a viable technique for use in dogs with respiratory failure refractory to conventional treatments. Source
