[Experimental study of circulatory dynamics following inhalation injury in dogs].
Early changes in respiratory and circulatory dynamics before and after steam-inhalation injury were made in a dog model were studied. The results showed that the resistance of the respiratory system was significantly higher 3 hours and 4 hours post injury than that before injury (P < 0.05), the compliances of both the lung 4 hours post-injury and the respiratory system 3 hours psot-injury significantly decreased (P < 0.05), and the heart rate markedly lowered (P < 0.01), and the cardiac output also decreased (P < 0.05) 2 hours after injury. It is suggested that the early changes in the respiratory and circulatory dynamics may be used as markers for the diagnosis and treatment of the inhalation injury.
