Alterations in the course of and histopathologic response to influenza virus infections produced by enflurane, halothane, and diethyl ether anesthesia in ferrets.
Alterations in the course of and histopathologic response to influenza viral infections by halothane, enflurane, and diethyl ether anesthesia were evaluated in ferrets. There were no significant differences in the incidence and duration of lethargy, pyrexia, rhinorrhea, or sneezing in infected animals given one of the three anesthetic agents under investigation, compared with those receiving no anesthesia. There were no differences in lung pathology in infected animals given one of the three anesthetic agents, or no anesthesia, though histopathologic changes in the nasal turbinates were significantly greater in ferrets given enflurane. This study suggests that general anesthesia administered to ferrets infected with influenza virus carries minimal morbidity, although enflurane anesthesia was found to produce greater histopathologic changes than the other agents.
