title: [Establishment of a hypothermic dog model to investigate airway rewarming].
abstract: OBJECTIVE
  In order to study airway rewarming method and rewarming devices for hypothermia, hypothermic dog model was established.
  
  
  METHODS
  The anesthetized dog was immersed in cold water at 16.7 degrees C until the esophageal temperature (Te) of the dog decreased to 34.0 degrees C, the core temperature and skin temperature were monitored by using a 12-channel scanning thermometers. Atracurium besylate, a skeletal muscle relaxant, was injected intravenously when the core temperature of the dog was basically steady after the dog was out of the cold water, the hypothermic dog model was established.
  
  
  RESULTS
  Rectal and esophageal temperature could stand for the core temperature of the hypothermic dog model, but mixing with each other was prohibited because of leading to mistakes. Administering of atracurium besylate could eliminate the effect of shivering on airway rewarming alone, hypothermic dog model in which shivering was inhibited could be used in determination of airway rewarming technique and rewarming devices for hypothermia.
  
  
  CONCLUSIONS
  Hypothermic dog model in which shivering was inhibited can abolish the interference of shivering, experimental repeatability is good, experimental method quite simple, and the model appropriate for application and dissemination.
