title: Investigation into the use of the laryngeal mask airway in pentobarbital anesthetized dogs.
abstract: OBJECTIVE
  To investigate the use of the laryngeal mask airway (LMA) in dogs.
  
  
  METHODS
  Prospective experimental study.
  
  
  METHODS
  Eight healthy adult mixed breed dogs weighing from 15 to 20 kg.
  
  
  METHODS
  The dogs were anesthetized with intravenous pentobarbital. An LMA was introduced after the induction of anesthesia and 1 L/min O2 plus 1 L/min air was delivered using a circle anesthetic system. Respiratory rate, tidal volume, arterial O2 saturation (pulse oximetry), end tidal CO2, inspired fraction of O2, pulse rate, and mean arterial blood pressure were measured after the insertion of the LMA and 30, 60, 90, and 120 minutes afterwards.
  
  
  RESULTS
  There were no changes in respiratory rate, tidal volume, arterial O2 saturation, and pulse rate during anesthesia. End tidal CO2 decreased significantly by the end of anesthesia and ventilation appeared satisfactory.
  
  
  CONCLUSIONS
  An LMA appeared to be an alternative option to maintain the patency of the airway in dogs.
  
  
  CONCLUSIONS
  This device may allow safe maintenance of an airway in dogs when intubation is difficult or when it interferes with the procedure (eg, cervical myelography).
