  • Placing a tube in the trachea:
    • Ensures that airways remain patent in unconscious animals.
    • Prevents inhalation of substances (blood, saliva, stomach contents, etc).
    • Allows administration of oxygen and anesthetic gases.
    • Allows closed anesthetic circuit with no atmospheric pollution.

Uses

  • Providing supplementary oxygen.
  • Manual ventilation of patient in respiratory failure.
  • Maintenance of anesthesia with volatile anesthetic.
  • Prevention of aspiration during:
  • High risk of vomiting or regurgitation:
    • Esophageal obstruction.
    • Ileus.
    • Unfasted patients.

Advantages
