Endotracheal Intubation

Chapter 17 Endotracheal Intubation


Intubation of animals with normal upper airway anatomy is commonly performed using laryngeal visualization and insertion of an appropriate sized, cuffed endotracheal tube. An adequate level of anesthesia is required. After correct placement is confirmed, the tube is secured by tying it around the maxilla or mandible, being sure that the tie lies caudal to both canine teeth. Alternatively, a tube can be tied around the back of the head. The tube usually is connected to an oxygen source such as a Bain circuit or an anesthetic machine circuit. Finally, the cuff is inflated until it gently occludes the airway exterior to the tube. To determine how much cuff inflation is required, a manual breath is delivered while simultaneously inflating the cuff and listening for resolution of the air leak around the endotracheal tube.3


The possibility of a difficult intubation should be considered in animals with evidence of upper airway obstruction, trauma, or abnormal anatomy (e.g., brachycephalic breeds). Preplanning for intubation of cases such as these is essential to maximize the likelihood of success.
