Electromyographic Endotracheal Intubation in Pig: A Technique to Insert Electromyographic Tube Inside the Pig Trachea

Begin by placing a three to four-month-old piglet in the prone position on the operating table, with the head and body aligned, to facilitate a clear visualization of the upper airway. Have an assistant apply traction of the upper and lower jaw to maintain an adequate mouth opening, and place the laryngoscope upside down directly into the oral cavity to depress the tongue.

Use the laryngoscope to press the epiglottis downward toward the tongue base, gently advancing the elastic bougie into the trachea, when the vocal cords can be clearly visualized. Advance the electromyography, or EMG, tube at the corner of the mouth to a depth of 24 centimeters, and use medical tape to fix the tube at the mouth angle, then, connect the EMG tube to the ventilator.
