Which statement about head alignment in gavage is correct?

• A. The head should be in vertical alignment with the esophagus during gavage.
• B. The head should be tilted upward.
• C. The mouth should be open wide.
• D. The entire procedure should be performed without restraint.

Answer: (A)

Maintaining the head in vertical alignment with the esophagus is essential because it creates a straight, unobstructed path from the mouth down into the esophagus. This positioning helps guide the gavage tube into the esophagus rather than the trachea, reducing the risk of misplacement, airway irritation, or injury to the mouth and throat. Tilting the head upward can misalign the airway and bias the tube toward the trachea or create angles that hinder advancement. Opening the mouth wide isn’t necessary and can reduce control of the instrument, increasing the chance of injury. Attempting the procedure without restraint introduces movement that can lead to misplacement and trauma; gentle restraint improves safety for both the animal and the operator. In short, keeping the head aligned with the esophagus ensures a direct, safer route for the tube.
