Endotracheal intubation in rabbits is challenging due to their unusual anatomy. Here we present a technique for direct intubation of the trachea using a polypropylene catheter as a guide. This method utilizes relatively inexpensive supplies, requires minimal training, and can be easily performed in any clinical setting.

FAQs
The rabbit’s narrow oral cavity, large tongue, and sharply angled larynx restrict the working space and make the glottis more difficult to access. These anatomical features increase the importance of careful positioning, direct visualization, and gentle handling. Recognizing the constraints helps reduce airway obstruction and supports more consistent airway control during anesthesia and research procedures.
A laryngoscope helps the operator visualize the larynx and glottis rather than advancing the tube without direct guidance. This is particularly important because the rabbit’s oral and laryngeal anatomy can make the airway difficult to access. Improved visualization supports accurate passage through the glottis, limits unnecessary manipulation, and contributes to safer, more reproducible anesthesia.
Once correctly positioned in the trachea, the endotracheal tube provides a protected route for delivering inhaled anesthetics and supplying oxygen. It also permits controlled or mechanical ventilation when respiratory support is needed. Maintaining this airway can improve oxygenation and reduce risks associated with airway obstruction or aspiration during surgical, physiological, and respiratory studies.
A suitably sized tube is necessary because the rabbit airway is narrow, while excessive force can compromise the delicate passage through the glottis. Gentle advancement helps the operator respond to the rabbit’s challenging anatomy and avoid unnecessary trauma or obstruction. Appropriate tube selection and handling therefore contribute to reliable airway maintenance and animal welfare.
The workflow centers on preparing the rabbit for anesthesia, positioning it to improve airway access, visualizing the larynx with a laryngoscope, and gently advancing a suitably sized tube through the glottis into the trachea. The airway is then maintained for oxygen delivery, inhaled anesthesia, or ventilation. Consistent execution improves procedural reliability across experiments.
Researchers may use this airway technique during studies involving surgery, physiology, or respiratory function when stable anesthesia and controlled breathing are required. A standardized approach helps maintain oxygenation, supports comparable experimental conditions, and improves animal welfare. Consistent airway management can also strengthen the reliability of outcomes by reducing variation caused by obstruction or inadequate respiratory support.
