Endotracheal intubation: an easy way to establish a patent airway in rabbits.

Endotracheal intubation of rabbits was accomplished by inserting a polyethylene catheter into the trachea through a guide needle which had been inserted into the trachea caudal to the larynx. The catheter was advanced cranially until it emerged from the mouth. The catheter then was used as a guide on which the tracheal tube was advanced. Adverse effects were not observed in intubated rabbits.
