We successfully intubated 257 rats with a laryngoscope that we designed for
this purpose. Orotracheal intubation with this laryngoscope can be perform
ed quickly and without harm to the animal. This instrument provides direct
visualization of the vocal cords, allowing rapid, safe intubation of the ra
t. Maintenance of an adequate airway with endotracheal intubation is superi
or to tracheostomy for repeated experiments, and therefore this laryngoscop
e makes such studies easier and safer to perform.
