Tracheoscopy

Contributor(s): Sarah Pellett, Livia Benato

Introduction

  • Tracheoscopy is a procedure used to examine the trachea of a rabbit.
  • The endoscope can also be used to perform endotracheal intubation Endotracheal intubation.

Uses

  • Evaluation of the trachea and tracheal mucosa .
  • Detection of infection and collection of washings or biopsies for cytology, bacteriology and/or histopathology.
  • Removal of foreign bodies.
  • To perform endoscopic-guided endotracheal intubation.

Advantages

  • Can be curative if foreign objects are detected and removed.
  • Exudates, masses and foreign bodies can be visualized and samples can be readily obtained.
  • For intubating, endoscopy-guided intubation is faster and safer than 'blind' intubation.
  • Endotracheal tubes of the widest caliber possible can be used as the glottis is visualized.
  • The oral cavity is examined and there is no risk of introducing food into the trachea.

Disadvantages

  • A deep plane of anesthesia is required for tracheoscopy and tracheobronchoscopy investigations.
  • Small telescopes can only be used in larger rabbits and usually will only reach the tracheal bifurcation . Small flexible bronchoscopes are required for smaller rabbis and for bronchoscopy.
  • The mucosa of the trachea is sensitive, the head and neck must be kept extended and aligned to avoid any trauma.
  • Tracheobronchoscopy investigations are brief due to compromising gas exchange. Only use a small endoscope and if possible, introduce oxygen through the instrument channel of the endoscope.
  • Equipment relatively expensive.
