Abstract

Endotracheal intubation is a critical skill in veterinary anaesthesia, requiring knowledge of species-specific anatomy and techniques. This article explores intubation methods, endotracheal tube selection, securing techniques, placement confirmation, cuff inflation and extubation across various species, including canines, felines, rabbits, guinea pigs and avians. Key considerations include anatomical differences, risk factors such as laryngospasm in felines and rabbits, and alternative airway devices like supraglottic airway devices. Proper technique and monitoring, including end-tidal carbon dioxide assessment, enhance patient safety and successful intubation. Veterinary nurses and technicians must adapt their skills for optimal airway management across species.

When it comes to endotracheal intubation, it is important to know the associated anatomy and what to look for when attempting intubation in the species that is being anaesthetised. This article will cover the different ways, the steps to successfully intubate the patient, the appropriate range of endotracheal tubes (ETTs), how to secure the ETT, the ways to confirm the correct placement, cuff inflation techniques and extubation in canine, feline, rabbits, guinea pig and avian patients.

Endotracheal intubation is commonly performed in sternal recumbency after anaesthesia is induced. Sufficient induction agent(s) should be administered to ensure that the swallow reflex is abolished and to prevent excessive coughing around the ETT. In some cases, intubation may need to be performed in lateral recumbency—for example, in patients with a fractured limb, a head injury (eg following a road traffic accident), or those requiring cardiopulmonary resuscitation (CPR) and who cannot be moved (Auckburally and Flaherty, 2017).
