Endotracheal intubation of the dog and cat

Abstract

Endotracheal intubation is performed for general anaesthesia, critical care, and emergency situations. As the veterinary surgeon often performs this procedure, it may be under-developed, or minimally practiced by veterinary nurses (VNs) despite being legal to perform in several countries. As an emergency skill, and as the role of VNs grows, this article aims to act as a resource for VNs wanting to learn to perform endotracheal intubation correctly. This article will only review the purpose of endotracheal intubation, the relevant anatomy and physiology, equipment, techniques, and troubleshooting. It will not offer a detailed comparison of endotracheal intubation versus laryngeal mask airway, nor will it discuss the technique for endotracheal tube cuff inflation as the full scope of published data, experiences and opinions could not be given due justice: moreover, this is an area of the skill VNs are already familiar with. Maintenance of the in-situ tube and extubation are also excluded and all of these subjects warrant further discussion in a separate article.
