A is for airway: intubation guide for common species (part 1)

Endotracheal intubation is a vital aspect of anaesthetic management in veterinary patients. It enables the delivery of volatile inhalants with 100% oxygen, reduces hypoxia risk, prevents environmental pollution and safeguards the airway against regurgitation and aspiration. Successful intubation requires knowledge of patient anatomy, appropriate endotracheal tube (ETT) and species-specific techniques. Proper measurement of ETTs, especially in smaller species, prevents complications such as bronchial intubation, which can cause uneven ventilation and hypoxia. This article reviews the types of ETTs, including Magill, Murphy, Cole and armoured tubes, discussing their materials, uses and features. It also addresses managing difficult intubations, highlighting essential preparation, equipment and techniques for challenging cases. A thorough understanding of intubation principles and preparation is essential for safe anaesthetic outcomes in veterinary practice.
