The webinar presented by specialist anaesthetist, Prof Gareth Zeiler provides a comprehensive overview of inhalational anaesthetics, their pharmacokinetics, and clinical applications in veterinary practice. It covers the properties of commonly used drugs, such as Halothane, Isoflurane, Sevoflurane, and Desflurane, explaining their speed of onset, solubility, and potency. The presentation also delves into the functionality of vaporizers and breathing circuits, offering practical advice for safe and effective anaesthetic administration. Through detailed explanations and practical tips, it aims to enhance understanding and application of inhalational anaesthesia in the veterinary setting.
