ENT surgery presents particular challenges to anaesthetists because of the need for both the surgeon and the anaesthetist to have access to the patient’s airway. It is absolutely vital that the airway be secured during anaesthetic induction, but the surgical operations then performed on the airway may threaten this airway, which is a matter of concern to the anaesthetist. When the patient is being extubated, keeping the airway patent may be difficult because of oedematous passages, the placement of tampons and blockage or irritation of the airway resulting from bleeding. Thus, the end phase of anaesthesia in ENT operations is different from the usual pattern, and safe anaesthetic practice in such cases calls for both knowledge and experience. This chapter covers anaesthetic techniques used in patients having operations on the nose, including the entire period from before to after surgery and discusses the best methods to employ. Whilst there are three anaesthetic options in nasal surgery, i.e. local, sedation or general anaesthesia, the ideal techniques need to be both inexpensive and non-invasive whilst providing the optimal comfort for patients and ENT surgeons to carry out their work. |
