Summary

Extubation and emergence are high-risk phases of anaesthesia which accounted for 28% of the anaesthesia cases reported to the Fourth National Audit Project of the Difficult Airway Society and the Royal College of Anaesthetists. Problems generally relate to the patient’s anatomy, physiology or to the context in which extubation is carried out. Minor issues such as coughing and breath-holding are common, more serious complications such as aspiration, laryngospasm, post-obstructive pulmonary oedema and hypoxic brain injury are often preventable with proper planning. In this chapter we discuss how to formulate an extubation strategy including risk stratification, planning, awake and deep extubation and modifications aimed at reducing the risk of complications. An awake extubation is suitable for most patients but special techniques such as supraglottic airway exchange, remifentanil infusion or the use of an airway exchange catheter may be helpful in high-risk situations. Post-operative care does not end when the tracheal tube has been removed, handover and documentation are essential components of the extubation plan.
