Extubation & recovery
Also known as Extubation · Emergence · Laryngospasm · Post-extubation stridor · Airway exchange catheter · Staged extubation · Post-anaesthesia care unit · PACU
The extubation and the recovery are the high-risk phases of the anaesthetic that close the perioperative airway and the consciousness. The framework rests on the recognition of the extubation as the high-risk airway event (the DAS extubation guidelines), the extubation criteria, the awake versus the deep extubation, the extubation of the difficult airway (the planned, the staged, the airway-exchange-catheter, the leak test), the laryngospasm and the post-extubation stridor, the emergence and the emergence agitation, and the recovery-room (the PACU) management of the common complications (the PONV, the pain, the shivering, the hypoxaemia) and the discharge.

Meet the patient
A four-year-old is waking after a sevoflurane anaesthetic for hernia repair. He is thrashing, inconsolable, and not responding to his name; his parents are frightened. The monitor shows a normal saturation and a normal heart rate.[4]
This is emergence agitation, and the first job is to hold the reflex to sedate him and instead exclude the dangerous causes — hypoxia, pain, hypercapnia, a blocked airway — before reaching for a drug. Most of what goes wrong at the end of an anaesthetic is preventable by a planned extubation and a structured recovery, and that is what the topic is built to teach.[1]
