emergence delirium
Postoperative behavioral disturbance characterized by agitation, disorientation, and inconsolability, particularly common in preschool children recovering from sevoflurane anesthesia.
Full Definition
Emergence delirium, also known as emergence agitation, is a postoperative complication characterized by mental confusion, irritability, disorientation, and thrashing movements during emergence from general anesthesia. This phenomenon is particularly prevalent in pediatric patients aged 2-5 years and occurs most frequently after sevoflurane anesthesia. The condition typically presents within the first 30 minutes of emergence and can be distinguished from pain by its lack of response to analgesics and the presence of disorientation. Risk factors include rapid emergence, certain surgical procedures (ENT, ophthalmologic), and the child's temperament.
Usage
Usage note: Distinguish clearly from postoperative pain in documentation. Both terms (emergence delirium and emergence agitation) are acceptable.
