Final answer:
The time frame of emergence delirium, post op delirium, and post op cognitive dysfunction varies from minutes to months after surgery.
Step-by-step explanation:
The time frame of emergence delirium is typically within minutes to hours after emerging from anesthesia. It is a transient state of confusion and agitation that can occur in the post-anesthetic period. Postoperative delirium, on the other hand, occurs within a few days after surgery and is characterized by a fluctuating state of confusion, disorientation, and altered consciousness. Postoperative cognitive dysfunction refers to a decline in cognitive function that can last for weeks to months after surgery, and may manifest as memory impairment, attention deficits, and difficulty with problem-solving.
