How long does post-operative cognitive dysfunction last?

Post-operative cognitive dysfunction (POCD) is a state in which a patient’s memory and learning decline after surgery. POCD is common: 1 in 3 patients will have POCD at discharge. 1 in 10 patients will have POCD that lasts up to three months after surgery.

What are the three types of delirium?

What is the most common cause of post operative hypoxemia?

The majority of postoperative hypoxemia is from pulmonary dysfunction, which includes causes from shunted and nonshunted physiology. In the immediate postoperative period, other common causes of hypoxemia are bleeding and hypovolemia. Cardiacinduced pulmonary dysfunction can also lead to significant hypoxemia.

Can surgery bring on dementia?

Studies in people They found that general anaesthesia was associated with higher risks of dementia.
