QUIZ #2 – APM

Anaesthesia and postoperative delirium

Correct Answer: C

Explanation: Excessively deep anaesthesia (especially in the elderly) is associated with increased risk of postoperative delirium. EEG-guided depth of anaesthesia monitoring helps reduce delirium incidence. Benzodiazepines and high-dose opioids increase the risk of postoperative delirium (Reference: Sumner M, Deng C, Evered L, Frampton C, Leslie K, Short T, Campbell D.
