Anaesthesia and Postoperative Delirium
Postoperative delirium (POD) is the most common perioperative complication in the elderly, 12–51% experience this distressing complication after surgery. It is estimated that 30-40% cases of delirium are preventable. There is currently inconclusive evidence as to whether the type, duration, and depth of anaesthesia may influence the risk of developing POD. The use of processed EEG (pEEG) to monitor and target anaesthetic delivery to depth of anaesthesia have been examined as a plausible intervention to reduce POD. This presentation will discuss the evidence for perioperative interventions in reducing POD, with a focus on the use of pEEG-targeted general anaesthesia.
