COMPLICATION
Postoperative delirium (POD) is a serious complication characterized by an acute mental change and fluctuation in attention and cognitive function. POD can result in chronic deterioration of the cognitive functions, postoperative cognitive dysfunction (POCD), and is also associated with increased postoperative morbidity, institutionalization and mortality [Even though perception and integration of information during anaesthesia are supposed to be turned off, yet, various observations suggest that auditory information processing is potentially intact [Here, we examined the effects of intraoperative positive suggestions applied via headset on the development of POD in aged patients who underwent TAVR under general anaesthesia. Additionally, we evaluated the effect on postoperative pain and nausea and vomiting (PONV).
