Postoperative Cognitive Dysfunction in Participants Undergoing Open Heart Surgery

Postoperative delirium (POD) and Cognitive Dysfunction (POCD) are changes in mental status, especially in the geriatric surgery population.Unlike other forms of delirium, POD results in early full recovery.Postoperative Cognitive Dysfunction (POCD) is more difficult to define and implies temporal consciousness impairment associated with surgery.

While the diagnosis of delirium requires the detection of symptoms, the diagnosis of POCD requires preoperative neuropsychological testing and determining how much reduction will mean cognitive dysfunction. Postoperative delirium management is complex and requires multiple strategies. Methods of treating and preventing POCD are still uncertain.It is known that POCD is most commonly seen in patients undergoing open heart surgery.In this study, the investigators aim is to evaluate whether there is any change in cognitive status in the postoperative period compared to the preoperative period of participants who will undergo open heart surgery due to valve pathology or coronary stenosis.
