Systematic literature review on early detection of postoperative delirium in adult patients after cardiac surgery.

Background: Postoperative delirium (POD) is a cognitive decline and attention deficit that can occur in patients after cardiac surgery. Despite extensive research identifying the risk factors, POD often remains undiagnosed and untreated in medical settings. Therefore, this systematic literature review (SLR) aimed to summarize the available studies on early POD identification in patients following cardiovascular surgery.

Association of postoperative delirium with hypotension in critically ill patients after cardiac surgery: a prospective observational study.

Background: Postoperative delirium (POD), an acute and variable disturbance in cognitive function, is an intricate and elusive phenomenon that occurs after cardiac surgery. Despite progress in surgical techniques and perioperative management, POD remains a formidable challenge, imposing a significant burden on patients, caregivers, and healthcare systems.

Methods: This prospective observational study involved 307 patients who underwent cardiac surgery.
