    The incidence of postoperative delirium (POD) in ICU patients after cardiac surgery with extracorporeal circulation is 28.15%.

  • 2

    Key risk factors for POD include older age, longer mechanical ventilation time, higher APACHE II score, and lower albumin levels.

  • 3

    Patients in the POD group had significantly higher APACHE II scores and longer aortic cross-clamping and cardiopulmonary bypass times.

  • 4

    ICU nursing records effectively identify high-risk patients for POD, aiding in early warning and risk stratification.

  • 5

    The study highlights the need for comprehensive analysis of influencing factors on POD in patients undergoing cardiac surgery.
