INCIDENCE OF Delirium After Cardiac SURGERY Surgery

Incidence And Predictors of Delirium After Cardiac Surgery; A Prospective Observational Cohort Study From a Single Tertiary Referral Centre

Delirium is a common problem that occurs after cardiac surgery. The incidence of delirium after cardiac surgery is estimated to be 26-52%, with a significant percentage being hypoactive delirium1-4.Postoperative delirium has been associated with higher hospital costs, longer lengths of hospital stay, increased likelihood of institutionalization, increased risk for dementia, and increased morbidity and mortality.5-7 .

The overall purpose of this study was to determine the incidence and perioperative factors that predispose to cause delirium in postoperative cardiac surgery patients in our ICU

Inclusion Criteria:

• Patients 18 years old and older of both sexes
• Patients who signed an informed consent
• Patients scheduled for cardiac surgery with extracorporeal circulation (coronary-artery bypass grafting (CABG), cardiac valve replacement (CVR), combined CABG + CVR, excision of cardiac myxoma)

Exclusion Criteria:

• Patients who refused to participate before or after operation;
