Delirium is a temporary neuropsychiatric syndrome that is common after heart surgery. Despite its high prevalence in elderly and in intensive care, it is often not recognized by clinics or is seen as unpredictable important complications of critical diseases such as depression, intensive care syndrome, dementia. The aim of our study is to identify the risk factors associated with prevalence and delirium in patients aged 65 and over in an intensive care unit after open heart surgery. The study included 217 patients aged 65 and over. The data were collected by measuring the confusion assessment scale in the intensive care unit (CAMICU) [The Confusion Assessment Method for the In-tensive Care Unit (CAMICU)] and all other psychiatric diagnoses that are the golden standard in the definition of delirium, according to the international guide, Diagnostic and Statistical Manual for Mental Disorders (DSM-IV). The study found the prevalence of delyroid at 29.5%. Advanced age, male sex, high acute physiology and chronic health evaluation II (APACHE II), New York heart association functional classification (NYHA)>2, cerebrovascular disease, poor physical condition, aortic surgery, duration of surgery, time of scemic, low hematocritity (<30), increased blood laktate levels (>1,2mmol/L), hypoalbuminemia (<3g/dL), increased BUN/creatine ratio (>18), immobilization, postoperative 48 hours of medication, sleep disorder and intensive maintenance period were identified as risk factors in the development of delusion in the elderly. Delirium is a multifactoral disease that is observed in elderly patients after open heart surgery. Identification and control of risk factors reduces the duration of hospitalization and departure, morbidity and mortality.
