Abstract :Internal carotid artery stenosis is a consequence of systemic atherosclerotic disease. Internal carotid artery endarterectomy is a treatment method used to prevent life-threatening strokes in patients with severe internal carotid artery stenosis. Delirium may occur in patients after carotid endarterectomy due to hemodynamic changes due to cerebral perfusion deficiency. This study was conducted to determine the frequency and risk factors of delirium in patients who undergoing carotid endarterectomy. The research was a descriptive and cross-sectional prospective study. Research data were collected in 2 years and 83 patients who agreed to participate in the study were reached. Sociodemographic and clinical characteristics data collection form, intensive care delirium screening checklist, and pain scale were used. Delirium was detected in 2.07% of the patients after carotid endarterectomy. The mean oxygen saturation values of the patients with and without delirium in the 2-4 hours after carotid endarterectomy were found to be a statistically significant difference (p<0.05). After carotid endarterectomy oxygen saturation means of the patients who developed delirium was lower than the other patients in the 2-4 hours postoperatively. In patients who sleep 4 hours or more, delirium was less common than other patients. It was found that the means pain scores of patients who developed and did not develop delirium on the 1st postoperative day were statistically significant (p<0.05) In conclusion, after internal carotid artery endarterectomy, advanced age, low arterial partial oxygen pressure and oxygen saturation, presence of postoperative pain and short sleep duration are risk factors for delirium.
