Abstract:
Objective To observe and analyze the morbidity and risk factors of postoperative delirium in the patients un-dergoing cardiac surgery.Methods From March 2017 to March 2018, 478 patients who need cardiac surgery were selected from our hospital.According to the postoperative results evaluated with Confusion Assessment Method(CAM), they were divid-ed into delirium group(54 patients)and control group(424 patients).Morbidity and risk factors of postoperative delirium were analyzed.Results Delirium occurred in 54 patients of 478 patients and morbidity of postoperative delirium was 11.3％.Psy-chomotor excitement is the most common clinical presentations , followed by attention impairment and a reduced level of con-sciousnes.Single factor analysis result showed that delirium was associated with advanced age (≥65 years) , hypertension, pre-vious cerebral vascular event(previous cerebral infarction, previous brain heamorhage), intraoperative blood loss, mechanical ventilation time, intensive care unit duration time.The multiple-logistic regression analysis indicated that the perioperative risk factors of delirium included advanced age, cerebrovascular accident history and ICU duration time.Conclusion The patients with advanced age, hypertension, previous cerebral vascular event(previous cerebral infarction, previous brain heamorhage) are the high risk groups for delirium after cardiac surgery.Advanced age, hypertension, previous cerebral vascular event(previ-ous cerebral infarction, previous brain heamorhage) are risk factors for delirium in patients undergoing cardiac surgery.
