The Clinical Characteristics And Related Risk Factors Of Type-A Aortic Dissection Postoperative Delirium State

Objective:This study explored differences in patient outcomes from delirium and non-delirium analyzed in terms of aortic dissection postoperative delirium risk factors, the characteristics of the specific circumstances of patients after the implementation of aortic dissection surgery delirium were summarized and analyzed, providing preventive mechanisms and proper diagnosis and treatment of postoperative delirium in the future.Methods:Patients choose to take the January 2013 to December 2015 the Court received the past three years in Type-A aortic dissection surgery a total of 80 cases of observation group. Respectively, in the first days before and after surgery in patients with peripheral blood sample specimen hypersensitive C-reactive protein (C-RP) and erythrocyte sedimentation rate (ESR), and cortisol concentrations were detected. Patients with postoperative delirium symptoms using a standard scale Chinese (DSM-Ⅳ)delirium evaluated. Use SPSS 17.0 software during the assessment of the risk factors for technical inspection. The two groups of patients were compared, combined with detailed patient clinical data to explore the related risk factors for delirium, confusion and evaluated against the patient’s consciousness, for conduct delirium diagnosis.Result:After aortic dissection surgery is completed, a total of 26 patients with postoperative delirium, the rate was 32.50%. Among them,20 cases (76.92%) patients were diagnosed with transient delirium (duration within one day); 6 cases (23.08%) patients were diagnosed with delirium persistent (lasting more than 24 hours). The analysis summary, operation time, duration of mechanical ventilation, duration, deep hypothermic circulatory arrest time is too long, there is a history of cerebral infarction, abnormal oxygen saturation and so is a major risk factor leading to delirium.Conclusion:For patients after aortic dissection surgery, reducing its operation time, duration of mechanical ventilation, duration, reducing DHCA time, pay attention to the oxygen saturation controls to reduce the risk of patients with postoperative delirium. After more research on the clinical features of patients with aortic dissection postoperative delirium, delirium risk factors found mainly:old. Older patients are more prone to arterial dissection cases of postoperative delirium; high intensity stress response. Since patients receiving high intensity of stimulation, the stress response can cause delirium in patients after arterial dissection, effectively inhibit the stress response may occur in patients with aortic dissection cases of postoperative delirium may act to reduce the role.
