目的探讨主动脉夹层全弓置换手术患者脑保护方法及护理要点。方法选取56例主动脉夹层全弓置换手术患者为研究对象,术前积极控制血压,术中采用深低温停循环、顺行性脑灌注、合理使用脑保护剂,术后积极纠正低氧血症、加强病情观察、维持内环境平衡。结果本组中,术后出现神经系统并发症15例(26.8%),2例并发多器官功能衰竭死亡,2例自动出院,52例患者治愈出院。结论主动脉夹层全弓置换术中选择灌注技术、有效的脑保护措施,围术期严密观察病情,有利于预防脑部并发症,促进患者顺利康复。 Objective To investigate the cerebral protection methods and nursing points of patients undergoing total aortic arch replacement. Methods Fifty-six patients undergoing total aortic dissection with total arch replacement were enrolled in this study. The blood pressure was controlled preoperatively. Deep hypothermic circulatory arrest and cerebral perfusion were used intraoperatively. Cerebrovascular protective agents were used rationally. Postoperative positive correction of hypoxemia , To strengthen the observation of the disease and maintain the balance of the internal environment. Results In this group, 15 patients (26.8%) had neurological complications after operation, 2 patients died of multiple organ failure, 2 patients were discharged automatically and 52 patients were cured. Conclusion Aortic dissection in the replacement of total bowel selection perfusion technique, effective brain protection measures perioperative strict observation of the disease, is conducive to the prevention of brain complications and promote the successful recovery of patients.
