摘要心脏及大血管术后谵妄对患者预后影响甚大，包括住院时间延长、住院费用和再住院率增加等，发病率高达26%~52%。其发生为多因素综合作用的结果，包括术前（精神病史及认知功能障碍、脑血管病史、高龄及心功能不全等）、术中（手术时间>5 h、急诊手术、术中心肌损伤及麻醉药物使用等）和术后（疼痛、睡眠障碍、深度镇静、机械通气时间>72 h等）的因素。为规范其管理，中国医疗保健国际交流促进会心脏重症分会结合国内外研究结果和多位专家的临床经验，在充分讨论和沟通的基础上制订了“心脏及大血管术后谵妄的防治中国专家共识”，为我国心脏及大血管术后谵妄诊治及预防提供规范化的标准，以期减少我国在心脏及大血管外科术后谵妄的发生和获得更好的预后。

abstractsPostoperative delirium of cardiovascular surgery occurs in up to 26%-52% of patients after cardiovascular surgery and is associated with adverse outcomes, including increased hospital length of stay, higher cost of care, higher rates of readmission. The combination of multiple factors leads to postoperative delirium of cardiovascular surgery, including preoperative (previous psychiatric conditions and cognitive disfunction, cerebrovascular disease, age, cardiac insufficiency, and so on), intraoperative (duration of surgery>5 h, emergency surgery, anesthetic drugs, direct myocardial injury, and so on) and postoperative (pain, sleep disturbance, Deep sedation, duration of mechanical ventilation>72 h) risk factors. On the basis of the latest literature at home and abroad and the clinical experience of many experts, the Cardiac Critical Care Branch of China International Exchange and Promotive Association for Medical and Health sought to develop a consensus document"Chinese expert consensus on the prevention and treatment of postoperative delirium of cardiovascular surgery", in order to standardize the management of postoperative delirium of cardiovascular surgery and improve the prognosis of patients.
