非心脏手术围手术期卒中危险因素的研究进展

围手术期卒中是非心脏手术的严重并发症之一，不仅可导致患者术后认知功能障碍，住院 时间延长及住院费用增加，还可增加致残率及病死率。研究表明，既往脑血管疾病、慢性心房颤动病 史及术后新发心房颤动、全身麻醉手术、血糖异常、β受体阻滞剂的使用等均可能为非心脏手术围手 术期卒中发生的危险因素。了解近期关于非心脏手术围手术期卒中危险因素的研究进展有助于临床 医师早期识别及控制相关危险因素，从而降低围手术期卒中风险，改善患者预后。

Progress of Risk Factors for Perioperative Stroke in Noncardiac Surgery

Perioperative stroke is one of the serious complications of noncardiac surgery. It can not only cause postoperative cognitive impairment, prolonged length of hospital stay and increased hospitalization costs, but also increase the disability rate and mortality. Recent studies have shown that the history of cerebrovascular disease, chronic atrial fibrillation and new-onset atrial fibrillation after surgery, general anesthesia, abnormal blood glucose, and the use of β blockers may be the risk factors for perioperative stroke in noncardiac surgery. This article reviewed the progress of these relevant risk factors, to help to timely identify and control these risk factors in noncardiac surgery, and reduce the risk of perioperative stroke and improve the prognosis of patients.
