老年患者术后谵妄的研究进展

Research progress on postoperative delirium in elderly patients

术后谵妄(POD)是手术后一种常见的急性中枢神经系统综合征。由于生理机能的减退,老年人较儿童和成年人更易发生POD,且POD严重影响着老年患者的术后转归。随着社会的老龄化,老年患者手术量每年递增,POD的临床研究已成为麻醉学领域的热点问题之一。本文从风险预测、预后评估、预防策略、治疗方案4个方向对POD的临床研究进展进行综述,以期为老年POD的临床防治工作提供依据。

Postoperative delirium(POD)is a common acute central nervous system syndrome after surgery.Due to the physiological degeneration,POD occurs more frequently among the elderly patients than among the children and adults and has serious impact on their postoperative outcomes.The population aging and the increasing annual volume of procedurals performed on the elderly patients have caused POD to become one of the most popular issues in the field of anesthesiology.In this article,we reviewed the recent clinical studies on POD in four respects:risk prediction,prognosis assessment,prevention strategies and treatment protocols,with a view to providing a basis for its clinical prevention and treatment among the elderly.
