研究目的:

本研究是旨在探讨在接受腰硬联合阻滞下髋膝关节置换术的老年人群中,在麻醉开始前应用右美托咪定鼻喷剂能否通过降低神经炎症反应从而降低术后谵妄的发生。从而提高我们对术后谵妄的认知,从而为患者提供更优质的围术期管理策略并改善患者的生存质量。  

Objectives of Study:

The aim of this study is to investigate whether dexmedetomidine nasal spray before anesthesia could reduce the incidence of postoperative delirium in elderly patients undergoing hip and knee replacement under combined spinal-epidural block by reducing neuroinflammatory response. It could improve our understanding the postoperative of postoperative delirium, so as to provide patients with better perioperative management strategies and improve the quality of life of patients.
