研究目的:

本研究拟明确,与平原人群相比,高海拔暴露史是否增加全麻下行下肢关节手术患者术后谵妄发生风险。  

Objectives of Study:

This study aims to determine whether a history of exposure to high altitude increases the risk of postoperative delirium(POD) in patients undergoing lower limb joint surgery under general anesthesia compared with the patients from plain ereas.

药物成份或治疗方案详述:

根据是否存在长时间高海拔暴露,有长时间高海拔暴露者为高海拔暴露组。高海拔暴露的定义:世居(从出生起就生活在高海拔地区)或移居(≥20年)高原(≥2500 m)者,且手术前在平原地区(≤500 m)连续生活不超过180天。 根据是否存在长时间高海拔暴露,无长时间高海拔暴露者为无高海拔暴露组。 

Description for medicine or protocol of treatment in detail:

The high-altitude group has prolonged high-altitude exposure. Prolonged high-altitude exposure in this study is defined as Tibetan highlanders (for having lived at high altitudes since birth) or Tibetan settlers living at high-altitudes (altitude≥2500 meters) for more than 20 years, and without living continuously in plain area (≤500m) for more than 180 days before surgery. Based on whether there was prolonged high-altitude exposure, the non high-altitude group doesn't have prolonged high-altitude exposure.
