研究目的:

1 主要目的 探讨术中低体温负荷与老年髋关节置换术患者低体温相关PACU恢复不良结局之间的关系。 2 次要目的 (1)描述老年髋关节置换术患者术中鼻咽温动态变化轨迹; (2)分析术中低体温负荷与PACU停留时间延长、中重度寒战、PACU出室低体温及额外复温干预之间的关系; (3)探索术中低体温负荷与低体温相关PACU恢复不良风险之间是否存在剂量-反应关系及潜在风险阈值; (4)比较低体温负荷、最低鼻咽温及低体温持续时间对低体温相关PACU恢复不良复合结局的预测效能。  

Objectives of Study:

1. Primary ObjectiveTo investigate the relationship between intraoperative hypothermia load and poor PACU recovery outcomes related to hypothermia in elderly patients undergoing hip arthroplasty.2. Secondary Objectives(1) Describe the dynamic trajectory of nasopharyngeal temperature changes during surgery in elderly hip arthroplasty patients;(2) Analyze the relationship between intraoperative hypothermia load and extended PACU stay, moderate to severe shivering, hypothermia on PACU discharge, and additional rewarming interventions;(3) Explore whether there is a dose-response relationship and potential risk threshold between intraoperative hypothermia load and hypothermia-related poor PACU recovery outcomes;(4) Compare the predictive efficacy of hypothermia load, minimum nasopharyngeal temperature, and duration of hypothermia for composite outcomes of hypothermia-related poor PACU recovery.
