研究目的:

1.评估控制性降压相较于常规血压管理在减少高原骨科手术患者术中失血量及输血需求方面的有效性(血液保护效应); 2.评估控制性降压在高原骨科手术中实施时,对患者围术期器官灌注安全性的影响,重点监测尿量及动脉血乳酸水平的变化,并观察相关并发症发生情况; 3.探索在保障器官灌注安全(基于尿量和动脉血乳酸水平)的前提下,高原骨科手术中实施控制性降压以达到最佳血液保护效果的平均动脉压(MAP)安全目标范围。  

Objectives of Study:

1. Evaluate the effectiveness of controlled hypotension compared to conventional blood pressure management in reducing intraoperative blood loss and transfusion needs in patients undergoing high-altitude orthopedic surgery (blood protective effect); 2. Evaluate the impact of controlled hypotension on the safety of perioperative organ perfusion in patients undergoing high-altitude orthopedic surgery, with a focus on monitoring changes in urine output and arterial blood lactate levels, and observing the occurrence of related complications; 3. Explore the safe target range of mean arterial pressure (MAP) for implementing controlled hypotension in high-altitude orthopedic surgery to achieve optimal blood protection while ensuring organ perfusion safety (based on urine volume and arterial blood lactate levels).
