研究目的:

主要目的:验证头高位+静吸复合麻醉较传统方案提升术野清晰度的优效性(界值设定:Fromme量表改善≥1级) 次要目的:量化单位时间出血量差异(目标降低≥35%),评估血流动力学稳定性(MAP波动控制在±15%基线)。  

Objectives of Study:

Main objective: To verify the superiority of head high position combined with static inhalation anesthesia in improving surgical field clarity compared to traditional methods (threshold setting: Fromme scale improvement ≥ 1 level) Secondary objective: To quantify the difference in bleeding volume per unit time (target reduction ≥ 35%) and evaluate hemodynamic stability (MAP fluctuation controlled within ± 15% baseline).
