Stages of General Anesthesia01:22

Stages of General Anesthesia

689
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

科学领域:

  • 心脏病学
  • 神经学
  • 麻醉学

背景情况:

  • 心内回声扫描 (ICE) 是治疗左心房塞 (LAAO) 的一种转食管回声扫描的替代方案.
  • 在接受LAAO的老年患者中,全身麻醉可能导致认知障碍.

研究的目的:

  • 研究麻醉方法 (GA与中度镇静 (MS)) 对接受LAAO患者的认知功能的影响.
  • 使用一种新的数字眼动生物标志物来评估认知变化.

主要方法:

  • 在两个中心 (GA和MS) 招收接受LAAO的患者.
  • 使用ViewMind系统 (眼睛追踪) 评估的认知功能在治疗开始时,在治疗后6小时和45天.
  • 眼动测试 (Go/No Go,N-Back) 评估了群体内部和群体之间的认知差异.

主要成果:

  • 患有多发性硬化症的患者在工作记忆,处理速度和持续注意力方面显著改善 (N-Back任务).
  • 在研究期间,GA组中没有观察到显著的认知差异.
  • 40名患者 (每组20名) 完成了该研究.

结论:

  • 在MS组中,与记忆相关的眼运动指标在LAAO后有所改善,但不是GA组.
  • 在接受LAAO的老年患者中,镇静策略似乎对认知功能有不同的影响.
  • 这项研究为使用眼运动生物标志物评估LAAO麻醉的认知效应提供了概念证明.
