像Maquet Flow-i C20 (MQ) 这样的低容量麻醉机器,比传统的机器 (GE Aisys CS2) 减少了大约20%的sevoflurane. 这提高了麻醉剂的输送效率,提供了显著的经济和环境效益.
科学领域:
- 麻醉学 麻醉学
- 医疗器械 医疗器械
- 卫生经济学 卫生经济学
背景情况:
- 低容量麻醉机具有减少电路容量和针注射蒸发器,以更有效地输送挥发性剂.
- 传统的麻醉器使用不同的电路设计和麻醉剂的蒸发方法.
研究的目的:
- 为了比较Maquet Flow-i C20 (MQ) 低容量麻醉工作站与GE Aisys CS2 (GE) 传统麻醉机器的挥发性麻醉剂传递效率.
- 评估与任何观察到的麻醉剂消耗差异相关的潜在经济和环境益处.
主要方法:
- 一项涉及103名成人患者的比较研究,这些患者接受了用sevoflurane进行全身麻醉.
- 在诱导和维护阶段测量了sevoflurane的消耗和输送率.
- 使用单面参数测试 (学生的t测试) 的统计分析用于比较两个麻醉器组.
主要成果:
- 与GE组 (118.3 ± 62.4 g) 相比,MQ组的消耗量显著降低 (95.5 ± 49.3 g),相当于效率提高了约20% (p = 0.043).
- 该MQ以显著较低的速率 (7.4 ± 3.2L/分钟) 输送挥发性物质,而不是GE (9.1 ± 4.1L/分钟) (p = 0.017).
- 预计MQ将在10年内节省239,440美元,并减少201公二氧化碳相当的排放量.
结论:
- 与GE Aisys CS2 (GE) 相比,Maquet Flow-i C20 (MQ) 在例行选择性手术中显著减少了约20%的挥发性麻醉剂的使用.
- 这种提高效率转化为大幅度的经济节约和环境影响的显著减少.
- 标准化协议和患者选择将异质性降到最低,加强观察到的效率增长的有效性.
