医院手术室随机氧气 (HOT-ROX) 试验可行性阶段证实,可以安全地使用不同的术后氧气治疗方案. 这些发现支持了临床试验的结论.
科学领域:
- 麻醉学和外科手术期间的医学.
- 关键护理医学 关键护理医学
- 手术部位感染的预防 手术部位感染的预防
背景情况:
- 国际指导方针建议在全身麻醉期间给予自由氧气,以减少手术部位感染.
- 最佳的术后氧气策略,以尽量减少术后并发症和增强手术恢复仍然不清楚.
- 医院手术室随机化氧 (HOT-ROX) 试验调查了受限制,标准和自由氧方案的影响.
研究的目的:
- 报告HOT-ROX试验内部先阶段的可行性和安全性调查结果.
- 评估不同术前氧气治疗策略的协议实施和安全终点.
- 确定进行完整多中心随机临床试验的可行性.
主要方法:
- 一个多中心,患者和评估者盲目,并行组,随机临床试验先阶段.
- 包括210名在澳大利亚和新西兰四家医院进行全身麻醉的长期非心脏手术的成年患者.
- 限定的标准护理或自由的术前氧气疗法,预先指定可行性和安全性终点.
主要成果:
- 成功地实施了不同的手术内吸入氧气 (FiO2) 水平:受限 (0.30),标准护理 (0.47) 和自由 (0.83).
- 所有八个预先规定的可行性终点都实现了,证明了有效的协议实施.
- 没有报告患者显著的不良事件,这表明所有疗法都具有有利的安全性.
结论:
- 在HOT-ROX试验的先可行性阶段,成功地证明了有限,标准和自由的周围操作氧气的安全性和可行性.
- 这些数据强烈支持在不进行重大协议修改的情况下继续进行完整的HOT-ROX试验.
- 这项可行性研究为在重大手术期间对最佳氧气治疗进行明确研究铺平了道路.
