在麻醉诱导期间,头部旋转的口罩通风并没有改善左肺通风,但增加了呼气潮体积. 这种头部位置可以提供更好的氧化,尽管没有改变肺透气分布.
科学领域:
- 麻醉学 麻醉学
- 呼吸系统生理学 呼吸系统生理学
- 医疗成像医学成像
背景情况:
- 在麻醉诱导期间,异常的区域肺通风是令人担忧的.
- 头部旋转通风可以改变上呼吸道的空气流量,增加潮体积.
研究的目的:
- 为了研究头部旋转口罩通风对麻醉诱导期间区域肺通风分布的影响.
- 为了比较中性和旋转头部位置之间的通风分布.
主要方法:
- 90名患者被随机分配到中立头或旋转头罩通风组.
- 电阻断层扫描监测了区域性肺呼吸.
- 主要结局:左/右肺通风比;次要结局:全球不均指数 (GI) 和通风中心 (CoV).
主要成果:
- 面具通风显著改变了左/右肺通风比,并将通风转移到腹肺区域,增加了不均性.
- 在中性和旋转头组之间,左/右肺通风率没有显著差异.
- 与中性头相比,旋转头罩通风与更高的呼气潮流体积 (TVe) 有关.
结论:
- 面罩正压通风改变了区域肺通风分布.
- 头部旋转的口罩通风并没有改善左肺通风,但增加了TVe,可能改善了氧化.
- 需要进一步的研究来探索这些发现的临床影响.
