高风险机械通风患者在肺超声波上具有局部组织样模式 (TLP),与分散的B线 (DBP) 患者相比,对管理的反应更好,奶结果类似. 肺部形态学有助于定制策略和预测结果.
科学领域:
- 关键护理医学 关键护理医学
- 肺部病理学 肺部病理学
- 诊断成像 诊断成像 诊断成像
背景情况:
- 在高风险患者中,机械通风断奶带来了挑战.
- 肺部超声波 (LUS) 可以识别不同的形态模式:局部组织样模式 (TLP) 和分散的B线 (DBP).
- 这些LUS模式与管理响应和断奶结果的临床意义尚未完全阐明.
研究的目的:
- 调查LUS形态模式 (TLP与DBP) 与患者对断奶期间临床医生指导的例行管理的反应之间的关联.
- 评估这些模式对高风险机械通风患者的肺再通气,断奶成功和其他临床结果的影响.
主要方法:
- 对97名高风险机械通风患者的回顾性研究,肺部超声波得分 (LUS) > 13.
- 患者根据LUS形态分为TLP和DBP组.
- 干预前后通过肺部招募得分 (LRS) 评估肺部重新通气;结果包括LRS变化,断奶失败,通风持续时间,ICU死亡率和停留时间.
主要成果:
- 与DBP组相比,TLP组的初始全球LUS较高 (17.20 ± 2.01与14.21 ± 2.04相比,P < 0.001).
- 在TLP组中,干预后的全球LRS显著改善 (5.43 ± 3.42对比4.04 ± 2.99,P = 0.036),表明肺部再空气化更好.
- 阿帕奇II分数和全球LRS是断奶失败的独立预测因素;在成功断奶的患者中,TLP患者的LRS较高 (6.71 ± 2.31对比5.39 ± 2.26,P = 0.021).
结论:
- 患有TLP的患者对常规管理表现出更好的反应,并与DBP患者取得了与DBP患者相似的断奶结果,尽管初始LUS.US更高.
- 肺形态模式 (TLP与DBP) 和区域LRS评估可以帮助量身定制管理策略.
- 这些LUS发现可能有助于预测高风险机械通风患者的断奶结果.
