背景情况:

在需要V-V ECMO的严重ARDS患者中调查异质性至关重要.
之前的研究没有在这个特定的患者群体中探索亚表型.
亚表型可能有助于量身定制治疗和预测结果.

研究的目的:

为了确定接受V-V ECMO的严重ARDS患者的不同亚现象.
分析已识别的子类型与死亡率之间的关系.
为了确定PEEP设置是否会在各个子类型中对结果产生不同的影响.

主要方法:

在V-V ECMO上对544名严重ARDS的成年患者进行了回顾性多中心观察性研究.
隐性类分析 (LCA) 用于基于初步放射学和临床发现的亚表型识别.
多变量考克斯回归分析了死亡率差异和PEEP与子类型结果的相关性.

主要成果:

确定了三个亚现象型:干 (34%),湿 (31%) 和纤维 (35%).
与干燥和湿燥类型相比,纤维化类型的90天住院死亡率明显高.
在早期ECMO中更高的PEEP (≥10cmH2O) 仅在湿型中降低了死亡率,具有显著的相互作用效应 (p=0.036).

结论:

在V-V ECMO上,严重ARDS的不同亚表型显示出不同的死亡风险.
早期高PEEP对死亡率的影响在这些亚表型中显著不同.
基于临床亚现象型的V-V ECMO治疗严重ARDS患者的个性化治疗策略是合理的.

Acute Respiratory Failure-II

Acute Respiratory Failure-II

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Acute Respiratory Failure-I

Acute Respiratory Failure-I

Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
