研究目的:

应用 CT 影像组学联合 LUS 识别重症肺炎 ARDS 患者临床分型;评估不同液体管理策略对重症肺炎 ARDS 临床亚型患者预后的影响并基于影像组学和 LUS 的制定重症肺炎 ARDS 患者个体化液体管理策略。  

Objectives of Study:

Applying CT radiomics combined with lung ultrasound (LUS) to identify clinical subtypes of ARDS in patients with severe pneumonia; evaluating the impact of different fluid management strategies on the prognosis of ARDS clinical subtypes in severe pneumonia patients; and formulating individualised fluid management strategies for ARDS patients with severe pneumonia based on radiomics and LUS.

LUS肺水肿相关数据

指标类型:

主要指标

Outcome:

LUS pulmonary oedema-related data

Type:

Primary indicator

测量时间点:

第1/3/7/14/28天

测量方法:

将超声机设定为肺部模式,选择凸阵探头分别扫查双侧前胸部、侧胸壁和后胸壁的深层肺组织,观察肺部“A线”、“B线”及“C征象”情况。根据这6个部位的肺部超声情况得出肺水评分

Measure time point of outcome:

Days 1/3/7/14/28

Measure method:

Set the ultrasound machine to lung mode. Using a convex array probe, scan the deep lung tissue in the bilateral anterior chest, lateral chest wall, and posterior chest wall. Observe the presence of ‘A lines’, ‘B lines’, and ‘C signs’ in the lungs. Derive the pulmonary oedema score based on the ultrasound findings in these six regions.
