研究目的:

本研究拟开展一项多中心、前瞻性、观察性研究,旨在构建并验证一种基于EIT参数的ARDS预后模型,期望从ARDS的病理生理特点和呼吸机相关肺损伤的根本原因出发,建立能充分反映肺损伤和异质性的ARDS的预后模型,实现风险分层和个体化治疗指导。  

Objectives of Study:

This multicenter, prospective, observational study aims to develop and validate an ARDS prognostic model based on EIT (Electrical Impedance Tomography) parameters. By focusing on the pathophysiological characteristics of ARDS and the underlying mechanisms of ventilator-induced lung injury (VILI), we seek to establish a prognostic model that accurately reflects lung injury and heterogeneity, enabling risk stratification and guiding personalized treatment.

测量指标:

Outcomes:

指标中文名:

28天病死率

指标类型:

主要指标

Outcome:

28-day mortality

Type:

Primary indicator

测量时间点:

从入组至第28天的死亡率

测量方法:

通过医院信息系统及入组后第28天进行的电话随访,收集患者的生存状态数据

Measure time point of outcome:

28-day mortality from diagnosis

Measure method:

Data on vital status were collected through hospital information systems and follow-up telephone interviews conducted on Day 28 post-diagnosis

指标中文名:

ICU病死率

指标类型:

次要指标

Outcome:

ICU Mortality

Type:

Secondary indicator

测量时间点:

从入住ICU至转出ICU或死亡的时间段内

测量方法:

计算在ICU住院期间发生的全因死亡。分母为纳入分析的ICU患者总数。存活转出ICU的患者不计入ICU病死率。

Measure time point of outcome:

During ICU stay (from ICU admission to ICU discharge or death)

Measure method:

Calculated as the proportion of patients who died from any cause during their ICU stay. Patients discharged alive from the ICU are not counted as ICU deaths.

指标中文名:

Outcome:

90-day Mortality

Type:

Secondary indicator

Measure method:

All-cause mortality within 90 days.

Type:

Secondary indicator

测量时间点:

从入组开始计算,截至第28天

测量方法:

计算方法:如果患者在28天内成功脱机拔管且存活,则无呼吸机天数 = 28 - 机械通气天数。如果患者在28天内死亡或持续依赖呼吸机超过28天,则无呼吸机天数计为 0。如果患者在28天内脱机后又再次插管,则机械通气天数需累计计算。

Measure time point of outcome:

Within the first 28 days from Enrollment

Measure method:

Calculation method: if the patient successfully extubated within 28 days and survived, the days without ventilator=28- days with mechanical ventilation. If the patient dies within 28 days or continues to rely on ventilator for more than 28 days, the number of days without ventilator is 0. If the patient is weaned and intubated again within 28 days, the days of mechanical ventilation should be calculated cumulatively.
