研究目的:

1.对比不同炎症表型ARDS患者,在入ICU基线期(T1)及炎症/代谢高峰期(T2,第3-5天)甲状腺功能关键指标(FT3、TSH)的水平与变化轨迹。 2.运用因果中介分析模型,定量检验甲状腺功能动态变化(以ΔFT3为核心中介变量)在“炎症表型”(自变量)与“ICU-AW发生及其特征”(因变量)之间的中介效应。 3.基于上述关联,初步构建并验证一个结合炎症标志物与甲状腺功能动态指标的ICU-AW早期风险预测列线图(Nomogram)。  

Objectives of Study:

1. To compare the levels and trajectories of the key indicators of thyroid function (FT3, TSH) in ARDS patients with different inflammatory phenotypes at baseline (T1) and peak inflammation/metabolism period (T2, day 3-5). 2. To quantitatively examine the mediating effect of dynamic changes in thyroid function (ΔFT3 as the core mediator variable) between inflammatory phenotype (independent variable) and ICU-AW occurrence and characteristics (dependent variable) by causal mediation analysis model. 3. Based on the above association, a Nomogram for early risk prediction of ICU-AW combined with inflammatory markers and thyroid function dynamic indicators was preliminarily constructed and verified.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.年龄 ≥ 18周岁和≤80岁; 2.符合《2023年急性呼吸窘迫综合征(ARDS)全球新定义》诊断标准; 3.需要有创机械通气; 4.直接从急诊、普通病房或外院(非ICU)转入本院ICU,或在其他医院ICU住院时间< 24小时即转入本院ICU者; 5.预计ICU住院时间≥ 72小时; 6.患者或其法定代理人签署书面知情同意书。

Inclusion criteria

1. Age >= 18 years old and <=80 years old; 2. The diagnostic criteria of acute respiratory distress syndrome (ARDS) were met by the 2023 New global definition. 3. Invasive mechanical ventilation is required; 4. Patients were transferred directly from the emergency department, general ward or other hospital (non-ICU), or transferred to the ICU of our hospital after staying in the ICU of other hospital for less than 24 hours; 5. The expected length of ICU stay was >= 72 hours; 6. Patients or their legal representatives provided written informed consent.

排除标准:

1.入ICU前已存在明确导致肌无力的疾病(如重症肌无力、脊髓损伤、脑卒中后严重偏瘫等); 2.既往有甲状腺疾病史(甲亢、甲减、甲状腺炎等)或近期(6个月内)使用影响甲状腺功能的药物(如胺碘酮、锂剂等); 3.严重外伤、烧伤或截肢导致肢体无法进行肌力评估; 4.长期卧床(>2周)或入院前即存在肢体功能障碍者; 5.本次住院期间或入院前4周内接受大型外科手术(尤其心胸外科、神经外科、骨科大手术),可能显著影响肌力评估或炎症反应者; 6.妊娠或哺乳期妇女; 7.临床医生判断生存期小于24小时或处于终末期状态。

Exclusion criteria:

1. Prior to ICU admission, patients had diseases that clearly caused muscle weakness (such as myasthenia gravis, spinal cord injury, severe hemiplegia after stroke, etc.). 2. Previous history of thyroid disease (hyperthyroidism, hypothyroidism, thyroiditis, etc.) or recent use (within 6 months) of drugs that affect thyroid function (such as amiodarone, lithium, etc.); 3. Severe trauma, burns, or amputation that prevents a limb from being assessed for muscle strength; 4. Long term bedridden (>2 weeks) or with limb dysfunction before admission; 5. Patients who underwent major surgery (especially cardiothoracic surgery, neurosurgery, orthopedic surgery) during or within 4 weeks before admission, which may significantly affect muscle strength assessment or inflammatory response; 6. Pregnant or lactating women; 7. Clinicians judged survival to be less than 24 hours or terminal.
