研究目的:

1、主要目的: 评估在入住 ICU 早期呈现毛细血管渗漏优势表型的脓毒症患者中,在不可避免的早期液体正平衡复苏背景下,不同早期液体管理路径及去复苏速度是否与循环功能恢复轨迹存在系统性差异,重点分析其与入住 ICU 后前 7 天(day0-7)每日最大血管活性药物评分(VISmax)动态变化趋势之间的关联。 2、次要目的: (1)探讨早期液体管理路径及累积液体负荷水平与28天全因死亡率之间的关联,以验证主要结局的临床一致性; (2)探讨早期液体管理路径与其他器官功能相关结局 的关系,包括:28 天无呼吸机使用天数(反映呼吸功能恢复);入住ICU后7天内急性肾损伤(AKI)的发生或进展情况(依据 KDIGO-AKI 标准,作为液体负荷潜在系统性影响的安全性指标);ICU 住院时间(反映疾病恢复速度及医疗资源利用); (3)描述毛细血管渗漏优势表型患者入住ICU早期液体平衡的动态变化特征,并总结现实临床实践中已存在的、可识别且具有临床可解释性的液体管理路径。  

Objectives of Study:

1.Primary Objective: To evaluate whether, in septic patients exhibiting a predominant capillary leak phenotype during the early phase of ICU admission and undergoing unavoidable early positive fluid balance resuscitation, different early fluid management strategies and deresuscitation speeds are systematically associated with trajectories of circulatory recovery. The analysis will focus on the dynamic trends in daily maximum vasoactive-inotropic scores (VISmax) from ICU admission to day 7 (day 0–7). 2.Secondary Objectives: (1) To investigate the association between early fluid management strategies and cumulative fluid balance levels with 28-day all-cause mortality, thereby validating the clinical consistency of the primary outcome. (2) To explore the relationship between early fluid management strategies and other organ function-related outcomes, including: Ventilator-free days within 28 days (reflecting respiratory recovery); Incidence or progression of acute kidney injury (AKI) within the first 7 days of ICU admission (according to KDIGO-AKI criteria, as a safety indicator of potential systemic effects of fluid overload); ICU length of stay (reflecting speed of disease recovery and healthcare resource utilization). (3) To characterize the dynamic changes in early fluid balance among patients with the predominant capillary leak phenotype during ICU admission, and to summarize existing, identifiable, and clinically interpretable fluid management pathways observed in real-world clinical practice.
