- First-time admission to the Intensive Care Unit (ICU)
- Diagnosis of sepsis according to Sepsis-3.0 criteria (documented or clinically suspected infection plus Sequential Organ Failure Assessment [SOFA] score ≥2 points)
- Expected ICU survival time ≥24 hours
- Written informed consent provided by the patient or legal surrogate
Exclusion Criteria:
- Pregnancy or lactation
- Cardiopulmonary-cerebral resuscitation (CPCR) performed during the current hospital admission

设计细节
队列和干预
团体/队列 |
干预/治疗 |
|---|---|
|
High Inflammatory Phenotype Group
Septic patients displaying serum Interleukin-6 (IL-6) ≥ 400 pg/mL upon ICU admission (Day 1) .
|
Standard sepsis bundle treatment + 72-hour quantitative continuous EEG monitoring + structured long-term cognitive follow-up.
|
|
Low Inflammatory Phenotype Group
Septic patients displaying serum Interleukin-6 (IL-6) < 400 pg/mL upon ICU admission (Day 1) .
|
Standard sepsis bundle treatment + 72-hour quantitative continuous EEG monitoring + structured long-term cognitive follow-up.

研究衡量的是什么?
主要结果指标
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Quantified EEG Features and Young Classification Grade
大体时间:72 hours after enrollment
|
Description: Power spectral density (delta, theta, alpha, beta frequency bands), relative delta band power ratio (1-4 Hz), epileptiform discharge frequency, burst-suppression ratio, and Young EEG grading (Grade I to VI, double-blinded expert consensus reading).
|
72 hours after enrollment
|
|
Favorable Neurological Prognosis Rate (CPC Score)
大体时间:Baseline (Day 1), Day 2, Day 3, Day 7, Day 30, Day 90, and Day 180 post-enrollment.
|
Neurological outcome assessed using the Cerebral Performance Category (CPC) scale.
The CPC score ranges from 1 to 5, with lower scores indicating better neurological function.
CPC scores of 1-2 indicate favorable neurological outcomes, whereas CPC scores of 3-5 indicate unfavorable neurological outcomes.
|
Baseline (Day 1), Day 2, Day 3, Day 7, Day 30, Day 90, and Day 180 post-enrollment.
|
次要结果测量
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Montreal Cognitive Assessment (MoCA) Score
大体时间:Baseline (Day 1), Day 2, Day 3, Day 7, Day 30, Day 90, and Day 180 post-enrollment.
|
Cognitive function assessed using the Montreal Cognitive Assessment (MoCA) scale.
The total MoCA score ranges from 0 to 30, with higher scores indicating better cognitive function.
A MoCA score <26 is defined as cognitive impairment.
|
Baseline (Day 1), Day 2, Day 3, Day 7, Day 30, Day 90, and Day 180 post-enrollment.
|
|
Mortality
大体时间:Day 30, Day 90, and Day 180 post-enrollment.
|
All-cause mortality collected through electronic medical records and structured telephone follow-up.
|
Day 30, Day 90, and Day 180 post-enrollment.
|
|
Length of ICU Stay
大体时间:Up to 180 days post-enrollment.
|
Total duration of stay in the Intensive Care Unit in days.
|
Up to 180 days post-enrollment.
|
|
Health-Related Quality of Life (EQ-5D-5L Index)
大体时间:Day 30, Day 90, and Day 180 post-enrollment.
|
Health-related quality of life assessed using the EuroQol 5-Dimension 5-Level (EQ-5D-5L) Index.
The EQ-5D-5L index score ranges from -0.594 to 1.000, with higher scores indicating better health-related quality of life.
|
Day 30, Day 90, and Day 180 post-enrollment.
