Study design:

Cohort study 

研究目的:

1.建立一种基于多组学肠道菌群鉴定分析的SAE诊断预测系统; 2.通过对肠道菌群的表达差异分析,建立针对SAE不同临床表型的分型鉴定标准。  

Objectives of Study:

1. Establish a SAE diagnosis and prediction system based on the identification and analysis of intestinal flora by multi-omics analysis; 2. Through the analysis of the expression difference of intestinal flora, establish the typing identification standard for different clinical phenotypes of SAE.

纳入标准:

脓毒症患者:符合“2016年危重病医学会/欧洲危重病医学会/美国胸科医师协会/美国胸科学会/外科感染学会关于全身性感染定义国际会议”所制定的脓毒症3.0诊断标准, 其定义为宿主对感染的反应失调所导致的危及生命的器官功能障碍。 SAE患者:医生和护士有明确记录的认知和神经精神障碍,以及GCS<15分,ICU谵妄评估量表( Confusion Assessment Method of the Intensive Care Unit, CAM-ICU)确认的谵妄表现(如注意力不集中、定向障碍、思维改变、精神运动减慢、躁动等);基于振幅整合脑电图(αEEG)的多模态脑功能监测技术识别到的SAE特殊脑电改变:(1)θ波过度增多(低电压,频率普遍大于4Hz,小于8Hz);(2)δ波主导(中高电压,频率小于等于4Hz);(3)三相波(以典型或非典型的三相波为主要异常表现);(4)抑制型(双极导联或参考导联方式中活跃电极低于20 μV,表现为脑电静息)、或爆发-抑制型。

Inclusion criteria

Patients with sepsis: meet the diagnosis of sepsis 3.0 established by the "2016 International Conference on the Definition of Systemic Infection of the Society of Critical Care Medicine/European Society of Critical Care Medicine/American College of Chest Physicians/American Thoracic Society/Society of Surgical Infection" Criteria, which are defined as life-threatening organ dysfunction resulting from a dysregulated host response to infection. SAE patients: Doctors and nurses have clearly documented cognitive and neuropsychiatric disorders, as well as GCS<15 points, and delirium manifestations confirmed by the Confusion Assessment Method of the Intensive Care Unit (CAM-ICU) (such as attention Concentration, disorientation, thinking changes, psychomotor slowing, restlessness, etc.); SAE-specific EEG changes identified by amplitude-integrated electroencephalogram (αEEG)-based multimodal brain function monitoring technology: (1) Excessive increase of θ wave (low voltage, frequency generally greater than 4Hz, less than 8Hz); (2) delta wave dominant (medium to high voltage, frequency less than or equal to 4Hz); (3) three-phase wave (typical or atypical three-phase wave as the main (4) Inhibitory type (the active electrode is lower than 20 μV in the bipolar lead or reference lead mode, showing resting EEG), or burst-inhibitory type.

排除标准:

1)原发的神经系统疾病包括中枢神经系统感染(各种致病微生物引起的脑膜炎、脑炎)、脑血管病(脑出血、脑梗死等)、自身免疫性脑炎、癫痫等;2)非神经系统疾病包括代谢性疾病(例如,水电解质紊乱,低血糖,糖尿病酮症酸中毒,肝性脑病,肺性脑病,尿毒症性脑病等);3) 风湿血液系统病(如溶血-尿毒症综合征,系统性红斑狼疮等);4)中毒和戒断症状(如酒精,一氧化碳等);5)与镇痛镇静相关的认知和意识改变。

Exclusion criteria:

1) Primary nervous system diseases include central nervous system infection (meningitis and encephalitis caused by various pathogenic microorganisms), cerebrovascular disease (cerebral hemorrhage, cerebral infarction, etc.), autoimmune encephalitis, epilepsy, etc.; 2 ) Non-nervous system diseases include metabolic diseases (for example, water and electrolyte disorders, hypoglycemia, diabetic ketoacidosis, hepatic encephalopathy, pulmonary encephalopathy, uremic encephalopathy, etc.); 3) rheumatic hematological diseases (such as hemolytic- uremic syndrome, systemic lupus erythematosus, etc.); 4) intoxication and withdrawal symptoms (such as alcohol, carbon monoxide, etc.); 5) changes in cognition and consciousness associated with analgesia and sedation.
