Study design:

Cohort study 

研究目的:

主要目的:探讨SAT患者入住ICU期间血小板输注与ICU死亡率的相关性。 次要目的: (1)评估血小板输注对SAT患者ICU住院时间、出血事件(如新出现的消化道出血、气道出血、鼻出血、口腔出血、皮下出血)及血栓事件(如深静脉血栓、肺栓塞)的影响; (2)评估血小板输注后第1天、第3天、第5天、第7天的血小板计数; (3)分析血小板形态参数(MPV、PDW)的动态变化与临床预后的关联; (4)探索不同血小板形态参数(MPV、PDW)动态变化与感染指标(如白介素-6(Interleukin-6, IL-6)、C反应蛋白(C-Reactive Protein, CRP)、降钙素原(Procalcitonin, PCT))的相关性。  

Objectives of Study:

Primary Objective: To investigate the correlation between platelet transfusion and ICU mortality in patients with Sepsis-Associated Thrombocytopenia (SAT) during their ICU stay. Secondary Objectives: (1) To evaluate the impact of platelet transfusion on ICU length of stay, bleeding events (e.g., newly occurring gastrointestinal bleeding, airway bleeding, epistaxis, oral bleeding, subcutaneous bleeding), and thrombotic events (e.g., deep vein thrombosis, pulmonary embolism) in SAT patients; (2) To assess platelet counts on Day 1, Day 3, Day 5, and Day 7 after platelet transfusion; (3) To analyze the association between dynamic changes in platelet morphological parameters (MPV, PDW) and clinical outcomes; (4) To explore the correlation between dynamic changes in different platelet morphological parameters (MPV, PDW) and infection markers (e.g., Interleukin-6 [IL-6], C-Reactive Protein [CRP], Procalcitonin [PCT]).
