简要总结
Sepsis is life-threatening and dysregulated response to infection that results in endothelial activation and dysfunction that leads to systemic microvascular leak and multiple-organ failure. This study will identify patients that have sepsis with thrombocytopenia and randomize them to receive a unit of platelets or an equivalent volume of saline.
详细描述
Sepsis is life-threatening and dysregulated response to infection that results in endothelial activation and dysfunction that leads to systemic microvascular leak and multiple-organ failure. Emerging evidence indicates that platelets occupy a central role in maintaining the balance between vascular health and the response to environmental changes and vascular injury. Platelets are essential for vascular development and required for normal endothelial integrity. Platelets also function at the interface between thrombosis and inflammation. This study will identify patients that have sepsis with thrombocytopenia and randomize them to receive a unit of platelets or an equivalent volume of saline.
Our overall hypotheis is that normal platelet function is required to maintain vascular integrity and can be at least partially restored over the first 24 hours by platelet transfusion in septic patients with thrombocytopenia.

结局指标
主要结局
Biomarkers for vascular integrity
时间窗: 24 Hours
The ratio of Angiopoietin-2 to Angiopoietin-1 is used as a measurement of vascular integrity. We will determine the change in this ratio by measuring Angiopoietin-2 (pg/mL) and Angiopoietin-1 (pg/mL) at baseline (before infusion) and 24 hours after infusion and compare between the patients receiving a unit of platelets versus the patients receiving saline.
Biomarkers for inflammation
时间窗: 24 Hours
IL-6 and TNF-alpha are commonly measured as biomarkers for inflammation. We will measure the change in concentrations (pg/mL) of IL-6 and TNF-alpha between baseline and 24 hours and compare between the population receiving a unit of platelets versus the population receiving saline.
次要结局
- Incidence of Serious Adverse Events(30 days)
- Transfusion effects on cytokines(72 Hours)
- Transfusion effects on coagulation(72 Hours)
- Transfusion effects on platelet number(72 Hours)
