背景情况:
- COVID-19 可能导致血栓式微血管病 (TMA),这是一种涉及微血管血栓和内皮损伤的严重疾病.
- 包括血栓性血栓性缺血紫外线和非典型的血溶性尿素综合征在内的TMA显著增加了严重的COVID-19的发病率和死亡率.
- 了解COVID-19相关的TMA机制对于开发有效的治疗方法至关重要.
研究的目的:
- 审查治疗性血交换 (TPE) 在管理COVID-19相关的TMA方面的潜力.
- 检查TPE在清除导致COVID-19 TMA的炎症媒介和促血栓性因素中的作用.
- 探索TPE与补充抑制剂和免疫抑制剂等其他疗法结合的好处.
主要方法:
- 对COVID-19相关TMA的TPE病例报告和早期临床试验的文献审查.
- 分析TPE在缓解TMA病理生理方面的作用机制.
- 评估涉及TPE的联合治疗策略.
主要成果:

Venous Thrombosis III: Interprofessional Care
22
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
44
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
