概括
在住院的COVID-19患者中,治疗性氨酸抗凝剂减少了血栓栓塞事件和肺栓塞,但没有降低死亡率或ICU入院. 它确实增加了严重出血的风险.
科学领域:
- 临界护理医学 临界护理医学
- 药理学 药理学是指药理学的学科.
- 传染性疾病 传染性疾病
背景情况:
- 患有COVID-19的住院患者由于潜在的SARS-CoV-2诱导的原血栓状况而面临高血栓栓塞事件的风险.
- 抗凝血策略,特别是肝素,对于管理COVID-19相关的凝血病至关重要.
研究的目的:
- 进行随机临床试验的元分析,评估住院COVID-19患者用肝素治疗抗凝血剂的疗效和安全性.
- 为了比较治疗性肝素抗凝剂与预防性/中间剂量的关键临床结果.
主要方法:
- 在PubMed,Cochrane和Epistemonikos进行了系统的搜索,搜索到到2022年12月22日发表的研究.
- 包括九项随机临床试验,比较预防性/中间治疗与治疗性肝素抗凝药.
- 分析重点关注全因死亡率,血栓栓塞事件,肺栓塞,ICU入院/通风需求和严重出血.
主要成果:
- 治疗性氨酸抗凝药并没有显著降低全因死亡率或需要重症监护室入院或非侵入性通风的需要.
- 随着治疗剂量的使用,血栓栓塞事件 (RR 0.54) 和肺栓塞 (RR 0.37) 显著减少.
- 然而,治疗性抗凝剂与严重出血事件的显著增加有关 (RR 1.67).
结论:
- 虽然治疗性氨酸抗凝剂在住院COVID-19患者中有效减少血栓栓塞事件和肺栓塞,但它不会改善存活率或减少ICU入院.
- 这些发现突出了减少血栓事件的好处和增加重大出血风险之间的关键权衡.
- 最佳的抗凝策略需要仔细考虑个体患者的血栓形成和出血的风险因素.

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...

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants
1.2K
Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

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...
