概括
大血管封闭性中风转移前静脉内血栓溶解 (IVT) 改善了结果和再通道化,而不会增加出血风险. 建议在符合条件的患者中扩大IVT的使用.
科学领域:
- 神经学 神经学
- 心血管医学 心血管医学
- 紧急医疗 紧急医疗
背景情况:
- 患有大血管封闭 (LVO) 的急性缺血性中风往往需要医院间转移进行血栓切除术.
- 主要中风中心 (PSC) 开始治疗,但延迟可能会影响结果.
- 内静脉血栓溶解 (IVT) 是缺血性中风的关键早期治疗方法.
研究的目的:
- 评估大血管封闭 (LVO) 患者在医院间转移之前启动静脉血栓溶解 (IVT) 的疗效和安全性.
- 评估转移前IVT对功能结果,再通道化和内出血的影响.
- 确定影响转移患者使用IVT的因素.
主要方法:
- 对两组前期前部循环LVO患者的分析,这些患者从PSC转移到血栓切除术中.
- 在转移之前接受IVT的患者和没有接受IVT的患者之间的结局的比较.
- 使用倾向性得分重叠权重来平衡患者的共同变量.
- 在24小时内评估功能性结局 (mRS 0-2,mRS 0-1),动脉再通道化和内出血 (ICH,sICH).
主要成果:
- 在521名患者中,50%的患者在转移之前接受了IVT;保留的常见原因是时间窗口和抗凝药.
- IVT与良好的功能结果 (OR 2.17) 和优秀的功能结果 (OR 1.99) 的比率明显更高.
- 接受IVT的患者改善了设施间再通道 (OR 5.64),任何ICH和症状ICH的发病率相似.
结论:
- 在LVO患者的转移前IVT改善了再通道和功能结果,而不会影响安全.
- 目前在转移之前对IVT的利用率低于最佳 (50%),突出显示需要更广泛的应用.
- 探索扩展的IVT标准,包括超过4.5小时的治疗和抗凝血患者的治疗是有必要的.

Venous Thrombosis III: Interprofessional Care
28
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
48
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...

Anticoagulant Drugs: Low-Molecular-Weight Heparins
924
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...

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants
1.3K
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...

Venous Thrombosis IV: Nursing Management
27
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

Pulmonary Embolism III: Nursing Management
45
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...
