概括
针对急性缺血性中风的早期内血管血栓切除术 (EVT) 显著降低死亡率,并在90天内改善功能独立性. 晚期EVT (6-24小时) 在症状性内出血方面显示出类似的安全性,支持其在选定患者中的使用.
科学领域:
- 神经学 神经学
- 干预心脏病学 干预心脏病学
- 公共卫生 公共卫生
背景情况:
- 内血管血栓切除术 (EVT) 是急性缺血性中风 (AIS) 与大血管封闭 (LVO) 的关键治疗方法.
- 关于EVT的最佳时间窗口仍在争论中,这影响了临床决策.
研究的目的:
- 评估早期 (≤6小时) 和晚期 (>6-24小时) EVT 对AIS患者死亡率,功能结果和安全性的影响.
- 提供基于证据的关于EVT时间的建议.
主要方法:
- 2000-2024年间发表的随机对照试验和队列研究的系统综述和元分析.
- 搜索了四个主要的数据库:PubMed,科学网,科克伦图书馆和EMBASE.
- 分析了综合发病率,发病率差异 (IRD) 和症状性内出血 (sICH),死亡率和功能独立 (mRS) 的发病率比率 (IRR).
主要成果:
- 早期EVT (≤6h) 与晚期EVT (>6-24h) 相比,与明显较低的死亡率 (IRD -0.148,p=0.0012) 和更高的功能独立率 (IRD 0.32,p<0.0001) 相关.
- 在早期和晚期EVT组之间没有观察到症状性内出血 (sICH) 发生率的显著差异 (IRD -0.028,p=0.33).
- 在所有结果中都发现了中等到高的异质性.
结论:
- 治疗时间显著影响了接受EVT的AIS患者的临床结果.
- 早期EVT (≤6小时) 在死亡率和功能独立方面表现出优异的结果.
- 晚期EVT (>6-24小时) 对于精选的患者来说是一个安全的选择,没有增加sICH的风险,这强调了尽量减少治疗延迟的重要性.

Venous Thrombosis III: Interprofessional Care
278
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
311
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...

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,...
