概括
与单独的抗凝血疗法 (ACT) 相比,全身再输疗法 (RT) 不能改善中期高风险肺栓塞 (PE) 患者的治疗结果. 这项研究没有发现死亡率或二次结果的显著差异,这表明RT应该保留给救援治疗.
科学领域:
- 心脏病学 心脏病学
- 肺部医学 肺部医学
- 关键护理医学 关键护理医学
背景情况:
- 肺栓塞 (PE) 影响全球数百万人,中等风险病例带来管理挑战.
- 目前对中期高风险PE的指导方针缺乏一致的治疗建议,导致不同的临床方法.
- 大约25%的PE病例属于中等风险类别,具有显著的死亡率 (5-25%).
研究的目的:
- 为了比较中期高风险PE患者的临床结果,仅用抗凝治疗 (ACT) 与全身再输疗法 (RT) 加上ACT治疗.
- 评估系统性再输血治疗在中期高风险PE患者中的有效性和安全性.
- 通过分析治疗结果,为中期高风险PE的管理策略提供信息.
主要方法:
- 在AdventHealth医院 (2019年1月 - 2020年12月) 对成年PE患者右心室应变的回顾性研究.
- 排除标准包括需要血管压缩剂,侵入性通风或通过机械血栓切除/导管导向血栓溶解进行初级治疗.
- 患者被分为标准ACT组和系统RT加ACT组进行结果比较.
主要成果:
- 在ACT和RT组之间在住院或30天死亡率方面没有发现显著差异 (p=0.450,p=0.591).
- 二次结果,包括大出血,血管压缩剂使用,机械呼吸,心肺复苏和输血,也没有显著差异.
- 值得注意的是,仅使用ACT组中的23.2%的患者需要二次血栓消化疗法,而RT患者更年轻,体质量指数更高.
结论:
- 对于中期高风险PE患者,不建议进行常规的全身再注血治疗;应保留为救援治疗.
- 该研究发现,与单独使用ACT相比,系统性RT对死亡率没有好处或对二次结果没有改善.
- 需要一致的管理方案和进一步的研究,以优化中等高风险PE的治疗方法.

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
329
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...

Pulmonary Embolism III: Nursing Management
364
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...

Pulmonary Embolism I: Introduction
521
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Venous Thrombosis III: Interprofessional Care
280
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...
