まとめ
重度の出血,特に頭蓋内出血は,体外膜酸素化 (ECMO) によるCOVID-19患者の死亡率を大幅に増加させる. 長期にわたるECMOと血小板減少を予防することで,生存率を向上させることができます.
科学分野:
- クリティカル ケア 医療
- 血液学
- 感染症
背景:
- COVID-19 急性呼吸器障害症候群 (ARDS) の患者は,体外膜酸素療法 (ECMO) で治療を受けると,高い死亡リスクに直面します.
- 血液出血および血栓塞栓症 (BTE) は,ECMOで治療されたCOVID-19患者の重要な合併症である.
研究 の 目的:
- ECMOを受けるCOVID-19患者の位置と重症度を含むBTEの頻度と決定因子を特定する.
- 集中治療室 (ICU) の生存率とBTEのリスクに影響を与える要因を分析する.
主な方法:
- ドイツECMOのCOVID-19レジストールの遡及分析.
- ICU生存率とBTEリスクに関連する要因を特定するために,ロジスティック回帰が使用されました.
- データには945人の患者が含まれており,そのうち708人がBTEを発症しました.
主要な成果:
- 患者の75%がBTEを発症し,大きな出血事件が406例 (30%) と大きな血栓塞栓事件が258例 (19%) であった.
- 頭蓋内と肺の出血は最も一般的な主要な出血部位でした.
- 重度の出血,特に頭蓋内出血はICUでの死亡率の増加と強く関連しており (OR: 5. 3),重度の血栓塞栓症および軽度のBTEは生存率に有意な影響を及ぼさなかった.
結論:
- 重度の出血は,COVID-19 ECMO患者の死亡率を決定する重要な要因である.
- ECMOの長期間 (> 14 日) と持続性のある血小板減少症 (≥ 100,000/μL 72 時間) は,重度の出血の変更可能な危険因子である.
- 早期離乳戦略と血小板減少症の管理は,生存結果を改善するために不可欠です.

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...

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...

45
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...

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

01:24Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

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...
