Diffuse alveolar haemorrhage (DAH) is a catastrophic pulmonary complication of systemic lupus erythematosus. It can result in refractory hypoxaemia despite mechanical ventilation. Increasing lung compliance and worsening pulmonary hypertension can potentiate cardiogenic shock from acute right ventricular failure. In such patients with cardiopulmonary collapse, veno-arterial (V-A) ECMO maybe a viable option that can provide the required haemodynamic support. However, the use of V-A ECMO in such patients is limited due to an associated increased risk of bleeding. Our case report describes the successful use of V-A ECMO without the use of systemic anticoagulation in a patient with DAH. Despite the absence of systemic anticoagulation, no thrombotic complications within the circuit were noted.
Diffuse alveolar haemorrhage (DAH) complicating systemic lupus erythematous can present dramatically with sudden cardiopulmonary collapse.Extracorporeal membrane oxygenation (ECMO) can provide temporary haemodynamic support until conventional medical therapy can take effect.Despite the historical increased bleeding risk associated with ECMO, it can be safely used in patients with DAH to provide time for underlying organ recovery.
弥漫性肺泡出血(DAH)是系统性红斑狼疮的一种灾难性肺部并发症。尽管进行了机械通气,它仍可导致难治性低氧血症。肺顺应性增加和肺动脉高压恶化可加剧急性右心室衰竭引起的心源性休克。在这些发生心肺功能衰竭的患者中,静脉 - 动脉(V - A)体外膜肺氧合(ECMO)可能是一种可行的选择,能够提供所需的血流动力学支持。然而,由于出血风险增加,V - A ECMO在这类患者中的应用受到限制。我们的病例报告描述了一名DAH患者在未使用全身抗凝的情况下成功使用V - A ECMO。尽管未进行全身抗凝,但回路内未发现血栓形成并发症。
系统性红斑狼疮并发弥漫性肺泡出血(DAH)可突然出现心肺功能衰竭。体外膜肺氧合(ECMO)可提供临时血流动力学支持,直至传统医学治疗起效。尽管历史上ECMO存在出血风险增加的情况,但它可安全用于DAH患者,为潜在器官恢复争取时间。
