Acute severe asthma is a life-threatening medical emergency. Characteristics of asthma include increased airway resistance and dynamic pulmonary hyperinflation that can manifest in dangerous levels of hypercapnia and acidosis, with significant mortality and morbidity. Severe respiratory distress can lead to endotracheal intubation followed by mechanical ventilation, which can cause increased air trapping with dynamic hyperinflation, predisposing the lungs to barotraumas.
The present case report describes the use of the minimally invasive ECCOR ProLUNG (Estor) with protective low-tidal-volume ventilation, in a Caucasian patient with near-fatal asthma and with no response to conventional therapy.
Since hypercarbia rather than hypoxemia is the primary abnormality in status asthmaticus, a rescue therapeutic strategy combining the ECCOR membrane ProLUNG (Estor) with ultra-protective low-tidal-volume ventilation can be successfully applied to limit the risk of severe barotrauma during invasive mechanical ventilation. ECCOR ProLUNG is a partial respiratory support technique that, based on the use of an extracorporeal circuit with a gas-exchange membrane, achieves relevant CO clearance directly from the blood using double-lumen venous-venous vascular access, at blood flow in the range of 0.4-1.0 L/minute.
急性重症哮喘是一种危及生命的医疗急症。哮喘的特征包括气道阻力增加和动态肺过度充气,可表现为危险水平的高碳酸血症和酸中毒,具有显著的死亡率和发病率。严重的呼吸窘迫可导致气管插管并随后进行机械通气,这可导致动态肺过度充气引起的气体潴留增加,使肺部易发生气压伤。
本病例报告描述了在一名患有近乎致命哮喘且对传统治疗无反应的白种患者中,使用具有保护性低潮气量通气的微创ECCOR ProLUNG(Estor)。
由于高碳酸血症而非低氧血症是哮喘持续状态的主要异常,将ECCOR膜式ProLUNG(Estor)与超保护性低潮气量通气相结合的抢救治疗策略可成功应用于限制有创机械通气期间严重气压伤的风险。ECCOR ProLUNG是一种部分呼吸支持技术,基于使用带有气体交换膜的体外循环,通过双腔静脉 - 静脉血管通路直接从血液中实现相关的二氧化碳清除,血流速度在0.4 - 1.0升/分钟范围内。
