英国多学会共识：左侧Impella支持患者的急救与复苏管理
本共识由英国多学会制定，针对使用左侧Impella微轴流泵支持的患者。Impella CP可经皮植入提供最高4.3 L/min流量，Impella 5.5需外科植入可提供最高5.5 L/min流量。共识旨在规范此类患者的急救和复苏管理流程。
要点
- Impella CP可经皮植入，提供最高4.3 L/min流量
- Impella 5.5需外科植入，提供最高5.5 L/min流量
- 右侧Impella RP可经皮植入，提供大于4 L/min流量
核心结论
- 英国多学会首次就左侧Impella支持患者的急救与复苏管理达成共识
研究设计与样本
- 英国多学会制定的专家共识声明
主要发现
- 心源性休克管理在过去数十年进展有限，血运重建仍是循证管理的主要手段
- 主动脉内球囊反搏泵(IABP)和静脉-动脉体外膜氧合(VA-ECMO)缺乏支持证据
关键数值与推荐
- Impella CP经皮植入，流量最高可达4.3 L/min
- Impella 5.5外科植入，流量最高可达5.5 L/min
- Impella RP右侧装置经皮植入，流量可超过4 L/min

Introduction The Impella is a microaxial flow pump that has seen increasing use and iterative development since its approval for use in 2008. 1 The two contemporary left-sided devices available are the Impella CP ( figure 1 ), which can be inserted percutaneously and provide flows up to 4.3 L/min and the Impella 5.5, inserted surgically and can provide flows of up to 5.5 L/min. 2 There is also a right-sided device, Impella RP, inserted percutaneously that can provide flows greater than 4 L/min. Figure 1 Impella CP components. There has been limited advance in the management of cardiogenic shock over the past decades. Revascularisation has been the mainstay of evidence-based management 3 4 with a lack of support for intra-aortic balloon pump (IABP) or venous-arterial extracorporeal membrane oxygenation (VA-ECMO). 5 6 Recently, the first positive randomised...
