Introduction:

The Crescent^® is a recently introduced dual lumen cannula by which veno-venous extracorporeal membrane oxygenation (VV ECMO) is delivered. It has a number of features that enhance its ease of placement, pressure-flow dynamics and may reduce catheter-related complication rates.

Methods:

We present the first case series of its kind analysing this device by means of a retrospective observational study of prospectively collected data from the first year of its use in a high volume severe acute respiratory failure centre (Glenfield, UK). We compare complication rates of the Crescent^®, with data from the international ELSO database and our own historic centre data and discuss subjective clinician experience of introducing this device.

Results:

Over the first 12 months of its use (23/09/2019–23/09/2020), 54 patients were cannulated using a Crescent^® catheter. There were no serious/life-threatening adverse events and a low number of minor cannula-related complications. Subjectively users found it has a number of advantages over other devices and configurations, not captured within current data collection frameworks.

Conclusion:

The Crescent^® is a safe and effective device by which to deliver VV ECMO support to patients with severe acute respiratory failure.

Crescent® 插管用于成人呼吸 VV ECMO 的经验：案例系列

介绍：

Crescent ^®是最近推出的双腔插管，通过它输送静脉-静脉体外膜肺氧合 (VV ECMO)。它具有许多功能，可增强其放置的便利性、压力流动动力学，并可降低导管相关并发症的发生率。

方法：

我们通过对在高容量严重急性呼吸衰竭中心（英国格伦菲尔德）使用第一年的前瞻性收集数据进行回顾性观察研究，展示了同类案例中的第一个分析该设备的系列。我们将 Crescent ^®的并发症发生率与来自国际 ELSO 数据库的数据和我们自己的历史中心数据进行了比较，并讨论了引入该设备的主观临床医生体验。

结果：

在其使用的前 12 个月（2019 年 9 月 23 日至 2020 年 9 月 23 日），54 名患者使用 Crescent ^®导管插管。没有严重/危及生命的不良事件和少数与插管相关的轻微并发症。主观上，用户发现它比其他设备和配置具有许多优势，这些优势在当前的数据收集框架中没有体现出来。

结论：

Crescent ^®是一种安全有效的设备，可用于为严重急性呼吸衰竭患者提供 VV ECMO 支持。
