About

Background: Acute exacerbation of chronic obstructive pulmonary disease (ae-COPD) has a gold standard treatment: non-invasive ventilation (NIV). However, this treatment sometime fails, and an invasive mechanical ventilation (IMV) is required. The extracorporeal CO₂ removal (ECCO₂R) device can be an alternative to intubation. The aim of the study is to evaluate ECCO₂R efficiency and safety and enlighten ECCO₂R benefit/risk compared to IMV.

Methods: Successive ae-COPD patients for whom NIV failed were retrospectively analyzed during two periods: before and after the ECCO₂R device implementation in our ICU in 2015. We considered the before period as standard of care and patients were treated with IMV. The ECCO₂R device was a pump-driven veno-venous system (Xenios AG).

Full description

The study compare 2 strategies for COPD patients not responding to non invasive ventilation: the gold standard which is mechanical ventilation and a new technique which is extracorporeal CO2 removal. This technique have been implemented in februrary 2015 in our intensive care unit so we choose to compare patients' outcome before and after the arriving of this device.
