Intermittent extracorporeal CO2 removal in chronic obstructive pulmonary disease patients: a fiction or an option.

PURPOSE OF REVIEW: Aim of this article is to review evidence recently generated on the application of extracorporeal carbon dioxide removal (ECCO2R) in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) requiring mechanical ventilation (invasive and non invasive) for hypercapnic respiratory failure.

RECENT FINDINGS: To date, the paucity of evidences on ECCO2R to decrease the rate of noninvasive ventilation (NIV) failure and to wean hypercapnic patients from invasive mechanical ventilation (IMV) precludes to systematically apply this technology to COPD patients.

SUMMARY: Although several efforts have been made to reduce invasiveness and to improve the efficiency of extracorporeal systems, further randomized studies are needed to assess the effects of this technique on both short-term and long-term clinical outcomes.
