Brief Summary:

The study´s intention is to evaluate the feasibility, safety and effectiveness of a pump driven extracorporeal device for removal of carbon dioxide from the blood in oder to avoid intubation and invasive mechanical ventilation in patients with acute respiratory failure retaining carbon dioxide due to the failure of their ventilatory muscle pump and not responding to prior non-invasive mask ventilation.

Detailed Description:

The study´s intention is to evaluate the feasibility, safety and effectiveness of a pump driven extracorporeal device for removal of carbon dioxide from the blood in oder to avoid intubation and invasive mechanical ventilation in patients with acute respiratory failure retaining carbon dioxide due to the failure of their ventilatory muscle pump and not responding to prior non-invasive mask ventilation. Since intubation with subsequent (prolonged) invasive mechanical ventilation is associated with considerable side effects this new strategy has the potential to improve overall clinical outcome in this selected patient group.

Intervention/treatment

Experimental: ECLA-group; Treatment with a pump driven, venovenous extracorporeal lung assist

Device: vv-ECCO2R (Novalung GmbH, Germany); Treatment with the extracorporeal lung assist (ECLA) The ECLA is a pump driven (centrifugal pump) venovenous circuit, which removes carbon dioxide from the patients blood by means of a membrane through which the patients blood runs on the one side of the membrane and sweep gas on the other side removing the patient´s carbon dioxide. Blood flow range from 0.5 to 4.5 l/min and sweep gas flow between 1 and 10 l/min. At blood flows of 2 l/min and higher the device also oxygenates the patients blood. The diameter and length of cannulas and the sites of venous insertions are left to the decision of the treating physician. Cannulas are inserted in seldinger technique under sterile conditions. Function and patency of the extracorporeal circuit requires mild therapeutic anticoagulation.
