Low-Flow CO2 Removal for Mild to Moderate ARDS With PRISMALUNG
Study Details
Study Description
Brief Summary
This pilot observational study will assess changes in pH /PaO2 /PaCO2, Respiratory Rate and device CO2 clearance in the first 24 hours of Extracorporeal CO2 removal (ECCO2R) following tidal volume (Vt), and plateau pressure reduction in patients with mild to moderate ARDS.

Detailed Description
Extracorporeal CO2 removal (ECCO2R) with a low-flow CO2 removal device (Prismalung, Gambro-Baxter) integrated on the Prismaflex platform (Gambro-Baxter) allows tidal volume (Vt) and plateau pressure reduction in patients with mild to moderate ARDS. This pilot observational study will assess changes in pH /PaO2 /PaCO2, Respiratory Rate and device CO2 clearance in the first 24 hours of ECCO2R following Vt and plateau pressure reduction in patients with mild to moderate ARDS. Safety variables during treatment will also be analyzed. A series of 20 consecutive patients will be included in this observational study.

Mild to Moderate ARDS on PRISMALUNG Extracorporeal CO2 removal (ECCO2R) with the PRISMALUNG device in patients with mild to moderate Acute Respiratory Distress Syndrome (ARDS). |
Device: CO2 removal with PRISMALUNG in ARDS
Observational study of patients with mild to moderate Acute Respiratory Distress Syndrome (ARDS) submitted to Extracorporeal CO2 removal (ECCO2R) with the PRISMALUNG device to allow ultraprotective mechanical ventilation with tidal volume reduction (from 6 to 4 ml/kg, predicted body weight) and plateau pressure reduction from 28-30 to 23-25 cmH2O.

- Change in vasopressor use [24 hours]
Epineprine and norepinephine dose, mcg/kg/min
- Evaluation of lung recruitment/derecruitment [24 hours]
With lung echography. Ccording to the method described by Bouhemad et al, Am J Respir Crit Care Med. 2011 Feb 1;183(3):341-7
- Lifetime of the extracorporeal circulation [7 days]
In hours
- Number of participants with adverse events directly related to ECCO2R [7 days]
Adverse events directly related to ECCO2R are hemolysis (serum free hemoglobin >500 mg/L), infection at the cannulation site, Hemorrhage at the cannulation site, air entry in the circuit.
