Protective Ventilation With Carbon Dioxide (CO2) -Removal Technique in Patients With Adult Respiratory Distress Syndrome (ARDS)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00465309

Brief Summary:

30% of ARDS patients ventilated according to NIH protocol presents morphological (CT) and functional (Stress Index>1) conditions of hyperinflation even with Plateau pressure (Pplat) < 30 cmH2O; values of Pplat lower than 26 cmH2O were associated with more a condition of more protective ventilation.

In patients at risk of hyperinflation, use of alternative techniques such as CO2-removal my allow the reduction of Tidal Volume (Vt) and Pplat.

Condition or disease Intervention/treatment Phase
Adult Respiratory Distress Syndrome Procedure: protective ventilation with CO2 removal technique Phase 3

Detailed Description:
Aim of the study was to verify the efficacy of CO2-removal technique in reducing Vt and consequently Pplat to obtain a Stress Index value equal to 1.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 200 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Study Start Date : April 2007
Actual Study Completion Date : November 2008

Intervention Details:
  • Procedure: protective ventilation with CO2 removal technique
    In ARDS patients, presenting a Pplat ≥ 26 cmH2O, Vt was lowered (reaching a Pplat < 26) with CO2-removal veno-venous pump-driven bypass support for 48 consecutive hours with a pH > 7,30 or at least 72 hours from the beginning of the extracorporeal treatment.

Primary Outcome Measures :
  1. pulmonary inflammatory mediator reduction [ Time Frame: within the first 72 hours after enrollment ]
