An international phase III randomised trial comparing in severe Exacerbations of Chronic obstructive pulmonary disease the efficacy of Helium/Oxygen versus Air/Oxygen administered during spontaneous breathing and intermittent non-invasive ventilation. The E.C.H.O. ICU trial - ECHO ICU trial

Phase 1
Conditions
Patients eligible for this study are critically ill patients with COPD admitted in ICU for an exacerbation of their chronic disease with hypercapnic acute respiratory failure.

Exclusion Criteria

7)Patient previously randomised in the study,
8)Patient admitted in the ICU for more than 24 hours and/or having received
Non-Invasive Ventilation (NIV) in ICU for more than 6 hours (in total) for
the current exacerbation of COPD,
9)Patient with tracheostomy,
10)Patient who had lung transplant,
11)Patient having a contraindication to NIV:
11.a)Respiratory arrest, severe acute respiratory failure with high probability of
imminent intubation,
11.b) Sustained haemodynamic instability (hypotension with systolic blood
pressure < 90 mmHg despite volume loading and/or administration of
vasopressor treatment),

to selection.

Primary Outcome Measures
NameTimeMethod
Main Objective: To evaluate the efficacy of Helium/Oxygen 78%/22% compared to a conventional Air/O2 mixture in reducing endotracheal intubation rate and mortality in patients with severe hypercapnic exacerbations of Chronic Obstructive Pulmonary Disease (COPD) during their index Intensive/Intermediate Care Unit (ICU) stay;Secondary Objective: -To assess short term and long term efficacy criteria<br>-To assess the safety of the administration of He/O2 78%/22% in ICU<br>-To evaluate medico-economic data<br>;Primary end point(s): NIV failure (i.e., endotracheal intubation and/or death) during the index ICU stay for each randomised patient
