Study of High Flow Nasal Cannula Oxygen for Bronchoscopy With Bronchoalveolar Lavage in ICU Patients

Completed

• Conditions: Respiratory Insufficiency

• Registration Number: NCT02523573
• Lead Sponsor: Hôpital Louis Mourier

Brief Summary

Bronchoscopy with bronchoalveolar lavage (BAL) is at risk for worsening hypoxemia in patients with acute respiratory failure (ARF). High-flow nasal cannula oxygen (HFNC) improves hypoxemia in ARF patients . We investigated its efficacy and tolerance in intensive care unit patients admitted for ARF requiring BAL.

Detailed Description

Prospective, observational, multicenter study in ARF patients (minimal pulse oximetry -SpO2- of 92% with an minimal oxygen flow of 6 L/min , respiratory rate \> 25/min (20/min if use of accessory respiratory muscles) with a compatible etiology. Primary outcome measure is increase in ventilatory support (non-invasive positive pressure ventilation (NPPV) or endotracheal intubation (ETI)) within the first 24h following BAL.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 30

Inclusion Criteria

• presence of acute respiratory failure: defined as respiratory rate greater than 25/min, (or greater than 20/min if use of accessory respiratory muscles was present), in patients requiring oxygen greater than or equal to 6 L/min to obtain a pulse oximetry greater than 92%
• need for bronchoalveolar lavage (decision to perform BAL was left at the physician's discretion)

Exclusion Criteria
