Preoxygenation Using NIV in Hypoxemic Patients (PREOXY)

This study has been completed.

Critically ill patients are predisposed to oxyhaemoglobin desaturation during intubation. For the intubation of hypoxemic patients, preoxygenation using non invasive ventilation (NIV) is more effective at reducing arterial oxyhaemoglobin desaturation than standard method.

Objectives: To find out whether NIV, as a preoxygenation method, is more effective at reducing the degree of organ dysfunction/failure than standard preoxygenation during the week following endotracheal intubation.

Condition Intervention Phase
Critical Illness Hypoxemia Procedure: Non Invasive Ventilation Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Preoxygenation Using Noninvasive Ventilation Prior Intubation in Hypoxemic Patients

Further study details as provided by Assistance Publique - Hôpitaux de Paris:

Primary Outcome Measures:
  • The maximum Sequential organ failure assessment (SOFA) score observed during the first week following endotracheal intubation. [ Time Frame: the first week ]

Secondary Outcome Measures:
  • The mean drop in SpO2 during endotracheal intubation. [ Time Frame: during the intubation ]
  • Number of organ failures (SOFA score >2) [ Time Frame: during the 7 days after intubation ]
  • ICU length of stay [ Time Frame: during the stay in reanimation ]
  • Mortality [ Time Frame: in reanimation ]

Enrollment: 200

Non Invasive Ventilation
Procedure: Non Invasive Ventilation
Non Invasive Ventilation

Detailed Description:
During the inclusion period (at least 10 min and maximum 30 min), the patients ware a high FiO2 mask, driven by 10-15L/min oxygen and are randomly assigned to control or NIV group. Preoxygenation is then performed for a 3 minute period prior to a standardized rapid sequence intubation. For the control group, preoxygenation use a non-re-breather bag-valve mask driven by 15L/min oxygen. Patients allow to breath spontaneously with occasional assists (usual preoxygenation method). For the NIV group, pressure support mode is delivered by an ICU ventilator through a face mask adjusted to obtain an expired tidal volume of 7 to 10 mL/kg. The fraction of inspired oxygen (FiO2) was 100% and we used a PEEP level of 5 cmH2O.
