About this study

Official title: Use of (Continous Positive Airway Pressure) CPAP in the Management of Acute Hypoxemic Respiratory Failure

Acute respiratory failure (ARF) is a frequent medical emergency, involving high costs for health organizations and patients who often require intensive care and respiratory assistance. According to an international study, 61% of hypoxemic patients in intensive care receive invasive ventilation [3]. Invasive mechanical ventilation is often unavailable in low-income countries and non-invasive ventilatory supports such as continuous positive airway pressure (CPAP) and high-flow oxygen therapy (HFO) were very useful during the COVID-19 pandemic. They reduced the rate of intubation and ICU admissions. In addition, CPAP can be used without a ventilator, no electricity is required. So, it could be a support of choice in low-income countries.

Used of Boussignac-type CPAP could potentially reduce the recourse to intubation in patients with acute hypoxemic respiratory failure in a context where access to invasive ventilation remains very limited.

Read the detailed description
  1. Hypothesis : The use of Boussignac-type CPAP could reduce the need for intubation in patients with acute respiratory failure in a setting where access to invasive ventilation remains very limited.
  2. Objectives 2.1 Primary Objective The primary objective is to evaluate the effect of CPAP use on the occurrence of intubation criteria at 7 days in patients presenting with ARF in the emergency department. 2.2 Secondary Objectives The secondary objectives are:
  • To assess the impact of CPAP use on 28-day mortality in patients with ARF
  • To assess the effectiveness of CPAP use on oxygenation in patients with ARF using the SpO2/FiO2 ratio
  • To assess the impact of CPAP use on hospital stay
  • To assess the safety of CPAP in patients with ARF 2.3 Ancillary Studies The ancillary studies are:
  • To assess the contribution of ultrasound in the management of ARF
  • To determine the etiologies and prognosis of ARF
  • To determine the etiologies and prognosis of patients with ARDS in intensive care
  • To assess the cost of ARF management
  1. Methodology 3.1 Study Setting

The Study will take place in the four adult university hospitals in Burkina Faso. Patient recruitment will take place during the same period in the emergency and intensive care departments. Patient inclusion in each hospital will be under the responsibility of an emergency department physician or an anesthesiologist-intensive care physician.

3.2 Study Type

This will be an open-label, multicenter, national randomized clinical trial. The type of oxygenation device does not allow for a blinded study.

3.3 Study Designs

Within 3 hours of validating the inclusion criteria, patients will be assigned to one of the two groups after signing the consent form.

  • In both groups, the oxygen flow will be adjusted to achieve an SpO2 of 92% or higher. SpO2 will be measured either using a monitor with integrated SpO2 measurement or using a portable device such as the Lifebox. The remainder of the patient's care will be administered according to the etiology of the ARF at the physician's discretion and according to recommandations. Any omission from the administration of study treatment will be noted on the collection sheet.
  • In the standard group Patients assigned to the standard treatment group will receive oxygen delivered via nasal prongs, simple face masks, or a high-concentration face mask (as needed) until intubation criteria are met, death occurs, or oxygen discontinuation criteria are met (an SpO2 greater than 92% without oxygen and a respiratory rate less than 25 breaths/min).

Patients who meet the intubation criteria will either be intubated if a bed and a ventilator are available in intensive care, or may receive, at the discretion of the physician, CPAP treatment as backup treatment in crossover, if invasive ventilation is not possible.

  • In the CPAP group Patients assigned to the CPAP plus oxygen group will receive periods of CPAP in addition to standard oxygen therapy. All study centers will use a Boussignac device connected to an oronasal mask consisting of a transparent mask and a soft inflatable cushion. The CPAP pressure level will be determined by the oxygen flow rate according to the correlation table. CPAP will start at 7.5 cmH2O (i.e., a Boussignac supply of 25 L/min). The pressure level will be decreased to 5 cmH2O (i.e., a Boussignac supply of 20 L/min) or increased to 10 cmH2O (i.e., a Boussignac supply of 30 L/min) depending on clinical response and tolerance. For at least the first 6 to 12 hours, CPAP will be administered continuously, then intermittently (for at least 6 hours/day) depending on patient tolerance. CPAP will be continued until endotracheal intubation criteria are met, death occurs, or treatment is discontinued according to the following criteria: SpO2 greater than 92% and respiratory rate less than 25 breaths/min with 3 L of oxygen or less between CPAP sessions. The criteria for discontinuing oxygen administration will be the same as in the standard group.

Patients who meet the intubation criteria will either be intubated if a bed and ventilator are available in intensive care, or will continue CPAP treatment if invasive ventilation is not possible.

3.4 Stratification

Randomization will be stratified by study center and baseline hypoxemia status. Stratification block randomization will be performed using a centralized, secure electronic system.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of patients with intubation criteria within 7 days

    The proportion of patients requiring endotracheal intubation within 7 days after randomization. Intubation will be defined as the insertion of an endotracheal tube for invasive invasive mechanical ventilation

    Measured: 7 days after randomization

Secondary outcomes (3)
  1. All cause mortality at 28 days

    Proportion of patients who have died from any cause within 28 days after randomization. Mortality will be assessed using medical records and/or direct patient follow-up

    Measured: 28 days after randomization

  2. Organ failure-free days at 7 days

    Organ failure will be defined using SOFA score or Modified SOFA score. The score ranges from 0 to 24.

    Measured: 7 days after randomization

  3. CPAP tolerance Assessment

    Patient discomfort will be assessed using a visual analog scale ranging from 0 (no discomfort) to 10 (maximum imaginable discomfort).

    Measured: 7 days after intiation CPAP
