About this study

Official title: Evaluation of Airway Pressure Release Ventilation on Oxygenation in Acute Respiratory Distress Syndrome in Adult Patients With COVID-19 Pneumonia

The 2020 pandemic of the coronavirus (SARS-CoV2) has lead to an increase in ARDS cases requiring invasive mechanical ventilation in the ICU (Intensive Care Unit).

The investigators hypothesize that airway pressure release ventilation (APRV) could be beneficial in patients with ARDS secondary to SARS-COV2 viral pneumonia.

Read the detailed description

Lung protective mechanical ventilation is the cornerstone of ARDS management, reducing the work of respiratory muscles and optimizing gas exchange. However, it can be the source of deleterious effects, grouped under the terms of ventilator induced lung injury (VILI) and ventilator induced diaphragm dysfunction.

The protective ventilatory strategy has led to a significant improvement in the prognosis of ARDS patients, by reducing the volume of the air and oxygen mixture (lower tidal volume) delivered to the lungs and thus reducing the pulmonary stress and strain. However, this protective ventilation usually requires deep sedation and neuromuscular blockade to avoid deleterious patient-ventilator asynchrony.

Airway Pressure Release Ventilation (APRV) has been proposed to reduce patient-ventilator asynchrony and reduce the VILI. The operating principles of APRV are based on the presence of two pressure levels that are kept constant. Spontaneous breathing is possible at any time at both pressure levels if the patient is not deeply sedated or under neuromuscular blockade.

The investigators hypothesize that APRV mode could be beneficial on oxygenation and respiratory work in patients with ARDS secondary to SARS-COV2 viral pneumonia.

Study groupRoleWhat they receive
Airway Pressure Release VentilationPatients with COVID-19 ARDS requiring invasive mechanical ventilation in ICU, on Volume Assist Control ventilation (VAC) or Pressure Assist Control (PAC), are switched to airway pressure ventilation (APRV). If APRV doesn't lead to improvement in oxygenation the ventilatory mode is switched back to VAC or PAC ventilatory mode.

What is being measured

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

  1. Proportion of patients improving PaO2/FiO2 ratio at 6 hours of APRV

    Increase of at least 20% of the PaO2/FiO2 ratio

    Measured: 6 hours after starting APRV

Secondary outcomes (8)
  1. Number of interventions on ventilator settings

    Number of interventions by the physician on APRV settings

    Measured: 6 hours after starting APRV

  2. Change in mean blood pressure

    Variations of blood pressure in millimeters of mercury

    Measured: 6 hours after starting APRV

  3. Change in heart rate

    Variations of heart rate in beats per minute

    Measured: 6 hours after starting APRV

  4. Changes in catecholamine doses

    Variations of catecholamine doses in milligrams per hours

    Measured: 6 hours after starting APRV

  5. Changes in static compliance at the end of 6 hours of APRV

    Static compliance (Cstat) defined as : Cstat = (VT/(Pplat-PEPtot)) Tidal Volume (VT), Plateau pressure (Pplat) and Total Positive End-expiratory Pressure (PEEPtot)

    Measured: 6 hours after starting APRV

  6. Variations of minute ventilation

    Minute ventilation in liters per minute

    Measured: 6 hours after starting APRV

  7. Changes in static compliance 4 hours after stopping APRV

    Static compliance (Cstat) defined as : Cstat = (VT/(Pplat-PEPtot)) Tidal Volume (VT), Plateau pressure (Pplat) and Total Positive End-expiratory Pressure (PEEPtot)

    Measured: 4 hours after starting APRV

  8. Proportion of patients with a decrease of the PaO2/FiO2 ratio

    Percentage of patients with a decrease of the PaO2/FiO2 ratio

    Measured: 4 hours after stopping APRV

Questions about this trial

What is this clinical trial studying?

An observational study of ARDS and COVID19, run by Central Hospital, Nancy, France at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients improving PaO2/FiO2 ratio at 6 hours of APRV (time frame: 6 hours after starting APRV). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04386369, which also lists 2 linked publications.
