About this study

Official title: High-flow Nasal Therapy for Early Management of Hypercapnic Respiratory Failure Due to Acute Cardiogenic Pulmonary Edema in the ED: a Prospective Observational Study

High flow nasal therapy (HFNT) has not been well evaluated for treating hypercapnia The purpose of this study is to determine whether high flow nasal therapy (HFNT) can decrease hypercapnia and improve respiratory distress parameters in Emergency Department patients with acute hypercapnic respiratory failure related to cardiogenic pulmonary edema and to compare its efficacy to that of non invasive ventilation.

Read the detailed description

This is a prospective observational study conducted as a preliminary study to the randomized controlled OPTICAP trial (NCT02874339).

Prospective observational exploratory study including ED patients with a suspected diagnosis of acute hypercapnic respiratory failure related to cardiogenic pulmonary edema who require NIV according to the joint recommendations from the French society of anaesthesia and intensive care and the French society for intensive care.

Patients will receive a 1hr treatment session by either NIV or HFNT, depending on the attending ED physician expertise in using HFNT Repeat evaluation of arterial blood gases and respiratory parameters and dyspnea will be performed before and after treatment sessions according to current guidelines.

Improvement in PaCO2 and other respiratory parameters after 1hr treatment by HFNT will be analysed and compared to that of NIV.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • High flow nasal therapy (HFNT) : Optiflow™Device

    Also called High flow nasal cannula, High flow nasal oxygen, Optiflow™

    HFNT will be administered through a heated humidifier (Airvo 2, Fisher and Paykel healthcare) and applied through large bore binasal prongs.

    Initial gas flow rate will be set at of 60 l/min and adjusted to 40-50 l/min based on patient's tolerance. FiO2 will be adjusted to maintain an SpO2 ≥ 92%. Initial temperature will be set at 37° and reduced according to patient's tolerance

  • Non invasive ventilation (niv)Device

    NIV will be delivered through a face mask connected to a dedicated ventilator with pressure support applied in a noninvasive ventilation mode (Monnal T75, Airliquide Medical Systems, Antony, France).

    The Pressure-support level will be adjusted to obtain an expired tidal volume of 6-8 ml/kg of predicted body weight and a respiratory rate of 25-30 b/min. PEEP (range 5-10 cm of water) and FiO2 will be adjusted to maintain an SpO2 ≥92% and to patient's comfort.

What is being measured

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

  1. Change in PaCO2 after a 1-hour treatment session

    PaCO2 will be measured from standard laboratory arterial blood gas analysis performed at the end of the first 1-hour-treatment session

    Measured: 1 hour

Secondary outcomes (6)
  1. blood gas (PaO2, pH, SaO2)

    blood gas (PaO2, pH, SaO2) measured from standard laboratory arterial blood gas analysis at the end of each 1h-ventilatory support session and throughout ventilatory support

    Measured: at 1 hour

  2. Respiratory rate

    Respiratory rate, measured over 1-min as part of standard clinical assessment after each 1h ventilatory support session and throughout ventilatory support

    Measured: at 1 hour

  3. signs of increased work of breathing

    signs of increased work of breathing assessed based on patient's use of accessory respiratory muscles and paradoxical abdominal movement and measured using 5-point likert scales ranging from 1 to 5. Signs of increased work of berthing will be assessed at the end of each 1h ventilatory support sessions throughout ventilatory support

    Measured: at 1 hour

  4. Dyspnea

    Dyspnea recorded by the patient using a Modified Borg scale ranging from 0 to 10.

    Dyspnea will be measured at the end of each 1h ventilatory support sessions and throughout ventilatory support

    Measured: at 1 hour

  5. comfort

    Comfort recorded by the patient using a visual analog scale from 0 to 10. Comfort will be assessed at the end of each 1h ventilatory support sessions and throughout ventilatory support

    Measured: at 1 hour

  6. Proportion of patients

    Proportion of patients with a normalized PaCO2 (PaCO2 equal or lower than 45 mmHg),

    Measured: at 1 hour

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Cardiogenic Pulmonary Edema and Hypercapnic Respiratory Failure, run by University Hospital, Montpellier 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 11 inclusion and 3 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?

The record says: finished, as of the sponsor's last update on 25 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change in PaCO2 after a 1-hour treatment session (time frame: 1 hour). 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 NCT03883555, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2019.
