About this study

Official title: Evaluation of a New System to Clear CO2 During Noninvasive Ventilation (NIV)

In this randomized cross over study the investigators will evaluate the effects on gas exchange and patients' tolerance of a new CO2 non rebreathing devices incorporated in the mask vs the traditional mask COPD patients undergoing NIV for an episode of Acute Hypercapnia Respiratory Failure, will be randomized after at least 12 hour of ventilation to 1 h.trial with the usual full face mask or the same mask with the addition of a new CO2 clearance device

Read the detailed description

In this randomized cross over study the investigators will evaluate the effects on gas exchange and patients' tolerance of a new CO2 non rebreathing devices incorporated in the mask vs the traditional mask COPD patients undergoing NIV for an episode of Acute Hypercapnia Respiratory Failure, will be randomized after at least 12 hour of ventilation to 1 h.trial with the usual full face mask (FM) or the same mask with the addition of a new CO2 clearance device (FM+d) In the interval between NIV sessions, arterial blood gases will be monitored and if PaCO2 will return to a baseline value with a tolerance of 10%, the patients will undergo another 1 h trial using the other mask.

The subjects will be studied in the sitting position and asked to relax throughout the period of the study.

The patients will be ventilated using pressure support ventilation (PSV) The order of use of the two interfaces will be determined for each patient by a previously generated randomized sequence.

FIO2 will be adjusted to obtain oxygen saturation around 92% at baseline and never modified throughout the study.

End-expiratory pressure will always fixed at 2 cm H2O, and trigger sensitivity will set at -0.5 cm H2O.

Inspiratory assistance during either PSV will be titrated to achieve a tidal volume between 6-8 mL/kg while avoiding occurrence of discomfort or visually assessed "wasted efforts".

The ventilatory settings will determined at the beginning of the first trial, and maintained unmodified throughout all the 3 runs.

Patient tolerance to NIMV, defined as the level of comfort using the different mask, will be assessed by means of a scale used and validated in previous studies that is defined as follows: 1, bad; 2, poor; 3, sufficient; 4, good; 5, very good. The patients were asked by the respiratory therapist to answer the following question: "How do the patient feel your breathing is using this mask?" The patient will give the score to the therapist at the end of each run, just before ABG measurements.

What participants receive

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

  • DiMax Zero Total face mask "R",Device

    a non-CO2 rebreathing device included directly in the full face mask

  • traditional face maskDevice

    a traditional mask without a non-CO2 rebreathing device included directly in the full face mask

What is being measured

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

  1. changes in arterial blood gases (ABGs)

    Recording of carbon dioxide arterial tensione and oxygen arterial tension using an arterial puncture performed in the radial artery

    Measured: immediate

  2. patient's tolerance to the mask

    the tolerance will be recorded using an ad hoc scale

    Measured: immediate

Questions about this trial

What is this clinical trial studying?

A study testing DiMax Zero Total face mask "R", and traditional face mask in people with Acute Hypercapnic Respiratory Failure, run by IRCCS Azienda Ospedaliero-Universitaria di Bologna.

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 3 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: status not confirmed, as of the sponsor's last update on 28 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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

Contact stefano nava (3333751828, stefanava@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

changes in arterial blood gases (ABGs) (time frame: immediate). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 28 Nov 2018.
