Trial summary

The indications for mechanical ventilation (MV) include excessive work of breathing, with or without evidence of respiratory muscle fatigue. The setting of the MV is still a challenge because it is based on criteria understudied, often subjective and observer-dependent. Read more about this study

About this study

The indications for mechanical ventilation (MV) include excessive work of breathing, with or without evidence of respiratory muscle fatigue. The setting of the MV is still a challenge because it is based on criteria understudied, often subjective and observer-dependent. Despite several studies, to our knowledge has never been done before is the precise definition of the optimal range of ventilatory support. Novel and recognizable diagnostic techniques will be applied. No single parameter of the breathing pattern has good accuracy for the adjustment of ventilatory support. Non-invasive measures such as P0.1 and rate of muscle relaxation may have good accuracy for the adjustment of ventilatory support.

What participants receive

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

  • Variation of the level of pressure support during the mechanical ventilationProcedure or surgery

    The pressure support of the patient was changed form the baseline to 20 cmH20 and then stepwise decreased to 2 cmH20,

Study groupRoleWhat they receive
Pressure Support TitrationOtherThe analysis of the diagnostic accuracy of the breathing pattern variables, P 0.1 and the rate of tracheal muscle relaxation.
Receives: Procedure: Variation of the level of pressure support during the mechanical ventilation

What is being measured

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

  1. Measuring muscular force

    Muscular force measured by inspiratory force in centimeters of water (cmH2O)

    Measured: From the baseline ventilation to the minimum level of pressure support. Around 3 hours

Secondary outcomes (2)
  1. Measuring inspiratory drive

    Inspiratory drive measured in cmH2O in the first 100 milliseconds of the inspiration

    Measured: From the baseline ventilation to the minimum level of pressure support. Around 3 hours

  2. Measuring endurance

    Endurance measured by the maximal relaxation rate (cmH2O/10ms)

    Measured: From the baseline ventilation to the minimum level of pressure support. Around 3 hours

Questions about this trial

What is this clinical trial studying?

A study testing Variation of the level of pressure support during the mechanical ventilation in people with Acute Mechanical Ventilatory Failure, run by University of Sao Paulo General Hospital at 2 sites in Brazil.

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 4 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 19 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Brazil. 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?

Measuring muscular force (time frame: From the baseline ventilation to the minimum level of pressure support. Around 3 hours). 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 19 Jan 2017.
