About this study

The purpose of this study is to document the prevalence and type of asynchronies incidence during invasive mechanical ventilation in pediatric patients breathing under pressure support.

And to observe the impact of adjusting the expiratory trigger setting on asynchronies, and compare these incidences with asynchronies measured in pediatric patient breathing under NAVA system (Neurally Adjusted Ventilatory Assist).

Read the detailed description

Two sessions will be recorded, one in PSV, one with NAVA, delivered in a random order after being sure the infant is calm and comfortable, according to his parents and/or the nurse in charge.

Criteria for initiating invasive ventilation and to start PSV will follow the usual practice guidelines of the unit.

Ventilation parameters in PS will be adjusted by the clinician in charge of the patient, as usual based on clinical observation. Investigators will not interfere with ventilator settings. Ventilation will be applied via an endotracheal tube, uncuffed for the majority (if infant < 5 years), according to commonly applied guidelines in this unit.

One 15 minutes session will be recorded, after being sure the infant is calm and comfortable according to the parents and/or the nurse in charge. Then the clinician in charge of the patient will modify the ETS, first decreasing it of 10% below the initial set value, and will be recorded the following 5 minutes after stabilization and secondly increasing it of 10% above the initial set value, and will be recorded the following 5 minutes after stabilization.

NAVA will be set to deliver initially the same peak pressure (comparable level of assist) than during the initial PS period. Same PEEP will be delivered in both modes. This is possible with a pre-visualization window, allowing adjustments before switching to the NAVA mode. Nava ventilation will be recorded during 20 minutes.

The 2 sessions, Pressure support and Nava, will be recorded consecutively.

Pressure supportActive comparatorin this arm, pressure support will be recorded under 3 conditions: * with the initial Expiratory Trigger Setting (ETS) * with ETS +10% * with ETS -10%
Receives: Other: Pressure Support
NAVAExperimentalNeurally Adjusted ventilatory Assist is a ventilation mode where the ventilator is piloted by the electrical activity of the diaphragm Ventilation is triggered and cycled off by the electrical activity of the diaphragm, the pressure delivered being proportional to this activity.
Receives: Device: NAVA

What is being measured

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

  1. asynchronies

    Asynchronies during mechanical ventilation are the following: Auto triggering, double triggering, late cycling, premature cycling and ineffective effort.

    all ventilatory parameters are recorded under Pressure support (3 phases: 3 levels of expiratory trigger setting, initial, +10% and -10%, 15 min, 5 min and 5 min respectively) and NAVA (1 phase, 20 min).

    Asynchronies will be determined by measuring each ventilatory cycle of all recordings.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Pressure Support and NAVA in people with Respiration, Artificial, run by University Hospital, Geneva at 1 site in Switzerland.

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 1 inclusion and 10 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 1 Sep 2010. 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 Switzerland. 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?

Results are not available in the source record.

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

Contact Laurence Vignaux (0041223727448, laurence.vignaux@hcuge.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

asynchronies (time frame: 12 months). 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 1 Sep 2010.
