Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 1 day and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Preterm newborn (>1 day postnatal age, gestational age >23 weeks, birth weight <1250g), intubated and mechanically ventilated, and breathing spontaneously, as defined by the ability to trigger the ventilator. The infant should be breathing on conventional ventilation (SIMV, assist control, or pressure support) with the following ventilator parameters: assist control/pressure support < 22 cm H2O, PEEP 4-6 cm H2O Fi02<.30

Who cannot join

  • Pneumothorax, degenerative neuromuscular disease, bleeding disorders, cardiovascular instability, cyanotic congenital cardiovascular disease, phrenic nerve damage/diaphragm paralysis, esophageal perforation, use of high frequency oscillatory or jet ventilation, contraindication to changing NG tube, or if infant is deemed "too unstable" by the clinical team. The use of narcotics is an exclusion criteria.

About this study

Official title: Use of Neurally Adjusted Ventilatory Assist (NAVA) in an Intubated Premature Infant: A Case Control Study on the Servoi Ventilator

The present protocol will demonstrate the feasibility and efficacy of a newly developed mode of mechanical ventilation, Neurally Adjusted Ventilatory Assist, commonly known as NAVA. During NAVA, the timing and magnitude of pressure delivered are controlled by the infants' diaphragm electrical activity (EAdi), a validated measurement of neural respiratory drive. Recent clinical trials in adults and term infants have shown that NAVA is more synchronous than conventional pressure support ventilation, and that NAVA delivers lower mean airway pressures to achieve the same ventilation and respiratory muscle unloading. NAVA has recently been approved for use in neonates by Health Canada and the FDA in the United States, and is commercially available on the Servoi ventilator (Maquet Critical Care, Solna, Sweden). The present protocol is designed as a "case study" where the researchers responsible would like to evaluate the feasibility and efficacy of ventilating a premature baby on NAVA with the Servoi for 12 hours.

What participants receive

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

  • NAVADevice

    Also called Servoi (Maquet Critical Care AB)

    Neurally Adjusted Ventilatory Assist (mechanical ventilation controlled by the diaphragm electrical activity)

What is being measured

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

  1. • Patient-ventilator synchrony (trigger delays, cycling-off delays) • Phasic electrical activity of the diaphragm EAdi • Tonic EAdi • tidal volume, airway pressure, respiratory rate • Oxygen saturation, transcutaneous CO2, FIO2

    Measured: end of the 12 hour trial

Secondary outcomes (1)
  1. • Number of times back-up rate started (per hour) • Number of PEEP or NAVA level adjustments

    Measured: end of the 12 hour trial

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing NAVA in people with Infant, Premature and Respiration, Artificial, run by Sunnybrook Health Sciences Centre at 1 site in Canada.

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 1 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: withdrawn, as of the sponsor's last update on 1 Jun 2016. 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 Canada. 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

• Patient-ventilator synchrony (trigger delays, cycling-off delays) • Phasic electrical activity of the diaphragm EAdi • Tonic EAdi • tidal volume, airway pressure, respiratory rate • Oxygen saturation, transcutaneous CO2, FIO2 (time frame: end of the 12 hour trial). 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 NCT00536445, 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 1 Jun 2016.
