About this study

the introduction of new MV modalities has shown promising results in reducing the incidence of weaning failure, mainly due to a more physiologic approach which allows respiratory muscle preservation. Among them, the Neurally Adjust Ventilatory Assist (NAVA) seemed to be associated with lower incidence of weaning failure and subsequent duration of mechanical ventilation, compared to standard modalities like the Pressure Support Ventilation (PSV) . Moreover, NAVA allows the evaluation of the diaphragm electrical activity (EAdi), an index of diaphragmatic neural respiratory drive. However, no study has compared TFic values during PSV and NAVA modalities in patients with difficult weaning from MV admitted in ICU.

Read the detailed description

Respiratory muscles dysfunction is one of the main causes leading to failure of weaning from mechanical ventilation (MV) in critically ill patients. Muscular activity is important during the inspiratory phase of ventilation, which is mainly due to diaphragm and external intercostal muscles. Diaphragm dysfunction is frequent among critically ill patients and ranges from 33 to 95% . Although several indexes have been investigated to help clinician in identifying its disturbance, their clinical value is controversial . External intercostal muscles dysfunction epidemiology is unknown because of lack of non-invasive tool to investigate such condition. However, the echography assessment of intercostal muscles thickening fraction (TFic) has shown promising results in this field as a non-invasive tool to assess inspiratory muscle function and predict weaning failure .

On the other hand, the introduction of new MV modalities has shown promising results in reducing the incidence of weaning failure, mainly due to a more physiologic approach which allows respiratory muscle preservation. Among them, the Neurally Adjust Ventilatory Assist (NAVA) seemed to be associated with lower incidence of weaning failure and subsequent duration of mechanical ventilation, compared to standard modalities like the Pressure Support Ventilation (PSV) [. Moreover, NAVA allows the evaluation of the diaphragm electrical activity (EAdi), an index of diaphragmatic neural respiratory drive . A recent study suggests that EAdi and derived parameters, may be helpful to predict weaning failure in chronic obstructive pulmonary disease (COPD) patients .

However, no study has compared TFic values during PSV and NAVA modalities in patients with difficult weaning from MV admitted in ICU.

the aim of this study will be the comparison of TFic values during PSV and NAVA modalities in patients with difficult weaning from MV admitted in ICU and the assessment of the inspiratory effort parameters and the occurrence of respiratory asynchrony in patients with difficult weaning from MV admitted in ICU.

Questions about this trial

What is this clinical trial studying?

An observational study of Respiratory Failure and Weaning Failure, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.

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 2 inclusion and 4 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 18 Oct 2024. 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 Italy. 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 giorgia GS spinazzola, md (0630154507, giorgia.spinazzola@policlinicogemelli.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

intercostal thickening fraction (time frame: From date of enrollment until the date of extubation (up to seven days)). 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 NCT05990348, which also lists 4 linked publications.

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 18 Oct 2024.
