About this study

This study evaluates the respective values and combined CPIS (Clinical Pulmonary Infection Score), bronchoalveolar lavage (BAL), tracheal aspiration and pulmonary ultrasonography (LUS - Lung Ultrasound) for early diagnosis of ventilator- associated pneumonia (VAP).

Read the detailed description

Diagnosis and monitoring iconographic lung infection is essentially limited to chest radiography. But this one to bed is a source of information generally unreliable routine.

Lung ultrasound is now an additional technique for confirmation of diagnosis and followed by community acquired pneumonia and monitoring of ventilator-associated pneumonia. The specific pathophysiology of VAP makes particularly efficient lung ultrasound in the diagnosis and monitoring of these attacks. The patient mechanically ventilated, the colonization of the airways is responsible for a continuous seeding of the tracheobronchial tree. As the lesions are scattered throughout the lung parenchyma and are centered on a bronchiole; although there is a predominance of households in the areas most dependent lung. VAP is therefore characterized by inflammatory tissue expansion to the periphery, predominant at the lower lobes and partnering with a ventilation loss varies with the severity of the pneumonia.

Thus, it can be found at an early stage some cells infected around a bronchiole in contact with infected acini normally ventilated. At an advanced stage, this extension to the whole parenchyma results in the widespread presence of small outbreaks in pleural. They are easily and specifically detected by ultrasound in the form of vertical artifacts irregular spacing (irregular Lines B) or small pictures (<0.5 cm) rounded HYPOECHOIC (jucta pleural consolidation) for reliable diagnosis of VAP. The success of an antibiotic is detected by the disappearance of B lines and pleural jucta consolidations. The failure of antibiotic therapy by the appearance of new jucta pleural consolidations which may merge giving lobar consolidation. Community-acquired pneumonia is characterized by the spread of infection in a home adjacent pulmonary segments by providing a systematized typical lobar reached. The diagnosis and monitoring of community-acquired pneumonia is mainly based on monitoring the number and size of household lobar consolidation which is not sufficient for pneumonia Ventilator. This latest study shows that the intensity ultrasound signs is proportional to the extension of outbreaks (lobar consolidations homes and mini homes jucta pleural consolidation). Moreover unlike biological biomarkers such as procalcitonin, it does not reflect the intensity of inflammation.

What is being measured

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

  1. Sensitivity, specificity and diagnostic accuracy of lung ultrasound (in pleural consolidation homes and irregular lines B, basal consolidation) only and associated with the CPIS (clinical pulmonary infection score)

    Measured: 48h after mecanic ventilation

Secondary outcomes (2)
  1. Frequency of specific sonographic signs (irregular B lines, pleural consolidation in household) during the VAP

    Measured: 48h after mecanic ventilation

  2. Diagnostic approach integrating CPIS (Clinical Pulmonary Infection Score), tracheal aspiration and lung ultrasound (LUS - Lung Ultrasound) for the early diagnosis of VAP

    Measured: 48h after mecanic ventilation

Questions about this trial

What is this clinical trial studying?

An observational study of Ventilator-associated Pneumonia and Sepsis, run by Fondation Hôpital Saint-Joseph.

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 7 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: finished, as of the sponsor's last update on 1 Sep 2015. 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?

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?

Sensitivity, specificity and diagnostic accuracy of lung ultrasound (in pleural consolidation homes and irregular lines B, basal consolidation) only and associated with the CPIS (clinical pulmonary infection score) (time frame: 48h after mecanic ventilation). 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 2015.
