Study Summary

This trial found that consolidations caused by infection have different effects on the lungs than those caused by other factors.

Who is the study for?

This trial is for mechanically ventilated patients with lung issues like pneumonia or a collapsed lung, visible on chest X-rays or CT scans. It's not for those in other studies, with poor ultrasound imaging conditions (like obesity), recent antibiotic changes, right heart failure, mobility restrictions of upper body, bronchoscopy contraindications, or known high blood pressure in the lungs.Check my eligibility

What is being tested?

The study tests how well lung ultrasound and pulsed-wave Doppler can identify different types of lung consolidations by comparing regional acceleration time (RAcT) values between infectious and atelectatic consolidations. Measurements are taken initially and again between days 3 to 5.See study design

What are the potential side effects?

Since this trial involves non-invasive imaging techniques rather than medications, side effects are minimal but may include discomfort from positioning during the ultrasound and potential risks associated with mobilizing critically ill patients.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.

Primary outcome measures

Presence of visible blood vessels on colour Doppler in lung consolidations

Trial Design

2Treatment groups

Experimental Treatment

Group I: Lung ultrasound and Doppler, pneumoniaExperimental Treatment1 Intervention

In this group, a lung ultrasound examination using pulsed-wave Doppler will be performed in patients with high clinical suspicion of pneumonia on Day 0. A bronchoalveolar lavage will also be performed on Day 0.

Group II: Lung ultrasound and Doppler, atelectasisExperimental Treatment1 Intervention

Patients without clinically active pulmonary disease but presenting a consolidation of suspected atelectatic nature. Fever, hypothermia, leucocytosis and leucopenia will not be present. Tracheal secretions will remain unchanged. There will be no deterioration of oxygenation. In this group, a lung ultrasound examination using pulsed-wave Doppler will be performed on Day 0.
