Role of Lung Ultrasound Imaging and Pulsed-wave Doppler in the Assessment of Lung Consolidations in Mechanically Ventilated Patients.
Status: Recruiting
Location: See location...
Intervention Type: Other
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
In infectious lung consolidations, the inhibition of hypoxic pulmonary vasoconstriction (HPV) results in a higher regional acceleration time (RAcT) compared to the RAcT measured in atelectatic consolidations.
Eligibility

Estimated Completion Date: 2024-11-01
Participants
Target number of participants: 64
Treatments
Other: Lung ultrasound and Doppler, pneumonia
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.
Other: Lung ultrasound and Doppler, atelectasis
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.
