• Study Type: interventional
• Target: 30
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of the study RVSTAR is to evaluate whether echocardiographic criteria exploring the right ventricle can predict the inefficacy and/or the unsafeness of recruitment maneuvers in patients suffering from acute respiratory distress syndrome

Conditions

Acute Respiratory Distress Syndrome

Keywords

Acute respiratory distress syndrome; Echocardiography; Recruitment maneuver

Outcome Measures

Primary Outcomes (1)

• Efficacy and safety of recruitment maneuvers in patients with Acute Respiratory Distress Syndrome.

  A recruitment maneuver is considered effective if the partial pressure of oxygen in arterial blood PaO2 measured one hour after the completion of recruitment maneuver is 20 % higher than PaO2 before recruitment maneuver. A recruitment maneuver is considered unsafe if systolic arterial pressure decreases 40 % under its value before recruitment maneuver and/or if systolic arterial pressure decreases under 70 mmHg and/or if arrhythmias (third degree atrio-ventricular block, ventricular tachycardia, ventricular fibrillation, atrial fibrillation)occur during the achievement of recruitment maneuver in patients suffering from Acute Respiratory Distress Syndrome. Can echocardiography predict the inefficacy and/or unsafeness of recruitment maneuvers in patients suffering from Acute Respiratory Distress Syndrom ?

  Up to 2 years

Secondary Outcomes (3)

• Feasibility of the measurement of Longitudinal Strain and Strain Rate of the right ventricle in patients suffering from Acute Respiratory Distress Syndrome.

  Up to 2 years

• Comparison of the results of echocardiographic measurements between the group CONTROL and the group FAILURE.

  Up to 2 years

• Evaluate the effect of the inefficacy and/or of the unsafeness of the recruitment maneuver on the future of the patient suffering from Acute Respiratory Distress Syndrome.

  Up to 2 years

Study Arms (1)

Device: Echocardiography

Interventions

Echocardiography DEVICE

In the study RVSTAR, all the patients included will undergo an echocardiography in order to find an echocardiographic criterion predictive of the inefficacy and/or unsafeness of recruitment maneuver.
