Clinical Trial Summary

Novel coronavirus (SARS-CoV-2: severe acute respiratory coronavirus 2) pneumonia often develop the acute respiratory distress syndrome (ARDS). Lung protective ventilation strategy consisting of low tidal volume and high positive end-expiratory pressure (PEEP) is recommended. However, it is not clear whether injured lungs from SARS-CoV-2 pneumonia have the same mechanical properties, especially response to PEEP as common ARDS. Therefore, the investigators propose an observational study to analyze respiratory mechanics and lung recruitablity using EIT (electrical impedance tomography) in patients with ARDS due to SARS-CoV-2 pneumonia.

Description:

The multi-center prospective observational study will enroll 20 adult ARDS patients under mechanical ventilation from Intensive Care Units (ICUs) in Japan and Peru. Informed consent will be waived due to the nature of observational study. Patients with positive SARS-CoV-2 infection will be included. Prior to initiating the protocol, patients will be sedated deeply with sedatives and/or opioids and paralyzed with a continuous infusion of rocuronium. The distribution of ventilation will be evaluated with EIT.
