Clinical Trial Summary

In patients suffering from acute respiratory failure, ineffective cough and the consequent retention of secretions are common clinical problems, which often lead to the need for tracheostomy for the sole purpose of aspiration of secretions from the airways. Mechanically ventilated critically ill patients often have impaired mucus transport which is associated with secretion retention and subsequent development of pneumonia. The accumulation of tracheobronchial secretions in ventilated patients in ICU is due not only to an increased production, but also to a decreased clearance. In the event that secretions occlude a bronchus, an atelectasis of the lung parenchyma is created downstream. Therefore, it is often necessary to perform a flexible bronchoscopy (FOB) to proceed with the removal of the secretion plug. After its removal, the lung is supposed to be reventilated and recruited. In intubated ICU patients, the application of a recruiting maneuver (RM) is commonly used to reopen the collapsed lung in patients with Acute Respiratory Distress Syndrome or in case of atelectasis in other clinical conditions. However, no studies have so far investigated the role of the application of a RM after a FOB performed to remove a secretion plug in intubated ICU patients. This observational and physiological study aims to assess if the application of a RM would modify the lung aeration soon after an FOB to remove secretion plug (first outcome). Moreover, the study aims to assess if EIT could be an additional bedside imaging tool to monitor modifications of lung ventilation and aeration during and after a flexible bronchoscopy, as compared with both chest-X-ray and lung ultrasound.
