Active clinical trials for "Respiratory Insufficiency"

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.

This study will determine whether selective serotonin reuptake inhibitors (SSRI) exacerbate opioid induced respiratory depression in patients initiating treatment for underlying conditions such as depression or an anxiety disorder. Next to paroxetine which has been evaluated in a previous study in healthy volunteers sertraline, citalopram and escitalopram will be evaluated with regards to its influence on opioid induced respiratory depression.

The objective of ILAN is to assess the safety, feasibility and bronchodilator efficacy of in-line bronchodilator nebulizer delivery with VMN via HFNC system in hypoxemic respiratory failure patients treated with bronchodilators and compare this method to standard-nebulization using a jet nebulizer with a facial mask. The investigators hypothesized that aerosol nebulization using HFNC/VMN represents safer and more convenient approach in hypoxemic respiratory failure patients in comparison to conventional therapy while providing similar bronchodilator efficacy.

Amyotrophic lateral sclerosis (ALS) is a rare and serious neurodegenerative disease causing degeneration of motor neurons. . It leads to a progressive paralysis of the muscles involved in voluntary motricity. In France, its incidence is 2.5/100,000 inhabitants per year. The death of patients is mainly caused by a progressive attack of the respiratory muscles. Indeed, the thorax is no longer actively mobilized to the maximum amplitude, it will lose its flexibility. A restrictive syndrome sets in followed by alveolar hypoventilation. Bronchial congestion may be concomitant. Management is then based on non-invasive ventilation (NIV). This step, which is difficult for patients to accept psychologically, must be delayed as much as possible. However, to date, there are no precise recommendations on preventing the appearance of this restrictive syndrome and on slowing down the deterioration of lung function in patients. The pressure relaxer (RLX) is an instrumental aid allowing on the one hand to mobilize the thorax thanks to hyper insufflations, and on the other hand to increase the effectiveness of the cough. The use of this device in physiotherapy is part of the HAS recommendations to promote decluttering. However, we believe that RLX in patients with ALS, through the pulmonary alveolar recruitment it induces, could be relevant at an earlier phase, for the prevention of the decline in pulmonary functions: the restrictive syndrome, bronchial congestion and alveolar hypoventilation. So ultimately, the quality of life and survival of these patients would be improved. It is in this context that this multicenter randomized controlled study RELAX'SLA takes place in order to evaluate the effects of the early use of the pressure relaxer on the respiratory impairment of patients with ALS.

High velocity nasal insufflation (HVNI), a form of HFNC that utilizes a small bore nasal cannula to generate higher velocities of gas delivery than HFNC which uses large bore cannula, has the ability to accomplish complete purge of extra thoracic dead space at flow rates of 35 litres/min and may be able to provide ventilatory support in patients with respiratory failure in addition to oxygenation support in patients with overlap syndrome. This study aims to evaluate the effectiveness of HVNI compared to NIMV in management of respiratory failure in patients with obesity hypoventilation syndrome and overlap syndrome.

This study assesses the feasibility of digital data collection for a randomized controlled trial in a quaternary pediatric intensive care unit and the effect of two commonly used mechanical ventilation modes on gas exchange (CO2) in children over 2 days after randomization. This is a single-center, open-labelled, randomized controlled trial with two parallel 1:1 treatment arms: pressure controlled (PC) vs pressure-regulated volume controlled (PRVC) mechanical ventilation modes. Use to routine digital data is essential to enable health learning systems and to provide rapid clinical trials readiness, as the pandemic has demonstrated. Despite availability of data to perform digital trials in PICU settings, these are yet scarcely done.

Pediatric patients often require prolonged mechanical ventilation after cardiac surgery which comes with many undesirable effects. As a result, neurally-adjusted ventilatory assist (NAVA) and biphasic positive airway pressure support (BiPAP) have been developed as non-invasive alternatives to providing respiratory support post-operatively. The investigators hypothesize that providing synchronized biphasic support with NAVA will be associated with shorter duration of non-invasive respiratory support, less sedation requirements, and reduced length of hospital stay. This is a prospective, randomized study. Subjects are randomized to receive either NAVA or BiPAP following their cardiothoracic surgery.

Randomized clinical trial in which the main objective is to compare High Flow Nasal Cannula (HFNC) versus the standard respiratory care in the alleviation of dyspnea perception in patients with do-not-intubate (DNI) order. This is a pragmatic study that will take place in 10 Brazilians ICU facilities which are already participating in the main study RENOVATE NCT03643939.

Trial design: Prospective, multi-centre, randomised, pragmatic, double blind trial Methods: Participants: Adult (>18 years) within 24 hours of admission to intensive care unit with proven or suspected COVID-19 infection, whether or not mechanically ventilated. Exclusion criteria: symptoms of febrile disease for ≥1 week, treatment limitations in place or moribund patients, allergy or intolerance of any study treatment, incl. long QT syndromes, participation in another outcome-based interventional trial within last 30 days, patients taking Hydrochloroquine for other indication than COVID-19, pregnancy. Interventions: Patients will be randomised in 1:1:1 ratio to receive Hydrochloroquine 800mg orally in two doses followed by 400mg daily in two doses and Azithromycin 500 mg orally in one dose followed by 250 mg in one dose for a total of 5 days (HC-A group) or Hydrochloroquine+ placebo (HC group) or placebo + placebo (C-group) in addition to best standard of care, which may evolve during the trial period but will not differ between groups. Objective: To test the hypothesis that early administration of combination therapy slows disease progression and improves mechanical-ventilation free survival. Outcomes: Primary outcome: Composite percentage of patients alive and not on end-of-life pathway who are free of mechanical ventilation at day 14. Secondary outcomes: Composite percentage of patients alive and not on end-of-life pathway who are free of mechanical ventilation at day 14 in the subgroup of patients without the need of mechanical ventilation at baseline.
