Active clinical trials for "Respiratory Distress Syndrome"

This study evaluates a pharmacological intervention to relieve dyspnea in intensive care unit patients. Indeed, opioids can be particularly beneficial since 1) dyspnea and pain share many similarities, 2) the benefit of opioids on dyspnea has been clearly demonstrated in other populations. However, to date, data regarding the impact of morphine on dyspnea in intensive care unit patients admitted for acute respiratory failure are scarce. There may be a reluctance of physicians to prescribe opioids that is not scientifically justified. The study will focus on patient reported outcome (PRO) criteria. The ultimate goal of this pilot study is to design the protocol of a future pragmatic trial.

The purpose of this study is to evaluate the efficacy and safety of ruxolitinib in the treatment of patients with COVID-19 severe pneumonia.

Acute respiratory distress syndrome (ARDS) is defined using the clinical criteria of bilateral pulmonary opacities on a chest radiograph, arterial hypoxemia (partial pressure of arterial oxygen [PaO2] to fraction of inspired oxygen [FiO2] ratio ≤ 300 mmHg with positive end-expiratory pressure [PEEP] ≥ 5 cmH2O) within one week of a clinical insult or new or worsening respiratory symptoms, and the exclusion of cardiac failure as the primary cause. ARDS is a fatal condition for intensive care unit (ICU) patients with a mortality between 30 and 40%, and a frequently under-recognized challenge for clinicians. Patients with severe symptoms may retain sequelae that have recently been reported in the literature. These sequelae may include chronic respiratory failure, disabling neuro-muscular disorders, and post-traumatic stress disorder identical to that observed in soldiers returning from war. The management of a patient with ARDS requires first of all an optimization of oxygenation, which relies primarily on mechanical ventilation, whether invasive or non-invasive (for less severe patients). Since the ARDS network study published in 2000 in the New England Journal of Medicine, it has been internationally accepted that tidal volumes must be reduced in order to limit the risk of alveolar over-distension and ventilator-induced lung injury (VILI). A tidal volume of approximately 6 mL.kg-1 ideal body weight (IBW) should be applied. Routine neuromuscular blockade of the most severe patients (PaO2/FiO2 < 120 mmHg) is usually the rule, although it is increasingly being questioned. Comprehensive ventilatory management is based on the concepts of baby lung and open lung, introduced respectively by Gattinoni and Lachmann. According to these concepts, it must be considered that the lung volume available for mechanical ventilation is very small compared to the healthy lung for a given patient (baby lung) and that the reduction in tidal volume must be associated with the use of sufficient PEEP and alveolar recruitment maneuvers to keep the lung "open" and limit the formation of atelectasis. In addition to this optimization of mechanical ventilation, it is possible to reduce the impact of mechanical stress on the lung. The prone position, for example, makes it possible to free from certain visceral and mediastinal constraints, to optimize the distribution of ventilation as well as the ventilation to perfusion ratios. Thanks to the technological progress of intensive care beds, it is now possible to verticalize ventilated and sedated patients in complete safety. Verticalization could reduce the constraints imposed to the lungs, by reproducing the more physiological vertical station, and thus modifying the distribution of ventilation. Indeed, in two physiological studies published in 2006 and 2013 in Intensive Care Medicine, 30 to 40% of patients with ARDS appeared to respond to partial body verticalization at 45° and 60° (in a semi-seated or seated position). In addition to improving arterial oxygenation, verticalization appeared to decrease ventilatory stress, related to supine position, and increase alveolar recruitment, with improved lung compliance and end-expiratory lung volume (EELV) over time. Nevertheless, 90° verticalization has never been studied, nor have positions without body flexion (seated or semi-seated). In these studies, only patients with the highest lung compliance appeared to respond. These data support the current hypothesis of subgroups of patients with ARDS with different pathophysiological characteristics (morphological and phenotypic) and therapeutic responses. The investigators hypothesize that verticalization of patients with ARDS improves ventilatory mechanics by reducing the constraints imposed on the lung (transpulmonary pressure), pulmonary aeration, arterial oxygenation and ventilatory parameters. The first objective is to study the influence of the bed position of the patient with early ARDS on the variations in respiratory mechanics represented by the transpulmonary driving pressure (ΔPtp). The second objective is to evaluate changes in ventilatory physiology, tolerance and feasibility of verticalization in patients with early ARDS.

The global pandemic COVID-19 has overwhelmed the medical capacity to accommodate a large surge of patients with acute respiratory distress syndrome (ARDS). In the United States, the number of cases of COVID-19 ARDS is projected to exceed the number of available ventilators. Reports from China and Italy indicate that 22-64% of critically ill COVID-19 patients with ARDS will die. ARDS currently has no evidence-based treatments other than low tidal ventilation to limit mechanical stress on the lung and prone positioning. A new therapeutic approach capable of rapidly treating and attenuating ARDS secondary to COVID-19 is urgently needed. The dominant pathologic feature of viral-induced ARDS is fibrin accumulation in the microvasculature and airspaces. Substantial preclinical work suggests antifibrinolytic therapy attenuates infection provoked ARDS. In 2001, a phase I trial 7 demonstrated the urokinase and streptokinase were effective in patients with terminal ARDS, markedly improving oxygen delivery and reducing an expected mortality in that specific patient cohort from 100% to 70%. A more contemporary approach to thrombolytic therapy is tissue plasminogen activator (tPA) due to its higher efficacy of clot lysis with comparable bleeding risk 8. We therefore propose a phase IIa clinical trial with two intravenous (IV) tPA treatment arms and a control arm to test the efficacy and safety of IV tPA in improving respiratory function and oxygenation, and consequently, successful extubation, duration of mechanical ventilation and survival.

Inhalation of toxic gases and chemical irritants during the fire leads to damage to the respiratory tract or the alveolar tissue, which is known as smoke inhalation injury. Acute Respiratory Distress Syndrome (ARDS) is associated with smoke inhalation injury. These patients usually need physiotherapy in the form of chest mobilization and breathing exercises for up to 4 to 6 weeks after discharge from the burns care centre. The patients during this phase are usually in pain and extremely anxious about these exercises. Virtual reality distraction (VRD) is one such technique that is gaining immense popularity recently, it has more immersive distraction when compared to traditional distraction techniques. This study aims to investigate the effect of a virtual reality distraction (VRD) technique as a pain alleviation tool for reducing pain during physiotherapy in burns patients with acute respiratory distress syndrome (ARDS) in a hospital setting.

In this study, 120 patients with Acute Respiratory Distress Syndrome (ARDS) will be included on a two years-period in an intensive care unit (Assistance Publique des Hôpitaux de Marseille, France). Those patients will benefit from a blood test at inclusion in order to measure several coagulation biomarkers, including EV-TF. Subsequently, these patients will be treated according to the usual practices of the department, following recommendations. Patients who received an injected CT scan between Day 5 and Day 28 will be divided into two groups based on the presence or absence of a pulmonary embolism on imaging. The measured values of EV-TF levels and other studied biomarkers will be compared between these two groups in order to detect a possible association between them and the diagnosis of pulmonary embolism. It should be noted that patients receiving an injected CT-scan between Day 5 and Day 7 will be included in the main analysis while those receiving it between Day 8 and Day 28 will be included in the secondary analysis. Others will be excluded from any analysis. At the same time, several collections of clinical data will be carried out: on Day 1, Day 7, Day 28, and on the day of the CT scan if it is performed at another time.

Barotrauma (pneumothorax, pneumomediastinum) is a well-described complication of Acute Respiratory Distress Syndrome (ARDS), especially in patients with coronavirus disease 2019 (COVID-19) (16.1% in COVID-19, and about 6% in non-COVID-19 ARDS). Macklin effect was recently discovered by our group as an accurate radiological predictor of barotrauma in COVID-19 ARDS; the Investigators also found that density histograms automatically extracted from chest CT images provide a reliable insight into lung composition . Since lung frailty is a major issue also in non-COVID-19 ARDS, the Investigators want to confirm the predictive role of Macklin effect also in this setting. In addition, the Investigators aim to explore inflammatory profiling to decipher different biological aspects of the same clinical issue. Finally, the Investigators want to develop a specific management algorithm for patients diagnosed, according to our findings, with a specific ARDS sub phenotype characterized by increased lung frailty

Inhalation injury become a more common cause of death in burn patients but alone the smoke injury has low mortality rate. It is reported that a combination of smoke injury with cutaneous burn increases the mortality rate and predispose to Acute Respiratory Distress Syndrome. This experimental study aims to report the benefits of postural drainage on the respiratory system in burn patients. This study will determine the effects of postural drainage on oxygen saturation, airway clearance in burn patients with Acute Respiratory Distress Syndrome by comparing mechanical ventilation with and without the application of postural drainage. A randomized clinical trial will be conducted in the data and will be collected from the ICU of Jinnah Burn & Reconstructive Surgery Centre and Shafique Aziz Free Burn Centre through consecutive sampling through technique on 50 patients which will be allocated through sealed opaque enveloped into Group A and Group B. Pre and post treatment value of oxygenation and other variables for both group will be recorded by using APACHE II. Group A will be treated by postural drainage and mechanical ventilation for two consecutive days. Similarly, Group B will be treated by mechanical ventilation only. Data will be analyzed using SPSS software 25. After assessing the normality of data by the Shapiro-Wilk test, it will be decided either parametric or non-parametric tests will be used within a group or between two groups.

Mechanical respiratory support of preterm neonates with respiratory distress syndrome (RDS) and/or apnoea of prematurity (AOP) might be associated with adverse effects due to positive pressure (barotrauma), excessive gas delivery (volutrauma) or inadequate volume (atelectrauma). Asynchrony between patient efforts and ventilator support increases patient discomfort, favouring "fighting" the machine, and increases the risk of air trapping and lung overdistension even in patients with non-invasive ventilation (NIV). Recently, a new modality of synchronization has been available for pediatric and neonatal use: the neurally adjusted ventilatory assist (NAVA), which uses the diaphragmatic electrical activity (Edi) as a signal to start the rise in pressure of the ventilator, and to adjust the tidal volume and the inspiratory time (cycling off) to the patient needs, breath by breath. The aims of this study are to know whether NIV-NAVA compared to unsynchronized modalities (nCPAP/nIPPV), in infants born < 32 weeks GA with respiratory distress syndrome or requiring prophylactic NIV (immaturity, apnoea) reduces systemic inflammation, measured by serum cytokines concentration, reduces the need for oxygen and respiratory support, and if it increases the probabilities of survival without bronchopulmonary dysplasia (BPD).
