Active clinical trials for "Respiratory Distress Syndrome, Newborn"

The purpose of this study is to identify the safest dose of recombinant surfactant protein D (drug name: rfhSP-D) that can be administered to preterm infants born at less than 28 weeks gestation, and to help identify whether this can prevent the development of neonatal chronic lung disease.

Dyspnea is defined by a subjective sensation of respiratory discomfort, the intensity of which varies according to the terrain, the anamnesis and the cause. Resuscitation is associated with many causes of dyspnea, including initial distress, mechanical ventilation, or after-effects following the pathology and its management. Respiratory distress is the most severe form of impaired lung function. It is the first cause of hospitalization in intensive care. This distress, indicative of the failure of the respiratory system, is always severe and potentially fatal. It therefore constitutes an absolute therapeutic emergency. Dyspnea is often the revealing symptom of the condition and the urgency surrounding its management is an additional factor of concern for the patient. As a result, dyspnea is a pejorative element associated with severity or even death. In patients surviving the initial condition, dyspnea persists and can be found months or even years later, despite the initial rehabilitation. It is strongly associated with anxiety or even the fear of dying and contributes to the occurrence of post-traumatic stress syndromes. This persistent sensation of respiratory discomfort, limiting the patient's autonomy in his activities of daily living, seems to be able to reduce his quality of life. In addition, the perpetuation of this dyspnea could favor a spiral of deconditioning causing a progressive deterioration of the cardio-respiratory system justifying new hospitalizations. In patients with chronic respiratory failure, exercise rehabilitation supervised by hysiotherapists allows, in addition to improving autonomy, a significant reduction in dyspnoea, thus increasing the quality of life of these patients. The main objective of this study is to evaluate the effect at 2 years of 3 modes of management of dyspnea: exercise rehabilitation, standard physiotherapy and "usual care" on post-resuscitation dyspnea in patients with presented with severe COVID-19.

Despite almost universal usage of supplemental oxygen therapy in patients presenting in the emergency department with traumatic brain injury (TBI), optimal oxygen levels are unclear. The investigators propose a pilot multi-center randomized controlled trial to test the hypothesis that maintaining intermediate normal as opposed to high normal oxygen levels in patients presenting in the emergency department with TBI is feasible, and to obtain preliminary data on the efficacy of the two approaches to oxygen therapy. The aim is that the investigators produce pilot data, which could inform the design of potential subsequent larger clinical trials.

In the current COVID-19 pandemic, many patients have an acute respiratory distress syndrome (ARDS). Among mechanisms related to COVID-19 acute respiratory distress syndrome, cytokine storm and secretion of IL-6 play a central role. ARDS management involves intubation for protective mechanical ventilation, deep sedation and curarisation. During intensive care unit (ICU) hospitalization, improvement of hematosis induces a switch from a controlled ventilation mode to a withdrawal ventilation mode, such as Spontaneous Ventilation with Pressure Support (SP-PS) or Adaptative Support Ventilation (ASV). This step is essential prior to considering complete weaning from controlled ventilation and sometimes ends with a failure. In this case, deterioration of hematosis and/or ventilatory mechanics is observed. At the same time as withdrawal failure, the investigators observed biological inflammatory rebound in some patients. Therefore, influence of inflammatory biological parameters, including IL-6, on withdrawal failure, needs to be investigated. To this end, the investigators decide to dose different inflammatory markers - such as IL6, C-Reactive Protein (CRP), Procalcitonin (PCT) - in patients with acute respiratory distress syndrome due to COVID-19, during standard of care. Indeed, in patients with acute respiratory distress syndrome not due to COVID-19, the increase in IL6 is a negative prognosis during medical first aid but also when the mechanical ventilation is withdrawn. In addition, IL6 rise is associated with poor prognosis for patients with COVID-19 and longer stays in intensive care.

Thirty -one confirmed Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2 ) infected patients with Acute Respiratory Distress Syndrome (ARDS) and placed in prone position(PP) for 3 times (PP1, PP2, PP3)consecutively will be included. Arterial blood gases (ABG), partial pressure of arterial oxygen/ fraction of inspired oxygen (PaO2/FiO2 ) ratios, partial pressure of carbondioxide (PaCO2), positive end expiratory pressure (PEEP), and fraction of inspired oxygen (FiO2) values will be recorded before (bPP), during (dPP)and after (aPP) every prone positioning. Eye, skin, nerve and tube complications related to prone positions wll be recorded

The purpose of this study is to test if visualizing the heart with cardiac MRI/echo will be important in the understanding cardiac function and prediction of cardiopulmonary symptoms, physical effort tolerance, and outcomes in COVID-19 survivors. If successful, the research will allow us to identify the causes of lasting cardiopulmonary symptoms and begin developing cardiac and lung directed therapies accordingly.

Background:The impact of the emergence of SARS-CoV-2 variants on the severity and clinical outcomes of COVID-19 is controversial. Whether virological characteristics including the mutational patterns of the different viral proteins (e.g., Spike, NSP proteins, ORF6) could be associated with a different immune response and subsequent severity of the disease is unknown. ln the next coming months, new variants carrying the same or new mutational patterns will continue to emerge. Monitoring their dynamics over time and their impact on disease severity is required for refining national and international disease control policies. Main objective: To unravel the relationships between specific viral mutations/mutational patterns and the clinical outcomes of COVID-19 in patients hospitalized in intensive care units (ICUs) for acute respiratory failure following severe SARS-CoV-2 infection. Design of the study Prospective multicentre observational cohort study Schedule for the study: Inclusion period: 24 months; Participation period: 28 days ; Total duration : 24 months + 28 days;

ARDS is an acutely induced respiratory failure characterized by the appearance of bilateral alveolar opacities on imaging and hypoxemia Etiologies are divided into two classes: pulmonary, including all infectious pathologies, aspiration pneumonia, and drowning, and extra-pulmonary, induced by sepsis or acute pancreatitis. The mortality rate of ARDS remains high in unselected patient populations Among strategies that have proven beneficial in terms of patient outcome, prone positioning (PP) is associated with the greatest impact in terms of reduction in mortality. PP is currently recommended in the European guidelines for ARDS associated with a PaO2/FiO2 ratio < 150 mmHg in patients in whom ventilatory settings have been optimized beforehand, The failure of early PP studies to demonstrate a survival benefit in ARDS was attributed to insufficient session duration. The PROSEVA study was the first to demonstrate that a PP duration of 17 h is associated with a reduction in mortality During the COVID-19 pandemic, several centers have reported the implementation of longer PP sessions. Two strategies have emerged from these studies. In one case, the patient was left in the prone position until the criteria for stopping PP were met. Thus, the PP/supine position alternation was completely suppressed. In another published strategy, PP sessions were maintained for a period covering two nights. Furthermore, in a multicenter retrospective study, PP sessions were maintained until clinical improvement was associated with reduced mortality. In this study of 263 patients, the median duration of PP in the extended duration group was 40 h, and 75% of the sessions lasted 48 h or less. Using a propensity score, the authors showed that patients treated with an extended PP duration had a lower 3-month mortality rate than patients in the standard duration group . This protocol was also associated with a 29% cumulative incidence of pressure sores, similar to the 25% cumulative incidence reported in the PROSEVA study Other data published on pressure sores and PP of duration > 24 hours are also reassuring. Finally, a recent review recently reported that an extended PP session of > 24 h had also been used before the COVID-19 pandemic. PP sessions had a median duration of 47-78 hours and were applied mainly to ARDS secondary to community-acquired pneumonia. All pre-COVID studies were retrospective, monocentric, without a control group.

This study seeks to define the ultrasound profile of patients with COVID-19, and document the progression of these ultrasound findings to develop prognostication and clinical decision instruments that can help guide management of patient with COVID-19. Primary aims include the development of ARDS, refractory hypoxemia, acute cardiac injury, pulmonary embolism, pneumothorax or death. Secondary aims include potential change in CT and plain film utilization given the use of POCUS, as well as emergency department and inpatient LOS (length of stay).

The purpose of this study is to explore the question: Does prophylactic administration of exogenous surfactant in the delivery room, using a minimally-invasive technique, improve outcome in preterm infants 22-29 weeks' gestation compared to rescue treatment using the same technique?
