Filter by:The novel SARS-CoV-2 virus has quickly spread worldwide, with substantial morbidity and mortality. There is very limited understanding of the short- and longer-term inflammatory/immunological and clinical course. However, the investigators expect survivors from severe COVID-19 to experience persistent functional impairments, as demonstrated in prior studies of patients with acute respiratory distress syndrome (ARDS) and other acute viral illnesses. Notably, however, few studies have ever investigated the biologic mechanisms underlying these functional impairments. Understanding these features of COVID-19 will improve the ability to design acute therapies and recovery-focused interventions. To address these knowledge gaps, the investigators propose a two-center, 225 patient longitudinal prospective cohort study of hospitalized COVID-19 patients with acute respiratory failure. Researchers will perform an in-depth evaluation of inflammatory/immunological biomarkers, and physical, pulmonary, and neuropsychological clinical outcomes during hospitalization, and over 3-, 6-, and 12-month follow-up.
COVID-19 may cause severe pneumonitis that require ventilatory support in some patients, the ICU mortality is as high as 62%. Hospitals do not have enough ICU beds to handle the demand and to date there is no effective cure. We explore a treatment administered in a randomized clinical trial that could prevent ICU admission and reduce mortality. The overall hypothesis to be evaluated is that HBO reduce mortality, increase hypoxia tolerance and prevent organ failure in patients with COVID19 pneumonitis by attenuating the inflammatory response.
A pilot multicentric randomized controlled study investigating the feasibility of recruiting 50 pulmonary fibrosis patients in acute respiratory failure within18 months. Additionally, exploratory efficacy and safety outcomes will be evaluated.
To demonstrate that a strategy involving early first-line enteral nutrition is associated with improved preservation of gut mucosa integrity, as assessed based on the plasma citrulline level at H72, compared to a strategy involving early first-line parenteral nutrition
Acute respiratory failure (ARF) is a frequent reason for consulting in the Emergency Department (ED) and one of the major clinical problems prompting admission in intensive care unit. In the ED, evaluation of an ARF is mainly based on clinical examination and frontal chest x-ray performed to the patient bedside. This practice has a limited diagnostic capacity due to a lack of specificity of clinical and radiological semiology, especially in the polypathological patient. Thoracic ultrasonography provides morphological information regrouped as a syndrome (interstitial syndrome, alveolar condensation, pneumothorax) and allows the identification of pleural effusions (PE). The PE diagnosis is easy, quick, and relies on two-dimensional ultrasound imaging. Compared to CT scan, which remains the reference examination although ill-suited in the context of emergency, thoracic ultrasonography has a sensitivity and specificity greater than 90% for pleural liquid (PL) diagnosis. In addition, thoracic ultrasonography is used to assess the volume of PL, determine its nature and guide the pleural puncture with higher performance than chest x-ray. The semi-quantitative evaluation of PEs has been validated in patients with mechanical ventilation hospitalized in intensive care unit. On the other hand, few data on the prevalence and quantification of PL for hospitalized patients in ED for an ARF are currently available. Thus, the objective of this study is to evaluate the prevalence and severity of the PL identified by thoracic ultrasonography in patients admitted to the ED for an ARF by emergency physicians with ultrasound skills recommended by the French Society of Emergency Medicine.
To evaluate the impact of enteral nutrition on microaspiration of gastric content and pharyngeal secretions
Rationale : Electric muscle stimulation reduced critical-illness related weakness in patients with severe sepsis and septic shock. But optimal protocol of the stimulation in unknown. Hypothesis: Focal muscle contraction may improved the muscle power and have systemic anti-inflammatory via cytokine secretion . The difference of electricity used in upper limb or lower limb stimulation may lead to different effect. Study design: Stratified randomized parallel control study, comparing Biceps, Quadriceps electric muscle stimulation vs. non-stimulation group. Participant: adult patients with severe sepsis and acute respiratory failure requiring mechanical ventilation. Intervention: daily stimulation of bilateral Biceps or Quadriceps by programmed electric devices 32 minutes, 5 days/week Outcome: 1. Primary outcome: Ventilator-dependent days 2. Secondary outcome: change of hand drip muscle power/interleukin-1b/interleukin-6/interleukin-8/TNF-alpha
Knowledge-based systems were initially developped to automatically adapt pressure support settings during invasive ventilation, and proved to be at least as efficient as experienced clinicians. Non-invasive ventilation has become the standard of care for patients suffering from acute hypercapnic respiratory failure (ARF)and has reduced the need for endotracheal intubation in these patients, thus reducing their hospital mortality. NIV success or failure is closely related to the tolerance of NIV treatment, which is tightly correlated to patient-ventilator synchrony. As severe asynchronies frequently occurs during NIV (namely in more than 40% of patients) and as the occurence of asynchronies is related to the use of high pressure support levels, to the presence of leaks and/or to non optimal expiratory trigger settings, very frequent ventilator settings adaptations should allow reducing patient-ventilator asynchronies but require the presence of an experienced clinician at the bedside during NIV treatment. A computer-driven ventilator settings adaptation has the adavantage of permitting very frequent ventilator settings adaptation whithout requiring the presence of an experienced clinician at the bedside and could possibly improve patient-ventilator interaction. The aim of the present study is to test the faisability of using the Smartcare NIV computer-driven system to automatically adapt ventilator settings during non invasive ventilation delivered because of acute respiratory failure.
The purpose of this study is to assess the hypothesis that, as compared to early intravenous feeding, early nutrition via the enteral route is associated with reduced Day 28-mortality in critically ill patients treated with mechanical ventilation and vasoactive drug.
The main objective of this study is to evaluate the efficiency of the oxygen therapy delivery system Optiflow® compared to 2 others standard oxygen therapy delivery systems (Ospal®, non invasive ventilation).12 immunocompetent patients will compare the successive use of oxygen therapy delivery systems Optiflow®/Ospal® and 12 immunodeficient patients will compare the successive use of systems Optiflow®/Non invasive ventilation.
