Long Term Follow up of Children Enrolled in the REDvent Study
Respiratory Distress SyndromeAdult4 moreThis is a prospective observational follow-up study of children enrolled in a single center randomized controlled trial (REDvent). Nearly 50% of adult Acute Respiratory Distress Syndrome (ARDS) survivors are left with significant abnormalities in pulmonary, physical, neurocognitive function and Health Related Quality of Life (HRQL) which may persist for years.Data in pediatric ARDS (PARDS) survivors is limited. More importantly, there are no data identifying potentially modifiable factors during ICU care which are associated with long term impairments, which may include medication choices, or complications from mechanical ventilator (MV) management in the ICU including ventilator induced lung injury (VILI) or ventilator induced diaphragm dysfunction (VIDD). The Real-time effort driven ventilator (REDvent) trial is testing a ventialtor management algorithm which may prevent VIDD and VILI. VIDD and VILI have strong biologic plausibility to affect the post-ICU health of children with likely sustained effects on lung repair and muscle strength. Moreover, common medication choices (i.e. neuromuscular blockade, corticosteroids) or other complications in the ICU (i.e. delirium) are likely to have independent effects on the long term health of these children. This proposed study will obtain serial follow-up of subjects enrolled in REDvent (intervention and control patients). The central hypothesis is that preventing VIDD, VILI and shortening time on MV will have a measureable impact on longer term function by mitigating abnormalities in pulmonary function (PFTs), neurocognitive function and emotional health, functional status and HRQL after hospital discharge for children with PARDS. For all domains, the investigators will determine the frequency, severity and trajectory of recovery of abnormalities amongst PARDS survivors after ICU discharge, identify risk factors for their development, and determine if they are prevented by REDvent. They will leverage the detailed and study specific respiratory physiology data being obtained in REDvent, and use a variety of multi-variable models for comprehensive analysis. Completion of this study will enable the investigators to identify ICU related therapies associated with poor long term outcome, and determine whether they can be mitigated by REDvent.

Glucocorticoid Therapy for Acute Respiratory Distress Syndrome
Acute Respiratory Distress SyndromeAcute respiratory distress syndrome (ARDS) is a clinical syndrome of inflammatory lung injury characterized by increased pulmonary vascular permeability, loss of aerated lung tissue, severe hypoxemia and impaired compliance. Despite the advance in the critical care technology, the mortality of ARDS remains high in the last decades. Glucocorticoids have profound anti-inflammatory actions through the pleiotropic effects of the glucocorticoid receptor, which are considering a promising pharmacological therapy to mitigate the inflammatory lung injury and subsequent fibrosis in ARDS. Previous clinical trials have repeatedly tested the efficacy of glucocorticoid therapy in ARDS; however, the data about hard outcomes, such as mortality, are inconsistent between these studies. Investigators designed a 3x2 factorial trial of glucocorticoid therapy in ARDS to test the effects of glucocorticoid dosages (dose 0, dose 0.5 mg/kg, and dose 1 mg/kg of methylprednisolone equivalence) and durations (prolonged and short duration) on the treatment efficacy. In addition, investigators will measure the change of inflammatory biomarkers for post-hoc analysis to explore whether biomarkers could be used to guide patient selection and steroid tapering.
Paramedical Protocol for Ventilation in Acute Respiratory Distress Syndrome
Acute Respiratory Distress SyndromeAcute respiratory distress syndrome (ARDS) is a frequent pathology in intensive care (around 10% of patients admitted to intensive care and almost a quarter of patients on mechanical ventilation) and a serious one, with a hospital mortality rate of 40%. The main measures that have an effect on mortality in ARDS involve adjustments to the ventilator, known as protective ventilation. In the most severe patients, adjuvant measures such as prone positioning and the use of curarisation in the initial phase of the disease can improve survival. All these measures have been included in the latest national and international recommendations. However, a vast observational study carried out in 50 countries revealed low compliance with these recommendations. More than a third of patients did not receive protective ventilation, and the majority did not receive prone positioning when this was indicated. During weaning from artificial ventilation, it has been widely demonstrated that replacing clinician judgement with the implementation of paramedical care protocols improved weaning and significantly reduced the duration of artificial ventilation. Therefore, investigators hypothesize that the implementation of a paramedical care protocol for ventilation in the acute phase of ARDS improves compliance with recommendations and thus reduces mortality and the duration of artificial ventilation. However, implementation of such a protocol requires operational training for all the nurses in the participating departments. Simulation appears to be the training method of choice, as it is a teaching technique that enables technical and non-technical skills to be passed on with good retention of what has been learnt, as well as assessing what has been learnt. To make it possible to train several dozen nurses within a tight timescale, a partially dematerialized simulation model incorporating innovative e-learning tools will be developed.

Inflammation During ECMO Therapy and ECMO Weaning
Acute Respiratory Distress SyndromeThe goal of this interventional clinical trial is to compare patients who undergo ECMO therapy for treatment of acute respiratory distress syndrome (ARDS) and a randomized into one of two possible weaning strategy groups. Group 1: Weaning from ventilator occurs before ECMO weaning. Group 2: Weaning from ECMO occurs before weaning from ventilator. This study investigates which one of these strategies is more indulgent for the lung, and leads to less inflammation and therefore less potential side effects and an overall more favourable clinical course. As a primary criterion, measure of IL-6 in blood samples will beused. As secondary criterions, SOFA score at various time points, ventilation pressures, lung injury score (LIS), length of stay in the intensive care unit, and ventilator-associated pneumonia as well as levels of inflammatory cells and cytokines in both blood samples and bronchoalveolar lavage at different time points will be determined.

Improvement of ARDS Ventilation-perfusion Matching by Prone Positioning Assessed by EIT
Acute Respiratory Distress SyndromeProne Position1 moreAcute Respiratory Distress Syndrome (ARDS) is a highly lethal disease with limited treatment options. In recent years, prone position ventilation has been shown to improve the mortality rate and lung injury of ARDS patients by promoting lung recruitment, improving ventilation/perfusion (V/Q) ratio, enhancing respiratory system compliance, promoting sputum drainage, and effectively avoiding overinflation of the dorsal lung. Electrical Impedance Tomography (EIT) technology has been used to evaluate the effect of prone position ventilation on lung V/Q matching, and some studies have confirmed that prone position ventilation can improve lung V/Q matching and oxygenation index. However, previous studies were mostly case reports or small-sample physiological studies that lacked dynamic changes in lung V/Q matching during repeated prone position ventilation. Therefore, this study hypothesizes that prone position ventilation can increase lung V/Q matching in ARDS patients, and its improvement is correlated with changes in oxygenation index, invasive ventilation time, and patient prognosis. Repeated prone position ventilation can maintain lung V/Q matching at a higher level, no longer affected by changes in body position, which can accelerate pulmonary function recovery and improve the prognosis of ARDS patients.
