Filter by:Acute lung injury is a highly prevalent disease in children, posing a serious threat to their health and causing economic burden on society and families. It has received high attention. Blocking the cascade immune inflammatory response that occurs in the respiratory tract and finding key targets for the prevention and treatment of acute lung injury has become an important challenge faced by the medical community. The pathogenesis of acute lung injury is complex, involving the combined action of multiple cells and cytokines in the immune system. Therefore, it is necessary to further study the function of immune cells and specific immune pathogenesis, providing new ideas and theoretical basis for clinical treatment of acute lung injury. The omics technology includes Genomics, Transcriptome, proteomics, metabolomics, etc. Through qualitative and quantitative analysis of changes in low molecular weight molecules or metabolites of biological samples, it provides a new way to find biomarkers and pathogenesis. We plan to study the peripheral blood of children with acute lung injury and healthy children, and use network analysis to screen for differential genes and related enrichment pathways in acute lung injury. We aim to explore the correlation between immune regulation and inflammatory repair in children with acute lung injury, and analyze the regulatory mechanisms between immune cells related to it. Provide assistance for clinical diagnosis and treatment.
Acute respiratory distress syndrome (ARDS) is a common acute and critical disease in clinic. The clinical mortality is as high as 30%-40%. At present, there is no specific treatment. Erythropoietin (EPO), also known as erythrocyte- stimulating factor, erythropoietin, has a certain amount in normal human body, mainly synthesized by liver in infants and kidneys in adults, which can stimulate erythropoiesis. In recent years, more and more studies have shown that high-dose exogenous EPO administration has benefit effects on multi-organ protection. Therefore, we designed this prospective, double-blind, placebo-controlled trial for defecting EPO on the alveolar fluid clearance of ARDS. The study mainly answers the following questions: Does human erythropoietin accelerate the resolution of alveolar edema in ARDS? Is there any effect on hospital survival? The study will draw conclusions by comparing the control group with the experimental group.
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.
This study focuses on patients who are at risk of developing a serious, life-threatening respiratory disease called Acute Respiratory Distress Syndrome (ARDS), which severely disrupts the function of their lungs. Preclinical studies have shown that the use of a volatile anesthetic agent such as Sevoflurane could be beneficial in the treatment and prevention of this respiratory condition. By improving gas exchange and attenuating pulmonary inflammation in particular, this agent would make it possible to prevent deterioration or to restore pulmonary function more rapidly. Half of the patients will receive inhaled sedation with sevoflurane and the other half will receive intravenous sedation already routinely used in participating ICUs (typically propofol, dexmedetomidine or a benzodiazepine, i.e. drugs approved for sedation). The aim of this study is to assess whether the use of Sevoflurane could be beneficial in the prevention of ARDS.
Investigation of the feasibility of monitoring processed transcutaneous electroencephalography (EEG), a method of interpreting brain activity, and near-infrared spectroscopy (NIRS), a method of determining levels of tissue oxygenation (StO2) in the brain, for patients with acute respiratory distress syndrome (ARDS) in the ICU.
Randomised, double-blind, placebo-controlled clinical trial to evaluate the efficacy of intravenous metoprolol in patients with Acute Respiratory Respiratory Distress Syndrome (ARDS).
Acute respiratory distress syndrome (ARDS) is a condition associated with hypoxemia due to noncardiogenic causes and results in high mortality. However, the epidemiology and treatment strategy for ARDS may have changed significantly due to the accumulation of a large body of knowledge, following the two-year pandemic of the novel coronavirus (SARS-CoV-2) of which the primary manifestation is ARDS. To improve the quality of ICU care that patients receive after admission to the ICU, a variety of academic societies, including the Japanese Society of Intensive Care Medicine and the Society of Critical Care Medicine, are currently developing evidence-based guidelines and consensus guidelines and statements regarding ABCDEF bundles, nutritional therapy, ICU diary. The ABCDEF bundle, nutritional therapy, and ICU diary have been developed and are being promoted for implementation in hospitals around the world. The implementation of evidence-based ICU care is strongly recommended, especially for patients with acute respiratory distress syndrome who frequently require ventilators to maintain their lives, because their patient outcomes are worse than those who were admitted to ICU with other causes. However, there is still little evidence on how the quality of ICU care (compliance rate) correlates with patient prognosis and outcomes, and there are currently no clear goals or indicators for the ICU care we should develop. This study aims to investigate the epidemiology and treatments given to the patients and evaluate the implementation of evidence-based ICU care and its association with the outcomes of patients with acute respiratory distress syndrome admitted to the ICU. The contents of mechanical ventilation settings, respiratory conditions, and the evidence-based ICU care, such as analgesia, sedation, rehabilitation, and nutrition, given to the patients will be collected in a daily basis. Aim 1: Epidemiology Aim 2: Treatments Aim 3: Evidence-based ICU care Aim 4: ARDS related Post Intensive Care Syndrome
Ventilator-induced diaphragmatic dysfunction and intensive care unit (ICU)-acquired weakness are two consequences of prolonged mechanical ventilation and critical illness in patients with acute respiratory distress syndrome (ARDS). Both complicate the process of withdrawing mechanical ventilation, increase hospital mortality and cause chronic disability in survivors. During transition from controlled to spontaneous breathing, these complications of critical illness favor an abnormal respiratory pattern and recruit accessory respiratory muscles which may promote additional lung and muscle injury. The type of ventilatory support and positioning may affect the muscle dysfunction and patient-self-inflicted lung injury at spontaneous breathing onset. In that regard, ARDS patients with ventilator-induced diaphragmatic dysfunction and ICU-acquired weakness who are transitioning from controlled to partial ventilatory support probably present an abnormal respiratory pattern which exacerbates lung and muscle injury. Physiological-oriented ventilatory approaches based on prone positioning or semi recumbent positioning with abdominal binding at spontaneous breathing onset, could decrease lung and muscle injury by favoring a better neuromuscular efficiency, and preventing intense inspiratory efforts and high transpulmonary driving pressures, as well as high-magnitude pendelluft. In the current project, in addition to perform a multimodal description of the severity of ventilator-induced diaphragmatic dysfunction and ICU-acquired weakness in prolonged mechanically ventilated ARDS patients, prone positioning and supine plus thoracoabdominal binding at spontaneous breathing onset will be evaluated.
Acute lung injury and ARDS (acute respiratory distress syndrome) are characterized by lung inhomogeneity, leading to a different distribution of the tidal volume (and pressure) within the lung. The quasi-static PV curve is a useful bedside tool to set mechanical ventilation, but it reflects a global behaviour of the lung. The electrical impedance tomography (EIT) is a non-invasive and radiation-free tool, monitoring dynamic changes in gas distribution. Images from EIT can be divided in several regions of interest, allowing to measure regional changes in compliance. The regional derived-EIT PV curve could provide valuable information on airway closure and AOP (airway opening pressure). Recent studies suggest that AOP measured by the ventilator seems to correspond to the AOP of the lowest injured lung. The investigators will perform one pressure-volume (PV) curve with a low-flow insufflation of 5 L/min starting from 0 cmH2O to a maximal airway pressure corresponding to the plateau pressure. During the low-flow insufflation, both ventilator and EIT-derived PV curves will be recorded. All PV curves will be analysed offline by the investigator to detect complete and regional airway closures, and measure AOPs.
Acute Respiratory Distress Syndrome (ARDS) is a syndrome characterized by respiratory distress and refractory hypoxemia caused by pulmonary and extra-pulmonary factors. Despite improvements in diagnosis and treatment in recent years, the mortality rate of severe ARDS is still around 40%. The distribution of lung lesions in ARDS patients is significantly gravity-dependent. Even with lung-protective ventilation strategies, tidal volume is concentrated in the ventral lung region, leading to ventilator-associated lung injury. Prone position ventilation can increase ventilation to the dorsal lung tissue and improve the ventilation-perfusion ratio, thus improving oxygenation. During prone position ventilation in ARDS patients, lung-protective ventilation strategies should be maintained, but with different respiratory mechanics from the supine position, requiring adjustment of ventilator parameters. Electrical Impedance Tomography (EIT) technology can be used for bedside monitoring of mechanically ventilated patients, providing real-time feedback on the patient's ventilation status and having great potential for clinical applications. Investigators believes that EIT monitoring during prone position ventilation in ARDS patients can individualize lung-protective ventilation strategies, minimize alveolar overdistension and collapse, improve the weaning success rate of invasive ventilation, and ultimately improve patient prognosis.
