Using TEE to Evaluate the Effect of Levosimendan on Patients With ARDS Associated With RVD During...
Transesophageal EchocardiographyAcute Respiratory Distress Syndrome1 moreAcute respiratory distress syndrome (ARDS) is often complicated by right ventricular dysfunction (RVD), Acute cor pulmonale is the most serious form of ARDS complicated with RVD.Levosimendan is indicated for short-term treatment of acute decompensated heart failure that is not responding well to conventional therapy and requires increased myocardial contractile force.In 2016, the European Society of Cardiology issued recommendations for the management of acute right heart failure, stating that levosimendan can improve right ventriculo-pulmonary artery coupling by both increasing right heart contractility and reducing pulmonary vascular resistance.However, the clinical application of levosimendan in the treatment of ARDS right heart dysfunction is insufficient.Therefore, this study intends to use transesophageal ultrasound to evaluate right ventricular function, reduce the limitation of poor right ventricular window in transthoracic echocardiography, and conduct a multi-center randomized controlled study to further explore the effects of levosimendan on right ventricular function in ARDS patients, such as tricuspid ring systolic displacement (TAPSE) and tricuspid ring systolic displacement velocity (S '). Effects of right ventricular area change fraction (RV FAC), right ventricular end-diastolic area/left ventricular end-diastolic area (RVEDA/LVEDA), pulmonary circulation resistance (PVR), hemodynamics and mortality.
Pressure Opening With Electrical Impedance Tomography
Acute Respiratory Distress SyndromeAcute Lung InjuryAcute 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.

Explore Potential Plasma and BALF Immunometabolic and Lipidomic Biomarkers for Identifying ARDS...
Acute Respiratory Distress SyndromeAcute Respiratory FailureAcute respiratory distress syndrome (ARDS) is a life-threatening condition that causes high mortality (41% to 58%). Previous studies have reported that biomarkers can facilitate phenotypic diagnosis of ARDS, enabling precision treatment of ARDS. Although there were many studies that found some potential therapeutic targets for ARDS, no pharmacotherapies have been validated to treat ARDS. The development of biomarkers to predict the prognosis and monitor the response to treatment would be of interest for selecting patients for specific therapeutic trials. Many recent studies have shown that immune metabolic changes are involved in the pathogenesis of ARDS and may become a new therapeutic target for them. We aimed to identify a panel of immunometabolic and lipidomic biomarkers derived from blood and bronchoalveolar lavage fluid (BALF) which may help differentiate the ARDS endotypes.
Use of hUC-MSC Product (BX-U001) for the Treatment of COVID-19 With ARDS
COVID-19ARDS1 moreThis is a phase 1/2a study including 2 parts, phase 1 and phase 2a. The phase 1 part is an open-label, single-arm, dose-escalating study to evaluate the safety and explore the dose limiting toxicity and maximum tolerated dose of a human umbilical cord derived mesenchymal stem cell product (BX-U001) in severe COVID-19 pneumonia patients with acute respiratory distress syndrome (ARDS). Qualified subjects after the screening will be divided into low, medium, or high dose groups to receive a single intravenous infusion of BX-U001 at the dose of 0.5×10^6, 1.0×10^6, or 1.5×10^6 cells/kg of body weight, respectively. The Phase 2a part is a randomized, placebo-controlled, double-blind clinical trial examining the safety and biological effects of BX-U001 at the appropriate dose selected from phase 1 for severe COVID-19 pneumonia patients with the same inclusion/exclusion criteria as the phase 1 part.

Neutrophil Elastase Inhibitor in Treatment of ARDS Patients With Mechanical Ventilation Caused by...
Acute Respiratory Distress SyndromeSepsis is a life-threatening organ dysfunction caused by the host's maladjusted response to infection. It is one of the common clinical critical diseases, often accompanied by multiple organ failure, immune imbalance and high mortality. Sepsis is a syndrome of physiological, pathological and biochemical abnormalities caused by infection. Its incidence rate and prevalence have been on the rise in the past few years. Sepsis has greatly endangered the lives and health of the public. Among them, ARDS is a fatal complication of sepsis and a common critical illness syndrome in ICU. At present, the conventional treatment for ARDS caused by sepsis is still limited to indirect supportive therapy such as primary disease treatment, infection control, mechanical ventilation support, and nutrition improvement, lacking specific direct treatment methods. So far, the drug treatment effect of ARDS at home and abroad is not satisfactory. Therefore, it has become an urgent task to find a new treatment strategy to alleviate ARDS. Neutrophil elastase inhibitors can reversibly and competitively inhibit the release of neutrophil elastase, inhibit the activation of neutrophils and the infiltration of inflammatory cells in the lungs, alleviate the release of inflammatory mediators, and thus improve respiratory function, which has a good protective effect on various experimental ARDS. However, the efficacy of neutrophil elastase inhibitor represented by sivelestat sodium in the treatment of ARDS has reached a relatively consistent positive conclusion in animal experiments, while the results of clinical studies are different. These differences in clinical research still need further analysis, research and verification in clinical trials. At present, the clinical studies of neutrophil elastase inhibitors in the treatment of sepsis induced ARDS are very few, and there is a lack of related prospective randomized controlled clinical studies. Therefore, further prospective clinical trials are needed to evaluate the therapeutic effect of neutrophil elastase inhibitors on sepsis induced ARDS patients. This study is intended to determine whether neutrophil elastase inhibitor can reduce the mechanical ventilation time, Murray lung injury score, ICU hospitalization time and 28-day mortality of septic ARDS patients compared with the control group through a single center randomized controlled trial, so as to provide a new basis for the treatment strategy of septic ARDS patients.

The ICU LIBERATION Study
Acute Respiratory Distress SyndromePost Intensive Care Syndrome2 moreAcute 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.
