Filter by:This is an observational study in which data already collected from people with acute respiratory distress syndrome (ARDS) admitted to an intensive care unit (ICU) are studied. ARDS is a life-threatening condition in which fluid builds up in the lungs making breathing difficult. In observational studies, only observations are made without participants receiving any advice or any changes to health care. People who are admitted to ICU for serious illnesses, like ARDS, often experience new health problems during and after their ICU stays. These health problems that may include physical, mental, and/or emotional disorders, are called post-intensive care syndrome (PICS). Identifying these new health problems early can help people by timely treatments and care. In this study, researchers want to identify any health problems that arise after ICU admission in people with ARDS in the United States (US). To do this, researchers will collect information on health problems, treatments, medicines, and healthcare visits in people with ARDS, 1 year before and after an ICU admission. They will then look to see whether the health problems are in areas that have been described as the post intensive care syndrome (PICS). In addition, they will measure healthcare related costs in the one year after admission and compare it to the one year prior to admission. Researchers will also compare this information with data collected for people with pneumonia who did not require ICU admission. This will help them to identify any new health problems arising due to ICU stays. The data will come from participants' medical claims information stored in the Optum Clinformatics Data Mart database from 2016 to 2022. The claims data will only be collected for people in the US. Researchers will collect data from participants admitted to ICU for ARDS for a maximum of 1 year before and after their stay.
Influenza is still responsible for more than 650,000 deaths per year worldwide and no major improvements in patients' care has been made despite 50 years of research. Especially, there is no therapeutic strategy targeting the dysregulated host response. CXCR4-expressing neutrophils seem to be involved in the rupture of host resistance. The aim of this study is thus to compare the percentage of blood CXCR4-expressing neutrophils between influenza survivors and non-survivors.
The aim of the study is to see if endogenous exhaled Nitric Oxyde (eNO) concentrations measured are significantly higher in ARDS patients admitted in ICU ; compared to control subjects in good health with no lung disease or global inflammation, operated under general anesthesia (i.e. intubated and ventilated) for thyroid or parathyroid.
Open-label pilot study of early inhaled nitric oxide (iNO) for patients developing de novo pulmonary hypertension during Acute Respiratory Distress Syndrome (ARDS.) The study aims to determine whether iNO has possible hemodynamic and clinical benefits when given early in the course of ARDS to patients with evidence of elevated pulmonary artery pressure.
Postoperative pulmonary complications (PPCs) remain a frequent event after pump-on cardiac surgery and are mostly characterized by postoperative hypoxemia.These complications are significant contributors to prolonged intensive care unit admissions and an escalation in in-hospital mortality rates. The dual impact of general anesthesia with invasive mechanical ventilation results in ventilator-induced lung injury, while cardiac surgery introduces additional pulmonary insults. These include systemic inflammatory responses initiated by cardiopulmonary bypass and ischemic lung damage consequent to aortic cross-clamping. Contributing factors such as blood transfusions and postoperative pain further exacerbate the incidence of PPCs by increasing the permeability of the alveolo-capillary barrier and disrupting mucociliary functions, often culminating in pulmonary atelectasis. Protective ventilation strategies, inspired by acute respiratory distress syndrome (ARDS) management protocols, involve the utilization of low tidal volumes (6-8mL/kg predicted body weight). However, the uniform application of low tidal volumes, especially when combined with the multifactorial pulmonary insults inherent to cardiac surgery, can precipitate surfactant dysfunction and induce atelectasis. The role of pulmonary surfactant in maintaining alveolar stability is critical, necessitating continuous synthesis to sustain low surface tension and prevent alveolar collapse. The most potent stimulus for surfactant secretion is identified as the mechanical stretch of type II pneumocytes, typically induced by larger tidal volumes. This background sets the foundation for a research study aimed at assessing the safety and efficacy of incorporating sighs into perioperative protective ventilation. This approach is hypothesized to mitigate postoperative hypoxemia and reduce the incidence of PPCs in patients undergoing scheduled on-pump cardiac surgery.
Thorathic fluid content measurement using indirect cardiometry is required for prediction of Weaning from mechanical ventilation in cases of acute respiratory distress syndrome and its value in sucsess Weaning
The aim of our study is to compare between the effect of nebulized and intravenous injection of hypertonic saline 3% on the outcome of patients with acute respiratory distress syndrome.
Data comparing respiratory drive and effort in critically ill patients with acute respiratory distress syndrome associated to different severity of COVID-19 penumonia (CARDS) and to other risk factors are lacking. Objectives: To assess respiratory drive and effort of CARDS patients at the first transition from controlled to assisted spontaneous breathing. The second aim was the rate of a composite outcome including the need of higher level of sedation
Acute respiratory distress syndrome (ARDS) is a heterogeneous syndrome with similar clinicopathological feathers caused by different etiologies. Respiratory supportive strategies is the main ARDS management, and the guidelines recommend low tidal volume to improve clinical outcomes. To be note, overdistension can still occur even if using a tidal volume as low as 6 ml/kg, given the heterogeneous nature of the syndrome. Therefore, adjusting tidal volume level to less than 6ml/kg may reduce ventilator-induced lung injury (VILI) and thus improve outcomes, especially in patients with severe lung injury. Prone position is also an important management in severe ARDS. Prone position can improve ventilation-perfusion (V/Q) matching and reduce the risk of VILI by recruiting dorsal collapsed alveoli. Meanwhile, prone position has also been shown to improve hemodynamics. Recent studies have showed that prone position did not reduce duration of venovenous extracorporeal membrane oxygenation (VV-ECMO) and 90-day mortality in patients with ARDS who receive VV-ECMO with ultra-low tidal volume ventilation. Therefore, the effect of PP on ventilation and lung blood flow in ARDS patients treated with VV-ECMO wiht ultra-low tidal volume ventilation remains unclear.
We aim to prospectively assess the burden, management and therapeutic approaches and outcomes of acute respiratory failure requiring respiratory support, during the winter months in China. The purpose of this study is to provide new and current data on the disease burden of acute respiratory failure and ARDS. It will answer the following questions: - The frequency and disease burden of acute respiratory failure in China; - The incidence of ARDS based on the new global definition within this patient cohort. - The mortality of ARDS within this cohort, and how does this vary based on ARDS categories and severity. - The long-term outcomes (1-year mortality and survivor quality of life) of ARDS within this cohort. - The nature course of ARDS (different stages and severity of ARDS). - The respiratory support management strategies, such as recruitment maneuvers, prone positioning, ECCO2R, and ECMO. - The use of drugs during ICU stays, including glucocorticoid, anticoagulant, nitric oxide, sivelestat, Xuebijing, and ulinastatin. - The economical burden of acute respiratory failure within this patient cohort. - The impact of occupation, incomes and education levels on the incidence and mortality of ARDS.
