Active clinical trials for "Respiratory Distress Syndrome"

The histologic hallmarks of lung inflammation and in the extreme, acute respiratory distress syndrome (ARDS), include intense accumulation of inflammatory cells in the airspaces and interstitium, injury to alveolar epithelial and endothelial cells, loss of epithelial-capillary integrity and accumulation of edema fluid in the interstitium and airspaces. Accordingly, for alveolar repair to occur inflammation must be halted, debris and inflammatory cells removed, injured tissue cells replaced, and capillary barrier function re-established. Macrophages are key players in all of these. Here the investigators hypothesize that resident alveolar macrophages and recruited macrophages serve completely different functions, acting independently (i.e. division of labor) yet cooperatively (synergism).

Acute respiratory distress syndrome (ARDS) is due to diffuse and severe lung inflammation. Despite intensive research, few therapeutics have emerged and treatment is still mostly symptomatic. As lung microbiota seems to be associated with lung inflammation in numerous chronic respiratory diseases, this study aims to analyse the correlation between lung microbiota and mortality.

In this comparative prospective study, we aim to compare the classic Macintosh laryngoscope and the Mac Grath videolaryncoscope in ICU covid 19 patients recruiting intubation and invasive mechanical ventilation. patients meeting inclusion criteria were randomized in 2 groups: MacGrath and Macintosh. we collected anthropometric and intubation data among all patients, and the 2 groups were compared regarding the time for intubation, the need of alternative techniques to intubate and the impact on the oxygenation by recording the lowest SPO2.

This study uses the AirGo band to monitor changes in tidal ventilation in spontaneously breathing patients with COVID-19 associated respiratory failure. It aims to recognize patterns of ventilation associated with worsening respiratory failure in this patient population. If successful, this study will lead to the development of new robust methods for real-time, continuous monitoring of respiratory function in patients with respiratory failure. In turn, such monitoring methods may enable improvements in the medical management of respiratory failure and timing of interventions.

Acute respiratory distress (ARD) is one of the most frequent reasons for consultation and hospitalization in emergency medicine. The use of ultrasound methods as a diagnostic and clinical assessment tool in emergency medicine is increasingly important. As such, ultrasound is a simple, non-invasive means of assessing diaphragmatic function in the patient's bed. Several methods of ultrasound assessment of diaphragm function have been described. Among these different methods, the diaphragmatic excursion seems to have a better intra and interobserver reproducibility as well as a greater feasibility, in particular because of its speed of realization and its learning curve seeming faster in comparison with the measurement. of the thickening fraction. Measuring the diaphragmatic excursion could therefore ultimately represent a simple means of assessing respiratory function, both diagnostic and prognostic, in patients with acute respiratory distress in the emergency departments. The etiologies of acute respiratory distress in very elderly patients (i.e.> 75 years) admitted to the emergency reception service are multiple. To our knowledge, there is no data available in the literature on the prevalence of diaphragmatic dysfunction and its short- and long-term course in this category of patients. The main objective of this study is therefore to assess the prevalence of diaphragmatic dysfunction and its evolutionary kinetics in patients over the age of 75 admitted for acute respiratory distress in the emergency medicine department.

Acute respiratory distress syndrome (ARDS) has a very poor prognosis and high mortality. To improve the early diagnosis of ARDS, there is an urgent need for novel biomarkers of ARDS. This project aims to detect novel biomarkers from peripheral blood , which can improve the early diagnosis and develop a more efficient therapy to enhance ARDS patient survival rate. Clinical data and blood sample were recorded before treatment and after treatment. Acute Physiology And Chronic Health Evaluation III (APACHE III) scores were calculated at enrolment. Different kinds of lymphocytes from blood samples would be detected by flow cytometry ,which could be used for discovering high sensitivity and specificity ARDS biomarker.

The use of cardiopulmonary bypass (CPB) combined with one lung ventilation (OLV) allows to perform minimally invasive cardiac surgery (MICS) through small incisions. MICS is described to be associated with similar outcomes compared with conventional surgery. Although less invasive, MICS has not been reported to favorably impact the incidence of respiratory failure after surgery. The combination CPB and OLV may induce acute respiratory distress syndrome (ARDS). After CPB contact of blood components with the artificial surface of the bypass, lung ischemia reperfusion injury (LIRI) and operative trauma may trigger a systemic inflammatory response syndrome (SIRS). During OLV, ARDS can result from hyperoxia, hyperperfusion and ventilatory distress in the ventilated lung as well as from LIRI and operative trauma of the collapsed lung. Extravascular lung water (EVLW) includes all fluids in the lung except for those in the vascular compartment. An excess of EVLW may lead to respiratory insufficiency. This may be due to an increased hydrostatic intravascular pressure, as it occurs in cardiogenic pulmonary edema, and/or by an increase of lung endothelial and epithelial permeability, as in ARDS. The extravascular lung water index (EVLWI) assessed by the transpulmonary thermodilution technique may be a useful tool for accurate diagnosis of ARDS, and the pulmonary vascular permeability index (PVPI) may help in the differentiation between pulmonary edema due to an increase in the pulmonary capillary permeability versus an increase in the pulmonary capillary hydrostatic pressure. As both CPB and OLV may induce an excess of EVLW, the investigators hypothesize that patients after MICS with intraoperative combination of CPB and OLV may have higher EVLWI and PVPI than those who received either CPB or OLV alone.
