Active clinical trials for "Respiratory Insufficiency"

This study aims to establish the treatment scheme of Yiqi Huoxue Huatan granule for chronic obstructive pulmonary disease (COPD) with chronic respiratory failure (CRF), reducing mortality, improving quality of life and forming high quality evidence.

The objective of this study is to evaluate the efficacy of noninvasive ventilation with helmet in reducing endotracheal intubation rates in comparison with Noninvasive Ventilation (NIV) facemask among patients with Acute Respiratory Distress Syndrome (ARDS)

High-flow nasal cannula oxygen therapy(HFNC) has proved no significant difference compared with noninvasive positive pressure ventilation (NPPV) in preventing postextubation respiratory failure and reintubation in patients with acute hypoxemic respiratory failure.However, the efficacy of early postextubation sequential HFNC in COPD patients with hypercapnic respiratory failure is inconclusive.

Adequate sedation is of paramount importance to avoid stress and pain in mechanically ventilated patients. It is usually achieved by infusing sedatives (benzodiazepine) and analgesic (opiate) drugs. This combined sedation may not be sufficient in some instances. The aim of this study is to evaluate whether addition of a third substance, ketamine, allows the achievement of better sedation and avoids the use of neuromuscular blocking agents.

This is a randomized, randomized controlled trial to investigate the efficacy and safety of Neurokinin-1 Receptor (NK-1R) 80 mg orally given daily to treat cytokine storm causing inflammatory lung injury and respiratory failure associated with severe or critical COVID-19 infection. NK-1R is the receptor of Substance P (SP) and responsible for its functionality. Here, we propose that SP via its tachykinin receptor, NK-1R may cause inflammation in Covid-19 infection. It may initiate the cytokine storming via binding to its receptor NK-1 and many inflammatory mediators are released. If SP release is reduced by NK-1R antagonist, it may control the cytokine storming and hence the hyper-responsiveness of the respiratory tract through reduction in cytokine storming It may serve as the treatment strategy for Covid-19 infected patients. Patients fulfilling the inclusion criteria will be enrolled after giving consent. They wll be randomized to treatment with either NK-1R antagonist or placebo in addition to Dexamethasone as a standard treatment given to both groups for Covid-19 infection as per the protocol at the treating hospital. Inflammatory lab markers as detailed should be collected once per day in the morning, preferably at the same time every morning. All enrolled participants will have whole blood collected for whole genome sequencing.

The novel SARS-CoV-2 virus has quickly spread worldwide, with substantial morbidity and mortality. There is very limited understanding of the short- and longer-term inflammatory/immunological and clinical course. However, the investigators expect survivors from severe COVID-19 to experience persistent functional impairments, as demonstrated in prior studies of patients with acute respiratory distress syndrome (ARDS) and other acute viral illnesses. Notably, however, few studies have ever investigated the biologic mechanisms underlying these functional impairments. Understanding these features of COVID-19 will improve the ability to design acute therapies and recovery-focused interventions. To address these knowledge gaps, the investigators propose a two-center, 225 patient longitudinal prospective cohort study of hospitalized COVID-19 patients with acute respiratory failure. Researchers will perform an in-depth evaluation of inflammatory/immunological biomarkers, and physical, pulmonary, and neuropsychological clinical outcomes during hospitalization, and over 3-, 6-, and 12-month follow-up.

The purpose of this trial is to determine whether Prone Positioning (PP) improves outcomes for non-intubated hospitalized patients with hypoxemic respiratory failure due to COVID-19, who are not candidates for mechanical ventilation in the ICU. The investigators hypothesize that PP will reduce in-hospital mortality or discharge to hospice, compared with usual care for non-intubated patients with do-not-intubate goals of care with hypoxemic respiratory failure due to probable COVID-19.

Prospective, randomized, open-label clinical trial studying the treatment of new onset atrial fibrillation in critically ill patients with septic shock. Patients will be assigned to rhythm vs rate control strategies with various outcome measures assessed.

A retrospective, single centre observational study to validate use of the HACOR score (Duan et al, 2017) in determining efficacy of non-invasive ventilation in Covid-19 respiratory failure.

Around 20% of the patients requiring hospitalization for Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) develop hypercapnia, which is associated with an increased risk of death. Once Non Invasive Ventilation (NIV) has been initiated, a reduction in Respiratory Rate (RR) and improvement in pH within 4 h predicts NIV success. If pH <7.25 and RR >35 breath per minutes persist, NIV failure is likely. Worsening acidosis, after initial improvement with NIV, is also associated with a worse prognosis. In addition, it has been shown that delaying intubation in patients at high risk for NIV failure has a negative impact on patient survival. Hence, assessing the risk of NIV failure is extremely important. NIV has some limitations: a) intolerance, discomfort and claustrophobia requiring frequent interruptions; b) poor patient-ventilator synchrony, especially in presence of air leaks or high ventilatory requirements. Since removing carbon dioxide by means of an artificial lung reduces the minute ventilation required to maintain an acceptable arterial partial pressure of carbon dioxide (PaCO2), the investigators hypothesize that applying Extra-Corporeal CO2 Removal (ECCO2R) in high-risk AECOPD patients may reduce the incidence of NIV failure and improve patient-ventilator interaction. After the beginning of ECCO2R, NIV could be gradually replaced by High Flow Nasal Cannula Oxygen Therapy (HFNCOT), potentially reducing the risk of ventilator induced lung injury, improving patient's comfort and probably allowing the adoption of a more physiologically "noisy" pattern of spontaneous breathing.
