Early Inhaled Nitric Oxide for Respiratory Failure in Newborns
InfantNewborn8 moreThis prospective, randomized controlled trial tested whether initiating iNO therapy earlier would reduce death and reduce the use of extracorporeal membrane oxygenation (ECMO) -- temporary lung bypass -- therapy compared with the standard recommendation threshold. Infants who were born at >34 weeks' gestation were enrolled when they required assisted ventilation and had an oxygenation index (OI) >15 and <25 on any 2 measurements in a 12-hour interval. Infants were randomized to receive either early iNO or to simulated initiation of iNO (control). Infants who had an increase in OI to 25 or more were given iNO as standard therapy. The neurodevelopment of the subjects were evaluated at 18-22 months corrected age.
Impact of Non-invasive Ventilation in Hypercapnic COPD
CopdChronic Obstructive Pulmonary Disease3 moreChronic obstructive pulmonary disease (COPD) is a highly prevalent condition worldwide and is a cause of substantial morbidity and mortality. Unfortunately, few therapies have been shown to improve survival. The importance of systemic effects and co-morbidities in COPD has garnered attention based on the observation that many patients with COPD die from causes other than respiratory failure, including a large proportion from cardiovascular causes. Recently, two high profile randomized trials have shown substantial improvements in morbidity and mortality with use of nocturnal non-invasive ventilation (NIV) in COPD patients with hypercapnia. Although the mechanisms by which NIV improves outcomes remain unclear, the important benefits of NIV might be cardiovascular via a number of mechanisms. In contrast to prior trials of NIV in COPD that did not show substantial benefit, a distinguishing feature of these encouraging recent NIV clinical trials was a prominent reduction of hypercapnia, which might be a maker or mediator of effective therapy. Alternatively, improvements might be best achieved by targeting a different physiological measure. Additional mechanistic data are therefore needed to inform future trials and achieve maximal benefit of NIV. Recent work in cardiovascular biomarkers has identified high-sensitivity troponin to have substantial ability to determine cardiovascular stress in a variety of conditions - even with only small changes. In COPD, a number of observational studies have shown that high-sensitivity troponin increases with worsening disease severity, and that levels increase overnight during sleep. This biomarker therefore presents a promising means to study causal pathways regarding the effect of NIV in patients with COPD. With this background, the investigator's overall goals are: 1) To determine whether the beneficial effect of non-invasive ventilation might be due to a reduction in cardiovascular stress, using established cardiovascular biomarkers, and 2) To define whether a reduction in PaCO2 (or alternative mechanism) is associated with such an effect.
Nebulized Heparin for COVID19-associated Acute Respiratory Failure
Covid19The objective of the current study is to investigate the utilization of nebulized heparin to circumvent pathologic changes in COVID-19 and prevent harmful effects possible with systemic anticoagulation.
Correlation of Peak Tidal Inspiratory Flow Measured Before and After Extubation in Adult Patients...
Hypoxemic Respiratory FailureIn this study, patients who are ready for extubation and indicated for high-flow nasal cannula therapy after extubation will be enrolled, the investigators would measure the patient peak tidal inspiratory flow (PTIF) pre and post extubation to explore the correlation between the two PTIFs. Moreover, different HFNC flows would be applied, to explore the patient response in terms of oxygenation and lung aeration to different flow ratios that matched and are above post-extubation PTIF.
Prone Positioning in Awake Patients With COVID-19 Requiring Hospitalization
Respiratory FailureCOVID-19Acute respiratory distress syndrome (ARDS) is a major complication among patients with severe disease. In a report of 138 patients with COVID-19, 20% developed ARDS at a median of 8 days after the onset of symptoms, with 12.3% of patients requiring mechanical ventilation. Efficacious therapies are desperately needed. Supportive care combined with intermittent prone positioning may improve outcomes. Prone positioning (PP) of patients with severe ARDS (when combined with other lung-protective ventilation strategies) is associated with a significant mortality benefit. In addition, PP for >12 hours in severe ARDS is strongly recommended by clinical practice guidelines. The aim of this study is to compare the outcomes of prone positioning versus usual care positioning in non-intubated patients hospitalized for COVID-19.
Dociparstat for the Treatment of Severe COVID-19 in Adults at High Risk of Respiratory Failure
Coronavirus Disease 2019 (COVID-19)Acute Lung Injury1 moreThis was a randomized, double-blind, placebo-controlled Phase 2/3 study to evaluate the safety and efficacy of dociparstat sodium in adult patients with acute lung injury (ALI) due to Coronavirus Disease 2019 (COVID-19). This study was designed to determine if dociparstat sodium could accelerate recovery and prevent progression to mechanical ventilation in patients severely affected by COVID-19.
