Active clinical trials for "Respiratory Insufficiency"

Tracheal intubation (TI) is associated with a high risk of adverse events in critically ill patients and peri-intubation hemodynamic collapse is the most commonly observed. The primary aim of the PREVENTION trial is to compare the effect of the pre-emptive use of noradrenaline versus no peri-intubation use of noradrenaline on incidence of cardiovascular collapse following TI in adult critically ill patients. Patients with absolute indication or contraindication to vasopressor support will be excluded from this trial. Patients will be randomized 1:1 to a continuous infusion of noradrenaline started before induction titrated according to baseline mean arterial pressure. The primary outcome will be the incidence of cardiovascular collapse. Secondary outcomes will include lowest systolic blood pressure and cardiac arrest within 30 minutes from intubation.

This research aims to investigate the role of daily measurement of urinary cell cycle arrest markers and other serum and urinary biomarkers to predict the development of acute kidney injury in critically ill patients with COVID-19 and acute respiratory disease.

Health care renunciation is a factor that can alter patients' health status and increase the costs of its support. To date, there is no national data on the renunciation of care. This study will initially characterize the different forms of health care renunciation in patients with chronic respiratory diseases, treated with continuous positive airway pressure (CPAP) or non-invasive ventilation (NIV) , and analyze it impact on treatment compliance and health processes. The follow-up of these patients during 5 years will define renunciation trajectories (transition from the state of "renouncing" to "non-renouncing" and vice versa) and their impact on treatment compliance. The investigators hypothesize that a patient becoming renounced on a given treatment also decreases his treatment compliance (CPAP or NIV ). The impact of the renunciation trajectory on the patient's follow-up in terms of hospitalizations and deaths will also be studied.

To understand if a progressive increase in end-tidal carbon dioxide (CO2) levels are heralding respiratory difficulties before desaturation measured from capnography in obstructive sleep apnea patients, with the use of nasal prongs, transcutaneous monitors, Capnostream, and Massimo technologies.

ECMO is associated with significant costs, risks and requires specialist training and expertise. EXCEL is a novel, high-quality, detailed prospective registry of patients requiring ECMO in Australia and New Zealand. The registry provides information on patient selection, complications, costs and patient reported outcome measures. EXCEL uses the Theoretical Domains Framework to identify evidence-practice gaps and explore barriers and enablers to tailor implementation of evidence

This study evaluates the effects of prone positioning on homogenization of ventilation.

This study aims to compare care provided by physiotherapists, combining respiratory care and early rehabilitation in intensive care unit, with standard care on the rate of acute respiratory failure within 7 days after extubation, in patients with high risk of extubation failure.

The goal of this study is to compare two different modes of noninvasive ventilation in hypercapnic respiratory failure. The investigators will compare AVAPS and BIPAP S/T and hypothesize that AVAPS will result in a decreased length of stay in the ICU or on telemetry. Currently, noninvasive ventilation is the standard of care for hypercapnic respiratory failure. However, the most effective mode for patients with hypercapnic respiratory failure is unclear.

The goal of this pilot randomized cross-over study is to compare the effect of a full-face mask with expiratory washout to a conventional full face mask on non-invasive ventilation (NIV) in patients with acute hypercapnic, and acute hypoxemic, respiratory failure. The main questions it aims to answer are: Does a mask with expiratory washout improve minute ventilation in patients using non-invasive ventilation compared with a conventional single-limb NIV mask How does a mask with expiratory washout affect respiratory variables compared with a dual-limb NIV mask. Participants already prescribed NIV will undergo 3 arms of the investigation in a randomized order: Single-limb NIV with investigation mask (with expiratory washout) Single-limb NIV with conventional mask Dual-limb NIV with conventional mask

Mechanical ventilation may be associated with ventilator-induced lung injury (VILI). Several respiratory variables have been employed to estimate the risk of VILI, such as tidal volumes, plateau pressure, driving pressure, and mechanical power. This dissipation of energy during ventilation can contribute to VILI through two mechanisms, stress relaxation and pendelluft, which can be estimated at the bedside by applying an end-inspiratory pause and evaluating the slow decrease in airway pressure going from the pressure corresponding to zero flow (called pressure P1) and the final pressure at the end of the pause (called plateau pressure P2). The choice of measuring the end-inspiratory airway pressure (PawEND-INSP) at a fixed, although relatively early, timepoint, i.e., after 0.5 second from the beginning of the pause, as prescribed by the indications of the Acute Respiratory Distress Syndrome (ARDS) Network, while assessing the risk of VILI associated with the elastic pressure of the respiratory system, may not reflect the harmful potential associated with the viscoelastic properties of the respiratory system. It is still unclear whether an PawEND-INSP measured at the exact moment of zero flow (P1) is more reliable in the calculation of those variables, such as ΔP and MP, associated with the outcomes of patients with and without ARDS, as compared to the pressure measured at the end of the end-inspiratory pause (plateau pressure P2). This multicenter prospective observational study aims to evaluate whether the use of P1, as compared to P2, affects the calculation of ΔP and MP. The secondary objectives are: 1) verify whether in patients with a lung parenchyma characterized by greater parenchymal heterogeneity, as assessed by EIT, P1-P2 decay is greater than in patients with greater parenchymal homogeneity; 2) evaluate whether patients with both ΔP values calculated using P1 and P2 <15 cmH2O (or both MP values calculated using P1 and P2 <17 J/min) develop shorter duration of invasive mechanical ventilation, shorter ICU and hospital length of stay and lower ICU and hospital mortality, as compared to patients with only ΔP calculated with P1 ≥ 15 cmH2O (or only MP calculated with P1 ≥ 17 J/min) and patients with both ΔP values calculated using P1 and P2 ≥ 15 cmH2O (or both MP values calculated using P1 and P2 ≥ 17 J/min).
