In this pilot study the feasibility of performing a larger trial to study the non-inferiority of High Flow Nasal Oxygen compared to non-invasive ventilation in patients with acute acidotic hypercapnic exacerbation of COPD wil be investigated
NCT06014034
Purpose of research:to explore a reasonable programmed withdrawal process of noninvasive ventilation and thereby reduce the duration of noninvasive mechanical ventilation in patients with acute exacerbations of chronic obstructive pulmonary disease.
NCT04448236
This is a randomised controlled trial of the blood flow restriction resistance exercise (BFR-RE) for early rehabilitation of chronic obstructive pulmonary disease acute exacerbation (COPDAE) in the Haven of Hope Hospital. BFR-RE was invented by Dr. Yoshiaki Sato in Japan 40 years ago. This exercise was newly introduced to the Physiotherapy Department of Haven of Hope Hospital in March, 2020 and not a routine common training in Hospital Authority. However, currently the "BFR-device" is in its 3rd generation. Under the guidance of a certified physiotherapist, a "low load intensity" can be used for resistance training to build up muscle mass and strength by applying the device over the thigh to partially limit the blood flow to the distal limb. BFR-RE is well studied in athletes, elderlies and patients for rehabilitation after orthopaedics surgeries. A large amount of literature reveals BFR-RE with "low load intensity" shows comparable increase of muscle mass as "high load intensity" resistance training and more increase of muscle strength than those only undergoing "low load intensity" resistance training. The objective of this study is to investigate the additional effects of 2-week BFR-RE in patients with COPDAE on top of the conventional in-patient rehabilitation training. The primary outcome is effect on localized muscle strength. The secondary outcomes include mobility function, systemic muscle strength as reflected by handgrip strength(HGS), health related quality of life, unplanned readmission to acute hospital rate within 1 month for COPDAE.
NCT05563493
Chronic obstructive pulmonary disease (COPD) is the leading cause of morbidity and mortality worldwide, a respiratory disease characterized by chronic airflow limitation that is not completely reversible. Impaired pulmonary functions, decreased exercise capacity and quality of life and increased dyspnea perception is prevalent in patients with acute exacerbations of COPD.It was demonstrated exercise training has beneficial effects in patients with acute exacerbations of COPD. The purpose of this study to evaluate the effects of chair-based exercise training on exercise capacity, respiratory functions, dyspnea, balance, depression anxiety and quality of life in COPD patients in acute exacerbation.
NCT03255057
This study evaluates the safety and efficacy of using the Hemolung RAS to provide low-flow extracorporeal carbon dioxide removal (ECCO2R) as an alternative or adjunct to invasive mechanical ventilation for patients who require respiratory support due to an acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD). It is hypothesized that the Hemolung RAS can be safely used to avoid or reduce time on invasive mechanical ventilation compared to COPD patients treated with standard-of-care mechanical ventilation alone. Eligible patients will be randomized to receive lung support with either the Hemolung RAS plus standard-of-care mechanical ventilation, or standard-of-care mechanical ventilation alone.
NCT05019911
Millimeter wave radar will be used to conduct non-contact monitoring continuously for patients' vital signs (eg. respiratory rate, heart rate, and chest/abdominal movement). The monitoring information will be transmitted to the central system through network and displayed in real time. Comparison with polysomnography will be done to examine the consistency between the two devices in diagnosing sleep breathing disorders. The predictive model of acute exacerbations of COPD will be established with the baseline indicators considered.
NCT04414891
Non invasive ventilation is the standard of care in managing patients with exacerbation of chronic obstructive pulmonary disease. However no optimal mode of NIV delivery is established; failure rates remain high, attributed to asynchrony and leak associated with NIV. Neurally adjust ventilator assist is a new mode that may improve patient ventilator interactions, improve synchrony and contribute to improved outcomes. Likewise ASV is a mode principled on the closed loop system and is associated with reduction of work associated with breathing and improved outcomes. In this randomised, non-blinded trial, we study these two modes of NIV delivery in patients of AECOPD with hypothesis being that better synchrony with NAVA may translate to better clinical outcomes.
NCT04147104
A pragmatic randomised controlled trial to determine whether early Veno-Venous Extracorporeal Carbon Dioxide Removal (VV-ECCO2R) in mechanically ventilated patients with acute exacerbated Chronic Obstructive Pulmonary Disease decreases the days of invasive mechanical ventilation.
