Filter by:Point-of-care ultrasound in patients with dyspnoea has been shown to alter patient treatment and the time to correct treatment when performed in emergency departments. In Denmark, physician-staffed ambulances are sent to citizens with severe ABCD symptoms including dyspnoea. Hence, there is a potential for correct diagnostics and appropriate treatment already in the citizens' own home or en route to the hospital. This study aims to evaluate the clinical performance of prehospital point-of-care ultrasound in patients with dyspnoea.
The pilot/feasibility study evaluates the ability of High Velocity Nasal Insufflation (HVNI) therapy to facilitate ambulation and mobilization in patients experiencing shortness of breath, as compared to simple oxygen therapy.
Non-Invasive Mechanical Ventilation (NIV) has been increasingly used in the treatment of acute respiratory failure. Notwithstanding failure rates still remains high, ranging from 5% to 60%. The onset of delirium, agitation, pain and dyspnea may contribute to reduce the success rate of non invasive ventilation treatment. The aim of this study is to assess the incidence and impact of delirium, agitation, pain and dyspnea on clinical outcomes in a population of patient admitted to Respiratory Intensive Care Unit undergoing Non-Invasive Mechanical Ventilation for Acute Respiratory Failure.
Researchers are trying to test the effectiveness and feasibility of a multicomponent lifestyle intervention to support weight loss decreases dyspnea in obese people with chronic lung disease and clinically significant breathlessness.
Rationale: The most important complaint in severe COPD is dyspnea which is associated with a diminished exercise tolerance, reduced quality of life and can lead to anxiety and depression. If dyspnea continues to exist despite optimal therapy it is called refractory dyspnea. There is evidence that morphine is effective and can safely be prescribed for treating refractory dyspnea. However, a Dutch study recently showed that few pulmonologists actually prescribe opioids for this indication. The main reasons for this are concerns about side effects and respiratory insufficiency as well as negative emotions for the patient and families at the thought of using morphine. Most studies investigating opioids for treatment of dyspnea are conducted with morphine tablets, and only a part of these patients suffered from COPD. To our knowledge there has not been a randomized controlled trial investigating fentanyl patches for refractory dyspnea in COPD patients. However, studies comparing fentanyl and morphine in pain management show that patients may prefer fentanyl patches and have less problems with obstipation. Objective: There are three main objectives for this study. First, the investigators will investigate the following hypothesis: Both fentanyl and morphine provide a reduction of dyspnea which is better than placebo. Fentanyl has less side effects than morphine. Secondly, with this Dutch multi-center study the investigators would like to enlarge the evidence base and contribute to the experience with opioids for refractory dyspnea in COPD thereby greatly facilitating its implementation in the Netherlands. Finally, the investigators will develop and evaluate educational material about opioid use for dyspnea in COPD. Study design: This is a multi-center double blind, double-dummy cross-over randomized placebo-controlled trial with three study arms. A total of 60 COPD patients will be included in this study. Participants will be treated sequentially with three combinations of medication and/or placebo medication in a random order. They will receive either a Fentanyl patch in combination with placebo tablets, a placebo patch with Morphine Slow release tablets or a placebo patch with placebo tablets. Main study parameters/endpoints: The primary endpoint is change in dyspnea sensation Secondary endpoints are change in HR-QoL, anxiety, sleep quality, hypercapnia and the number and seriousness of side effect.
The performance of STIs and clinical scores alone and their combination to predict short term prognosis of acute decompensated heart failure.
The purpose of this study is to explore the role of low-dose immediate-release oral morphine as a novel adjunct pharmacotherapy to enable symptomatic adults with advanced chronic obstructive pulmonary disease (COPD) or interstitial lung disease (ILD) to exercise at higher intensities for longer durations and maximize the psycho-physiological benefits of a supervised exercise training program. We hypothesize that, compared to placebo, exercise training with oral morphine will result in relatively greater improvements in exercise endurance time and intensity ratings of perceived breathlessness during constant-load cardiopulmonary cycle exercise testing (CPET) at 75% of peak power output (PPO).
The investigators aim to make an overview of persistent dyspnea at the end of an hospitalization for a respiratory disease using an actual tool, the Multidisciplinary Dyspnea Profile questionnaire.
Pulmonary embolism, or clots blocking the blood vessels of the lungs, is a common clinical condition requiring treatment with blood thinners. In most patients, recovery is complete. A small proportion of patients, however, develop complications (high blood pressure in the lung circulation, i.e. pulmonary hypertension). Persisting breathlessness during activity is a common symptom in many of these patients and leads to a reduced ability to engage in daily physical activity. The reason for this activity-related breathlessness remains uncertain and is the main question of the proposed study. Using new sophisticated technology, the investigators will determine the root causes of perceived breathing difficulty. The investigators will test the idea that breathlessness is fundamentally the result of increased drive to breathe from control centers in the brain. The investigators will measure drive to breathe by measuring the electrical activity descending from the brain to the main muscle of breathing - the diaphragm. The investigators will discover if the increased drive to breathe is due to accumulation of carbon dioxide in the blood as a result of poor blood perfusion of areas of the lung due to the effects of blockage by clots. The investigators also will investigate whether weakness and fatigue of the muscles of breathing, as a result of the high breathing demands that are present in patients with blood clots in the lungs, contribute to breathlessness. With this information it is hopeful that better treatment options will be developed to relieve this distressing symptom.
Shortness of breath is very common among patients on dialysis for kidney failure; however, its causes are often not understood. This study will explore the lungs and the heart of these patients to determine the causes of shortness of breath. The amount of salt in the body tissues, which tends to accumulate in dialysis patients and can also cause shortness of breath, will also be measured. Machines that exploit magnetic resonance, ultrasound and x-rays to take images of the body interior will be employed; in addition, breathing tests, questionnaires and blood tests will also be used. 20 patients on dialysis will be recruited and have two visits: one at the beginning of the study and one year later to observe any changes in the lungs, heart and salt accumulation over time.
