Active clinical trials for "Dyspnea"

A growing body of physiological evidence now exists to support a potential role for inhaled cannabis in the medical management of adults with chronic obstructive pulmonary disease (COPD), particularly as it may related to improving pulmonary function, alleviating the symptom of breathlessness and improving exercise endurance. The purpose of this randomized double-blind crossover trials is to evaluate the efficacy and physiological mechanism(s) of action of inhaled vaporized cannabis targeted to relief of physical activity-related breathlessness and exercise endurance in symptomatic patients with severe-to-very severe COPD.

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.

The ancient use of acupuncture as a treatment modality of traditional Chinese medicine has also been proven effective in Western medicine. The use of this treatment tool for pain control is already proven in the literature and today is considered an important adjuvant for this purpose. However, the ancient texts of acupuncture also report the use of certain points to tonify organs functions, despite of pain control. According to these texts there are some points that allow the treatment of lung diseases improving respiratory function. In order to investigate the effects of stimulation of such points using electric field application, the effect of these procedure on pulmonary function and the impact of this practice on dyspnea symptoms, the investigators will conduct a randomized study with 60 patients (1: 1 randomization) distributed in 2 arms (intervention arm-BI and control arm-BC). Transcutaneous neural stimulation of acupuncture points of the BI patients will be performed. For the BC arm the investigators will place the electrodes over the points without turn on the device to produce a placebo effect. Pulmonary function test, Borg scale application and 6 min walk test will be performed before and after the intervention in each group for subsequent data comparison.

Evaluate the effect of upper limbs strength training versus the effect of upper limbs endurance training, on dyspnea, in patients with COPD during a pulmonary rehabilitation program.

In recent years the survival of cancer patients has increased exponentially. But together with that survival, and due to the different oncological treatments, side effects have also increased significantly. Some of these may be tumor asthenia or dyspnea. The latter can represent a serious health problem, with important limitations for individuals. To control this, we consider that the measures used in conventional clinical practice can be implemented, mainly developed through physical exercise. But we believe that not only this is enough, but we also propose an intervention with a comprehensive perspective from the rehabilitative approach, with the aim of integrating education and training of the oncological patient with dyspnea. We propose to combine the intervention with physical exercise with a re-education in the performance of activities of daily living, within a "Functional Oncological Re-education Program", to see if in this way better results are achieved in clinical practice. That is why we propose to verify the effects produced by the implementation of a multimodal physical exercise program with a specific autonomy recovery program in comparison with an isolated intervention through physical exercise on the functionality and physical performance in cancer patients with dyspnea . To do this, we proposed an experimental, prospective, randomized study using a parallel scheme of fixed assignment with an experimental group and a control group in patients from the Oncology Hospitalization Unit of the Salamanca University Hospital Complex. 44 participants with dyspnea, who were admitted at the time of inclusion, will be selected through a consecutive sampling. After the baseline evaluation, the participants will be randomized into two groups. The subjects of the experimental group will carry out a Rehabilitation Program in addition to the physical exercise carried out in all the participants. The main variable will be the performance of basic activities of daily living (Barthel scale) and the degree of dyspnea (mMRC scale). In addition, physical performance (SPPB), blood oxygen saturation (pulse oximetry), fear / avoidance of movement / TAMPA scale) and quality of life in cancer patients (ECOG) will be assessed. The results of this study could be transferred to the clinic, incorporating them into care protocols for cancer patients with dyspnea.

The principal aim of this study was to adapt pain neuroscience education to dyspnea, Dyspnea Neuroscience Education (DNE), and measure its effect on dyspnea perception, physica l activity level, disability, quality of life and ventilatory and functional capacity through a randomized controlled trial. The secondary objectives were to evaluate its feasibility and its effect on emotional state (anxiety and depression), medical atten dance, number of exacerbations and the willingness to exercise.

Breathlessness on exertion is a common and troublesome complaint of individuals with restrictive lung disorders. In these adults, breathlessness contributes to physical activity-limitation and avoidance and an adverse health-related quality-of-life, often in a self-perpetuating cycle. It follows that alleviating dyspnea and improving exercise tolerance are among the principal goals in the management of adults with restrictive lung disorders. Nevertheless, effective management of breathlessness and physical activity-limitation remains an elusive goal for many healthcare providers and current therapies (e.g., antifibrotic agents, oxygen, exercise training) are only partially successful in this regard. Thus, research aimed at identifying breathlessness-specific medications to complement existing therapies for the management of physical activity-related breathlessness in restrictive lung disorders is timely and both clinically and physiologically relevant. The purpose of this randomized crossover study study is to examine the acute effects of two doses of inhaled nebulized furosemide (a loop diuretic) on the perception of breathlessness during laboratory-based cycle exercise in healthy, young men in the presence of an external thoracic restriction to mimic a 'mild' restrictive lung deficit. To this end, the investigators will compare the effects of inhaled 0.9% saline placebo and inhaled furosemide (40 mg and 120 mg) on detailed assessments of breathlessness (sensory intensity and affective responses) and its physiological determinants (ventilation, breathing pattern, dynamic operating lung volumes, cardio-metabolic function) symptom-limited, high-intensity, constant-work-rate cycle exercise testing with external thoracic restriction sufficient to mimic a 'mild' restrictive pulmonary deficit in healthy, men aged 18-40 years.

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).

To evaluate the use of Incentive Spirometry in Non-critically Ill Hospitalized Patients With Shortness of Breath.

Post-lateral thoracotomies and assisted thoracic surgery (CTVA) are the main surgical approaches for pulmonary resections. One of the counterpoints of these surgical approaches is postoperative pain, which in addition to causing ventilatory changes and reduction of lung capacities, contributes to bed rest and consequent decrease in patients' functionality. These complications increase hospitalization time and hospital costs, being determinant factors for perioperative morbidity and mortality. In order to prevent these outcomes of reduce the functional capacity of patients, new physiotherapeutic approaches have been adopted, such as the use of the cycloergometer. Recent studies show that the early use of this device brings benefits such as: improved blood circulation and venous return, increased muscle strength, improved functional capacity and reduced symptoms of dyspnea and fatigue. This study aims to compare the effect of interval training with continuous cycle ergometer training on performance in the six-minute walk test. Randomized and controlled clinical trial performed with patients submitted to elective thoracic surgery, hospitalized at the intensive care unit (ICU) and in the hospitalization unit of the Hospital Pavilhão Pereira Filho of the Santa Casa de Misericórdia Brotherhood of Porto Alegre. Participants will be randomized into three groups: control group (CG), interval exercise group (GHG) and continuous exercise group (GEC). Functional capacity assessments will be performed through the six-minute walk test (6MWT) and the chair sit and lift (TSL) test in 30 seconds, and evaluation of the clinical state of fatigue through the revised Piper-Fatigue Scale. The evaluations will be performed preoperatively and at hospital discharge.
