Active clinical trials for "Dyspnea"

The purpose of this study is to determine the best initial test in patients admitted to the hospital complaining of chest pain.

The purpose of this study is to determine whether focused sonography of the heart, lungs and deep veins can increase the number of patients with respiratory symptoms correctly diagnosed in an emergency department.

Introduction: Chronic obstructive pulmonary disease (COPD) presents with a gradual reduction and little bitterness reversible airflow causing shortness of breath, chronic cough and sputum abnormal. Patients with COPD often suffer exacerbations of their symptoms, particularly dyspnea, causing hospital admissions. Recent studies have shown that acupuncture stimulation transcutánea (AcuTENS) Dingchuan point (EX-B1) could help reduce dyspnea in patients with COPD. Objective: The aim of this study was to evaluate the possible utility of adding to the usual treatment stimulation AcuTENS in COPD patients admitted with severe dyspnea. Methodology: Patients who agree to participate will be randomly divided into two groups. The intervention group will receive a daily treatment, during the period of hospitalization, 45 minutes stimulation at acupuncture point AcuTENS Dingchuan (EX-B1), while the control group performed the same procedure with a device TENS simulated. The extent of dyspnea in both groups as well as the number of days of hospitalization and the number of drugs consumed.

This study is designed to compare three ultrasound-based aeration scores that were previously validated in specific populations, and to assess their correlation with computed tomographic measurement of pulmonary aeration in a population with different pathologies. Hypothesis: The "Loss of Aeration Score" will be more accurate than a simplified version and another widely used score, the "Lung Ultrasound Score".

SHORTIE is a two-phase study to determine the impact of the Triage Profiler S.O.B. (Shortness Of Breath) Panel on patient management, outcome, and cost.

A comparison of chest x-ray (CXR) and Minimum dose CT (MnDCT) in the acutely ill patient. The hypothesis is that MnDCT is more sensitive than CXR in the detection of acute findings in the acutely ill patient.

The purpose of this study is to study the role of closing volume as a determinant of orthopnea in stable obese subjects. The investigators hypothesized that: (1) increase in closing volume in supine position would be greater in orthopneic than in non-orthopneic subjects, and (2) the relationship of change in closing volume to change in dyspnea with position would be dependent on expiratory flow limitation in the sitting position. In stable obese subjects, in sitting and supine positions, the investigators measured Borg dyspnea score, static lung volumes, expiratory flow limitation, and single-breath nitrogen expiration test, from which the investigators determined closing volume and closing capacity, slope of phase III, and opening capacity. Orthopnea was defined as any increase in the Borg score in the supine position from its value in the sitting position

RATIONALE: Losartan potassium may be effective in treating pulmonary fibrosis caused by radiation therapy in patients with non-small cell lung cancer. PURPOSE: This clinical trial is studying losartan to see how well it works in treating pulmonary fibrosis caused by radiation therapy in patients with stage I, stage II, or stage III non-small cell lung cancer.

Cancer patients with very difficult to control symptoms at the Abbotsford (AC) and Fraser Valley (FVC) Cancer Centers are referred and admitted to the Tertiary Palliative Care Units at the Abbotsford Regional Hospital and Cancer Center(ARHCC). For symptom management, patients are sometimes given midazolam continuously through a needle placed underneath the skin. While effective in symptom management, midazolam can be sedating, leaving patients unable to interact with loved ones in their last days. This study is a pilot project. Before proceeding to a full-scale study, a "pilot study" or "feasibility study" is often carried out first to test the design of a study, the likelihood of successful recruitment or the acceptability of the intervention to potential subjects. The basic idea is to find out whether it will be practical to proceed to a larger study that will include more subjects. This type of study involves only a small number of subjects and therefore the results can only be used as a guide for further larger studies. The investigators also will determine whether palliative care cancer patients taking a medication called dexmedetomidine would have improved rousability (more easily and fully awakened) and symptom control (pain, shortness of breath, nausea or confusion) compared with those taking standard of care which is receiving the medication midazolam. The use of dexmedetomidine in other clinical situations (in the Operating Room or Intensive Care Unit where the patient can still respond to the doctor) has been shown to be effective in symptom control and to provide a better degree of rousability to patients but has not been well studied in the palliative care environment.

To explore biological mechanisms in human model of induced dyspnea, in order to remove the source of dyspnoea, to modify cerebral impact and to allow the development of targeted therapies.
