Filter by:This clinical trial is conducted within the research project 'Computerized Lung Sound Analysis'. The research goal is the development of a system enabling the automatic classification of lung sounds, which will result in a decision support system for physicians. The objective of this trial is to create a small lung sound corpus, enabling the development of a prototype of the described system. Therefore, investigators record lung sounds with several lung sound transducers distributed on the posterior chest of human test subjects.
The purpose of this study is to study interactions between genes, lifestyle environmental factors like foods, nutritional supplements and non-invasive medical devices and health factors that can be measured without specialized medical equipment in order to develop lifestyle recommendations tailored to individual genetics for a host of common chronic health conditions.
The purpose of this study is to evaluate the efficacy and adverse effect of nebulized corticosteroid to prevent post-extubation stridor in children.
This is a single-centre, open label study, aiming to evaluate the efficacy of beclomethasone dipropionate applied for 12 weeks with a dose of 400 µg twice a day (total dose 800 µg nebulized), on airway resistance and reactances (measured with Rint and FOT techniques) in children with recurrent wheezing, aged 2-5 years. In addition, clinic score as frequency of symptoms and exacerbations, will be assessed.
Acute dyspnea (shortness of breath) is a common complaint for patients presenting to the Emergency Department (ED). The chest radiograph (CXR) has been the mainstay in evaluating patients with shortness of breath and often provides the timely diagnosis of pneumonia, pneumothorax, pulmonary edema, among other primary diseases of the lung. There are limitations with chest radiograph such as large body mass (e.g, obesity) and patient positioning. On occasion, chest radiography findings are difficult to interpret. Lung ultrasonography may offer a means of clarifying ambiguous results. The objective of this study to determine the usefulness of point of care lung ultrasound in evaluating patients presenting to the ED with shortness of breath, cough and/or wheezing.
The primary objective of this study is to evaluate if Broncho-Vaxom® given to high risk infants for 10 days, monthly, for two consecutive years can increase time to occurrence of the first episode of wheezing lower respiratory tract illness (WLRI) during a three year observation period off therapy.
This study aims to assess the responsiveness to change of adventitious lung sounds (ALS) in patients with lower respiratory tract infection (LRTI). Patients will be recruited from a central Hospital and their demographic and anthropometric data, lung sounds, lung function, breathlessness, oxygen saturation and chest HRCT scan will be collected within 24h of the first appointment. Then, patients will be randomly allocated to either conventional treatment or conventional treatment plus respiratory physiotherapy. Conventional treatment will consist on daily medical treatment prescribed by the physician. Respiratory physiotherapy will involve 9 sessions (3 times a week during 2 weeks) of breathing retraining and chest clearance techniques, exercises for thoracic mobility, expansion and flexibility, cardiorespiratory exercise training and education about the disease. It is expected that ALS will be responsive to changes in patients' lung function after treatment. It is also expected that, by including a respiratory physiotherapy component in the treatment of patients with LRTI, they will express more improvements in a shorter period of time.
The effect of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD) has been based on systemic outcome measures, however, little is known about the effectiveness of this intervention on patients' lung function. The forced expiratory volume in one second (FEV1), despite of being the gold standard for assessing lung function in COPD, is poorly responsive to pulmonary rehabilitation. Thus, an objective and responsive outcome measure to assess the effect of pulmonary rehabilitation on lung function is needed. Computerized respiratory sounds have been found to be a more sensitive indicator, detecting and characterizing the severity of respiratory diseases before any other measure, however its potential to detect changes after pulmonary rehabilitation has never been explored. Therefore, this study aims to assess the effects of pulmonary rehabilitation on the characteristics of computerized respiratory sounds in patients with COPD. A randomized controlled study with one group undergoing pulmonary rehabilitation (n=25) and other group receiving standard care (n=25) will be conducted. The pulmonary rehabilitation program will included exercise training (3*week) and psychoeducation (1*week). Computerized respiratory sounds, lung function, exercise capacity, quadriceps muscle strength, health-related quality of life and health services use will be assessed in both groups, at baseline, immediately post-intervention and at follow-ups (3 and 6 months after PR). Descriptive and inferential statistics will be used. It is expected that significant changes occur on the characteristics of computerized respiratory sounds in patients enrolled in the pulmonary rehabilitation group, in comparison with patients receiving standard care. Thus, computerized respiratory sounds could provide a simple, objective and non-invasive measure to assess lung function changes after pulmonary rehabilitation.
The present study was aimed at investigating the efficacy of nebulizing Budesonide sin comparison with intravenous Dexamethasone before extubation in prevention of post-extubation complications amongst patients admitted in intensive care unit. In this double-blind randomized clinical trial study, 90 patients (age between 18 to 65) who are intubated (at least for 48 hours) and now are ready for extubation will be enrolled in the study after obtaining a written informed consent from their parents or guardians. The investigators divide our patients randomly into two equal groups. -In the budesonide group patients underwent a therapy with nebulizing Budesonide at a dose of 1 mg diluted in 4 cc of sterile water for 20 minutes, one hour preceding extubation. After extubation patients received nebulizing budesonide via oxygen mask at the same dose every 12 hours for 48 h.i In dexamethasone group intravenous dexamethasone was administered to patient at a dose of 0.15 mg/kg before extubation. After extubation, the administration of intravenous Dexamethasone continued at the same dose every 12 h. for 48 h. Another anesthesiologist who is unaware about kind of medication, will evaluate the patients for severity of stridor. We will record the vital sings and grade of stridor every 6 hour. Respiratory rate (RR), heart rate (HR), blood pressure (BP) and oxygen saturation (SPO2) were recorded for each patient immediately before aerosol administration (time 0) and at 30 and 60 min; and 2,4,8,12,24,36 and 48 hrs. After extubation then the presence of stridor (heard with the aid of stethoscope) was recorded within 48 hr of extubation
The aim of this study is evaluation of the effect of administration nebulized budesonide after extubation. The specific objectives of our study are to determine whether multiple doses of nebulized budesonide are effective to reduce or prevent postextubation edema. In this double-blind randomized clinical trial study, 70 patients (age between 18 to 65) who are intubated (at least for 48 hours) and now are ready for extubation will be enrolled in the study after obtaining a written informed consent from their parents or guardians. The investigators divide our patients randomly into two equal groups. -Patients who are in budesonide group will receive nebulized budesonide (1 mg-every 12 hours; n=35) and patients in placebo group receive placebo (normal saline; n=35) until 48 hours after extubation. If patient have extubation criteria the investigators will extubate him and for 24 hours after, another anesthesiologist who is unaware about kind of medication, will evaluate the patients for severity of stridor. We will record the vital sings and grade of stridor every 6 hour. Respiratory rate (RR), heart rate (HR), blood pressure (BP) and oxygen saturation (SPO2) were recorded for each patient immediately before aerosol administration (time 0) and at 30 and 60 min; and 2,4,8,12,24,36 and 48 hrs. After extubation then the presence of stridor (heard with the aid of stethoscope) was recorded within 48 hr of extubation.
