Active clinical trials for "Lung Diseases"

The Erector Spinae Plane (ESP) block is a new interfascial regional anesthesia technique recently described by Forero et al. Currently the literature shows the ESP block being used for analgesia after thoracic surgery, breast surgery, abdominal surgery (visceral abdominal analgesia in bariatric surgery, ventral hernia repair, cholecystectomy), thoracic vertebral surgery and for pain relief in rib fractures. Taking in consideration the excellent clinical experience, but the lack of strong and high-quality evidence, supporting the use of ESP block for pain management in patients undergoing VATS procedures, there is a specific interest to develop a prospective study. Comparing the effect of the current pain relief strategy at the MGH (intercostal nerve block by the surgeon at the end of the procedure ) versus ESP block after VATS, seems warranted to improve current clinical results.

Although non-invasive positive pressure ventilation (NPPV) shows the good curative effect of treating the patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), some patients do not tolerate NPPV or do not benefit from it. High-flow nasal cannula (HFNC) is well tolerated and may be used to patients with AECOPD who are intolerant to NPPV treatment. This study is to evaluate the physiological effect of HFNC and compare it with NPPV.

The aim of this study was to investigate the safety and efficacy of Sintilimab (IBI308) in patients with resectable NSCLC, and to provide new treatment options for neoadjuvant therapy in patients with stage II-IIIA NSCLC

Chronic Obstructive Pulmonary Disease (COPD) is characterized by chronic airflow limitation, a qualification of impairment of respiratory muscle function, including hyperinflation and muscle weakness. Thus, pulmonary rehabilitation is indicated for patients and is recommended for even the most severe cases. However some patients do not conclude conventional rehabilitation protocols, due to exercise intolerance, are then an electrical estimation and muscle training respiratory adjuvant treatments for patients. and little has been explored about the effects and methodologies of using transcutaneous electrical diaphragmatic stimulation (TEDS) in healthy subjects. The objective of this study on stage I is to evaluate the acute effect of transcutaneous electrical diaphragmatic stimulation on respiratory muscle strength, cardiac variability, thickness, resistance, mobility and diaphragmatic activation comparing different frequencies of electrical stimulation in healthy individuals. The objective of this study on stage II is to evaluate the effects of transcutaneous electrical diaphragmatic stimulation, compared to inspiratory muscle training on respiratory muscle strength, security of the technics, thickness and diaphragmatic function in healthy individuals.The objective of this study on stage III is to evaluate the effects of transcutaneous electrical diaphragmatic stimulation, compared to IMT on respiratory muscle strength, lung function, thickness and diaphragmatic function in patients with exacerbated chronic obstructive pulmonary disease. The study was approved by the Research Ethics Committee of the Hospital de Clinicas of Porto Alegre (CAEE: 80271517.2.0000.5327).

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.

Inspiratory muscle training has been an important part of pulmonary rehabilitation program directed at patients with COPD. It can increase respiratory muscle strength, relieve dyspnea ,improve the quality of life in COPD patients. However, there is no uniform standard for the intensity of inspiratory muscle training. By comparing a series of indexes, such as maximal inspiratory pressure, maximal expiratory pressure, degree of dyspnea and exercise capacity before and after the training under different intensity, a large number of literatures have explored the appropriate intensity of inspiratory muscle training. But to date, there are few studies about the effects of different intensity of inspiratory muscle training on respiratory physiological mechanism. It has been shown that inspiratory muscle training may be more beneficial to improve the pulmonary rehabilitation effect of COPD patients with inspiratory muscle weakness. So it is not clear whether there is a difference in respiratory physiology between patients with normal inspiratory muscle strength and those with lower inspiratory muscle strength. Respiratory central drive, as an important physiological index, which can be reflected by minute ventilation volume, mouth pressure, mean inspiratory flow and diaphragm electromyography,is closely related to the symptoms and the severity of the disease.Therefore,the purpose of this study was to investigate the changes of respiratory mechanics and central drive in COPD patients at different inspiratory loads, and at the same loads between patients with and without respiratory muscle weakness.That can provide more evidential evidence for setting up the intensity of inspiratory muscle training.

Effects of standing at different angles on transpulmonary pressure

This study aims to objectively evaluate the clinical efficacy and safety of Traditional Chinese Medicine in the treatment of AECOPD Risk Window, providing a basis for the formulation of TCM treatment plan with AECOPD.

The purpose of the study is to investigate the addition of high frequency chest wall oscillation (HFCWO) therapy to the prescribed care regimen to support the diaphragm during airway clearance among post-COVID patients with COPD and chronic productive cough as a way to limit the advancement of pulmonary symptoms and need for critical services during recovery from COVID-19.
