Filter by:The aim of the study is to examine the air dispersion pattern and the environmental influence of open airway suction in general ward setting. Secondly, the study is aimed at identifying a simple & practical enclosure device in general ward. Suction will be performed in manikin in supine lying. Nasopharyngeal suction will be performed by physiotherapist with working experience more than 1 years. Besides, surgical mask & enclosure tent will be adopted as the enclosure barrier device in this study. Research Question 1. To assess the extent of the environmental contamination during coughing and simulated airway suction 2. To measure the air particle count during coughing and simulated open airway suction. 3. To evaluate how effective the enclosure barrier in reducing the air particle dispersion during open airway suction.
Chronic cough is one of the most common complaints in respiratory specialty clinics, imposing significant economic burden on patients and severely affecting their quality of life. Currently, the pathogenesis of chronic refractory cough remains incompletely understood, and treatment remains a major challenge in clinical practice. Cryotherapy treatment via bronchoscopy has shown efficacy in certain airway diseases, but there is currently no research reporting its effects on chronic refractory cough. The goal of this clinical trial is to learn if Cryotherapy treatment works to treat individuals with chronic cough. It will also learn about The safety and effectiveness of the cryotherapy treatment system produced by Ningbo SensCure Biotechnology Co., Ltd.. The main questions it aims to answer are: - Does cryotherapy treatment lower the frequency and severity of cough and enhance quality of life? - Will there be safety or operational performance issues when using this cryotherapy treatment system? Researchers will compare cryotherapy treatment with no treatment to determine if cryotherapy treatment is effective for treating chronic cough. Participants will: - Take routine bronchoscopy examination, lavage, and mucosal biopsy ,with/without cryotherapy treatment locally (around the left and right main bronchi, upper trachea, and carina) - undergo a screening period of approximately 28 days. Follow-up visits and necessary examinations will be scheduled for the 3rd day after treatment initiation and at weeks 1, 2, 4, 8, and 12 thereafter. - Monitor vital signs and clinical manifestations.
Cough has previously been described by the type of cough you have ie such as wet, dry, and chesty, and also by its features such as how often you are coughing its,intensity, and severity, but never has the varying patterns of cough been studied in any detail and it could be that the pattern of the cough is closely related to patient-perceived intensity, frequency and most importantly severity. Cough is a symptom and like any other symptom (such as pain) the severity of it can only be gauged by the patient experiencing it. We have created a one-page brand newl questionnaire that shows 4 distinct cough patterns that we believe exist and an empty field designed so that patients can record a pattern of cough they experience which is not already a choice on the questionnaire. The questionnaire also records patients' experience of how frequent, and intense, the cough is, and how it disrupts their lives, on a 1-10 scale (Visual analogue scale), the sum of these scores is collated and this gives us a severity score. The first phase of the project is to determine whether 30 Chronic cough patients understand the questionnaire, and are able to complete it with little direction, and if the cough patterns we identified encompassed all pattern types. second part of the study is to look at how repeatable the questionnaire is when completed over a 6 week period.
After thoracic surgical intervention, patients often feel intense pain with respiratory movements reduction making coughing less effective. The air stacking improves peak of expiratory flow (PEF) and cough peak flow (CPF) in neuro myopathies, thus raising the hypothesis that may also be effective in patients undergoing thoracic surgeries. Objectives: To evaluate the effectiveness, safety and feasibility of air stacking on postoperative PEF and CPF in patients undergoing thoracic surgeries. Methods: Patients undergoing thoracic surgery underwent air stacking on 3th PO. Dyspnea, pain, SpO2, maximum inspirational pressure (MIP), maximum expiratory pressure (MEP), PEF and CPF were evaluated in pre and postoperatory.
This study is being done in order to understand what causes people to have a chronic cough, which is defined as a cough lasting for more than 8 weeks. The research team wish to find out whether there is any inflammation in the lungs of patients with chronic cough. The research team will also determine whether a suspected chemical produced in the body, called adenosine triphosphate (ATP) can be responsible for causing the chronic cough. In order to be able to find out what is abnormal in those who have a chronic cough, The research team will need to compare their results with those that do not have a chronic cough. In this study, the research team will examine 10 participants who suffer from chronic cough and 8 individuals who do not have a chronic cough and are healthy.
This study is a randomized controlled trial. Adult patients undergoing thyroidectomy under general anesthesia at Severance Hospital and Yonsei Cancer Center are included in tis study. For intervention group, patients receive anesthesia with total intravenous remimazolam, while for control group, patients receive anesthesia with inhalation anesthetic. The primary end point of the study is to determine whether coughing during endotracheal tube extubation is less when anesthesia is maintained with intravenous remimazolam compared to inhalation anesthetics. The secondary end points are cough score (graded into 4 levels), frequency of reoperation due to postoperative bleeding, These include the frequency of hypertension during the extubation process and whether additional painkillers are used in the recovery room.
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-designed phase 2 clinical trial to evaluate the efficacy, safety and pharmacokinetic (PK) characteristics of HS-10383 in Chinese adult subjects with refractory or unexplained chronic cough (RUCC).
The aim of this study is to investigate cervical region biomechanics, muscle performance and respiratory muscle strength in patients with Chronic Obstructive Pulmonary Disease (COPD) compared to healthy subjects.
The purpose of this study is to assess the effect of Hepatic impairment (HI) on the Pharmacokinetic (PK) profile and safety of Camlipixant.
This study is a multicenter, randomized, double-blind, placebo-controlled Phase Ib/II clinical trial to evaluate the effectiveness, safety, tolerability and pharmacokinetics (PK) of TCR1672 Tablets in patients with refractory chronic cough.
