Active clinical trials for "Respiratory Aspiration"

Extubation failure (EF) is independently associated with excess mortality of critically ill patients. To avoid EF, critically ill patients being weaned from invasive mechanical ventilation (IMV) perform spontaneous breathing trial (SBT), which is the litmus test for determining the ability to breathe without a ventilator. Thus, the performance of the SBT during weaning from IMV to predict successful extubation is crucial. The investigators hypothesize that patients with EF increase arterial lactate concentration during SBT due to increased work of breathing and hypoxia. The aim of this study is to evaluate the performance of variation in arterial lactate concentration before and after SBT in predicting successful extubation in critically ill patients.

This proof-of-concept study is to assess the potential benefit of botulinum toxin for patients with sleep-related breathing disorders.

Objective: The aim of the study is to determine the effects of nasopharyngeal suction with negative and positive pressure on the pain level, respiratory parameters, and mucosal irritation in infants. Materials and Methods: This study was conducted as a posttest randomised controlled experimental research. The data were collected at XX Training and Research Hospital between January and November 2020. While the positive pressure suction method was applied to the experimental group, the negative pressure suction method was applied to the control group.

This single center, single ascending dose (SAD) and repeat dose study in healthy adults comprises 2 parts. Part 1 will consist of 6 SAD cohorts, in which different dose levels of sargramostim will be given by intravenous (IV) infusion, subcutaneous (SC) injection, or inhalation (IH) administration. Part 2 will consist of 1 repeat dose cohort in which sargramostim will begiven by SC administration. Blood samples for PK assessment will be collected before and over 24 hours after each study drug administration. Blood samples for PD assessment will be collected before and up to 14 days after drug administration in Part 1, as well as before the first and up to 14 days after the second drug administration in Part 2. Safety and tolerability will be assessed throughout the study. For Cohort 5 of Part 1 only, 3 subjects will provide a CSF sample for PK assessmen tonce after SC drug administration.

The aim is to study effectiveness of inspiratory muscle training as a part of exercise training in patients with Chronic Obstructive Pulmonary Disease (COPD) and if it adds to general exercise training program in regard to respiratory muscle strength, dyspnea, exercise performance and quality of life.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) causes various toxic effects in many body tissues, organs and systems such as immune, cardiovascular, pulmonary, gastrointestinal, neuroendocrine and musculoskeletal systems, liver, kidneys and skin.Available limited numbers of studies showed that inspiratory muscle weakness in allo-HSCT candidates and recipients. Although meta-analysis, systematic reviews and studies demonstrated beneficial effects of inspiratory muscle training on several outcomes in different disease groups; chronic obstructive pulmonary disease, bronchiectasis and heart failure, no published paper reported the effects of IMT in allo-HSC recipients.

In our study, it was aimed to evaluate the effect of inspiratory muscle training on fear of movement due to dyspnea in COPD patients. Participants will be randomly assigned to two groups. Inspiratory muscle training in the training group will be administered at least 5 days a week, 15 minutes twice a day, beginning at 30% of the MIP for 8 weeks. Patients will come to the control once a week, the MIP values will be re-measured and the new training intensity will be determined at 30% of the new value. For the control group, a fixed training session will be given for at least 5 days a week, 15 minutes twice a day, not exceeding 15% of the MIP for 8 weeks.

Two important mechanisms play a major role in the pathogenesis of type 2 diabetes: insulin resistance of the target tissues and the impaired insulin secretion from pancreatic β-cells. Postprandial factors (such as insulin) are perceived by the human brain and induce signals that regulate glucose metabolism via the parasympathetic nervous system. Deep breathing exercise can increase parasympathetic nerve activity. Heart rate variability (HRV) in healthy people can be significantly increased by deep breathing maneuvers, indicating a shift from sympathetic activity to parasympathetic activity. The hypothesis is that this postprandial shift results in a change in peripheral glucose metabolism. In turn, the increased parasympathetic activity could potentially result in a change in postprandial insulin sensitivity or secretion. To test this hypothesis, this study investigates the effect of deep breathing exercise versus normal breathing on insulin sensitivity, on insulin secretion, glucose tolerance, resting energy expenditure, and on parasympathetic tone (analysis of heart rate variability).

The purpose of this study is to examine the acute effects of nicotine free electronic cigarette aerosol on vascular function in healthy, non-smokers. This study comprises a portion of a larger study comparing results of vascular function in nonsmokers to vascular function in healthy smokers chronically exposed to nicotinized electronic cigarette aerosol versus conventional cigarettes.

This study was carried out to determine the effect of breathing exercise performed during peripheral intravenous catheter (PIVC) application on pain, anxiety and patient satisfaction. The study was completed as a randomized controlled experimental study with a total of 130 individuals who met the inclusion criteria. The Descriptive Characteristics Questionnaire, the State-Trait Anxiety Inventory, and the Numerical Rating Scale were used to collect the data of the study. In addition, Algometer (66 Lb/30 Kg) device was used to evaluate the pain pressure threshold in determining the individuals to be included in the research sample. The individuals in the intervention group were given diaphragmatic breathing exercise while applying the catheter, and the individuals in the control group were inserted without any application.
