Active clinical trials for "Sleep Apnea, Obstructive"

This Research studies for compare muscle strength among OSA patients who treat with myofunctional therapy program in Rajavithi hospital

Acetazolamide, a carbonic anhydrase inhibitor, has received some attention as potential treatment for obstructive sleep apnea (OSA). It produces a metabolic acidosis by excreting bicarbonate, thereby stimulating baseline ventilation. Evidence suggests that acetazolamide primarily improves ventilatory control instability (expressed as loop gain), which is an important contributor to the pathophysiology of OSA. Few studies have assessed the efficacy of acetazolamide in patients with OSA. Since most of them had a small sample size and used different therapeutic dosages, clinical applications are currently limited. Therefore, this study aims to compare the effect of two acetazolamide dosages on the severity and pathophysiology of OSA.

Study was planned to investigate the effect of pranayama on dyspnea, daytime sleepiness, cognitive function, quality of life, activities of daily living, functional exercise capacity, physical activity level, sleep quality, fatigue, musculoskeletal pain, depression and anxiety in OSAS.

Obstructive sleep apnea (OSA) is characterized by complete or partial upper-airway collapse during sleep associated with sleepiness. OSA causes severe impairments in quality of life (sleepiness, tiredness, concentration difficulties). Moreover, OSA has adverse consequences on the cardiovascular system by causing intermittent hypoxia, increased sympathetic nervous system activation and vascular endothelial dysfunction. Continuous Positive Airway Pressure (CPAP) and mandibular advanced devices (MAD) remain the two first-line therapies for OSA. However, not all patients are eligible for these treatments or are not able to follow for a lifelong therapy and therefore do not use it consistently. A recent meta-analysis has confirmed that regular physical activity reduces OSA by approximately 28% (Mendelson et al. 2018). However, an important inter-individual variability exists and no study to date has identified characteristics of patients who respond to these interventions. The aim of this Prospective study, single-site, non-randomized 4-week trial is to evaluate the impact of a 4-week physical activity intervention on the apnea-hypopnea index (AHI) in OSA patients based on their baseline fluid shift level. Participants included in the present study will benefit from a 4-week physical activity intervention. Upon the initial visit, a physical activity prescription will be defined and they will be equipped with a physical activity monitor that allows feedback. Participants will then exercise one day per week on-site and 4 days/week on their own. Weekly physical activity will be reviewed weekly with the participant during their on-site visit.

Background: Obstructive Sleep Apnea Syndrome (OSA) is a kind of sleep disorder. The symptoms are intermittent, partial or complete upper airway collapse, seriously impacting oxygen saturation and oxidative stress. Some patients choose to do upper airway surgeries, but the success rate is only 60-70%. The symptoms might relapse because of aging and gaining weights. The purpose of our study is to compare the effect of transoral robotic surgery (TORS) and oropharyngeal rehabilitation (OPR) on patients after TORS. Methods: Participants above 20 years old who are newly diagnosed with mild to severe OSA (Apnea-hypopnea Index >5/h), and the physician will explain the treatment programs to every subject in clinic. Expected results: The hypothesis of this study is the success rate of surgery will be enhance by increasing tongue and jaw-opening muscle strength after OPR. The biomarkers of cardiovascular disease may decrease and both the collapse of upper airway and sleep quality may be improved after TORS and OPR.

Clinical trial on the effect of continuous positive pressure (CPAP). Objectives: 1) To assess the total or partial recovery of oxidative and inflammatory damage after recovering IH. 2) To check whether the results obtained in vitro on the recovery of the damage according to the form of manifestation of IH are validated in SAHS patients. 3) To determine if CPAP reduces nighttime blood pressure and arterial stiffness depending on whether or not patients have a non-dipping pattern of blood pressure and depending on the degree of correction of IH. 4) To clarify whether residual nocturnal hypoxemia influences the recovery of oxidative and inflammatory damage in patients. 5) To determine nasal and intestinal microbioma and the effect of CPAP treatment

The study aims to evaluate the effect of non-supine positioning in the treatment of surgical patients with obstructive sleep apnea. The hypothesis is that non-supine positioning will result in a decrease in acute hypoxic events, defined as the number of apneas/hypopneas per hour of sleep.

The obstructive sleep apnoea/hypopnoea syndrome (OSAHS) is a breathing disorder which happens at night and consists of the interruption of airflow for more than five seconds. His current treatment by continuous positive pressure nocturnal machine (CPAP) is not curative and therefore the level of compliance is key to patient improvement. Many patients don´t tolerate CPAP by the numerous side effects involved. The Upper Airway Toning is a compendium of non-invasive techniques that aim to assist tolerance and compliance with the CPAP. These techniques are: oropharyngeal exercises executed actively by the patient for the muscle toning of the upper airways, electrostimulation of the muscles in the floor of the mouth, correction of the tongue position, nasal and bronchial fogging, execution of respiratory gymnastics, therapy myofascial in the oropharyngeal muscles, manual therapy in the cervical column,and massage in the diaphragm. All the techniques together seek for a greater or lesser impact on the upper airways hypotony, the hypotony of the tongue and the soft palate, the jaw retrognathism, the mouth breathing, the vertebrobasilar syndrome, the gastroesophageal reflux, the excessive accumulation of secretions in the upper and lower airways, the obstructive and restrictive respiratory problems, the sleeping posture, the hypertonia of the diaphragm due to the excess effort in trying to overcome the respiratory obstruction. All these disfunctions will make easier for the patient to show side effects in the use of CPAP. There will be a double-blind randomized controlled study with 110 individuals. One group will follow the conventional medical treatment with CPAP and the other group medical treatment plus Upper Airway Toning. After six months, the mean improvement between the two groups will be compared.

Investigators assume that continuous positive airway pressure (CPAP) therapy can reduce the mortality, stroke rate and secondary coronary surgery in CAD with obstructive sleep apnea (OSA) patients after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABA) during postoperative follow-up of 3 years.

The purpose of this study is to determine whether the Optical coherence tomography (OCT) can image the structure and geometry of hollow organs of the upper airway in sleep disorder. The research can identify the obstruction sites that help the select the appropriate treatment for potential surgical candidates.
