Active clinical trials for "Apnea"

Adaptive Servo-Ventilation (ASV) treatment is routinely prescribed in France. In order to be reimbursed according to the French Social Security rules, the patient treated with an ASV needs to be examined each year. In this observational transversal single-visit study, the investigators aim to describe the clinical characteristics of patients treated with ASV and the associated device settings.

The study will evaluate the post-operative morphine-sparing effect, pain reduction, and side effects of a continuous ketamine infusion after tonsillectomy in pediatric patients.

This will be a prospective study in subjects with Obstructive Sleep Apnea (OSA) to characterize the clinical performance during a single night of therapy with a FRESCA mask compared with a single night of therapy with their existing nasal Continuous Positive Airway Pressure (CPAP) mask.

Obstructive sleep apnea (OSA) is a common disorder characterized by recurrent collapse of the upper airway during sleep. OSA patients have a small upper airway that is kept patent during wakefulness by a compensatory increase in upper airway (UA) dilator muscle (e.g. genioglossus) activity. At sleep onset this compensation is reduced or lost, resulting in upper airway narrowing or collapse. Previous studies of upper airway muscle training showed variable results on OSA, but so far there has not been any practical, long-term, systematic upper airway muscle training developed or studied as the treatment of OSA. In theory, strengthening the upper airway muscle with exercise training in theory helps maintain a patent airway during sleep. Therefore, investigators aim to test the hypothesis: 1) UA muscle training can improve sleep apnea in some patients with OSA, including those already receiving treatment with PAP or oral appliance therapy. 2) Muscle training is a viable therapy for a definable subset of OSA patients. Investigators hypothesize that patients with OSA who have mild or moderately compromised upper airway anatomy will benefit the most. 3)There will be a positive association between the changes in muscle function and improvement in OSA severity.

The purpose of this study is to determine whether Continuous Positive Airways Pressure (CPAP) improves quality of life, cardiovascular (blood pressure) and metabolic profile (glucose and lipid metabolism) in females with moderate-to-severe Obstructive Sleep Apnea (OSA).

Rationale: Almost all the information the investigators have about the effect of continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA) comes from randomized clinical trials including only middle-aged patients. Little is know, however, about the effect of CPAP in elderly people with OSA. Objective: To assess the effect of CPAP treatment in elderly patients with severe OSA on clinical, quality-of-life and neurocognitive spheres. Methods and Measurements: Open-label, randomized, multicenter clinical trial of parallel groups with blinded end-point design conducted in 12 Spanish teaching hospitals on a consecutive clinical cohort of elderly (≥ 70 years) patients with confirmed severe OSA (IAH≥ 30) receiving CPAP or no therapy while maintaining their usual control for three months. CPAP titration was performed by an auto CPAP device. A good adherence was set as at least 4 hours/day of CPAP use. Primary endpoint was the measurement of quality of life by the Quebec Sleep questionnaire, which includes diurnal and nocturnal symptoms, hypersomnolence, and social and emotional dimensions. Secondary endpoints include different sleep-related symptoms, presence of anxiety or depression, office blood pressure figures and some neurocognitive tests. Patients were invited to a clinical visit on three occasions to quantify the adherence to CPAP. Intention-to-treat analysis was performed.

The purpose of this study is to determine the effectiveness and feasibility of upper airway muscle physical therapy utilizing negative airway pressure (NAP) breathing training in patients with Obstructive Sleep Apnea Syndrome (OSAS) in reducing both signs (apnea hypopnea index) and symptoms (i.e., daytime sleepiness).The key to the proposed therapy is the use of Negative Air Pressure when awake so that the increased reflex phasic drive to the muscles will result in muscle conditioning. Interestingly, other studies have indicated that upper airway muscle training may be useful in treating OSAS, but these studies used techniques that were not scientifically designed{Puhan, 2006 8195 /id} or used a technique (electrical stimulation) that was not well tolerated.{Lequeux, 2005 7514 /id}

Incomplete recovery of neuromuscular function after surgery can lead to respiratory complications. Patients with obstructive sleep apnea (OSA) are prone to respiratory complications after surgery. Neostigmin and sugammadex are used for neuromuscular reversal. The aim of this study was to compare sugammadex and neostigmin regarding efficacy, incidence of respiratory complications and cost in patients undergoing surgery for OSA

This is a proof of concept study to determine the safety and efficacy of dronabinol for the treatment of obstructive sleep apnea syndrome (OSA).

The main objective is to evaluate an osteopathic compression of pterygopalatine node in healthy subjects and patients suffering from obstructive apnea syndrome (OSA).
