Active clinical trials for "Sleep Apnea, Obstructive"

The purpose of this study is to investigate the effect of treatment with a steroid and antibiotic on the size of the tonsils and symptoms of children with OSAS.

The purpose of this study is to determine if an Autoadjusting CPAP machine is better than the regular CPAP machine in treatment of Obstructive Sleep Apnea in the postoperative setting.

This study will examine whether treatment of inferior turbinates in patients with continued symptoms of obstructive sleep apnea, sleep related breathing disorder, snoring, disturbed sleeping, open mouth breathing, and upper airway resistance syndrome after tonsillectomy and adenoidectomy will improve these symptoms and should be included in the treatment paradigm for treatment of sleep related breathing disorders in infants, children, and adolescents.

This study will use a modified version of a positive airway pressure device to supply air to the participant, while undergoing supervised polysomnography. Positive airway pressures are typically applied to many patients with hypoventilation, in this study these pressures will be titrated by a qualified sleep technician. During the night these pressures will be altered to optimise comfort.

That the level of humidification delivered to patients during CPAP treatment will alter the subjects mucociliary clearance rate and related mucus properties.

The purpose of this study is to determine whether modafinil use in patients with obstructive sleep apnea will improve postoperative delayed emergence after general anesthesia.

This investigation is designed to evaluate the performance, comfort and ease of use of the Simplus and Eson masks amongst NIV patients who are currently on Bi-level therapy

Laparoscopic Adjustable Gastric Banding (LAGB) is a gold standard in the surgical treatment of morbid obesity. We hypothesize that the addition of truncal vagotomy (cutting of nerves to the stomach) will produce greater weight loss and better reduction of co-morbidities (diseases caused by or aggravated by morbid obesity) than LAGB alone. 25 patients will be enrolled and outcomes compared to LAGB historical controls over a post-operative period of 24 months.

Obstructive Sleep Apnea Syndrome (OSAS) in children is a significant public health problem whose clinical diagnosis is not specific. The recording of sleep and breathing (polysomnography, PSG) is the reference exam. PSG consists in installing on the child's body electrodes necessary to determine the sleep stages and sensors used to determine the presence of respiratory events during sleep. At-home PSG, compared to hospital PSG, improves sleep quality. PSG is yet an anxious exam due to the multitude of electrodes and sensors. Ventilatory polygraphy (PG) consists of installing only respiratory detectors. The objective of this study is to demonstrate that at-home PG has the same diagnostic value as at-home PSG.

Currently, mandibular advancement devices (MAD) are recommended by the American Academy of Sleep Medicine (AASM) as the first treatment a line in cases of mild and moderate OSAS in patients without severe cardiovascular comorbidity and in severe OSAS when treatment with CPAP fails or is rejected. Although oral appliances (OD) have less impact on AHI reduction, both treatments have been shown to have a similar impact on clinical outcomes, including symptomatology and cardiovascular outcomes. In addition, MAD is a treatment that is better tolerated by patients, which results in greater compliance on their part, and therefore a similar efficacy in clinical practice. Its mechanism of action consists of maintaining the patency of the upper airway, preventing collapse. They act by correcting the anatomical imbalance of patients with OSAS, specifically stabilizing and increasing the space of the velopharyngeal airways, reducing their collapsibility. However, the effectiveness of the treatment of this pathology using MAD is limited by the inter-individual preference of the results of the treatment and the lack of information in the correct selection of the appropriate patients. In fact, oral appliances are an effective treatment for 60-70% of patients. Therefore, the precise selection of patients is essential to optimize the results of MAD treatment and thus avoid the necessary costs. This justifies the need to identify phenotypes likely to predict response to MAD treatment.
