Obstructive Sleep ApneaExcessive SleepinessThis trial is a randomized, double-blind, placebo-controlled, crossover study to evaluate the effect of JZP-110 on driving performance in subjects with excessive sleepiness due to obstructive sleep apnea.
Effect of CPAP Treatment in Elderly: Randomized Clinical Trial
Sleep ApneaObstructiveRationale: 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.
Upper Airway Physical Therapy for the Treatment of Obstructive Sleep Apnea
Obstructive Sleep Apnea SyndromeThe 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}
Sleep Disordered Breathing, Obesity and Pregnancy Study (SOAP)
ObesePregnancy1 moreThe purpose of this study is to better understand how sleep apnea, a common sleep disorder in which a person has one or more pauses in breathing or shallow breaths while sleeping, may affect pregnancy and to determine the effect of Continuous Positive Airway Pressure (CPAP), a treatment that uses mild air pressure to keep the airways open during sleep, for pregnant women with sleep apnea.
Semi-up Right Position Study
Obstructive Sleep ApneaOur main objective is to perform an explanatory, first stage proof of concept, randomized controlled trial to determine whether a semi-upright patient position versus a supine position while asleep in the postoperative period helps decrease the worsening of AHI in patients diagnosed with OSA and compare this to usual care (i.e. supine patient positioning while asleep). The investigators will evaluate whether a semi-upright position reduces: worsening of AHI (as measured with a portable PSG) on the second postoperative night (POD2); oxygen desaturation index (using a portable oxygen saturation monitor, oxygen desaturation defined as >4% change below baseline lasting for 10 seconds); REM sleep related change in AHI at baseline and POD2.; major and minor perioperative complications on postoperative day POD1, POD2, at discharge and POD 30.; length of hospital stay and readmission within 30 days; and patient satisfaction score on POD30
Sugammadex Compared With Neostigmin/Atropin for Neuromuscular Block Reversal in Patients With Obstructive...
Obstructive Sleep ApneaIncomplete 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
Nasal Tramazoline and Dexamethazone in Obstructive Sleep Apnea (OSA) Patients Tramazoline and
Obstructive Sleep Apnea SyndromeNasal resistance presents considerable variations during night[8]. Additionally, Oral and oro-nasal breathing epochs exhibit strong correlation with the number of apnoea/hypopnoeas [7].The hypothesis that the present study aims to test is whether the pharmacological prevention of increased nasal resistance during night could alter breathing route pattern and lead to a decrease in the number of apnoea/hypopnoeas in OSA patients with normal nasal resistance.
Bilevel Versus Servoventilation in Complex Sleep Apnea
Complex Sleep ApneaCPAP Induced Central Sleep ApneaRandomized trial to evaluate the performance of Bilevel vs. Servoventilation in patients with complex sleep apnea during continuous positive airway pressure (CPAP) treatment.
The Effects of Treating Obese and Lean Patients With Sleep Apnea
Sleep ApneaObesityThe investigators' overall goal is to compare the effect of CPAP treatment on intermediate cardiovascular risk measures in obese versus lean patients with obstructive sleep apnea (OSA). The overall hypothesis is that, adjusting for OSA severity and obtaining normative data from non-OSA subjects with comparable amounts of visceral adiposity, the two OSA groups will have comparable improvements in daytime sleepiness, but that the cardiovascular and metabolic improvements following CPAP therapy will be decreased in OSA patients with increased visceral adipose tissue. The investigators anticipate that, although there will be a greater absolute change in markers of sympathetic activity, inflammation and oxidative stress in obese compared to lean OSA patients following CPAP treatment, the levels will still be abnormally high in the obese patients resulting in the decreased improvements in insulin resistance, arterial blood pressure, and vascular health in obese versus lean OSA patients.
Comparison of Nasal Positive End Expiratory Pressure Valve to Dental Device as an Alternative Treatment...
Obstructive Sleep ApneaAdverse EffectsDetermine the clinical efficacy in terms of Apnea Hypopnea Index (AHI), excessive daytime sleepiness (EDS), nocturnal oxygenation of a nasal Positive end-expiratory pressure (PEEP) valve "Provent" in obstructive sleep apnea. The hypothesis is the efficacy will be better than dental device.
