Filter by:This pilot study is intended to evaluate the acceptance and performance of the DreamMapper application and the Therapist Assist educational tool in naïve patients with Obstructive Sleep Apnea who have been prescribed Positive Airway Pressure therapy. A total of approximately 60 naïve participants will be recruited.
This study studies the prevalence between obstructive sleep apnea syndrome and sensorineural hearing loss. We recruit patients who have been treated for sudden sensorineural hearing loss in Poitiers' University Hospital between 2010 et 2017, and we detect if they have OSA with a ventilatory polygraphy.
This study compares the titration pressures achieved through two auto-titrating modalities, a new incremental fixed pressure mode versus routine auto-adjusting pressure mode, in CPAP-naïve obstructive sleep apnea patients. The aim of the study is to verify that this new modality achieves a lower titration pressure.
This investigation is a prospective, non-randomized, non-blinded study. This investigation is designed to evaluate the performance, comfort and ease of use of the F&P Toffee mask amongst Obstructive Sleep Apnea (OSA) patients. Up to 45 OSA patients will be recruited from the Pulmonary Disease Specialists Research database.
This investigation is designed to evaluate the performance as well as the patients overall acceptance of the interface.
In this prospective randomized cross-over trial, 3 different titration procedures will be compared: 1. titration of the mandibular advancement device (MAD) in the home setting based on both the physical limits of the patient's mandibular protrusion and the resolution of subjective complaints, as currently often used in routine clinical practice; 2. an overnight titration PSG using the remotely controlled mandibular positioner (RCMP) with stepwise mandibular protrusion until respiratory events are reduced and 3. incremental protrusion of the mandible during DISE using the RCMP until upper airway collapse at all collapsible levels is eliminated. The aim of this study is to prospectively compare the target protrusion, as well as the treatment outcome in terms of treatment efficacy, of the 3 different titration protocols.
The aim of this study was to estimate and compare the value of the preoperative fentanyl test and the short OSAS screening scale to diagnose severe obstructive sleep apnea；and to observe the required amount of hydromorphone and the adverse respiratory events after adenotonsillectomy.
Obstructive sleep apnea (OSA) is characterized by a repeated partial or complete obstruction of the airway that results in a intermittent hypoxia and sleep disturbance. A complex and reciprocal link between obesity and OSA exists. On the one hand, obesity is one of the main risk factors for OSA. On the other hand, OSA seems to promote obesity. The changes in sleep patterns that characterize OSA alter energy metabolism and promote weight gain. In particular, OSA is associated with metabolic disturbances, decreased physical activity and changes in energy expenditure resulting in weight gain. OSA is characterized by resistance to leptin which reduces the feeling of satiety and an increase in ghrelin levels which increases the feeling of hunger. There may be an increase in food intake, but very few studies have looked at this aspect. Our current knowledge is based on simple patient reports of the amount of food consumed per 24 hours. First-line treatment of OSA is based on continuous positive airway pressure (CPAP) but this approach is not curative and weight loss is encouraged. CAPP could facilitate weight loss by restoring sleep quality. Paradoxically, recent studies show weight gain proportional to the duration of use of CPP. Randomized controlled trials offering apneic patients a return to physical activity and hygiene-dietary rules have shown an improvement in OSA after weight loss. A better understanding of the influence of OSA and its treatment on the energy balance through food preferences and olfacto-gustatory sensoriality is an essential prerequisite for personalized nutritional management. In the face of unexpected weight gain under CPP, this type of intervention would be all the more beneficial as OSA and obesity are public health problems representing two independent risk factors for cardiovascular morbidity and mortality with increasing incidence. We hypothesize that the treatment of OSA with CPAP changes food preferences in favour of fatty and sugary high-calorie foods.
Sugammadex or neostigmine are given at the end of the surgery to reverse neuro muscular blocking drugs. This study will evaluate whether reversal of NMBD with sugammadex is associated with faster recovery than neostigmine resulting in faster discharge from the operating room (OR) in obese patients with OSA undergoing bariatric surgery. Half of the patients in the study will receive sugammadex and the other half of the patients will receive neostigmine.
Obstructive sleep apnea (OSA) has been associated with cardiac repolarization abnormalities and implicated in sudden cardiac death. A biologically plausible mechanism by which OSA exerts this lethality is by QT interval prolongation, a known marker of ventricular tachyarrhythmias (VTA) leading to cardiac death. Congenital long QT syndrome (LQTS) is a familial arrhythmogenic disorder characterized by prolonged QT interval on the electrocardiogram and increased propensity for VTA. Preliminary data identify an association of the extent of severity of OSA and progressive prolongation of the corrected QT interval in LQTS.
