Active clinical trials for "Apnea"

This is a research study using caffeine in children who have an obstructive sleep apnea (OSA). OSA means children who stop breathing during their sleep due to obstruction in their airway. The purpose of this study is to determine whether caffeine when given in the vein, will wake children up faster and decrease post-anesthesia airway obstruction, as well as the safety and if the drug agrees with the child compared to a placebo (an inactive or dummy agent).

The purpose of this research study is to determine the effect of chronic nighttime low oxygen saturations on selected body systems (liver) that break down drugs in children with obstructive sleep apnea syndrome (OSAS).

The purpose of this study is to assess whether tonsillectomy and UPPP performed using the study device to treat Obstructive Sleep Apnea (OSA) symptoms in adults is associated with less postoperative pain during the 21-day postoperative recovery period compared to electrocautery dissection.

Sarcoidosis is a multisystemic granulomatous disease that affects individuals worldwide without known pathogenesis, and the role of comorbidities has not been fully assessed in the scientific literature. An increased incidence of Obstructive Sleep Apnea Syndrome (OSAS) has been described in Sarcoidosis although this association has not been explained yet and no data is available about the effect of treatment with Continuous Positive Airway Pressure (CPAP) in Sarcoidosis. Also, patients affected by Sarcoidosis usually experience a state of physical and mental weariness called fatigue and reported in approximately 60-80% sarcoid patients and thought to be a consequence of inflammatory mediators but the high prevalence of OSAS could be a remarkable bias in clinical evaluation because fatigue is also strongly associated with sleep disorders. Thus, there is a real need for assessing not only the real prevalence of OSAS in Sarcoidosis but also the effect of CPAP treatment on fatigue status experienced by sarcoidotic patients.

Airway management is a core clinical skill in anaesthesia. Pre-oxygenation prior to induction of anaesthesia is standard practice to prevent desaturation. Apnoeic oxygenation in adults is effective and prolongs the time to desaturation. The effectiveness of apnoeic oxygenation in the adult is well document, however evidence in the paediatric is lacking. Therefore, the aim of this study was to investigate the effectiveness of apnoeic oxygenation during airway management in children. This was a pilot randomised controlled trial. Patients were randomised to either receive apnoeic oxygenation or standard care during the induction of anaesthesia. The primary outcome was the duration of safe apnoea, defined as a composite of the time to first event, either time for SpO2 to drop to 92% or time to successfully secure the airway, and the lowest SpO2 observed during airway management. Secondary outcomes were number of patients whose SpO2 dropped below 95% and number of patients whose SpO2 dropped below 92%.

This study aims to investigate the influence of a potential leg fluid shift (LFS) in patients with chronic heart failure (CHF) and obstructive sleep apnea (OSA) or central sleep apnea (CSA).

Obstructive Sleep Apnea Syndrome (OSA) is one of the most common chronic diseases and is associated with prognostic cardiovascular and metabolic co-morbidities. OSAS is the recurrence of complete (apnea) or partial (hypopnea) collapse of the upper airway during sleep resulting in sleep fragmentation and chronic intermittent hypoxia (ICH) which are the major determinants of cardiovascular and metabolic complications including type 2 diabetes, obesity and non-alcoholic fatty liver. These comorbidities are associated with a change in intestinal microbial ecology. In most cases, there is a reduction in bacterial genetic diversity and more or less specific signatures of cardiovascular and metabolic diseases, making it possible to envisage personalized and innovative therapeutic treatments. In animals exposed to intermittent hypoxia, there is local hypoxia that increases intestinal permeability, produces a reduction in microbiota diversity and favors microbial species that are at the origin of pro-inflammatory factors. Continuous Positive Airway Pressure (CPAP) is the standard treatment for OSA. Its effect on the intestinal microbiota has not yet been evaluated.

The DO OAM study is a mono-center, interventional, prospective study carried out in CH VALENCE. It will estimate the prevalence of dental movements in patients treated by oral Appliance for Sleep Apnea syndrome. The investigators will used fingerprinting technique by taking multiple photographs of the teeth that allow for the three-dimensional reconstruction of the teeth this study will provide a better understanding of dental movement caused by oral appliance

The therapeutic management of Obstructive Sleep Apnoea Syndrome in children remains a debated subject, only otorhinolaryngology surgery (adenoidectomy) has been studied on a large scale. Pathophysiologically, increased pharyngeal collapsibility is a major endotype of the disease and the investigators have shown that this surgery can improve pharyngeal compliance. The development of approaches to treat pharyngeal hypotonia by maxillofacial rehabilitation supports the treatment of this endotype. A study in adults showed a benefit from playing the didgeridoo, a wind instrument, for 3 months, without pathophysiological explanation. The investigators hypothesise that playing this instrument improves pharyngeal compliance (re-education effect) in a similar way to the effect observed after otorhinolaryngology surgery. This proof-of-concept study aims to demonstrate the effect of didgeridoo in children without syndromic pathology with a formal otorhinolaryngology surgical indication resulting from tonsillar hypertrophy (Brodsky grades III and IV) and symptomatology suggestive of Obstructive Sleep Apnoea Syndrome (Pediatric Sleep Questionnaire score ≥ 0.33). The investigators will take advantage of the long delay in performing the adenoidectomy (~6 months) in their university hospital to evaluate, before the scheduled surgery, the effect of the didgeridoo used for three months.

The main objective of this study is to evaluate the accuracy of the ANNE Sleep system for the diagnosis of obstructive sleep apnea (OSA) in adults
