Filter by:The links between obstructive sleep apnea syndrome (OSAS) and type 1 diabetes (T1D) are poorly studied. This study proposes to evaluate the severity of cardiovascular autonomic neuropathy (CAN) related to T1D in case of associated OSAS. This issue has significant diagnostic and therapeutic implications because of the increased cardiovascular risk in case of confirmed CAN in T1D patients.
Obstructive sleep apnea (OSA) has been found to be very common in stroke patients. Obstructive sleep apnea has been found to impede stroke rehabilitation and recovery. However, currently, there are few treatment options for OSA in stroke patients. Continuous positive airway pressure (CPAP) is the current therapy commonly used for OSA in the general population, however stroke patients are not highly compliant with this device. Therefore, we have decided to propose a more feasible alternative to treating obstructive sleep apnea through positional therapy. Positional therapy involves using a device to prevent patients from sleeping on their backs, since this position has been found to exacerbate obstructive sleep apnea. Therefore, we hypothesize that stroke patients who use the positional therapy belt will experience improvements in the severity of OSA.
This study compares the effect of Montelukast vs Placebo on Flow Mediated Dilatation of the Brachial Artery (FMD) in patients with obstructive sleep apnea syndrome.
Continuous positive airway pressure (CPAP) treatment improves sleepiness, depression and social activities in patients with obstructive sleep apnea (OSA). This evolution can be captured from changes in phone usage habits coupled with a mobile-based services. The aim of this study is to assess the impact of CPAP treatment on phone usage habits in OSA patients.
The investigators have previously shown that 1 week of 10mg Melatonin improves sleep consolidation in untreated obstructive sleep apnea (OSA) patients. This study aims to extend on those findings to determine if longer treatment of Melatonin improves other outcomes in untreated OSA patients.
Patients undergoing suspension laryngoscopy under general anaesthesia have oxygen delivered to their lungs through different methods. Inserting a tube in the trachea is the best means for oxygen delivery. However, it does not allow for optimal visibility of the operated area. Other techniques can be used but have disadvantages with some being associated with serious complications. No consensus exists regarding the best airway management technique for this intervention. The aim of the study is to investigate a new device that delivers oxygen at very high flow through a nasal cannula in patients undergoing suspension laryngoscopy under general anaesthesia. This technique allows the surgeon to have a perfect visualisation of the laryngeal structures while allowing the delivery of oxygen for the lungs. After informed consent, adult patients undergoing suspension laryngoscopy under general anaesthesia in two French hospitals will receive high flow oxygen throughout the procedure. At the end of surgery or, whenever applicable, at the time of technique failure (with a decrease in blood oxygen saturation to less than 92%), blood will be drawn for analysis. All patients will have a thin security catheter inserted in their trachea (the currently used technique in both participating hospitals), allowing for rescue high frequency ventilation if ever the study technique fails. The safety of the device will also be assessed by analysing the blood samples for signs of carbon dioxide accumulation and by collecting any intra or post-operative complications. If the device shows to be effective at maintaining blood oxygenation without significant associated risks, it could be used for other surgical situations where airway management is expected to be difficult.
The aim of this study is to investigate the effects of morphine (a drug commonly used for the treatment of moderate to severe pain, particularly following surgery) on the number of pauses in breathing in patients with moderate obstructive sleep apnoea (OSA). Morphine has been shown to reduce upper airway muscle tone and can also cause shallow breathing, which can affect breathing function in patients with sleep apnoea. However, to date these effects have not been proven in clinical trials. Although, caution is advised when prescribing morphine to patients with sleep apnoea, there is currently no strong evidence that morphine makes sleep apnoea worse. Only one randomised controlled trial (considered the gold standard in medical research) has shown no worsening of symptoms for patients with sleep apnoea. The effect of morphine on patients with sleep apnoea will be assessed in a safe, controlled, hospital environment. Information from the study will help inform doctors about the safety of giving morphine to patients with sleep apnoea in urgent situations, for example after surgery. The results of this study will enable clinicians to make better decisions when prescribing this drug to patients with OSA in the future.
The aim of this study is to substantially reduce overall postoperative morbidity and mortality associated with obstructive sleep apnea.
To investigate whether nHFT is an effective treatment for patients with Chronic Heart Failure (CHF) and central sleep apnea (CSA). This study is a prospective one armed uncontrolled intervention pilot study investigating 4 weeks of nHFT at home in 10 patients with CHF and CSA.
Myofunctional therapy has been shown to be effectively reduce symptoms of paediatric sleep apnea. As the effectiveness of reeducation relies on parental involvement and child's compliance, the investigator's research question was to evaluate two methods of myofunctional therapy (daily oral exercices versus a flexible oral appliance, both in combination with nasal hygiene), compared to nasal hygiene alone (control group).
