Filter by:The purpose of this study is to compare the use of short acting opioids (fentanyl/hydromorphone) with long acting opioids (methadone) for pain control following tonsillectomy surgery.
It was aimed to investigate the effect of expiratory muscle strength training (EMST) applied at different intensities on systemic inflammation and oxidative stress in patients with moderate obstructive sleep apnea syndrome (OSAS). In the study, 32 male patients diagnosed with moderate OSAS will be included in the study. Participants will then be divided into 2 groups by block randomization. In the three-blind planned study; the first group will receive high-intensity %60 maximum expiratory pressure (MEP) EMST training, and the second group will be given low-intensity 30% of MEP, EMST training for 12 weeks. Disease-related symptoms, disease severity apnea-hypopnea index (AHI), oxidative stress index (OSI) and systemic inflammation level, exercise capacity, respiratory muscle strength, sleep quality, daytime sleepiness, and fatigue severity will be evaluated before and after the study.
multi-center, randomized, double-blind, placebo-controlled, dose-finding, 4-arm, parallel assignment study to evaluate the efficacy of three different doses of sulthiame (STM) compared to placebo on sleep apnea activity in adult patients with obstructive sleep apnea.
A prospective, randomised, blinded pilot study comparing the Sunrise solution and overnight polygraphy for the diagnosis of OSA in adult patients. Patients under investigation for OSA will use both devices simultaneously for a single overnight sleep study. They will be randomised to receive their treatment decision based on either the Sunrise solution or polygraphy. A retrospective check of their diagnosis will be done.
The objective of this study is to assess the efficacy of the Orthoapnea NOA® mandibular advancement device and describe the percentage of advancement (%) needed to reach efficacy, and to retrospectively compare with other MAD designs in the management of obstructive sleep apnea. Additionally, to describe patient compliance and adherence to the therapy with the Orthoapnea NOA® device, and to assess the incidence and prevalence of signs, symptoms, and diagnosis of temporomandibular disorders (TMD) associated to the use of the Orthoapnea NOA® mandibular advancement device.
The prevalence of Obstructive Sleep Apnea (OSA) is high in individuals after a stroke. There are few studies evaluating the effects of inspiratory muscle training (IMT) in individuals with OSA and the findings regarding the possible effect on Apneia/Hipopneia Index (AHI) reduction are still controversial. This study will test the hypothesis that training of the inspiratory muscles is effective in improving severity of OSA, sleep quality and daytime sleepiness in individuals after stroke participating in a rehabilitation program. Methods: For this prospective, sigle blinded, randomized clinical trial, people after stroke will be randomly allocated into either experimental or control groups. The experimental group will undertake training of the inspiratory muscles with the PowerBreath Medic Plus regulated at 75% of the subjects' maximal inspiratory pressure (MIP) values, five times/week over five weeks 5 sets of 5 repetitions with 1 set increasing each week. Both groups will participate in the rehabilitation program and will receive the same dose of physiotherapy, speech therapy and aerobic exercise sessions. At baseline and post intervention after the cessation of the interventions, researchers blinded to group allocations will collect all outcome measures. Study outcomes: Primary outcome will be OSA severity measured using the Apnea/Hypopnea Index (AHI). Secondary outcomes will include inspiratory endurance and pressure, functional independence, sleep quality and daytime sleepiness
The need for multiple night testing is well recognized in sleep medicine because of a considerable and relevant night-to-night variability. In a study with multiple recordings using WatchPAT®, the OSA severity of 24% of patients was misclassified when using one night compared to the average of three nights. On average, pAHI varied by 57% from night-to-night. The variability of pAHI could partially be explained by the variability of time spent in the supine position with more time supine leading to a higher pAHI (Tschopp et al 2021). Smith (2007) suggested that the AHI should be indicated with a confidence interval to indicate the uncertainty regarding its true value. The Minimal Detectable Difference (MDD) is of special interest in sleep medicine, especially when assessing treatment effects. MDD was found to be 12.8/h and the standard error of measurement was 4.6/h for 4 nights of polysomnography (Aarab et al. 2008). For WatchPAT®, measuring two and three nights showed a small reduction in MDD from 19.1/h to 18.0/h (Tschopp et al. 2021, in press). Only one study using pulse oximetry assessed the night-to-night variability over 14 days (Stöberl A. et al 2017). The study confirmed the enormous variability and focused mainly on its impact on OSA severity. While the night-to-night variability has been extensively studied for polysomnography, respiratory polygraphy, and WatchPAT®, little is known about the optimal number of nights to be recorded. There is convincing evidence from the literature, that the recording of multiple nights is the only way to assess the severity of the patient's disease with clinically reasonable accuracy. Moreover, the MDD with only one night's recording is astonishingly high. The question is how many nights should be recorded to achieve acceptable diagnostic accuracy. The precision of the OSA measurement depends on the clinical situation. For example, to diagnose severe OSA, a higher variability might be acceptable without influencing the treatment decision. However, when comparing treatment effects, the MDD should be as small as possible. The recording of multiple nights might be cumbersome for patients (e.g. with polysomnography or respiratory polygraphy) as well as costly. These factors have to be taken into consideration for the clinically feasible number of recordings. Sleepiz One Connect offers the unique opportunity for a contactless recording of breathing combined with conventional pulse oximetry and is a minimally invasive diagnostic tool that allows measurements over several nights. Studies with multiple night recordings will offer a basis for diagnostic recommendations in future guidelines. The study aims to investigate the variability of obstructive sleep apnea at-home sleep apnea testing. By investigating the variability, we want to quantify the improvement in diagnostic accuracy by additional measurements. The hypothesis is that additional recordings offer a significant improvement in diagnostic accuracy by reducing the variability. The reduction in variability will diminish with each additional recording.
A two-year study design is formulated. The overall aim of this study is to examine the effectiveness of the care model combing smartphone application on improve obstructive apnea in obesity adults.
The aim of the study is to find, using validated and efficient tools, a laryngopharyngeal reflux in patients receiving polysomnography for suspected obstructive sleep apnea syndrome. It is proposed to carry out simultaneously, at the Sleep Center of the Polyclinique of Poitiers (CSPP), a polysomnography, a 24-hour Restech pharyngeal pH-metry (day and night), a Peptest (in the evening and in the morning of the polysomnography), with the RSS-12 questionnaire and the RSA score.
The SEED study is designed to assess the safety and efficacy for Obstructive Sleep Apnea (OSA) of 3 escalating dose combinations of atomoxetine with AD313 compared to baseline and to atomoxetine alone.
