Obstructive sleep apnea (OSA) is a sleep-related respiratory dysfunction. The prevalence of OSA is increasing with the increasing rates of obesity and elderly population worldwide. Perioperative anesthesia management should be adjusted to improve patient safety in patients with OSA. In OSA patients, positive pressure ventilation support may be required in the preoperative period, various ventilation strategies may be required in the intraoperative period, different pharmacologic agents may need to be avoided, and intensive care unit follow-up or noninvasive ventilation support may be required in the postoperative period. However, it is reported that a significant percentage of OSA patients remain undiagnosed. ASA (American Society of Anesthesiologists) has reported the criteria that should be questioned in order to determine the risk of patients in terms of OSA and to initiate the diagnostic process in risky patients and to make appropriate anesthesiologic arrangements in the perioperative period. In addition, the STOP-BANG assessment scale, which is widely used all over the world in OSA risk assessment, is also used in OSA risk assessment. It is thought that dental caries and extraction needs may be higher in OSA patients, especially since open-mouth sleeping accompanies the situation. In this respect, it is also important for patients to be diagnosed with OSA as it may prevent dental damage due to open-mouth sleeping in the future. Identifying patients at risk for OSA and directing them to the diagnostic process is very important for patient safety. Within the scope of the study, the criteria recommended by ASA and STOP-BANG score will be evaluated and recorded. Risk stratification in terms of STOP-BANG questionnaire and ASA criteria will be done separately for each patient and for each classification method. Patients at high risk will be consulted to the relevant medical department in the preoperative period for further investigation and treatment. In addition, it is aimed to correlate the risk levels determined in the study with postoperative respiratory complications and recovery time.

NCT07292922
This pilot study explores the feasibility, acceptability, and preliminary effectiveness of Digital-supported Orofacial Myofunctional Therapy (d-MFT), an innovative program combining facial recognition technology with evidence-based orofacial exercises for individuals with mild to moderate obstructive sleep apnoea (OSA). The d-MFT program aims to strengthen oropharyngeal muscles, improve airway function, and reduce OSA severity. Participants receiving 3-month d-MFT (n=30) are expected to demonstrate greater improvements in OSA severity, sleep-related symptoms, and quality of life compared to those in the waitlist control group (n=30). Feasibility and acceptability will be evaluated through outcome-based questionnaires and semi-structured interviews to explore participants' experiences, satisfaction, and perceived barriers to adherence.
NCT07469280
The purpose of this study is to evaluate the feasibility and effects of a 12-week high-intensity progressive Inspiratory Muscle Training (IMT) program in individuals with Class III obesity (BMI ≥ 40 kg/m²) and obstructive sleep apnea (OSA). Using a single-case experimental design (SCED) with multiple baselines, the study will investigate whether this respiratory intervention can reduce the severity of sleep apnea, as measured by the Apnea-Hypopnea Index (AHI), and improve inspiratory muscle strength and sleep quality. Participants will perform daily training sessions using a resistive loading device (POWERbreathe), with intensity progressing from 40% to 90% of their maximum inspiratory pressure.
NCT06043830
Patients with chronic pain who use opioids appear to be at increased risk for breathing issues during sleep, termed sleep disordered breathing (SDB). Treatment of SDB often consists of use of a device during sleep that provides continuous positive airway pressure (CPAP) via a mask interface. However, this device is not effective or tolerated in all individuals. The goal of this study is to examine whether a medication called acetazolamide can improve SDB, as an alternative to CPAP treatment. The investigators will measure the improvement in SDB, as well as any change in symptoms, during a 1 week treatment with acetazolamide compared with 1 week of placebo (sugar pill). This study will help to provide data for longer term studies of treatment for SDB in patients who use opioids.
NCT07225686
This Phase 3 clinical trial is designed to evaluate the efficacy and safety of maridebart cafraglutide compared to placebo over a 52-week period in adults with obstructive sleep apnea (OSA) who are receiving positive airway pressure (PAP) therapy and are living with overweight or obesity.
NCT07301125
The purpose of this study is to explore a new way to examine the function of the muscles using a technique called high-resolution manometry. The study will enroll 30 adults with OSA, all of whom will use the myofunctional therapy (MFT) devices for 3 months. High-resolution manometry will be used to measure the amount of pressure generated by the muscles of the throat when drinking water or breathing air, both with and without the MFT devices, and before and after the MFT intervention. If successful, this method can help us understand why sleep improves after MFT.
NCT07446634
This study looks at how jaw surgery called maxillomandibular advancement with counterclockwise rotation affects breathing during sleep in people with moderate to severe obstructive sleep apnea who cannot tolerate standard treatments such as Continous Positive Airway pressure treatment. The participants are followed over time to see whether the surgery improves sleep apnea symptoms, daytime sleepiness, and airway size, and whether these improvements last. Advanced three-dimensional imaging and airflow analysis are used to better understand how the surgery changes the airway and breathing. The goal is to evaluate the long-term effectiveness and safety of this surgical treatment.

Atrial fibrillation (AF) is one of the most common clinical arrhythmias. Catheter ablation is an effective therapeutic strategy; however, recurrence rates remain substantial, ranging from 20% to 45%. Previous studies have established a strong association between obstructive sleep apnea (OSA) and the risk of AF recurrence following ablation. While continuous positive airway pressure (CPAP) is the standard intervention for OSA, and some observational studies suggest it may reduce post-ablation recurrence in patients with comorbid OSA, small randomized controlled trials have failed to confirm a clear benefit, potentially due to poor adherence. This study aims to evaluate the clinical benefit of post-ablation CPAP therapy in AF patients with comorbid OSA. Participants will: * Be randomly assigned to either the CPAP group or the usual care group. * If in the CPAP group, use a CPAP device for 12 months. * Wear an ambulatory ECG recorder at least once a week to monitor their heart rhythm. * Complete follow-up checkups either at the clinic or over the phone at 1, 3, 6, and 12 months after their procedure.

NCT07195253
Obstructive Sleep Apnea (OSA) is characterised by repetitive collapse of the upper airway during sleep, inducing breathing disturbances that can result in oxygen desaturation and frequent arousals. In children, OSA can have long-term consequences on the development and on the cardiovascular system. Down Syndrome (DS) is a genetic disorder associated with intellectual disability and many comorbidities. The prevalence of OSA is particularly high in patients with DS, from infancy. In a recent study by Fauroux et al. (2024), OSA was diagnosed in 97% infants and early diagnosis and intervention from the age of 6 months was associated with better neurocognitive outcome at 3 years old. However, polysomnography (PSG - the gold standard method for diagnosing OSA) is poorly accessible, highlighting the need to develop new strategies to prevent and to screen OSA early in infancy. OSA can be linked to some orofacial abnormalities presented by patients with DS. Indeed, orofacial functions and structures ca play a crucial role in OSA. For example, nose breathing allows the tongue to act as a stimulator of the transverse maxillary growth during childhood, allowing the upper airway to develop properly. The primary objective of the present study is to explore the relationships between oro-myo-facial functions, more specifically non-nutritive sucking, and the severity of OSA in 6 months old infants with DS. The main hypothesis is that OSA severity (estimated by the obstructive apnea hypopnea index on PSG) will be negatively correlated to non-nutritive sucking performance. Data from this study could help developing easily accessible protocols for OSA screening based on simple sucking recording. Some interventions could also be tested to prevent OSA from the beginning of life, like an innovative pacifier recently developed by a French start-up to stimulate nose breathing and to promote correct positioning of the tongue.

NCT07380321
This is a prospective observational study evaluating perioperative diaphragmatic function by ultrasonography in children aged 1-12 years undergoing elective surgery under general anesthesia. Participants will be classified preoperatively based on the parent-completed Pediatric Sleep Questionnaire (PSQ). Children with suspected obstructive sleep apnea syndrome who are scheduled for adenotonsillectomy will form the study group, while children without clinical findings suggestive of obstructive sleep apnea who are scheduled for elective non-airway-related otolaryngologic surgeries will serve as controls. Diaphragm ultrasound assessments will be performed before and after surgery in the supine position during spontaneous breathing. Measurements will include diaphragmatic thickness at end-inspiration and end-expiration, diaphragmatic thickening fraction, and diaphragmatic excursion during quiet and deep breathing. The primary objective is to compare diaphragmatic excursion and thickening fraction between groups. Secondary objectives include evaluating the association between perioperative respiratory parameters, postoperative recovery, and diaphragm ultrasound measures.
