Active clinical trials for "Sleep Apnea Syndromes"

Continuous positive airway pressure (CPAP) is the first-line treatment for sleep apnoea/hypopnoea syndrome (OSA). The aim of this study is to know the results in adherence to CPAP and health related outcomes in patients with OSA through a comprehensive and multidisciplinary program based on stratification and individualized care plans, including the motivational interview. Methods: A multicenter randomized controlled trial (RCT) is designed. The control group will follow the usual treatment, while the intervention group (PIMA) will follow the treatment according to the stratification label based on a comprehensive assessment. This label determines a personalized treatment plan for each patient, which includes different channels (home, telephone, care center) and the use of the motivational interview in each of the interventions with the patient. The main outcome was adherence. Secondary outcomes were quality of life, emotional state, activities, social relationships, perceived competence and motivation.

Assessment of the clinical efficacy and adverse effects of multimodal analgesic regimen consisting of nalbuphine combined with ketorolac using IV continuous infusion silicon device (Accufuser) for postoperative analgesia following multilevel OSA surgeries

Mandibular Advancement Devices (MADs) are now a reliable alternative to continuous positive airway pressure (CPAP) treatments for Obstructive Sleep Apnea (OSA) . Despite good tolerance and efficacy, there are still barriers limiting the widespread use of MAD and its acceptance in OSA routine clinical practice. Various MAD designs currently exist and constantly emerge on the market without clear evidence regarding the best technical choice and the cost-effectiveness compromise. Although these MAD has been tested in term of efficacy, no study has tested the difference between MADs in term of efficacy, tolerance and patient satisfaction. The aim of this clinical trial is to compare the effectiveness of two MADs - custom-made titratable MAD (NarvalTM) and customizable titratable MAD (TALITM), over a 3-month period, in patients with obstructive sleep apnea (OSA).

This study intends to assess the effect of nasal airway stent (Nasten®) as a treatment modality in patients with sleep-disordered breathing (SDB) including snoring and/or obstructive sleep apnea (OSA). Nastent®, a distally perforated soft silicon nasal tube, is a mechanical splint against collapse of the upper airway at multiple levels. Nastent® might be able to prevent the vibrations caused by fluttering of various parts of the upper airway which leads to snoring. Furthermore, it also potentially secures a patent airway throughout the night securing airflow.

The aim of this randomized controlled study is to investigate the effect of continues positive airway pressure (CPAP) treatment in patients with dilated cardiomyopathy (DCM) and concomitant obstructive sleep apnea (OSA). The primary endpoint is left ventricular function measured by magnetic resonance (improvement of at least 4%) after six months treatment with CPAP. The secondary endpoints include diastolic dysfunction, cardiovascular biomarkers and quality of life.

A single center, prospective study to assess the efficacy of high flow nasal cannula (HFNC) in improving obstructive sleep apnea (OSA) parameters in patients with reduced tolerance to continuous positive airway pressure (CPAP) treatment.

Patients with obstructive sleep apnea (OSA) are less physically active than healthy controls. First choice of treatment for OSA is continuous positive airway pressure (CPAP) therapy with an improvement in oxygen saturation and sleep. No improvement on physical activity has been shown. The current study would randomize patients in a standard care group (CPAP) and an intervention group (CPAP + telecoaching). Telecoaching will be performed for 3 months, with physical activity assessment before, after 3 months and 12 years.

Demand for Total Knee Arthroplasty (TKA) and Total Hip Arthroplasty (THA) is increasing steadily and is projected to continue trending upwards in the coming years. Concomitant with that trend is the increase in prevalence of obesity. Obesity serves as a common risk factor for osteoarthritis, obstructive sleep apnea and medical complications. Obstructive Sleep Apnea (OSA) is defined as episodes of obstructive apneas and hypopneas during sleep, with daytime somnolence. It occurs commonly in obese, middle age and elderly men and has an estimated prevalence of 5% - 9%. Pre-operative screening for elective surgical procedures is a critical component of a successful surgical outcome. Patients with medical comorbidities ideally will undergo medical treatment or optimization to minimize the risk peri-operatively and post-operatively. Obstructive sleep apnea has been shown in numerous studies to be a risk factor for cardiopulmonary complications following surgery. The contributing factors include alterations in REM sleep post-operatively and opioid induced respiratory suppression post-operatively. The STOP-BANG patient questionnaire is a validated patient survey that uses both objective and subjective data to screen patients for their risk of OSA. The sensitivity of the STOP-BANG questionnaire for moderate-to-severe OSA has been estimated as high as 97.74%. Authors have also shown that higher STOP-BANG scores are independently associated with increased risk for post-operative complication. Other authors have utilized similar pre-operative questionnaires to screen for occult pulmonary disease in patients scheduled for elective joint arthroplasty. They found a slightly increased incidence of OSA in this population as compared with the national average, over 50% of which were previously undiagnosed. The American Society of Anesthesiologists task force on perioperative management of patients with OSA published extensive guidelines aimed at reducing morbidity and mortality. Improved diagnosis pre-operatively could aid in proper compliance with these guidelines. These recommendations include preferential use of regional analgesia, reduction in systemic opioids, monitoring of oxygen saturation and nonsupine posture. The mainstay of treatment for OSA is a positive pressure airway device such as Continuous Positive Airway Pressure (CPAP) or in severe cases Nasal Intermittent Positive Pressure Ventilation (NIPPV). Post-operatively continuation of these treatments in patients with known OSA is often recommended. Some authors have demonstrated reductions in Apnea-Hypopnea Index postoperatively through the use of CPAP. However, a recent meta-analysis evaluating the effect of pre-operative or post-operative CPAP in patients with OSA concluded that the use of CPAP did not reduce post-operative adverse events. Given the projected increase in demand for joint arthroplasty, the ever-increasing incidence of obesity, the ambiguity surrounding the topic and the potential to clinically impact post-operative morbidity, mortality and health care costs, shows the need for further studies.

A randomized single blind clinical trial, with a larger sample size than previous studies , to evaluate the effectiveness of injection snoreplasty in the treatment of patients with snoring and obstructive sleep apnea/hypopnea syndrome (OSAHS) compared to oropharyngeal exercises, a low cost therapeutic modality.

Many researches have shown that patients with Obstructive Sleep Apnea (OSA) and often also the family members have a decreased quality of life, problems related to the sexual sphere, depressive disorders and anxiety problems. To date still remains controversial the relationship between OSA and quality of life, also the link between sleep apnea syndrome and depression is unclear. In adult patients with OSA the treatment of choice is the application of a continuous positive airway pressure (CPAP: Continuous Positive Airway Pressure) at the opening of the airways. With the CPAP treatment the sleep normalizes and daytime sleepiness fades or disappears. Many studies have shown that this treatment determines improvement of the medical and psychological status. However, the rate of non-adherence to treatment reported in the literature is about 46-83%, considering as adherence the use of CPAP for at least 4 hours per night. A recent study has shown that CPAP used as a single treatment in patients with OSA and depression, has reduced the depressive symptoms but in a significant percentage of patients (42%), the depressive symptoms remained unchanged or worsened. At the present time have not been published, to our knowledge, studies concerning the effectiveness of the combined treatment of CPAP and psychological support on the mood and on the quality of life OSA patients. Therefore the aim of this study is to evaluate the effects of the combined treatment with CPAP and psychological intervention with cognitive behavioural therapy on the mood and on the quality of life of OSA patients.
