Filter by:Obstructive sleep apnea syndrome (OSAS)is a sleep breathing disorder manifested by complete apnea or partial hypopnea obstruction of the upper airway, which often remains undiagnosed and untreated (Kuczynski, W., 2019). These episodes, which should be more than 5 per hour and last at least 10 s, can lead to a sleep fragmentation and hypoxia (Huon, L.-K.A., 2017). OSAS predominantly affects 26% of individuals between 30 and 70 years in the U.S (apnea hypopnea index ≥5 events per hour) (Schwartz, M., 2018). Obstructive sleep apnea it is increasingly recognized as an independent risk factor for cardiac, neurologic, and perioperative morbidities. Yet this disorder remains undiagnosed in a substantial portion of our population. It is imperative for all physicians to remain vigilant in identifying patients with signs and symptoms consistent with OSA (Park, J. G., 2011). The test of hypothesis is to design a clinical prediction model of obstructive sleep apnea from collected data of the patients having symptoms of obstructive sleep apnea and the results of their sleep study
The research project consists of an observational study. Obstructive Sleep Apnea (OSA) is a condition characterized by recurrent episodes of upper airway collapse during sleep, leading to decreased blood oxygen levels and disruptions of normal sleep patterns. Estimates of its prevalence vary, but its impact on patients' quality of life is evident. The research aims to explore the perception and awareness of the disease and its impact on the individual and couple's lives of patients with OSA and their bed partners, to assess patients' perceptions of the disease and symptoms, as well as their bed partners' perceptions. Moreover, psychological aspects of living with OSA, such as perceived stress, depression, anxiety, sleep quality, daily sleepiness will be studied to observe the association with Continuous Positive Airway Pressure (CPAP) adherence.
Background: To compare the efficacy of tonsillectomy and expansion sphincter pharyngoplasty (ESP) in the surgical treatment of obstructive sleep apnea (OSA). Methods: Patients with Friedman grade III-IV tonsil hypertrophy and OSA diagnosed with polysomnography were separated into two groups according to the surgery performed, as the classic tonsillectomy group (Group 1) and the ESP group (Group 2). The primary endpoint of the study was to determine the Apnea-Hypopnea Index (AHI) value. The preoperative and postoperative AHI scores and the decreases in these scores were noted. The change in AHI was calculated as a percentage (preoperative AHI - postoperative AHI/ preoperative AHI x 100) and the two groups were compared. An AHI value of <10 events/hour was accepted as cure.
the investigators aim in this study is to investigate the effects of aerobic and oropharyngeal exercises on sleep quality in patients with Obstructive Sleep Apnea Syndrome (OSAS).
This study aims to identify how many patients who have atrial fibrillation, also have sleep apnoea. This is important because sleep apnoea can be a trigger to atrial fibrillation and it can be corrected with a simple intervention. Therefore it is important to understand its prevalence (how many patients with atrial fibrillation are affected by it). Also, obesity and sleep disorders are often associated, therefore the evolution of atrial fibrillation is studied in patients who also have obesity and have lost weight compared with patients who did not loose any weight or are not obese. As medications or therapy are not changed, this is an observational study.
A comparative study on the safety and efficacy of esmketamine versus Dexmedetomidine during drug induced sleep endoscopy in children with positional obstructive sleep apnea: A consort-prospective, randomized, controlled clinical trial
Chronic obstructive pulmonary disease (COPD) is a common disease that endangers people's health, causing severe economic and treatment burdens. Sleep breathing disease, as a complication of COPD, increases the hospitalization rate and mortality of COPD. At present, community doctors have insufficient knowledge of COPD and its complications, and they also lack standardized screening and related disease management capabilities. This trail intends to use IoT medical technology to screen for COPD combined with sleep breathing diseases. It can establish a two-way referral channel between primary community hospitals and higher-level hospitals, which provides early warning services for COPD combined with sleep breathing diseases. This trial explores the impact of sleep breathing disease on COPD's acute exacerbation, which improves the understanding of COPD patients combined with sleep breathing diseases. It also improves COPD management and its complications control at the community-level and reduces COPD patients' potential risks and treatment burdens. It also explores tiered diagnosis and treatment models for COPD, promotes the construction of intelligent IoT infrastructure, and enhances standardized diagnosis and treatment of COPD at the grassroots level in China.
Light to moderate sedation is recommended during surgery with spinal anesthesia . This study is exploring which sedation drug is better, midazolam or dexmedetomidine for transurethral resection of bladder and prostate in patients with or without high risk for obstructive sleep apnea (OSA). Patients were divided in two groups regarding OSA risk, and each group received midazolam or dexmedetomidine for sedation. Investigators observed intraoperative complications of airway and factors that are disturbing surgeon(movement due to participants coughing and restlessness) because one could puncture bladder or prostate and cause perforation.
Continuous positive airway pressure (CPAP) is considered the gold standard treatment for patients with moderate to severe obstructive sleep apnea (OSA). Nasal and oronasal masks are often used interchangeably and are generally believed to be equally effective; the choice of interface for OSA therapy remains largely based on clinical judgement and patients preference. However, there is increasing evidence that CPAP delivered by an oronasal mask may be less effective, requires more pressure and are worse tolerated than nasal mask. Patients with OSA on oronasal mask are also less adherent to CPAP. Some authors have suggested that in some subjects, the CPAP was not effective when an oronasal mask was used. Moreover when pressures are increased to overcome the obstruction, a paradoxical obstruction may take place. Specific mechanisms explaining upper-airway obstruction events remain unclear and it is not known how many patients exhibit this behavior. This observational retrospective study is designed to compare a group of patients with obstructive sleep apnea with persistent obstructive events using oronasal masks during CPAP, that were fully recovered with the shift to nasal one with the same or also lower pressure, versus a control group of patients who did not report obstruction with oronasal masks. Aim of the study was to find differences in term of clinical, anatomical and physiological characteristics between these two groups.
To compare two different clinical strategies in order to evaluate the impact of prophylactic heated humidification on OSA patients' compliance to CPAP therapy.
