Active clinical trials for "Sleep Apnea Syndromes"

The researchers are investigating if the Self-Supporting Nasopharyngeal Airway (ssNPA) device can be used in the treatment of obstructive sleep apnea in children with Hypotonic Upper Airway Obstruction (HUAO).

The aim of this study is to determine if treatment with Medical Air (21% oxygen in room air) compared to supplemental oxygen (100% oxygen) will lead to similar improvements in the central apnea-hypopnea index (CAHI) for infants with Prader-Willi Syndrome. Despite the vast amount of research investigating the cause of central sleep apnea, there remain gaps in knowledge, lending to further research efforts. The decision to compare oxygen to medical air is based on several theorized mechanisms. The first of which is the supposition that provision of medical air may act as an arousal stimulus for the hypothalamus, thereby preventing sleep disordered breathing. Secondly, the hypercapnic challenge performed by Livingston et al demonstrated a delayed hypercapneic arousal response in PWS subjects despite simultaneous hyperoxia, leading us to question if therapeutic oxygen really plays a significant role in treating CSA. Lastly, the delivery of medical air via nasal prongs may provide sufficient arousal to terminate the cycle of events leading to central apnea, as described by Urquhart et al. A deeper understanding of central sleep apnea is essential to ameliorating its adverse sequelae, which include symptoms of ADHD, impaired attention, behavioral problems, and academic difficulties.

The goal of this treatment study is to determine if doing lateral pharyngoplasty with tonsillectomy is better for children than doing tonsillectomy alone. The main questions it aims to answer are: Do children experience less pain after surgery when lateral pharyngoplasty is performed with tonsillectomy compared to tonsillectomy alone? Do children eat/drink better when lateral pharyngoplasty is performed with tonsillectomy compared to tonsillectomy alone? Is there a lower risk of bleeding after tonsillectomy when lateral pharyngoplasty is performed? Researchers will compare children undergoing tonsillectomy and lateral pharyngoplasty with children undergoing tonsillectomy alone to see if the participants experience less pain, better oral intake, and less bleeding complications after surgery. Parents of participants will be asked to record pain scores and pain medications given, approximate amounts of daily oral intake, and any complications after surgery.

Patients meeting the criteria of obstructive sleep apnea were included, and all patients signed informed consent, which met the requirements of the ethics Committee of our unit. All subjects were hospitalized patients. Subjects were randomly enrolled into High-flow Nasal Cannula Oxygen Therapy group or Continuos Positive Airway Pressure group for 1 month of treatment. Sleep respiration monitoring data including AHI, blood oxygen saturation decline index (ODI) and minimum blood oxygen saturation were recorded before and after treatment. After one month of the first stage of treatment, patients voluntarily continued to receive treatment and observers were included in the second stage of treatment. HFNC group and CPAP group continue to receive corresponding treatment for 6 months.Before and after the study, sleep respiratory monitoring datas,treatment failure rate，good compliance rate are recorded.

Patients meeting the criteria of obstructive sleep apnea were included, and all patients signed informed consent, which met the requirements of the ethics Committee of our unit. All subjects were hospitalized patients. Subjects were randomly enrolled into High-flow Nasal Cannula Oxygen Therapy group or Continues Positive Airway Pressure group for 3 days of treatment. Sleep monitoring was performed on the first and fourth day of enrollment.

The craniofacial abnormalities found in infants and children with cleft palate (CP) lead to increased risk of obstructive sleep apnoea (OSA). In children and adults sleep position is known to influence the patency of the airway during sleep. Altering sleep position in infants with CP may offer a 'low-cost, high impact' intervention to limit the negative impacts of OSA on child development. Children with CP are at increased risk of impairment in learning, memory and cognition, with OSA representing an additional risk to cognitive development. Infants with CP are at risk of poor weight gain and 'failure to thrive', which can be further exacerbated by co-existing OSA. The design and conduct of the proposed randomised controlled trial will benefit from lessons learned from both the feasibility and other previous studies. Investigators demonstrated that existing advice given about sleep position varied significantly with some centres recommending back-lying and others side-lying. Sample size calculations were based on this multi-source data. Parents in the feasibility study knew that sleep position advice for infants with CP changes regularly. They understood why not adhering to 'national guidance' (DoH 2009, Back to Sleep) could be necessary as their infants are "different to normal infants". How will this study benefit infants with cleft palate and their parents? The proposed study will eliminate the current uncertainty and variability in advice provided to parents of infants with CP, whilst potentially limiting the negative impact of OSA on development. This work has been prioritised and received unanimous support from Cleft Lip and Palate Association (CLAPA), Craniofacial Society Great Britain and Ireland (CFSGBI) and Clinical Nurse Specialists. Aim.To determine the clinical effectiveness in infants with CP of side-lying as compared to back-lying sleep positioning in reducing oxygen desaturation resulting from OSA.

One of main problems in the management of sleep-disordered breathing (SDB) in children and young adults is their screening, and the absence or the weak correlation between clinical symptoms and polysomnography (PSG). It may be useful to use additional measures together with PSG to improve the detection and characterization of respiratory events during sleep and/or correlation with clinical signs of SDB. The primary objective of the study is to determine whether psychological and neuropsychological test scores correlate with diagnostic PSG results.

The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke or high risk TIA (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.

The LinguaFlex™ Tongue Retractor (LTR) is an investigational medical device that is inserted into the tongue to lessen its backward movement during sleep. This helps to keep the airway open during sleep so that the tongue doesn't block the airway causing obstructive apnea or narrow it enough to cause snoring. This study will monitor the effectiveness of the LTR device in the reduction of Obstructive Sleep Apnea and snoring over the course of a one-year treatment period.

Study name: Validation of a Ring-type Wearable Device for Blood Oxygen Monitoring and Obstructive Sleep Apnea Syndrome Screening in Adult Chinese. Objective: 1) To examine the accuracy of blood oxygen monitoring assessed via a ring-type wearable device in comparison to traditional finger clip pulse oximeter; 2) To assess the agreement between the ring-type wearable device and PSG monitor on OSAS screening.
