简要总结
Children with hypotonic upper airway obstruction have a high prevalence of severe obstructive sleep apnea, which if not treated has significant clinical consequence. Available treatment approaches, such as surgery and positive airway pressure, show limited efficacy and adherence. The multidisciplinary team has developed and now proposes to further test a non-surgical, well-tolerated nasopharyngeal airway device that in initial patients has resolved even extremely severe obstructive sleep apnea, and improved patient and family quality of life.
详细描述
There is a critical need for safe and effective treatment options for persistent obstructive sleep apnea (OSA) in patients with Hypotonic Upper Airway Obstruction (HUAO). HUAO encompass conditions such as cerebral palsy, hypoxic encephalopathy, syndromic tone anomalies, and neuromuscular disorders, and typically share a similar pattern of multisite upper airway collapse. OSA is characterized by recurrent episodes of partial or complete upper airway obstruction during sleep with associated arousals and/ or oxygen desaturations. Of hypotonic patients with symptoms of sleep disordered breathing, one quarter have moderate OSA, and more than half have severe OSA. Thus, not only are patients more likely to have OSA, but it is likely to be much more severe. Currently available treatment options, ranging from palliative care to tracheostomy, often fail to fully meet the needs of these patients. The multidisciplinary team has developed a dramatically effective non-surgical nasopharyngeal airway stent that has demonstrated good tolerability in hypotonic patients. This initial phase will test an enhanced version of the device for acceptability and tolerability. Critically, insertion, adherence, and compliance protocols will be optimized for preparation of the full trial.
This record originally included the Secondary Outcome Measure "Device Design". This Secondary Outcome Measure was removed during the results reporting process upon advisement of ClinicalTrials.gov reviewers, as it was not a directly health-related outcome.

入选标准
- •Children with HUAO: This includes those who newly diagnosed with OSA. These children will undergo overnight polysomnography to determine the presence of OSA (AHI>10 or AHI>5 with nocturnal hypoxemia defined as SpO2 nadir <=75%).
- •Obstructive sleep apnea on polysomnogram with AHI>=10
- •Presence of at least one symptom of OSA (such as snoring 3 or more nights per week, daytime sleepiness, or hyperactive/inattentive behaviors)
- •Post adeonotonsillectomy or those with contraindications to tonsillectomy.
- •obstructive sleep apnea on polysomnogram with AHI>=10
- •Tonsil size 2+ or smaller
- •Parent/caregivers willing and able to provide informed consent and child willing and able to provide assent, where appropriate.
排除标准
- •AHI ≤10 on polysomnogram without hypoxemia or AHI<5 with hypoxemia - any reason why ssNPA may not be suitable
- •Any medical reason why ssNPA therapy may not be suitable
- •Active COVID 19 infections
- •ETCO2 or TCO2 values >60 mmHg for >10% of sleep time on PSG
- •Psychiatric, medical, or social factors likely to invalidate assessments, make adherence with ssNPA highly unlikely or make local follow-up at 8 weeks unfeasible. Some psychiatric conditions may be provoked or exacerbated by OSA, and those most commonly implicated - Attention Deficit/Hyperactivity Disorder, Conduct Disorder, and Oppositional Defiant Disorder - will not be exclusions. However, more pervasive conditions such as severe autism will be excluded
- •Presence of supraglottic airway collapse or more distal airway stenosis or collapse (for example glottic, subglottic stenosis, or concern for distal airway stenosis or malacia)
- •Moderate/severe tracheobroncomalacia
- •Need for anticoagulative therapy
- •Bleeding disorder
- •Restrictive thoracic disorders
结局指标
主要结局
