What is the purpose of this trial?

This trial tests two sedation drugs, dexmedetomidine (also known as Precedex) and propofol, to assess their effects on the upper airway during sleep in children with obstructive sleep apnea (OSA). Researchers aim to determine if these drugs cause different levels of airway collapse and if this collapse relates to OSA that persists after tonsil and adenoid removal surgery. Children diagnosed with OSA and considered for surgery might be suitable participants, especially if they have other factors that could lead to ongoing sleep apnea. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group, providing valuable insights into potential improvements in managing OSA.

Will I have to stop taking my current medications?

The trial information does not specify whether participants need to stop taking their current medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that dexmedetomidine is generally safe for children with obstructive sleep apnea (OSA). It helps keep them calm while maintaining important reflexes that clear their airways. Some studies note that children may take longer to wake up after surgery when sedated with dexmedetomidine, but it remains safe.

Propofol is also commonly used for sedation, but it has a smaller safety margin, especially for older children and girls. It can cause brief pauses in breathing when first administered. Although propofol is usually not used for deep sedation in children with OSA, it can be safe for those with central sleep apnea, where the brain doesn't send the right signals to breathe. Both treatments have been used before, but each has specific safety considerations. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for pediatric obstructive sleep apnea because they offer potentially safer and more effective sedation options. Dexmedetomidine is unique because it provides sedation with less respiratory depression compared to traditional sedatives, which is crucial for children with sleep apnea who already have breathing challenges. Propofol, while commonly used, is being studied for its ability to provide quick and deep sedation, which can be beneficial during brief procedures. These treatments are being explored to see if they can better manage sedation while minimizing risks for young patients with this condition.

What evidence suggests that this trial's treatments could be effective for pediatric obstructive sleep apnea?

This trial will compare dexmedetomidine and propofol sedation for pediatric obstructive sleep apnea. Studies have shown that dexmedetomidine may be a suitable option for children with obstructive sleep apnea (OSA) during sleep endoscopy. It generally affects the main features of OSA less and doesn't significantly lower oxygen levels, potentially maintaining airway reflexes better while the child is sedated. In contrast, propofol, administered to participants in another arm of this trial, can sometimes cause more airway collapse and lower oxygen levels, despite its faster onset of sedation. These findings suggest that while both drugs are usable, dexmedetomidine might better prevent additional airway issues during these procedures. ^{1 2 3 6 7}

Are You a Good Fit for This Trial?

This trial is for children aged 3 to under 12 with obstructive sleep apnea confirmed by a sleep study. They should benefit from a sleep endoscopy before tonsil and adenoid removal surgery, especially if they are obese, have severe OSA, small tonsils but severe symptoms, are African American or over 7 years old. Kids who've had previous upper airway surgeries or have certain medical risks or allergies can't participate.

Published Research Related to This Trial

In a study of 117 children aged 1-18 with sleep disordered breathing, there was no significant difference in the frequency of ≥ 50% airway obstruction between those sedated with propofol and those sedated with dexmedetomidine during DISE procedures.

The results suggest that both sedatives are equally effective in assessing upper airway obstruction in children, indicating that the choice of sedative may not impact the findings of airway obstruction in this context.

Propofol versus dexmedetomidine during drug-induced sleep endoscopy (DISE) for pediatric obstructive sleep apnea. Kirkham, EM., Hoi, K., Melendez, JB., et al.[2021]

In a study involving 91 pediatric patients, dexmedetomidine was found to be a well-tolerated alternative sedative for non-intubated moderate or deep sedation, with a low incidence of serious adverse events.

While respiratory depression and hypotension were the most common treatment-emergent adverse events, they were manageable and consistent with dexmedetomidine's known safety profile, indicating its potential for safe use in children during elective procedures.

In a review of 5 randomized controlled trials involving 270 adults with obstructive sleep apnea, dexmedetomidine was found to have fewer adverse effects on respiratory function and resulted in higher satisfaction among endoscopic performers compared to propofol.

However, while dexmedetomidine showed better respiratory safety, it also had a higher risk of failed sedation, whereas propofol allowed for quicker onset of sleep but was associated with lower oxygen saturation levels and a greater risk of hypoxemia.

In a study of 24 pediatric patients undergoing airway reconstruction, dexmedetomidine was found to be well tolerated and safe, particularly for short-term intubation, with no significant adverse effects reported.

Dexmedetomidine may serve as a beneficial alternative to propofol for sedation during the periextubation period, allowing for easily reversible sedation, although further research is needed to explore its long-term safety and efficacy.

Intravenous dexmedetomidine is effective for sedation in mechanically ventilated patients and during procedures, reducing the need for additional sedatives like propofol or midazolam.

It is generally well tolerated, does not cause respiratory depression, and while it may lead to hypotension and bradycardia, these side effects typically resolve on their own.

Dexmedetomidine: a guide to its use for sedation in the US. Keating, GM., Hoy, SM., Lyseng-Williamson, KA.[2022]

In a study of 56 children with obstructive sleep apnea (OSA) who underwent drug-induced sleep endoscopy (DISE) using dexmedetomidine and ketamine, at least one site of obstruction was identified in all patients, regardless of whether their OSA was REM- or NREM-predominant.

Post-surgery, children with REM-predominant OSA showed significant improvements in their obstructive apnea-hypopnea index (oAHI), sleep efficiency, total sleep time, and oxygen saturation levels, indicating that DISE can effectively guide surgical interventions for these patients.
