Study summary

This is a novel approach to assess the use of ultrasound to support the identification of obstructive sleep apnea syndrome (OSAS) on a screening questionnaire, and potentially to predict a difficult pediatric airway. The investigators hope to determine if a combination of simple bedside clinical tests can be used to identify OSAS in patients who present for surgery with clinical signs of OSAS but without a formal polysomnography.

  • Other
    Predictive Obstructive Sleep Apnea

    The following 6 questions will be asked during the preoperative visit: 1. While sleeping, does your child snore more than half the time? 2. While sleeping, does your child always snore? 3. Have you ever seen your child stop breathing during the night? 4. Does your child occasionally wet the bed? 5. Did your child stop growing at a normal rate at any time since birth? 6. Is your child overweight

What researchers measure

Primary outcomes

  1. Hyo-mental distance

    The distance from the hyoid bone to the mentum to predict difficult airway.

    Time frame: 5 minutes before surgery starts

Secondary outcomes

  1. Tongue width

    Width of the tongue between the lingual arteries.

    Time frame: 5 minutes after being intubated in surgery

  2. Tonsil size

    Size of tonsil (bilateral)

    Time frame: 5 minutes after being intubated in surgery

  3. Questionnaire

    6 predictive OSA questions

    Time frame: 30 minutes before surgery

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 7, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
