Difficult Airway, Obstructive Sleep Apnea
Conditions
Brief 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.
Interventions
Ultrasound to measure hyo-mental distance, neutral (Frankfort) position, maximal extended neck position to calculate ratio, width of the tongue between the lingual arteries, and tonsillar size (bilateral).
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
