Study Objective: To determine whether children with developmental delay would have closer apposition of upper airway tissues during sedation, perhaps because of poor coordination of upper airway musculature. Design: Case-control and retrospective chart review. Setting: Tertiary-care pediatric teaching hospital. Patients: 40 children 3 to 6 years of age, with and without a diagnosis of developmental delay. Measurements: Subjects received only pentobarbital sedation by a protocol. Magnetic resonance imaging (MRI) scans of the head were reviewed, and transverse airway diameters at the soft palate and tongue were determined from midline sagittal images. Main Results: Age, weight, sedative dose, MRI window level, and window width were not different between patients with and without developmental delay. We found the airway diameter at the level of the soft palate was decreased 40% in children with developmental delay compared with those children without delay, 3 mm (1.4, 5.5 interquartile range) versus 5 mm (3, 8); p = 0.035, power 76%. Conclusions: The anteroposterior oropharyngeal airway diameter was smaller in children with developmental delay than in those without developmental delay, in static MRI images. It is possible that children with developmental delay are at higher risk for airway obstruction during sedation. (C) 2001 by Elsevier Science Inc.
