The child with simultaneous stridor and wheezing.

We describe 25 patients with simultaneous stridor and wheezing. Twelve patients presented to the emergency department of The Children's Hospital of Denver over a two-year period; we found an additional 13 in a review of the literature. A combination of two disorders produced stridor and wheezing in six patients, with one condition in the extrathoracic airway and one in the intrathoracic airway. The remaining 19 patients had single lesions, nine with obstruction of the extrathoracic airway and 10 with obstruction of the intrathoracic airway. The causes of stridor and wheezing in these 19 patients fell into three general categories: (1) congenital lesion affecting the airway (eight patients); (2) foreign body in the airway or esophagus (nine patients); and (3) acquired lesion affecting the airway (two patients). All eight patients with congenital lesions developed symptoms by four months of age. All nine patients with an airway or esophageal foreign body were between five and 30 months of age. The history may be misleading, and the physical examination often cannot discriminate among the various likely diagnoses. However, the addition of four plain x-ray views (lateral neck, posteroanterior and lateral chest, and forced expiratory chest) located the site of obstruction in 18 of 25 patients. Barium swallow identified the two patients with vascular rings. Four patients underwent endoscopy to determine the site of obstruction. We make recommendations for evaluation of these patients.
