AbstractDuring a 12-month period ending on November 30, 1988, data were collected on 2468 pediatric patients with wheezing who visited a pediatric ED. Cohort characteristics included: sex (64% male, 36% female), history of prematurity (12%), evidence of concurrent infection (82%), taking theophylline (35%), taking beta adrenergics (60%), taking cromolyn (6%), and taking corticosteroids (4%). The hospitalization rate was 10.5%. Seasonal variations, weather, air quality, and infections appeared to have significant effects on the daily variation of wheezing exacerbations. Initial oxygen saturation (OSAT) correlated with disease severity as measured by hospitalization risk and the number of bronchodilator treatments required in the ED. A suggestion for categorizing the treatment of asthma based on past history is proposed. Using this system in conjunction with pulse oximetry, wheezing severity and appropriate therapy can be more objectively determined.
