Of interest are the variables which did not exert an appreciable effect in predicting outcome in our patient population. Studies in children have previously shown that the patient s age is not predictive of hospitalization, and our study confirms this finding. Likewise, the duration of the current asthmatic attack, and the number of previous admissions, were not predictive of the need for hospitalization. buy asthma inhalers
These observations are in agreement with those of certain investigators, but at variance with those of others. With respect to the value of Sa02 measurements in predicting outcome, our data partially validate those of Geelhoed et al that patients with Sa02 ^91 percent should be hospitalized. However, only 38 percent of the children who were hospitalized in our study had Sa02 values ^91 percent (Fig 1). Furthermore, the patients with Sa02 ^91 percent also had high clinical scores indicating apparent severe disease. Although Sa02 measurements were not predictive of outcome in our study, we would like to emphasize that the measurement of Sa02 has an important role in the management of acute childhood asthma as it allows patients who require supplemental oxygen to be identified.
