Objective: Pulmonary function test(PFT) during forced expiration are currently accepted as the most important indices in the assessment of airway obstruction in patients with acute bronchial asthma. Some recent reports showed that arterial oxygen saturation(SaO2) is also useful for the measurement of severity and outcome of acute asthma. In this study we compared the reliability of PFT and SaO2, in assesaement of severity and prognosis of acute asthma and therapeutic efficacy of bronchodilators as well. Methods- We studied on 35 cases of bronchial asthma patients who were admitted to the department of pediatrics, Koryo General Hospital from November, 1991 to June, 1993. We performed PFT with microapirometer and pulse oxymetry to obtain SaO2 for all patients everyday during hospitalization. Results: 1) Values of PFT in asthmatic children were improved after nebulization treatment. But the increment of SaO2 after nebulization treatment was insignificant. 2) Values of PFT in patients who had severe wheezing at admission(wheezing score>g were significantly lower than those of patients with mild wheezing on admission(p<0.05). But the difference of SaO2 between two groups was not observed, 3) Values of PFT(except PEFR) in patients who had longer hospitalization(R 4days) was significantly lower than that in patients who had shorter hospitalization(p<0.05). But the difference of SaO2 between two groups was not observed. 4)Values of PFT and SaO2 in asthmatic children were significantly increased at dischage compare to those on admission(p<0.01). Conclusions: At present, pulmonary function test using portable microspirometer seems to be more convenient and useful for the assessment of airway obstruction in childhood asthma. In this study, we concluded that values of PFT were more accurate than SaO2, measurement in assessment of severity and prognosis of acute asthma in childhood.
