255SPIROMETRY RESULTS IN CHILDREN WITH MILD TO MODERATE ASTHMA EXACERBATION AFTER TREATMENT WITH ORAL AND INHALED CORTICOSTEROIDS.Asthma is a chronic inflammatory illness of the airways that causes the most visits to the emergency room (ED) in children due to its aggravation. Bronchodilators and anti-inflammatory corticosteroids are commonly used to treat asthma exacerbations. Inhaled rapid-acting 2 agonists are the standard treatment for acute exacerbation .In circumstances where short-acting -agonist therapy has failed, oral corticosteroids (OCS) may be explored .Treatment with systemic corticosteroids is linked to lower admission rates , shorter hospital stays , and improved pulmonary index scores .Aside from these positive effects of OCS, there is a decline in drug acceptability and compliance after discharge from the emergency room due to potential side effects . Inhaled corticosteroids are being considered as a therapeutic option for these patients. Inhaled corticosteroids have recently been proven to have a protective impact on acute asthma exacerbations in a juvenile asthma population. The aim of this study is to assess changes in pulmonary function tests in children taking oral prednisolone and inhaled Budesonide for mild-to-moderate asthma exacerbation. There is a considerable discrepancy in the results of the PFT between groups before and after treatment. Oral nutrition, on the other hand, is beneficial to children. Prednisolone had a lot more than prednisone. an increase in peak expiratory flow (PEF). Taking a look at the results before and after. There was a considerable difference in each group. In both cases, there was an improvement in all metrics. PEF, on the other hand, had no significant differences between groups (p0.05). Compared to previously, there has been a shift after treatment.
