Asthma in children is associated with significant morbidity. Children with severe asthma are at increased risk for adverse outcomes including medication-related side effects, life-threatening exacerbations, and impaired quality of life. In the study, an asthmatic child with a recent cold, received general anesthesia for emergency surgery centered on sevoflurane, corticosteroids and ketamine. The purpose of this study is to demonstrate the beneficial effects of the combination of sevoflurane, ketamine and corticosteroids in asthmatic children and to prevent complications when they are given general anesthesia for emergency surgery.
