A 62-year-old woman (148 cm, 48.5 kg) with a history of bronchial asthma underwent an emergency appendectomy. Ten days before the operation she developed symptoms of wheezing while under asthma medication. An endotracheal tube (7 mm) was inserted after the induction of general anesthesia with intravenous injection of fentanyl 100 micrograms, propofol 100 mg and vecuronium 10 mg under Sellick's maneuver. Anesthesia was maintained with 1% sevoflurane with oxygen 6l-min-1 just after intubation, but bilateral lung sound soon became weaker and ventilation difficult. Based on a diagnosis of bronchoconstriction, we started hyperventilation with 3% sevoflurane. Ventilation returned to normal after about 5 minutes. Percutaneous O2 saturation was maintained at 100% during this episode, but the BIS transiently rose to 82. Anesthesia was maintained with 2% sevoflurane and 50% nitrous oxide balanced with oxygen, and 250 mg aminophylline was administered. Upon completion of the operation, the endotracheal tube was removed without any events. The patient gave no sign of awareness during the operation. When severe bronchoconstriction prevents the absorption of anesthetics from the lung alveoli, additional intravenous anesthetics should be administered to maintain stable amnesia.

Background. High-dose inhaled steroid therapy has been shown to be effective in children and adults with asthma exacerbations. However, few reports are available regarding its efficacy for asthma exacerbations in younger children. Objective. In this study, we administered high-dose nebulized budesonide therapy for mild asthma exacerbations in children < 3 years of age and compared its efficacy and safety with systemic steroid therapy. Methods. This study included children < 3 years old with mild asthma exacerbations. Patients were randomly assigned to two groups: the BIS group was given 1 mg of nebulized budesonide twice daily, and the PSL group received prednisolone 0.5 mg/kg iv three times daily. Days to disappearance of wheezing, days of steroid use, days of oxygen use, serum cortisol level, and incidence of adverse events during treatment were compared between the groups. Result. Wheezing disappeared after an average of five days, and steroids were administered for an average of five days in both groups, with no significant difference in days of oxygen use. Serum cortisol levels at initiation and during the course of treatment remained unchanged in the BIS group, and were decreased in the PSL group; however, the decrease in the latter group was not pathologic. Conclusion. For children < 3 years old with mild asthma exacerbations, high-dose nebulized budesonide therapy is equally as effective as systemic steroid therapy.
