[A case of intractable status asthmaticus treated by isoflurane inhalational anesthesia and bronchial lavage].
A case of severe asthmatic attack treated by isoflurane inhalational anesthesia and bronchial lavage is reported. A 24-year-old woman was admitted to our hospital with severe asthmatic attack. Although she was treated by intravenous administration of aminophylline and corticosteroids, pulmonary function and consciousness deteriorated. Therefore, she was intubated nasally and mechanically ventilated by IPPV with administration of aminophylline, corticosteroids and epinephrine. Despite this treatment, she remained in status asthmaticus with high airway pressure and barotrauma causing pneumomediastinum and subcutaneous emphysema. On the 3rd hospital day, a system was arranged so that isoflurane could be given in an air and oxygen mixture, and administration was started with a concentration of isoflurane of 1.5%. In addition, bronchial lavage via bronchoscopy was performed in order to clear any mucous plugs. After 24 hours, there was marked improvement of wheezing, airway pressure and arterial blood gas level. Eventually, she was weaned from the ventilator on the 6th hospital day without significant side effects. The use of halothane inhalational anesthetic treatment for status asthmaticus is widely known, but it has serious side effects such as arrhythmia and liver injury. Isoflurane may be the inhalational anesthetic agent of choice in the treatment of status asthmaticus.
