[Treatment of life threatening asthma with isoflurane].

Three patients, one adult, one adolescent and one child, with previous history of asthma difficult to treat and frequent acute crisis, were hospitalized with clinical signs of Life Threatening Asthma (LTA) refractory to intensive treatment, including intubation and mechanical ventilation, being treated with and inhaled anesthetic: Isoflurane. All patients responded satisfactorily to such treatment at a concentration varying from 0.5 to 1.5% and none of them suffered adverse reactions to the medication. The immediate therapeutic effect and the absence of intensive care are factors that indicate the use of Isoflurane.
