Status asthmatics is characterized pathologically by bronchial smooth muscle spasm, and mucous plug-ging of the small airways. Clinically, it is character-ized by the disturbance of gas exchange. In severe cases, unresponsive to standard therapy (including oxygen, epinephrine, aminophylline and steroids, artificial ventilation, tracheobroncial lavage and in-halation), anesthetic therapy shoud be started without delay. Inhalation anesthetics, halothane or ether, have potent bronchodilating properties which facilitate the removal of mucous plugging.

We reported nine cases with status asthmatics treated by inhalation anesthetic therapy. Halothane (0.5~3.0%) was used in all cases, ether (1.5~3.0ml/kg) was used in five cases. The duration of anesthesia was 0.5 to 13.5 hours. In three halo-thane anesthesia cases, blood pressure was reduced before there was improvement in wheezing, so we were forced to change halothane to ether. In all cases, the symptoms of status asthmatics were improved, but two patients died due to other complications.

We recommended the following method, viz that halothane be administered at first, and be changed to ether in order to maintain circulatory movement.
