wo bronchodilatation tests with thier pulmonary function indexes were observed in patients withasthma. The results showed that both adrenaline injection and ventolin respirator solution inhalationfrom oxygen-driven nebuliser can reduce bronchoconstriction

improving lung ventilatory function.The former had side effects on cardiovascular system influencing heart rate and blood pressure

andthe latter no obvious side effects

The results of pulmonary function tests in two znethods were simi-lar.It is concluded that ventolin respiration solution inhalation with nebuliser can completely replaceadrenaline hypodermic injection when broncholatation test was done

and it is worthwhile spreading itin clinical practice
