The goal of this randomized controlled trial is to compare two different devices for the administration of the standard protocol drug. The main question it aims to answer is are metered dose inhalers with spacer device as effective as nebulization with salbutamol in treatment of childhood wheeze Children will be divided in two groups using block randomization method. Children in group A will be nebulizer group, treatment will consist of 3 puffs of a placebo MDI with a spacer, followed immediately by a standard dose of 0.15 mg/kg of salbutamol in 3 mL of isotonic sodium chloride solution delivered by an oxygen-driven nebulizer at a flow rate of 6 L/min. For patients in group B spacer group, treatment consisted of 3 puffs (90 pg per puff) of salbutamol MDI with a spacer, followed by 3 mL of nebulized isotonic sodium chloride solution. All treatments will be given at 20-minute intervals. For administration of the MDI, the investigator will dispense I puff of salbutamol or placebo into the spacer and held the mask on the child's face while the child breathed 5 to 6 times through the mask. This process will b-e repeated for a total of 3 puffs per treatment. All patients will be treated by the principal investigator, at end of treatment need for admission and pulmonary index will be noted.
