Not enough recruitment in th trial

Combined use of inhaled corticosteroids and long-acting β-agonists (LABAs) as the controller and the quick relief therapy termed single maintenance and reliever therapy (SMART) is a potential therapeutic regimen for the management of persistent asthma. A recent systematic review supports the combined use of inhaled corticosteroids and LABA as both the controller and quick relief therapy (SMART) among patients aged 12 years. In Emergency room (ER), Meta-analysis showed that using salbutamol (or albuterol) by meter doses inhaler (MDI) with a valved holding chamber (VHC) in children with moderate-severe acute asthma exacerbation was more effective, that is, fewer hospital admissions, more clinical improvement, and had fewer adverse effects (tremor and tachycardia) than salbutamol by nebulizer. Therefore, several international guidelines recommend the use of salbutamol by MDI rather than by nebulizer for moderate-severe asthma exacerbations. In children older than 8 years old, dry-powder inhaler (DPI), a device that delivers medication to the lungs in the form of a dry powder is currently used for maintenance and reliever therapy rather than MDI. In this context, we aim to assess the use of combined inhaled corticosteroids and long-acting β-agonists (LABAs) as a quick relief therapy in children older than 8 years old presenting at the ER with moderate asthma exacerbation. Acute asthma patients who had severe exacerbation were excluded from this study (these patients receiving systematically continuous nebulized salbutamol and/or intravenous salbutamol upon their arrival)
