MDI with DIY Spacer versus Nebulizer for Bronchodilator Therapy in Children Admitted with Asthmatic Attack.

Inhaled bronchodilator treatment given via the pressurized metered-dose inhaler (pMDI) with spacer has been recommended for an acute asthma treatment. Unfortunately, most of commercially available spacers are at high cost while a do-it-yourself (DIY) spacer has lower cost as it is made from plastic bottle and siphon pump which are inexpensive and easilyfound materials.This study aims to compare treatment response in nebulizer and DIY spacer used for asthmatic children.A prospective, randomized control study was conducted in children aged 1-15 years old hospitalized for mild to moderate asthmatic attack at Thammasat University Hospital between June 2014 and March 2015. The patients were divided into 2 groups, receiving β2-agonist via nebulization and via pMDI with DIY spacer. Their vital signs and oxygen saturation were monitored and asthma scores were also recorded at admission, 24 hours, 48 hours, and before discharge. The satisfaction of equipment use was evaluated employing questionnaires.40 childrens were enrolled with male at 72.5% and mean age at 3.1±1.6 years old. There was no significant difference in efficacy of β2-agonist among 2 groups when comparing in consideration of vital signs, oximetry, asthma scores and hospital stay. However, there were significantly different on side effect in which the DIY spacer had less tachycardia and agitation. Satisfaction of parents and healthcare workers were higher in DIY spacer.MDI with DIY spacer was able to be used effectively when compared with nebulization to treat mild to moderate acute exacerbations of asthma in children admitted in hospital.
