Evaluation of the effectiveness of two different methods for the prevention of microbial colonization in nebulizers: Randomised controlled trial

Abstract

Objective: In this study two different methods were used to prevent microbial colonisation of nebulizer elements and the results were evaluated. Methods: The study was conducted as a randomized controlled semi-experimental study. The data were collected at the pediatrics department of a hospital in the city in western Turkey. A total of 120 pediatric patient using nebulizer treatment at least twice daily and their mothers were included in the study. The pediatric patients were divided into 3 groups. In one group no intervention was made (control group). In another group, nebulizer masks and sets were changed once every 24 hours. In the third group, masks were washed once daily in soap and water. In all groups swab samples were taken every 24 hours and examined under laboratory conditions. Results: Results showed that there was 10.8% microbial growth in the control group and 2.5% microbial growth in the 24-hour change group. No growth was detected in the wash group. Conclusion: As a result of this study, it is recommended that nebulizer elements are washed once daily with soap and water and dried on a clean towel in order to prevent contamination.
