Abstract
INTRODUCTION: Several drugs are in use for nebulization in children with acute bronchiolitis and no study has yet been conducted to compare the treatment outcome of nebulized ipratropium bromide and nebulized 3% hypertonic saline in Pakistan. OBJECTIVE: The objective was to compare the treatment outcome of nebulized hypertonic saline and ipratropium bromide in children with acute bronchiolitis. SETTING: Department of Pediatrics. STUDY DURATION: October 2019 to March 2020. SUBJECTS AND METHODS: A total of one hundred (n=100) children of either sex diagnosed with acute bronchiolitis were enrolled and randomized either to be nebulized with 3% hypertonic saline or ipratropium bromide. Outcomes were assessed in terms of respiratory rate, heart rate, and SpO(2) and respiratory distress assessment instrument score at different time intervals, length of hospital stay, and need of admission. RESULTS: Respiratory rate and SPO(2) improved significantly at 60 min and 24 h, respiratory distress assessment instrument improved significantly at 30 min, 60 min, and 24 h after the treatment in patients who were nebulized with hypertonic saline when compared to those nebulized with ipratropium bromide. The length of hospital stay was significantly shorter (2.63 vs. 3.82 days, P=0.008) and a lesser number of patients needed hospital admission (22% vs. 44%, P=0.019) in patients who were nebulized with hypertonic saline when compared to those nebulized with ipratropium bromide. CONCLUSIONS: Nebulization with 3% hypertonic saline resulted in significant improvement in symptoms, a shorter duration of hospital stay, and a lesser number of hospital admissions as compared to nebulization with ipratropium bromide in children with acute bronchiolitis.
