Abstract
The objective of this study was to compare the effect of L-epinephrine plus dexamethasone vs. dexamethasone for treatment of croup in children. A randomized, double-blind clinical trial was implemented on 174 patients with croup, aged from 6 months to 6 years, and admitted to the Amir Kabir Pediatric Hospital (Arak, Iran). After randomized allocation, patients were administered dexamethasone, and then, they received either saline or L-epinephrine. Westley croup scores, heart rate, respiratory rate, and blood pressure were recorded every half an hour for a total of 120 min. There was a significant difference in mean of croup scores between two groups (P < 0.009). In addition, a significant difference was seen on mean of heart rate between two groups (P < 0.026). Our results showed a considerable difference in reduction of velocity of croup scores in patients who received nebulized L-epinephrine compared to patients who received placebo.
