Randomized trial of salbutamol in acute bronchiolitis

Area of Science:

• Pediatrics
• Pulmonology
• Pharmacology

Background:

• Acute bronchiolitis is a common viral respiratory infection in infants.
• Treatment options for bronchiolitis are limited, with a focus on supportive care.
• The efficacy and safety of bronchodilators like salbutamol remain debated in this population.

Purpose of the Study:

• To evaluate the safety and efficacy of nebulized salbutamol for acute bronchiolitis in young children.
• To assess the impact of salbutamol on clinical scores, respiratory rate, and oxygen saturation.

Main Methods:

• A randomized, double-blind, placebo-controlled trial involving 83 children (median age 6 months).
• Participants received either nebulized salbutamol or placebo via nebulization at 30-minute intervals.
• Outcomes included respiratory rate, pulse oximetry, and a clinical score assessing wheezing and retractions.

Main Results:

• Salbutamol treatment led to significantly greater improvement in clinical scores after the first dose (p=0.04).
• No significant difference in oxygen saturation was observed between groups (p=0.74).
• A slight increase in heart rate was noted in the salbutamol group after two treatments (p=0.03).

Conclusions:

• Nebulized salbutamol is safe and effective for the initial management of acute bronchiolitis in infants and young children.
• Salbutamol demonstrates clinical benefit in improving symptoms of bronchiolitis.
• Further research may explore optimal dosing and long-term effects.
