Nebulized hypertonic saline without adjunctive bronchodilators for children with bronchiolitis.

Area of Science:

• Pediatric Pulmonology
• Critical Care Medicine
• Respiratory Therapy

Background:

• Bronchiolitis is a common viral respiratory infection in infants.
• Hypertonic saline is increasingly used for bronchiolitis, but its safety without bronchodilators requires further evaluation.

Purpose of the Study:

• To determine the adverse event rate of nebulized 3% saline solution administered without adjunctive bronchodilators for infants hospitalized with bronchiolitis.

Main Methods:

• Retrospective cohort study analyzing medical records of infants (<2 years) hospitalized with bronchiolitis.
• Evaluated administration of nebulized 3% saline, associated adverse events, and clinical outcomes.
• Assessed respiratory distress scores, bronchodilator timing, transfer to higher care, and readmission rates.

Main Results:

• 377 doses of 3% saline were administered without bronchodilators.
• A low adverse event rate of 1.0% (95% CI: 0.3%-2.8%) was observed.
• One instance of bronchospasm (0.3%) was the only significant adverse event.

Conclusions:

• Nebulized 3% saline without adjunctive bronchodilators demonstrated a low adverse event profile in hospitalized infants with bronchiolitis.
• Further clinical trials are warranted to assess the efficacy of 3% saline in bronchiolitis when used independently of bronchodilators.
