Nebulised 3% Hypertonic Saline Versus 0.9% Saline for Treating Patients Hospitalized With Acute Bronchiolitis

• Status: Recruiting
• Trial end date: 2025-03-01
• Target enrollment: 0
• Participant gender: All

Summary

Bronchiolitis is an acute viral infection of the lower respiratory tract. It is most commonly caused by respiratory syncytial virus (RSV). Only supportive therapy, including suctioning nasal secretions, water-electrolyte balance maintenance, and oxygen supplementation when needed, is recommended. The inhalation of 3% hypertonic saline is not recommended in bronchiolitis management. However, a recently published meta-analysis revealed that the inhalation of hypertonic saline can reduce the risk of hospitalisation for outpatients with bronchiolitis, while resulting in a shorter length of hospital stay and reduced severity of respiratory distress for inpatients, although the evidence is of low certainty.

The aim of the study is to assess the efficacy of nebulised hypertonic saline for the treatment of children hospitalised with bronchiolitis.
