Prophylactic Use of Nebulized Hypertonic Saline in Mechanically Ventilated Children: A Randomized Blinded Pilot Study

Area of Science:

• Pediatric Critical Care Medicine
• Respiratory Therapy
• Pharmacology

Background:

• Mucolytic agents like nebulized hypertonic saline may aid airway clearance and reduce mechanical ventilation duration.
• However, prospective blinded studies evaluating their use in pediatric patients are limited.

Purpose of the Study:

• To investigate the efficacy of prophylactic nebulized hypertonic saline in improving airway clearance and shortening mechanical ventilation duration in children.

Main Methods:

• A prospective, blinded study involving children under 18 requiring mechanical ventilation.
• Participants received either nebulized hypertonic saline or placebo (0.9% saline) four times daily.
• The primary outcome measured was the duration of mechanical ventilation.

Main Results:

• Children treated with hypertonic saline experienced a significantly longer duration of mechanical ventilation (208.1 hours) compared to placebo (129.5 hours).
• After adjusting for positive end-expiratory pressure (PEEP), no significant difference in ventilation duration was observed.
• Mechanical ventilation parameters and new-onset wheezing rates did not differ significantly between the groups.

Conclusions:

• Prophylactic nebulized hypertonic saline administration did not improve clinically relevant outcomes, including the duration of mechanical ventilation, in pediatric patients.
• The incidence of wheezing following hypertonic saline treatment was low in this study population.
