Bronchoscopic surfactant administration in pediatric patients with persistent lobar atelectasis

Area of Science:

• Pediatric critical care medicine
• Pulmonology
• Bronchoscopy and interventional pulmonology

Background:

• Persistent lobar atelectasis in pediatric patients on mechanical ventilation impairs gas exchange and lung mechanics.
• Common causes include airway obstruction and surfactant deficiency, prolonging mechanical ventilation.
• Effective treatment strategies for pediatric atelectasis are crucial for improving patient outcomes.

Purpose of the Study:

• To evaluate the efficacy of bronchoscopic suctioning and surfactant administration in treating pediatric lobar atelectasis.
• To assess improvements in oxygenation, ventilation, chest X-ray scores, and time to extubation.
• To determine the safety and recurrence rates of this intervention.

Main Methods:

• A prospective study involving five pediatric patients (7 months to 15 years) with heterogeneous lung diseases and lobar atelectasis.
• Bronchoscopic instillation of a diluted surfactant preparation (Curosurf, 5-10 mg/ml, 120-240 mg total dose) into affected lung segments.
• Monitoring of gas exchange, respiratory rate, chest X-ray findings, and extubation status.

Main Results:

• All five mechanically ventilated patients were successfully extubated within 24 hours post-intervention.
• Bronchoscopic surfactant application was performed without adverse effects.
• Significant improvements were observed in oxygenation, respiratory rate, and radiographic resolution of atelectasis.
• No recurrence of atelectasis was noted during the follow-up period.

Conclusions:

• Bronchoscopic surfactant application is a safe and effective treatment for pediatric lobar atelectasis.
• The procedure leads to rapid clinical improvement, including enhanced gas exchange and early extubation.
• This minimally invasive approach offers a promising therapeutic option for improving respiratory mechanics in critically ill children.
