Non-Invasive Surfactant Administration in Preterm Infants

Area of Science:

• Neonatal Medicine
• Respiratory Physiology
• Pediatric Pulmonology

Background:

• Traditional surfactant replacement therapy for respiratory distress syndrome (RDS) involves endotracheal intubation, posing risks of complications and bronchopulmonary dysplasia (BPD).
• Development of less invasive surfactant administration strategies is crucial to mitigate these risks in preterm infants.

Purpose of the Study:

• To review and evaluate current literature on less invasive surfactant delivery techniques for RDS in preterm infants.
• To assess the feasibility, efficacy, and short- and long-term neonatal outcomes of these techniques.

Main Methods:

• Literature review of less invasive surfactant administration methods: InSurE, Less Invasive Surfactant Therapy/Minimally Invasive Surfactant Therapy (LISA/MIST), surfactant administration via laryngeal mask airway (SALSA/LMA), pharyngeal administration, and nebulized surfactant.
• Comparison of key outcomes: mechanical ventilation rates, BPD incidence, procedural complications, and neurodevelopmental outcomes.

Main Results:

• Non-invasive surfactant administration is linked to reduced mechanical ventilation and lower BPD rates compared to conventional methods.
• LISA/MIST shows consistent benefits in reducing mechanical ventilation and BPD.
• Other techniques like LMA-assisted delivery and nebulization show potential but require further investigation due to device limitations and study heterogeneity.
• Long-term neurodevelopmental data are limited across all techniques.

Conclusions:

• Non-invasive surfactant administration is a significant advancement in RDS management.
• Further high-quality studies are needed to optimize patient selection, standardize techniques, and evaluate long-term neurodevelopmental effects.
• Development of safe and effective delivery devices is essential for widespread adoption.
