Less invasive beractant administration in preterm infants: a pilot study.

Area of Science:

• Neonatal Medicine
• Pediatric Respiratory Care
• Medical Device Innovation

Background:

• Preterm infants (<32 weeks gestation) often require respiratory support.
• Surfactant replacement therapy is crucial for managing respiratory distress syndrome.
• Standard surfactant administration involves intubation, which carries risks.

Purpose of the Study:

• To assess the efficacy and feasibility of a novel, less invasive surfactant administration technique.
• To compare outcomes of this new method with standard treatment in preterm infants.
• To evaluate the use of a specifically designed cannula for beractant delivery.

Main Methods:

• A single-center, prospective, non-randomized pilot study.
• 30 preterm infants received less invasive surfactant administration (LISA) via cannula.
• A control group of 30 infants received standard treatment (intubation-surfactant-extubation).
• Beractant (4 ml/kg) was administered if FiO2 >30% was needed on nasal CPAP within 3 days.

Main Results:

• Successful beractant administration in all LISA patients.
• Significantly fewer LISA patients required invasive mechanical ventilation >1 hour (43.3% vs. 73%, p<0.036).
• No significant difference in invasive mechanical ventilation >48 hours or other outcomes between groups.

Conclusions:

• Less invasive surfactant administration with a dedicated cannula is feasible in preterm infants.
• This technique significantly reduces early exposure to invasive mechanical ventilation.
• The method offers a promising alternative to standard surfactant delivery strategies.
