Surfactant without intubation in preterm infants with respiratory distress: first multi-center data

Area of Science:

• Neonatal Medicine
• Respiratory Physiology
• Pediatric Critical Care

Background:

• A novel method for surfactant administration via a thin endotracheal catheter in spontaneously breathing, very low birth weight infants on nasal continuous positive airway pressure was previously reported.
• This study analyzes multicenter data to evaluate the efficacy of this new surfactant application method.

Purpose of the Study:

• To compare the clinical outcomes of very low birth weight infants treated with a new surfactant application method versus standard care.
• To assess the impact of the new method on the need for mechanical ventilation and rates of bronchopulmonary dysplasia.

Main Methods:

• A multicenter study prospectively collected data on infants with birth weight <1,500 g and gestational age <31 weeks.
• Infants receiving the new surfactant method (n=319) were compared to those receiving standard care (n=1,222).
• Outcomes included need for mechanical ventilation, bronchopulmonary dysplasia, and mortality.

Main Results:

• The new surfactant method group showed significantly lower rates of mechanical ventilation (29% vs. 53%, p<0.001) within 72 hours.
• Rates of bronchopulmonary dysplasia (10.9% vs. 17.5%, p=0.004) and death or bronchopulmonary dysplasia were significantly reduced in the treatment group.
• Medication usage differed, with more surfactant, theophyllin, caffeine, and doxapram, and less analgetics, catecholamines, and dexamethasone in the treatment group.

Conclusions:

• The new surfactant application method is associated with reduced mechanical ventilation and improved pulmonary outcomes in preterm infants.
• A prospective controlled trial is warranted to definitively establish the superiority of this novel approach compared to standard care.
