Surfactant therapy significantly reduces risks for premature infants with respiratory distress syndrome (RDS). Early or prophylactic treatment with natural surfactant extracts offers the best outcomes, though optimal usage is still debated.

Area of Science:

  • Neonatal Medicine
  • Pulmonology
  • Pharmacology

Background:

  • Respiratory distress syndrome (RDS) is a major cause of mortality in premature infants.
  • Surfactant therapy is a cornerstone in managing RDS, with over 50% of very low birth weight infants receiving it.
  • Despite widespread use, optimal surfactant administration strategies require further clarification.

Purpose of the Study:

  • To review current evidence on surfactant therapy for respiratory distress syndrome in premature infants.
  • To evaluate optimal dosage, timing, and method of surfactant administration.
  • To compare the efficacy of natural surfactant extracts versus synthetic preparations.

Main Methods:

  • Analysis of data from over 6,000 infants in randomized controlled trials.

  • Evaluation of studies comparing prophylactic versus early treatment strategies.
  • Comparison of different surfactant preparations (natural extracts vs. synthetic) and administration methods (bolus vs. infusion).

    • Main Results:

    • Both prophylactic and early surfactant administration reduce pneumothorax and mortality risks.
    • Initial doses of 100-200 mg/kg with repeat doses for relapsed infants appear optimal.
    • Natural surfactant extracts show a slight advantage over synthetic preparations in improving initial ventilatory status and reducing pneumothorax.

    Conclusions:

    • Surfactant replacement therapy is effective for very low birth weight infants with RDS.
    • Early treatment, either prophylactic or as soon as RDS signs appear, is supported.
    • Natural surfactant extracts demonstrate superior clinical outcomes compared to synthetic options.
