Pediatrics · Neonatology: less invasive surfactant

Sample item

A 30-week preterm on CPAP has increasing oxygen need and a chest radiograph showing ground-glass opacities. What is the preferred way of giving surfactant?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Less invasive surfactant administration while the infant stays on CPAP

CPAP is started first in preterm RDS, and surfactant is given if the oxygen requirement rises. Less invasive administration through a thin catheter avoids prolonged mechanical ventilation.

Option by option

  • A. Less invasive surfactant administration while the infant stays on CPAP (correct)

    Correct. LISA on CPAP is the preferred approach.

  • B. Routine prophylactic intubation in every infant

    Routine intubation increases ventilator-induced injury and is not needed for all.

  • C. Nebulised steroids

    Nebulised steroids do not replace surfactant.

  • D. Oral surfactant

    Surfactant must be delivered intratracheally.
