Question

An infant born at 29 weeks is intubated and receiving MV support. The infant failed to respond to surfactant therapy. Which of the following best describes the timing of the second dose of surfactant?

a) Immediately after the first dose
b) After 6 hours
c) After 12 hours
d) After 24 hours

Answer 1

The second dose of surfactant for an infant born at 29 weeks who hasn't responded to the first dose is typically administered after 12 hours.

Step-by-step explanation:

The timing of the second dose of surfactant for an infant born at 29 weeks and not responding to the first dose would typically depend on the specific treatment protocol followed by the medical team. However, a common approach is to administer the second dose of surfactant after 12 hours.

Pulmonary surfactant is critical for inflation of the lungs, as it reduces surface tension. In preterm infants, who may not have sufficient surfactant production, additional doses of surfactant may be administered to improve respiratory function.

It's important to note that the exact timing of the second dose may vary depending on the infant's condition and the judgment of the medical team.
