Prompt
A 27-week gestation preterm infant, two hours old, is on nasal CPAP at 6 cm of water with grunting, retractions and an inspired oxygen that has climbed from 0.25 to 0.38; the candidate must recognise the surfactant threshold, decide on the technique and dose, set the oxygen target, and plan the prevention of bronchopulmonary dysplasia.

Candidate brief

You are the neonatal registrar called to review a 27-week gestation infant two hours after birth. The infant was born to a mother who received a full course of antenatal corticosteroids. The birth weight is 920 grams, the temperature is 36.8 degrees, and the infant is on nasal CPAP at 6 cm of water. The inspired oxygen has risen over the last hour from 0.25 to 0.38, with grunting, marked subcostal retractions and nasal flaring. The pre-ductal saturation is 92 percent at the current FiO2. A chest radiograph shows low lung volumes with fine granular opacities and air bronchograms. [1]
