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]
You have read the opening of this case. The complete unit — every section and its primary-source references — is part of the Paediatrics Fellowship fellowship atlas.
