MSFinals-4625
As a junior doctor on the neonatal ward, you are asked to assess a premature baby born at 34 weeks gestation who is experiencing respiratory distress. The delivery was uneventful. The baby’s vital signs are as follows:
– Heart rate: 180 bpm (normal range: 100-180 bpm)
– Oxygen saturation: 95% (normal range: ≥ 96%)
– Respiratory rate: 68/min (normal range: 25-65/min)
– Temperature: 36.9°C (normal range: 36.0°C-38.0°C)
The baby is currently receiving 2 liters of oxygen to maintain their oxygen saturation. Upon examination, you notice that the baby is not cyanotic, but there are subcostal recessions and respiratory grunts. There are no added breath sounds on auscultation, but bowel sounds can be heard in the right lung field.
What is the most likely cause of the baby’s symptoms?
