SAQ 384 – Paediatrics – shocked cyanotic neonate with duct-dependent lesion

You are the emergency consultant responding to a paediatric resuscitation call. An 8-day-old infant arrives hypotonic, cyanotic, and peripherally cool. The infant remains centrally cyanosed with a poor peripheral saturation trace repeatedly reading 70%, is tachycardic, and has capillary refill of 5 seconds. While IV access and team organisation are underway, the ECG shown below is obtained. High-flow oxygen by face mask does not improve the recorded saturation or cyanosis, and you suspect a duct-dependent lesion.

Give six (6) causes of shock in a neonate.
