A newborn was noted to be cyanotic. Unfortunately the imaging facilities are unavailable for the day. A hyperoxia test was thus done which showed no improvement of PaO2 after administration of 100% O2. The next step in the management of this neonate is:
A. Low tidal volume mechanical ventilation B. Positive pressure ventilation
C. Digoxin
D. Emergency tracheostomy
E. Prostaglandin E
E. Prostaglandin E
The hyperoxia test is used to differentiate whether the etiology of cyanosis is cardiac or not. PaO2 does not improve in cardiac etiologies.
In the absence of imaging for definitive diagnosis of the congenital heart disease, the clinician should not hesistate to administer prostaglandin in case the patient has a ductus dependent congenital heart disease. Prostaglandin prevents the ductus from closing.

A. Ductus venosus
B. Ductus arteriosus
C. Left umbilical vein
D. Right umbilical vein
E. Umbilical artery

The ductus venosus forms the ligamentum venosum; the ductus arteriosus forms the ligamentum arteriosum; the umbilical artery forms the medial umbilical
ligament.
