Basics

Description

  • Aberrant embryonic development results in mixing of deoxygenated and oxygenated blood returning to systemic circulation by 2 mechanisms:

    • Right-to-left intracardiac shunt

    • Anatomic defec...

Diagnosis

  • Most common initial ED presentations of cyanotic congenital heart disease (CHD):

    • Cyanosis

    • CHF

    • Circulatory collapse

  • Physiologic stress triggers cyanosis in older patients with CHD:

    • Cardiac shunt o...

Treatment

Initial Stabilization/Therapy

  • Maintain warmth (cold ↑ O2 consumption).

  • Treat hypoglycemia and acidosis.

  • Maintain oxygenation.

  • Establish IV access.

  • Prepare for endotracheal intubation.

  • High oxygen ...

Follow-Up

Disposition

Admission Criteria

  • All newborns with suspected CHD:

    • Admit to pediatric ICU.

  • CHD with symptomatic pneumonia or respiratory syncytial virus

Discharge Criteria

Pearls and Pitfalls

  • Visual appearance of cyanosis requires >3–5 mg/dL deoxygenated hemoglobin.

  • Duct-dependent lesions:

    • Present at 2–3 wk of age

    • Sudden cyanosis or cardiovascular collapse

    • Treat with PGE...
