What is Blue Baby Syndrome?

About Blue Baby Syndrome:

  • Blue baby syndrome, also called cyanosis, is a condition in babies in which their skin appears blue or purple tinged. 
  • What causes blue baby syndrome?
    • The baby takes on a bluish hue because of poorly oxygenated blood.
    • Normally, blood is pumped from the heart to the lungs, where it receives oxygen.
    • The blood is circulated back through the heart and then throughout the body.
    • When there’s a problem with the heart, lungs, or blood, blood may not be oxygenated properly.
    • This causes the skin to take on a blue color.
    • The lack of oxygenation can occur for several reasons.
  • It can occur due to several congenital (meaning present at birth) heart defects or environmental or genetic factors.
  • Acquired methemoglobinemia is more common than the congenital form. It can be caused by exposure to a variety of substances and by some health conditions.
  • The most common cause of blue baby syndrome is water contaminated with nitrates.
  • Symptoms:
    • The most common symptom of blue baby syndrome is a blue discoloration of the skin around the mouth, hands, and feet.
    • Other potential symptoms of blue baby syndrome include:
      • difficulty breathing
      • vomiting
      • diarrhea
      • lethargy
      • increased salivation
      • loss of consciousness
      • seizures
  • In severe cases, blue baby syndrome can even cause death.
  • Treatment:
    • Treatment will vary depending on what is causing the baby to turn blue.
    • If congenital heart disease is causing the discoloration, surgery may be required to correct the abnormalities.
    • Children with a more severe form of the condition may need a medication called methylene blue, which a doctor will give as an injection.
