Cyanosis in Newborns

A child comes into the world, and instead of the expected rosy cry, a bluish colouring appears on the lips, fingertips, sometimes across the entire body. The skin looks as if a cold film has been laid over it. The blood circulating through the small body does not carry enough oxygen. It flows, but it does not glow. It moves, but it does not breathe.

Medically, cyanosis in a newborn is an indication of oxygen undersupply — usually from a congenital heart defect in which oxygen-poor blood flows back into the systemic circulation without first having been routed through the lungs. Sometimes it is vascular malpositions, sometimes the lung itself, sometimes a combination. Acute medicine responds quickly: oxygen, stabilization, diagnostics, often an operation in the first days or months of life. That is right. That saves lives.
