• poor feeding.
• irritability.
• a high-pitched cry.
• lethargy (sleepiness)
• brief pauses in breathing (apnoea)
• their muscles becoming unusually floppy, like a rag doll.

How do you confirm kernicterus?

Kernicterus is most often diagnosed in babies. One test that may be used to check bilirubin levels is a light meter. A doctor or nurse will check your baby’s bilirubin levels by placing the light meter on your baby’s head.

What level of bilirubin causes kernicterus in newborn?

Kernicterus, or bilirubin encephalopathy, is bilirubin-induced neurological damage, which is most commonly seen in infants. It occurs when the unconjugated bilirubin (indirect bilirubin) levels cross 25 mg/dL in the blood from any event leading to decreased elimination and increased production of bilirubin.

How does kernicterus cause brain damage?

Kernicterus is a very rare type of brain damage that occurs in a newborn with severe jaundice. It happens when a substance in the blood, called bilirubin, builds up to very high levels and spreads into the brain tissues. This causes permanent brain damage.

What are the signs of bilirubin toxicity that leads to kernicterus?

Toxic levels of bilirubin may accumulate in the brain, potentially resulting in a variety of symptoms and physical findings. These symptoms may include lack of energy (lethargy), poor feeding habits, fever, and vomiting.

How does kernicterus cause cerebral palsy?

Jaundice can eventually lead to kernicterus, a type of brain damage from excess bilirubin that can lead to symptoms of cerebral palsy. Bilirubin can enter brain tissue from the bloodstream if it reaches too high of a level, resulting in damage to various areas of the brain.

How common is brain damage from jaundice?

In industrialized countries, only 0.4 to 2.7 of every 100, 000 children develop kernicterus or a condition called acute bilirubin encephalopathy. This is where bilirubin levels are so high they spread to the brain and damage the central nervous system tissues.

Is your baby at risk of kernicterus?

The bilirubin can damage the brain and spinal cord, which can be life threatening. Brain damage caused by high levels of bilirubin is also called bilirubin encephalopathy. Your baby may be at risk of developing kernicterus if: Kernicterus is now very rare in the UK, affecting less than 1 in every 100,000 babies.

What is kernicterus kernicterus?

Kernicterus Kernicterus is a rare but serious complication of untreated jaundice in babies. It’s caused by excess bilirubin damaging the brain or central nervous system.

What is kernicterus jaundice?

Kernicterus Newborn jaundice. In newborn babies with very high levels of bilirubin in the blood (hyperbilirubinaemia), the bilirubin can cross the thin layer of tissue that separates the brain and blood (the blood-brain barrier). The bilirubin can damage the brain and spinal cord, which can be life threatening.

Does bilirubin cause kernicterus?

Kernicterus Newborn jaundice. Brain damage caused by high levels of bilirubin is also called bilirubin encephalopathy. Your baby may be at risk of developing kernicterus if: they have a very high level of bilirubin in their blood the level of bilirubin in their blood is rising rapidly.
