What are the causes of neonatal hypoglycemia?
Infants are at risk for more severe or prolonged hypoglycemia due to one or a combination of the following underlying mechanisms: insufficient glucose supply, with low glycogen or fat stores or poor mechanisms of glucose production; increased glucose utilization caused by excessive insulin production or increased …
What are the most common causes of pathologic hyperbilirubinemia in neonates?
Common risk factors for hyperbilirubinemia include fetal-maternal blood group incompatibility, prematurity, and a previously affected sibling (Table 1). Cephalohematomas, bruising, and trauma from instrumented delivery may increase the risk for serum bilirubin elevation.
What is kernicterus disease?
Kernicterus is a type of brain damage that can result from high levels of bilirubin in a baby’s blood. It can cause athetoid cerebral palsy and hearing loss. Kernicterus also causes problems with vision and teeth and sometimes can cause intellectual disabilities.
Why do newborns get hyperbilirubinemia?
A newborn’s immature liver often can’t remove bilirubin quickly enough, causing an excess of bilirubin. Jaundice due to these normal newborn conditions is called physiologic jaundice, and it typically appears on the second or third day of life.
Which of the following neonates would be most likely to develop hyperbilirubinemia?
Which newborns are at risk for hyperbilirubinemia? About 60% of full-term newborns get jaundice. So do 80% of premature babies. Babies born to mothers with diabetes or Rh disease are more likely to have this condition.
What part of the brain is affected by kernicterus?
Regions most commonly affected include the basal ganglia; hippocampus; geniculate bodies; and cranial nerve nuclei, such as the oculomotor, vestibular, and cochlear. The cerebellum can also be affected.
What are the signs of kernicterus?
Initial symptoms of kernicterus in babies include:
- poor feeding.
- irritability.
- a high-pitched cry.
- no startle reflex.
- lethargy (sleepiness)
- brief pauses in breathing (apnoea)
- their muscles becoming unusually floppy, like a rag doll.
What causes bronze baby syndrome?
Abstract. “Bronze baby” syndrome is a rare complication of phototherapy for neonatal jaundice occurring due to modified liver function, particularly cholestasis, of various origins. We report a case which occurred in a premature infant who developed a grey-brown coloration during phototherapy.
What is the difference between jaundice and hyperbilirubinemia?
Hyperbilirubinemia is a condition in which there is a build up of bilirubin in the blood, causing yellow discoloration of the eyes and skin, called jaundice. Low levels of bilirubin in the newborn is common and does not cause any trouble and will resolve on its own in the first week of life.
What is the most serious problem that can result when a newborn infant has high levels of unconjugated bilirubin?
High levels of bilirubin can travel to your baby’s brain. This can cause seizures and brain damage. This is called kernicterus.
What are the two types of hyperbilirubinemia?
Depending on the type of bilirubin present in plasma, hyperbilirubinemias can be classified as unconjugated or conjugated hyperbilirubinemia [14].
