Newborn Jaundice

Newborn Jaundice is not a disease but a common condition caused by the accumulation of a yellow pigment called bilirubin in the bloodstream. This occurs because a newborn's liver is often not yet mature enough to efficiently remove bilirubin from the body. As a result, the pigment settles in the skin and the whites of the eyes, giving them a yellowish appearance.

The Dangers of Excessive Jaundice

If bilirubin levels become too high, the pigment can enter the brain cells, leading to a serious neurological condition called Kernicterus. Symptoms include extreme lethargy, poor feeding, vomiting, a high-pitched cry, seizures, and respiratory distress. If not treated promptly, it can cause permanent brain damage or developmental disabilities.

Two Types of Newborn Jaundice

1. Physiological Jaundice (Natural): Typically appears after the first 24 hours of life and usually resolves on its own within 1–2 weeks in otherwise healthy infants.
2. Pathological Jaundice (Abnormal): This requires medical attention and can be caused by prematurity, inadequate breastfeeding, blood type incompatibility (ABO/Rh), G6PD deficiency, biliary atresia (blocked bile ducts), infections (sepsis), or hypothyroidism. It often appears within the first 24 hours or lasts longer than 2 weeks, and may be accompanied by other signs of illness like lethargy or poor feeding.

Diagnosis

Pediatricians diagnose jaundice through a physical examination, checking the color of the skin, eyes, and stool. If significant jaundice is suspected, a blood test is performed to measure the exact bilirubin levels. If the levels exceed the safety threshold for the infant's age, treatment will begin immediately.

Treatment Options

1. Phototherapy: The infant is placed under special high-intensity blue lights. This light changes the structure of the bilirubin molecules so they can be easily excreted through stool and urine. Note: Natural sunlight is not an effective or safe treatment for clinical jaundice.
2. Exchange Transfusion: This involves slowly replacing the infant's blood with fresh donor blood to rapidly lower bilirubin levels. This life-saving procedure is reserved for infants with dangerously high levels who do not respond to phototherapy or show signs of brain involvement.

Care and Prevention Guidelines

• Frequent Feeding: Ensure the baby breastfeeds or consumes formula at least 8–12 times every 24 hours. Frequent feeding promotes bowel movements, which help remove bilirubin. Do not give water, as it does not help remove bilirubin and may cause the baby to drink less milk.
• Monitor Daily: Check your baby's skin color at least once a day in natural light. A simple way to check is to gently press the skin on the baby’s abdomen or thigh with your finger. If the skin looks yellow when you lift your finger, consult a doctor.

Warning Signs: Seek Medical Attention Immediately If:

• The yellowish tint deepens rapidly or the whites of the eyes become noticeably yellow.
• The baby remains jaundiced after 1 week of age.
• The baby passes pale or clay-colored stools, or has dark-colored urine.
• Jaundice is accompanied by lethargy, refusal to feed, excessive sleepiness, stiff muscles, or seizures.
