Neonatal Jaundice free essay sample

Newborn jaundice Newborn jaundice is a condition marked by high levels of bilirubin in the blood. The increased bilirubin causes the infants skin and whites of the eyes (sclera) to look yellow. Causes Bilirubin is a yellow pigment that is created in the body during the normal recycling of old red blood cells. The liver helps break down bilirubin so that it can be removed from the body in the stool. Before birth, the placenta the organ that nourishes the developing baby removes the bilirubin from the infant so that it can be processed by the mothers liver. Immediately after birth, the babys own liver begins to take over the job, but this can take time. Therefore, bilirubin levels in an infant are normally a little higher after birth. High levels of bilirubin in the body can cause the skin to look yellow. This is called jaundice. Jaundice is present to some degree in most newborns, and is called physiological jaundice.

Physiological jaundice usually causes no problems. Other types of jaundice that usually cause no harm include: Breast milk jaundice is probably caused by factors in the breast milk that slow the rate at which the liver breaks down bilirubin. Such jaundice appears in some healthy, breastfed babies after day 7 of life, and usually peaks during weeks 2 and 3. It may last at low levels for a month or more. Breastfeeding jaundice is seen in breastfed babies in the first week of life, especially in babies who are not nursing often enough. Breastfeeding jaundice is different than breast milk jaundice. Babies who are born too early (premature) are more likely to develop jaundice than full-term babies. Conditions that increase the number of red blood cells that need to be broken down, and can cause more severe newborn jaundice: Abnormal blood cell shapes Blood type mismatch between the mother and the baby Bleeding underneath the scalp (cephalohematoma) caused by a difficult delivery Higher levels of red blood cells, which is more common in small-for-gestational-age babies and some twins Infection Lack (deficiency) of certain important enzymes Conditions that make it harder for the babys body to remove bilirubin may also lead to more severe jaundice: Certain medications Congenital infections, such as rubella, syphilis, and others Diseases that affect the liver or biliary tract, such as cystic fibrosis or hepatitis Hypoxia Infections (such as sepsis) Many different genetic or inherited disorders Symptoms The main symptom is a yellow color of the skin. The yellow color is best seen right after gently pressing a finger onto the skin. The color sometimes begins on the face and then moves down to the chest, belly area, legs, and soles of the feet. Sometimes, infants with significant jaundice have extreme tiredness and poor feeding. Exams and Tests Doctors, nurses, and family members will watch for signs of jaundice at the hospital, and after the newborn goes home. Any infant who appears jaundiced should have bilirubin levels measured right away. This can be done with a blood test. Many hospitals check total bilirubin levels on all babies at about 24 hours of age. Hospitals use probes that can estimate the bilirubin level just by touching the skin. High readings need to be confirmed with blood tests. Tests that will likely be done include: Complete blood count Coombs test Reticulocyte count Further testing may be needed for babies who need treatment or whose total bilirubin levels are rising more quickly than expected. Treatment Treatment is usually not needed. When determining treatment, the doctor must consider: The babys bilirubin level How fast the level has been rising Whether the baby was born early (babies born early are more likely to be treated at lower bilirubin levels) How old the baby is now Your child will need treatment if the bilirubin level is too high or is rising too quickly. Keep the baby well hydrated with breast milk or formula. Frequent feedings (up to 12 times a day) encourage frequent bowel movements, which help remove bilirubin through the stools. Ask your doctor before giving your newborn extra formula. Some newborns need to be treated before they leave the hospital. Others may need to go back to the hospital when they are a few days old. Treatment in the hospital usually lasts 1 to 2 days. Sometimes special blue lights are used on infants whose levels are very high. This is called phototherapy. These lights work by helping to break down bilirubin in the skin. The infant is placed under artificial light in a warm, enclosed bed to maintain constant temperature. The baby will wear only a diaper and special eye shades to protect the eyes. The American Academy of Pediatrics recommends that breastfeeding be continued through phototherapy, if possible. Rarely, the baby may have an intravenous (IV) line to deliver fluids. If the bilirubin level is not too high or is not rising quickly, you can do phototherapy at home with a fiberoptic blanket, which has tiny bright lights in it. You may also use a bed that shines light up from the mattress. You must keep the light therapy on your childs skin and feed your child every 2 to 3 hours (10 to 12 times a day). A nurse will come to your home to teach you how to use the blanket or bed, and to check on your child. The nurse will return daily to check your childs weight, feedings, skin, and bilirubin levels. You will be asked to count the number of wet and dirty diapers. In the most severe cases of jaundice, an exchange transfusion is required. In this procedure, the babys blood is replaced with fresh blood. Treating severely jaundiced babies with intravenous immunoglobulin may also be very effective at reducing bilirubin levels. Outlook (Prognosis) Usually newborn jaundice is not harmful. For most babies, jaundice usually gets better without treatment within 1 to 2 weeks. Very high levels of bilirubin can damage the brain. This is called kernicterus. However, the condition is almost always diagnosed before levels become high enough to cause this damage. For babies who need treatment, the treatment is usually effective. Possible Complications Rare, but serious, complications from high bilirubin levels include: Cerebral palsy Deafness Kernicterus brain damage from very high bilirubin levels When to Contact a Medical Professional All babies should be seen by a health care provider in the first 5 days of life to check for jaundice. Those who spend less than 24 hours in a hospital should be seen by age 72 hours. Infants sent home between 24 and 48 hours should be seen again by age 96 hours. Infants sent home between 48 and 72 hours should be seen again by age 120 hours. Jaundice is an emergency if the baby has a fever, has become listless, or is not feeding well. Jaundice may be dangerous in high-risk newborns. Jaundice is generally NOT dangerous in term, otherwise healthy newborns. Call the infants health care provider if: Jaundice is severe (the skin is bright yellow) Jaundice continues to increase after the newborn visit, lasts longer than 2 weeks, or other symptoms develop The feet, especially the soles, are yellow Prevention In newborns, some degree of jaundice is normal and probably not preventable. The risk of significant jaundice can often be reduced by feeding babies at least 8 to 12 times a day for the first several days and by carefully identifying infants at highest risk. All pregnant women should be tested for blood type and unusual antibodies. If the mother is Rh negative, follow-up testing on the infants cord is recommended. This may also be done if the mothers blood type is O+, but it is not needed if careful monitoring takes place. Careful monitoring of all babies during the first 5 days of life can prevent most complications of jaundice. Ideally, this includes: Considering a babys risk for jaundice Checking bilirubin level in the first day or so Scheduling at least one follow-up visit the first week of life for babies sent home from the hospital in 72 hours Alternative Names Jaundice of the newborn; Neonatal hyperbilirubinemia; Bili lights jaundice References American Academy of Pediatrics (AAP). Management of hyperbilirubinemia in the newborn infant 35 or more weeks of gestation.
