![]() Will be jaundice all over and may appear a muddy yellow color. It may persist for more than 2 weeks in some conditions when the baby It is significant in the first 24 hours of life especially if That alter the usual process involved in bilirubin metabolism in the liver. Pathological jaundice refers to jaundice that arises from factors Other Factors which may increase Physiological Jaundice This type of jaundice is the consequence of immature liver enzymes and high red cell mass. It is generally a temporary condition that does not cause babies harm and does not require any treatment. It occurs because of physiological changes taking place during the transition from intrauterine to neonatal life. Jaundice - a yellow coloring of the skin and eyes - occurs in approximately 60 percent of full-term newborns. Physiological jaundice occurs in the first few days after birth and will have cleared by day 10. ![]() ![]() Original yellow deposits fade leaving dead neurons resulting in permanent brain injury. This staining is permanent, which is why high serum bilirubin levels are so dangerous. It is broken down to be excreted.īilirubin is a product of this last process and the accumulation in the blood causes yellow staining on the skin.īilirubin can cross the blood/brain barrier and stain the basal ganglia, hippocampus, cranial nerve nuclei, cerebellar nuclei, and inferior olivary nuclei. The Haem is an iron compound and so can’t be re-used. The globin is a protein that is re-used by the body. The hemoglobin is broken down into its two constituents: Haem and Globin. When a red blood cell reaches the end of its life, the reticuloendothelial system takes it out of circulation. Hemoglobin is contained in the red blood cells and its most important function is to carry oxygen to the tissues. Therefore causing Physiological jaundice.īilirubin is a product of hemoglobin breakdown. In the first week of life, the baby’s Hb will drop to about 11g/dl and this breakdown of the fetal RBCs may cause bilirubin to exceed the plasma carrying capacity of the blood. ![]() This is necessary during fetal life to facilitate oxygen-carrying capacity.Īs soon as the baby is born and able to breathe oxygen the high Hb level is not needed and starts to drop. Predisposing factors of Neonatal JaundiceĪ newborn baby has a hemoglobin (Hb) level of 18-19g/dl. In some babies, the liver might not be developed enough to. During pregnancy, the mother’s liver removes bilirubin for the baby, but after birth the baby’s liver must remove the bilirubin. Jaundice happens when a chemical called bilirubin builds up in the baby’s blood. The term Jaundice comes from the French word jaundice, which means yellow thus a jaundiced baby is one whose skin color appears yellow due to bilirubin.īilirubin level of more than 85 umol/l (5 mg/dL) manifests clinical jaundice in neonates whereas in adults a level of 34 umol/l (2 mg/dL) would look icteric. Jaundice is the yellow color seen in the skin of many newborns. Neonatal jaundice is a yellow discoloration of the skin and mucous membranes as a result of raised bilirubin levels occurring in the first 28 days of life. ![]()
