Abo hemolytic jaundice is unlikely to enter the brain. There are two types of hemolytic jaundice, one is abo hemolytic jaundice and the other is Rh hemolytic jaundice, which mainly occurs in newborns. Generally speaking, the degree of hemolysis in newborn babies with abo hemolytic jaundice is relatively mild, because in addition to the surface of red blood cells with the corresponding blood group antigen, other tissues in the body also have the corresponding blood group antigen, so when the antibody from the mother’s body and the surface of red blood cells combined with the antigen, but also at the same time will be combined with the surface of the body of the other tissues of the antigen, so the severity of the hemolysis can be greatly reduced, generally Hemolytic encephalopathy does not occur. Most of the abo hemolytic jaundice can disappear in half a month, only need to timely blue light irradiation and drug treatment, the condition can be relieved. A small number of patients with more serious hemolysis will appear anemia or even nuclear jaundice that is bilirubin encephalopathy, which is the most serious consequences, need to be diagnosed and treated in the hospital.
