Introduction
The three main features of hemolytic anemia in newborns include jaundice, kernicterus, and splenomegaly. Jaundice is a typical characteristic, presenting as waxy yellow skin, pallor of the skin and mucous membranes, and pale conjunctiva. Severe anemia may lead to kernicterus, which manifests as motor impairments and hearing deficits, and in severe cases can result in cerebral palsy. Abnormalities in the hematopoietic system may cause splenomegaly or lymphadenopathy.
The three main features of hemolytic anemia in newborns include jaundice, kernicterus, and splenomegaly.
1. Jaundice
Hemolytic anemia primarily involves the destruction of red blood cells, with pathologic jaundice being a typical characteristic. It commonly presents as pallor of the skin and mucous membranes, pale conjunctiva, and a waxy yellow appearance of the newborn's skin. In its early stages, it can easily be confused with physiologic jaundice, so timely systematic evaluation is necessary.
2. Kernicterus
Severe anemia may lead to kernicterus, in which rapidly rising levels of serum bilirubin increase the risk of acute bilirubin encephalopathy. This typically manifests as motor dysfunction and hearing impairment. Without prompt and appropriate treatment, normal growth and development may be impaired, and in severe cases, it can result in cerebral palsy.
3. Splenomegaly
Hemolytic anemia can cause neonatal hypoxemia and predispose to compensatory cardiac arrhythmias. Abnormalities in the hematopoietic system may lead to splenomegaly or lymphadenopathy, posing a serious threat to health. It is important to promptly bring the newborn to a qualified medical facility for relevant examinations and, under the guidance of a specialist, initiate systematic treatment based on the specific condition.
