Neonatal thrombocytopenic purpura

Thrombocytopenia is one of the main causes of neonatal bleeding, and the normal range of platelet counts in neonates and preterm infants is similar to that of other age children. Neonatal thrombocytopenic purpura is characterized by extensive skin petechiae, ecchymosis, and severe cases may include gastrointestinal bleeding and intracranial bleeding. It is generally believed that a platelet count of 100? 109 / L (100,000 / mm3) is thrombocytopenia, and some people think that less than 150? 109 / L (150,000 / mm3) is abnormal, and the cause should be found out. There are many causes of neonatal thrombocytopenia, the pathogenesis is more complicated, and the clinical manifestations are diverse.
