分析 16例新生儿红细胞增症的临床和血液粘滞度 ,以及血液粘滞度与器官损害的关系。结果显示 :病因主要是围产期窒息 ;常见的合并症为高胆红素血症、新生儿缺氧缺血性脑病、心肌损害。全部病例血粘滞度均高 ,合并脑、心等器官损害病例的全血粘滞度较未发生损害病例明显升高 ,说明器官损害与高粘滞度有密切关系 ;少量分次部分换血治疗本病安全有效 ;决定部分换血时应考虑血红蛋白、红细胞压积 ,也应考虑血液的粘滞度 The clinical and blood viscosity of 16 neonates with erythrocytosis and the relationship between blood viscosity and organ damage were analyzed. The results showed that: the main cause of perinatal asphyxia; common complications of hyperbilirubinemia, neonatal hypoxic-ischemic encephalopathy, myocardial damage. All cases of blood viscosity were high, combined with brain, heart and other organ damage in patients with whole blood viscosity was significantly higher than the damage did not occur, indicating that organ damage and high viscosity are closely related to a small amount of fractional transfusion therapy The disease is safe and effective; part of the decision to change hemoglobin hemoglobin, hematocrit, blood viscosity should also be considered
