Neonatal polycythaemia has multifactorial causes, and can be designated as active (increased foetal erythropoiesis) or passive (red blood cell transfusion) polycythaemia. Hematocrit estimated from capillary blood (regularly obtained through "heel sticks" in newborns) is normally the principal laboratory feature facility by which polycythaemia is recognszed. An unusually high proportion of haematocrit builds the risk of hyperviscosity, microcirculatory hypoperfusion, and in the long run multisystem organ dysfunction. A report enclosed in this short communication gives a brief review of neonatal polycythaemia, its causes, management and complications.
新生儿红细胞增多症有多种病因，可分为主动性（胎儿红细胞生成增加）或被动性（红细胞输血）红细胞增多症。通过毛细血管血（通常通过新生儿“足跟采血”获取）估算的血细胞比容通常是识别红细胞增多症的主要实验室指标。血细胞比容异常升高会增加血液高黏滞度、微循环灌注不足的风险，并最终导致多系统器官功能障碍。本简短通讯所附报告简要综述了新生儿红细胞增多症、其病因、治疗及并发症。
