新生儿出血性疾患 新生儿多种凝血因子低于正常水平,如凝血酶元、第Ⅶ、Ⅸ、Ⅹ、、Ⅺ、Ⅻ因子。血小板数可正常,但其功能差。如给予维生素K,各种凝血因子可增高,但仍易出血。而加强护理,减少新生儿感染,可大大减少出血。可见出血原因并非单纯决定于凝血因子的降低。 Neonatal hemorrhagic disorders newborn a variety of clotting factor below the normal level, such as thrombin, Ⅶ, Ⅸ, Ⅹ, Ⅺ, Ⅻ factor. Platelet count can be normal, but its function is poor. If given vitamin K, various coagulation factors may be increased, but still easy to bleeding. And to strengthen care and reduce neonatal infection, can greatly reduce bleeding. Visible causes of bleeding is not simply determined by the reduction of clotting factors.
