近年来由于对高危婴儿尤其低体重儿的抢救及成活率不断提高,新生儿出血性问题的出现亦日益增多。今将临床常见有关问题的诊断及处理予以介绍。新生儿出血的分类:1.新生儿期生理性凝血因子缺乏。2.继发于各种疾病的暂时性凝血障碍。3.先天性凝血机制的缺陷。4.血小板质或量的异常,其中以前两种类型的出血在新生儿期最为常见。新生儿凝血特点:1.新生儿的止血过程或凝血机制与成人相同。同样由血管粘附功能及血管收缩,血小板止血功能,及血液凝固三方面完成。2.体内凝血因子均由胎儿自身合成,其性质与成人无差别。母体的各种可溶性凝血因子均不能经胎盘至胎儿体内。3.纤维
In recent years, due to the high-risk infants, especially low-weight children’s rescue and survival rate continues to rise, the emergence of neonatal bleeding problems are also increasing. This clinical diagnosis and treatment of common problems to be introduced. Newborn bleeding classification: 1. Neonatal physiological clotting factor deficiency. 2. secondary to various diseases, temporary coagulation disorders. 3. Congenital coagulation defects. 4. Thrombocytosis or volume abnormalities, of which the previous two types of bleeding are most common in the neonatal period. Neonatal coagulation characteristics: 1. Neonatal hemostasis process or coagulation mechanism and adults the same. Also by the vascular adhesion function and vasoconstriction, platelet hemostasis, and blood coagulation done in three areas. 2. In vivo coagulation factors are synthesized by the fetus itself, its nature and no difference in adults. The mother of a variety of soluble coagulation factors can not be through the placenta to the fetus. 3. Fiber
