新生儿血液的红细胞多,血红蛋白高,血液粘度高,心脏搏动力又较弱,血流速度较缓,红细胞处于易聚集状态。上海第一医学院儿科医院用肢体血流图测定法,发现新生儿硬肿症的肢体血流量减少。他们又测定了红细胞表面电荷,发现新生儿硬肿时,红细胞表面电荷减少,红细胞相互排斥力降低,使红细胞易于聚集,再加上血液粘度增加,局部血流量减少,血流缓慢等因素导致微循环障碍、休克、DIC的发生。武汉市第五人民医院检测新生儿硬肿症甲皱壁微循环,找出其特征:①底色暗
Neonatal red blood cells and more blood, high hemoglobin, high blood viscosity, heart beat power and weaker, slower blood flow, erythrocytes in an easily aggregated state. Pediatric Hospital of Shanghai First Medical School with limb blood flow measurement, found that neonatal scleroderma limb blood flow decreased. They also measured the surface charge of erythrocytes. When neonatal sclerosis was found, the surface charge of erythrocytes decreased, the repulsion of erythrocytes decreased, and the erythrocytes were easy to accumulate. Coupled with the increase of blood viscosity, the decrease of local blood flow and the slow of blood flow, Circulation disorders, shock, the occurrence of DIC. Wuhan Fifth People’s Hospital detection of neonatal scleroderma microcirculation, to find out its characteristics: ① background color dark
