新生儿的皮肤是有它的特点的,其角层很薄,基层发育得很好,表皮和真皮之间的基膜细软且易破,弹力纤维、结缔组织和肌肉纤维的发育较弱。皮脂腺机能自新生儿期开始活动。汗腺要在生后3—4个月才开始活动。这说明新生儿的皮肤容易损伤、浸润和感染。如果新生儿皮肤一旦感染,其发展也很快,能形成皮下坏疽,以致危及生命。这是由於新生儿抵抗力弱、吞噬能力不良和淋巴腺的反应性弱,细菌容易扩延到全身,感染灶周围没有形成细胞障壁的能力,病变有弥漫性蔓延的倾向所致,所以新生儿皮肤减染是一个重要的问题。但是皮肤感染必须有皮肤的损伤才能引起,因此,只要我们在工 The newborn’s skin has its own characteristics, the angle is very thin, the grass-roots well developed, between the epidermis and dermis of the basement membrane soft and easy to break, elastic fibers, connective tissue and muscle fiber development is weak. Sebaceous gland function since the beginning of activity. Sweat glands in 3-4 months after birth to start activities. This shows that the newborn’s skin is easily damaged, infiltrated and infected. If the newborn skin once infected, its rapid development, can form subcutaneous gangrene, life-threatening. This is due to the weak neonatal immunity, poor phagocytic capacity and lymphatic reactivity weak, the bacteria easily spread to the whole body, the infection around the stove does not form the cell barrier capacity, the tendency of diffuse spread of the disease, so the newborn Skin lightening is an important issue. However, skin infections must be skin damage can cause, so long as we are working
