1.皮肤面积 成人皮肤表面积约是新生儿的7倍,而成人体重却增加约20倍,使新生儿1kg体重的皮表面枳较成人大。以烧伤按皮肤损伤面积计算为例,小儿包括新生儿头部、颜面、大腿及小腿占全部皮表面积比例大是重要特征。 2.皮肤厚度 成人皮肤厚新生儿皮肤薄仅0.5mm,表皮最外层的皮质层薄,对物理化学刺激的抵抗能力差,容易受到损害。频繁的大便刺激可致新生儿肛周皮肤炎就是例证。皮下脂肪厚度从新生儿期至成人变化很大。新生儿皮下脂肪层厚的部位
1. Skin area Adult skin surface area is about 7 times that of newborns, while adult weight increased about 20 times, so that 1kg body weight neonatal skin trifoliate orange than adults. Taking burns calculated by area of skin injury as an example, it is an important feature that infants, including the proportion of newborn’s head, face, thighs and calves, account for the entire surface area of the skin. 2. Skin Thickness Adult skin thick thin neonatal skin is only 0.5mm, the outermost layer of the cortex of the epidermis thin, poor resistance to physical and chemical stimulation, vulnerable to damage. Frequent stool stimulation can cause neonatal perianal dermatitis is an example. Subcutaneous fat thickness varies greatly from newborn to adult. Neonatal subcutaneous fat layer thick parts
