就皮肤科处置的感染而言,门诊就医的患者为多,其感染多发生于体表,只要感染病灶能局限于皮肤,一般都会收到很好的疗效。然而,在由于长期卧床老年患者的褥疮,IVH导管的插入部等导致MRS-A严重感染的情况下,皮肤作为细菌入侵机体的门户,便具有极重要的意义。因此,检查皮肤感染病灶以及非病灶部位金黄色葡萄球菌的耐药性变化,特别对于预防医院内感染来说是十分重要的。一、皮肤和金黄色葡萄球菌皮肤位于机体的最外层,它所具有的厚厚的角质层以及表面的脂肪膜、皮脂中含有的脂肪酸都能抵御细菌的侵入。甚至对那些比表皮葡萄球菌等常在菌具有更强致病力的细菌,皮肤也同样能阻碍其生长、繁殖。然而,只要皮肤有了微小的损伤,金黄色葡萄球菌就会入侵、生长。例如:特应性皮炎患者的病变处
As far as dermatological infections are concerned, there are many outpatients seeking medical treatment. Most of the infections occur on the surface of the body. As long as the infected lesion can be confined to the skin, good results are generally obtained. However, in the case of serious MRS-A infection due to bed sores in bed-ridden elderly patients, insertion of IVH catheters, and the like, the skin acts as a gateway to bacterial invasion into the body and is of great importance. Therefore, examining skin infections and non-focal Staphylococcus aureus drug resistance changes, especially for the prevention of nosocomial infections is very important. First, the skin and Staphylococcus aureus skin is located in the outermost layer of the body, it has a thick stratum corneum and the surface of the fat membrane, sebum contains fatty acids are resistant to bacterial invasion. Even for those bacteria that are more virulent than bacteria such as Staphylococcus epidermidis, the skin can also hinder their growth and reproduction. However, Staphylococcus aureus invades and grows as long as the skin is slightly damaged. For example: Atopic dermatitis in patients with lesions
