医院内获得性感染是指患儿在住院期间出现的或出院后不久发生的感染,其中不包括儿童在入院前已经开始或入院时已经处于潜伏期的感染。目前,医院内感染许多是由于在抢救病人时,如:气管插管、建立静脉通道的危重患儿,医院内获得性感染率均比较高。同时,医院内感染的致病菌多数是对抗生素耐药的菌株或者在患儿体内很快发为耐药性菌株,导致机体本身正常菌群发生紊乱。因此,研究医院内获得性感染在现代儿科疾病中的地位,采取积极有效地措施降低医院内获得性感染率具有重要的意义。
Infection in hospital refers to an infection that occurs in a child’s hospitalization or shortly after discharge, and does not include an infection in which the child has started or has been in an incubation period before admission. At present, many infections in hospitals are due to the relatively high rate of acquired infections in hospitals when rescue patients, such as tracheal intubation and the establishment of venous access in critically ill children. At the same time, the majority of pathogenic bacteria infected in the hospital are resistant to antibiotics or bacteria in children quickly sent to drug-resistant strains, leading to the body itself, the normal flora disorder. Therefore, it is of great significance to study the status of acquired infections in hospitals in modern pediatric diseases and to take active and effective measures to reduce the rate of acquired infections in hospitals.
