新生儿败血症的症状多无特异性,早期诊断较困难,临床工作者多根据临床表现应用抗生素直到血培养阴性才停药,有许多用药实际上是不需要的。如何使抗生素应用限制到最小范围,缩短住院时间,减少产生耐药菌株,对败血症的早期诊断成了儿科临床医学中存在的主要问题之一。近年来国外学者对早期快速诊断:感染的实验室检查进行许多研究,除血培养以外可分为非特异性和特异性二大类实验室诊断方法。 Neonatal sepsis symptoms are more specific, early diagnosis is more difficult, clinicians often based on clinical manifestations of antibiotics until blood culture was negative until the withdrawal of a lot of medication is actually not needed. How to limit the application of antibiotics to a minimum, shorten the length of hospital stay, and reduce the generation of drug-resistant strains. The early diagnosis of sepsis has become one of the major problems in pediatric clinical medicine. In recent years, foreign scholars have conducted many researches on early rapid diagnosis: laboratory tests of infection, and can be divided into two categories of non-specific and specific laboratory diagnostic methods besides blood culture.
