摘要 细菌感染性疾病在我国患病新生儿中仍然占相当比例 ,此类疾病的早期诊断和及时治疗对提高诊疗水平、降低新生儿病死率有重要意义。近年来 ,降钙素原 (PCT)被认为是诊断全身性细菌感染性疾病的重要标志物。目前研究发现 ,细菌感染后血中PCT出现早于C反应蛋白 ,而且它具有较C反应蛋白和白细胞计数等临床常用指标更高的敏感性和特异性 ;另外 ,它与感染严重程度有较好的相关性 ,可用于评价疗效和估计预后。血清PCT检测简便快捷 ,便于临床应用 ,更重要的是 ,在新生儿期它不受母体PCT水平高低和窒息缺氧损伤引起的急性炎症反应的影响 ,仅与新生儿自身细菌感染严重程度有关 ,对新生儿疾病诊断有特殊意义。
