摘要 目的分析围产期新生儿血清中的降钙素原(PCT)、超敏C反应蛋白(hs-CRP)、内毒素和外周血白细胞计数(WBC)水平,探讨各个指标在围产期新生儿感染性疾病辅助诊断的作用。方法选取2015年2月至2018年12月本院新生儿病房住院的围产期新生儿207例,根据感染情况分为感染组(确诊感染性疾病的围产期新生儿,n=102)和非感染组(确诊非感染性疾病的围产期新生儿,n=105)。分析两组患儿入院时或未经治疗时的第1次实验室检查资料,采用横断面分析两组血清中的降钙素原(PCT)、超敏C反应蛋白(hs-CRP)、内毒素和外周血白细胞计数(WBC)的阳性率。结果围产期新生儿感染时PCT、hs-CRP、内毒素和WBC均有所升高,敏感性PCT>hs-CRP>内毒素>WBC;特异性内毒素>PCT>WBC>hs-CRP。PCT的Kappa值>0.75,诊断标准高度一致性,明显优于其他3个指标。结论内毒素、WBC作为诊断围产期新生儿感染性疾病的实验室指标参考价值不大。hs-CRP、PCT是围产期新生儿感染性疾病的重要实验室指标。考虑PCT在新生儿出生后3天内生理性升高,本研究采取横断面分析存在不足,但对临床围产期新生儿感染实验室检查指标仍有指导意义。
