摘要 目的分析C反应蛋白(CRP)、降钙素原(PCT)在小儿急性呼吸道感染病原学判断中的临床意义。方法收集急性呼吸道感染患儿的CRP、PCT检测结果,对其进行汇总分析。结果检测CRP 6 949例,以CRP>8 mg/L者为阳性,共1 806例,阳性率为25.99%,其中>100 mg/L 73例,占1.05%。PCT共检测2 831例,>0.05 ng/mL者1 190例,阳性率为42.03%,其中≥10 ng/mL者21例,占1.76%,>10 ng/mL者临床症状重,病原学检测提示多为严重细菌感染。结论 CRP、PCT均在早期判断小儿急性呼吸道感染是否为细菌感染和细菌感染的严重程度上有着快速实用的临床价值,可指导经验应用抗菌药物,有着重要的指导价值。
