目的探讨肿瘤患儿化疗相关感染早期临床表现与感染严重程度的关系,寻找早期提示重症感染的线索。方法 2005年10月至2009年1月在中山大学附属第一医院儿科化疗并发生化疗相关感染的肿瘤患儿136例,共发生感染346例次,比较重症感染与轻症感染患儿早期临床表现的差异。结果重症感染133例次,轻症感染213例次。重症感染患儿早期伴畏寒、寒战、精神欠佳、末梢循环不良、粒细胞缺乏的患儿明显多于轻症感染患儿,且热峰及发热6～12hC-反应蛋白(CRP)值均较轻症感染患儿高;接受强化疗患儿中,感染早期伴畏寒、寒战、精神欠佳、末梢循环不良、中性粒细胞计数≤0.5×109/L、CRP≥40mg/L、热峰≥39.5℃的患儿发生重症感染的机会大于无上述表现者,差异有统计学意义(P<0.05)。结论接受强化疗及感染早期伴畏寒、寒战、精神欠佳、末梢循环不良、中性粒细胞计数≤0.5×109/L、CRP≥40mg/L、热峰≥39.5℃患儿易发展为重症感染。

relation between early manifestations and severity of chemotherapy-related infection in children with tumor

Objective To discuss the relation between early manifestations and severity of chemotherapy-related infection in children with tumor. Methods The manifestations of infection during or after chemotherapy in 346 cases of 136 children with tumor were analyzed,and the differences in early manifestations between severe and mild infection were compared. Results One hundred and thirty-three cases had severe infection,and 213 cases had mild infection. The incidences of chill,ague,fatigue,poor peripheral circulation...
