目的探讨既往健康儿童社区获得性铜绿假单胞菌败血症的临床特点。方法对深圳市儿童医院2007—2008年出院诊断铜绿假单胞菌败血症的患儿资料进行回顾性分析。结果符合社区获得性铜绿假单胞菌败血症诊断标准、既往健康10例患儿,均<1岁,发病时间集中在每年4～10月。常见症状有发热、精神反应差、纳差、腹胀、腹泻、皮疹、呼吸急促。常见并发症为感染性休克、多器官功能障碍、弥漫性血管内凝血(DIC)。病程中多数患儿外周血白细胞降低,伴不同程度贫血。患儿C-反应蛋白(CRP)均显著增高,其中6例>100mg/L。细菌血培养阳性标本19份,均对哌拉西林/他唑巴坦、左旋氧氟沙星、丁胺卡那霉素、亚胺培南、氨曲南敏感,其他耐药率较低的药物依次为头孢吡肟、庆大霉素、环丙沙星、妥布霉素、头孢他啶。4例患儿入院时未选用敏感抗生素治疗,3例死亡,其中2例死于感染性休克、DIC(1例合并肺出血),1例死于肾功能衰竭。结论社区获得性铜绿假单胞菌败血症小婴儿多见,起病急,夏季发病,病死率高,并发症多。对于发热、精神反应差、有腹泻病史、病情进展迅速、早期出现感染性休克、外周血白细胞降低,特别是CRP显著增高的患儿均应考虑到本病的可能,并早期经验性使用...
