To determine the outcome of paediatric oncology patients with positive blood cultures.
Retrospective chart review.
Tertiary care hospital.
Oncology patients up to 17 years of age with positive blood cultures from January 1, 1994 to March 31, 1999.
There were 121 episodes of positive blood cultures in 76 patients. Seventeen episodes were excluded because blood cultures were contaminated. Of the organisms grown from the remaining episodes, 63% were Gram-positive organisms, 23% were Gram-negative organisms, 3% were fungal and 11% were mixed. There were 13 episodes with pure or mixed isolates of Staphylococcus aureus, of which nine occurred within 14 days of the placement of a new central venous tunnelled catheter. Central venous tunnelled catheters were retained in 76 of the 102 episodes when they were present. There were two relapses, and four children were admitted to the intensive care unit with septic shock, but all survived.
The outcome was excellent with the current management of possible bacteremia in paediatric oncology patients, but the high incidence of S aureus bacteremia suggests that empirical antibiotics should be altered if sepsis is suspected within 14 days of the placement of a central venous catheter.
确定血培养阳性的儿科肿瘤患者的治疗结果。
回顾性病历审查。
三级护理医院。
1994年1月1日至1999年3月31日期间血培养阳性的17岁及以下肿瘤患者。
76例患者出现121次血培养阳性。17次血培养因污染被排除。在其余血培养结果中生长的微生物,63%为革兰氏阳性菌,23%为革兰氏阴性菌,3%为真菌,11%为混合菌。有13次血培养分离出纯金黄色葡萄球菌或混合菌,其中9次发生在新的中心静脉隧道式导管置入后14天内。102次血培养中有76次存在中心静脉隧道式导管时予以保留。有2例复发,4名儿童因感染性休克入住重症监护病房,但均存活。
目前对儿科肿瘤患者可能发生的菌血症的治疗效果良好,但金黄色葡萄球菌菌血症的高发生率表明,如果在中心静脉导管置入后14天内怀疑有败血症,应更改经验性抗生素治疗方案。
