To evaluate the practice of empiric antibiotics for febrile, nonneutropenic pediatric oncology patients with a central venous catheter (CVC) in place.
Episodes of fever without neutropenia (absolute neutrophil count [ANC] ≥500 cells/mm(3)) were reviewed retrospectively in pediatric oncology patients with a CVC undergoing chemotherapy. Characteristics and symptoms were compared between patients with bacteremia and patients without bacteremia.
A total of 392 episodes of nonneutropenic fever in 138 subjects (52 females; 38%) were reviewed. In this cohort, the median age at an episode was 7 years, and the majority of patients had a diagnosis of acute leukemia (54%). Median ANC was 3100 cells/mm(3) (IQR, 1570-5980 cells/mm(3)). Median temperature was 38.7°C (IQR, 38.3-39.2°C). Twenty-four infectious episodes (6%) occurred in 18 subjects, and 5 CVCs required removal; all patients requiring removal admitted and received antibiotics owing to chills. There were no significant difference in age, sex, or ANC between patients with bacteremia and those without bacteremia; however, mean temperature was higher in the patients with bacteremia (39.4°C vs 38.7°C; P = .003). No deaths due to sepsis occurred, and no CVCs were removed because antibiotics were not administered empirically.
Our practice of observing pediatric oncology patients undergoing chemotherapy with CVCs who are not neutropenic does not appear to lead to increased serious adverse outcomes and avoids antibiotic exposure for >90% of patients without a bacterial infection.
评估放置中心静脉导管(CVC)的发热性非中性粒细胞减少儿科肿瘤患者经验性使用抗生素的情况。
回顾性分析正在接受化疗的置管儿科肿瘤患者中性粒细胞减少(绝对中性粒细胞计数[ANC]≥500 个/立方毫米)的发热病例。比较菌血症患者和非菌血症患者的特征和症状。
共回顾了 138 例患者的 392 例非中性粒细胞减少性发热病例(52 例女性;38%)。该队列患者的中位年龄为 7 岁,大多数患者患有急性白血病(54%)。中位 ANC 为 3100 个/立方毫米(IQR,1570-5980 个/立方毫米)。中位体温为 38.7°C(IQR,38.3-39.2°C)。24 例感染性发热发生在 18 例患者中,5 例 CVC 需要移除;所有需要移除 CVC 的患者因寒战而住院并接受抗生素治疗。菌血症患者和非菌血症患者的年龄、性别或 ANC 无显著差异;然而,菌血症患者的平均体温较高(39.4°C 比 38.7°C;P=0.003)。没有因败血症死亡的病例,也没有因未经验性使用抗生素而移除 CVC。
我们对接受化疗且未发生中性粒细胞减少的置管儿科肿瘤患者进行观察的做法似乎并未导致严重不良后果增加,并避免了超过 90%无细菌感染患者暴露于抗生素。
