A prospective collection of positive antimicrobial cultures was performed over 12 consecutive months in the medical intensive care unit of a cancer hospital. In all, 144 infections and 163 pathogens were documented during 87 of the 528 admissions. Lung, urinary, ENT (ear, nose and throat) infections and bacteraemia were the most frequently documented. Staphylococcus species, Streptococcus species, Escherichia coli, Klebsiella species and Pseudomonas species were the most common pathogens. Gram-positive strains were observed predominantly during monomicrobial bacteraemia (48.9%). Methicillin-resistant Staphylococcus aureus (MRSA) and Staphylococcus epidermidis (MRSE) were found in 58% and 92% of the isolated strains respectively. No particular outbreak was identified. A further prospective study will be necessary to evaluate the impact of the antibiotic use on the selection of resistant strains in our ICU.

在癌症医院的医疗重症监护病房中连续12个月进行了阳性抗菌培养的前瞻性收集。在528的87例入院期间,共记录了144例感染和163例病原体。肺,泌尿,耳鼻喉科 (耳,鼻和喉) 感染和菌血症是最常见的记录。最常见的病原体是葡萄球菌,链球菌,大肠杆菌,克雷伯菌和假单胞菌。革兰氏阳性菌株主要在单株菌血症期间观察到 (48.9%)。分离株的58% 和92% 中分别发现了耐甲氧西林金黄色葡萄球菌 (MRSA) 和表皮葡萄球菌 (MRSE)。没有发现特别的爆发。需要进行进一步的前瞻性研究,以评估抗生素使用对我们ICU中耐药菌株选择的影响。
