在医源性感染中,泌尿道是原发感染最经常受累的部位,约占40%。本文回顾性分析了儿科医源性尿路感染危险人群的特点、病程和结果。方法患者为1981年1月1日～1985年12月31日在维吉尼亚大学儿童医疗中心的新生儿重症监护病房(NICU)、儿童重症监护病房(PICU)、学龄前病房(PAW)、学龄期病房(SAW))和烧伤病房(BU)住院的患儿。诊断标准:导尿管或耻骨上穿刺尿培养菌落>10~5个/ml尿,且感染发生在入院≥48小时或原来尿检查无感染者。尿化学分析采用Ames Clini-Tek,离心沉淀后进行显微镜分析。尿培养用0.001ml口径环将标本接种于羊血和MacConkey琼脂培养
In iatrogenic infections, the urinary tract is the site most frequently affected by primary infection, accounting for about 40%. This paper retrospectively analyzed the characteristics, course and results of pediatric patients at risk of iatrogenic urinary tract infection. Methods Patients were enrolled in a NICU, PICU, PAW, Pre-Ward, and Pre-Ward from January 1, 1981 to December 31, 1985 at the University of Virginia Children’s Medical Center. School-age wards (SAW)) and burn wards (BU). Diagnostic criteria: urinary catheter or suprapubic puncture urinary culture colonies> 10 ~ 5 / ml urine, and the infection occurred in ≥ 48 hours of admission or the original urine examination without infection. Urine chemical analysis using Ames Clini-Tek, after centrifugation and microscopic analysis. Urine culture specimens were inoculated on sheep blood and MacConkey agar with 0.001 ml caliber rings
