中文摘要 | Acinetobacter baumannii 所造成的感染日益增加,已成為重要院內感染致病菌,且對多種抗生素容易產生抗藥性的特性是值得憂心的。近年來,多重抗藥性A. baumannii菌株造成的院內感染屢有報告,常造成加護中心低免疫力病患的感染群突發。我們回溯研究由 1997 年至 1999 年某醫學中心的住院病患 A. baumannii的院內感染,分析其在普通病房與加護中心的感染率、感染部位及危險因子。結果發現加護中心的感染發生密度為普通病房的 18 倍。再者,呼吸道感染在加護中心最常見;然而在普通病房則以血流感染及呼吸道感染最為常見。呼吸道感染可能與被污染的環境及呼吸治療裝置有關;而血流感染則是與血管內導管感染最有相關,可藉由醫護人員雙手作為傳播途徑。總之,在高危險單位嚴格推行洗手及接觸隔離政策,實施侵入性醫療措施之流程標準化,儘早移除不必要的侵入性導管,以及適當的抗生素使用,為控制 A. baumannii院內感染的最好方法。(感控雜誌2001;11:216-26) |
英文摘要 | The natural resistance to several antibiotics and the ability to acquire resistance factors have rendered the A. baumannii an increasingly important nosocomial pathogen. Outbreaks occur frequently in the intensive care units and may iiivolve a large number of patients. Most of these acquire respiratory tract and blood stream infections. We retrospectively analyzed A. baumannii nosocomial infections at a medical center over a 3-year period from January, 1997 till December, 1999. The infection rates, sites of infections and the predisposing factors of infections in ICUs and non-ICU wards were examined. The incidence density of the infections in ICUs was higher than that of non- ICU wards (18:1). Respiratory tract infections caused by A. baumannii were most common in ICUs while the bloodstream infection was most frequently seen in the wards. Nosocomial respiratory tract infections have been correlated to contaminated ventilation equipment, and blood stream infections to the infected intravenous catheters. The usual mode of transmission is via the hands of hospital personnel. Keys to the successful control of A. baumannii nosocomial infections are frequent handwashing, early removal of intravascular catheters, strict adherence to aseptic techniques during any invasive procedures, and the judicious use of antibiotics for high risk patients.
