我国乙肝发病率在逐年增多，外科手术病人乙肝阳性率也有上升趋势。如果对乙肝阳性患者术后污染物不严格管理，很容易引起手术室内交叉感染。随意弃之还会产生社会公害。本文介绍采用四种消毒剂（环氧乙烷、过氧乙酸、含氟消毒剂、碘伏），对八种污染物（污染器械、可回收污染敷料、不耐热可回收物品、污染吸引器瓶、污染手术间、污染垃圾、污染拖把、工作人员的手及污染手术鞋）进行处理，可杜绝医源性污染。
The incidence of hepatitis B in China is increasing year by year, and the positive rate of hepatitis B in surgical patients also has an upward trend. If the hepatitis B-positive patients with postoperative contaminant is not strictly managed, it is easy to cause cross-infection in the operating room. Disposable will give rise to public nuisance. This article describes the use of four kinds of disinfectants (ethylene oxide, peracetic acid, fluoride disinfectants, iodine), eight kinds of pollutants (contaminated equipment, recyclable contaminated dressings, heat-resistant recyclable items, Bottles, contaminated operating rooms, contaminated garbage, polluting mops, staff’s hands and contaminated surgical shoes) to prevent iatrogenic contamination.
