棉拭子采样法:在消毒灭菌处理后4h内进行。用浸有无菌盐水采样液的棉拭子1支,在5cm×5cm的标准灭菌规格板内横竖往返各涂抹5次,连续采样1-4个规格板面积,剪去手接触部分,将棉拭子放入装有10ml采样液的试管中送检。结果按公式计算。
2. 层流设备
2. laminar flow equipmentICU的防污染要求比较高,icu病房,因为在ICU中,09年 icu,各种继发性疾病常引起呼吸衰竭,净化血液,病人须紧急气管切开、紧急开胸等手术,也包括正常术后病人的复苏,因此,在现 代ICU病房设计时要考虑使用层流净化设施,减少感染机率。ICU内温度应维持在24±1.5℃;老年患者病房温度在25.5℃左右。Anti pollution requirements of ICU is relatively high, because in ICU,济宁icu, various secondary diseases often cause respiratory failure, the patient must emergency tracheotomy and emergency thoracotomy surgery, including the patient's normal po*toperative recovery, therefore, in the modern design of the ICU ward to consider when using the laminar flow purification facilities, reduce the risk of infection. The temperature in ICU should be maintained at 24 + 1.5; the temperature of the elderly patients in the ward is about 25.5.
