脉动式高压真空灭菌器具有消毒容量大、操作时间短、灭菌效果好等优点而逐渐代替了下排式高压灭菌锅。我院自1999年 1月完全采用该法灭菌以来 ,发现导尿包内的石蜡油棉签常常被吸出小瓶变干 ,临床导尿时需要重新注入灭菌石蜡油 ,不但使临床操作复杂化 ,也增加了导尿病人的感染? The pulsating high-pressure vacuum sterilizer gradually replaced the lower-row autoclave because of its advantages such as large disinfection capacity, short operation time, and good sterilization effect. Since our hospital completely sterilized by this method in January 1999, it has been found that the paraffin oil swabs inside the catheterization kit are often sucked out of the vial to dry out, and the clinical paraffin injection needs to be reinjected with sterile paraffin oil, which not only complicates the clinical operation. Has also increased catheter infection?
