目的比较三种方法灭菌膀胱镜的效果。方法对膀胱镜分别采用20g/L戊二醛浸泡(方法 A)、环氧乙烷灭菌(方法 B)、压力蒸汽灭菌(方法 C)等三种方法进行灭菌,于灭菌前、后采样进行细菌培养、菌落计数,比较3种方法的灭菌效果。结果消毒前所有样本细菌培养阳性率为100%。消毒后,方法 A灭菌合格率为95%,方法 B、C灭菌合格率均为100%。结论浸泡法消毒效果受外界因素和人为因素影响大,易造成灭菌不合格或灭菌后再污染,环氧乙烷及压力蒸汽灭菌法均佳。
Objective To compare the efficacy of three methods of sterilizing cystoscopy. Methods The cystoscopes were sterilized with 20g / L glutaraldehyde (Method A), ethylene oxide sterilization (Method B) and pressure steam sterilization (Method C) respectively. Before sterilization, After sampling, bacterial culture and colony counting were performed to compare the sterilization effects of the three methods. Results The positive rate of bacterial culture of all samples before disinfection was 100%. After disinfection, method A sterilization pass rate of 95%, method B, C sterilization pass rate was 100%. Conclusion The soaking method disinfection effect is affected by external factors and human factors, easily lead to sterilization failure or re-contamination after sterilization, ethylene oxide and pressure steam sterilization method are good.
