纤维支气管镜活检钳两种消毒灭菌效果的比较

目的 探讨纤维支气管镜活检钳的消毒灭菌方法.方法 对环氧乙烷灭菌法和2％碱性戊二醛浸泡灭菌法两种纤维支气管镜活检钳灭菌方法进行比较.结果 两种方法灭菌后活检钳均未检出细菌,合格率为100.0％,均达到灭菌效果；2％碱性戊二醛浸泡灭菌后的活检钳在取用和使用时污染率为30.00％,独立纸塑包装低温环氧乙烷灭菌未发生污染,两者比较差异有统计学意义(x2=11.3,P＜0.05).结论 纤维支气管镜活检钳应首选独立纸塑包装低温环氧乙烷灭菌法灭菌；对于未配备环氧乙烷灭菌器且活检钳不耐高温则可选用2％碱性戊二醛浸泡灭菌法.

Effects of two methods of disinfection and sterilization for biopsy forceps of bronchofiberscope:a comparative study

OBJECTIVE To explore the methods of disinfection and sterilization for the biopsy forceps of bronchofiberscope.METHODS The ethylene oxide sterilization method and 2% of alkaline glutaraldehyde sterilization method for disinfection and sterilization of the biopsy forceps of bronchofiberscope were compared.RESULTS The bacterial colony counts in the biopsy forceps was 0 CFU perpiece,and the qualified rate was 100.0%,both achieved the sterilization effect;the incidence of contamination of biopsy forceps which were sterilized by 2% alkaline glutaraldehyde was 30.00%,and the incidence of contamination of biopsy forceps which were sterilized by independent plastic package low temperature ethylene oxide was 0,the difference was statistically significant(χ2=11.3,P<0.05).CONCLUSION The independent plastic package low temperature ethylene oxide should be considered as the first priority for sterilization for the biopsy forceps of bronchofiberscope;for the bronchofiberscope not equipped with ethylene oxide sterilizer and the biopsy forceps not adapting to high temperature,2% of alkaline glutaraldehyde sterilization method can be selected.
