纤维支气管镜活检钳两种消毒灭菌效果的比较

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

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(χ2=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。

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 effec;; 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 （x2 = 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 bronchofiber- scope; 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.
