【摘要】：目的比较1.5%、3%过氧化氢、酸性氧化电位水和无菌生理盐水漂洗方法对医用塑料气管内套管的消毒效果。方法分别采用上述方法对气管切开患者使用中的气管内套管进行清洗消毒,对每种方法清洗消毒前后、4种方法清洗消毒前、后内套管的菌落数进行比较。结果 4种方法清洗消毒前内套管的染菌量均较严重,为10 565~11 150CFU/ml,各组间比较,差异无统计学意义;每种方法清洗消毒前后内套管菌落数比较,差异有统计学意义(P0.01);4种方法清洗消毒后内套管的菌落数比较,只用无菌生理盐水漂洗组3 850CFU/ml与其他各组1 225~2 285CFU/ml,差异均有统计学意义(P0.001);其余各组间差异均无统计学意义。结论过氧化氢和酸性氧化电位水对减少气管内套管的菌落数效果显著,无菌生理盐水漂洗组可减少菌落数,但无消毒作用,本试验结果建议目前选用3%过氧化氢作为医用塑料气管内套管的消毒液为佳,理想消毒方法有待进一步探讨。
[Abstract]:Objective to compare the disinfection effect of 1.5% hydrogen peroxide, acid oxidizing potential water and sterile saline on medical plastic trachea cannula. Methods the trachea cannula in tracheotomy patients was cleaned and disinfected by the above methods, and the bacterial colony number of each method before and after cleaning and disinfection was compared. Results the amount of bacterial contamination in the casing before cleaning and disinfecting by the four methods was serious, which was 10 565% 11 150 CFU / ml, there was no significant difference among the four groups, and the number of bacterial colonies in the casing before and after cleaning and disinfecting by each method was higher than that of the control group. The difference was statistically significant (P0.01). There were significant differences in the number of bacteria in the tube after cleaning and disinfecting (P0.01), and there was no significant difference between the other groups (P0. 001) and the other groups (P 0. 001). The bacterial colonies in the rinsing group with only sterile saline for 3 850CFU/ml were significantly higher than those in the other groups (P 0. 001). Conclusion hydrogen peroxide and acid oxidizing potential water can reduce the number of bacteria in trachea cannula significantly. The bacterial colony number can be reduced in the sterile saline rinsing group, but it has no disinfection effect. The results suggested that 3% hydrogen peroxide should be used as the best disinfectant for medical plastic trachea tube, and the ideal disinfection method should be further explored.
