ABSTRACT
Objective:
To investigate the cleaning effects of biofilm cleaning agent and two kinds of multi-enzyme detergents on endoscopic biofilm.Methods:
Endoscopic biofilm model was established using pseudomonas aeruginosa, and soaked with No. 1 multi-enzyme detergent, No. 2 multi-enzyme detergent, and biofilm cleaning agent respectively. The control group was cleaned with sterile water. After 5, 10, and 15 minutes at room temperature, the cleaning effects were evaluated by bacteria counting method and scanning electron microscope. Arova was used for the comparison of viable counts among groups.Results:
At 5, 10, and 15 minutes of soak, the standard colony counts (CFU/cm 2) of biofilm was 5.31±0.10, 5.04±0.08 and 4.90±0.16 in the No.1 multi-enzyme detergent group, 5.53±0.30, 5.39±0.21 and 5.03±0.42 in the No.2 multi-enzyme detergent group, and 3.53±0.30, 3.01±0.07 and 2.82±0.26 in the biofilm cleaning agent group, and 7.92±0.21 in the blank control group. There was no significant difference in the colony counts between the two multi-enzyme detergent groups ( P>0.05). However, the colony counts of biofilm cleaning agent group was less than that of the two multi-enzyme detergent groups ( P<0.05), and decreased with time ( P<0.05). Under scanning electron microscope, the biofilm cleaning agent group had the least residual biofilm and bacteria.Conclusion:
Biofilm cleaning agent can significantly improve the quality of endoscopic cleaning, and is worthy of clinical promotion.
