摘要

Abstract

Objective

The present study investigates the application of three cleaning quality detection methods in the cleaning effect of endoscope.

Methods

From June to December 2023

840 lumens from the postoperative endoscopes in the operating room of the Seventh Medical Center of the PLA General Hospital were selected and randomly divided into groups A

and C

with 280 in each group. The cleaning quality was detected before pretreatment

after pretreatment

and after cleaning and disinfection. Group A carried out in-situ protein fluorescence detection

group B carried out visual inspection + the visual trail viewer detection

and Group C carried out a combination of the three detection methods.

Results

The pollution status of the three groups A

and C were not statistically significant before pretreatment (χ

=0.474

=0.789). After pretreatment

the cleaning status of groups A

and C was not statistically significant (χ

=0.204

=0.903). However

after cleaning and disinfection

there was a statistical difference in the qualified rate of cleaning among groups A

and C (χ

=15.777

0.001). Further comparison between the two groups revealed that there is no statistically significant difference in the cleaning qualification rate between group A and group B (χ

=0.207

=0.649

)

while statistically significant differences were found between group A and group C (χ

=11.293

=0.001)

and between group B and group C (χ

=8.723

=0.003).

Conclusion

A combination of visual inspection

visual trail viewer detection

and in-situ protein fluorescence detection effectively improves the cleaning effect of endoscope tubes.
