Abstract:Objective To study the effectiveness of different cleaning procedures and testing methods of rigid endoscope, so as
to seek the best cleaning and testing scheme. Methods A total of 300 rigid endoscopes contaminated by surgery in our hospital
were collected and randomly divided into the control group (60 sets) and the experimental group (240 sets). According to the
component materials, the rigid endoscopes were devided into non-immersible and immersible rigid endoscope. The experimental
group of immersible endoscope was divided into subgroups A, B, C and D according to different cleaning methods, with 60 sets
in each subgroup. The cleaning effect of all endoscope was detected with 10 times magnifying glass with light source, protein
detection rod and ATP bioluminescence detector. Results 10 times magnifying glass detection, protein residue detection and ATP
test showed that Subgroup D showed the highest qualification rate, which was obviously higher than the control group (P<0.05). For nonimmersible
rigid endoscope, protein residue detection and ATP test showed that the cleaning quality of the experimental group was
better than that of the control group (P<0.05). The efficiency of magnifying glass detection was lower that of protein residue detection
and ATP test (P<0.05). There was no significant difference between the efficacy of protein residue detection and ATP test (P>0.05),
with Kappa coefficient of 0.5839. Conclusion Non-immersible rigid endoscope should be pretreated with multi-enzyme
solution, and immersible rigid endoscope should be cleaned by ultrasonic spraying combined with automatic cleaning and
disinfection machine, which can greatly improve the qualified rate of cleaning. ATP bioluminescence test has high
reliability and convenience in evaluating the clean quality of rigid endoscope
