A Meta-Analysis of Cleaning Effect of Different Cleaning and Disinfection Methods on Rigid Endoscopic Instruments
Objective To evaluate the cleaning effectiveness of manual cleaning,ultrasonic cleaning,and fully automatic cleaning on rigid endoscopic instruments.Methods With the systematic search of the randomized controlled trial study on different cleaning and disinfection methods for rigid endoscopic instruments in PubMed,EMbase,the Cochrane Library,China Biology Medicine disc(CBM),China National Knowledge Network Database(CNKI),VIP database,WanFang database and other Chinese and English databases,the deadline was February 2024,and the meta-analysis was conducted using RevMan5.4 software.Results Finally,8 literatures were included.Meta results showed that the qualification rate with ultrasonic cleaning of rigid endoscopic instruments was superior to manual methods in visual inspection,with statistical significance(RR=1.13,95%CI:1.02-1.26,P=0.02);The rigid endoscopic instruments cleaned by ultrasound were superior to manual cleaning in occult blood test,with statistical significance(RR=1.27,95%CI:1.11～1.46,P=0.0005);The rigid endoscopic instruments cleaned by ultrasound were superior to manual cleaning in ATP bioluminescence detection,with statistical significance(RR=1.12,95%CI:1.04-1.20,P=0.002);There was no statistically significant difference(RR=1.15,95%CI:0.99-1.32,P=0.06)between ultrasonic cleaning and manual cleaning for rigid endoscopic instruments in the residual protein method;There was no significant difference between the automatic cleaning of the hard endoscopic instrument and the manual cleaning on the 5x light source magnifying glass(RR=1.13,95%CI:0.99-1.29,P=0.08).Conclusions Compared with manual cleaning,ultrasonic cleaning quality was significantly better than manual cleaning.To a certain extent,small stains in the blind spots and lumens of instruments could be effectively removed,which had the advantages of improving the qualification rate of instrument cleaning and disinfection and sterilization quality;However,there was no significant difference between the automatic cleaning machine and manual cleaning of rigid endoscopic instruments.
