Abstract:
Objective To observe the efficacy of a medical disinfectant ultrasonic coupling agent on the killing of five clinically isolated multidrug-resistant organisms(MDROs).Methods From March 2016 to May 2017,a disin-fection ultrasonic coupling agent containing active ingredient,including triclosan and propylene glycol,was used to conduct carrier quantitative germicidal test on five clinically isolated MDROs,the killing efficacy to MDROs was ob-served.Results After 1.5,3.0,and 4.5 minute disinfection time,the killing logarithms values of disinfection ultra-sonic coupling agent to five MDROs(multidrug-resistant Acinetobacter bau m annii[MDR-AB],methicillin-resistant Staphylococcus aureus[MRSA],multidrug-resistant Pseudomonas aeruginosa[MDR-PA],carbapenem-resistant Klebsiella pneumoniae[CRKP],and extended-spectrum β-lactamase Escherichia coli[ESBLs-EC])were all>3.0. Conclusion Medical disinfection ultrasonic coupling agent can effectively kill five common MDROs,and can take the place of disinfectant during ultrasonic examination.
