摘要

Abstract

Objective

The purpose of this study is to understand the working habits of healthcare workers and the contamination of ultrasound instrument surfaces in the ultrasound clinic of infectious disease hospitals

and to explore the effect of disposable medical disinfectant wipes on disinfecting the surface of ultrasound instruments

so as to provide reference for the infection control in the department of medical ultrasound.

Methods

A questionnaire survey w

as conducted on the working habits of 24 staff in the ultrasound department. According to the

Hygienic Standard for Hospital Disinfection

(2012-GB15982)

the surfaces (probes

wires

and keyboards) of 16 ultrasound diagnostic instruments currently in use were examined for colony sampling and cleanness. Disposable medical disinfectant wipes containing compound double-chain quaternary ammonium salt were used to wipe and disinfect the probe

and the samples were sampled and tested again after disinfection. A total of 256 samples were effectively detected. The number of colonies and cleanness of each tested site before and after disinfection were compared and analyzed.

Results

The frequency of work clothes replacement

hand hygiene implementation

frequency of ultrasound probe cleaning and disinfection in the clinic exceeding standard were lower than those in the clinic non-exceeding standard. The cleanliness of 256 samples after cleaning and disinfection did not exceed the standard

and the number of colonies exceeding the standard was significantly reduced after disinfection (

0.001). The contamination of the probe

instrument keyboard surface

and wire using disposable medical disinfectant wipes after cleaning and disinfection was significantly improved compared to the contamination before cleaning and disinfection. There was a statistically significant difference between the ultrasound probes before and after cleaning and disinfection (

0.05).

Conclusion

Bad working habits of medical staff lead to serious pollution of instrument surfaces. The surface of the medical ultrasonic diagnostic instruments

especially the surface of the ultrasound probe

is seriously polluted. The disinfectant wipe containing compound double-chain quaternary ammonium salt has a good disinfection effect on ultrasound probes.
