Cleaning and disinfecting procedure of ultrasound machine and probe in the Surgical ICU of La Pitié-Salpêtrière hospital

Reduction of environmental contamination
     Avoid as much as possible contact between ultrasound machine and patient's environment
     Use single-patient package of coupling gela
     Limit the probe contact to patient's skin
     During examination, restrict contacts with the ultrasound machine to the probe and the keyboard
     At the end of the examination, leave the probe on the bedb
Disinfection procedure at the end of the examination
     Cleaning of examiner's hands
     Cleaningc of the ultrasound machine, including the probe holder
     Cleaning of the keyboard
     Removing of gel with paper toweld
     Cleaning of the probeb
     Spontaneous air drying

aAvoid using a gel bottle because the tip may be contaminated by contact with the probe or the patient's skin. Such contact may result in the contamination of the gel contained in the bottle. bThe contaminated probe should not be placed in the probe holder before decontamination. cWe use a detergent-disinfectant based on a quaternary ammonium compound with a processing time of at least 60 seconds. It cleans by removing organic material and suspending grease or oil and disinfects. After 11 years of experience, we have not found evidence of this causing material damage, including significant alterations of acoustic properties of the probe. dRemaining ultrasound gel on the lung ultrasound probe has shown bacterial growth when left overnight [20].
