Abstract
PURPOSE: To determine suitable procedures for decontaminating ultrasound probes. METHODS: We investigated bacterial transmission via ultrasound probes that were not wiped, wiped with a plain paper towel, or wiped with an ethanol-soaked paper towel. RESULTS: The unwiped probes transmitted large numbers of bacteria, which were markedly reduced by wiping the probes with a plain paper towel, and almost completely eliminated by wiping with an ethanol-soaked paper towel. CONCLUSION: Improperly decontaminated ultrasound probes can transmit bacteria among patients. Ultrasound probes should be decontaminated by wiping with a paper towel after examinations to prevent bacterial transmission. Plain or ethanol-soaked paper towels should be used depending on the situation.
