Evaluation of the role of ultrasound machines as a source of nosocomial and cross-infection.
OBJECTIVE
To evaluate the potential role of ultrasonography probes and coupling gel for cross-infection in patients undergoing ultrasonography; to describe a cost-effective method of probe handling; and to emphasize the importance of position of the probes in the boxes.


METHODS
Cultures were taken from 43 probes used in different scanning regions. Cultures were also taken from probe boxes and coupling gel.


RESULTS
After abdominal scanning, cleaning with paper seems to be effective, but even wiping with alcohol is insufficient for inguinal and axillar regions. Before scanning of these areas is started, cleaning the inguinal and axillar regions with alcohol reduces the contamination risk. Placing the probes downward in boxes also increases the risk of contamination.


CONCLUSIONS
Wiping the probes with dry paper seems to be effective only for abdominal scanning; for inguinal and axillar scanning, cleaning the region with alcohol before scanning seems more appropriate. Placing the probes downward in boxes may also be a source of contamination.
