Ultrasound gel is not produced as a sterile product, and precautions must be taken to reduce the transmission of viruses and bacteria, Public Health England has warned. The group has issued a three-page document to address the issue of contaminated ultrasound gel.
The new guidelines state that the risk of infection is greater for certain procedures than others, including for the following:
- Invasive procedures, i.e., any ultrasound-guided procedure that involves passing a device through tissue, such as intravenous line insertion or fine-needle aspirate
- Contact with nonintact skin
- Contact with a mucous membrane (e.g., transrectal or transvaginal procedures)
- Examinations on immunocompromised, neonatal intensive care, or critically ill, hospitalized patients (such as in high-dependency settings).
Nonsterile ultrasound gel may be used during low-risk, general examinations on intact skin, noted the document, which has been distributed to members of the British Institute of Radiology.
The agency reminds healthcare practitioners to use only unopened sachets/containers labeled sterile. The gels are for single use, and once opened, they must not be reused, either with other patients or later with the same patient, it says.
