Sterile ultrasound gel in single-use sachets or tubes should be used in the following scenarios:
Any ultrasound-guided procedure that involves passing a device through skin
If is potential risk of transient contamination of the skin
In labour where there is high likelihood of caesarean-section or invasive instrumentation during delivery
Where the ultrasound examination is near to an indwelling invasive device, such as an intravenous vascular access device or suprapubic catheter
Where there is contact with a mucous membrane when a probe cover is required, sterile single-use gel should be used inside and outside of the probe cover
In all intensive care, including neonatal intensive care, high-dependency units
Non-sterile ultrasound gel in single use and multi-patient use containers may be used:
During examinations of low-risk patients with intact skin and where there is no contact with mucous membranes
In examinations that do not involve invasive procedures
