Any of the following infection control measures seems to be common practice for PIV catheters inserted under ultrasound guidance: - Wipe the transducer with the same (or similar) antiseptic used to prep the skin, and use sterile gel. - Apply dressing material to the front of the transducer (e.g. Tegaderm or similar) and use sterile gel on the outside - Cover the transducer completely with a sterile sleeve; use normal gel inside and sterile gel outside Which one of these methods do you use in your practice? Would you recommend in favor or against any of these? Do you do something different? Thank you.
