There are two ways traxi can be applied and used or applied: 1) sterile, 2) non-sterile. Depending on what you are currently using to retract the panniculus, it is likely done in a non-sterile fashion. Tape, straps, etc. are not sterile, and traxi can be used in the same exact way. However, if you want to prep the patient before applying the device to ensure a sterile field, traxi is sterile and can applied once the prep is completely dry.
