Abstract: A full-surround contact antimicrobial dressing is disclosed. The dressing includes a transparent body that covers a skin insertion site through which a catheter assembly passes for disposal within the body of a patient. The transparency of the dressing body enables inspection of the skin insertion site. In one embodiment, therefore, an antimicrobial full-surround contact dressing for use with a medical device inserted into a skin surface of a patient via a skin insertion site is disclosed and comprises a transparent flat body, an antimicrobial adhesive substance disposed on a bottom surface of the body, and a slit defined in the body. The slit is configured to enable the body to be placed fully around a perimeter of the medical device on the skin surface at the skin insertion site such that the bottom surface of the body fully surrounds and contacts the skin insertion site.
