GuardIVa: a novel antimicrobial haemostatic IV dressing: Part 1.

摘要

HemCon GuardIVa(R) is a hydrophilic polyurethane sponge dressing impregnated with the broad spectrum antimicrobial agent chlorhexidine gluconate (CHG) and a proprietary formulation of the haemostatic agent oxidized cellulose. The intended use of the dressing is to absorb exudate, cover and protect catheter sites. Some common applications include intravenous (IV) catheters, other intravenous catheters and percutaneous devices. GuardIVa is also the only IV site dressing indicated to control surface bleeding from percutaneous access sites. A clinical study in healthy human volunteers has demonstrated the ability of the GuardIVa dressing to significantly suppress skin flora re-growth. The antimicrobial and haemostatic efficacy of the GuardIVa dressing and its effects on wound healing have also been demonstrated by independent laboratories in a number of in-vitro and in-vivo tests. These data suggest that GuardIVa would be an effective component as part of a catheter site regimen to help reduce skin microbial colonization, provide sustained antimicrobial protection against the major organisms responsible for catheter-related blood stream infections (CR-BSIs) and prevent the risk of CR-BSIs.
