The medical technology guidance advises using the 3M Tegaderm CHG IV securement dressing for critically ill patients who need a central venous or arterial catheter in intensive care or high dependency units. Catheters are thin tubes put into the body which can be used to deliver liquids such as antibiotics or other drugs, so avoiding the need for frequent needle injections.
Tegaderm CHG dressing is a sterile transparent semipermeable polyurethane adhesive dressing, with an integrated gel pad containing the antibacterial agent chlorhexidine gluconate (which is a widely used antiseptic and disinfectant).
The evidence considered showed that the Tegaderm CHG dressing offers better protection against catheter-related bloodstream infection than sterile semipermeable transparent dressings. If using the Tegaderm CHG dressing becomes standard practice, the reduction in infections has the potential to save the NHS in England an estimated £4million to £10million each year.
