Electrodes or Conductive Gel: Do not allow the PREVENA™ Dressing to come in contact with EKG
or other electrodes or conductive gels during electronic monitoring or when taking electronic
measurements.
Dressing Components: The PREVENA™ Dressing contains ionic silver (0.019%). Application of
products containing silver may cause temporary tissue discoloration.
•
Always use PREVENA™ Dressings and canisters from sterile packages that have not been
opened or damaged.
•
All dressing components and canisters of the PREVENA™ Incision Management System are for
single use only. Do not re-use any component of this system.
•
To avoid trauma to the skin, do not pull or stretch the adhesive border of the dressing during
application.
Compressive Garments or Dressings: Avoid tight compressive garments or dressings (such as
surgical bras, elastic bandage wraps or abdominal binders) to prevent forcibly pressing the
PREVENA™ Dressing into soft tissue.
PREVENA™ INCISION MANAGEMENT SYSTEM DRESSINGS
The PREVENA™ Incision Management System features PREVENA CUSTOMIZABLE™ Dressings. These
dressings contain a skin interface layer that includes 0.019% ionic silver. Silver in the interface layer
of the PREVENA™ Dressing is not intended to treat infection, but to reduce bacterial colonization in
the fabric. In vitro log reduction tests, conducted without application of negative pressure, exposed
samples of the skin interface layer to a six log challenge of each of the microorganisms listed below.
Following inoculation, samples were tested for microbial counts immediately (day 0) and after
incubation at 90˚F (32˚C) in diluted nutrient broth for 1, 3, 5 and 7 days.
The log reductions from the day 0 values are provided in the table below.
