if deemed by the treating physician to provide a complete protective barrier. If using non-ad-
herent materials, ensure that they are secured in a manner as to maintain their protective posi-
tion throughout therapy. Caution should be taken when treating large wounds that may contain
hidden vessels, which may not be readily apparent. The patient should be closely monitored
for bleeding in a care setting deemed appropriate by the treating physician.
Infected blood vessels: Infection may erode blood vessels and weaken the vascular wall
which may increase susceptibility to vessel damage through abrasion or manipulation.
Infected blood vessels are at risk of complications, including bleeding, which, if uncon-
trolled, could be potentially fatal. Extreme caution should be used when therapy is
applied in close proximity to infected or potentially infected blood vessels.
(Refer to protect vessels and organs section above.)
Hemostasis, anticoagulants and platelet aggregation inhibitors: Patients without adequate
wound hemostasis have an increased risk of bleeding, which, if uncontrolled, could be poten-
tially fatal. These patients should be treated and monitored in a care setting deemed appropri-
ate by the treating physician.
Caution should be used in treating patients on doses of anticoagulants or platelet
aggregation inhibitors thought to increase their risk for bleeding (relative to the type and
complexity of the wound). Consideration should be given to the negative pressure set-
ting and therapy mode used when initiating therapy.
Hemostatic agents applied at the wound site: Non-sutured hemostatic agents (for example,
bone wax, absorbable gelatin sponge, or spray wound sealant) may, if disrupted, increase the
risk of bleeding, which, if uncontrolled, could be potentially fatal. Protect against dislodging
such agents. Consideration should be given to the negative pressure setting and therapy mode
used when initiating therapy.
Sharp edges: Bone fragments or sharp edges could puncture protective barriers, vessels, or
organs causing injury. Any injury could cause bleeding, which, if uncontrolled, could be poten-
tially fatal. Beware of possible shifting in the relative position of tissues, vessels or organs
within the wound that might increase the possibility of contact with sharp edges. Sharp edges
or bone fragments must be eliminated from the wound area or covered to prevent them from
puncturing blood vessels or organs before the application of therapy. Where possible, com-
pletely smooth and cover any residual edges to decrease the risk of serious or fatal injury,
should shifting of structures occurs. Use caution when removing dressing components from
the wound so that wound tissue is not damaged by unprotected sharp edges.
Infected wounds: Infected wounds should be monitored closely and may require more fre-
quent dressing changes than non-infected wounds, dependent upon factors such as wound
conditions and treatment goals. Refer to dressing application instructions for details regarding
dressing change frequency. As with any wound treatment, clinicians and patients/caregivers
should frequently monitor the patient's wound, periwound tissue and exudate for signs of infec-
tion, worsening infection, or other complications. Some signs of infection are fever, tenderness,
redness, swelling, itching, rash, increased warmth at the wound or periwound area, purulent
discharge, or strong odor. Infection can be serious, and can lead to complications such as
pain, discomfort, fever, gangrene, toxic shock, septic shock and/or fatal injury. Some signs or
