Medela Invia Mode D'emploi page 8

Osteomyelitis:
– The therapy system should NOT be initiated on a wound with untreated osteomyelitis.
Consideration should be given to thorough debridement of all necrotic, nonviable tissue,
including infected bone (if necessary), and appropriate antibiotic therapy.
Dressings removal:
– Abdominal dressing kit components are not bioabsorbable.
– Always remove all dressing components from the abdomen at every dressing change.
– Count the total number of foam pieces removed from the abdominal wound and
ensure the same number of foam pieces was removed as placed.
Acrylic adhesive:
– The Invia Transparent Film has an acrylic adhesive coating, which may present a risk of an
adverse reaction in patients who are allergic or hypersensitive to acrylic adhesives.
– If a patient has a known allergy or hypersensitivity to such adhesives, do not use the therapy
system.
– If any signs of allergic reaction or hypersensitivity develop, such as redness, swelling, rash,
urticaria, or significant pruritus, discontinue use and consult a physician immediately.
If bronchospasm or more serious signs of allergic reaction appear, seek immediate medical
assistance.
Defibrillation:
– Remove the dressing if defibrillation is required in the area of dressing placement.
Failure to remove the dressing may inhibit transmission of electrical energy and/or patient
resuscitation.
Magnetic Resonance Imaging (MRI):
– Therapy Unit: Invia NPWT systems are not for use in the Magnetic Resonance (MR) Environ-
ment, so do not take an Invia NPWT device into this environment.
– Dressings: After disconnecting from the Invia NPWT system, dressings can typically remain
on the patient with no risk in a MR environment (all components are electrically nonconduc-
tive and nonmagnetic items).
Patients with Spinal Cord Injury (sympathetic nervous system stimulation):
– In the event a patient experiences autonomic dysreflexia (sudden changes in blood pressure
or heart rate in response to stimulation in response to stimulation of the sympathetic
nervous system), discontinue Invia NPWT therapy to help minimize sensory stimulation and
seek immediate medical assistance.
Course of therapy:
– Invia Negative Pressure Wound Therapy Instructions advise 24 hours therapy without inter-
ruption.
– If therapy is discontinued for more than 2 hours, the dressing should be replaced and
therapy restarted by a physician. If the therapy needs to be interrupted, the tubing should be
clamped and the ends of the tubing protected.
