In 2000 my Mother broke her hip and while hospitalized developed a coccyx pressure wound...
Over the years, many times the wound was within centimeters of closing. But a medical setback
would always interfere. In 2004 a trip to the hospital resulted in MRSA (Methicillin resistant
Staphylococcus aureus infection) and the chronic wound had now become Stage IV. The location of the
wound and other medical factors had contributed to a chronic wound that seemed not only destined
Three times on the wound vac....
The first time the wound almost closed and the wound vac therapy was stopped. The doctor
was sure the wound was within a week of closing entirely. Only the wound did not close as
a trip to the hospital resulted in another MRSA infection. The wound quickly reverted to
Stage IV and while on the IV antibiotics the wound vac was reapplied. The second time on
the wound vac results were not the same and so the wound vac was removed. Mom came
home after her course of IV antibiotics greatly discouraged.
The wound had developed deep undermining and tunneling measured from noon to 6 o’clock.
The wound care now consisted of alginate and the wound stabilized but little progress in
healing. Weekly visits to the Wound Care Center and after several weeks of no progress at
all the care plan moved to another product, the Johnson & Johnson Promogran Prisma
Matrix Dressing. The wound began to respond with new granulated tissue. Again there was
talk of the chronic wound finally healing. But another visit to the hospital in 2007 resulted
in another bout with MRSA and a third attempt with the wound vac. This time there were
results with the wound vac. After the full course of IV antibiotics Mom came home without
the wound vac as the wound was now classified as Stage II. The at home plan consisted of
exclusive use of the Johnson & Johnson Promogran Prisma Matrix Dressing.
However, Mom did come home with a secondary infection and the antibiotics left her woozy
and tired. But the wound healing progress continued. Due to the location of the wound and
the bowel problems resulting from the antibiotics, frequent dressing changes were now
required. This time the Prisma was applied to the wound in the AM and PM dressings rather
than just once a day. Initally the wound required one and a half Prisma (4.34 Hexigon size),
than one Prisma... than a half of a Prisma until the wound closed...
A few tips based upon a caregiver’s experience
Wound application - cut or tear the Prisma to fit the wound - apply directly to the wound bed like fitting
the pieces of a puzzle, Because of its flexibilty the Prisma was used in the deep cavity, undermining
and tunneling of the wound.
Note - if the wound bed is dry, wounds with low or no exudate, hydrate the Prisma Matrix with saline.
Pressing the dressing (breaks surface tension) may be needed to help faciliate the hydration and also
to get a good contact with the wound.
Don’t be surprised if the next dressing change the Prisma Matrix has turned gelantinous, become
smaller or even disappeared entirely. The Prisma Matrix is biodegradable and is naturally absorbed by
the wound
