OASIS® Matrix is a well-studied solution for successful wound management

What is OASIS Matrix?

OASIS Matrix is a wound management device made of a naturally derived material called small intestinal submucosa, or SIS. OASIS Matrix is approved for use in a wide array of acute and chronic wounds.

How will OASIS Matrix be applied to my wound?

In most cases, OASIS Matrix will be applied at a wound care center or as an outpatient hospital procedure by a doctor. First, the healthcare provider will clean the wound area. Because OASIS Matrix comes packaged as dry sheets, the healthcare provider will simply cut the right amount of material and apply it to the wound. He or she will then make sure the OASIS Matrix is moistened with saline or a wound gel and correctly covered. The coverings, or wound dressings, ensure the product has the chance to work without being disturbed.

It is important that you do not touch or remove the wound dressings or OASIS Matrix unless your healthcare provider gives you specific directions otherwise. See the question below regarding side effects and possible complications.

After seven days, or when your healthcare provider recommends, your healthcare provider will remove the wound dressings to check on the wound’s progress. He or she may decide to continue applying new OASIS Matrix until the wound is closed.

Will there be any side effects or possible complications?

As with any medical device, complications are possible. Let your doctor know right away if your wound develops any of the following conditions:

  • Redness
  • Warmth
  • Swelling
  • Blistering
  • Pain
  • A discharge of pus
  • An allergic reaction

If you are aware of having a pig or pig products allergy, do not apply OASIS. An allergic reaction may involve itching or redness.

Additionally, be aware of any other symptoms of illness, like fever or nausea, which may indicate an infection. If your doctor determines that you are experiencing complications from the OASIS Matrix, he or she will promptly remove it.

After OASIS Matrix is applied to my wound, how do I protect the area?

For best results, always follow all your doctor’s directions. It is important to keep the entire area surrounding your wound completely dry at all times. When bathing, keep your wound and dressings out of the water. Additionally, do not remove or change your wound dressings unless instructed by your doctor. If you are instructed to change the dressings, only remove the outer dressings. Do NOT remove the primary dressing or any form of the OASIS Matrix product that remains in the wound bed (the layer immediately covering your wound) unless directed by your doctor.

If your leg has compression dressings, try to elevate when possible. Do NOT remove the compression dressings unless directed by your doctor.

If you are instructed to moisten your wound during a dressing change, do NOT remove the primary dressing (the layer immediately covering your wound). Instead, apply a wound gel or sterile saline to the outside of the primary dressing.
