Purulence/Infection POD 0-12
Previous Previous | Next Next

Remove all signs of possible purulence

- Aspirate or evacuate by incising/rolling

- Treat with topical antimicrobials - Irrigate INTEGRA™ Meshed Bilayer Wound Matrix sites at seams/edges and beneath the silicone layer with a topical antimicrobial such as sulfamylon 5 solution/slurry, G-U irrigant, or silver nitrate 0.5% solution. Irrigate frequently (2-6 times daily).

- Culture and initiate systemic antibiotics based on the clinical  judgement of the practitioner

If aggressive treatment of purulence is not successful as evidenced by increasing purulence/pus, non-take of INTEGRA™ Meshed Bilayer Wound Matrix (i.e., a "floating" sheet) or silicone separation, then the affected area needs to be removed.

- Remove only the affected area using "windowing" (remove dressing over area to be treated, creating a "window"), treat with topical antibiotics

- Treat as open wound until infection is resolved. Once infection is resolved, apply new INTEGRA™ Meshed Bilayer Wound Matrix sheet or treat with temporary covers. If applying an epidermal autograft, the granulation tissue should be removed, revealing healing tissue underneath.

Areas of Incomplete INTEGRA™ Meshed Bilayer Wound Matrix Take (i.e., inadequate formation) POD 5 or higher

Areas of incomplete take or detachment of the INTEGRA™ Meshed Bilayer Wound Matrix can result from mechanical dislodgement (due to shear, improper splinting, PT), infection, hematoma, granulation tissue formation, premature silicone separation or damaged matrix.

There are several options for treating areas of incomplete take depending on the size of the area:

- Areas under 2 sq cm should be monitored for infection but not removed until time of epidermal grafting

- Areas over 2 sq cm should be removed and treated by either (1) re-application of new INTEGRA™ Meshed Bilayer Wound Matrix or (2) STSG

- Identification of poor INTEGRA™ Meshed Bilayer Wound Matrix take is identified by poor color and lack of adherence (lateral movement of matrix under finger pressure)
