Abstract

OBJECTIVE:

This study aims to evaluate the comparative performance of a resorbable nanofiber wound matrix (Restrata Wound Matrix; Acera Surgical Inc, St Louis, MO) and a bilayered collagen xenograft (Integra Bilayer Matrix Wound Dressing; Integra, Plainsboro, NJ) in healing critical full-thickness cutaneous wounds in a preclinical porcine model.

MATERIALS AND METHODS:

Full-thickness cutaneous wounds were created in Yucatan miniature swine and treated with either the nanofiber wound matrix or xenograft. Wound area was measured and inflammation and healing were assessed until euthanasia at day 15 or 30, at which time tissue samples were harvested for histopathology.

RESULTS:

Wounds treated with the nanofiber wound matrix demonstrated significantly faster wound areal reduction, less inflammation, greater neovascularization, more collagen maturation, and superior quality of healing compared with wounds treated with the xenograft.

CONCLUSIONS:

The nanofiber wound matrix is an effective wound healing material that may offer a unique alternative in the treatment of challenging refractory wounds.
