(CS-007(GR-001)) Novel Application of Fish Skin Grafts in Neonatal Wounds

Introduction: Wounds that arise in neonatal infants often pose unique concerns when considering options for treatment. Whereas such wounds are inherently acute, wound management in this unique patient population must consider the long-term effects of treatment that will affect the future function of the limb and the aesthetic qualities of a residual scar later in life. Identifying safe and effective dressings to treat complex wounds in this fragile population is often challenging for pediatric wound care specialists. In this case series, a fish skin graft (FSG) was applied to three neonatal patients with IV extravasation injuries to assess the safety and efficacy of such a product in this age group. The FSGs are a derivative of intact skin obtained from North Atlantic cod. FSGs are effective in the treatment of older children¹, however, no prior experience with this product in neonatal patients has been reported.

Methods: Three neonatal patients ( < 30 days of life) with IV extravasation injuries of the extremities are illustrated. The FSG was applied at the bedside over healthy wound beds after successful debridement of nonviable tissue. The grafts were secured with non-adherent dressings and left in place for seven days without disturbing the underlying graft. After one week, the wounds were examined.

Results: In each case, the wounds rapidly healed after a single application of an FSG. No complications were encountered. Full closure was obtained without compromising the range of motion of the extremity. No contractures developed and residual scars were minimal. The parents were extremely pleased with the outcomes.

Discussion: This case series illustrates the first application of an FSG in the neonatal population. The FSG was easily applied at the bedside, required minimal maintenance, and expedited rapid wound healing after a single application. No complications developed, and residual scars were minimal. FSG reduces scaring and contracture in animal studies and adult clinical trials, but our findings are novel to neonatal patients^2,3. The product proved to be a safe and effective option for wound closure and supports additional larger studies for use in neonates and premature infants.
