Contact Irritation Commonly arise due to caustic secretions
injuring superficial skin.
Frequently associated ostomy sites resulting in periwound excoriation and diarrhea leading to severe buttock excoriation.
Both conditions painful and if untreated may result in secondary infection and in ostomy situations may compromise surgical site.

Surgical Wounds Surgical wounds develop due to multiple factors:
Postoperative hydration management
Nature of the underlying pathology Delayed recognition of the wound
Prematurity of the patient Nutritional status of the baby
Association with wound infection

Pressure Ulcers A pressure ulcer is localized injury to the skin
and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in combination with shear.
Among neonates and children, 50% of pressure ulcers are equipment and device related (i.e. nasal prongs, CPAP masks, tubing and lines).
In the pediatric population, the occiput is the largest bony prominence and the most common site of pressure ulcer development.

IV Infiltrates
An unfortunate but common condition in the NICU environment.
Multifactorial etiologies: Fragility of neonatal vasculature, difficulty in line placement and osmotic concentration of infusing fluids.
Key factor is early recognition and immediate cessation of infusion.

Trauma/Shear Injuries/Misc
Typically arise from accidental injury to the skin from external devices, diapers, and clothing.
Extremely premature infants (23-24 weeks) are prone for abrasions and skin tears.
Caution required when removing adhesive probes, Tegaderm (film) dressings, Duoderm (hydrocolloid) dressings.

Infections Neonates and premature infants are at
increased risk of bacterial and fungal infections.
Decreased immunity, foreign devices, prolonged use of antibiotics and acquisition of infection from the environment and caregivers place these infants at risk for serious infections.
An open wound itself may serve as a portal of entry for an infection to arise as well.

Principles of Wound Management
Early recognition and initiation of treatment
Wound must be covered and not allowed to dry. Ideal environment is moist wound
Initial and maintenance debridement by physician will remove nonviable tissue inhibiting healing
Proper recognition and treatment of infection
Appropriate dressings to facilitate granulation
![Page 17: neonatal Wound Management - University Of Texas Wound Care.pdf · Neonatal Wound Management Dr. Rene Amaya Pediatric Wound Care Center of Houston . ... Tegaderm (film) dressings,](https://reader030.vdocuments.mx/reader030/viewer/2022021501/5af33ab37f8b9abc7890d793/html5/thumbnails/17.jpg)
Early recognition and initiation of treatment
Physicians and RNs need to identify babies at risk
for wounds – paralyzed, sedated, edematous, IV sites
Call for assistance and initiate coverage of wound early – wounds should be covered using a safe and effective dressing such as silicone bordered foam.
In extreme premature infants application of Xeroform or petroleum based dressings are ideal.
![Page 18: neonatal Wound Management - University Of Texas Wound Care.pdf · Neonatal Wound Management Dr. Rene Amaya Pediatric Wound Care Center of Houston . ... Tegaderm (film) dressings,](https://reader030.vdocuments.mx/reader030/viewer/2022021501/5af33ab37f8b9abc7890d793/html5/thumbnails/18.jpg)
Debridement Removal of nonviable tissue,
drainage and slough is critical for healing and granulation to occur.
Means of debridement include: Sharp: scalpel, scissors,
forceps Enzymatic: Santyl
Honey
![Page 19: neonatal Wound Management - University Of Texas Wound Care.pdf · Neonatal Wound Management Dr. Rene Amaya Pediatric Wound Care Center of Houston . ... Tegaderm (film) dressings,](https://reader030.vdocuments.mx/reader030/viewer/2022021501/5af33ab37f8b9abc7890d793/html5/thumbnails/19.jpg)
Debridement Santyl® ointment is an enzymatic debriding
ointment which breaks down collagen in necrotic non viable tissue. “Eats bad, leaves good alone”
Medical Grade Honey is an extremely effective debriding agent and facilitates granulation as well. Antibacterial against MRSA, pseudomonas and other
gram negatives. This is not “Little Bear” Honey from HEB.

Granulation/Wound Closure Once effective debridement is obtained,
healing and wound closure facilitated by various specialty dressings Collagen/Silver: Purocal Plus, Prisma Honey Synthetic skin substitute: Acell Matristem,
Oasis Negative Pressure Wound Vac therapy

Overview of Dressing Principles
If it’s too wet – absorb it
If it’s dry – hydrate it
If there’s a hole – fill it
If there’s necrotic tissue – remove it
If there’s healthy tissue – protect it

Why Not Wet to Dry Dressings?
• The only role for Wet to Dry are in cases where debridement of severe slough is necessary.
• In these cases removal of wet to dry dressing is typically not painful because viable tissue has not yet been reached.
• This would be an inexpensive method of mechanical debridement.
![Page 25: neonatal Wound Management - University Of Texas Wound Care.pdf · Neonatal Wound Management Dr. Rene Amaya Pediatric Wound Care Center of Houston . ... Tegaderm (film) dressings,](https://reader030.vdocuments.mx/reader030/viewer/2022021501/5af33ab37f8b9abc7890d793/html5/thumbnails/25.jpg)
Why not Wet-to-Dry Dressings?
No longer standard of care for chronic wounds
In neonatal patients really no application or use
WtD damages healing granulation tissue through adhesion, drying
WtD cools wound bed >> leads to many factors which slows healing process
WtD debridement is painful and only effective on loose slough
![Page 26: neonatal Wound Management - University Of Texas Wound Care.pdf · Neonatal Wound Management Dr. Rene Amaya Pediatric Wound Care Center of Houston . ... Tegaderm (film) dressings,](https://reader030.vdocuments.mx/reader030/viewer/2022021501/5af33ab37f8b9abc7890d793/html5/thumbnails/26.jpg)
Why not Wet-to-Dry Dressings? Compared to other advanced wound dressings
there is nothing within gauze stimulates healing or promotes protection.
Increased risk for infection Not a barrier to environmental bacteria Bacteria shown to penetrate multiple layers of
gauze rapidly.
Saline applied to gauze promotes desiccation/drying.

Silicone Bordered Foam Excellent choice for secondary dressing to cover
wounds in neonates.
Soft and highly conformable foam dressing that absorbs exudate and maintains a moist wound environment.
Atraumatic to the wound and surrounding skin upon removal
May be lifted and adjusted without losing its adherent properties
Minimizes the risk of maceration
May remain in place for several days depending on the condition of the wound.
