Can Zinc Oxide Have An Impact On Wound Healing?

Start Page: 22
Here is a close-up view of a chronic interdigital ulceration of a patient with type 2 diabetes and poorly controlled blood sugar.
In less than 14 days, the patient had complete epithelialization of the wound due to a combination of daily zinc oxide treatments and local wound care.

Key Practical Considerations
Practically, zinc oxide is an affordable option that even your most non-compliant patients can easily apply at home. By actively facilitating absorption of moisture and odors within the wound, indications for zinc oxide are broad, including:
• post-inflammatory skin following surgery;
• post-matrixectomy/nail surgery;
• draining wounds;
• venous/arterial ulcers (with compression);
• interdigital wounds (does not cause maceration);
• vesicular dermatitis (eczema/tinea pedis);
• full thickness wounds;
• partial thickness wounds;
• heel fissures; and
• puncture wounds.
There are several commercially available products that have zinc oxide, including Dermagran wound cleanser/hydrogel/moisturizer, zinc paste bandages (Unna boot), Double Guard Skin Guard, Zinc Oxide adhering tape, Derma 50 and many diaper rash ointments.
Keep in mind that zinc oxide must be used in conjunction with good overall wound care that includes but is not limited to debridement, compression (venous stasis ulcerations), appropriate offloading, antibiotics and surgical intervention.

Final Notes
Clinically, zinc oxide keeps wounds moist and clean while facilitating wound healing. After cleansing of the wound with saline (along with indicated debridement), one may apply zinc oxide onto the wound in a thick layer followed by a non-adherent dressing or gauze.
Wounds are in constant evolution and though zinc oxide is an excellent and inexpensive tool for your armamentarium, keep in mind that wounds have different needs at different points in time.

Great article. I am trying zinc oxide to heal bilateral lower extremity wounds on an elderly female patient and was looking for an informative article. Thank you
