Case Studies of Hard-to-Heal Wounds Treated Successfully with an Antimicrobial Foam Dressing

An estimated 6.7 million Americans are living with chronic wounds.1,2 A chronic wound is one that fails to progress through a normal, orderly, and timely sequence of repair, or in which the repair process fails to restore anatomic and functional integrity after three months3 Some chronic wounds can take decades to heal and can ultimately lead to isolation and family distress.3

A summary of recent case studies illustrates the successful use of an antimicrobial foam wound dressing* as part of the overall treatment approach to healing complex recalcitrant wounds.

*The product used in the case studies was RTDTM Wound Dressing, Keneric Healthcare, Irvine, Texas. The RTDTM dressing was acquired in 2018 by DermaRite Industries, LLC and re-branded as DermaBlue+TM Foam. No data or conclusions have been altered in the case study materials.

Wound Types: The patients featured in the case studies suffered from a variety of longstanding wounds, including diabetic wounds, dehisced surgical incisions, vascular leg ulcers, pressure injuries and wounds due to Pyoderma Gangrenosum. 

Care Settings: All patients were being cared for in a nursing home or at home. Each patient’s wound care treatment plan was developed and directed by a wound care physician or a certified wound care nurse. 

Prior Course of Treatment: Patients had been treated for 60 days to 450 days prior to the addition of DermaBlue+TM Foam to the comprehensive treatment plan. A variety of dressings in the following categories had been used to manage moisture and bioburden and support autolytic debridement:

Some of the patients also underwent surgical debridement or sharp debridement, and some received synthetic skin substitutes, IV antibiotics, hyperbaric oxygen treatment and/or NPWT as part of their wound care. 

Outcomes Achieved following the addition of DermaBlue+TM Foam to the treatment plan: 

As part of a comprehensive plan of care, DermaBlue+ TM Foam worked where other dressings failed. 87% of patients achieved wound healing in less than 90 days following the introduction of DermaBlue+TM Foam to their dressing regimen. 

DermaBlue+™ Foam and DermaBlue+™ Foam Transfer are flexible, ready-to-use absorbent antimicrobial foam dressings infused with Methylene Blue, Gentian Violet, and silver zirconium phosphate.

DermaBlue+™ Foam combines triple-action antimicrobial protection with a unique micro-pore foam that wicks exudate away from the wound and kills over 99% of bacteria within, helping to disrupt the formation of biofilm and aiding in the healing of even the most challenging chronic wounds
