THE TREATMENT
ULTRAVIOLET LIGHT C IN THE TREATMENT OF DIABETIC
ULCERS AND CHRONIC WOUNDS WITH MRSA
The prevalence of antibiotic-resistant bacteria such as methicillin-resistant
Staphylococcus aureus is rapidly increasing in healthcare facilities and spreading to the
community. Methicillin-resistant S. aureus colonize the skin and open wounds and can
interfere with wound healing. Recent studies have shown that ultraviolet light C can kill
antibiotic-resistant strains of bacteria such as methicillin-resistant S. aureus in both
laboratory cultures and animal tissue. This clinical report describes the effects of
ultraviolet light C on wound bioburden and closure in people with chronic ulcers infected
with methicillin-resistant S. aureus.. This case studies also suggests that ultraviolet light
C is a promising adjunctive therapy for chronic wounds containing antibiotic-resistant
bacteria such as methicillin-resistant S. aureus.
KEY POINTS
 Create a bacteria-free environment to treat Decubitus
ulcers.
 Create an environment to enhance the healing and
prevent future infection.
 Sanitize linens and other material coming in contact with
the wound.
 Destroy pathogens rather than permitting mutation to
more difficult drug resistant bacteria.
 The SM2020 has proven to be 99.9% kill rate effective for
the methicillin-resistant strain of S. aureus (MRSA) after
90 seconds treatment. The kill rate reaches 100%
effectiveness after 180 seconds.
 For vancomycin resistant E. faecalis (VRE) the SM2020
was 99.9% effective at 45 seconds and 100% effective @
90 seconds.
THE EQUIPMENT
SM2020 – CUSTOMIZED MEDICAL GERMICIDAL ULTRAVIOLET
SANITIZING SYSTEM
UVC TREATMENT PROTOCOL
Using an application technique that has been prescribed by Nussbaum et.al, our UVmax SM2020
UVC is applied at a distance of 9” vertically above the wound using pre measured and customized
fittings. Before treatment, the customized UVmax SM2020 with a 253.7 nm hot cathode UVC
double tube lamps and generator is warmed up for 5 minutes before being placed above the
wound. The ulcer is to be cleaned with sterile saline, and a layer of petroleum jelly is applied to
the surrounding periulcer skin and any healthy granulation tissue. The wound edges are to be
covered with a drape.
The UVmax SM2020 sanitizing system then is placed above the wound at 180 sec per wound site
at a distance of 9”. This length of time is recommended for the treatment of infected ulcers and
was selected based on MRSA killing rates reported in the in vitro study.
Subsequent and further periodic treatment is based on the recommendation of the physician or
specialist in attendance.
