Benefits of technology

The present invention provides new methods and compositions for topical wound care that overcome the disadvantages of previous treatments. Specifically, the invention provides a composition that includes lidocaine in a carrier for improved treatment of wounds on a patient. The composition can be applied directly to the wound and can enhance the healing process. The invention also includes a wound dressing that includes lidocaine in a carrier for further enhancement of healing. The invention can be used in combination with other treatments such as zinc oxide ointment and can be applied in different ways to the patient. Overall, the invention provides new and effective methods for treating wounds.

Problems solved by technology

Wounds are a significant problem among the geriatric and nursing home population, especially at the end of life.
Pressure ulcers alone exact a tremendous human and financial toll, costing on average more than $1,200 per patient per month to treat.
Diabetic ulcers similarly result in significant morbidity and costs, with diabetics accounting for approximately 82,000 amputations annually in the U.S., averaging $30,000 per amputation.
Especially among the terminally ill, there is little expectation of healing a wound due to the population being malnourished, immobile and with many comorbidities that inhibit and delay wound healing.
In addition, often the patient will not live long enough to heal a wound.
While these can be effective, they are very expensive and healing times are still measured in weeks or months.

STUDIES

Case One

[0051] A 91 year old white male hospice patient with end stage dementia. Wound on gluteal cleft had been worsening under prior treatment of Collagenase (Santyl®) and Polysporin® ointment (bacitracin zinc-polymyxin B). Prior to treatment with the method and composition of the present invention, the wound measured 4.5 cm3 and was tender. Treatment consisted of initially packing gauze strips coated with 2% viscous lidocaine in the wound bed. After wound had reduced in size to prevent packing (23 days after initial treatment), dressing containing 2% viscous lidocaine was applied to wound. FIG. 7 depicts the results of treatment of the gluteal wound. As can be seen from astonishing results depicted in FIG. 7, the gluteal cleft wound was unexpectedly reduced in size by approximately 85% in 23 days and completely healed in less than 80 days utilizing the present invention.

case three

[0053] A 40 year old white female hospice patient with end stage multiple sclerosis had a coccyx wound as well as multiple foot and leg wounds. Prior to treatment utilizing the present invention, the patient had 12 wounds with the coccyx wound having a surface area totaling 48 cm2. Treatment utilized the composition and method of the present invention: a 2% viscous lidocaine solution with bacitracin zinc-polymyxin B powder. The composition comprised approximately 18-19.8 mg of lidocaine hydrochloride, 500-1000 units polymyxin B sulfate and 25-50 units of bacitracin zinc per gram of the composition. The unexpected and astonishing results of the present invention are depicted in FIG. 9 which illustrates the amazing reduction in wound volume with complete healing in under 60 days.

[0054] These case studies demonstrate that the compositions and methods according to the present invention exhibit surprising results in the mitigation or elimination of non-healing wounds on patients.
