Abstract

Provided is a method of treating skin ulcers and related complications in patients by administering an oxidative reduction potential (ORP) water solution that is stable for at least twenty-four hours.

Claims (35)

1. A method of treating an infected diabetic foot ulcer in a patient comprising administering an oxidative reductive potential (ORP) water solution to the patient in an amount effective to treat the skin ulcer, wherein the solution has a pH of about 6.4 to about 7.8 and is stable for at least two months, wherein the ORP water solution comprises anode water and cathode water, and wherein the ORP water solution comprises free chlorine species at a level of from about 30 ppm to about 100 ppm, and wherein the free chlorine species comprises at least one of: hypochlorous acid present in an amount of from about 15 μm to about 35 μm and sodium hypochlorite present in an amount from about 25 μm to about 50 ppm.

2. The method of claim 1 , wherein the solution is stable for at least one year.

3. The method of claim 1 , wherein the pH is from about 7.4 to about 7.6.

4. The method of claim 1 , wherein the cathode water is present in an amount of from about 10% by volume to about 50% by volume of the solution.

5. The method of claim 1 , wherein the cathode water is present in an amount of from about 20% by volume to about 40% by volume of the solution.

6. The method of claim 1 , wherein the anode water is present in an amount of from about 50% by volume to about 90% by volume of the solution.

7. The method of claim 1 , wherein the solution comprises hypochlorous acid in an amount of from about 15 ppm to about 35 ppm and sodium hypochlorite in an amount of from about 25 ppm to about 50 ppm.

8. The method of claim 1 , wherein the solution is administered to the patient by washing or irrigating the ulcer with the solution.

9. The method of claim 1 , wherein the solution is administered to the patient by soaking the ulcer in the solution.

10. The method of claim 9 , wherein the ulcer is soaked in the solution for at least one minute.

11. The method of claim 9 , wherein the ulcer is soaked in the solution for at least two minutes.

12. The method of claim 1 , wherein the solution is administered to the patient by dressing the ulcer with a wound dressing saturated with the solution.

13. The method of claim 1 , further comprising debriding the ulcer.

14. A method of reducing the microbial load of an infected diabetic foot ulcer in a patient comprising treating the ulcer in accordance with the method of claim 1 .

15. A method of decreasing the recurrence rate of an infected diabetic foot ulcer in a patient comprising treating the ulcer in accordance with the method of claim 1 .

16. A method of decreasing the likelihood of dehiscence of an infected diabetic foot ulcer in a patient comprising treating the ulcer in accordance with the method of claim 1 .

17. A method of decreasing the likelihood of amputation resulting from an infected diabetic foot ulcer in a patient comprising treating the ulcer in accordance with the method of claim 1 .

18. A method of decreasing the likelihood of systemic inflammatory response syndrome resulting from an infected diabetic foot ulcer in a patient comprising treating the ulcer in accordance with the method of claim 1 .

19. A method of decreasing the likelihood of sepsis resulting from an infected diabetic foot ulcer in a patient comprising treating the ulcer in accordance with the method of claim 1 .

20. A method of treating an infected diabetic foot ulcer in a patient:

(1) washing or irrigating the ulcer with an oxidative reductive potential (ORP) water solution;

(2) soaking the ulcer in the ORP water solution;

(3) dressing the ulcer with a wound dressing saturated with the ORP water solution, and,

(4) optionally repeating steps (1)-(3),

wherein the solution has a pH of about 6.4 to about 7.8 and is stable for at least two months, wherein the ORP water solution comprises anode water and cathode water, wherein the ORP water solution comprises free chlorine species at a level of from about 30 ppm to about 100 ppm, and wherein the free chlorine species comprises at least one of: hypochlorous acid present in an amount of from about 15 ppm to about 35 ppm and sodium hypochlorite present in an amount from about 25 ppm to about 50 ppm.

21. A method of treating an infected diabetic foot ulcer in a patient:

(1) debriding the ulcer;

(2) washing or irrigating the ulcer with an oxidative reductive potential (ORP) water solution;

(3) soaking the ulcer in the solution for at least two minutes;

(4) drying the ulcer for at least two minutes;

(5) dressing the ulcer with a wound dressing saturated with the solution; and

(6) optionally repeating steps (1)-(5),

wherein the ulcer is an infected Grade 2 or Grade 3 foot ulcer, said ulcer having a surface area of at least 2.0 cm 2 , wherein the solution has a pH of about 6.4 to about 7.8 and is stable for at least two months, wherein the ORP water solution comprises anode water and cathode water, wherein the ORP water solution comprises free chlorine species at a level of from about 30 ppm to about 100 ppm, and wherein the free chlorine species comprises at least one of: hypochlorous acid present in an amount of from about 15 ppm to about 35 ppm and sodium hypochlorite present in an amount from about 25 ppm to about 50 ppm.

22. The method of claim 21 , further comprising repeating steps (1)-(5) at least one time.

23. The method of claim 21 , further comprising repeating steps (1)-(5) until the ulcer is substantially healed.
