Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Thirty patients of 18-85 years of age, with 2-30 cm2 pressure ulcers or post-op wounds, will be recruited and treated with either wound dressing containing silver or wound dressings containing copper oxide microparticles. The efficacy of the two types of dressings in reducing the size and improving the condition of the wounds will be compared.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will be divided into 3 periods. Patients with pressure ulcers or post-operation wounds with wound areas of 2-30 cm2, who will accept participating in the study, pass all the accepted inclusion criteria, and sign the informed consent form, will be recruited. Then they will be treated with silver dressings for up to three weeks (first period). In case that the wounds will not show a reduction of at least 50% of the wound area during the first period, then the wounds will be treated with the copper oxide dressings for at least 3 weeks (second period). In case that there will be a clear improvement during the second period, the wounds may continue to be treated with the copper oxide dressings or with any other wound dressings according to the treating physician judgement and decision for an additional 3 weeks (third period) or earlier if the wound will be closed.

4. Having a body mass index (BMI) \<40 Kg/m2.
5. Glycosylated haemoglobin (HbA1c) \<12.0%.
6. Not undergoing any systemic or topical antibiotic treatment for the wound for a week before enrollment in the study.
7. The patient is able and eligible to sign written informed consent and participate in the study.
8. Be available for the entire study period, and ability and willingness to adhere to the requirements of the study.
9. In case of post-op wounds, at least three weeks post-op, wounds that do not show significant healing (reduction of wound size of less than 50% in 3 weeks)

7. Individuals using and need to continue use any type of topical agents in or on the wound.
8. Any form of substance abuse (including drug or alcohol abuse, excluding cannabis), psychiatric disorder or any chronic condition susceptible, in the opinion of the investigator, of interfering with the conduct of the study.
9. Females who are pregnant, lactating, of child-bearing potential.

12. The size of the wounds is reduced by more than 50% during the three weeks presiding the study.
13. Wounds in which local pressure cannot be avoided due to protruding bone, or any other complex rehabilitation procedure.
14. Wounds determined to be infected wounds.
15. Wounds that are considered to necessitate debridement in the operation room during the study.
16. Wounds that necessitate antibiotic treatment or needed antibiotic treatment one week prior to the trial.
17. Necrotic wounds.
18. Wound with tunnels of more than 3 cm.
