简要总结
Patients who meet the inclusion criteria will be provided with fibrillar collagen powder dressing. The powder dressing will be used in accordance with its label. After cleansing the wound by the clinical site staff, the powder is placed directly on the wound, and then the wound will be covered with an appropriate moisture retentive secondary dressing. Patients will visit the clinic twice a week to have the powder re-applied. Wound evaluations will take place once a week at the outpatient clinic, with the intervention lasting up to twelve weeks. Concurrent standard of care, such as compression for venous ulcers, will be provided.
