Conditions: Diabetic Foot Ulcer; Venous Leg Ulcer; Pressure Ulcer; Wound Infection; Acute Wounds

Summary: evaluation of the efficacy (wound epithelialization and time to closure) and tolerance (emergence and nature of adverse event) of the new urgo awc_008 and urgo awc_022 dressings in local management of acute and chronic wounds at risk of local infection or with clinical signs of local infection

prospective multicenter, non comparative clinical investigation this is a prospective multicenter, non comparative open-label, clinical investigation conducted in patients with acute and chronic wounds at risk of local infection or with clinical signs of local infection. this study is carried out in france and spain in around 30 investigator sites. a total of 85 patients meeting the eligibility criteria will be included. the patients will be followed for 4 weeks and a total of 5 clinical evaluations will be carried out by the investigating centers. a planimetric survey of the studied wounds is carried out during the initial assessment of the wound (day 0) and at each assessment provided for in the protocol (week 1, week 2, week 3 and week 4).
