By means of a descriptive, non-comparative study of a series of clinical cases, the authors analyze the behavior of a dressing of pure calcic-sodium alginate with a stabilizing network in the treatment of pressure sores and profusely bleeding and/or infected vascular uclers. Based on the results of their studies, the authors confirm the effectiveness of this dressing under these conditions: no adverse reactions; the shrinking of the lesion in area or degree of severity; if there is tissue debridement accompanied by sloughing and necrotic tissue, the elimination of infection; ease of application and the reduction of the lesions; use as part of a non-daily cure treatment plan.
