Development of coverage and its evaluation in the treatment of chronic wounds/Desarrollo de cobertura y su evaluacion en el tratamiento de las heridas cronicas/Desenvolvimento de cobertura e sua avaliacao no tratamento de feridas cronicas

Objective. To describe the development of the bacterial cellulose coating with anti-inflammatory Ibuprofen (BC/ Ibu) and to evaluate the cicatrization process with its use in patients with chronic wounds of venous and diabetic etiology. Methods. Longitudinal descriptive study. The cellulose membrane, cultivated with bacteria Gluconacetobacter xylinus and with incorporation of Ibuprofen, was used in the treatment of patients with chronic wounds in public health services in a Brazilian municipality. The ideal coverage characteristics were evaluated through physical, chemical and cell proliferation tests. Results. The sample consisted of 14 patients (10 women and 4 men), 8 with venous ulcer, 5 with diabetic foot and one with mixed wound. There was reduction of area and pain in 9 lesions; total healing of 3 wounds; and debridement of the devitalized tissue in 5 wounds with increased area. The use of the membrane was important in the reduction of pain, exudation and ease in the accomplishment of the curative. Conclusion. BC/Ibu favored the cicatrization process of patients with chronic vasculogenic wounds. Descriptors: diabetic foot; varicose ulcer; cellulose; ibuprofen; wound healing; Gluconacetobacter xylinus. Objetivo. Describir el desarrollo de la cobertura de celulosa bacteriana con antiinflamatorio Ibuprofeno (CB/ Ibu) y evaluar el proceso de cicatrizacion en la utilizacion en pacientes con heridas cronicas de etiologia venosa y diabetica. Metodos. Estudio descriptivo longitudinal. La membrana de celulosa, cultivada con bacterias Gluconacetobacter xylinus y con incorporacion del Ibuprofeno se utilizo en el tratamiento de pacientes con heridas cronicas en servicios de atencion publica de un municipio brasileno. Se evaluaron caracteristicas de cobertura ideal mediante pruebas fisicas, quimicas y de proliferacion celular. Resultados. La muestra fue constituida por 14 pacientes (10 mujeres y 4 hombres): 8 con ulcera venosa, 5 con pie diabetico y uno con herida mixta. Se redujo el area y el dolor en 9 lesiones; la cicatrizacion total de 3 heridas; y el debridamiento del tejido desvitalizado en 5 heridas con aumento del area. El uso de la membrana de celulosa disminuyo el dolor de la exudacion y facilito la realizacion del vendaje. Conclusion. La CB/Ibu favorecio el proceso de cicatrizacion de los pacientes con heridas cronicas vasculogenicas.
