ABSTRACT
Purpose: Negative pressure wound therapy (NPWT) has revolutionized wound care, but its high cost reduces the procedure's availability. To solve the problem, streamlined vacuum dressings systems have been proposed, but the utility of these devices has been poorly studied. The objective of this study was to evaluate a simplified vacuum dressing system model (SVDM). Methods: Randomized clinical trial in which wounds were treated with SVDM compared to a complex occlusive dressing (silver hydrofiber, SHF). The analyzed outcomes were cleaning, presence of granulation tissue, clinical appearance, and indication for surgical closure of wounds. Results: Fifty injuries were treated (25 in each group), most located on lower limbs. SVDM proved to be more effective than SHF in the evaluated outcomes. Wound recalcitrance reduced the effectiveness of the equipment used. Despite its efficacy, complications occurred, the most frequent related to dressing changes: minor bleeding, foam adherence to a wound bed, and pain. Only for bleeding no favorable risk-benefit ratio was found. There were no severe complications, worsening conditions of injuries, or deaths. Conclusions: SVDM proved to be an effective and acceptably safe device for managing studied wounds.

Introduction: Hereditary epidermolysis bullosa (EB) is a rare disorder characterized by cutaneomucous fragility, with formation of blisters during minimal trauma. Treatment consists of clinical and nutritional support and management of pain and skin lesions. Silver hydrofiber (Aquacel Ag®) is a type of carboxymethylcellulose fiber dressing with silver that can be used in selected cases of EB. Objective: To review the literature on the general treatment and management of cutaneous lesions in congenital EB and evaluate the indication and experience of using silver hydrofiber dressing. Methods: The review included original articles and systematic reviews published between 2009 and 2014. We also selected two patients with congenital EB treated at the Plastic Surgery Division of Hospital das Clínicas of the Faculty of Medicine of Ribeirão Preto at the University of São Paulo. Results: There is a shortage of scientific evidence related to the treatment of skin lesions in congenital EB, with most recommendations being based on expert opinions. Hydrofiber is indicated in most consensuses for wounds with some exudation and has been shown to be more absorbent than alginate. In our experience, there was apparent improved control of pain, bleeding, and hypothermia with the use of hydrofiber, which has the advantage of not requiring daily changes and can remain on the wound for up to two weeks. Conclusions: The general and lesion treatments in EB are challenging. Hydrofiber with silver is a treatment option for wounds in hereditary EB, without the need for daily dressing changes.
Introdução: Epidermólise bolhosa (EB) hereditária é uma desordem rara caracterizada pela fragilidade cutaneomucosa, com formação de bolhas ao mínimo trauma. O tratamento consiste em suporte clínico, nutricional, manejo da dor e das lesões cutâneas. A hidrofibra com prata (Aquacel Ag®) é um tipo de curativo de fibra de carboximetilcelulose e prata que pode ser utilizada em casos selecionados de EB. Objetivo: Revisão da literatura sobre o tratamento geral e o manejo das lesões cutâneas na EB congênita, além de avaliar a indicação e experiência usando curativo de hidrofibra com prata. Métodos: A revisão incluiu artigos originais e revisões sistemáticas, publicados entre 2009 e 2014. Selecionamos ainda dois pacientes com EB congênita tratados na Divisão de Cirurgia Plástica do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo. Resultados: Há escassez de evidências científicas relacionadas ao tratamento das lesões cutâneas na EB congênita, sendo a maioria das recomendações baseadas em opiniões de especialistas. A hidrofibra está indicada na maioria dos consensos para feridas com alguma exsudação e mostrou-se mais absorvente que o alginato. Em nossa experiência, houve aparente melhor controle da dor, do sangramento e da hipotermia com o uso da hidrofibra, que apresenta a vantagem de não necessitar de trocas diárias, podendo permanecer na ferida por até duas semanas. Conclusões: O tratamento geral e das lesões na EB é um desafio. A hidrofibra com prata é uma opção de tratamento para as feridas na EB hereditária, sem necessidade de trocas diárias de curativo.
