Enquadramento: A resposta fibroblástica às úlceras por pressão é prejudicada pela
depleção de proteínas e energia, resultando numa cicatrização mais lenta. Além das
proteínas, algumas vitaminas e sais minerais exercem papel importante no processo de
cicatrização como a vitamina A (ácido ascórbico), vitaminas do complexo B, ferro, cobre,
zinco e o magnésio.
Objetivo: Verificar os benefícios do suplemento de zinco e ácido ascórbico no tratamento da
úlcera por pressão.
Métodos: Foi realizada uma revisão sistemática da literatura sobre os benefícios do
suplemento de zinco e ácido ascórbico no tratamento da úlcera por pressão. Efetuou-se uma
pesquisa na EBSCO, Pubmed, The Cochrane Library, Scielo e Google Académico de
estudos publicados entre de janeiro de 2008 a abril de 2017, partindo dos critérios de
inclusão precedentemente definidos, os estudos selecionados foram depois avaliados.
Resultados: Os estudos analisados confirmam que os resultados de cicatrização da úlcera
por pressão apresentam a vitamina C e o zinco de modo combinado nas composições das
fórmulas e não isoladamente. O suplemento de doses elevadas de vitamina C tem-se
revelado como um coadjuvante na cicatrização das úlceras por pressão. Contudo, ainda há a
necessidade de se realizarem estudos que comprovem uma eficácia do suplemento isolado
de vitamina C e zinco no tratamento de doentes com úlcera por pressão.
Conclusão: Os resultados sugerem que se desenvolva um plano individualizado de
cuidados nutricionais para os doentes em risco de desenvolver ou com úlceras por pressão
ou para os que já tenham úlceras por pressão.

Abstract Background: Fibroblast response to pressure ulcers is impaired by protein and energy depletion, resulting in slower healing. In addition to proteins, some vitamins and minerals play an important role in the healing process, such as vitamin A (ascorbic acid), B vitamins, iron, copper, zinc and magnesium. Objective: To verify the benefits of zinc and ascorbic acid supplementation in the treatment of pressure ulcer. Methods: A systematic review of the literature on the benefits of zinc and ascorbic acid supplementation in the treatment of pressure ulcer was performed. A search was conducted in the EBSCO, Pubmed, The Cochrane Library, Scielo and Google Scholar studies published between January 2008 and April 2017, based on the inclusion criteria previously defined, the selected studies were then evaluated. Results: The studies analyzed confirm that the results of healing of pressure ulcer present vitamin C and zinc in combination in the compositions of the formulas and not alone. Supplementation of high doses of vitamin C has been shown as a coadjuvant in the healing of pressure ulcers. However, there is still a need for studies demonstrating efficacy of the isolated supplement of vitamin C and zinc in the treatment of patients with pressure ulcer. Conclusion: The results suggest that an individualized nutritional care plan should be developed for patients at risk of developing or having pressure ulcers or those who already have pressure ulcers. Keywords: Pressure ulcer; Zinc supplement; Ascorbic acid (vitamin C).
