[The use of essential fatty acids in the treatments of wounds].

In spite of being widely spread throughout Brazil, the use of essential fatty acids (EFA) for wound healing is controversial. This study aimed at identifying and analyzing the available scientific evidence for EFA to be used in the treatment of wounds. This is a descriptive study, carried out through a systematic literature review, concerning the Biblioteca Virtual de Saúde (Health Online Library) and PubMed data bank, from 1970 to 2006. Initially, we identified 503 references. After the relevance tests I and II, 11 articles were included in the analysis, showing evidence of recommendation- level II and III for EFA to be used in burns, mediastinitis, among others situations. Most studies still refer to its use in animal. Relevant publications are still scarce.
