Plasma rico em plaquetas e o processo de reparação tecidual em feridas crônicas

Abstract

Objective: To verify the topical use of platelet-rich plasma in the tissue repair process of chronic wounds. Method: narrative review in the Scielo, Lilacs and Medline databases through controlled health descriptors. The search resulted in the selection of a sample made up of 10 studies, according to inclusion and exclusion criteria. Results: It was evident that scarcity of research that addresses the theme and discrepancy between studies found, since some claim that platelet-rich plasma is effective and others report that there is no clinical efficacy. As a result, it can be concluded that these false negatives may occur because they do not have a specific protocol for obtaining platelet-rich plasma, which may alter the concentration of platelets. Conclusion: There is a need for more studies with a sample and longer observation time, as well as to see the need to establish a procurement protocol that must be followed in all surveys.
