Plasma rico em plaquetas no tratamento de feridas de difícil cicatrização: revisão de escopo

Abstract

Objective: To map the scientific evidence generated by the nursing profession regarding the use of platelet-rich plasma (PRP) in the healing of hard-to-heal wounds. Method: A scoping review was conducted in the Scopus, Web of Science, PubMed, and Cochrane databases, supplemented by a search for gray literature via Google Scholar. Study selection was conducted according to inclusion criteria and the PCC strategy, followed by a critical review of the evidence, presentation of the results in a flowchart, and a narrative synthesis of the findings. Results: Venous ulcers were the primary conditions treated with PRP, with gel being the most common form of application. Among the observed benefits were a reduction in wound size, decreased pain, and improved granulation tissue quality, possibly associated with the action of growth factors present in PRP. Limitations included the absence of standardized protocols, costs associated with the therapy, and the longer time required for its application. Conclusion: PRP shows potential as an alternative for the treatment of chronic wounds; however, further studies are needed to strengthen the evidence regarding its efficacy.
