Las bioimpresora al servicio de los pacientes con quemaduras

Abstract

A burn is an injury to the tissues of the body caused by heat, chemicals, electricity, sun, radiation, hot liquid, steam, fire and flammable gases. The burn is the most serious trauma that a living being can suffer. The burned patient is the most complete and complex model of the inflammatory process, where all mediators of inflammation are present, leading to a rupture of homeostasis, leading to multiple organ failure. Burns are classified into three types or grades: first (epidermis), second (superficial and / or deep in the dermis) and third (hypodermis). The most innovative treatments to date: biomaterials derived from blood (platelet-rich plasma is a concentrated blood derivative, generated by a process of centrifugation of whole blood). Stem cells stand out for their capacity for self-regeneration and its asymmetric replication, in each cell division one of the cells maintains capacity for self-regeneration, researchers in Brazil successfully tested using the skin of a freshwater fish called tilapia to cure severe burns (second and third degree), the treatment consists in replacing the bandage and ointment with the skin of the tilapia, leave in the burned area for several days. This will save costs and also pain to the patient that causes the traditional bandage change. Other innovative techniques: enzymatic debridement is a technique that dissolves damaged tissue following severe burn, leaving viable and clean tissue that favors the recovery of healthy skin, significantly reducing grafts and other complex surgeries. The 3D bio-printer capable of creating human skin, 100% functional and in the not too distant future, to be transplanted to patients. Other advantages of these tissues created by the bioprinter, can be used for the testing of pharmaceutical, cosmetic and chemical products of great consumption, where the current regulation requires testing without animals. The methodology used is descriptive, with a documentary approach, that is, to review sources available on the web, such as academic google, with timely, updated and relevant content from a scientific point of view that enriches the analysis of the topic raised in this article.

“…Pesquisadores do Brasil também testaram com sucesso a pele da tilápia, esse peixe de água doce pode curar queimaduras graves (2º e 3º grau), o tratamento consiste em substituir o curativo e a pomada pela pele da tilápia, deixando na área queimada por vários dias. Isso, além de economizar custos, tem o benefício de reduzir a dor para o paciente que faz a troca do curativo (Córdova et al, 2019). Os curativos de pele de tilápia são projetados como biomateriais engenhosos e inovadores, e seu uso acelera a cicatrização de queimaduras, permite uma redução considerável da dor e um resultado mais estético para os pacientes, devido ao seu conteúdo de colágeno e sua aderência ao tecido da pele (Madrigal et al, 2022).…”
