[DEVELOPMENT RESEARCH OF BIOLOGICAL DRESSING].

To review the research progress of modern biological dressings.The related literature at home and abroad was reviewed, analyzed, and summarized in the progress of biological dressing situation and various types of biological dressing research.Compared with the traditional dressing, the biological dressing can greatly promote wound healing. Biological dressings are mainly divided into the natural materials, artificial synthetic materials, and drug loaded dressings. The natural material dressings are mainly the alginate dressing, this kind of dressing can promote wound healing, which has been confirmed by a large number of studies. The artificial synthetic materials include film dressings, liquid, water colloids, gels, and foam, each has its own advantages and disadvantages, which can be chosen according to need. The drug dressing can play the role of drug loading, and further promote the wound healing; using microcapsule technology to construct the dressing and choosing Chinese medicine as drugs is the research direction of load.The experiment and clinical application of biological dressing are many types, clinical application prospect is wide, but each has its own advantages and disadvantages, further study is needed to improve its efficacy.
