Recent Trends in the Application of Cellulose-Based Hemostatic and Wound Healing Dressings

Rapid hemostasis and wound healing are crucial severe trauma treatment. Natural mechanisms often prove insufficient, spurring research for innovative biomaterials. This review focuses on cellulose-based materials, which are promising due to their absorbency, biocompatibility, and processability. The novelty lies in exploring how these materials promote clotting and tissue regeneration. They operate via extrinsic and intrinsic mechanisms. Extrinsically, they create a matrix at the wound to activate coagulation; intrinsically, they maintain clotting factors. Additionally, they aid healing through physical, chemical, and biological means, such as maintaining moisture, incorporating antimicrobial agents, and stimulating cell activity. The innovative fabrication strategies include material selection and chemical modification. Techniques like oxidation enhance performance. Structural engineering methods like freeze-drying and 3D printing optimize porosity and alignment. Cellulose-based dressings are versatile and effective in various forms. They address different wound needs and show benefits like rapid coagulation and tissue repair. This review also covers challenges and future trends, emphasizing the need to enhance mechanical properties and biodegradability. Further, new technologies offer potential improvements to the nanocomposites. Overall, continued research on cellulose-based dressing is vital, and unlocking their potential could revolutionize wound care, providing suitable solutions for trauma management.
