Progress in the research and application of polysaccharide hemostatic materials

Local hemostasis is the first step in wound treatment, and effective hemostatic methods could reduce the number of unnecessary casualties. Hemostatic materials need to have good hemostatic properties, excellent biocompatibility, no toxic side effects, no irritation and easy to prepare. The polysaccharide has many advantages, including rich source, simple structures, absorbable and biodegradable, excellent biocompatibility. At present, it has been found that polysaccharide is easy to modify in structure and recombine. This paper summarizes the characteristics and products of polysaccharide hemostatic materials including celluloses, chitosans, alginate, hyaluronic acid, and starch in order to offer the indications for clinical application and further study.
