Water triggered injectable polylactic acid hydrogel based on zwitterionic sulfobetaine modification for incompressible bleeding and tissue anti-adhesion
Massive blood loss is the main cause of prehospital trauma-related death, the development of rapid and effective hemostatic materials is imminent.Injectable hydrogels have the advantages of covering irregular bleeding sites and quickly closing the wound.However, its inherent viscosity can easily precipitate tissue adhesion in vivo and other complic
