Rational design of porous starch/hyaluronic acid composites for hemostasis.

Effective hemorrhage control is pivotal for decreasing the trauma death both in civilian and military but has proven to be dauntingly challenging, especially for solid viscera and artery trauma. Here we report the fabrication of a novel starch-based hemostat, sodium trimethaphosphate (STMP)-crosslinked starch/hyaluronic acid (HA) (ScSH) porous composites. Aiming at hemostatic potential, physicochemical properties, cytocompatibility, hemocompatibility, histocompatibility and hemostatic performance of ScSH composites have been studied.
