Research status and development potential of composite hemostatic materials

Area of Science:

• Biomaterials Science
• Hemostasis Research
• Wound Healing

Background:

• Bleeding is a critical medical issue requiring effective hemostasis for survival and wound healing.
• Current hemostatic materials activate coagulation through physical barriers, platelet aggregation, or clotting factor release.
• There is a need for advanced hemostatic materials with improved properties.

Purpose of the Study:

• To review the current state of composite hemostatic materials.
• To discuss mechanisms of action for hemostatic materials.
• To propose future directions for the development of advanced hemostatic materials.

Main Methods:

• Literature review of composite hemostatic materials.
• Analysis of coagulation mechanisms activated by hemostatic agents.
• Discussion of material characteristics and their impact on hemostasis.

Main Results:

• Composite hemostatic materials offer enhanced efficacy by activating multiple coagulation pathways.
• Existing materials often lack ideal characteristics such as biocompatibility, shape adaptability, and in vivo degradability.
• Simultaneous activation of various clotting mechanisms is key to superior hemostatic performance.

Conclusions:

• Future composite hemostatic materials should prioritize high biocompatibility, shape variability, and in vivo degradability.
• Materials capable of addressing both internal and external bleeding are desirable.
• Further research into camouflaging properties and clotting factor release is recommended for optimized hemostatic materials.
