Advances in Topical Hemostatic Agent Therapies: A Comprehensive Update

Area of Science:

• Biomedical Engineering
• Materials Science
• Emergency Medicine

Background:

• Severe hemorrhage leads to metabolic and cellular dysfunction due to poor tissue perfusion and oxygen delivery.
• Uncontrolled bleeding can result in hemodynamic instability, hypoxemia, multiple organ failure, and death.

Purpose of the Study:

• To review currently available and developing topical hemostatic materials.
• To discuss the clinical applications of these agents in achieving hemostasis.

Main Methods:

• Review of existing literature on hemostatic agents.
• Categorization of agents into topical active agents, mechanical agents, synthetic/hemisynthetic agents, and external hemostatic dressings.

Main Results:

• Various hemostatic techniques exist, including surgical methods, chemical agents, nanoparticles, and physical pressure.
• Topically-applied hemostatic agents offer significant clinical applications.
• Emerging hemostatic materials are becoming more targeted due to a better understanding of the clotting cascade.

Conclusions:

• Topical hemostatic agents are crucial for managing severe bleeding.
• A range of materials, from traditional to advanced, are available and under development.
• Continued research aims to enhance the efficacy and targeting of hemostatic agents for improved patient outcomes.
