Dried Plasma - Where Are We and Where Next?

Area of Science:

• Trauma resuscitation
• Hemostatic agents
• Blood product logistics

Background:

• Traumatic hemorrhage is a leading cause of death in military and civilian settings.
• Early hemostatic resuscitation, including red cells and plasma, is critical for survival.
• Prehospital blood transfusion improves outcomes but faces significant logistical hurdles.

Purpose of the Study:

• To review the mechanisms of action and efficacy evaluation of plasma in trauma resuscitation.
• To summarize advancements in dried plasma technologies and their impact on plasma quality.
• To critically appraise existing studies on dried plasma for prehospital use.

Main Methods:

• Literature review of mechanisms of plasma action.
• Summary of plasma efficacy assessment approaches.
• Analysis of plasma drying technologies and quality assessment.
• Critical appraisal of four relevant published studies.

Main Results:

• Dried plasma provides a stable, easily reconstitutable alternative to liquid plasma.
• Advances in drying technology maintain plasma's hemostatic properties.
• Dried plasma addresses logistical challenges for prehospital transfusion.

Conclusions:

• Dried plasma is a viable and pragmatic solution for prehospital hemostatic resuscitation.
• It overcomes storage and transport limitations of liquid plasma.
• Further research and implementation are warranted to improve trauma care outcomes.
