External Hemorrhage Control Techniques for Human Space Exploration: Lessons from the Battlefield.

Area of Science:

• Aerospace Medicine
• Trauma Care
• Emergency Medicine

Background:

• Military medicine has significantly improved prehospital trauma care, emphasizing early hemorrhage control.
• Space exploration presents unique challenges for trauma management, including environmental hazards and physiological adaptations to microgravity.

Purpose of the Study:

• To review external hemorrhage control techniques.
• To assess the applicability of military trauma care concepts in space exploration.
• To identify strategies for managing traumatic bleeding in space missions.

Main Methods:

• Narrative literature review.
• Analysis of military prehospital trauma care advancements.
• Evaluation of space environment factors impacting trauma care.

Main Results:

• Early hemorrhage control is critical in space due to delayed care and physiological changes.
• Tourniquets and hemostatic dressings appear feasible but require adequate training.
• Tranexamic acid and advanced techniques show promise for space trauma management.

Conclusions:

• Military hemorrhage control strategies can be adapted for space exploration.
• Training and appropriate tools are essential for managing bleeding in space.
• Future missions require robust protocols for point-of-injury hemorrhage control.
