Background: While the military use of tourniquets and hemostatic gauze is well established, few data exist regarding civilian emergency medical services (EMS) systems experience.
Methods: A retrospective review was performed of consecutive patients with prehospital tourniquet and hemostatic gauze application in a single ground and rotor-wing rural medical transport service. Standard EMS registry data were reviewed for each case.
Results: During the study period, which included 203,301 Gold Cross Ambulance and 8,987 Mayo One Transport records, 125 patients were treated with tourniquets and/or hemostatic gauze in the prehospital setting. Specifically, 77 tourniquets were used for 73 patients and 62 hemostatic dressings were applied to 52 patients. Seven patients required both interventions. Mechanisms of injury (MOIs) for tourniquet use were blunt trauma (50%), penetrating wounds (43%), and uncontrolled hemodialysis fistula bleeding (7%). Tourniquet placement was equitably distributed between upper and lower extremities, as well as proximal and distal locations. Mean tourniquet time was 27 minutes, with 98.7% success. Hemostatic bandage MOIs were blunt trauma (50%), penetrating wounds (35%), and other MOIs (15%). Hemostatic bandage application was head and neck (50%), extremities (36%), and torso (14%), with a 95% success rate. Training for both interventions was computer-based and hands-on, with maintained proficiency of %gt;95% after 2 years.
Conclusion: Civilian prehospital use of tourniquets and hemostatic gauze is feasible and effective at achieving hemostasis. Online and practical training programs result in proficiency of skills, which can be maintained despite infrequent use.

Non-compressible hemostasis and promoting tissue healing are important in soft tissue trauma repair. Inorganic aerogels show superior performance in rapid hemostasis or promoting tissue healing, but simultaneously promoting non-compressive hemostasis and soft tissue healing still remains a challenge. Herein, SiO-based inorganic nanofiber aerogels (M@SiO, M=Ca, Mg, and Sr) were prepared by freeze-drying the mixture of bioactive silicates-deposited SiO nanofibers and SiO sol.

Rapid control of hemorrhage is vital in first-aid and surgery. As representative of emergency hemostatic materials, inorganic porous materials achieve rapid hemostasis through concentrating protein coagulation factors by water adsorption to accelerate the coagulation reaction process, however their efficacy is often limited by the insufficient contact of material with blood and the lack of blood clot strength. Herein, we report an ultrafast dispersing and in situ gelation sponge (SG/DB) based on anchoring interface effect for hemorrhage control using freeze drying method after mixing fish scale gel (SG) and tert-butyl alcohol (TBA) pre-crystallized diatom biosilica (DB).

The development of self-elastic sponges with enhanced hemostatic and antibacterial properties to treat noncompressible hemorrhage and facilitate wound healing remains challenging. Herein, we prepared a chitosan sponge reinforced with lauric acid-modified quaternized chitosan (LQC) and attapulgite, features a porous structure, high self-elasticity, and rapid shape recovery. The incorporation of LQC conferred the sponge with an enhanced capacity to promote the adhesion, aggregation, and activation of blood cells, and resistance to infection by Staphylococcus aureus, Escherichia coli, and Methicillin-resistant Staphylococcus aureus; the incorporation of attapulgite enhanced the hydrophilicity and mechanical strength of the sponge, and its ability to activate the intrinsic and extrinsic coagulation pathways.

Powdered collagen is emerging as a promising topical hemostat owing to its adaptability to various wounds, active hemostatic abilities, and biosafety. The reproduction of a bionic structure similar to natural collagen is crucial for effective hemostasis and bioactivity. Additional factors relevant to clinical application include antimicrobial properties, minimal immune response, and straightforward preparation.

Emergency bleeding presents significant challenges such as high blood flow and rapid hemorrhaging. However, many existing hemostatic bandages face limitations, including the uncontrolled release of hemostatic agents, insufficient mechanical strength, poor adhesion, and complex manufacturing processes. To address these limitations, we developed a multifunctional hydrogel bandage for emergency hemostasis using a one-pot synthesis method.
