3D-Printed Tourniquets Used at the Battlefront in Ukraine: A Pilot Study
Background:
The war in Ukraine urged a need for prompt deliv- erance and resupply of tourniquets to the front. Producing tour- niquets near the battlefront was a feasible option with respect to resupply and cost.
Methods:
A locally produced 3D-printed tourniquet (Ukrainian model) from the "Tech Against Tanks" charity was tested against commercially available and Committee of Tactical Combat Casualty Care (CoTCCC)- recommended tourniquets (C-A-T™ and SOF™TT-W). We tested how well the tourniquets could hold pressure for up to 2 hours.
Results:
A Kruskal-Wallis test revealed significant differences between the groups (p<.05). Post-hoc testing revealed a signif- icant difference between the C-A-T and the Ukrainian tourni- quet (p=.004). A similar significance was not found between the SOF™TT-W Wide and the Ukrainian model (p=.08). Dis- cussion: The Ukrainian model can hold pressure as well as the commercially available tourniquets. There is much value if this can be produced close to the battlefield. Factors including lo- gistics, cost, and self-sufficiency are important during wartime.
Conclusion:
We found that our sample of 3D-printed tourni- quets, currently used in the war in Ukraine, could maintain pressure as well as the commercially available tourniquets. In- deed, our tests demonstrated that it could maintain a signifi- cantly higher pressure.
