Brief Summary

Bleeding remains the leading cause of death in combat, and the literature suggests that tourniquetable hemorrhage is the second leading cause of preventable death, behind non- tourniquetable hemorrhage. Currently, most Western armed forces recommend the use of the tactical tourniquet in combat for the management of tourniquetable hemorrhage. The SOFTT® tourniquet (Tactical Medical Solutions, Anderson) is the tactical tourniquet currently in use by the French armed forces. As the contract will soon come to an end, the question of its renewal arises. The purpose of this study is to compare 4 commercially available tactical tourniquets in healthy volunteers. The hypothesis of the research is that one of the 4 tourniquets compared is faster to set up than the others.

Outcome Measures

Primary Outcomes (1)

  • Time required to apply the tactical tourniquet.

    The tourniquet application time, in seconds, measured with a stopwatch. The stopwatch will be started when the fitter takes the tourniquet, pre-positioned in a tourniquet pouch on his bullet vest. The stopwatch will be stopped as soon as at least one of the following conditions is verified * the fitter judges the fitting to be effective * the fitter cannot tighten any more (technical limit) * the tourniquet is too painful for the receiver.

    Each day during 4 consecutive days

Secondary Outcomes (5)

  • Occlusion of the downstream arterial flow following after tactical tourniquet application

    Each day during 4 consecutive days

  • Ease of use of the tactical tourniquet

    Each day during 4 consecutive days

  • Rusticity of the tactical tourniquet

    Each day during 4 consecutive days

  • Stability of the tactical tourniquet

    Each day during 4 consecutive days

  • Pain experienced by the receiver during application of the tactical tourniquet

    Each day during 4 consecutive days
