Effective nonelastic strap-based tourniquets are typically pulled tight and friction or hook-and-loop secured before engaging a mechanical advantage system to reach arterial occlusion pressure. This study examined the effects of skin surface initial secured pressure (Friction Pressure) on the skin surface pressure applied at arterial occlusion (Occlusion Pressure) and on the use of the mechanical advantage system. ⋯ Achieving high initial strap tension is desirable to minimize windlass turns or ratcheting buckle travel distance required to reach arterial occlusion, but does not affect tourniquet surface-applied pressure needed for arterial occlusion. For same-width, nonelastic strap-based tourniquets, differences in the mechanical advantage system may be unimportant to final tourniquet-applied pressure needed for arterial occlusion.

Comparative Study
Testing Tourniquet Use in a Manikin Model: Two Improvised Techniques.
Improvised tourniquets may be used to treat limb wound hemorrhage, but there is little evidence for best techniques of use. The purpose of the present study is to compare use of two techniques of improvised tourniquet application and use of a common commercial tourniquet that is nonimprovised. ⋯ In the present experiment, the commercial CAT performed better than either improvised tourniquet.

The purpose of this study was to compare the effectiveness of QuikClot(®) Combat Gauze™ (QCG) to a control wound dressing to withstand movement in a porcine model with hemodilution and hypothermia. ⋯ QCG produces a robust clot that can withstand more movement than a control dressing.

Active violent incidents are dynamic and challenging situations that can produce a significant amount of preventable deaths. Lessons learned from the military?s experience in Afghanistan and Iraq through the Committee on Tactical Combat Casualty Care and the 75th Ranger Regiment?s Ranger First Responder Program have helped create the Committee for Tactical Emergency Casualty Care (C-TECC) to address the uniqueness of similar wounding patterns and to end preventable deaths. We propose a whole-community approach to active violent incidents, using the C-TECC Trauma Chain of Survival and a tiered approach for training and responsibilities: the first care provider, nonmedical professional first responders, medical first responders, and physicians and trauma surgeons. The different tiers are critical early links in the Chain of Survival and this approach will have a significant impact on active violent incidents.
