摘要

Six tourniquets designed for combat application were tested for their ease of use and ability to occlude arterial blood flow to the upper arms and thighs in a repeated measures design. To simulate nighttime desert combat conditions, subjects completed an exercise routine while the tourniquet was immersed in a blood analog solution and rolled in sand. Subjects then applied the tourniquet while they were blindfolded and seated or lying supine. They were able to apply all tourniquets in a reasonable amount of time (range: 24- 204 s). The Quickette exhibited a high mechanical failure rate (30%). All tourniquets except the One-Handed Tourniquet (1-inch width) and Quickette performed reasonably well on arms and legs, with median occlusion efficacious exceeding 70%. Subjective rankings indicated that the Mechanical Advantage Tourniquet, Tourni-Kwik, and Combat Application Tourniquet were preferred over the One-Handed Tourniquet (1- and 2-inch models) and the Quickette. Additional research is recommended to investigate increases in blood flow that might occur with inadequate tourniquet application.
