Experience from recent conflicts underlines the dramatic impact of effective tourniquet use on combat casualty mortality. Although the Combat Application Tourniquet (CAT) is replacing the silicone band tourniquets (IST; "Israeli Silicone Tourniquet") in the Israeli Defense Forces, no direct comparison was made between them. The purpose of this study is to compare the performance of the two tourniquets on a mid-thigh model.
Participants were Israeli military recruits who previously had the military first aid course. Each participant applied both the CAT and the IST. Applications were assessed by the HapMed Leg Tourniquet Trainer, which measured the applied pressure and the time required to reach it.
IST application resulted in higher rates of effective occlusion pressure compared with the CAT (91% vs. 73.1%, p < 0.01), and a higher mean occlusion pressure (41 mmHg, p < 0.01) was recorded using the IST. Among effective attempts, application time did not differ significantly between the tourniquets.
The IST was superior to the CAT in producing effective occlusion pressure while not prolonging application time. These results may indicate that the IST remains a valid option for controlling mid-thigh bleeding.
近期冲突的经验凸显了有效使用止血带对战斗伤亡人员死亡率的巨大影响。尽管战斗应用止血带（CAT）正在以色列国防军中取代硅胶带止血带（IST；“以色列硅胶止血带”），但尚未对它们进行直接比较。本研究的目的是在大腿中部模型上比较这两种止血带的性能。
参与者为之前参加过军事急救课程的以色列新兵。每位参与者都使用了CAT和IST。应用情况由HapMed腿部止血带训练器进行评估，该训练器测量施加的压力以及达到该压力所需的时间。
与CAT相比，IST应用导致有效闭塞压力的发生率更高（91%对73.1%，p<0.01），并且使用IST记录到更高的平均闭塞压力（41 mmHg，p<0.01）。在有效尝试中，两种止血带的应用时间没有显著差异。
在产生有效闭塞压力且不延长应用时间方面，IST优于CAT。这些结果可能表明IST仍然是控制大腿中部出血的有效选择。
