Previous research has shown that external hemorrhage from proximal leg amputations and junctional sites represents 19.2% of potentially survivable lethal hemorrhage. A recent effort to address this problem has resulted in the development of various junctional tourniquets. This study assessed and compared two Tactical Combat Casualty Care Committee-approved junctional tourniquets, the Combat Ready Clamp (CRoC) and the Junctional Emergency Treatment Tool (JETT), to contribute to their future development and to better inform on the decisions for device selection by military units. Aims of the study also were to provide concrete feedback and suggestions on how to effectively apply the devices. ⋯ Even though the JETT might be preferred by military medical providers, the CRoC still has merits. As both devices proved to occlude the arterial flow in no less than 54 seconds on average, they could be used to supplement direct pressure and wound packing, the latter two still being considered the immediate actions for inguinal bleeding control. Considering that the CRoC and the JETT can be applied in as little as 37 and 29 seconds, respectively, users should be effectively trained and entirely proficient on either device to justify their election as the primary countermeasure to hemorrhage not amenable to regular tourniquets.
