Randomized Controlled Trial Comparative Study
Evaluation of Two Junctional Tourniquets Used on the Battlefield: Combat Ready Clamp® versus SAM® Junctional Tourniquet.
Junctional hemorrhage (i.e., between the trunk and limbs) are too proximal for a tourniquet and difficult to compress. These hemorrhages are responsible for 20% of preventable deaths by bleeding on the battlefield. The majority of these involve the groin area. Devices allowing a proximal compression for arterial axes have been recently developed. ⋯ The SJT and the CRoC were equally effective. The SJT was faster to apply and preferred by the users. Our study provides objective evidence to the French Tactical Casualty Care Committee for improving junctional hemorrhage treatment.

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.

Contact/allergic dermatitis is frequently treated inappropriately with lower-than-recommended doses or inadequate duration of treatment with oral and intramuscular glucocorticoids. This article highlights a case of dermatitis in a Ranger Assessment and Selection Program student who was improperly treated over 2 weeks with oral steroids after being bit by Cimex lectularius, commonly known as bed bugs. The article also highlights the pitfalls of improper oral steroid dosing and provides reasoning for longer-duration oral steroid treatment.

Environmental exposure of tourniquets has been associated with component damage rates, but the specific type of environmental exposure, such as heat, is unknown. Emergency-tourniquet damage has been associated with malfunction and loss of hemorrhage control, which may risk loss of life during first aid. The purposes of the study are to determine the damage rate of tourniquets exposed to heat and to compare the rate to that of controls. ⋯ Heat exposure was not associated with tourniquet damage, inability to gain hemorrhage control, or inability to stop the distal pulse.
