Comparative Study
Testing of Junctional Tourniquets by Medics of the Israeli Defense Force in Control of Simulated Groin Hemorrhage.
Junctional hemorrhage is a common cause of battlefield death but little is known about testing of junctional tourniquet models by medics. The purpose of the testing described herein is to assess military experience in junctional tourniquet use in simulated prehospital care. ⋯ In the five assessment categories, multiple tourniquet models performed similarly well; SJT and AAJT performed best in four categories, JETT was best in three, and CRoC was best in two. Differences between the top-ranked models in each category were not statistically significant.

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.

Management of critically ill patients in austere environments is a logistic challenge. Availability of oxygen cylinders for the mechanically ventilated patient may be difficult in such a context. One solution is to use a ventilator able to function with an oxygen concentrator (OC). ⋯ OCs provide an alternative to oxygen cylinders for delivering high Fio2 with a turbine ventilator. Nevertheless, Fio2 must be monitored continuously, since it decreases when minute ventilation is increased.

Comparative Study
Preliminary Comparison of Pneumatic Models of Tourniquet for Prehospital Control of Limb Bleeding in a Manikin Model.
Emergency tourniquet use has been associated with hemorrhage control and improved survival during the wars since 2001, but little is known of the differential performance of pneumatic tourniquet models. The purpose of this study was to compare the performance of three models of pneumatic tourniquets in a laboratory setting to aid a possible decision to field test suitable models for medic preference. ⋯ All models of tourniquet performed equally well for both the critical outcome of effectiveness and the important outcome of pulse stoppage, whereas results for secondary outcomes (time, pressure, and blood loss) differed by model. The EMT had best performance for every type of measurement.
