“…Even though various scholars have executed ET application studies, most of these have been conducted in laboratory settings or at ambient temperatures. [24][25][26][27][28][29] The Antarctic field conditions of humidity levels, windchill impact, Zodiac movements, and cold weather conditions present a considerable obstacle when striving to replicate experimental outcomes. 22,23 Despite these challenges, the participants could SA most of the ET in the upper and lower extremities donned in the AES.…”

Search and rescue teams and Antarctic research groups use protective cold-water anti-exposure suits (AES) when cruising on Zodiacs. Extremity tourniquet (ET) self-application (SA) donned with AESs has not been previously studied. Our study therefore assessed the SA of 5 commercial ETs (CAT, OMNA, RATS, RMT, and SWAT-T) among 15 volunteers who donned these suits. Tourniquet‘s SA ability, ease of SA, tolerance, and tourniquet preference were measured. All ETs tested were self-applied to the upper extremity except for the SWAT, which was self-applied with the rest to the lower extremity. Ease- of- SA mean values were compared using the Friedman and Durbin-Conover post hoc tests (P < 0.001). Regarding the upper extremity, OMNA achieved the highest score of 8.5 out of 10, while RMT, and SWAT received lower scores than other options (P < 0.001). For lower extremities, SWAT was found to be inferior to other options (P < 0.01). Overall, OMNA was the best performer. The RATS showed significantly lower tolerance than the other groups in repeated- measures ANOVA with a Tukey post hoc test (P < 0.01). Additionally, out of the 5 ETs tested, 60% of subjects preferred OMNA. The study concluded that SA commercial ETs are feasible over cold-water anti-exposure suits in the Antarctic climate.

“…The CATwas modified to incorporate a single routing buckle and thicker windlass. 9 Meanwhile, the SOFTT-W underwent changes to include an increased strap width, the removal of a windlass D-ring and locking screw, and the addition of a tourniquet retention assistance clip (TRAC). Finally, the TMT is a newer tourniquet and differs from the previous two tourniquets by the addition of a dual locking mechanism if the velcro fails.…”

BACKGROUND:Exsanguination due to extremity hemorrhage is a major cause of preventable traumatic deaths. Extremity tourniquet use has been shown to be safe and improve survival. The purpose of this study was to compare the efficacy, efficiency, and durability of the Generation 7 Combat Application Tourniquet (CAT; North American Rescue, Greer, SC), the Tactical Mechanical Tourniquet (TMT; Combat Medical Systems, Harrisburg, NC), and the SOF Tactical Tourniquet-Wide (SOFTT-W; Tactical Medical Solutions, Anderson, SC). METHODS:This study was a three-phase randomized, cross-over trial. In successive trials, subjects were timed during the application of each tourniquet to the upper and lower extremity. Following successful lower extremity application, subjects low crawled 25 ft and then were dragged 25 ft, after which effectiveness was reassessed, as defined by the cessation of distal pulses by Doppler ultrasound. RESULTS:In arm application, both the CAT and TMT had significantly less failure rates than the SOFTT-W (5.56%, 19.44%, 58.33%), with the CAT being the fastest tourniquet when compared with TMT and SOFTT-W (37.8 seconds, 65.01 seconds, 63.07 seconds). In leg application, the CAT had significantly less rates of failure when compared with the SOFTT-W, but there was no other significant difference between the tourniquets (27.78%, 44.44%, 61.11%). In addition, the CAT was significantly faster than both the TMT and SOFTT-W when applied to the leg (8.33 seconds, 40.96 seconds, 34.5 seconds). There was no significant difference in tourniquet failure rates between the three tourniquets after subject maneuvers in phase 3 (34.29%, 42.86%, 45.45%). DISCUSSION:The CAT is as effective as the TMT and significantly more effective than the SOFTT-W. In addition, the CAT demonstrated shorter application times than either the TMT or SOFTT-W. However, there was no significant difference between the three tourniquets in their ability to maintain pulselessness after subject maneuvers.

Prähospitale Anwendung von Tourniquets bei lebensbedrohlichen Extremitätenblutungen

The 50 original articles included in this qualitative, systematic review revealed that the recommendations "Tourniquet" of the DGAI published in 2016 are mostly still up to date despite an inhomogeneous study situation. A deviation occurred in the conversion of a tourniquet but due to the short prehospital treatment time in the civilian setting this is of little importance; however, in the future a strict distinction should be made between tourniquets which were placed for tactical reasons and those placed as a medical necessity.
