| Abstract | Background: Bleeding remains the leading cause of potentially preventable deaths both in military and civilian pre-hospital trauma settings. Conventional extremity tourniquets do not control bleeding if an iliac artery or a common femoral artery is injured. Stopping junctional bleeding is particularly challenging and requires the use of specifically designed junctional tourniquets. SAM® Junctional Tourniquet (SJT®, United States of America) and Tactical Abdominal Junctional Tourniquet (T-AJT®, Fora Group Türkiye) have been actively used by Turkish security forces. This study questioned the effect of training on combat medics' successful junctional tourniquet applications and application times (AT). Methods: Our research on two different junctional tourniquet models was designed as a prospective randomized, crossover, single-blinded study. All 40 participants in the study were attendees of a 12-week combat medic training course with updated medical approvals, which were used as an eligibility criterion. Randomization was performed by drawing T-AJT®-SJT cards. The study consisted of pretraining and after-training tourniquet application phases. In each study phase, all participants' AT and the presence or absence of arterial flow were recorded for each group. Finally, the combat medics were presented with a 6-question survey. Results: Although training increased successful T-AJT® application rates, training was not statistically significantly associated with successful applications for any tourniquet types (p>0.05). The pretraining phase ATs for SJT® and T-AJT® were 55±11.8 and 93.8±2.9 seconds, respectively, and the difference was statistically significantly different (p<0.001). Likewise, after-training phase ATs for SJT® and T-AJT® were 49±22.6 and 79.2±17.5 seconds, respectively, and participants' SJT® ATs were significantly shorter (p<0.001). Overall, when participants' applied any of the tourniquet unsuccessfully, the odds of participants' lower Visual Analogue Scale scores were 0.2 (95% CI [0.08, 0.49]. p<0.001). Conclusion: Our study basically investigates the effects of training on effective tourniquet application. Unfortunately, our after-training success rates remained unsatisfactory when compared to other studies. This is also the first study on T-AJT® tourniquet application, and further studies on its efficacy are also required. |
