Delivering medical care in nighttime conditions is challenging, as 25% of Special Operations medical Operators have reported that problems with lighting contributed to poor casualty outcomes. Red light is often used in nighttime operations but makes blood detection difficult and diminishes depth perception and visual acuity. Red-green combination lighting may be superior for differentiating blood from tissue and other fluids but had not been tested versus red-only or green-only lighting for combat-related medical procedures, such as wound suturing.

Dark-adapted medical resident physicians (N = 24) sutured 6cm long, 3cm deep, full-thickness lacerations in deceased swine under red-only, green-only, and red-green lighting provided by a tactical flashlight using a randomized within-subjects design. Time to suture completion, suture quality, user ratings, and user preference data were contrasted at p < .05. This study was approved by Naval Medical Center Portsmouth IRB.

Suture completion time and suture quality were similar across all lighting conditions. Participants rated red-green lighting as significantly easier for identifying blood, identifying instruments, and performing suturing (p < .01). Red-green lighting was preferred by 83% of participants compared to 8% each for red-only and green-only (p < .001).

Pending further study under tactical conditions, red-green lighting is tentatively recommended for treating battlefield wounds in low-light environments.

EMS personnel are often exposed to traumatic material during their duties. It is unknown how prior military experience affects the presence of stress in EMS personnel.

This was a prospective cross-sectional study. Nine EMS agencies provided data on call mix, while individuals were recruited during training evolutions. The survey evaluated sociodemographic factors and the relationship between childhood trauma and previous military service using the Adverse Childhood Experiences questionnaire, Life Events Checklist DSM-5, and Military History Questionnaire. Descriptive statistics calculated personal trauma profiles, comparing civilian EMS personnel to those with prior service. Hierarchical linear regression assessed the predictive utility of military history to scores on the Impact of Events Scale-Revised.

A total of 765 EMS personnel participated in the study; 52.8% were male, 11.4% were minorities, and 11.6% had prior military service. A total of 64.4% of civilian EMS providers had any stress syndrome, while that number was 71.8% in those with prior military service. Hierarchical linear regression identified that years of service and the performance of combat patrols or other dangerous duty accounted for a unique criterion variance in the regression model.

Prior military service or combat deployments alone do not contribute to the presence of stress syndromes. However, performance of combat patrols or other dangerous duties while deployed was a contributing factor. These results must be interpreted holistically, as other factors contribute to the presence of vicarious trauma (VT) in EMS personnel who are also veterans.

The utility of prehospital thoracic needle decompression (ND) for tension physiology in the civilian setting continues to be debated. We attempted to provide objective evidence for clinical improvement when ND is performed and determine whether technical success is associated with provider factors. We also attempted to determine whether certain clinical scenarios are more predictive than others of successful improvement in symptoms when ND is performed.

Prehospital ND data acquired from one air ambulance service serving 79 trauma centers consisted of 143 patients (n = 143; ND attempts = 172). Demographic and clinical outcome data were retrospectively reviewed. Patients were stratified by prehospital characteristics and indications. Objective outcomes were measured as improvement in vital signs, subjective patient assessment, and physical examination findings. Univariate analysis was performed using chi-square for variable proportions and unpaired Student's t-test for variable means; p < .05 was consideg. Outcomes are less reliable in cases of cardiopulmonary arrest or hypotension with respiratory symptoms; however, this should not deter prehospital providers from attempting ND when clinically indicated. Additionally, the success rate of prehospital ND does not appear to be related to catheter type or the role of the performing provider.Uncontrolled hemorrhage secondary to unstable pelvic fractures is a preventable cause of prehospital death in the military and civilian sectors. Because the mortality rate associated with unstable pelvic ring injuries exceeds 50%, the use of external compression devices for associated hemorrhage control is paramount. During mass casualty incidents and in austere settings, the need for multiple external compression devices may arise. In assessing the efficacy of these devices, the magnitude of applied force has been offered as a surrogate measure of pubic symphysis diastasis reduction and subsequent hemostasis. This study offers a sensor-circuit assessment of applied force for a convenience sample of pelvic compression devices. The SAM® (structural aluminum malleable) Pelvic Sling II (SAM Medical) and improvised compression devices, including a SAM Splint tightened by a Combat Application Tourniquet® (C-A-T; North American Rescue) and a SAM® Splint tightened by a cravat, as well as two joined cravats and a standard-issue military belt, were assessed in male and female subjects. As hypothesized, compressive forces applied to the pelvis did not vary significantly based on device operator, subject sex, and subject body fat percentage. The use of the military belt as an improvised method to obtain pelvic stabilization is not advised.

In the French army, combat casualty care (CCC) training involves the use of simulation. The application of this pedagogic method in a cross-cultural environment has not previously been described. In this report, we explore the challenges highlighted by multiple training sessions for foreign medical providers in West Africa.

We collected the data from six 2-week courses held in Libreville, Gabon. Our main objective was to describe the course; our secondary objective was to assess our trainees' progress in their knowledge of CCC.

The first week involved lectures, technical workshops, and single-patient simulations. The second part emphasized multiple-victim simulations and interactions with combatants and was held in the Gabonese rainforest. Sixty- two trainees undertook the six sessions. Their knowledge improved during the course, from a median score of 4 (of a maximum of 40) before to 9.5 after (p < .05).

Our study is the first to describe medical-level CCC training in a cross-cultural environment. Challenges are numerous, notably differences in the expected roles of instructors and trainees. Mitigating those difficulties is possible through cultural awareness and self-awareness. selleck chemicals llc Our results are limited by the absence of evaluation of improvement in the actual management of patients.

CCC training using medical simulation is feasible in a cross-cultural environment.

Sterilization of healthcare instruments in an expeditionary environment presents a myriad of challenges including portability, cost, and sufficient electrical power. Using pressure cookers to sterilize instruments presents a low-cost option for sterilization in prehospital settings. This project's objective was to determine if sterility can be achieved using a commercially available pressure cooker.

Presto® 4-quart stainless steel pressure cookers were heated using Cuisinart® CB-30 cast-iron single burners. One 3M™ Attest™ 1292 Rapid Readout Biological Indicator and one 3M™ Comply™ SteriGage™ integrator strip were sealed in a Henry Schein® Sterilization Pouch and placed in a pressure cooker and brought to a pressure of 103.4kPa. Sterility was verified after 20 minutes at pressure. The Attest vials were incubated in a 3M Attest 290 Auto-Reader for 3 hours with a control vial.

Sterility using the pressure cooker was achieved in all tested bags, integrator strips, and Attest vials (n = 128). The mean time to achieve the necessary 103.4kPa was 379 seconds (standard deviation (SD) = 77). Neither the ambient temperature nor humidity were found to affect the pressure cooker's time to achieve adequate pressure, nor the achieved depth on the integrator strip (all p > .05).

This study provides evidence that sterilization is possible with offthe- shelf pressure cookers. Though lacking US Food and Drug Administration (FDA) approval, the use of this commercially available pressure cooker may provide a method of sterilization requiring minimal resources from providers working in expeditionary environments.

Two methods of controlling pelvic and inguinal hemorrhage are the Abdominal Aortic and Junctional Tourniquet (AAJT; Compression Works) and resuscitative endovascular balloon occlusion of the aorta (REBOA). The AAJT can be applied quickly, but prolonged use may damage the bowel, inhibit ventilation, and obstruct surgical access. REBOA requires technical proficiency but avoids many of the complications associated with the AAJT. Conversion of the AAJT to REBOA would allow for field hemorrhage control with mitigation of the morbidity associated with prolonged AAJT use.

Yorkshire male swine (n = 17; 70-90kg) underwent controlled 40% hemorrhage. Subsequently, AAJT was placed on the abdomen, midline, 2cm superior to the ilium, and inflated. After 1 hour, the animals were allocated to an additional 30 minutes of AAJT inflation (continuous AAJT occlusion [CAO]), REBOA placement with the AAJT inflated (overlapping aortic occlusion [OAO]), or REBOA placement following AAJT removal (sequential aortic occlusion [SAO]). Following removal, animals were observed for 3.5 hours.

No statistically significant differences in survival, blood pressure, or laboratory values were found following intervention. Conversion to REBOA was successful in all animals but one in the OAO group. REBOA placement time was 4.3 ± 2.9 minutes for OAO and 4.1 ± 1.8 minutes for SAO (p = .909). No animal had observable intestinal injury.

Conversion of the AAJT to infrarenal REBOA is practical and effective, but access may be difficult while the AAJT is applied.
