Moulage is used to create mock wounds and injuries for clinical education and training. We developed a moulage technique to simulate a facial gunshot wound for use in simulation-based training. We removed sections of a manikin’s face and used moulage materials to mock various aspects of the wound. The manikin was used in a simulated scenario that teaches clinicians how to manage a complicated airway. The moulage was evaluated with a self-report questionnaire that assessed participants’ perceptions of the realism of the wound, the degree to which the wound contributed to their scenario immersion, and the degree to which the wound enhanced their learning experience on a 5-point Likert scale ranging from ‘strongly disagree’ to ‘strongly agree’. Participants’ average response to each item was significantly higher than the neutral midpoint, and the median response was ‘strongly agree’. Our work suggests that the simulated facial gunshot wound contributed to perceived scenario immersion and enhancement of the learning experience, supporting existing literature that suggests moulage is a valuable tool in healthcare simulation. Future work could investigate the effect of moulage using objective measures and explore the potential to use extended reality technology in conjunction with moulage to improve immersion even further.

Purpose. To develop a method of high-speed video fixation of a standardized model of gunshot open globe injury type B. Material and methods. The study was divided into several stages. Literature analysis, simulation of different types of gunshot open globe injury, and visualization of changes by high-speed video fixation were carried out in the course of the work. Gunshot open globe injury type B: was reproduced on 9 cadaver rabbits (18 eyes), projectile used: modified dart, rifle cylinder pumping: 1 compression, average projectile velocity: 24 m/s. A lighting system consisting of 5 Gauss elementary 150 W LED lamps (Moscow, Russia), Iphone 7 (Apple, USA), Sony RX100 V (Sony, Japan), and Phantom Miro 310 (Vision Research, USA) were used for shooting. Results. The study has shown that only using the Phantom Miro 310 camera for filming such a fast-moving process as the formation of a gunshot open globe injury is reasonable and optimal. The trajectory of the projectile and the projectile itself can be clearly seen and the type of injury can be determined. Conclusions. A method of video fixation of a standardized model of gunshot open globe injury type B of the eye has been developed. This method is highly informative, easily reproducible and used for investigation of projectile ballistics, kinetics and macroscopic changes of the model of not only gunshot open globe injury type B, but also other types of eye trauma and also closed globe trauma. The study was performed at the Department of Ophthalmology of Prof. V.V. Volkov of the Military Medical Academy. Keywords: gunshot open globe injury, high-speed video fixation, model, technique.

In recent years, physicists, engineers and medical scientists have tried to demonstrate the biomechanics of gunshot wounds with numerical methods and experimental observations. Currently, the finite element method (FEM) is the most widely used numerical method among the studies related to ballistic wound injuries. However, when the FEM is used for the penetration analysis, the path of the projectile in the skull is subjected to extremely large deformations which will introduce errors due to distortion of elements. To overcome this error, the meshfree technique was established to simulate the gunshot wound as a preliminary study in which the skull was modeled by smoothed particle hydrodynamics (SPH) and the projectile was modeled by nondeformable rigid elements. In order to simulate a realistic penetration phenomenon, orthotropic material properties were defined for different regions (forehead, zygomatic and mandible) with material principal axis along the surface of the bones. Human response to the ballistics impacts were determined in terms of force occurring along the pathway of the bullet in the skull, residual velocity of the projectile and penetration depth. The obtained results were compared with the data reported in literature. As a result, mechanical behavior of the head under ballistic impacts simulated by the SPH, compared well with the results determined by the data given in literature, which indicates the applicability of the SPH method as a powerful technique in simulating different gunshot wound mechanisms.

Trauma training is a crucial element of medical education in the civilian sector, as well as in the military sector. Its aim is to prepare physicians, medics and nurses for stressful and demanding emergency situations. Training methods include live-tissue training (LTT) on animal models and simulation-based trauma education. For LTT, blast, gunshot or stab wounds are inflicted on anaesthetised animals, mostly goats and pigs, but sometimes non-human primates. This training method raises ethical concerns, especially in the light of increasingly sophisticated simulation-based methods. Despite these non-animal alternatives, LTT is still widely used due to its presumed educational benefits. In this paper, the question of whether LTT can still be justified, is discussed. We developed a normative framework based on the premise that LTT can only be ethically justified when it yields indispensable benefits, and when these benefits outweigh those of alternative training methods. A close examination of the evidence base for the presumed advantages of LTT showed that it is not superior to simulation-based methods in terms of educational benefit. Since credible alternatives that do not cause harm to animals are available, we conclude that LTT on animal models is ethically unjustified.

Frequent cases of man-made disasters, terrorist attacks and military conflicts lead to an increase in the number of victims. Significant soft tissue defects are known to result from gunshot wounds. So, as a result of mine-blasting injuries, defects in the skin and underlying tissues more than 10 cm in diameter are formed in 71.1% of cases. The prerequisite for the uncomplicated course of the wound process is to achieve an adequate comparison of the edges of the wound without excessive tension. To close such extensive wounds, various technical means are used: sutures on pads, various types of dermatotension. We have developed various models of wound contractors (RC) for treatment of wounds. With the help of the RC, a complete reposition and good adaptation of the edges of the wound is created. The wound closure method using these RC almost completely eliminates tissue cutting and limits the sawing effect to a minimum. This is explained by the effects of elastic forces reducing to zero when matching soft tissues and suturing. The use of hardware methods for suturing wounds requires the development of mathematical models of various types of wounds and surgical sutures. These models should provide a simulation of living tissues of the wound edges behavior to achieve the best results in the treatment of wounds by RC advanced technologies. The purpose of this study is to mathematically justify RC with the parallel holding of spokes. Another purpose is to develop a mathematical model of the wounds suturing by hardware technology.

BackgroundBystanders often hesitate when rendering first aid to females, particularly it requires disrobing the individual (Leary et al, 2018). In addition to the delayed application of first aid, the lifesaver’s actual task performance may also be less effective than when treating injured males. This can occur, for example, when the lifesaver does not fully expose the wound (Bell et al., 2020). The Army has invested heavily in the acquisition of realistic patient manikins for training combat medicine skills. However, given logistical constraints, it will be difficult to acquire an equal number of female patient manikins. Therefore, the purpose of this study was to develop and test a low-cost manikin “Gender Retrofit Kit” (GRK). The GRK included a breast “vest” that is affixed to the torso, a realistic vagina that is affixed to the groin, a wig, facial makeup, and instructions for “feminizing” the manikin’s appearance. MethodWe recruited a convenience sample of 36 Combat Lifesavers and Combat Medics who were completing their recurrent annual training. At the end of their scheduled training, the participants were invited to practice three medical procedures (treatment of penetrating trauma to the leg via tourniquet, treatment of gunshot wound via application of a chest seal, and treatment of tension pneumothorax via needle chest decompression). Of the three medical procedures, only the last two required disrobing the patient. Therefore, we hypothesized that if performance issues were to occur, they would be localized here. The participants practiced the three procedures using two different manikin types: a standard male manikin and the GRK-outfitted manikin. The order of manikin presentation was counterbalanced. Measures of task quality, task completion times, and usability questionnaires were collected. Results and ConclusionsThe sample was primarily male (78%), and included nearly equal numbers of Combat Lifesavers (42%) and Combat Medics (44%). A post-simulation questionnaire suggested no significant mean differences between the standard vs. GRK manikins with regard to the simulators’ perceived realism, anatomical correctness, or ability to provide meaningful skills practice. However, statistically higher mean scores were reported for questionnaire items that focused on the female manikin’s realistic breast tissue, realistic skin texture, and feminine facial appearance. Linear mixed models were used to separately test the effects of participant gender (or job title), manikin gender, and their interaction on both task performance speed and quality. There were no statistically significant differences in task completion order or speed of task completion. All participants performed the three tasks in accordance with the Army’s MARCH-E algorithm, and all had similar completion times. With regard to the quality of task performance, the analyses revealed only one statistically significant main effect of manikin gender: the GRK manikin had a lower mean task performance score for the treatment of gunshot wounds, which required disrobing the patient to apply the chest seal. Based on the results of this exploratory study, we are prioritizing potential improvements to the GRK, and are planning a more rigorously-controlled validation study with the revised prototype. Additional implications and lessons learned will be discussed.

Abstract Female soldiers are at greater risk of injury and have higher death rates compared to male soldiers. Female casualties are underrepresented in existing training materials for battlefield medics and the patient simulators are often masculine in appearance. The current study assesses the suitability of a female retrofit for male patient simulators and explores the existence of disparities in treatment between male and female patient simulators among combat medic trainees. Thirty-six participants undergoing training at a U.S. Army Medical Simulation Training Center performed a series of basic procedures on both a male patient simulator and a similar patient simulator with a female retrofit. The chest seal procedure was video-recorded and coded for errors committed by the trainees and analyzed to determine whether the apparent gender and order of the patient simulators affected error likelihood and rate. The results indicated that gender and order did not affect the likelihood of optimal performance, but if trainees treated the female retrofitted patient simulator first, they tended to commit more errors. Therefore, the use of a female retrofit may be useful for providing parity in training for gender; however, the issue of gender disparities remains a pressing issue for medical device design and research.
