[PMID: 36008213 PMCID: PMC9912295 DOI: 10.1016/j.cjtee.2022.07.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 05/31/2022] [Accepted: 06/30/2022] [Indexed: 02/04/2023] Open
Abstract
PURPOSE To develop animal models of penetrating thoracic injuries and to observe the effects of the animal model-based training on improving the trainees' performance for emergent and urgent thoracic surgeries. METHODS With a homemade machine, animal models of lung injuries and penetrating heart injuries were produced in porcine and used for training of chest tube drainage, urgent sternotomy, and emergent thoracotomy. Coefficient of variation of abbreviated injury scale and blood loss was calculated to judge the reproducibility of animal models. Five operation teams from basic-level hospitals (group A) and five operation teams from level III hospitals (group B) were included to be trained and tested. Testing standards for the operations were established after thorough literature review, and expert questionnaires were employed to evaluate the scientificity and feasibility of the testing standards. Tests were carried out after the training. Pre- and post-training performances were compared. Post-training survey using 7-point Likert scale was taken to evaluate the feelings of the trainees to these training approaches. RESULTS Animal models of the three kinds of penetrating chest injuries were successfully established and the coefficient of variation of abbreviated injury scale and blood loss were all less than 25%. After literature review, testing standards were established, and expert questionnaire results showed that the scientific score was 7.30 ± 1.49, and the feasibility score was 7.50 ± 0.89. Post-training performance was significantly higher in both group A and group B than pre-training performance. Post-training survey showed that all the trainees felt confident in applying the operations and were generally agreed that the training procedure were very helpful in improving operation skills for thoracic penetrating injury. CONCLUSIONS Animal model-based simulation training established in the current study could improve the trainees' performance for emergent and urgent thoracic surgeries, especially of the surgical teams from basic-level hospitals.

Development of a post-mortem human specimen flow model for advanced bleeding control training. Injury 2023; 54:214-222. [PMID: 35948510 DOI: 10.1016/j.injury.2022.07.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Revised: 07/26/2022] [Accepted: 07/29/2022] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Prompt and effective hemorrhage control is paramount to improve survival in patients with catastrophic bleeding. In the ever-expanding field of bleeding control techniques, there is a need for a realistic training model to practice these life-saving skills. This study aimed to create a realistic perfused post-mortem human specimen (PMHS) flow model that is suitable for training various bleeding control techniques. MATERIALS AND METHODS This laboratory study was conducted in the SkillsLab & Simulation Center of Erasmus MC, University Medical Center Rotterdam, the Netherlands. One fresh frozen and five AnubiFiX® embalmed PMHS were used for the development of the model. Subsequent improvements in the exact preparation and design of the flow model were made based on model performance and challenges that occurred during this study and are described. RESULTS Circulating arteriovenous flow with hypertonic saline was established throughout the entire body via inflow and outflow cannulas in the carotid artery and jugular vein of embalmed PMHS. We observed full circulation and major hemorrhage could be mimicked. Effective bleeding control was achieved by placing a resuscitative endovascular balloon occlusion of the aorta (REBOA) catheter in the model. Regional perfusion significantly reduced the development of tissue edema. CONCLUSION Our perfused PMHS model with circulating arterial and venous flow appears to be a feasible method for the training of multiple bleeding control techniques. Regional arteriovenous flow successfully reduces tissue edema and increases the durability of the model. Further research should focus on reducing edema and enhancing the durability of the model.

Abstract
INTRODUCTION Training combat personnel in combat first-aid skills has faced many challenges over time, such as the need to combine tactics with medicine and to overcome combat personnel's lack of medical background knowledge. Therefore, many simulation methods are currently being developed, each of which has its advantages and disadvantages. In this study, a combined simulation method involving live-actor patients using a wearable training apparatus was developed, and the effects of this method were observed. MATERIALS AND METHODS Focusing on the major causes of preventable deaths among victims killed in action, wearable training apparatuses simulating massive hemorrhage, airway obstruction, and tension pneumothorax were designed and produced. Methods of simulating these three injury types using live-actor patients with these training apparatuses were developed, and medical teachers evaluated the simulation effects. The live-actor patients were incorporated into a tactical scenario to train and test nonmedical and medical students in year 3, respectively. High-fidelity simulator-based training and traditional training without simulation served as the control. A post-training survey using a 7-point Likert scale evaluated the trainees' feelings toward these training approaches. RESULTS Three types of training apparatuses were developed to simulate three life-threatening injuries, and the simulation effects of the live-actor patients using these apparatuses were highly recognized by medical teachers. Both live-actor patients and high-fidelity simulator-based training improved performance significantly more than traditional training. However, the improvement due to training with live-actor patients was greater than that due to high-fidelity simulator-based training for nonmedical students, whereas there was no difference between these two simulation methods for medical students. A post-training survey revealed that all the trainees were confident in practicing first-aid skills after training, and they all agreed that live-actor patients could combine tactical situations with first aid better than high-fidelity simulators. The nonmedical students strongly agreed that live-actor patients were more helpful in the training of injury evaluation than high-fidelity simulators. CONCLUSIONS The method using wearable training apparatus-based live-actor patients was satisfying and effective for teaching life-saving combat first-aid skills, especially for nonmedical students.

Abstract
INTRODUCTION The Stop the Bleed (STB) program trains the general public on identifying and treating life-threatening bleeding. Data on efficacy and retention of skills taught through this program are limited, with the role of high-technology modalities to augment the program, such as simulation and feedback devices, untested. METHODS A convenience sample of 66 school personnel participated in an open-label observational study from January to August 2019. The control group received the standard bleeding control course, while the intervention group received the bleeding control course with addition of a simulation and a feedback device for wound packing. Assessment was performed by STB instructors using performance metrics from prior studies as well as a feedback device. Retention testing was performed 2 to 8 months after intervention. The study was approved by the hospital's institutional review board. RESULTS The intervention group performed better than the control group on correct tourniquet application [90.3% vs. 71.0%; odds ratio (OR) = 11.28; P = 0.015; 95% confidence interval (CI) = 1.86 to 104.67] wound packing scores (59.5% vs. 29.6%; OR = 0.33; P = 0.007; 95% CI = 9.36 to 56.00) and were more likely to assess their safety (OR = 5.49; P = 0.034; 95% CI = 1.28 to 27.66), and reported higher comfort scores on stepping into an emergency scenario (OR = 11.19; P = 0.004; 95% CI = 2.51 to 63.11), wound packing (OR = 5.16; P = 0.025; 95% CI = 1.35 to 22.46), and using a tourniquet (OR = 11.41; P = 0.003; 95% CI = 2.57 to 67.59). Thirty-one participants (46.9%) were assessed again at retention 2 to 8 months later where scores for tourniquet placement and wound packing were not significantly different in the two groups. CONCLUSIONS Augmenting STB with simulation and feedback improved both self-reported comfort level and skill set of participants, but the retention of skills was poor in both groups.
