Effective first aid on the battlefield is vital to minimize deaths caused by war trauma and improve combat effectiveness. However, it is difficult for junior medical students, which have relatively poor human anatomy knowledge and first aid experience. Therefore, we aim to create a treatment simulation software for war trauma, and to explore its application for first aid training. METHODS : This study is a quantitative post-positivist study using a survey for data collection. First, high-resolution, thin-sectional anatomical images (Chinese Visible Human (CVH) dataset) were used to reconstruct three-dimensional (3D) wound models. Then, the simulation system and the corresponding interactive 3D-PDF, including 3D models, graphic explanation, and teaching videos, were built, and used for first aid training in army medical college. Finally, the interface, war trauma modules, and training effects were evaluated using a five-point Likert scale questionnaire. All measurements are represented as mean and standard deviations. Moreover, free text comments from questionnaires were collected and aggregated.
The simulation software and interactive 3D-PDF were established. This included pressure hemostasis of the vertex, face, head-shoulder, shoulder-arm, upper forearm, lower limb, foot, and punctures of the cricothyroid membrane, pneumothorax, and marrow cavity. Seventy-eight medical students participated in the training and completed the questionnaire, including 66 junior college students and 12 graduate students. The results indicated that they were highly satisfied with the software (score: 4.64 ± 0.56). The systems were user-friendly (score: 4.40 ± 0.61) and easy to operate (score: 4.49 ± 0.68). The 3D models, knowledge of hemostasis, and puncture were accurate (scores: 4.41 ± 0.67, and 4.53 ± 0.69) and easily adopted (scores: 4.54 ± 0.635, and 4.40 ± 0.648). They provided information about hemostasis and puncture (all scores > 4.40), except for cricothyroid membrane puncture (scores: 4.39 ± 0.61), improved the learning enthusiasm of medical students (score: 4.55 ± 0.549), and increased learning interest (score: 4.54 ± 0.57).
Our software can effectively help medical students master first aid skills including hemostasis, cricothyroid membrane and bone marrow puncture, and its anatomy. This may also be used for soldiers and national first aid training.
有效的战场急救对于将战争创伤造成的死亡人数降到最低并提高战斗力至关重要。然而，对于解剖学知识和急救经验相对较差的低年级医学生来说，这是很困难的。因此，我们旨在创建一个用于战争创伤治疗的模拟软件，并探索其在急救培训中的应用。
这是一项使用问卷调查进行数据收集的定量后实证研究。首先，使用高分辨率、薄切片解剖图像（中国可视人数据集）重建三维（3D）伤口模型。然后，构建模拟系统和相应的交互式 3D-PDF，包括 3D 模型、图形说明和教学视频，用于军医大学的急救培训。最后，使用五点李克特量表问卷评估界面、战争创伤模块和培训效果。所有测量结果均表示为均值和标准差。此外，还收集了问卷的自由文本评论并进行了汇总。
建立了模拟软件和交互式 3D-PDF，其中包括顶点、面部、头部肩部、肩部臂部、前臂上部、下肢、足部以及甲状软骨膜、气胸和骨髓腔的压迫止血穿刺。78 名医学生参加了培训并完成了问卷调查，其中包括 66 名大专生和 12 名研究生。结果表明，他们对该软件非常满意（评分：4.64±0.56）。系统用户友好（评分：4.40±0.61）且易于操作（评分：4.49±0.68）。3D 模型、止血知识和穿刺术准确（评分：4.41±0.67 和 4.53±0.69）且易于采用（评分：4.54±0.635 和 4.40±0.648）。它们提供了有关止血和穿刺的信息（所有评分均大于 4.40），除了甲状软骨膜穿刺术（评分：4.39±0.61）外，还提高了医学生的学习积极性（评分：4.55±0.549）和学习兴趣（评分：4.54±0.57）。
我们的软件可以有效地帮助医学生掌握包括止血、甲状软骨膜和骨髓穿刺在内的急救技能及其解剖学知识。它也可用于士兵和国家急救培训。
