Study Objective

To determine the utility of a 3D vulvar model for teaching pediatric straddle injury repair.

Design

Prospective study.

Setting

Two academic hospitals.

Participants

Twenty obstetrics and gynecology residents

Interventions and Main Outcome Measures

Knowledge score on the basis of a 7-question pre/post test. Likert scale questions evaluated the 3D model as a teaching tool.

Results

Twenty residents participated; 2 (10%) had ever repaired a straddle injury. Knowledge scores increased after model use and didactic session from 3.05 of possible 7 to 6.35; P = .001. Only 2/20 (10%) residents “agreed” or “strongly agreed” with the statement, “I am comfortable repairing a straddle injury” before the intervention, compared with 19/20 (95%) afterward (P < .001). Of 20 residents, 19 (95%) believed that it simulated surgical experience “very well” or “well.”

Conclusion

The use of a 3D pediatric vulvar model can simulate surgical experience and can be an effective teaching tool when combined with a didactic session on pediatric straddle injury.

使用 3D 打印模型教授小儿跨骑损伤修复

学习目标

确定 3D 外阴模型在小儿跨骑损伤修复教学中的应用。

设计

前瞻性研究。

环境

两家学术医院。

参与者

妇产科住院医师20人

干预措施和主要结果措施

知识分数基于 7 个问题的前/后测试。李克特量表问题将 3D 模型作为教学工具进行评估。

结果

二十位居民参加；2 (10%) 曾经修复过跨骑伤。模型使用和教学会议后知识得分从可能的 7 的 3.05 增加到 6.35；P  = .001。只有 2/20 (10%) 的居民在干预前“同意”或“强烈同意”“我很乐意修复跨骑伤”这一说法，而干预后则为 19/20 (95%) ( P < .001) . 在 20 名住院医师中，19 名 (95%) 认为它模拟的手术体验“非常好”或“很好”。

结论

使用 3D 小儿外阴模型可以模拟手术经验，并且与小儿跨骑损伤的教学课程相结合，可以成为一种有效的教学工具。
