Cesarean section is the most common surgery performed in obstetrics. Incorporating a simulation model into training provides a safe, low-stress environment in which students can gain skills and receive feedback. The purpose of this study was to determine the effectiveness of obstetrics simulator training for medical students doing their internship.
Twenty-five students posted in the Department of Obstetrics and Gynecology received a formal lecture on cesarean section and demonstration of the procedure on a mannequin in the first week of their internship, The study group (n = 12) practiced their skills on an obstetrics simulator under the direct supervision of a faculty member. The control group received no simulator-based training (n = 13) or further instruction. All students were asked to complete a prevalidated questionnaire to assess their level of confidence in performing the procedure after the educational session.
Compared with their peers in the study, students in the simulator group were significantly more likely to define the steps of cesarean section (91% vs 61.5%), and were comfortable in assisting cesarean section (100% vs 46.15%) as they were able to identify the layers of abdomen opened during cesarean section. All 12 students reported this as an excellent experience.
We were able to construct an inexpensive cesarean section trainer that facilitates instruction in cesarean section technique in a low-stress environment.
剖宫产是产科最常见的手术。将模拟模型纳入培训可提供一个安全、压力小的环境，让学生能够获得技能并得到反馈。本研究的目的是确定产科模拟器培训对正在实习的医学生的有效性。
在妇产科实习的25名学生在实习第一周接受了关于剖宫产的正式讲座以及在人体模型上进行的手术演示。研究组（n = 12）在教员的直接监督下在产科模拟器上练习技能。对照组未接受基于模拟器的培训（n = 13）或进一步指导。所有学生在教育课程结束后都被要求完成一份预先验证的问卷，以评估他们对进行该手术的信心水平。
与研究中的同龄人相比，模拟器组的学生更有可能明确剖宫产的步骤（91%对61.5%），并且在协助剖宫产时更得心应手（100%对46.15%），因为他们能够识别剖宫产时打开的腹部层次。所有12名学生都将此报告为一次极好的经历。
我们能够构建一种廉价的剖宫产训练器，在低压力环境中便于进行剖宫产技术的教学。
