目的 探索全沉浸式虚拟现实(virtual reality,VR)技术在剖宫产手术教学中的应用效果。方法 2021年9月2日至17日,选取南方医科大学临床医学专业13名本科生(6名临床医学六年制专业六年级学生、5名临床医学五年制专业三年级学生、2名临床医学八年制专业六年级学生)和南方医科大学南方医院4名低年资住院医师为研究对象(下文统一简称为学员)。采用VR软件对学员进行剖宫产手术教学,并采用其内置评分系统评估学员完成剖宫产手术操作考核成绩和完成时间;采用问卷调查学员对教学的满意度。采用t检验比较手术考核成绩、手术完成时间及教学前后对自身能力评价的差异。结果 教学前后学员完成剖宫产手术操作考核成绩分别为(52.94±19.06)分和(85.47±3.39)分,手术完成时间分别为(21.66±8.85)分钟和(12.37±1.58)分钟,其差异均具有统计学意义(均P＜0.05)。问卷调查结果显示,17名学员中,16名学员认为全沉浸式VR技术有利于掌握外科手术技能要点、增强临床自信,希望将全沉浸式VR技术纳入技能常规教学中。结论 全沉浸式VR技术用于剖宫产手术教学,有助于提高学员对剖宫产手术流程的掌握、缩短操作时间,并得到了学员的普遍认可。

Objective To explore the effect of fully immersive virtual reality (VR) technology in the teaching of cesarean section (CS) surgery. Methods From September 2 to 17, 2021, 13 undergraduate students of clinical medicine major of Southern Medical University and 4 junior residents of Nanfang Hospital of Southern Medical University were enrolled (hereinafter referred to as trainees). In the teaching of CS surgery, VR software was used to train the trainees, and the built-in scoring system of the VR software was used to assess the accuracy and completion time of the trainees in completing the CS surgical operation, and a questionnaire was used to investigate the trainees' satisfaction with the training. The t-test was used to compare the differences between the two groups. Results The scores of trainees completing CS surgical operation before and after the training were (52.94±19.06) and (85.47±3.39), and the operation time was (21.66±8.85) and (12.37±1.58) minutes, respectively, and the differences were statistically significant (all P<0.05). The results of the questionnaire survey showed that 16 out of 17 trainees believed that VR technology was beneficial for mastering the key points of surgical skills, enhancing clinical confidence, and hoped to incorporate VR technology into the routine skills training. Conclusions Fully immersive VR based for teaching CS surgery helps to improve trainees' mastery of the CS procedure, shorten operation time, and is generally recognized by trainees.
