摘　　要：目的评价虚拟仿真系统应用于口腔局部麻醉教学的效果。方法于2019年7月选择兰州大学口腔医学院2017级口腔医学专业五年制本科生60人为研究对象,采用随机数字表法将学生分为对照组(C组)、仿头模组(F组)和虚拟仿真组(V组),每组20人。全部学生统一接受理论知识培训及观看操作演示,结束后进行理论考试。将C组学生两两分组互相进行下牙槽神经阻滞麻醉,由专业教师进行评分;F组和V组分别在仿头模和虚拟仿真系统上进行练习,结束后进行麻醉操作考核。操作考核后三组统一进行第二次理论考试,额外再对F组和V组进行问卷调查。采用SPSS 22.0软件对数据进行统计学处理,各分组前后两次理论成绩的比较采用配对样本t检验,三组操作成绩和麻醉效果评分的比较采用单因素方差分析,组间操作成绩和麻醉效果评分的比较则采用独立样本t检验。结果麻醉理论知识考核结果显示,V组学生经过练习后,第二次理论成绩明显提高,与第一次理论成绩相比差异具有统计学意义(t=3.768,P=0.001),而F组和C组学生的第二次理论成绩与第一次理论成绩相比,差异无统计学意义(t_F=2.079,P_F=0.051;t_C=0.538,P_C=0.597)。在操作考核中,三组的考核成绩分别为C组(82.1±2.6)分、F组(83.9±1.5)分、V组(85.7±2.5)分,差异具有统计学意义(F=12.629,P<0.001)。麻醉效果考核成绩分别为C组(63.5±6.7)分、F组(68.5±5.9)分、V组(74.0±6.8)分,差异具有统计学意义(F=13.157,P<0.001)。调查问卷结果显示,大多数学生认为虚拟仿真系统更能够提高操作技能、理论知识水平及学习兴趣。结论在口腔外科麻醉的临床前教学过程中,虚拟仿真系统更有利于提高口腔医学生的操作技能和理论知识的掌握,值得推广。Objective To evaluate the effect of applying virtual simulation system to local anesthesia teaching in oral surgery.Methods Sixty undergraduates from grade 2017 five-year program of school of stomatology,Lanzhou University were selected as research subjects in July 2019.The students were divided into three groups by using the random number table,named control group(group C),head-simulator group(group F)and virtual simulation system group(group V),with 20 students in each group.Three groups received theoretical knowledge training and watched the operation demonstration.After the training and demonstration,they took the theoretical examination.Then group C students were divided into ten groups in pairs for inferior alveolar nerve block anesthesia,with professional teachers scoring the scores.The students in group F were trained on the head simulator and the students in group V were trained on the virtual simulation system.After the training,the inferior alveolar nerve block anesthesia injection operation examination and the second theoretical examination for three groups were conducted.Questionnaire surveys were conducted for group F and group V.SPSS 22.0 statistical software was used for statistical analysis of the data.The comparison of two theoretical scores of each group was analyzed by paired sample t-test.The comparisons of the operation scores and anesthesia effect scores of different groups were analyzed by one-way ANOVA.The comparisons of the operation scores and anesthesia effect scores between two groups were analyzed by independent-sample t test.Results After the practice,the theoretical scores of the students in group V had been improved greatly(tV=3.768,PV=0.001).However,the difference between the second theoretical scores and the first theoretical scores of students in group F and group C was not statistically significant(tF=2.079,PF=0.051;tC=0.538,PC=0.597).The operation assessment scores were 82.1±2.6 for group C,83.9±1.5 for group F and 85.7±2.5 for group V,and the difference was statistically
