摘要
目的 探究基于虚拟仿真系统的口腔局部神经阻滞麻醉实验教学方法对于传统教学方法的提升作用.方法 将118名口腔医学本科生随机分为两组,试验组采用基于虚拟仿真系统的教学,对照组采用传统教学.通过课程反馈问卷、理论测试成绩分析、实施麻醉和接受麻醉的学员对本次麻醉的评价,以及教师对麻醉成功与否的评价来综合评估教学结果,采用SPSS 23.0进行t检验和卡方检验.结果 两组学员基线水平无明显差异.试验组学员认为学习的生动性更高(t=4.24,P= 0.005),对局麻的自信心也更强(t=4.99,P<0.001).试验组自我感觉注射过程中针尖抖动更少(t= 2.22,P=0.048),与下颌骨内侧骨面接触更好(t=2.22,P=0.020).接受麻醉的学员反映试验组注射时针尖刺痛感较轻(t=1.99,P=0.029),下牙槽神经麻醉的效果较好(t=3.36,P=0.039).教师评估发现试验组的下牙槽神经阻滞失败率明显低于试验组(χ2=4.40,P=0.036).结论 虚拟仿真系统可优化口腔局部神经阻滞麻醉实验教学并能取得良好的教学效果.
Abstract
Objective To investigate the effect of the virtual simulation system-based teaching method for the experimental course of oral local nerve block anesthesia in improving the effect of traditional teaching methods.Methods One hundred and eighteen undergraduate dental students were randomly divided into two groups,the experimental group was taught using a virtual simulation-based system,and the control group was taught using traditional teaching.The results of the teaching were comprehensively evaluated through course feedback questionnaires,analysis of theoretical test scores,evaluations of the trainees administering and receiving anesthesia on the current anesthesia,and faculty evaluations of the success of the anesthesia,and t-tests and chi-square tests were performed using SPSS 23.0.Results There was no significant difference in baseline level between the two groups.The students in the experimental group thought that the learning was more vivid(t=4.24,P=0.005)and had more self-confidence in local anesthesia(t=4.99,P<0.001).The students in the experimental group felt less needle tip jitter during injection(t=2.22,P=0.048)and better contact with the medial surface of the mandible(t=2.22,P=0.020).The students who received anesthesia reported less pain during injection(t=1.99,P=0.029)and better anesthesia of the inferior alveolar nerve(t=3.36,P=0.039)in the experimental group.Teacher assessment revealed that the experimental group had a significantly lower failure rate of inferior alveolar nerve block than the control group(χ2=4.40,P=0.036).Conclusions The virtual simulation system can optimize the experimental teaching of oral local nerve block anesthesia and can achieve a satisfactory teaching effect.
