目的 研究气管插管训练模型的构造与性能对教学效果的影响。方法 将不同构造的三款气管插管训练模型命名为M1、M2和 M3，并且选择第五年医学生91名，首先统一进行30分钟的气管插管理论学习并考试，之后随机分A、B、C三组，分别在M1、M2和M3模型上训练90分钟，并在各自训练模型上进行操作考核(即训练与考核同款模型)，记录成绩。之后更换模型，在其他两款模型上进行第2、3次考核，比较三次成绩。1月后再次进行理论与操作考核。同时学生与教员分别填写对模型的评价量表。结果 1. 三组学生人数(31

32)及性别构成(男/女10/21

9/19

12/20)无统计学差异；训练前理论考试分别为85.46

78.35

79.48无统计学差异。2. 操作考核：第1次考核成绩：在M1模型上训练的A组成绩明显低于其他两组，78.93

84.76

85.32，有统计学意义；更换模型后第2、3次考核，A组成绩明显高于其他两组，有统计学意义。3. 1月后再次进行操作考核，A组成绩85.46和85.22明显高于B组78.35和70.13、C组79.48和69.76，有统计学意义。4. 学生及教员对三组模型评价结果：M1组得分4(4

M2 and M3

and 91 medical students of grade 5 were selected. After 30 minutes theoretical knowledge learning and examination of intubation

they were randomly divided into Group A

B and C

and trained respectively on the M1

M2 and M3 for 90 minutes

then accepted first evaluation. The mannequins were exchanged within the three groups and students were repeated training and evaluation

later results of three groups were compared. After one month

group A

B and C received the examination and evaluation again. Students and instructors all filled out the evaluation scale for M1、M2 and M3. Results 1)The quantity of three groups (31

28

32) and gender (male/female

10/21

9/19

12/20) showed no statistical difference

and the pre-training test was 85.46

78.35

79.48

showed no statistical difference.2)After training

the group A scored significantly lower on the M1 than group B

78.93

84.76

85.32

statistically significant. In the second and third examination after exchanging mannequin，the results of group A were significantly higher than the other two groups.3)After one month

the score of group A were significantly higher than group B or C.4)The evaluation of students and instructors for mannequins: M1 score 4(4

5)

5(4.63

5) was significantly higher than that in group B 3(3

showed statistically significant differences. Conclusion The constructs of the endotracheal intubation training mannequins of tracheal intubation indeed influenced the teaching effect.
