ABSTRACT

Objective:

To meet the individualized needs of residents in standardized residency training of cardiac intervention specialty for cardiac ultrasound teaching, to construct a bionic 3D printing model of ultrasound source, and to discuss its application value in ultrasound teaching and simulation exercises.

Methods:

Sixty residents majored in cardiovascular medicine receiving standardized residency training of ultrasound in ultrasound imaging department of Renmin Hospital of Wuhan University were randomized into experimental group and control group in average. The experimental group adopted ultrasound bionic 3D printing heart model combined with problem-based learning (PBL) teaching method, and the control group adopted traditional multimedia PPT combined with PBL teaching method. At the end of teaching activities, theoretical examination, operation assessment and questionnaire survey were conducted to evaluate and compare the teaching effect between the two groups. SPSS 21.0 software was performed for t test.

Results:

The theoretical examination scores of the experimental group and the control group were (81.4±8.2) points and (74.8±9.4) points, respectively, P=0.002, and the operation assessment scores were (89.1±5.6) points and (71.5±8.8) points, respectively, P<0.001. The questionnaire survey showed that the experimental group had better feedbacks than the control group in the aspects of mastery of heart anatomy knowledge, learning experience, learning interest, learning efficiency, understanding of interventional heart disease, clinical skills of interventional operation and overall satisfaction (all P<0.05).

Conclusions:

Ultrasound bionic 3D printing combined with PBL teaching method can help strengthen the mastery of cardiac anatomy knowledge, promote the learning experience of cardiac ultrasound and improve the skills of interventional operation. The teaching effect is significant and the students' satisfaction is high.
