RESUMO
Objective:To explore the teaching effect of 3D simulated wound model combined with problem -based learning (PBL) teaching in the standardized residency training of plastic surgery department. Methods:Totally 90 residents trained in the plastic surgery department of Changhai Hospital of Naval Medical University from June 2016 to September 2019 as the research objects were divided into control group and experimental group in average. The control group received traditional teaching and the experimental group accepted the 3D simulated wound model combined with PBL teaching. Then the out -department examination results and questionnaires evaluation were compared between the two groups. SPSS 19.0 was used to conduct t test on the experimental data. Results:The theoretical and practical scores of residents in the experimental group [(49.23±7.25) points and (36.38±5.29)] points were significantly better than those in the control group [(44.43±5.57) points and (28.94±6.97)] points ( P<0.05). In the questionnaire, the scores of active learning initiative, practical operation ability and clinical strain capacity of residents in the experimental group were all higher than those in the control group ( P<0.05), and there was no statistically significant difference in teamwork ability between the two groups ( P>0.05). Conclusion:The 3D simulated wound model combined with PBL teaching can be used in the teaching of standardized residency training of plastic surgery. Compared with traditional teaching, this teaching method has significant advantages and is worthy of promotion.
