Objective　To investigate the effect of situational simulation combined with video feedback in cardiopulmonary and abdominal clinical probation of diagnostics. Methods Two hundred and twenty-four clinical undergraduates from the second affiliated hospital of Guangxi Medical University were randomized into the experimental group (n=112) and the control group (n=112). The experimental group applied situational simulation combined with video feedback methods in the cardiopulmonary and abdominal clinical probation. In other words

according to the assignment of diseases

two students played the role of physician and patient and conducted corresponding consultation and physical examination

in which the positive and negative video feedback were integrated to standardize students' physical examination skills. The control group adopted conventional teaching method. The teaching effect of the two groups was evaluated through unified and standardized scores of theoretical tests

cases analysis

and clinical skills operation

and the experimental group was conducted anonymous questionnaires to 112 students. SPSS 22.0 was used to perform the t test. Results　The evaluation results show that the average scores of theoretical tests (90.12±0.94)

cases analysis (9.30±0.10) and physical examination (93.50±0.72) in the experimental group are higher than those of the control group

(83.20±1.66)

(8.10±0.11)

(85.00±1.75)

respectively

with statistical significance (P<0.05). All 112 questionnaires were collected

with an effective rate of 100%. The percentage of yes respondents is as follows

91.1% of Enhancing the mastery and application of knowledge; 97.3% of Cultivating clinical thinking; 87.5% of Improving doctor-patient communication skills; however

there are 93.8% students believe that this new teaching approach takes more time to prepare before class

consequently

their initiative and enthusiasm of study and learning interest have slid into decline

with percentage of 80.4% and 83.0%

respectively. Conclusion　The teaching method of situational simulation and video feedback in cardiopulmonary and abdominal clinical probation of diagnostics is beneficial to enhance students' understanding and mastery of theoretical knowledge

standardize physical examinations

cultivate clinical thinking ability and improve the doctor-patient communication skills. However

it takes a lot of time for students to prepare before class. If they fail to make reasonable arrangements

the teaching effect will be half the effort and students' initiative and enthusiasm of learning will be reduced.
