ABSTRACT
Objective To explore the value of practicing PBL which was guided by MDT in teaching diagnoses and treatments of war wound and trauma caused by compound agents.Methods An emulational war wound case caused by compound factors was designed and a multi-disciplinary team been organized,then totally 45 interns who would graduate in 2017 were divide into two groups randomly,experimental group which had 23 cases received PBL model combined with MDT followed six step procedure which included case preparation by teachers,independent analysis and group discussion by interns,problem extraction by teachers and division of solution by interns before class,then answering and debating problems by interns in class,conclusion and reporting after class in the end,while the control group which had 22 cases received traditional teaching model in accordance with common case discussion in class including characteristics of patient,diagnosis and diagnostic basis,examinations needed to carry out,first aid measures and professional treatments.The effect of new teaching model was evaluated by assessment in class and questionnaire after class.The data was analyzed through Chi-square test by SPSS 22.0.Results Class assessment showed 18 (78.3％) interns in experimental group displayed good abilities of proposing,analyzing and resolving medical problem,as well as good presentation and speech skills.Questionnaire survey showed that not only clinical teaching of war wound and trauma could meet the demands of talent training in battle-field rescue,but also displayed new model,which could help interns to enhance abilities of first-aid and treatment of war wound on future war field,reinforce the consciousness of military medical support and service.In addition,it could clear confusion more professionally and strengthen teamwork and overall importance.Conclusion Applying PBL combined with MDT in teaching diagnoses and treatments of war wound and trauma can not only help interns to review and retain important knowledge of related subjects,but also improve the abilities of interns in clinical diagnoses and treatments,and moreover,it merges the medical knowledge and war wound cure together organically.In short,the new model is well worth applying in clinical teaching and military medical education because of its excellent effects.
ABSTRACT
Objective To investigate the radiographic body posture selection and improvement and it's application value.Methods We selected the uncommon postures optimal for radiographic diagnosis according to different body parts of compound injury patients,and offered the filming process and cautions of some improved postures in radiographic practice.Results Appropriate body posture,improved filming position and processes,optimized parameters of exposure,and the application of digital imaging devices could ensure the image quality of diagnosis.Conclusion Effective filming processes,improved body postures and variable digital devices should be selected in compound injury patients according to practical condition.
