RESUMO
Objective:To explore the application effect of case-based learning (CBL) combined with three-dimensional (3D) imaging technology in thoracic surgery probationary teaching.Methods:Ninety thoracic surgery interns in the Affiliated Hospital of Yangzhou University, China in 2019 were selected and divided into the conventional theoretical teaching group (group A), CBL group (group B), and CBL combined with 3D imaging technology group (group C) according to the random number table method. Group A was taught with conventional theory; group B was taught by CBL; in group C, 3D imaging software was used to reconstruct computed tomography data based on CBL. The theoretical scores of the three groups were evaluated respectively, and a questionnaire survey was conducted on the students (including whether the teaching is conducive to stimulating the interest and enthusiasm of learning, whether it is conducive to the establishment of clinical thinking, evaluation of advantages and disadvantages of the teaching method, and whether the teaching method is conducive to the mastery of theoretical knowledge). SPSS 20.0 was used for analysis of variance, t test, and Chi-square test. Results:The theoretical score of group A (85.83±4.62) was the lowest, and the theoretical score of group B was significantly lower than that of group C (89.71±5.84 vs. 94.60±6.28); the answer time of group C (286.68±77.56 seconds) was the shortest, and the answer time of group B was significantly shorter than that of group A (359.78±80.55 vs. 423.31±83.53 seconds, P<0.001). Group C was significantly better than group B and group A in the aspects of stimulating interest and enthusiasm in teaching, conducive to the establishment of clinical thinking, advantages of the teaching method, and conducive to the mastery of theoretical knowledge, and group B was significantly better than group A ( P<0.001). Conclusion:The combination of CBL and 3D reconstruction technology improves the recognition of thoracic surgery interns to the teaching method, increases their theoretical scores, stimulates their learning interest and enthusiasm, cultivates their clinical thinking, and enhances their mastery of theoretical knowledge.
RESUMO
BACKGROUND@#Lung cancer is currently the leading malignant tumor in both domestic and foreign morbidity and mortality. Surgical treatment is the main treatment option for lung cancer. The aim of this study is to explore the effects of enhanced recovery after surgery (ERAS) combined with respiratory function exercise combined with single-hole thoracoscopic surgery on lung cancer patients with postoperative pulmonary complications, postoperative pain, time to get out of bed, time to extubation and length of hospital stay.@*METHODS@#A total of 240 patients who underwent endoscopic lung cancer surgery at the Affiliated Hospital of Yangzhou University and the Yancheng First People's Hospital from October 2017 to October 2019 were randomly divided into 4 groups, with 60 patients in each group. Patients in group A underwent single-hole thoracoscopic surgery, and preoperatively performed ERAS concept education and respiratory function training; group B used conventional 3-hole thoracoscopic surgery, and performed ERAS concept education and respiratory function training before operation; group C used conventional 3-hole thoracoscopic operation surgery, routine hospitalization education and nursing guidance, routine respiratory function training, no preoperative ERAS concept education; group D used single-hole thoracoscopic surgery, routine hospitalization education and nursing guidance, routine respiratory function training, no preoperative ERAS concept mission. The number of postoperative pulmonary complications, postoperative pain, time to get out of bed, extubation time, and hospital stay were recorded in the four groups.@*RESULTS@#Compared with the groups B, C, and D, the incidence of pulmonary complications was significantly reduced, and the time to get out of bed, extubation time, and hospital stay were significantly shortened in group A. Compared with groups B, C, the postoperative pain was significantly reduced in group A. Compared with group C, the pulmonary complications were significantly reduced, and the time to get out of bed, extubation time and hospital stay were significantly shortened in group B. The differences were statistically significant (P0.05).@*CONCLUSIONS@#For patients with single-hole thoracoscopic lung cancer surgery, the ERAS concept guidance can effectively reduce the incidence of pulmonary complications and postoperative pain, shorten the time to get out of bed, the time to extubate, and the length of hospital stay.
