RESUMO
Based on the latest results of international researches, combining with the experiences of our team in the simulation of acute dyspnea, Xiangya Hospital Central South University has summarized 7 characteristics, procedures and methods of debriefing, including that immediate feedback happens after simulation; feedback is provided by a trained instructor with clinical experience; feedback time is at least longer than the simulation time; various international methods of feedback can be used; the content of feedback is the learning objective; oral feedback is preferred; video can be used to review the details. The study aims to provide a theoretical basis for debriefing in domestic scenario stimulation teaching, and finally improve the effectiveness of the scenario stimulation teaching.
RESUMO
Objective:To evaluate the use of ulthera in carotid body tumor resectionMethods:From Jun 2004 to Jun 2019 at the First Hospital of China Medical University. Forty-three shamblin grade Ⅱ or Ⅲ patients were retrospectively assigned to ulthera assisted carotid body tumor resection (26 cases) and traditional carotid body tumor resection (17 cases).Results:In ulthera assisted group, the average tumor diameter was (4.0±0.6) cm, compared to (3.9±0.9) cm in traditional carotid body tumor surgery group, P=0.875. The operation time of the two group was respectively (117.6±39.8) min and (149.4±55.0) min ( P=0.005), blood loss (145.7±70.6) ml vs. (194.1±80.7) ml ( P=0.006), hospital stay was (16.8±7.5) d vs. (22.7±13.0) d ( P=0.017), and following-up period was between 6 and 180 months. One patient relapsed in ulthera assisted group. The postoperative complications occurred in 8 and 7 cases respectively. Conclusion:Ulthera assisted carotid body tumor resection helps shorten operation time, hospital stay and decrease intraoperative blood loss.
RESUMO
Objective:To explore the influence of virtual simulation experiment project on the experimental teaching effect of infectious diseases.Methods:Ten experimental contents were selected, including 3 703 students majoring in clinical five-year program, eight-year program, anesthesia, psychiatry and other majors of Medicine School of Central South University. The teaching effect and students' satisfaction were evaluated through examination and personal questionnaire survey. The measurement data was expressed by (mean ± standard deviation), the counting data was illustrated by percentage. The rate is compared by Chi-square test, and the difference is statistically significant when P<0.05. Results:All the students took part in the examination of 10 items. Except for item 8, the scores of students in all items had a large variance, with almost same number of high score students and low score students. Learning attitude is closely related to learning effect. Among the students who think it's necessary to learn, 20.5% and 53% have excellent learning effect and good learning effect, respectively. Compared with offline experiment teaching, virtual simulation teaching has both advantages and disadvantages, and needs to further improve the satisfaction of students.Conclusion:Virtual simulation teaching of infectious diseases is unable to completely replace offline teaching, and the combination of virtual and reality is more conducive to improving the quality of medical students.
