ObjectiveTo examine the differences between totally thoracoscopic surgery and median sternotomy in scope of trauma, postoperative recovery and postoperative complications. MethodsWe retrospectively analyzed the clinical data of 331 patients with cardiac myxoma in our hospital between January 2001 and November 2015. The patients were devided into 2 groups by the different methods of operation:a totally thoracoscopic surgery group including 196 patients with 71 males and 125 females at a mean age of 50 (42.00-57.50) years, and a median sternotomy group including 135 patients, with 53 males and 82 females at a mean age of 52 (38.00-61.00) years. The clinical records of the two groups were compared in scope of trauma, postoperative recovery, and postoperative complications. ResultsThere was shorter time in breathing machine and ICU time (P<0.001), and fewer volume in blood transfusion, blood loss (P<0.001) in the totally thoracoscopic surgery group. There was less pain and postoperative complications (P<0.001) in the totally thoracoscopic surgery group. The aortic clamp time in the totally thoracoscopic surgery group was not significantly different compared with that in the median sternotomy group (P=0.15) While cardiopulmonary bypass time was shorter in the median sternotomy group (P<0.001). ConclusionTotally thoracoscopic surgery is a safe and reliable method in treating cardiac myxoma. Our results suggest that totally thoracoscopic surgery has the advantage of fewer blood loss, blood transfusion, and postoperative complications compared with median sternotomy surgery. Totally thoracoscopic surgery leads to earlier recovery and less pain.
ObjectiveTo explore the teaching effects of scene simulation of medical disputes in clinical skills training. MethodsBetween September 2012 and June 2013, 93 clinical medicine undergraduates in Grade 2010 (8-year study) were randomly divided into the scene simulation teaching of medical disputes group (n=47) and the control group with traditional training (n=46) for clinical skills training. Teaching effects were assessed by clinical skills operation tests. ResultsThrough scene simulation teaching of medical disputes, the trainees' clinical disposal ability, operating skills, communication skills, cultural knowledge, and legal knowledge dimension scores were all significantly better than previous tests (P<0.05). ConclusionScene simulation of medical disputes has an obvious advantage in clinical skills training.
ObjectiveTo investigate the effects of medical simulation (MST) combined with case-based learning (CBL) in training of trainee doctors in emergency department. MethodA total of 120 trainee doctors practicing in the emergency department between March 2008 and December 2014 were randomly divided into two groups:MST combined with CBL group and CBL group, who accepted MST combined with CBL training and merely CBL training, respectively. The training effects were evaluated in terms of theoretical knowledge, practical operation, comprehensive abilities of case analysis and questionnaire survey. The results were compared and analyzed with the t test. The P value less than 0.05 was a significant difference. ResultsTrainee doctors in MST combined with CBL group acquired higher scores in all of the indicators (P<0.05). ConclusionsMST combined with CBL is a feasible method and has a better effect in training of trainee doctors in Emergency Department.
