Effects of simulated training for on-the-job physicians' electrocardiogram theory and operational learning effect / 中华医学教育探索杂志

Objective To evaluate the effect of simulated training on in-service physicians electrocardiogram(ecg) theory and operational learning effect.Methods Sixty resident doctors were randomly divided into experiment group (n=30) and control group(n=30).The experimental group adopted teaching + simulation training mode to implement the theory and operation of ECG in continuing while the control group were taught only by lectures.Training effect of both groups was assessed by electrocardiogram theory and operation examination before and after training respectively,and by questionnaires at the end of the training as well.Data of the examination and questionnaires were analyzed by t test or x2 test.P＜0.05 was considered statistically significant.Results After training,the score of theory examination was (90.87 ± 6.67) points in experiment group and was (85.83 ± 5.5) points in control group,with statistical difference between these two groups(t=3.201,P=0.003).Score of operation examination was(93.40 ± 4.31) points in experiment group and was(77.03 ± 7.96)points in control group,with significant differences(t=10.204,P=0.000).The satisfaction degree of enhancing learning interest,theoretical knowledge and operation skill,and strengthening the concept of humauistic care were significantly better in the experiment group than in the control group (x2=34.737,6.405,42.088,41.713,P=0.000,0.011,0.000,0.000).Conclusions Application of simulated training in the study of electrocardiogram is obviously superior in effect to the traditional teaching model.It can improve the theoretical knowledge and operation skill,which is helpful in elevating the in-service physicians' comprehensive capability.

Research progress of iatrogenic vertebral artery injury / 中国矫形外科杂志

Iatrogenic vertebral artery injury is a rare complication in cervical spine surgeries,the consequences of which may be catastrophic.With the extensive development of cervical spine surgeries and application of diverse new internal fixations of cervical spine,there is a potential increase of risk of iatrogenic vertebral artery injury,which should be paid attention to.This article reviews the rate,cause and management etc.of iarogenic vertebral artery injury.
