不同经胸心脏超声模拟器在麻醉住院医师教学中的比较

Objective To evaluate two different kinds of simulation-basedTransthoracic Echocardiography (TTE) training effect and against traditionaltraining on TTE skills among anesthesiology residents; Methods In our study, 63anesthesiology residents were randomized to 3 groups, simulation 1 group (n =21),using Heartworks simulator simulation 2 group (n = 21)using U/S mentor simulator; and control group(n = 21),using traditional teaching method. A pretestwas done before TTE training. Firstly before training, members in all groups accepteda written test to access their pre-training knowledge of TTE. And after training,a similar written test was carried out again. Beside, TTE practice examination onvolunteer models were adopted to evaluate the teaching result, including the abilityto acquire correct images and to identify the anatomy structure; Results Therewas no statistically significant difference on the pretest results among theseresidents of the three groups. After traininghowever, the two simulation groupsgot similar grades but higher than the control group on all the three indexed: writtentest (53.8%12.6%52.6%13.6% 43.3%10.8%P<0.0167), model image quality (0to 25 scale) (17.14.516.04.17.73.1P<0.0167), and structure identification(0 to 25 scale) (18.26.317.06.111.96.9P<0.0167); Conclusion Our studyshowed that in TTE teaching, anesthesiology residents trained with both kinds ofsimulations acquired better knowledge and skills of image acquisition and anatomyidentification on volunteers.
