Objective To evaluate the effectiveness of echocardiography teaching in the standardized training of anesthesiology residents. Methods Residents in the First Affiliated Hospital, Southern University of Science and Technology who took part in standardized training were selected. They were trained on the basis of four basic views, including left ventricular in‑flow and out‑flow tract, right ventricular in‑flow and out‑flow tract, left ventricular short axis and apical four‑chamber view. According to the times of training, the residents were divided into three groups: a blank group (without being trained, n=7), a control group (being trained once, n=10) and an experiment group (being trained more than once, n=14). The distribution of residents in each group was observed. The number of people whose four basic views were accurately collected by a model was recorded. The number of people who were all or 50% correctly diagnosed with one of six types of clinically simulated hypotension during the perioperative period (including heart failure, pericardial tamponade, insufficient blood volume, severe aortic stenosis, aortic dissection, and abnormal left ventricular anterior wall motion) were recorded. Results There was no statistical difference in the distribution of residents in each group on different grades (P>0.05). The number of residents in the experiment group who correctly collected four basic views was higher than that in the control group (P<0.05). There was no statistical difference in the number of people who were correctly diagnosed in each group (P>0.05). The number of 50% correctly diagnosed patients in the experiment group was higher than that in the control group (P<0.05). Conclusions After training twice, residents can collect four basic views of echocardiography with a higher accurate rate. Echocardiography can be adopted to diagnose perioperative hypotension simulation cases, with a higher accurate rate.
