Objectives-To determine whether addition of ultrasound to traditional physical examination instruction improves junior medical students' abilities to locate the femoral pulse. Methods-Initial，150名二年级医学生被教导使用传统床边教学标准化患者和在线教学视频的股动脉脉搏检查。然后将学生随机分为2组：第1组先接受超声培训，然后完成标准化考试;第2组先进行标准化考试，然后接受超声培训。在标准化的患者中，在使用超声进行治疗之前，用隐形墨水标记股动脉。与这些标记物相比，学生们随后被评估股动脉脉搏触诊的准确性和股静脉的估计位置。所有的学生完成了自我评估survey后，超声sessions.Results-Ultrasound培训提高了学生的能力触诊股动脉脉搏（P = 0.02）。然而，超声并不能帮助正确估计股静脉的解剖位置（P = 0.09）。在定位股动脉和静脉的信心水平是平等的基线组之间，都增加后，超声sessions. Conclusions，除了超声教学传统的体检教学增强了医学生的能力和信心与股血管检查。然而，解剖学的理解可能需要强调课前教学材料，但需要进一步的研究。
Objectives-To determine whether the addition of ultrasound to traditional physical examination instruction improves junior medical students' abilities to locate the femoral pulse.Methods-Initially, 150 second-year medical students were taught the femoral pulse examination using traditional bedside teaching on standardized patients and online didactic videos. Students were then randomized into 2 groups: group 1 received ultrasound training first and then completed the standardized examination; and group 2 performed the standardized examination first and then received ultrasound training. On the standardized patients, the femoral artery was marked with invisible ink before the sessions using ultrasound. Compared to these markers, students were then evaluated on the accuracy of femoral artery pulse palpation and the estimated location of the femoral vein. All students completed a self-assessment survey after the ultrasound sessions.Results-Ultrasound training improved the students' ability to palpate the femoral pulse (P =.02). However, ultrasound did not facilitate correct estimation of the femoral vein's anatomic location (P =.09). Confidence levels in localizing the femoral artery and vein were equal between groups at baseline, and both increased after the ultrasound sessions.Conclusions-The addition of ultrasound teaching to traditional physical examination instruction enhanced medical student competency and confidence with the femoral vascular examination. However, understanding of anatomy may require emphasis on precourse didactic material, but further study is required.
