Study ObjectiveTo determine the effectiveness of a short educational video and simulation on improvement of ultrasound (US) image acquisition and interpretation skills.DesignProspective, randomized study.SettingUniversity medical center.Subjects28 anesthesia residents and community anesthesiologists with varied ultrasound experience were randomized to teaching video with interactive simulation or sham video groups.SubjectsParticipants were assessed preintervention and postintervention on their ability to identify the sciatic nerve and other anatomic structures on static US images, as well as their ability to locate the sciatic nerve with US on live models.Main ResultsPretest written test scores correlated with reported US block experience (Kendall tau rank r = 0.47) and with live US scanning scores (r = 0.64). The teaching video and simulation significantly improved scores on the written examination (P < 0.001); however, they did not significantly improve live US scanning skills.ConclusionsA short educational video with interactive simulation significantly improved knowledge of US anatomy, but failed to improve hands-on performance of US scanning to localize the nerve.Copyright © 2014 Elsevier Inc.
