Abstract

Ultrasound guidance during centesis is recommended to reduce the risk of serious complications, improve success rate, and to choose appropriate sampling locations and equipment. The aim of this study was to develop an accessible and reusable ultrasound skill simulator for ultrasound guided centesis (USGC). Fifty second year veterinary students reviewed an instructional video prior to performing two USGC skill tests on the simulator, separated by a period of practice. Following practice there was a significant improvement in score ( p < .0001), and average score and time improved by 8.6% and 163.3 seconds respectively. The proportion of successful aspirates improved by 9%, from 66% to 75%. Most post-session survey feedback was positive, and none was negative. Thirty-eight of 49 participants (78%) indicated they would prefer learning this skill with the simulator or in combination with individual practice and/or observation. Ninety-eight percent (49/50) strongly agreed that “this training simulator should be incorporated into the veterinary curriculum,” and 94% (47/50) strongly agreed with “I would use this training simulator again to practice basic ultrasound skills.” Eighty-four percent (42/50) strongly agreed their skills and knowledge improved using the simulator and 82% (41/50) strongly agreed they gained confidence with ultrasound using the simulator. The remainder of the responses for these four questions was agreement, and no student disagreed with any of the statements. The authors conclude this is an effective and well-received simulator for teaching ex vivo USGC and recommend incorporation into the veterinary curriculum for basic ultrasound skill training.
