title: Validation of an effective, easy-to-make hemostasis simulator.
abstract: The purpose of this study is to describe the construction method of a cost-effective, easy-to-make hemostasis simulator and to compare its effectiveness as a training tool to cadaver training. The simulator is made of materials commonly found in hospitals and clinics. These include a column manometer, a 500-ml saline bag, two intravenous fluid lines, a three-way stopcock, and a 6-mm-diameter Penrose drain. The device was tested on 10 final-year veterinary students. All participants tied 40 knots on the simulator and 40 knots on equine jejunal arteries sourced from a local abattoir. They were then asked to fill out a questionnaire comparing both methods. Participants assigned an overall assessment median score of 8.5/10 to the simulator and of 6.2/10 to cadaver practice. The simulator provided reliable haptic feedback, giving trainees a lifelike feel very close to that experienced when actually closing a blood vessel. In addition, it was effective in objectively evaluating students' ability to place ligatures on vessels. After adequate training, students' skills had significantly improved, alongside their confidence in placing hemostatic sutures. This proves our model is also useful in teaching basic open-surgery skills. Finally, its low production cost makes it ideally suited for self-practice.
