Development of a Field-Expedient Vascular Trauma Simulator.

The past few years have noted significant declines in combat casualty exposure over the course of a deployment. As a result, overall confidence and comfort in performing potentially life-saving therapies may wane during a deployment. Development of training simulators provides a method for bridging this gap. Herein, a field-expedient vascular trauma trainer for noncompressible torso hemorrhage is described. A low-fidelity simulator was created using a Penrose drain, intravenous tubing, suture, and a cardboard box. A higher-fidelity simulator was created using an aortobifemoral bypass graft, double-lumen endotracheal tube, suture, and an upper torso mannequin. The two trainers were successfully used to train for peripheral shunt placement and definitive vascular repair. The trainer makes use of supplies readily found at most Role 2 and 3 facilities and that are obtainable for Role 1 facilities providing damage control surgery. It provides a just-in-time way to develop and sustain confidence in the damage control principles applicable to vascular injuries.
