Development of a Balloon Tamponade Task Trainer

Abstract

Variceal hemorrhage is a life-threatening complication of patients with cirrhosis. If a patient is hemodynamically unstable and unable to undergo endoscopic therapy, a balloon tamponade device may be placed to temporize the hemorrhage until definitive management may be performed. Placement of these devices may be performed by practitioners of several different medical specialties. Placement of balloon tamponade devices requires multiple steps and several different pieces of equipment. Performing the procedure incorrectly can lead to iatrogenic injuries such as esophageal necrosis or perforation. Since this is a relatively rare procedure often placed under high-stress situations, practicing in a low-stakes setting, such as a simulation lab, allows practitioners to hone their skills. Commercially available task trainers for balloon tamponade device placement are not available. In this paper, we describe how to modify an inexpensive airway task trainer for this purpose using commonly available and cost-effective materials.
