Teaching Atraumatic Soft Tissue Handling in the Simulation Laboratory: Development of a Novel Training System.

Atraumatic soft issue handling is essential for optimal wound healing. Simulation is a safe and effective way to improve surgical skills outside the operating room. Our primary aim was the development of a pressure-sensing forceps that measures the force applied to a given tissue and provides real-time biofeedback. Seventy-eight students and trainees performed four trials of a continuous subcuticular closure using our Tissue Handling Trainer System device on a silicone skin model. We recorded the occurrence of above-threshold pressure and duration of time over the threshold. A one-way analysis of variance with Tukey post hoc test was used to analyze duration above-threshold pressure. There were statistically significant differences in the duration above threshold from trials 1 to 3 ( P < 0.001). A 36% reduction occurred between trials 1 and 2 after participants learned of the study purpose, but a 70% reduction between trials 2 and 3 with audible feedback. There was no statistically significant difference between trials 3 and 4 ( P = 0.807). The Tissue Handling Trainer System may be an effective technique for improving tissue handling skills in the surgical simulation laboratory.
