We propose to develop surgical simulations for training military and civilian personnel in critical trauma procedures. The objective of this effort is to provide a degree of training and evaluation of performance that is not possible with existing technologies in trauma management in the battlefield and emergency room. Phase I of this project involved the establishment of content and design specifications for critical trauma procedures. As a demonstration of the utility of the software, we have authored a prototype virutal reality simulation of the placement of a central venous line in the subclavian vein. This simulation incorporates visual and tactile realism of the actual surgical procedure, providign a genuine scenario for teaching physicians central line placement. During Phase II of the project we will: (1) Produce a 'Trauma Simulation Suite', containing prototype simulators for: central veous access (femoral and jugular), endotracheal tube placement, chest tube placement, and reduction of shoulder dislocation; (2) Evaluate the training efficacy of the 'Trauma Simulation Suite', including anatomy, procedural substeps, mistakes and complications, the development of appropriate motor skills, proper handling of instruments and time and precision requirements of the procedure; (3) Modification of the 'Trauma Simulation Suite' using information obtained from the Evaluation phase.
