Bringing damage control surgery simulation to life: developing a novel surgical anatomy model within immersive...

Haemorrhage from junctional injuries remains the most common cause of battlefield death. Changes to surgical training have meant acquiring and maintaining trauma surgical skills is becoming more difficult for military surgeons. The multidisciplinary Military Operational Specialist Team Training (MOSTT) course is designed to bridge the gap between civilian practice and the deployed environment, as part of predeployment trauma training. It involves immersive team simulation and uses cadaveric dissection for surgical skills practice.A novel surgical anatomy model, featuring junctional haemorrhage surgical task trainers of the groin and shoulder, was designed using reconstructed CT and MRI images obtained from a human volunteer. The model is designed to look and feel as realistic as possible, with the added dimension of pulsatile 'blood' flow from a simulation gunshot injury.This surgical anatomy model has been trialled, as part of the MOSTT course, by 90 surgeons and perioperative practitioners, with feedback analysis used for iterative model development. Feedback demonstrated that, alongside more traditional cadaveric dissection, this surgical anatomy model adds value to current predeployment training delivered within the immersive simulation of the MOSTT course. Research by the authors about the effects of this model on surgical ability and performance is ongoing. However, there is clear potential for this model to be used in other environments, including on exercises and as part of consolidation training while deployed.
