 My name is Morgan Macmonagall. I'm a vascular and trauma consultant. So trauma surgery relates to managing patients who have suffered a severe injury from an external force or a burn. And the external force could be anything from a road traffic collision or a fall from a height or even a fall from standing and also penetrating injuries such as knife crime or gunshot wounds. Unfortunately because of the knife crime problem we are seeing a lot more stabs to the chest. And a thoracotomy or opening the chest for major bleeding inside the chest is one of the areas that we have focused on as trauma surgeons. We have an in-depth clamshell thoracotomy procedure shown on the surgery platform. I think we've managed to marry together both live cases with illustrated and simulated cases in the digital platform to really teach the surgeon what the critical steps are and also to become more familiar with the anatomy. The anatomy can be quite blurred because of all the bleeding in the way and by using both the digital illustrations with the live cases I think is a very very important learning tool for all trainees but also for consultants who don't open chests very very often. They can also learn how to go and something that they can remind themselves over and over again until the next case comes in. My name is Judith Thompson and I went to medical school here in London at Imperial College. I find the app really helpful when the patient is being anesthetised and you know that you're about to scrub in with a consultant and they're going to be quizzing you on the case or you're not going to understand what they're doing as you go through different layers and identifying different anatomical landmarks. So I find the app is really helpful just as a quick revision while they're putting the patient to sleep have a quick look at what the main steps are, what the main anatomy is going to come across is and have an idea of what the critical steps are going to be.
