Val G. Hemming Simulation Center’s Simulated Wounds Are A Cut Above The Rest
Children are limited only by their imaginations when they pretend. Every part of their imaginary worlds - from the city streets populated by superheroes to the musty halls of crumbling castles – is left to their imagination. Grownups can pretend, too, but they often have ways of bringing their imagination to life.
The Val G. Hemming Simulation Center (SimCen) at the Uniformed Services University of the Health Sciences (USU) uses special effects (moulage) to bring to life realistic-looking injuries used to train students and other healthcare providers at the center and medical field exercises.
Operation Bushmaster is a major field exercise where first-year medical students play the part of wounded patients for fourth-year medical students to assess and treat. Eric Singdahlsen, the external programs and hybrid simulations manager at the SimCen, trains about a dozen service member volunteers to apply moulage to the students, who take part in several injury scenarios each day.
Simple moulage application uses makeup to create superficial wounds on the body, like bruises, burns, and abrasions. Larger simulated injuries like compound fractures or amputations require more time and effort beforehand to create silicone prosthetics that must be affixed to volunteers and blended in with makeup. Most “patients” during an exercise can have a variety of small and complex moulage, which together can be very time-consuming to apply.
Betsy Weissbrod, a medical illustrator for the SimCen, designed a method to streamline moulage for smaller injuries through use of temporary tattoos. Weissbrod designs the injuries on the computer, then prints them out onto temporary tattoo paper that can be purchased from almost any store. This saves a lot of time not only applying the moulage, but training people to apply it as well.
“[Using tattoos] didn’t start with moulage; we started with the first-year medical students’ physical exam course. They hadn’t taken anatomy yet, and we were asking them to do a head-to-toe physical exam on a patient. They don’t necessarily know surface anatomy to the underlying anatomy they’re looking at,” Weissbrod said. “We started by painting the students themselves; physically painting on their neck where the thyroid is, or where on their chest are the heart and lungs. We quickly realized that we didn’t have the time to paint the anatomy on the number of students and the amount of time they gave to us, so we made temporary tattoos with the anatomy.”
What used to require hours of teaching and hard work can now be applied in a matter of minutes with a moist paper towel. Even with the tattoos, makeup can be used to further enhance the injuries.
“They did a Halloween-themed event for the public called ‘Bites,’ and it was about different bite wounds,” Weissbrod said. “Some folks came in to talk about animal and insect bites, and the types of rashes and bite marks associated with them, and they asked us to come in and do moulage of them on the visitors.”
