"Grey's Anatomy" goes to great lengths to make sure that their medical scenes look as realistic as possible, meaning that they have to get creative with their props to make situations such as surgeries look authentic. If you're curious about the types of things they utilize for props, actor Sarah Drew, who has been playing Dr. April Kepner on "Grey's Anatomy" since 2009, has opened up about what filming those surgery scenes are like including what kind of props they have to work with. Speaking with the Miami Herald, Drew said, "We work with bovine organs, which is cow's organs. The smell is repulsive and makes us all gag. And we use an actual soldering tool to solder the organs. It smells like burning flesh. There's also a lot of silicone and blood matter red jello mixed with blood and chicken fat. It's pretty gross" (via RTE).

Along with making the props look realistic, there is great deal of attention paid to how the actors are moving and acting in a surgical setting to make sure that they don't do something that an actual doctor wouldn't. In September of 2021, LitHub published an oral history in which the cast and crew discuss how they pull off their most intricate medical scenes. Giacomo Gianniotti, who played Dr. Andrew DeLuca from 2015 to 2021, told an amusing anecdote as an example of the lengths they go to for accuracy: "My first surgery was a nightmare. There were so many things, general rules that I didn't know about sterilization, keeping everything clean. I was constantly dropping my hands in surgery and Linda Klein," the show's medical adviser technician, "would be like, 'Cut, cut, cut! Giacomo, what are you doing? You're dropping your hands! You're not sterile!'"
