If you aren't used to doing such things, I'd have to suggest that you imply the violence. A couple of my completed manuscripts deal with war, and there are many deaths sprinkled throughout them (literally hundreds) though only a certain parts could the violence be considered explicit. It depends on the character's state of mind--is it the first time they've been confronted with this kind of violence? Have they been through a traumatic experience beforehand? Then again, you also have to consider (I say this all the time, I sound like a broken record) the nature of your story. I'm not, nor have I ever been, one to censor myself or others based on whatever standards may exist, and I don't believe anyone else should either.
It's important to note that implied violence can work just as--if not more--effective than explicit details. Scarface and the original Texas Chainsaw Massacre have been considered gory (Scarface for the infamous chainsaw scene and TCM for Leatherface) for years, although in neither movie is there ever a since explicit depiction of gory violence. In Scarface, you never see the chainsaw going through the arm, and there is only a brief splatter of blood from off screen, while in TCM Leatherface hits someone over the head with a mallet and hangs a girl on a meat hook, yet no real blood and they are brief instances. Despite this, they have been thought of for decades now as gory.
