no, she'll be fine. I recommend tossing out any soiled bedding and washing her off with a little unscented soap and water, because entrails are nasty and the smell lingers. But it shouldn't be a health concern for her.
(F/T exploding happens when either the rodent wasn't completely fresh when it was frozen, or because the rodent's stomach got too hot for too long during the thawing process. The stomach and intestines are full all kinds of bugs and juices and they produce lots of gas and acid when they are revived and heated. It speeds spoilage of the prey item, and it's why human hunters throw that stuff away when they clean animals, so that they have a little extra time to get the meat to the freezer. Snakes eat their meals whole, so they need to eat it freshly-killed to avoid spoilage.
But a little exploding won't hurt her. It's just gross and messy. Next time it happens, you really don't need to wash her mouth out. It's enough to wash her externally.)
EDIT: Oh, and never put antibiotics in her mouth. External use only!
