Tell whatever you want, surgery is one of the most hard things for me. It's also expensive, and even if you do everything right, it fails. So, my suggestion is :

SURGERY TUTORIAL!

Yes yes, I know, there's a lot of YouTube videos showing you how to perform surgery...But find me a guy who was performing surgery for the first time and didn't fail. That's what I'm talking about! We do have a little guide on Surg-E, but that ain't helpful.

That would be text somewhere, like :
The patient is awake! Use Anesthetic to bring him back to sleep., or
The patient is bleeding! Use sponge to clean it up.

Hope you like my idea,
