general anesthetic seems extremely out of place for a simple subdermal hand surgery. I’m confused by this approach, since IV anesthetic carries its own risks that are not insignificant.
Unless this was “twilight sleep” (by design), that is a serious indication that you may need a big red sticker on your medical record. Definitely talk to your surgeon and anesthesiologist about this because if this was not on purpose, then you may need alternative drugs to achieve the desired effect - feel and hear and experience nothing. Unless this is sorted out, you are at risk of undergoing major surgery without proper anesthetic sleep.
