nothing short of a miracle. others credit the great medical care and maybe it's a bit of both. dr. sanjay gupta had a chance to talk exclusively to the doctors that were involved in her care. he actually got to visit the critical care area where she was and talked to one of the first doctors to see her when she was wheeled in. >> and the first thing i did was walked in the room. some things were occurring. and i think i said this before, but my first response was i grabbed her hand, leaned in to her and said, miss giffords, you are in the hospital. we're going to care for you. please squeeze my hand. and she did. >> i mean, is she -- does she have a wrap on her head? can you see the wounds at this point? so you have some idea what the obvious wounds are, but you look at the rest of the body to make sure, for example, she doesn't have another gunshot wound, right? >> that's part of the trauma work-up and evaluation. you never assume just what you see is all that is present. i saw the severe head injury.
