I have to triple-support the offers of loaning a DS or portable DVD player (assuming you have it and assuming that you are ready to part with it, honestly saying 'I'd rather it get broken being used than not get used'). If you can't, don't. Only truly bad luck would make it impossible for her to return it, but she would feel AWFUL if it was the case, even though you'd understand.
This sounds like a terrible suggestion, but seriously? I'd go with one airport magazine per hour of surgary, plus 2. She'll mostly look at the pictures, but it will give her something to do with her hands even if she never reads them any other time. I'd go for a variety - Cosmo, Elle, National Geographic, Vogue (get EU and US if you can, the comparision itself is absorbing) - it's light, and even if she's dubious about buying for herself, I'll bet she'll be glad to have them while she's waiting.
