I have two words for you: Morphine Drip.
The internet has lots of pages that show you how to re-wire them using things from a toiletries kit (so no need for 'real' tools!). Every four hours? Ha! Try every 20 minutes. Trust me; nothing smothers fear like Mother Opium.
Seriously, think of it this way: hospital's the safest place to be for that kind of thing.
Trust me, I'm a doctor ;P
