Probably sterilized the drill bit with alcohol or iodine. Maybe if
paramedics had a simple drill handly, they could've saved Natasha Richardson
and others with rapid brain swelling. Just like having emergency
defibrillators ready-to-go in public places. Seems like a basic, useful
emergency procedure for those adequately trained to recognize obvious signs
of brain swelling when there's not enough time to get to the hospital.
