Here's a neat trick I learned a while back. We carry small towels on our ambulances. My partner drives like a maniac. So when I get a pt who is suffering from N/V, I put a small towel into the emesis basin. That way, when the pt vomits into the emesis basin, the towel helps to soak up the vomit and it doesn't splash out when my partner takes a sharp curve at 60 mph. Also, if my pt drops the emesis basin, I won't have nearly as much to clean up.
