I was taught to hang NS, and the protocol where I worked then, as well as the protocol where I work now, is NS, however, I also work part-time at another service which has D5W in their protocol, so when there, I use D5W.
The reason for posting this in the first place was to bring up the fact that there seems to be no standard being taught that is consistant from one school to another.
When I was a paramedic student, this same Paramedic asked me what fluid I'd hang when administering D50, and when I told him NS he threw Hell. And when I informed him, as did one of my classmates, that we were taught to use NS, he informed us that we as well as our instructor were idiots. He even went on to call our instructor and raise hell with her.
Our current crop of students are being instructed to hang D5W, and one of them questioned me while riding along, when I hung NS.
Anyrate, still waiting for Dust to slip in, tell us all Paramedic schools suck, grumble a bit, and then enlighten us all.
I've scoped this out on the Net, read all the pros and cons I could find, and still don't have a definite answer as to which is best.
