Okie - Why the Narcan?  Do you suspect opiate OD?  I'm not challenging you, just curious.  Youse guys (notice my Philly dialectic 

) have a lot more and updated experience than mine.  I'm trying to wing it on these from memory of my training many moon ago.  Right MR2? Richard?  
I also have noticed youse guys (there it is again 

) don't like blood volume expanders.  This is a new one on me.  Do you have any references to why these are contraindicated.  My first impulse in hypovolemic shock is to reach for Dextran/NS.
I am hoping to get educated here - so bring it on. 
Not that I am likely to ever use these skills again, but these are FUN.  Thanks SDiver!
