Q: Who’s still prescribing 0.45% saline for rehydration?

Me … well, actually I don’t anymore, but that’s mainly because I don’t do rehydration. I tend to do hyperhydration to stop the methotrexate causing any more damage than I know it’s going to.

BUT if I did prescribe any fluids for a dried up sprogling, I’d reach for 0.45% saline with a sniff of K+. Am I doing it all wrong?
A team from The Netherlands has grasped the nettle and begun to but some evidence together to argue against a hypotonic perspective: anyone got any views out there?
