As usual, @RFDSDOC gives out good advice, literature and proves he is a guru. This time he looked at pre-hospital analgesia and trauma. Make sure to check out his page at: Prehospitalmed.com
Now back to the article on morphine and ketamine being better than morphine alone:

I routinely use this combination of morphine and ketamine for trauma pain control. I also liked that the article gave realistic advice on doses and titration.
Thanks for bringing this up @RFDSDOC!
