A couple of things.
1badassEMT-I : I'm saying this in a friendly way. When complaining about being treated like an idiot, you have to understand how things like your screen name, and the fact that the some of your posts read like they have been typed by someone having a seizure, instantly impact upon people's perception of you. Without any previous experience of you we are presented with these things:
-a questionable screen name
-shockingly typed and thought out posts. (To the extent that, I at least, have been unable to divine the meaning behind about 30% of your posts.)
-Posts full of what I will tentatively term whackerisms (constant references to saving a life, a dim view of education [although I find it hard to tell what you position actually is], excessive references to equipment, dogmatic application of protocols, overly simplistic appraisal of clinical issues etc].
When you then present a questionable idea as a basis for an argument you are making, don't be shocked if people want to pick that idea apart. This would be true in any case, but given the above, you can imagine why people are especially keen to deconstruct you thought processes. That is, after all, the only reason why I and many others come to this forum - to examine ideas. Now I'm not saying you have to change your screen name or anything, but just consider the affect of all these things taken together.
The scenario: I can except that a person had a hypersensitivity to morphine and that they subsequently suffered a reduction in resp rate and conscious state. If you are going to say arrest without a qualifier, I don't think it is unreasonable to assume you mean cardiac arrest. Also the whole point was that the IV line was necessary for the immediate saving of the patients life, hence lines are needed before morphine (the presence/action of SJW is essentially irrelevant). I think we can safely say that notion has been debunked. You seem to accept this. So why base an argument on it in the first place? Can't you see why some people are taking issue with your thought processes?
I have also heard that SJW may mildly increase the effects and duration of opiates, but you have yet to provide any reliable references. Where do you think an article on About.COM fits into that hierarchy? Come on mate, If that's what you're going to post as reliable evidence, you're going to have to get used to people taking issue with your posts.
