Aug 8, '09Quote from Woodenpugonly someone who uses IV access for recreational use could come up with an answer like that :chuckleI had once worked with a population of patients who used I.V. access for recreational purposes.
I asked many questions, such as why insulin needles (they call them orange caps). I even asked "why not use an artery?", since you have so few veins left? The answer - I don't think it would be as much fun if my hand got high.
Aug 8, '09Quote from suizzzBasically because there is no good reason to do so, and plenty of good reasons NOT to.Thank you for your sharing.:1luvu:
I just want to find out why cannot give IV med. arterially?
It must be a reason there, isn't?
Because of increased risks of impairing circulation, inadvertant embolization or excessive bleeding, nurses do not routinely access an artery unless specially trained and for procedures that cannot be done any other way (dialysis/ABGs). As it is much less likely to have the same problems from intravenous infusion (less chance of bleeding profusely/uncontrollably, of permanently impairing circulation or embolizing air).
Second, most arteries are either hidden or placed where there are are a lot of nerves. I believe this is G-d's way of protecting us....we tend to in nature keep strangers away from those areas and those generally hurt a lot to access (other than the neck, which we tend to instinctively protect. Arteries tend to be deeper than veins and harder to get to except wrists, groins, etc. areas that have a lot of nerve endings.
Aug 8, '09I think that anyone who has ever tried to draw an ABG understands the difficulty in accessing an artery. All other (good) reasons aside, imagine trying to inject a small hose into a larger hose that has the water running at full pressure without spilling any of that water.
Aug 8, '09For me the obvious answer is that IV stands for intravenous.
Also whenever I think of artery or vein-
artery=away from the heart (to gain arterial pressure (ABP) or arterial blood gas-for example)
vein=to the heart (into the circulation)
I have NEVER heard of instilling any meds into the artery-I used to work in a trauma ICU-maybe things have changed.
Aug 8, '09high pressure and the difference in location (artery = deep) and anatomical structures between artery and vein. veins are lesser in pressure and easily accessible

Aug 8, '09I think I should change the question.
Let say there is a patient with arterial line for ABP monitoring, what will happen if you administer medication to arterial line?
Aug 8, '09Quote from work&playReally? Why don't you go back to your medical dictionary and learn how to spell.IntraVENUS???? Go back to your A&P book and read the difference between artery and vein. Tissue type, oxigen, direction of blood flow.
Geez, can people ask a question without smart remarks. The OP knows what IV stands for. S/he wants to know why veins are the preferred site than an artery and it's quite apparent that those who answered 'because IV stands for intravenous' don't know themselves.
Thanks for all those who explained the real reason(s) why arteries aren't used. I knew at least one reason, suspected anohter, but learned a lot more.
I love these types of threads. Sometimes it's the newbies that teach us a thing or two.

Aug 8, '09Quote from MedSurgeMessActually, I prefer Intraosseous.only someone who uses IV access for recreational use could come up with an answer like that :chuckle

Just found that out today. This doesn't sound like a common practice though.....
