in fellowship I believe we always used a brand new 10ml Omnipaque bottle on each patient. We never multi dosed.
Of note, I'm currently in a hosp based practice and have a 20ml Isovue contrast bottle that I open for each patient. Here are my reasons:
1) If you didnt draw up the medication, you have no idea what's in it. Additionally, and this was in a ASA newsletter a few years ago.....if your pain procedure door is open you never know who is trying to sabotage your meds (competing docs, a ticked off RN, terrorist,whomever....) IF you draw the med up you know exactly what's in it.
2) An attending also once told me this. If you multidose a vial that's supposed to be single dose (that's what it says on all Isovue bottles), and unfortunately something were to happen. Let's say arachnoidits,infection,etc. A root cause analysis may take place. If the patient or hosp/you sue the manufacture for a defective product. Let's say you claim that you used sterile techinque, masks,etc and now defferred the blame to the contrast/meds. They will try to find out what you injected and how much you drew it up,etc. IF they find out you had multi dosed a single dose vial, then you have no leg to stand on.
3) I believe this year it's mandated by CMS . I've been getting all those emails from ASIPP stating stating to fight this push for single dose of these meds
4)what would you do for your mom? Let's be honest, if money WASNT an object, how would you want your mom, dad, loved one to be injected. Wouldnt you want a single dose vial that you opened up? Not something that was sitting on the table opened by a RN, 5 hours ago, and was out of their site periodically throughout the day? There are just too many variables.
Again, I practice at a hospital where they pay for these supplies. I might be a little biased as a result. Regardless, of what we think on this matter it seems like CMS and JCCHO will mandate this anyways...
