Usually they just say "this vein is really thrombosed." That's when Sparkles would say something. Now she tells them beforehand, saves loads of pain.
Best philosophy in SWIM
's opinion. At least where labs and emergencies are concerned. SWIM can usually tell when someone has best a past or former addict
--or they have a verifiable medical history of severe, prolonged illness with lots of vascular cannulations.
If someone tells SWIM they are/have been a banger in the past and she's not seeing or feeling any veins jumping out at her, she'll listen to them more often than not...or at minimal explain why she isn't(the need to use a larger catheter than the vein can accomodate).
It should be noted however that in the cases of trauma or any potential surgical case or inpatient admission hospital staff os NOT going to want to use a "butterfly" for IV access. While alright to draw blood(barely--lots of times red cells will hemolyse because the needle diameter is too small making the sample completely useless). They're not appropriate for these patients. If theres any chance blood may need to be given at some point, they're going to want to establish an IV with at LEAST an 18g, preferably a 16 short for trauma or medical patients that may need blood products or rapid infusions. For general admissions, at least a 20-22g because small diameters are correspondingly harder to keep open and patent.
Alternatively, for lab techs and routine bloodwork--one can tell them the once had an extended hospitalization due to accident or whatever and it did a number on their veins(techs dont have access to ones medical info). However, note that they are generally loath to use butterflies on adults as more than half the time it renders the collected specimen unsuitable as it destroys the cells die to the small diameter of the needle.
Trust SWIM, most, 99%, of medical provider do NOT want to have to stick Swimmers any more than absolutely necessary. Not only do we loathe poking someone ten times or having to "fish" around for a vein...but taking that much time to complete what should be a rather quick procedure backlogs all the other things we should be doing up.
On the other hand, SWIM has seen new lab techs going for tiny veins they could visualize...rather than a big, huge, bouncy and obviously patent antecubital that could be clearly felt, but not seen. This is ridiculous. If one gets a tech that unsure of themselves and they know they're a hard stick and that tiny vein they're eyeing is going to blow if they so much as even look at it wrong--dont be afraid to (politely) stop and nicely re-direct them to a palpable vein. People with newly acquired IV skills are generally loathe to use veins they can't see.
SWIM actually doesn't have any visible track marks, except for 1 small faded one on the outside of his wrist which will probably disappear soon. No other scars though besides ones from "legitimate" injury.
Hell, that can be explained by a gung-ho medic sticking SWIY with a 16 or 14g. SWIM still has a cannulation scar from a 16g into her left interns vein that was placed for a few hours for rehydration during a search and rescue operation in 2001.
