With regards to neck trauma/anatomical issues - the IJ isn’t the only site available for a CVC. Usually can get a line in SOMEWHERE - but I have had 1-2 cases where our vascular surgeons and IR docs weren’t able to get a line in either - including a picc. This situation is rare. The optimal site is also variable depending on who you talk to - subclavians have least infection and most mechanical complications - femorals have most infection - IJ is in the middle. Where I did residency we did mostly IJs, in fellowship we did a mix of IJ/subclavians - subclavians were preferred.
With regards to PICCs for pressors, if someone already has one, I see no problem using it. Why subject them to another central line when we already have a “peripherally inserted
central catheter”? In the same way I have no problem using port-a-caths for pressors. Unless they need a CVC for other reasons.
The logistics of placing PICCs for acutely ill patients are also problematic, most of the hospitals I have had the chance to work at have either picc nurses do it at bedside or IR docs/midlevels putting these in under fluoro - and they are usually extremely busy. It would be hard to squeeze in sick patients who often need access right away.
The other part is the number of lumens. PICCs usually have one or two. A real CVC is usually triple or quad lumen. Another thing to consider is the length of the line - PICCs are much longer catheters in length compared to CVCs. If you are trying to resuscitate someone quickly, it’s generally much faster to give it through a CVC/cordis than a PICC.
Putting in PICCs for the purposes of vasopressors is not my practice. I have seen it being done and I don’t think there is great literature for or against it. There is a paper that just came out relating to this which concluded that “Peripherally inserted central catheter use in the ICU is highly variable, associated with complications and often not appropriate.” (Link below)
