Generally speaking, hospitals are going to pull field-start lines on admitted patient, including those going for surgery, unless the patient is going to require urgent/emergent surgery upon arrival. This is because they cannot control the procedure/policy that you follow for ensuring as clean insert of the line as they can within their own facility and if another facility started the line, it is properly documented and such that proper procedure was followed. In short, they're not going to trust your line and therefore they'll pull it ASAP. As an ED RN and previous Paramedic, I will test and verify that a field start IV is patent before I'll use it. I'm also not going to pull an existing line until I've placed a new one. That being said, by you placing a line in the AC, you've basically removed a lot of potentially good sites from consideration at the other facility. Most IV lines I place aren't in the AC. They're usually in the wrist, hand, or upper forearm, just distal to the AC space. If you've blocked all those with your AC-placed line, I'm going to have to do an USGPIV if I need to pull your line.
Something also to consider, the receiving facility knows what vascular access the patient has. This is one of the things that is discussed during the RN-RN report. If they're OK with a 22g in the AC and I don't expect any additional need for vascular access, I'm sending the patient with the 22g in the AC. There have been times that I've been asked to place a 2nd line (and sometimes a 3rd line as 2 are already in place) before the patient leaves my facility. Otherwise I expect that they'll place an additional appropriate line if it becomes necessary. Another thing that will be discussed (and probably brought up in report to you) is whether or not that other arm is available for IV lines. I have seen some wonderful veins on a given side but can't place a line on that side because doing so is contraindicated.
Sometimes I'll place another line in the ED because I know the patient is likely to get (or has orders for) medications that are Y-site incompatible.
