Central Venous Catheter (CVC) questions

I have a quick question. I just started working at a hospital and was recently transferred to a new unit.
Based on my previous experience in a different department, just because a patient has a central venous catheter (subclavian) doesn't mean they need to be on a continuous infusion from hour zero to twenty-four. You flush the line regularly, sure, but once an infusion is finished, you can close off the catheter so the patient isn't tethered to their bed constantly.
To make a long story short: today, after an infusion wrapped up, I closed off a patient's catheter. Suddenly, all hell broke loose. Apparently, if the catheter stays closed—meaning no infusion is running—for more than 15 minutes, the patient supposedly has to go back into the OR to have a new one placed.
Does this really imply that anyone with a CVC has to be on a constant drip?
I’ve been digging through some medical journals online, and everything I find suggests that you absolutely can close the catheter. But just to be safe, I wanted to ask if anyone here has dealt with this before. I would really appreciate any insight. 🙂

Based on my previous experience in a different department, just because a patient has a central venous catheter (subclavian) doesn't mean they need to be on an IV drip from midnight to midnight. We flush the catheter regularly, but once the infusion is finished, you can close it off so the patient isn't constantly tethered to their bed.
To make a long story short, when I closed a patient's catheter today after her infusion finished, it caused a huge commotion. Apparently, if the catheter stays closed (meaning no infusion is running) for more than 15 minutes, someone claims they have to go back into the OR to reset everything.
Does that actually mean anyone with a CVC has to be on a continuous infusion?
I've been scouring the web and found articles suggesting the catheter can definitely be closed, but just to be safe, I wanted to ask if anyone here has dealt with this. I’d really appreciate some insight. 🙂

Maybe the issue is specifically what kind of IV medication was being administered.

Look, a CVK is there when you need it, not some constant IV drip. The whole point is making sure the catheter gets flushed regularly with heparin or saline so it doesn't clog up. Think about it—if someone’s on a continuous infusion they don't even need, what are we actually doing? Are we just flooding them with saline? How many liters of fluid would a patient end up getting if they were stuck in the hospital for a month? Plus, how do outpatient dialysis patients manage without their lines clogging up every three days? Honestly, just go ask your head nurse those questions. I'd love to hear what kind of answer she gives you.

Hey there... I know more than a little bit about what it's like dealing with a CVAD. My little guy had one implanted when he was only a month old because he had to start chemotherapy. They actually just finally took it out, and he's thirteen months old now. Back when he was undergoing chemo, he wasn't just getting the drugs—he was on constant infusions too, so he was basically hooked up to something twenty-four hours a day. Honestly, whenever we were staying at the hospital, he was tethered to a machine or a line. There were times when they’d let us head back home to our place in Chicago for a few days just so the little guy could catch his breath and reset before the next cycle started. Since it was such a tiny catheter, we’d have to drive right back to the hospital every couple of days just to flush the line. It really all depends on how big the catheter is, but for him, we were doing this routine every other day. To flush it, they take 100ml of saline and mix in two units of heparin. First, they push one unit of that solution into the catheter, then they draw out two units of blood—which gets tossed out—and then they finish by flushing the whole thing with five units of the solution before closing it off. That was just our life, every two days, over and over again.

I was wondering, what’s the actual protocol when someone's coronary artery gets totally blocked—like, when it's too obstructed to even attempt standard therapy?

So basically, you just bring in someone new and pull the old one back out of retirement.
