Great thread! I love reading the tips.
I've started using the PCV two-handed mask quite a bit this month -- doing mostly vascular and our "OR of the future" hybrid angio suites have a really awkward layout from an anesthetic POV when the room is flipped to angio the legs -- you end up having to squeeze the bag with your left hand (and the machine is at the patient's waist) and hold the mask with your right. I've started just setting the vent and using two hands. It's awesome!
A few T&Ts from a CA-2 (obviously not a ton of experience so take it with a grain of salt):
1) Agree with the continuous epidural technique. Our institution is mostly intermittent and an attending showed me continuous and it was life changing. Especially for challenging epidurals it has cut my time down at least 50%. I use glass syringes with saline and a tiny bubble in the end of the syringe. Right hand on the syringe applying pressure, left hand on the shaft of the needle (not the wings) "feeding" the needle in like you would a catheter. I've probably done 75ish each way and I can say the continuous technique is far superior in my hands. YMMV.
2) For PACs, if you get to ~50cm and still haven't hit RV (aka you're headed south down the IVC), drop the balloon and pull back slowly. I've had several PACs flop through the TV on their return trip through the RA while pulling back - then put the balloon up and advance.
3) Central line wire won't go -- I had this happen to me for the first time the other day. Stuck with thin-wall, visualized in vein with u/s but wire got hung up. I assumed I was out of the vein (through and through or whatever) and took wire out but could still aspirate. Wire still won't pass. I pulled out and went ~1cm north, stuck again, again easy vein access, same story - but I noticed the wire was getting hung up ~15cm (so it was out of the bevel of the needle, not like it was getting stuck at the end of the needle and I wasn't intravenous). The RN scrubbed with me (we have a dedicated group of CCRNs who scrub all our lines / PACs / etc and prep / hand us stuff... I know, I'm spoiled) told me to try threading the 18g long angiocath (used for manometry) over the wire, which I did and then was able to advance the wire past the stenosis I was hitting. Later w/ ultrasound I scanned way down and pointed the probe intrathoracic and you could see some stenosis of the IJ proximally that I think was causing my wire to kink. Apparently it's a trick she's employed several times over the years when you have a wire in the vein but it won't advance past a certain point. We later floated a PAC on the patient and the PAC also required some finagling to get through that same spot. Weird.
4) For u/s guided PIVs, alines, etc: don't take the needle out of the catheter when you get a flash -- as a matter of fact, I never even look for flash on my u/s guided lines -- look at the monitor the whole time. The only time I see the flash is when I look down at the end. I do short axis out-of-plane approach and "follow" the tip of my needle in the vein until I've hubbed the whole thing - with the needle still in situ (as opposed to a regular PIV where you thread the catheter off the needle after advancing a few mm). The only time I don't do this is if the vein takes a big bend or bifurcates making it anatomically too challenging to keep following it under u/s. Definitely increased my success rate. Also for u/s guided alines don't just poke through-and-through, follow the artery a-la an u/s guided PIV. It helps for really bad vasculopaths (increases the success rate of the wire threading as opposed to through-and-through) and it's good practice for PIVs.
Here's a question for those with a lot more experience than me:
Is anyone using the arrow long a-line kits to access the basilic vein above the AC fossa in patients with poor peripheral access? It's often big and juicy in patients with otherwise poor access but unless they're rail-thin it's too deep for regular angiocaths (you can sometimes hit it but there so little catheter in the vein it's super high risk to infiltrate). I feel like with the arrow it's a poor man's midline (especially since getting a PICC on the weekends is like pulling teeth - and forget about it overnight). If anyone's doing this, are you doing it sterile or semi-sterile or just clean like a regular IV? How long are you leaving these in? Any issues with median nerve hits?
Thanks again for the thread - keep 'em coming!
