(Inspired by recent talk)
Skilled proceduralists are often asked to help other providers/teams, such as placing a tough line. Here are some important points for this. It is NOT the same as doing procedures on your own patients. (🧵):
1. You are asked to "help," usually verbally, but you're still responsible for your own care. So this is actually a consultation of sorts. Does the patient actually need what they thought? Usually they know their problem ("we need access") but not always the best answer.
They also may not be aware of all relevant contraindications or technical obstacles... or they may simply not care. In other words, they're expecting YOU to consider these. If you do something dumb, you can't just say "well, someone told me to do it."
So inspect the chart and read over the patient's history. Note their med/surgical history. Consider glancing at imaging to be aware of the status of their vessels and presence other hardware.
Note their labs (coags, platelets, renal function, etc), meds (how many infusions? do they need to be central or no?), and overall plan (how long will the patient be here? are other measures planned, such as a a PICC, dialysis, etc?)
2. What about consent? It is a common courtesy for the primary team to handle this, but that may not be possible or even appropriate if they are not trained to do the procedure. While a bit annoying, expect you may need to do it yourself.
3. Ask how urgent it is to plan your own day. If not urgent, i.e. you were asked to help with something a while ago, when you're ready, check at the last minute if it's still needed. Things change; someone else may have done it, the plan shifted, the patient is CMO now, etc.
4. Follow up, at least to some extent. This is not your patient, but you should know about complications of your procedure, how successful it was, etc. Even if the primary team does so too, always confirm your own line, look at the x-ray, see how dialysis is flowing, etc.
5. Be gracious. These requests can be annoying, but ultimately someone's asking for your help because they need it and you can provide it, not to ruin your day. "Will it help the patient?" and "Is it the best solution?" should be your only questions.
(Secret caveat: more broadly, Kant's Categorical Imperative may apply, e.g. even if it helps this patient, does it set broader harmful precedents? E.g. if I start placing IVs on the floor, is that going to become my full-time job? But try not to let this dominate your thoughts.)
Bonus points: I also try not to do this unless discussed with the primary team (versus, say, scuttlebutt via the nurses)... and I try to write (e.g. in the procedure note) who asked me to do it and why. Otherwise there may be no documentation why you laid hands on this patient.

A good thread with thoughtful discussion of the idea of anesthesiology "backing up" other departments (e.g. ICU, ED) in their own efforts to manage airways. Knotty issues, but a few general observations (🧵)...
A patient suffers STEMI causing biventricular failure, including severe RV infarct. An Impella is placed, and they arrive in the ICU from the cath lab. You see the following. (This arterial line is functioning.)
In this case, the Impella is completely decompressing the LV and taking over its output. There is NO pulsatility to the arterial flow — only laminar flow from the Impella. Can you think of any implications of this for the immediate resuscitation?
1. PULSE oximetry will not function. Absorption or reflection oximetry relies on detecting pulsatility to differentiate arterial blood from other blood and tissues (that’s why it gives you a pleth). You will need to rely on blood gases.
When flow dyssynchrony occurs in VC modes, the first reaction is often to increase the flow rate. Reasonable… but it often fails! Why? Maybe because any fixed (or fixed decelerating) flow can have trouble matching the patient effort at all stages of inspiration. Example:
Here the flow starvation occurs in the latter part of the breath, not the start, creating a biphasic appearance to the flow curve. What if we simply increase the flow?
It’s no better! Now flow is probably too high at the start (initial flow overshoot as evidenced by the steep pressure spike)… but still inadequate at the end. Also, the pressure spike and resulting short I-time contributes to some double triggers.
Michae Levy on refractory VF: resuming immediate compressions after a defibrillation shock may in some cases induce refibrillation after initial (unnoticed) ROSC, due to the mechanical stimulus. #CCPRFSummit2021
Double sequential defibrillation may work, but just changing the vector (moving pads) may work as well.
Daniel Dante Yeh: In first 7 days of critical illness., hypocaloric (<70%) nutrition should be used, can advance to 80-100% after day 3. Use indirect calorimetry if you can. #CCC50
Use high-protein, hypocaloric feeding in obese patients to preserve lean mass while not overfeeding. If 30-50 BMI use 11-14 kcal/kg actual bodyweight, if BMI >50 use 22-25 kcal/kg of ideal bodyweight.
Generally use normal protein goals for kidney failure. If on CRRT, however, need to account for loss of aminos in the membrane, may be ~15-17%.
