The Swan-Ganz Catheter 🦢🫀

AKA, the Pulmonary Artery Catheter or PA Catheter.

A thread discussing the basics of our PA Cath:
#MedTwitter #FOAMed #ICU
The PA Cath is a specialized venous catheter that can give us a whole host of values related to cardiac function, hemodynamics, and perfusion. 🧐
This cath is a long balloon tipped cath that enters the venous system. It is passed into the RA, through the tricuspid valve, into the RV, and then finally through the pulmonic valve with the tip resting in the pulmonary artery (PA). 🫀

ICU stories (a boring one…): If you work in a general ICU of a community hospital in United States, one of the common admissions you will get is the unfortunate resident of a nursing home or rehabilitation center that lives there for several decades & at some point becomes
febrile/“altered” & is sent to the ED for “evaluation”. The course is so predictable that we usually consider these admissions “boring”. This is the case of a middle-aged pt w cerebral palsy/mental retardation/seizures (on valproic)/PEG-chronic Foley in place who was sent to
the ED for fever+hypotension+tachycadia. Labs: WBC 15k, lactate 4.0. UA -as usually- suggestive of UTI (WBC>50, +bacteria, +nitrite, +esterase). CXR “clear” & pt w sat 99% on room air. Received ivf, Abx (pip/tazo + vanco) but due to persistent ⬇️BP, norepinephrine gtt was ordered

AF-atrial fibrillation
ST-sinus tachycardia
VT-ventricular tachycardia
AFL/AT-atrial flutter/ atrial tachycardia
This is the ff-up ECG. This is not SR. The 🔑 to rhythm dx is in the PRI (long lead). You need a caliper to 👀 the PR difference. If you have 🦅👀 the extra P can be 👀. So, the ECG case can be explained with 1 reason.

It's December, already. The time of the year when I am trying to spend every last cent of the annual allowance given to us for continuing medical education (CME) by our employer. In essence, this is money that we have worked for and, since it won't carry over to next year, I hate
leaving it on the table. The problem is that if you buy a conference or a study course now, you have to watch everything - and submit proof of attendance/completion - before the end of the year. So, it's a very busy month dedicated to studying/reviewing educational material!
For example, I just finished watching the last one of the 93 lectures from The Hospitalist & Resuscitationist 2022 conference #HR2022. If you are an intensivist/internist/family medicine/EM physician, I have no doubt that u will find several pearls to bring back to your practice

1/Asking “How old are you” can be dicey—both in real life & on MRI! Do you know how to tell the age of blood on MRI?

Here’s a #tweetorial on how to date blood on MRI
#medtwitter #neurorad #radtwitter #RSNA2022 #RSNA22 #radres #neurosurgery #neurology #meded #neurotwitter #FOAMed Image
2/If you ask someone how to date blood on MRI, they’ll spit out a crazy mnemonic about babies that tells you what signal blood should be on T1 & T2 imaging by age

But mnemonics are crutch—they help you memorize, but not understand. If you understand, you don’t need to memorize Image
3/If you look at the mnemonic, you will notice one thing—the T1 signal is all you need to tell if blood is acute, subacute or chronic

T2 signal will tell if it is early or late in each of those time periods—but that type of detail isn’t needed in real life. So let’s look at T1 Image

1) I am presently working on curating the best free resources for medical professionals.

I will focus on the medical subspecialties.

I will also post some of my own work.
2) Why am I doing this?

Because FOAMed is the future.

Because we have some amazing work on Twitter and other SM that does not get the visibility it deserves.
3) All creators will be credited.

If by any chance, it is not --> please bring it to my attention.

2/First some anatomy. Palatine tonsils (or faucial to the cool kids) sit in the oropharynx between the two palatine arches: the palatoglossus arch in front and the palatopharyngeus arch in back. These are easily visible on physical exam.
3/These archs are actually just mucosa draped over the palatoglossus and palatopharygeus musculature, like kids drape sheets over themselves to dress up for Halloween.

2/Let’s start at the top. At the vertex is the superior frontal gyrus. This is easy to remember, bc it’s at the top—and being at the top is superior. It’s like the superior king at the top of the vertex.
3/It is also easy to recognize on imaging. It looks like a big thumb pointing straight up out of the brain. I always look for that thumbs up when I am looking for the superior frontal gyrus (SFG)

@girardDev presents on managing the obese parturient at #OAA3dc2022. He sets the bar high for the future of presentations at #SOAPAM2023, #OAA23, #ASM23SYD: a QR code that links to all his references as well as a pdf of his slide deck - perfect for #OBAnes #SoMe & #FOAMed.
The value of PERI-oxygenation in obesity is not to be ignored. All patients will go blue, perioxygenated ones take 52 seconds longer (how long it feels depends on the sats?). We all remember the troop pillow, but do we remember the stool? Ergonomics of intubation #OAA3dc2022
@mbrrace meeting 10 November. Hope to see some live tweets of key messages @SusannaStanford. “We are ALL part of the solution” #OBAnes and obesity is definitely part of the puzzle, preventing it part of the solution. #OAA3dc2022

MAPSE in #IntensiveCare (with examples)🧵#FOAMcc #FOAMed #MedTwitter #Hemodynamic #POCUS #EchoFirst #CriticalCare
Take homes:
1⃣ Redefining "the hyperdynamic heart" with #MAPSE
2⃣ MAPSE is better than EF in the #ICU
3⃣ Linking MAPSE with supply/demand-ischemia
1⃣ Can MAPSE redefine "the hyperdynamic heart?
The term "hyperdynamic LV" - EF > 55% - is misleading. It has no relation to a hyperdyanmic circulation; SV/CO. Someone bleeding to death has a hyperdynamic heart, but the circulation is life-threatening hypodynamic.
MAPSE is cardiac motion, and defining the hyperDYNAMIC heart as good cardiac motion makes perfect sense. Recent geometrical analysis of cardiac pumping shows that MAPSE is the main determinant of SV. Fig from @mugander:

Alcohol withdrawal syndrome: I don’t know if u have a similar experience in other countries (or other places in the States) but I've recently seen a big spike in alcohol abuse-related disorders, especially alcohol withdrawal syndrome (AWS). I'm obviously referring to severe AWS
that eventually will need to come to the ICU (if we have a bed available!). There are many fantastic, well-searched reviews on this topic but it may be hopefully interesting for some if I put “my way” out there & also for me to learn from your experience. Even though the focus
will be on the neuropsychiatric component, I believe it is quite important to highlight other parts of AWS management. To this end, I will use the assessment/plan “per organ” approach which is commonly used when we write progress notes here in US. Here it goes:

1/Hate it when one radiologist called the stenosis mild, the next one said moderate--but it was unchanged?!

Here’s a #tweetorial of a lumbar grading system that’s easy, reproducible & evidence-based

#medtwitter #spine #neurosurgery #radres #neurorad #meded #FOAMed #FOAMrad
2/Lumbar stenosis has always been controversial. In 2012, they tried to survey spine experts to come to a consensus as to what are the most important criteria for canal & foraminal stenosis. And the consensus was…that there was no consensus. So what should you use to call it?
3/Well, you don’t want just gestalt it—that is a recipe for inconsistency & disagreement. But you don’t want to measure everything either—measurements are not only cumbersome, they introduce reader variability & absolute measurements don’t mean the same thing in every patient.

1/One important aspect to stroke care is well... ASPECTS.😂

Here’s a #tweetorial to help you remember this basic #STROKE scoring system

#medtwitter #FOAMed #FOAMrad #medstudenttwitter #medstudent #neurorad #radiology #radres #neurology #Neurosurgery #CT #meded #neurotwitter
2/ASPECTS stands for “Alberta Stroke Program Early CT Score.” It is meant to replace gestalt-ing what percent of the MCA territory is infarcted. Instead, it uses a 10-pt score to semi-quantitate the amount of infarcted tissue in the MCA territory on non-contrast head CT
3/You can think of it as a scorecard for the MCA.

For each region of MCA territory NOT infarcted, the pt gets one point

So the highest score possible is 10, and lowest score possible is 0

☑️HALLOWEEN 2022 @AirwayMxAcademy and @dasairway airway nightmare case🎃You are a critical care doc and decorating your ultimate Halloween party👻underwater cave with a healthy friend. The room is now flooding with water and your friend falls down on the rocks…oops😳1/13 #meded Image
2/13 “Are you okay?”Yes but I have difficulty breathing and it hurts. There is 1 scuba🤿unit, and you see a HFNO device & oxygen cylinder. You know that underwater breathing is possible with HFNO. How much flow is needed to swim 0,5 m below surface & b able 2breath underwater?
3/13 First you check the oxygen tubing which is long enough, than you check the class E oxygen cylinder: 1000 PSI. Save PSI 200. How much time/oxygen do you have at 40 l/min to swim underwater? #halloweenairway #foamed #foamcc #airway

Cystic supratentorial brain tumors in adults, the usual and the unusual. Non-exhaustive list of differential diagnostic considerations. The PA had a nice mural nodule, not shown on this figure. #radres #neurorad #FOAMrad #FOAMed #MedEd #RadEd
impossible to tell which is which on only T1-images with GD. Whenever I see an intra-axial tumor in an adult, I automatically consider GBM and metastases as they are the most frequent brain tumors in adults, so even when the tumor looks strange or atypical, they are a good bet.
Brain abcess and epidermoid cyst are pretty straightforward on diffusion-weighted images as their content is very diffusion restrictive. Brain abscess has a thick enhancing capsule, epidermoidcyst doesn't.
