Super easy explain of physiologic Hepatic Pulsed Wave Doppler waveform.

#doppler #radiology #pocus #vexus #hemodinamics #butterflyiq @ButterflyNetInc @hepocus
After appropriate technique to get PWD of suprahepatic Veins.
Look for the 4 classic waves of the tetraphasic spectrum of the hepatic veins (a,S,v,D).

Most of the flow in the hepatic veins is hepatofugal (towards heart).

ICU stories (a brief one): One hour before the end of the am shift, u walk around in the ICU to make sure thinks look OK before u type your sign-out note. You spot the resp therapist & the nurse bagging the pt in Rm 306. From the hallway, u see the monitor: HR 160, RR/45, Sat 70%
This is a 30 yo pt w hx of a catastrophic brain bleed, s/p trach & PEG, admitted 2 wks ago w MDR Klebsiella UTI. Doing well, on trach mask 28%, until the episode of acute/unexpected desaturation
When u examine the pt, s/he is in extremis (accessory muscle use-tachycardic-tachypneic-diaphoretic). BP: 105/55. You grab the stethoscope that the resp therapist wears around his neck & you hear breath sounds in both sides (pt is skinny...)

Young ♀️ w CKD on HD, seen in Cardiorenal clinic

Pt had torrential tricuspid regurgitation due to CVC induced leaflet perforation ➡️ She underwent tricuspid valve replacement surgery 🫀🔪

However, 1 month after discharge she is still using a wheelchair 🤔

#POCUS above shows plethroic, non-collapsible IVC and Hepatic Veins

Did surgery work?

Is there residual tricuspid regurgitation?

#Echofist (PLAx RV view + A4ch) color Doppler lets us see there is no or minimal TR

Prosthetic valve seems to be working

But there is still venous congestion. In fact congestion is significant, take a look at portal vein Doppler 👇

Pulsatility Fraction = 40%, this means there is significant venous congestion. Why?

Is this just volume overload? Should we probe a lower dry weight?

ICU stories: 70 yo pt without medical hx but tobacco use (2 ppd x 40 y) was admitted w shortness of breath a wk ago. CXR/chest CT without PE/infiltrate. Was in afib/RVR on admission; placed on heparin & dilt/b-blocker (w some hypotension). Remained dyspneic, at times restless,
“requiring” multiple sedatives, & eventually was brought to the ICU. Intubated for "resp distress" & mental status changes. "Formal" echo, the day of ICU transfer, showed “LVEF 20% w global LV dysfunction”. On the vent 50% - peep 10. BP 110-130/60-70. Lactate < 2.0
Cards follow for "well compensated heart failure". A look w POCUS upon ICU admission:

Entendiendo la Congestión en insuficiencia cardíaca

Taponamiento renal = más allá del entendimiento del síndrome CARDIORRENAL

Incremento de la presión venosa renal

Compresión de la vasculatura renal y de los tubulos renales
Caída de la filtración por aumento de la presión en la cápsula de Bowman
Incremento de la presión intraabdominal

Ambulatory Hemodialysis Unit Rounds:

Called to see a patient with hypotension: BP 76/40,🧠 OK, CRT 5 seconds

1st step ➡️🛑Ultrafiltration + 300 ml bolus. BP 90/60

Pt is a middle aged ♂️ w ESRD and T2DM

1/9 🧵
Now 3 kg above Dry Weight.

UF Volume so far: Only 600 ml

🔎📁 Previos HD sessions with no hypotensive episodes

1 week with URI symptoms, 2 days with dyspnea on exertion

On exam: No leg edema, Clear 🫁, JVP hard to assess (hx of multiple CVCs and central vein stenosis)


Pericardial Effusion, Normal LV function, looks like there is some RV colapse

Plethoric IVC, Portal Pulsatility 39%.

A-Pattern on LUS, Small bilateral pleural effusions

🚨⬇️BP + Collapsing RV + Venous Congestion (IVC + Portal Pulsatility) suggests Tamponade!

How do you examine the lower extremity venous system when you look for deep vein thrombosis? What points do you check with the probe? Do you use Doppler? What are the recommended protocols? The Society of Radiologists in Ultrasound recommends a complete duplex ultrasound:
👆 The black rectangles represent the extent of the compression US. The gray rectangles are the sites of Doppler.
2-CUS (2-points compression US) includes compression of the femoral veins 1-2 cm above & below the saphenofemoral junction & the popliteal veins
up to the calf veins
ECUS (extended compression US), includes compression US from the common femoral vein through the popliteal vein up to the calf veins confluence

CCUS (complete compression US), includes compression US from the common femoral vein to the ankle

Reason # 67543 why #pocus is important: sometimes mild symptoms are a sign of impending disaster.

41 year old thin athletic male presented to the hospital with a few weeks of mild shortness of breath with exertion.

BP 170/70, HR 100. CXR with cardiomegaly, tortuous aorta.
Bedside #pocus exam shown below:
Most glaring is the size of the aorta. It is clearly larger than the left atrium. Also notable is the anterior leaflet of the mitral valve isn’t opening much.

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

Teleproctoring - mentoring with @POCUSClub

A very poignant question - with so much online learning/recordings/presentations, do we invest in the TIME and tech for these? Or do we just try to replicate the face-to-face version?

lighting, mics, etc

Your mobile phone probably has a better camera than your intergrated laptop #WINFOCUS22

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
