EMCrit 375 - Vasopressors for Early Hemorrhage? We talk about the debate over whether to give vasopressors as part of a balanced resus in early exsanguination. Europeans go one way and North Americans/UK seem to have a different view. Let's discuss...

POCUS in predicting fluid responsiveness by @cardiacACCP
POCUS is more helpful in assessing when not to give fluids than when to give. Insightful!

Weekend #VExUS ology questions for experts @khaycock2 @MDBeni @WBeaubien
1. Why is the S-D relationship preserved despite TR and pulmonary hypertension? (IVC plethoric). Noted prominent A-wave (⬆️RVEDP) but still seems inconsistent with RAP and portal waveform.
2. What's the likely reason for variation in PV pulsatility fraction? (yellow trace is obtained in breath hold). Analogue of Carvallo’s sign?

Ok. Holy smokes this #winfocus2023 talk on central lin micro skills from Ola Borgquist is absolutely superb.

A case everyone needs to know:
A man admitted for CHF exacerbation is normoxic on ambient air. POCUS shows bilateral pleural effusions.
He develops Afib w/ RVR (HR 150s). A med is given. Suddenly he develops hypoxemia (SpO2 84% on NC, 94% on NRB).
What med & what happened?

Why would adenosine, a purine nucleoside, be able to treat supraventricular tachycardias (SVT)?
And why are its effects so short lived (e.g. <2 seconds)?
The answers will change the way you think about this drug.

A patient is admitted to ICU with respiratory failure. The parasternal long axis view is shown. What is the finding?

Another nail in the coffin for empirical bolus based dosing strategies in OHCA.
We can (and do) place invasive monitoring/central access and use titrate dosing to a physiological endpoint using controlled infusions.
But still no mention in any guidelines!
#SPEAR
Your patient is in cardiac arrest. You are giving epinephrine every 3 minutes.
Is that based on any evidence? Not really.
This study in Resuscitation actually measured the epinephrine level every minute after a bolus during cardiac arrest in humans. The half-time was 2.6 minutes. This suggests we may be dose-stacking if we give it every 3 minutes.

Jen Carnell on below the belt POCUS views for cardiac arrest at #MEMC23
Can guide procedures, do pulse check, diagnose DVT as a proxy for PE.
US-guided lines are both faster and with fewer complications.
Peak systolic velocity on Doppler > 20 equates to SBP > 60.

Jag medverkar i kvällens Fråga doktorn och pratar om och visar upp ultraljud. Det är ett så fantastiskt verktyg för läkare och sjuksköterskor och används nu i en stor mängd vårdsituationer. svtplay.se/fraga-doktorn

New ocular #POCUS study in WestJEM confirms what I've always thought
Specificity is better with lower gain, whereas sensitivity improves with higher gain
