Wow, this is crazy! It’s amazing to see how much love my Avengers as pressors series has been getting 😁 The following is a thread with all 7 pressors for easy access!

Thanks for the idea @ETSshow!

I listen to ~90 #Podcasts on a (semi) regular basis. Let me give you a rundown of ALL of them and why you should listen to some amazing #FOAMed, especially for all the new #EmergencyMedicine interns. #FOAMed #MedEd #medtwitter
First of all, you need a good podcast app. I absolutely love Downcast. Great app, gives you more control over playback, downloading, and allows you to categorize your podcasts into playlists (picture 2). This is where you get to customize your #FOAMed experience! #medtwitter
In no particular order,

- Anesthesia and Critical Care Reviews and Commentary (ACCRAC). Great insight into Crit Care from an anesthesia perspective. Coming from EM, this is great to listen to- much different from my day-to-day! #FOAMed #FOAMcc #CriticalCare

1/ Why is lactate elevated in sepsis or septic shock?

@dolan_russell & I explore this common #ICU pimp question via #tweetorial.

We're taught that ↓O2 revs up anaerobic metabolism causing ↑ lactate. But wait, there's more...

#medtwitter #FOAMed #meded #FOAMcc #criticalcare
2/ In homeostasis, lactate is continually produced and metabolized; serum concentration is at steady state.

Which of the following organs is responsible for the majority lactate consumption and metabolism?
3/ The liver is responsible for ~70% of lactate metabolism.

Patients with hepatic dysfunction can have ↑ lactate 2/2 ↓ clearance or ↑ production. Also, cirrhotics are more prone to hyperlactatemia in setting of sepsis.

Diving deeper, how does the liver metabolize lactate?

The ANDROMEDA- SHOCK Randomised Clinical Trial
Thoughts by @z_cepillo
jamanetwork.com/journals/jama/…
Multicentre (28) open label RCT to determine if peripheral perfusion targeted resuscitation during early septic shock in adults is more effective than a lactate-targeted resuscitation for reducing mortality.
Inclusion criteria: adult patients with septic shock (infection, lactate >2, vasopressors to maintain MAP >65mmHg after IV fluid of 20ml/kg over 60 mins.

1️⃣ Shunt
2️⃣ V/Q mismatch
3️⃣ Low FiO2/low O2 tension
4️⃣ Alveolar hypoventilation
5️⃣ Diffusion limitation
6️⃣ Venous admixture
#CriticalCare
1️⃣Shunt - can be intra or extrapulmonary. No V, only Q. Does not respond to O2 - shunt fraction not exposed to o2. Inflamm alveolar dz (eg PNA) can p/w shunt (imp. vasoconstr.) Think abt PFO w R➡️L shunt in PE, ARDS (elevation in R sided pressures), check bubble study. Aa grad ⬆️
2️⃣V/Q mismatch. More Q than V but regions with low V not entirely excluded from gas exchange. Can improve w increasing FiO2. Probably 75-90% of hypoxemia cases. Wide Aa gradient.
