1/ 🚨New Episode! 🚨

What is an “appropriate” Hgb bump?

Why do we usually say 1g/dL for 1 pRBC?

iTunes: bit.ly/coreimpodcast
Show Notes: bit.ly/3eUgyGw

First, let’s figure out how many grams of hemoglobin are donated?
2/ What is the patient’s PRE-transfusion #intravascular volume?

Usually 6.5% of body weight for women 👩
Usually 7.5% of body weight for men👨
3/ What is the patient’s POST-transfusion intravascular volume?
4/ What rise in hemoglobin can be expected after transfusion?

It's all division here to get the g per dL bump you expect and viola!

It works out nicely for a 13g/dL donor Hgb to a 70Kg male recipient !
5/ While the 1g/dL bump for 1 unit pRBC is a good rule of thumb, there are other factors that can affect hgb response to transfusion!
6/ Let’s apply two different scenarios with different:
(1) amount of g/dL of donor and
(2) body weight of the recipient

Takeaway: 1 unit pRBC can increase hgB response anywhere from 0.6g/dL to ~1.6g/dL!
7/ Thanks for following along, #MedTwitter!

And a huge thank you to our team:

🫀Fatigue
🫀Exercise intolerance
🫀JVD
🫀Pulmonary rales
🫀LE edema
3/ On echo, HFpEF is NOT:
🫀Just diastolic dysfunction

**Diastolic dysfunction CAN be seen in HFpEF 

But, it was not observed on resting echocardiograms of ⅓ of HFpEF patients in the Paragon-HF trial ‼️

2/ Not all AKI in heart failure is cardiorenal syndrome!

In pure cardiorenal, expect a “bland” UA with no:
🥩 Protein
🩸 Blood
🦠 Granular or other cell casts!

**Remember, keep a broad differential for AKI
3/ You suspect volume overload in a patient…what dose of diuretic do you start with?

2.5x their home dose of diuretic (in IV form)!

IV options include:
💉 Furosemide
💉 Bumetanide

**Bumetanide drip at higher doses is associated with myalgias

1/ Time for #12LeadThursday!

What’s the axis and do you notice anything about the precordial leads? Image
2/ What do you see on ECG to identify extreme axis deviation?

Negative deflection in lead I + negative deflection in aVF = extreme axis deviation Image
3/ What about the precordial leads?

Do you notice dominant R waves, S waves, or T-wave inversions? Image

1/ Atrial Fibrillation: #GrayMatters Series

What do you do with that episode of #Afib when sick or post-op in the hospital?

What type of monitoring is best?

2/ When do you start AC for new Afib post-op?

We hope this infographic will be handy for the many times we may be in the gray zone!

From @accpchest guidelines

A few things to consider:
🤔 Patient specific risk
🤔 Blood thinner of choice
🤔 Bleeding risk of the surgery
3/ Credit to the team that worked tirelessly on this!
