ICYMI, public health officials fear community transmission of B.1.1.7 (the "UK variant") is underway in Ontario.

I'll dissect each piece of worrying news from this story.

Fun fact: the standard advice for if a dog, cat, or human bites your hand, is to feed the bite. Push your hand further into their mouth, forcing the jaw open.

Nurses, EMTs, veterinarians, etc are taught to respond this

The advice for a human biting you is to jam your hand or arm deeper into their mouth, and rub the spot under their nose back and forth.

If you attempt to remove your hand, or forearm, the teeth do what they're supposed to and gouge out a chunk.

This vicious wolf attack illustrates proper technique.

So: every EMT and nurse who gets bitten by a human, is trained to jam their hand or forearm deeper into the mouth, feeding the bite so the jaw widens enough to remove the limb

Also, every redneck learns this along with the advice of "never run from an angry dog"

“Should I give them more fluid?”

Extremely common question during AKI referrals from junior docs.

⛔️ Fluid management is tricky, often misunderstood, & can cause huge iatrogenic harm ⛔️

We try to convey important principles in THREAD 👇

#tipsfornewdocs #medtwitter #tweetorial

Currently too often patients with high creatinine are given too much IV fluid, driven by an AKI ➡️ fluid reflex

We’ve seen 7 litres be given in one shift.

Medics & surgeons, juniors & seniors, it seems everyone loves to reach for extra IV fluid (especially if urine output poor)

Why does huge volume IV fluid ‘resuscitation’ consistently occur?

Lots of reasons, including FALSE beliefs:
🛑 IV fluid always “treats AKI”
🛑 Hypotension = hypovolaemia
🛑 Lactate >2 means fluid deficiency
🛑 Septic patients are very hypovolaemic

The rule with IV fluids and AKI is to remember this 5 word phrase:

💥 💥 Aim for euvolaemia, then stop💥 💥

Fluid status is like Goldilocks - hypovolaemia is bad for the kidneys BUT excess volume is also harmful for renal function and will cause other complications too.

It is easy to say “target euvolaemia” - but we agree it is more difficult to do!

Fluid status assessment is certainly made harder by a belief that we must only rely on a snapshot assessment of examination features which are NOT specific / sensitive / reliable to elicit like.…

So now we have a certified Serologic testing of Red Cross US blood donations to identify SARS-CoV-2-reactive antibodies, and that battery of testing shows widespread presence of SARS-CoV-2-reactive antibodies in donations made between December 2019-January 2020

ADHD, a thread (1)
If you have #ADHD & are struggling please know you’re not alone. This week on @Overview, we're talking about living w/ ADHD & Anxiety during the pandemic & many the stigmas & misconceptions that making things worse.

I was diagnosed w/ ADHD when I was 7. And in so many ways it’s been a blessing. I love my energy, the hyper-focus, the calm I feel in chaos, the ability to & feel emotions so intensely. It’s allowed me to to see the world differently be in a constant state of wonder.(2)

But realizing all that has been a long, difficult journey so figured I’d share some of my own struggles as well as the resources from @HowtoADHD because Jessica's channel has been a game-changer for me.(3)

First off, #ADHD Attention Deficit Hyperactivity Disorder is a dumb description. It implies a deficit in attention & always hyper people. ADHD is a spectrum, & what we all have in common isn’t that we can’t pay attention. It’s that we have trouble controlling our attention.(4)

There are amazing analogies out there, like trying to watch 6 TV’s at once when someone else controls the remote. Or like driving a race car on city streets and spinning out whenever you try to turn.
