First comes @JAMyburgh with #SuDDICU looking at selective decontamination (SDD) of the digestive tract on hospital mortality

(To know- Aim of SDD is to prevent VAP caused by pathogenic gram negatives organisms and overgrown of fungus from upper GI tract)
The paper is open access here…

And summarised in graphic by @JAMA_current. Image

🧠 Heading here this morning for joint @ERC_resus session ‘How do I predict neurological outcome after cardiac arrest” at #LIVES2022

This is a core part of my day to day and frequent conversation I have with the junior team so interested to listen …
So far the audience have been asked four times to move closer to the front. Nobody moves.
The first q is ‘how do you do it’.

Sandroni says Neuron specific enolase (NSE) for 3 days, clinical exam from day 3, EEG starting early…used later, CT is repeated in patients with prolonged unconsciousness and MRI in those that aren’t waking up..

They have protocol on unit

It’s 16:40 - I’ve come to palliative care session

I *think* (but cannot be sure) that it won’t mention biomarkers

Impressive turnout for such late session. It’s actually nearly full!

#LIVES2022 ImageImage
First speaker Hartog said she’s surprised by the turnout ☺️

She comments that the WHO definition of palliative care (PC) doesn’t mention death

She directs us to concept that it accompanies curative care - then takes overtakes it - and eventually, no even continues after death Image
She points to this paper and graphic.

(You should know now the room is so full that people are standing, which is tiring imagine- but good to see for such an important topic)… Image

Carolyn Calfee Clinical and Biological phenotypes of ARDS
- what do they have in common?

ARDS : subgrouping since the begining
- sepsis vs. non sepsis
- hyper vs. hypoinflamm
- reactive vs uninflamed
#ventilation #ards #phenotypes #LIVES2022
Are clinical phenotypes biologically distinct?
looking at Trauma vs. Non trauma

ICAM-1 , SP-D, vWF, sTNFr-1 are different.
What about in "Direct" vs. "indirect"
or "Diffuse" vs "focal" -- sRAGE comes up again.

"Do we Need a biological definition of ARDS"

- Berlin definition has NO Diffuse alveolar damage .
- the Berlin defn does not capture well
Frohlich - different definitions specificity of 0.63, 0.42, 0.31 even!
#ventilation #ards #LIVES2022…
The BJA article by Frohlich.
Fibrosis only starts after 7 days
Thille article :…
In essence, different disease processes are happening to the lung at different times in the "ARDS"

ARDS - new definition or phenotypes by @GicoBellani refreshing with Kigali definition of ARDS - useful not just low resource but during pandemic in supposedly high income settings and only draw back is no PEEp requirement #ards #ventilation #LIVES2022 @ESICM
@GicoBellani @ESICM Resolved versus confirmed ARDS
- prospectively applying Berlin definition did work but if ya wait 24 hrs and re-measure P/F ratio, you end up stratifying much better.
- Better separation of groups
#ventilation #LIVES2022
@GicoBellani @ESICM Whichever definition - american european consensus or Berlin or Kigali -- all goes back to Ashbaugh original paper in 1967…

Why are we so confused when it comes to ARDS definition ?

🧠 Optimising Brian perfusion after resuscitation.

This is another debate (read chat, more than debate)

So I’ll try to keep up… Image
It opens by saying we know that 2/3 of unconscious patients in ITU post cardiac arrest die

And most of them die from brain injury

(I’ll use HIE to say hypoxic ischaemic encephalopathy from now)

❓Do we need to improve perfusion to the brain and can it help anyway❓
HIE brains have inflammation, reorganisation and things which alter interaction with systemic circulation.

Robba is surprised that we don’t seem to categorise post arrest brains as other brain injuries and so treat them with the same systematic approach

NEXT Speaker : VA ecmo for which patients?

Severe cardiogenic shock has different phenotypes
1. medical cardiogenic shock(AMI, end stage dilated CM, myocarditis, septic shock)
2. Post cardiotomy refractory CS (post CABG)
@ESICM #ecmo #resuscitation #ALS
@ESICM 2022 what do the guidelines say
- ESC recommends short term MCS should be considred in cardiogenic shock.
IABP may be considered but not routinely recommended in post MI

what about in refractory cardiac arrest?
ERC - ESICM guidelines 2021
- timing of CAG if no evidence ofr ST segment evaluation.

which means we will end up treating a lot of patients with stent and anticoagulation
TOMAHAWK trial : delayed or early invasive angiography -- no effec.

- immediate catheterisation for non ST elevationrr

Updates on Advanced life supprot by Theresa OLASVEENGEN

Vasopressors and Drugs : recent trial outcomes.
@ESICM #als #resuscitation
@ESICM 2020 ILCOR consensus : strong recommendation to use "ADRENALINE" in cardiac arrest, if you dont have it "LIDOCAINE".

Adrenaline to placebo comparison is mainly 1 older trial with latest PARAMEDIC 2
@ESICM PARAMEDIC 2 - big study
8007 pts, adrenaline 4000, placebo 3999
- a lot of discussion post trial
- need a nuanced interpretation.
- 19 "more good" survivors and 5 "more bad" survivors in adrenaline arm.…

🫁 🧬 ARDS in Sepsis - Are biomarkers helpful? #LIVES2022

(The answer for me is - minimally…I rarely have access to them at the beside 🛌 but I presume the answer from JM Constantin has meat to it, so I’m here to listen)
We start here by asking is ARDS due to sepsis the same as that due to peritonitis or pneumonia?

And he has now changed the title to Are biomarkers helpful in ARDS?
Q1 Do we need them for diagnosis?

No- The Berlin criteria does not need them

Are biomarkers helpful? #LIVES2022

(That’s the question)
Jokes, it isn’t

“Are biomarkers helpful in characterising inflammation V infection?”
The goal is to prevent both under AND over treatment of infection.

As clinicians we have bias
- Tend towards ‘action’
- Over estimate risk of infection
- Over estimate/misattribute improvement (outcome bias)

NEXT : @AriErcole
Association is not necessarily a causation
RCTs are thought of as "gold standard" for a good reason.
"Randomisation" eliminates influences of confounders.
- allows "causality" inference.
@AriErcole RCTs require relatively little prior knowledge.
we try to "by having a inclusion criteria"
🧐 we can only control what we know

RCTs have limitations - dont really imply causality absolutely.

One of the useful things about a conference in Europe is the opportunity to understand a breath of socio-cultural perspectives (it’s almost like we’re better together 💁🏻‍♀️🇪🇺)

Anyway, looking forward to this - let’s go
This is a joint session from ethics and metabolism & nutrition section. They start with Arabi who highlights the variability - he’s trained in US, works in Saudia Arabia and has relationship with Australia

He starts by pointing to this paper
He highlights that there is more agreement for withholding than withdrawing nutrition and that attitude are surprisingly consistent across this large part of the world

He then says that artificial nutrition in Saudia Arabia is more likely to be considered a basic part of care

NEXT Adaptive and Platform trial designs by @Lennie333 #datascience #ai #ml #icudata
#LIVES2022 #ventilation
we assume "large effect sizes" in ICU trials
@Lennie333 @ESICM this is because otherwise we will need large "n" and long time for trials.

e.g., anti-hypertensives - you dont want to test one drug at one dose. you want to test a range of doses and a range of duration.

third-thing : we struggle to find a end-point especially in critical care
@Lennie333 @ESICM huge effort doing RCT but we use "mortality" yes/no as a very binary endpoint. For patient, length of stay, quality of life after d/c important end points beyond survival.

in RCT, we cant learn whilst the trials are still running. in classic RCT.

NEXT Inventory and Comparison of ICU datasets by Christopher SAUER

"Why talk on differences in ICU databases?"
Ans: becuase data is "CORE"
@ESICM #ml #ai #databases #datascience #LIVES2022
@ESICM Merit of publicly available ICU databases
- no randomzined evidence exists for most clinical situations
-data and pt level insights incredibly useful.
-local epidemiology and treatment difers
-real world data sets help deliver optimal treatment policies.

Day 2. Starting on pitfalls in leveraging EHR by Stephanie HYLAND @ESICM #criticalcare #ehr #datascience #ai #LIVES2022
This problem is mainly for ML engineers who may not have talked to domain expert or clinicians / end users.
Pitfall 1 : sampling bias
"whos included in the analysis"
"who in your EHR"?
- e.g., - COVID prediction dataset where missing all blood tests were removed, but this missingess has a meaning. Thus not generalisable.
e.g., yesterday I mentioned about females < 6% of sample popn

Next I’m here for this @ESICM #LIVES2022 chat on ‘diversity’ with amongst others @iceman_ex

My first thought is that this should be in a main theatre
The first question is ‘what is’ diversity

@ElieAzoulay5 says it is ‘us…all of us”

(My own thought on that is the sense of ‘us’ is sometimes the issue but I get the intention)

Ellie says there’s a generation gap - need to understand elements of language that we don’t share
(I agree with that we can’t be afraid to learn form each other)

🫁 Over the past years we have started using NIV more and more for respiratory fairly …practice changed under pressure

But now we’ve taken a breath

When do we use NIV and more importantly …when do we move on?

Follow along for debate #LIVES2022
Bellani says that any T1RF normally warrants a trial of helmet free flowing CPAP to see if they improve by monitoring with RR and paO2

Jaber says no, just get the FiO2 to >92% and then get them to ICU and see what you need…NIV..HiFlo etc
So now what if the patient is on 30L/min and SaO2 not achieving outcomes….

Roca says to asks if the situation is flow dependent (eg work of breathing) then he would first try actual HiFlo (60L/min)

And they ask should we ask patient?

Roca says yes, even considering loss of
