๐Ÿ‘‡๐Ÿ‘‡ Live Thread for the great topics of #C19marathon, 22/05/2021 - #COVID #ICU @ESICM ๐Ÿ‘‰๐Ÿ‘‰ Watch the conference live here: esicm.org/events/lives-cโ€ฆ

Today, we'll be using the hashtag: #livesc19 for all content.

#livesc19 We'll kick off by looking at what went well and what we can do better together, accompanied by a global update on #COVID19. A focus on the science used to fight the pandemic and the successes/difficulties we had throughout the world. @DrMCecconi @msh_manu @strachanjamie

Follow @avkwong @iceman_ex @strachanjamie @TrishMcCready @FOAMecmo for the SoMe content throughout the day :-) #livesc19 #FOAMed #FOAMcc #COVID19

facebook.com/intensiveconneโ€ฆ is an alternative Live Video link for anyone getting involved with #livesc19 today :-) #FOAMed #FOAMcc

130,000 healthcare professionals united within @ESICM in a joint approach to #COVID19 across the world. We have enormous challenges ahead. We are better together. #livesc19

"A ventilator is not an ICU bed - an ICU bed is a team of healthcare professionals working together." @DrMCecconi #livesc19

Non-ICU front-line workers can avail of training with the "C19 Space Programme" #FOAMed #FOAMcc esicm.org/covid-19-skillโ€ฆ #livesc19

@WHO expert Dr Ann Lindstrand works in immunisation and updates us on #COVID19 Over 163 million cases worldwide and >3.3 Million Deaths austerely frames the topic... #FOAMed #FOAMcc #livesc19

"The science has been extraordinary" - many very safe vaccines rolled out in their billions.... #livesc19 - we have a lot of work yet to do... #COVID19 - the key is collaboration. The green map below needs to be a homogenous colour! @DrMCecconi

Huge distribution of vaccines across the world #COVID19 but 10 countries have administered 76% of all doses. "We are worried about the vaccine race" - of individual countries - it needs to be a global approach #livesc19

95% of member states (of @WHO) have commenced vaccination programmes - but the inequity is CLEAR - 16.5% of doses administered in countries that represent almost HALF of the world's population #livesc19 #COVID19

20% vaccine coverage in a country is a critical number - only Bhutan/Mongolia (of LMIC/LIC's) have achieved this #livesc19

Vaccine Rollout Challenges in #COVID19 #livesc19 - funding amongst serious problems.... This is COMPLEX work with multiple vaccines. Majority of countries use multiple vaccine types - this adds to coaching, admin and logistical requirements.

'At risk' age shift seen now, in Germany for example. Younger people more at risk of serious #COVID19 complications. Disruption of vaccine rollout is serious. #livesc19

Fascinating insights - general vaccine programmes (measles etc) have slowed down or been POSTPONED due to #COVID19 vaccine prioritisation:

Let's go back to 2019... with @msh_manu - WE WERE NOT READY! #livesc19 #COVID19

80-90% of research can be considered 'wasteful'.... this is seriously problematic. "Random drugs to small numbers of people outside RCTs etc...." @msh_manu #livesc19

January to January 2019-2020 comparison... #livesc19 #COVID19

Lockdowns changed the trajectory of the pandemic. The UK learned from Italian lessons. #livesc19 #covid19

We know that there is a clear COVID infective pathway in the body now - it's cytotoxic to the cell and *can* lead to immune dysregulation: @msh_manu #livesc19

There are more asymptomatic and mild infections versus hospital admissions/serious disease. We know the general trajectory now. #livesc19 #covid19

It's a MULTI-SYSTEM disease... this isn't just a "ventilator disease" @msh_manu #livesc19 #covid19

We are trying to explore #COVID19 in the context of insufficient knowledge. We needed to embrace uncertainty and study it. We need to focus on things that assist BEDSIDE management. #livesc19

There is a serious shift in study numbers and participants - representing tremendous effort from all involved #livesc19 #covid19 @msh_manu

We have learned: NO to ivermectin, hydroxychloroquine, antivirals and ?remdesevir. Steroids in certain circumstances. #covid19 #livesc19 @ESICM @DrMCecconi @msh_manu

Clinical sequelae of #covid19 common to sepsis and critical illness. A HUGE opportunity for shared learning here. @msh_manu #livesc19 #foamed #foamcc

3200 submissions (75% increase) to @yourICM journal - we have managed to maintain academic integrity despite this! #covid19 #foamed #foamcc

Prof Nicole Juffermans now chairs our panel on Respiratory Failure! #livesc19

And we're off! #livesc19 #foamed #foamcc

The traditional view of ARDS: #livesc19

But we need to look at the mechanisms of dysregulation and injury in #COVID19: severe endothelial injury, vascular thrombosis and *new vessel growth* - these are multitudes greater than ARDS #livesc19

Severe lung perfusion abnormalities in #COVID19 predict (to a degree) an increased risk of ICU and IMV. #livesc19 #foamed #foamcc

The lungs of sick H1N1 patients are heavier than #COVID19 lungs #livesc19

Thus, preserved compliance is more prevalent in #COVID19 #livesc19

PEEP doesn't come without a cost - we need to consider the atelectotrauma and volutrauma etc #livesc19

Look at the bottom here - the transition of #COVID19 patients is very different vs standard ARDS #livesc19

A traditional approach to escalating interventions in ARDS: #livesc19

What is the rationale of HFNO in #COVID19? #livesc19

Can we use ROX (pulse ox/FiO2 ratio) to dictate therapies in #COVID19? #livesc19

Helmet-delivered NIV was associated with less intubations in #COVID19 #livesc19

Dr Piquilloud kicks off a session on COVID ventilation - she highlights what our considerations should be: #livesc19 #foamed #foamcc

ARDS IS HETEROGENEOUS! Individualisation of settings is important. Focal v non-focal aspects (many misclassified) on CT/CXR can dictate treatments/strategies? #covid19 #livesc19

#COVID19 ARDS is a **very** heterogeneous syndrome. PEEP is very individual. #livesc19

Aforementioned Type L patients might suit PEEP 8-10cmH20 and Type H might suit higher PEEPs? This still needs tested prospectively. #foamed #foamcc #livesc19

How were patients ventilated in 2020 (with #COVID19?) - 14075 patients over 26 studies:

What about ARDS rescue therapies in #COVID19? "Proning" appears to work and is safe. It improves oxygenation. #livesc19

In real life - proning was used a lot, followed by pulmonary vasodilators and then ECMO in a smaller amount... #livesc19 #foamcc #foamed

Some serious discussions around CPAP/NIV in deteriorating #COVID19 patients! Best practice is still suggested to perform such NIV in an HDU/ICU setting - but resources may dictate otherwise... *discuss!* #LIVESC19

A potential blindspot is that a lot of our very sick are cared for (expertly) outside an ICU setting, utilising CPAP/NIV - and this is often outside the data capture of ICM trials (and ICNARC in the UK) that frame this into useful information. @iceman_ex @avkwong @Wilkinsonjonny

The amazing @bhwords deciphers the tricky concepts of thrombosis in #COVID19 patients. #LIVESC19

@susannaprice "no kneejerk reactions without the evidence" - WRT IVIG, aspirin etc in #COVID19 patients.

How does the heart respond to #COVID19?

Loss of radial function and VA uncoupling seen in the right heart in #COVID19 - this is unlike the 'ARDS right heart' @susannaprice

Fascinating - 141 countries, 6 countries, 80% reported a reduction of STEMI presentations during pandemic - and many presenting after the optimal treatment window. Reasons: degree of lockdown, levels of COVID admitted to hospital, restructure of cardiology units. #livesc19

Are the components of #COVID19 within ICU that much different from more traditional critical illnesses? @ElieAzoulay5 #livesc19

Dr. Herridge delves into the post-COVID19 conditions. #LIVESC19

High ICU mortality (55%) in Brazil and high admissions (39%) - "COVID is a different disease in different healthcare and social constructs" #livesc19

In intubated patients post-COVID, they have (obviously - but some surprising) different outcomes versus non-intubated patients.... #livesc19 MANY people are re-hospitalised. "Return to normal" is challenging +++ (medical, psychological, financial)

This study made me think about how we deal with things that matter to the survivor patients - from hair loss to sleep difficulties. #livesc19

ENORMOUS impacts on delirium, and one might hypothesise, long-term cognitive function. The battle within polypharmacy is very real.

*Unknown* long term trajectories in COVID19 - a multi-system and complex problem. #livesc19 - can we learn lessons from our ARDS patients? Yes.

@JanJDeWaele prep for our antimicrobials in #COVID19 session!

"It is very difficult to distinguish covid pneumonia from other pneumonia" We need excellent antimicrobial stewardship. #LIVESC19 Two "ifs and whens" to start abx -->

Co-infection with bacteria at ICU admission stage is VERY difficult to ascertain. But... 28% (limited data) COVID patients had co-existing infection. Look at the % of patients on broad spectrum abx with COVID-19! #livesc19 90% of ICU patients and 72% of hospital pts.

A ook at ICU acquired infections #livesc19

Final thoughts of abx use are common throughout ICU presentations - but some data considerations here - high risk of VA-LRTI after 1 week ICU stay as well as low rate of co-infections at ICU admission. #LIVESC19

Prof. Garyphalia Poulakou is taking us through living reviews and metanalysis of bacterial infections in COVID-19 patients. She highlights the overlapping clinical features of COVID-19 and bacterial pneumonia.

Great insights into how we can predict superinfections in #COVID19 patients. We can all reflect on these issues in ICU #livesc19 #foamed #foamcc

How to investigate the COVID-19 patient with suspected co-infection --> #livesc19
