Dr Lyons standing in front of his slide with the methods, drugs and positions someone might use for Rapid Sequence Induction.

Speaking against TIVA in this afternoon's #WSM2026 debate, Dr Craig Lyons first illustrates the number of ways in which we have also "modified" or allowed variation in practice when it comes to RSI.

There are apparently over 3000 combinations available on this slide alone.

Dr Barley standing in front of the lectern, in front of his title slide "TIVA for RSI".

The final session at today's @assocanaes.bsky.social #WSM2026 is a debate.

"This house believes that TIVA should be used for Rapid Sequence Induction."

Our Hon Sec @chronotrope.bsky.social is speaking on behalf of TIVA.

Dr Barley is delivering a rousing and entertaining talk. He does that!

Dr Williams standing in front of a slide on Amaesthesia as a Brain Stress Test.

If we look at anaesthesia as a "brain stress test" and burst suppression as a marker of getting it wrong, Dr Williams argues that processed EEG should be the norm.

Without it, we aren't seeing the harm we might be causing, especially in frail brains.

@assocanaes.bsky.social #WSM2026

Dr Williams in front of a slide illustrating what burst suppression looks like on the EEG waveform, and on Density Spectral Array.

Burst suppression results from an unnecessary depth of anaesthesia, and correlates with delirium, especially in older patients.

Unless you are deliberately trying to accomplish it (such as such as deep circulatory arrest or in treating raised ICP), you should be trying to avoid it.

#WSM2026

Dr Williams at the lectern, in front of her title slide.

Next up at today's @assocanaes.bsky.social #WSM2026 is SIVA's own Dr Susan Williams, speaking about processed EEG and post-operative neurological outcomes.

Post-operative delirium (POD) is a common complication of anaesthesia, with morbidity and mortality consequences.

Thanks again to everyone who attended #SIVA25 in Liverpool last month.

We had a great time, and we hope you did too.

We would be very grateful for your feedback. All attendees should have received an email afterwards, with a link to do so.

Be honest with us. We want our events to be excellent!

Morning!

Save the date! SIVA Annual Scientific meeting 2026 Sandy Park Way, Exeter, EX2 7NN 26th - 27th November 2026

As we wind up today's excellent content at #SIVA25, planning is already well underway for next year.

We hope to see you all again in Exeter, if not before. You have all been wonderful company!

SIVA wouldn't exist or be successful without your support, folks, and we appreciate it.

Goldilocks principle to processed EEG, showing a typical spectral pattern for processed EEG under anaesthesia.

Really excellent talk in the processed EEG session this afternoon from Dr Joana Berger-Estilita.

The goldilocks zone between too deep and too light "looks" a certain way.

If alpha is dropping out and beta is coming back, one of two things is happening. Neither is good.

#SIVA25

Schedule for the final session of the SIVA ASM 2025.

The final session of #SIVA25 is all about processed EEG and monitoring.

We are finishing strong today!

Keep the questions coming via slido, folks, ahead of the final panel discussion at the end of the session.

Slide of generational differences, from Boomers through to Generation Alpha. We have a range of these folks in the room today.

The first talk of the final session of #SIVA25 is about teaching processed EEG, by Dr Joana Berger-Estilita, who has travelled to us from Bern.

How does a doctor learn a new skill, such as pEEG interpretation?

Well, it depends on a lot of things...

Dr Mark Barley stands in front of the lectern, with a slide summarising the rest of this session's content behind him.

Opening the final session of this year's #SIVA25, focussed around processed EEG, is SIVA Honorary Secretary @chronotrope.bsky.social.

Fantastic content, delivered by international experts. We hope you folks have enjoyed all this as much as we have!

Wing Commander Humphreys at the lectern, in front of her title slide.

The final talk of this #SIVA25 session is delivered by military anaesthetist Wing Commander (Dr) Alice Humphreys, who is also a new SIVA committee member, elected yesterday.

She is speaking about Military TIVA, and TIVA use in low power or no power environments, or after a nuclear blast.

Dr Tasbihgou at the lectern, in front of his summary slide. A lot of excellent advice here.

Next up this morning at #SIVA25 is Dr Seth Tasbihgou, who has travelled to us from Groningen to speak today.

His excellent talk on "TIVA - how not to do it", is focussed around how to avoid some of the more common pitfalls, including standardisation, equipment checking, and monitoring.

Schedule for session 2, day 2 of SIVA's annual scientific meeting 2025.

The second session of day 2 of #SIVA25 has started with some excellent poster presentations, and more safety and error based content.

Make sure to visit our friends in the trade exhibition hall over lunch. These folks are an important part of delivering these conferences.

View over the Liverpool skyline. Two cathedrals and the Radio City tower, with the waterfront in the distance. Blue sky, with a few scattered clouds.

Another lovely day in Liverpool for #SIVA25!

We are quite enjoying this view from the conference venue, with the two cathedrals and the Radio City tower, with the waterfront in the distance.

Professor Kenny, standing in front of a slide of Contad Murray and Michael Jackson to illustrate the risks of oversedation.

Last up in our first session of the day of #SIVA25, on safety and design, we have Professor Kenny giving his second talk of the day.

Patient controlled sedation might allow us to achieve the optimal balance between patient satisfaction, and avoiding the risks of oversedation.

Professor Kenny at the lectern, in front of a slide titled "Diprofusor Design Features".

First up in the main session today at #SIVA25 we have Professor Gavin Kenny, one of the key architects of the Diprifusor TCI system.

It is no exaggeration to say modern TCI and TIVA would not exist without him.

In the first of two talks he is giving today, he tells us how Diprifusor was created.

Timetable for the morning of day 2 of SIVA's Annual Scientific Meeting, 2025.

Morning folks!

We hope that those who attended the dinner last night had a splendid time and have woken up bright and refreshed, ready for today's #SIVA25 content!

Those who have registered for the workshop, please note it starts at 0900.

The first session of talks starts at 0915.

See you soon!

A "PERUSE before you Infuse" poster, resting on top of a stack of pre-packaged bundles of posters, each containing 20 posters and some Blu Tack, for putting them on walls. It is all about incentivising the good, innit?

Ahead of my talk today at #SIVA25, I have packaged up some #PERUSEbeforeYouInfuse posters, for anyone convinced by what I'm saying, who then wants to use the check.

The right things happen more often if you make them easy. Providing posters (and Blu Tack) is very much in the spirit of the talk.

Alice Humphreys, in front of an unidentified fruit tree.

We are delighted to welcome Dr Alice Humphreys, as newly elected member of the SIVA committee.

Alice works in a major trauma centre in the south of England and her interests include neuroanaesthesia, transfer and retrieval.

Welcome!

#SIVA25

Schedule for session 2 of day 1 of the SIVA Annual Scientific Meeting.

Session 2 of Day 1 of #SIVA25 gets cracking.

This session is focussed around the science, and is chaired by the always excellent Professor Tony Absolom.

The first talk is Dr Douglas Eleveld, speaking to us from Groningen about developing the model that shares his name.

Local organiser and session chair Dr Patrick Mullen at the podium, and speakers Dr Orla Lacey, Dr Mark Barley and Dr Paul McConnell.

Sessions 1, Day 1's presenters taking questions from the audience to close the session.

It has been an absolutely fascinating couple of hours.

#SIVA25

The spectrum of delirium, post-operative cognitive dysfunction, and neurocognitive disorders.

Next up at #SIVA25 is Dr Paul McConnell, speaking about defending the brain from the effects of anaesthesia, and the "Safe Brain Initiative".

Post-operative delirium and cognitive dysfunction exist within the spectrum of neurocognitive disorders, which may pre-exist and be worsened by our choices.
