@DrRobbieErskine @ashwani_doc @ESRA_trainees @ASRA_Society @ESRA_Society Adipose and connective tissue present both in and out of nerve. Therefore impossible to discriminate between two using standard ultrasound. Thus, fluid injection pressure does not discriminate. PNS uses different physical mechanism - electricity rather than mechanical sound waves

@ashwani_doc @gamcleod2 @ESRA_trainees @ASRA_Society @ESRA_Society Totally agree @ashwani_doc There a number of good reasons to use both nv stim and US together. (Pressure monitoring probably not)

#WRAPM26 @gamcleod2 talking about innovations in Regional anaesthesia. Who could be better than our Bruce Scott lecturer for @RegionalAnaesUK ASM 26 for this topic who has done a tremendous amount of work over last many years. @ESRA_Society

@Steve_Coppens @KartikBSonawane @AmyPearsonMD @jeffgadsden @ESRA_Society Great to share stage with you Steve Kartik, the slide shows toxic effect of all local anaesthetics on axons in rats. Concentrations should be reduced in patients with vasculitic disease. The session emphasised we have to take time to explain things to patients

@KartikBSonawane @AmyPearsonMD @jeffgadsden @ESRA_Society @gamcleod2 🙏🏻

Local anesthetics are toxic drugs! Graeme MacLeod on the changes seen in the nerves when subperineural local anesthetics are injected. Watch your concentration and choose carefully! #ESRA25

@ashwani_doc @ESRA_Society Thanks Ash Didn't get a chance to chat

Amazing talk by @gamcleod2 on use of augmented reality in #RegionalAnaesthesia #ESRA2025 @ESRA_Society

@casualtysrus @ashwani_doc @RCollEM @ESRA_Society @RegionalAnaesUK Thanks Chris and lovely to meet you. We implemented K. Anders Ericsson’s expert performance approach with deliberate practice and metrics. We know it works in chess and sport but can it make a difference in Medicine

@ashwani_doc @RCollEM @ESRA_Society @gamcleod2 @RegionalAnaesUK It is one of a kind! I’ve never seen such low faculty to delegate ratios and then allowing delegates to choose what blocks they want to learn/ work on. @gamcleod2 you’ve done an absolutely brilliant job in setting up this course. It’s world class.

What a brilliant course. I felt I need to increase my repertoire of blocks for ED patients & master some techniques. Thanks to @ashwani_doc for the recommendation. 5x 1 hour 1:1 Cadaveric needling sessions + 1:2 on models. I didn’t expect this but am not saying I wasn’t trying😝

All those in Regional Anaesthesia wil have heard of @BlockIt_Hot_Pod by @amit_pawa and @jeffgadsden so in homage we are holding our first ‘Block It Till Your Top’ at the Aesculap Academia 8th International Mastery Course with @gamcleod2 adjudicating. uk.aesculap-academy.com/eventdetails/4…

Places available. 1:1 teaching. EDRA accredited 6h needling! 3h scanning. Ideal for EDRA exam. @ESRA_Society @RegionalAnaesUK

@HouthoffKavita @thisgirlblocks @ashwani_doc @PeterMerjavy Of course! Pilots go on the sim every 6 months!

@thisgirlblocks @ashwani_doc @gamcleod2 @PeterMerjavy 100% YES! Are you allowed to do it twice? Can I just come over and hang with you guys? 😂🤣 AMAZING course, dedicated and super friendly staff!

There are still places on this years mastery course in Dundee. In our humble opinion, one of the best courses in the UK. Just ask @HouthoffKavita & @ashwani_doc. It would be lovely to see you all there. Direct link : uk.aesculap-academy.com/eventdetails/4…

Delighted to announce that our Mastery course 14th 15th August is an ESRA affiliate course. EDRA approved and perfect for exam. Places available. Contact g.a.mcleod@dundee.ac.uk @ESRA_Society esraeurope.org/meetings/?meet…

When the players got in at half time, Howe was waiting with a presentation. He showed them the stats of how we drop off physically in the first 15 mins of the 2nd half. He implored them not to do the same. 7 minutes in, this happens. Superb. #NUFC

In nerve roots, intrafascicular injection only occurred if fascicle diameter was more than twice the needle opening length and the entire opening was inside the fascicle. Our latest paper: authors.elsevier.com/c/1kQ0S1dCDur8d @RegionalAnaesUK @ESRA_Society @ASRA_Society

@Ropivacaine @gamcleod2 @glauncel @szerbj @susanne_retter @BJAJournals @aboezaart1 It is not a fair point. The is no evidence supporting erythrocytes over India ink and all literature that states this is self-referenced without evidence or explanation.

@gamcleod2 @Ropivacaine @glauncel @szerbj @susanne_retter @BJAJournals @aboezaart1 This statement regarding the inferiority of India ink and superiority of erythrocytes seems to be repeated without evidence. I see no India ink in the extra-perineural space while throughout sub-perineural space. Clearly the perineurium is impenetrable to India ink. Thoughts?
