First the PRE-debate audience poll - the NO’s have it. Looks like @amit_pawahas an easy job today
@jeffgadsden takes the Pro argument, in what he feels shouldn’t really be a face off. Note: tearing off the nerve stimulator cord is a tad aggressive #RAUK23
@jeffgadsden proposes the 4 pillars of his argument. 1. A means to avoid intraneural needle tip placement. Seems to shoot himself in the foot immediately by pointing out poor sensitivity #RAUK23
Ah, good recovery from @jeffgadsden. It may not be sensitive BUT it’s very specific #RAUK23
Triple monitoring reduced false negatives. With US alone are we 100% sure we’re not too close every time - No. Not much literature to support, but consequences of error are massive. Worth having a belt and braces approach? Probably. #RAUK23
And it’s easy to do - 6 seconds. What an awesome slowmo replay! #RAUK23
2. A way to avoid skewering neighbouring nerves. RAPTIR block illustrates tiger territory - suprascapular nerve. #RAUK23
A solution = stimulation. Note: hand placement to detect a twitch while advancing the needle #RAUK23
Also during Adductor Canal Block that regionalists perform daily - nerve to Vastus Medialis not always visible on US #RAUK23
Sure dissection with saline helps, but stimulation adds efficacy and safety (twitch means stop). Consequences are notable. #RAUK23
3. Help identify nerve when US fails. Not sure how much of USA constitutes the “Biscuit Belt” but we all have obese patients where US does NOT visualize the nerves - stimulation keeps us safe? #RAUK23
4. Help identify correct fascial plane. QLB needs to avoid injection into Psoas Major - otherwise you end up with lumbar plexus block (effective but can’t move leg). If psoas muscle twitches = bad! Know you’re there when QL stops twitching. #RAUK23
Summary of how stimulation helps. Equates to seatbelt vs airbags debate (seatbelts so last season once airbags arrived) - but both = better! #RAUK23
@amit_pawa up for the CON side of the debate. Keeping the patient in sight as the real winner of the debate no matter which way it goes. #RAUK23
Oh dear, a sign of weakness from @amit_pawa - altering the parameters of the debate? Will it hurt him? #RAUK23
Appealing to emotions of the audience - excellent debate strategy from @amit_pawa (I’m sure @RegionalAnaesUK will miss him). But his talk will be serious with no-subliminal messages whatsoever #RAUK23
Does nerve stimulation really separate these bromance partners of @BlockIt_Hot_Pod? @amit_pawa has cried foul on tape - says it was AI. #RAUK23
@amit_pawa focusing the point of the debate - or more specifically where the needle’s point SHOULDN’T be. #RAUK23
Despite advances in regional anesthesia, long term nerve injury remains unchanged. Do we need a belt and braces (or triple check) approach. Ooh early but has @amit_pawa delivered his mic-drop moment quoting @jeffgadsden from the literature? #RAUK23
Illustrating the premise, but is it always reliable? Right @jeffgadsden spoke about 0.2mA, but most use higher values… #RAUK23
A tale of two pigs (no third found @amit_pawa?): NO twitches with INTRANEURAL needles - not very sensitive. Ultrasound DOES detect intraneural injection #RAUK23
Humans now: Parasthesia is old school (even me an #OBAnes agrees) but parasthesia occurs in absence of twitch, may not detect neural contact. PNS did not prevent intraneural injection. Good solid literature argument from @amit_pawa - definitely negates sensitivity #RAUK23
Extra points for the Star Wars reference! This is the Way! Mat the fourth be with you #RAUK23
Addressing the bromance directly - nerve stimulation did not prevent intraneural injection. Still skewering nerves (now I’m hungry) #RAUK23
Does dual guidance prevent harm? Apparently not. Question in my mind is that we know it’s not sensitive, but is that the point? Clearly stimulation is not sensitive enough - but if it’s specific… will @amit_pawa address that? #RAUK23
Do we need to get that close to the nerve that stimulation would be useful? Can stay 1.6mm away from nerve with effect in 95%. If Yoda says it, I believe it - but literature added as well #RAUK23
Ah @jeffgadsden quoted again (@ajrmacfarlane this is Kylo Ren from sequel trilogy, Darth Vader’s grandchild IYKYK) Summary of the argument so far - specificity missing? #RAUK23
Ripping off the stimulator cord does like quite satisfying though #RAUK23
@jeffgadsden not only wins debate, but successfully overturns the pre-debate poll! Well done! But as @amit_pawa pointed out, the patient is the real winner! (And @amit_pawa may have been prejudiced by a few Trekkies in the audience) #RAUK23

@SQuashie presents an update on anesthesia for operative delivery. Declarations. Methodology and themes. #OAA24ASM #OBAnes
Gastric USS. Oral rehydration has benefits over NPO wrt vasopressor use. #siptilsend safe, noting some patients have increased gastric volumes irrespective of starvation status. #OAA24ASM #OBAnes
@SQuashie continues at a rapid pace. To DPE or not to DPE remains a question - 16min vs 19 min, is that 3 min clinically relevant? Esketamine for supplemental analgesia - >95% had psych effects, read @rjharrison79 editorial. #OAA24ASM #OBAnes
@Jamesocarroll presents an Update on Labour and Delivery. Disclosures #OAA24ASM #OBAnes
How the lecture was put together. Screening. Themes. How to interpret the slides. Very Ostheimer-esque @Jamesocarroll #OAA24ASM #OBAnes
@Jamesocarroll Clinical practice theme: intrathecal catheters & ADP. Intrathecal catheters: No decrease in PDPH, but reduction in EBP. 10mL intrathecal saline decreased PDPH & need for EBP. Of note, the percentage of epidurals requiring multiple attempts. #OAA24ASM #OBAnes
8am-ish in Denver and time for a much anticipated session: PDPH beyond the guidelines. Moderated by Dr Lisa Leffert, featuring @Ropivacaine, @euklaas, @sharonOzynger and @WouterSchievink at #SOAPAM2024 #OBAnes
(HT: @Ropivacaine, bless his heart, he knows I hate missing out)
Hot off the Press? August 2023! @JAMANetworkOpen with quite an illustrious team including @Ropivacaine @robin_russell1 @KalagaraHari @LimGrapes @claralexlobo @noolslucas @NarouzeMD (please tag others if you have their handles?) #SOAPAM2024 #OBAnes
Introduction, Methods and the 10 questions. #SOAPAM2024 #OBAnes
Next up at #CASAM2023 - fittingly keeping the most important academic session to last: #OBAnes @ValZaph moderating the Maternal Experience and Outcomes: Improving the care we provide. @DrWesleyEdwards
Dr Christina Lamontagne kicks off the session with: Use of Dexmedetomidine in improving maternal experience and outcomes. Nothing to disclose. Then an important disclosure: All indications discussed are OFF LABEL in Canada. Objectives. #OBAnes#CASAM2023
Why does Dr Lamontagne use a lot of dexmedetomidine (not only in #OBAnes mind)? Clinical pharmacology of dexmedetomidine (1): highly selective alpha-2 agonist; sedation WITHOUT amnesia at locus coeruleus. #CASAM2023
Dr Ning Nan Wang introduces @harshamd5 to open the chronic pain session: Perioperative use of opioid in the context of Opioid Epidemic. #CASAM2023
The opioid crisis isn’t new - China probably remembers the Opium wars that helped establish a British foothold on the continent. Opioids and OUR crisis. Is what we fear the real crisis? Are opioid-related deaths due to surgical prescriptions? No, mostly due to street fentanyl.… twitter.com/i/web/status/1…
Opioid use around the time of surgery. Understanding nociception vs pain. Does eliminating opioids during surgery make a difference - no definitive conclusions. #CASAM2023
