Dr Neel Desai provides an Update on Anesthesia for Cesarean Delivery at #OAA23ASM #OBAnes Image
Starting with the mainstays: choice of local anaesthetic and intrathecal morphine. Prilocaine 2% has compared favourably with bupivacaine 0.5%. However, there are caveats: if prilocaine is to be considered for routine #OBAnes it is recommended a CSE be used. ITM does NOT prevent… twitter.com/i/web/status/1… ImageImageImage
The very topical: inadequate neuraxial anaesthesia for cesarean section. See lectures from @hnixon147 and @PervezSultanMD from recent @SOAPHQ annual meeting elsewhere on my timeline - this is a widespread concern. @Jamesocarroll has initiated a large multicentre trial through the… twitter.com/i/web/status/1… ImageImageImage
Excellent guidelines on testing blocks and approaches to inadequate #OBanes in @Anaes_Journal from Dr Felicity Plaat, @SusannaStanford @noolslucas et al. Keystone = multimodal testing. Upper and lower limits should be assessed (lower is more tricky) #OAA23ASM ImageImageImage
Regarding GA for cesarean section: PERIoxygenation. TIVA for cesarean section- do we know enough? Are models we have for TCI applicable in pregnant population? @YavorRM has lots of research questions. Risk factors for #OBAnes difficult intubation similar to non-pregnant… twitter.com/i/web/status/1… ImageImageImage
Carbetocin non-inferior to oxytocin (not necessarily equivalent, not superior), does have advantages but at a price? IV dexamethasone has analgesic benefits- is it safe for all #OBAnes? Is there an optimal NSAID for post cesarean section analgesia? #OAA23ASM ImageImageImageImage
TAP block superior to wound infiltration wrt pain score at rest at 2h, but no other differences (this is not simple subdermal infiltration mind you - @MarcVandeVelde6 has an impressive video not for #SoMe). ESP block for cesarean section - I have some concerns about this in… twitter.com/i/web/status/1… ImageImageImageImage
ESP has been included in PROSPECT guideline for elective cesarean section. Premature? #OBAnes #OAA23ASM Image
Ethnic disparities in #OBAnes care. @SQuashie covered this extensively at #Anaesthesia2023 - her lecture is elsewhere on my timeline. More likely to receive GA, less likely to have a neauraxial for assisted delivery - worrying. The why’s abound, definitely an area for more… twitter.com/i/web/status/1… Image
Conclusions from Dr Neel Desai. Multimodal testing. PERIoxygenation. Single shot LA infiltration? #OBAnes #OAA23ASM Image

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

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

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

Bookends the 1st #OBAnes session, on intrapartum pain at cesarean section… twitter.com/i/web/status/1… Image
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 ImageImageImageImage
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 ImageImageImage

Dr Ning Nan Wang introduces @harshamd5 to open the chronic pain session: Perioperative use of opioid in the context of Opioid Epidemic. #CASAM2023 ImageImageImage
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… ImageImageImage
Opioid use around the time of surgery. Understanding nociception vs pain. Does eliminating opioids during surgery make a difference - no definitive conclusions. #CASAM2023 ImageImageImage
