@SparklesSpinals presents on Opioids and Pregnancy: Current & Future practice at #SOAPAM2023.

(Thanks to @SparklesSpinals for assisting me with an updated slide deck, and apologies for delay tweeting) Image
On the agenda, intrapartum and postpartum opioid use. 20% parturient fill an opioid script DURING pregnancy, 95% for acute or chronic pain. Opioid use in pregnancy has maternal AND fetal effects. #OBAnes #SOAPAM2023 ImageImageImageImage
What about supervised detox? Relapse rates during pregnancy = HIGH! MAT: medication assisted treatment for parturients with OUD. Methadone & Buprenorphine. Remember tailor opioid treatments with similar Mu affinity. #OBAnes #SOAPAM2023 ImageImageImageImage
US system has unique barriers to MAT. Buprenorphine may be superior to methadone. #OBAnes #SOAPAM2023 ImageImageImage
Moving postpartum on the agenda. Cesarean section is associated with chronic pain: 10% incidence (4% severe, debilitating). @EJA_Journal review by Weibel et al. suggests may be as high as 1 in 5 at 3 months. @IJOA_Journal suggests 26,000 women yearly with persistent opioid use.… twitter.com/i/web/status/1… ImageImageImageImage
@SparklesSpinals points out that the most common source of misused opioids is physician prescription (55%), mainly surgery-related. 10-15unused opioid tablets per person - almost 20 million excess opioid tablets prescribed per year. The 1 & 3 year probabilities of continued… twitter.com/i/web/status/1… Image
@acog suggests that future therapy be individualized. Individualized prescribing - where would we even start?

The development & validation of model to predict opioid use post-cesarean in @greenjrnl 2022 demonstrated opioid use in last 24 hrs as most important factor… twitter.com/i/web/status/1… ImageImageImage
The same authors previously published published a RCT comparing a standard vs individualized oxycodone prescribing (@greenjrni 2018): patients use 60% of script, with analgesia accompanied by 50% reductions in opioid use / leftover drugs.

Importance of education cannot be… twitter.com/i/web/status/1… ImageImage
Further future developments: intentional order sets. No standing PRN opioid orders (if requested, only 6 doses issued), discharge opioid amount based on inpatient use. Maximize multi modal use, have #OBAnes write orders.

Shared decision making as an intervention for parents… twitter.com/i/web/status/1… ImageImage
Legislation. Effects of state law limiting opioid prescription: DECREASED number of patients with > 3 day duration of opioid therapy, median duration of therapy, and average opioid dose. No change in number of patients requiring additional prescription or visiting ED within 7… twitter.com/i/web/status/1… ImageImageImageImage

@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 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

@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

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?

Opioid use around the time of surgery. Understanding nociception vs pain. Does eliminating opioids during surgery make a difference - no definitive conclusions. #CASAM2023 ImageImageImage
