It was a privilege to give grand rounds at Advocate Illinois Masonic Medical Center last week in Chicago. I presented “What’s New in #OBAnes “

I enjoyed catching up with friends and making new connections. Thank you for the invitation and the hospitality! #Ostheimer2025

Such an honor to give Grand Rounds at Brigham & Woman’s Hospital (MGB) this past week. Loved reconnecting with my #OBAnes friends and meeting new ones. Thanks for the invitation!

RCT compared first pass success of VL vs DL in neonates:
✅ Video laryngoscopy increases the success rate for first-attempt intubation.
✅ NRP should be updated to include recommendations for VL for intubation

👉 People with twin pregnancy require a 10x higher loading dose of oxytocin than those with singleton pregnancies,
👉 Consider an initial 5 IU bolus at elective CD under neuraxial anesthesia.

🔵 Dose-finding study to determine ED90 of oxytocin infusion to maintain tone after an initial 1 IU oxytocin bolus

🔵 Maintenance infusion of 4.5 units/hour provides continued uterine tone in scheduled CD

Can you perform DPE with 27g?

✅ DPE with a 27g spinal needle had higher incidence of sacral blockade than epidural within an hour after placement.
✅ Time to adequate analgesia did not differ
