ECMO Anticoagulation with Dr. Ali McMichael and Dr. Lisa Settle--Part 1

Dr. Ali McMichael who was previously with us here in Dallas is now an Associate Professor of Pediatrics at the University of Arizona and a pediatric intensivist at Phoenix Children’s Hospital. Her interests include medical education and ECMO anticoagulation. She is the first author of the 2021 ELSO Adult and Pediatric anticoagulation guidelines.

Dr. Lisa Settle is a pediatric critical care fellow at UT Southwestern and Children’s Medical Center in Dallas. Her research interests include anticoagulation management in ECMO, specifically focusing on the utilization of TEG data in the neonatal ECMO population.

After listening to this series, learners should be able to:

Briefly describe neonatal and pediatric developmental hemostasis. Recognize the key differences in anticoagulation of neonates, children and adults.Describe the advantages and disadvantages of commonly used anticoagulants: unfractionated heparin, bivalirudin and argatroban.Describe common laboratory testing for anticoagulation on ECMO and their limitations: ACT, aPTT, anti Xa, VHAsTroubleshoot discrepant anticoagulation laboratory testing. Discuss future research in ECMO and anticoagulation
