In this new episode of the ACE podcast, editors Christopher Lace, M.D., M.B.A., Stacy Jones, M.D., FASA, Joel Johnson, M.D., Ph.D., and Vidya T. Raman, M.D., FASA, discuss some of their favorite items in the 16B issue launching in October 2019, including a behind-the-scenes look at where they get their ideas for ACE questions. Some topics discussed include increasing rates of malignantly adherent placentas, how anemia can mask hypoxemia, and the use of spinal anesthesia in infants. The editors also discuss some of the “gratuitous information” in the 16B issue and why they consider it beneficial for ACE learners.
