Episode 122: Key Words Part 1 with Gillian Isaac: Crichothyroid Membrane and Propofol

In this 122nd episode Dr. Gillian Isaac and I launch the first in a series of episodes to give high yield information on ABA key words. The first two we address are the crichothyroid membrane and propofol.

  1. Terrific Podcast! Love the keyword review, and Dr. Isaac is especially skilled not only at teaching key concepts in anesthesia, but test taking strategy as well!

    Innervation of the larynx is incredibly high yield! Know it well.

    Another concept frequently tested is which drugs to dose by total body weight versus lean body weight. Propofol is especially interesting as induction of anesthesia with propofol should be based on lean body weight, however an infusion should be based on total body weight.

  2. Hello,

    I am an SRNA taking my exam in December. I found this episode to be super helpful, so please do more šŸ™‚

    At my facility, etomidate is given to patients needing a pericardial window. What would be the pros and cons of using ketamine or etomidate in this case?

    1. Hi Zula,

      Assuming they are getting a pericardial window for tamponade, you want to maintain their heart rate, contractility and diastolic filling pressure. So you don’t want anything like propofol that will drop those. Etomidate is very hemodynamically stable and should be fine. The only real downside is adrenal suppression which probably isn’t clinically significant with a one time dose. Ketamine tends to cause a catecholamine release and some cardiac depression. Usually the cardiac depressant effect is masked by the catecholamine release and you get some increased HR and BP. Ketamine could be a good choice in tamponade as long as they aren’t already fully catechol released in which case the cardiac depressant effect may win out. I’m interested to hear others’ thoughts but in general I think a relatively low dose of ketamine would be reasonable in these patients.

  3. Great podcast!

    I’m an anesthesia resident at McMaster University and I really hope you guys continue with these types of podcasts as they really are a nice addition. I think having it will be a great resource for learning key topics that examinations frequently target!

  4. 3 years later, I am still listening to your podcast! I am still an SRNA- I graduate in Dec! Last night as I was trying to fall asleep I listened to this podcast. This morning, board prep questions number one was what induction med is best for cardiac tamponade—-KETAMINE! Woohoo- you all are great and always inclusive of all anesthesia providers. I appreciate the quality and dedication to helping us continue our plight for evidenced based best practices. Thank you!!!

  5. Love the keyword review episode concept! I feel that this episode is very high yield and I hope you continue to do more episodes like this.

  6. I’m just about to start my CA-1 year, and I absolutely love podcasts so started listening. I was already loving ACCRAC but making the keywords episodes a regular feature would be perfect for my level of training. Thanks for thinking of us!

  7. One word: brilliant! I’m an SRNA graduating in December. I found this approach to studying highly engaging and as you say, high yield. I appreciate Dr. Gillian Isaac’s resourcefulness for preparing her mentees for board examinations. Please create more key word podcasts.
