Podcast Episode 13: Ketamine and Pharmacology SOMSA 2016 Pre Conference Lab Talk

Effectively taking away pain can be one of the most important things you can do as a medic.  It will enable you to complete a life saving procedure or calm your patient enough to finish the mission.  While the Committee on Tactical Combat Casualty Care has a great recommendation for triple option analgesia, there are times when you need something for a more specific purpose.  Justin and his team of Subject Matter Experts explore different options and strategies for analgesia.  At the end of the episode Justin hosts a shadow box or wargame session with the participants in the audience on the different options for controlling major pain.  This includes actually mixing and administering the chosen agent and discussing the pros and cons of the choice.

This episode was recorded live by a professional camera crew paid for by SOMA in an attempt to share the wealth of knowledge assembled at SOMSA 2016 in Charlotte, NC.  If this is something you would like to see continue or expand to other sessions at future events, please let members of the board at SOMSA know.  Without your input they may figure that the money they spent is not worth it and could use it for something else.


Show Notes 

Justin’s Recommendations:

  • Dial a flow devices allows you to set a drip rate without counting drops
  • Simulated medications will force medics to show that they know how to actually mix and dilute medications instead of mearly talking about it
    • For example: Dilute Ketamine from 500mg in 10mL vial into 10mL syringe
      • Draw 1 mL of drug into 9mL of saline in a 10mL syringe

Glen Simpson CRNA:

  • The Ketamine party phase is not fun in an OR or in the field
  • Don’t go through the party phase twice
  • Go big early and skip through the first one
  • Depending on the patient Benzo may not be good up front
  • Know everything about the drugs you are using
  • If there are multiple things in a bag the problem could be caused by multiple drugs
  • Mix your drugs to the same concentration every time

LTC(Ret.) Jim Reed CRNA:

  • Emergence Delirium
    • Never seen it in children
    • Usually associated with higher doses
  • Low dose Ketamine for PTSD 40mg/45mins
    • Arthritis also significantly improved
    • Improved outlook
    • Ketamine without versed felt like he was getting buried alive

ketamine-for-depression

  • Use a 60 drop per mL tubing or drip set and count drips easier
  • Ketamine is a Dissociative Anesthetic
    • Analgesia
    • Amnesia
    • No muscle relaxation

  1. You mention “Ketamine versed.” I have. Wen trying to find what this means but having no luck. Can you assist with definition please?

    1. Sorry for the confusion as they are 2 completely separate drugs often used to complement one another . Versed is a benzodiazapine sedative also known as Midazolam with Romazicon as it’s reversal agent, just like its close cousin, Diazepam (Valium).
      It has been known to be mixed in with Ketamine in either a bump syringe or in a bag for longer term sedation.
      You can also have a Ketamine drip and have midazolam in a syringe standing by for either amnestic effects or for sedation in the case that you encounter emergence delerium from the Ketamine.
      If you are a medic, be sure to ask your PA, Surgeon or med director how they want you to do it.
      And always… know all your drugs inside and out or don’t carry them.

      1. Thank you
        In Australia we do use Ketamine and Mudazolam together. Makes sense to me now.

        Great article

        Regards

        Paul
