    12 - Hypotension / Approach to Hemodynamic Instability in the OR

    VTDAT Approach This should complement teachings you've likely already received on an ABCDE approach. Three boxes: Anesthetic, Surgical, Patient Categories: Hypovolemic, Distributive, Cardiogenic, Obstructive, Mixed Use history, physical, non-invasive and invasive monitors, investigations (ECG, blood work, ultrasound, etc) to rule in or rule out your differential. Trial treatments. Assess response to treatments. Don't anchor, reconsider differential diagnosis if not improving. Have questions, comments, corrections, or concerns?

    11 - Post Dural Puncture Headache (PDPH) / Epidural Blood Patch

    PDPH is a recognised complication of neuraxial anesthesia. Around 4 minutes I misspoke and stated an 18G spinal needle - I meant epidural needle, I corrected myself the second time I stated it, sorry for the confusion!

    10 - Multimodal Analgesia / Treating Acute Post-Surgical Pain

    In this episode, we define multimodal analgesia and give a brief introduction to the many agents that can be utilised. Opioids are a mainstay of treating post-surgical pain and the goal of multimodal analgesia is not to avoid opioids (termed opioid-sparing analgesia) but to reduce the negative side effects while providing adequate post-surgical pain. The medications listed are those that are typically used in British Columbia, Canada and may differ from your regional practice. For example, we mention IV acetaminophen briefly, this is difficult to obtain in Canada (at least in British Columbia where we practice) although I am aware that it is quite cheap and widely used in other areas of the world. Apologies for the hissing - we had technical difficulties with the recording equipment. Have questions, comments, corrections, or concerns?

    09 - High Airway Pressure / An Approach to Unstable Patients and Anesthesia Emergencies

    We discussed the VTDAT approach to unstable patients in the OR (although this could also apply to out-of-OR situations). Vitals (Alert the Room) Temporize Differential Diagnosis Assessment Treatment We also discuss an approach to high airway pressure - patient to machine or machine to patient.

    08 - Difficult Airway and Algorithms

    We give an example of an "unanticipated" difficult airway situation along with a basic overview of some of the algorithm suggestions. I would strongly encourage you to check out the Vortex approach, the link is at the bottom of the references. Have questions, comments, corrections, or concerns?

    07 - Obstetric Anesthesia

    This episode focuses on an overview of physiological changes in pregnancy and how this can impact anesthesia. We discuss the preference for neuraxial anesthesia and use the ABCDE approach to cover some anesthetic considerations. Have questions, comments, corrections, or concerns?

    Behind the Drapes: Highlights of teaching sessions in the operating room. Ep 1: Airway Assessment - A Deeper Dive with Dr. John Veall. TLDR: Airway management is a complex interplay of anatomy, physiology, circumstance and human factors. Our assessment, preparation and training should reflect that.

    06 - Pediatric Anesthesia

    This episode focuses on general anesthesia in pediatric patients.  When organising your "considerations" - (I wouldn't worry about this much as an MSI3, but for any MSI4s preparing for electives this is a good thing to start practising) try to develop a system to maintain an organised approach. We introduce an ABCDE method in this episode.  Link to the website / app for Anesthesia Considerations:  https://www.anesthesiaconsiderations.com/ References:  1. Butterworth J, Mackey D, Wasnick J.
