   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.

   Behind the Drapes: Highlights of teaching sessions in the operating room. Ep 1: Airway Assessment - A Deeper Dive with Dr. John Veall.

   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.

    04 - Paralytics / Neuromuscular Blockade / Muscle Relaxants

    Neuromuscular Blockade: - Facilitates intubation - Facilitates better surgical conditions - Facilitates mechanical ventilation (i.e. ARDS, hyperventilating in increased ICP) Two Categories: - Depolarizing: ex. Succinylcholine (1-1.5mg/kg IV) depolarizes the muscle and prevents repolarization. - Non-depolarizing: ex. Rocuronium (0.6-1.2mg/kg IV) Outcompetes ACh for the receptor on the endplate.

    03 - Postoperative Nausea and Vomiting

    Post-op nausea and vomiting is associated with high levels of patient dissatisfaction, longer admissions and therefore higher costs to the medical system. Screen with the APFEL score + the other risk factors (younger age, type and length of surgery, anesthetic gases or nitrous exposure) 1+ risk factors? 2 prophylactic anti-emetics. 3+ risk factors? 3-4 prophylactic anti-emetics. For rescue therapy within 6 hours post-op, use a different agent. References: 1. Butterworth J, Mackey D, Wasnick J. Morgan & Mikhail’s Clinical Anesthesiology. 5th ed.

    Preoperative Physical Exam: 1. Inspect for factors indicative of difficult BVM, LMA, or Intubation. 2. Apply the 332-1 Rule (The 1 is the Upper Lip Bite Test which should equal about one pinky finger width of forward jaw protrusion) 3. Assign a Mallampati Score 4. Screen for neck mobility 5.
