Dr. Cooper a Professor Emeritus in the Faculty of Medicine at the University of Toronto. He spent his career as a Clinical anesthesiologist at University Health Network, Toronto General Hospital from 1981-2019. He was the founder and former Director of the Anesthesia Advanced Airway Fellowship at Toronto General Hospital and the Past President of The Society for Airway Management (SAM) from 2012-1...

Neuromuscular blocking agents are used to chemically paralyze skeletal muscle during surgery to:  Provide paralysis of the vocal cords for intubation  Enhance operating conditions for surgeons  How does skeletal muscle work normally?  An action potential triggers the release of acetylcholine into the neuromuscular junction, which binds to nicotinic receptors on the muscle and causes contraction. A...

Happy New Year! Airwayve is back to bring you tips for your anesthesia rotations. This episode highlights the importance of professionalism in anesthesia and provides 10 practical tips to help you succeed.  We thought this episode was quite timely as the second-year medical students at our institution, McMaster University, are beginning their clerkship journey. Our 10 tips for success are: 1. Be o...

Dr. Dolores McKeen grew up and did her medical training in Newfoundland. She moved to Halifax to further train at the IWK on a 2-year plan, and ended up staying in Nova Scotia for the last 21 years with her husband Roger, 3 adult children and a senior Yorkie-poo named Miss Molly! She has conducted research in the areas of post-operative pain management, obstetric anesthesia and health outcomes. He...

This is the final episode of this series on general anesthesia! PACU handover can seem complicated, but it's ultimately about transferring professional and care responsibility for your patient after surgery. For this week's episode, remember the acronym "ISBAR" - as always, check out our step-by-step approach below: ID + Introduction : introduce yourself, the surgery team and y...

What is emergence? The time from discontinuation of an anesthetic to when the patient can make a non-reflex response to verbal command   Maneuvers to improve the elimination of inhaled anesthetics : Increase FiO2 Increase gas flow rate Increase PEEP to prevent atelectasis Factors that affect emergence: Patient factors (e.g. obesity, advanced age, hepatic or renal insufficiency)  Drug factors (e.g....

Two overarching goals for the maintenance phase of an anesthetic: Maintain appropriate depth of anesthetic Maintain patient’s stability Inhalational Anesthetics Volatile agents: sevoflurane and desflurane (most common), isoflurane (less common) Nitrous oxide: low potency, can be used in MH, flammable Minimum alveolar concentration (MAC): alveolar concentration of a specific inhaled agent that inhi...

Overall approach to a difficult airway Always ask for help! The goal is oxygenation, not intubation Your first attempt is your best attempt Don’t panic! Preoperative Assessment (check out Episode 1 of the series for a review!) Identify risk factors for a potentially difficult airway: Difficult ventilation Difficult intubation Difficulty with patient cooperation/consent Difficult cricothyrotomy One...

Check out this great video which summarizes the steps below : https://www.youtube.com/watch?v=8AOB2PtHfVM&ab_channel=InterAnest Here are a few key steps in airway management:  Ask yourself:  Will I be able to mask ventilate? Will I be able to perform laryngoscopy, directly or indirectly? Will I be able to intubate this patient? Is there a significant aspiration risk? History and physical : Che...

In this episode, we discuss induction, the stage of general anesthesia that encompasses the onset of sedation, amnesia, analgesia, and sometimes akinesia. The anesthesiologist’s goals are to achieve induction smoothly and safely, maintaining the patient’s hemodynamic stability throughout. Step 1: Place monitors on patient (see Episode 2 show notes for a list of the CAS’ required monitors). *Clinic...

In this episode, we discuss setting up the operating room for a general anesthetic. The mnemonic SOAP-IM(S) is a helpful checklist for organizing all of the necessary equipment.  1. Suction Is the suction equipment (Yankauer/suction system) present and working? 2. Oxygen: Check circuit tubing, gas analyzer tubing, filter, face mask Check for availability of back-up O2 tank 3. Airway:  Have a plan...
