    EMCrit 274 – Team Leadership with Cliff Reid

    Team leadership is hard [duh]. Teaching it to our trainees is even tougher. When you work in a team of true experts with established implicit communication, things just flow--giving the the team leader the impression that they actually know what the hell they are doing. The mark of a good team leader is how they handle a less than ideal team. I found a true master to interview on the topic of team leadership--friend of the show, Cliff Reid.

    EMCrit Wee – A Theoretical Model of the Pathophysiology of COVID-19 with Farid Jalali (Not a Single Thing Verified–Pure Musings)

    EMCrit Wee – A Theoretical Model of the Pathophysiology of COVID-19 with Farid Jalali (Not a Single Thing Verified–Pure Musings)

    Today on the podcast, my guest lays out a theoretical framework for the pathophysiology of the lung effects of COVID-19.

    Farid Jalali

    Dr. Farid Jalali received his Medical Degree from West Virginia University School of Medicine in 2012. He completed his postgraduate training in Gastroenterology at the University of California, Irvine Medical Center in 2018. Dr. Jalali has had extensive training and experience in diagnosing and treating a broad spectrum of GI and Liver disorders. He has a special focus on cancer prevention and spends a great deal of time educating and helping patients on how to prevent cancers in the GI tract and Liver. [@farid__jalali]

    Take Home Points from the Talk



    * Early endothelial stabilization, before hypoxia sets in, is key to prevent SARS-CoV-2 induced, excess Angiotensin II mediated, intense alveolar capillary vasoconstriction as well as the concomitant pro-inflammatory, pro-thrombotic endothelial milieu, all of which form the basis of lung

    injury in COVID19.

    * Once hypoxia sets in, supportive care should include early and aggressive endothelial stabilization interventions, properly dosed anticoagulation to prevent lung microvascular thrombi, HFNC, and awake prone position to redistribute flow away from the forming dorsal-predominant intrapulmonary shunts.

    * Alveolar capillary microvascular thrombi are not a pre-requisite for the severe lung injury in COVID19, but are a clear step in the wrong direction if allowed to be formed.

    * Lung's natural and physiologic protective response to SARS-CoV-2 induced alveolar capillary vasoconstriction and dead-space ventilation is characterized by alveolar hypocapnic bronchoconstriction at the level of the alveolar ducts to reduce a harmful alveolar expansion in these affected capillaries.

    * Naturally, unaffected capillaries and corresponding alveoli will have a higher redistribution of ventilation, will exchange more CO2 into alveolar space, and will therefore have hypercapnic bronchodilation.

    * This redistribution keeps the lung compliance preserved in the initial lung injury characterized mainly by dead-space ventilation, forming intrapulmonary shunts, without significant interstitial or alveolar edema.

    * Compensatory lower inspiratory volumes characterize the patient's response, associated with higher respiratory rate, and "shallow rapid breaths" without distress. [this has not been my experience--EMCrit]

    * This lower inspiratory volume is needed to prevent expansion of alveoli in the affected vasculopathic areas, as inappropriate expansion compounds the vasoconstriction in these affected alveolar capillaries.

    * This will result in a compensatory tendency to develop hypocapnea on blood gas analysis, often concomitant with hypoxia as intrapulmonary shunts also begin to form as lung injury progress.

    * Higher lung volumes, and positive pressure ventilation, disturb the fine balance maintained physiologically in the ventilatory redistribution pattern of the COVID1 9 lung, between high V/Q mismatch areas (poor perfusion, compensatory reduced ventilation to protect against the vasculopathy) and the compensating lower V /Q areas that safely receive higher ventilation in return.

    * Therefore, mechanical ventilation may result in worsening of dead-space ventilation by constricting alveolar cap...

    EMCrit 273 – Inhaled Pulmonary Vasodilators & Q&A with Sara Crager

    This episode continues on from last time's talk by Sara Crager on Right Ventricular Failure. This is a Q&A session with a focus on inhaled pulmonary vasodilators.

    Nitric Oxide

    Sara likes it through ETT or Hi-Flo NC (can also be done through BIPAP)

    Start at 20 ppm

    See results within 5-10 minutes

    Monitor with CVP

    Epoprostenol @ 0.05 mcg/kg/min

    Milrinone

    Get the vial, you want 1 mg/ml with 15 mls in vial



    5 ml (5 mg) q 6 hours (According to Dr. Crager--may be more frequent if symptoms rebound (down to q 3 hrs))



    Ideally use ultrasonic nebulizer



    onset ~15 minutes



    Must have filters on circuit



    LVOTO & RVOTO contraindication for the milrinone

    Nitro

    Need conc. of 1 mg/ml (standard bottle is 200 mcg/ml)



    Doses in studies range from 2.5-25 mcg/kg/min for 10 minutes or 50 ug/kg total given over 8 minutes (perhaps easiest to put 4-5 mg in neb and let it run)

    EMCrit 272 – Right Heart Failure with Sara Crager

    We did an amazing episode on EMCrit with Susan Wilcox on Right Heart Failure. However, this oft neglected ventricle deserves even more coverage giving how pesky it can be when it fails. So we brought Sara Crager, MD to Stony Brook to give Grand Rounds. You are going to love this lecture. Part 2 is a Q&A and will be released as a separate episode.

Asi Peretz ,

Unbelievably amazing!

Scott is one of the best lecturers I have listened to. He always keeps me interested. As a junior doctor in a busy ED outside of Cape Town. I find these podcasts informative, up to date with information and relevant to our day to day work in the ED. I look forward to my daily commute as I get to have Scott in the car with me. Amazing stuff. Please keep these coming!

Just epic!

I am a relatively junior Dr in South Africa. Only 1 full year out of our internship, currently working in a busy ED just outside of Cape Town. This podcast is just great. It makes me excited about emergency medicine and critical care, it challenges me to think about our habits and way of thinking in our ED and is presented in a really energetic and inspiring way so that my commute to work is something I look forward to. I arrive at work excited to tackle whatever comes through the door in the best possible way.
